Passive components for South Africa need a fully pinned part number when the Durban port is slow. One 100 nF, 50 V, X7R specification maps to 59 rows and 51 part numbers in Walsin’s export, across six case sizes and six series. We hold 6 of the 51 on the Hong Kong shelf as at 23 September 2026.
Venatech Limited, an authorised Walsin distributor in Hong Kong, holds the Walsin Technology (Walsin) parametric exports, including 24,026 MLCC rows in 00_ALL_MLCC_parts_combined.xlsx. This post is for a buyer or engineer in South Africa whose inbound containers pass through Durban and who cannot afford to order the wrong variant of a common capacitor. Every part number is real and every count is ours. Where the post states a port fact it names the source, the source date and the day we read it, 21 October 2026.
What is happening at the Durban Gateway Terminal?
A terminal that handles close to half of South Africa’s container traffic has been slow since August 2026. The South African Freight and Logistics Association reported that average Durban port calls rose from under 5 days in late June to over 12 days by late August, and that weekly throughput fell 26% after the terminal moved to a new operating system. The same report says manufacturers are struggling to receive components and raw materials.
The terminal is the Durban Gateway Terminal, formerly Pier 2, run by ICTSI under a 25-year partnership with Transnet that began on 1 January 2026. The Association’s figures, republished by FreshPlaza on 27 August 2026 from Moneyweb, put anchorage waits at about 80 hours in July and 166 hours, about seven days, in early August, with 116 hours at berth. Berth calls fell from 34 in May to 19 in August. The causes it cites are straddle carrier shortages, equipment breakdowns, yard and truck congestion, and coordination problems.
In October the story moved to government. The Transport Minister met the operator, and BusinessTech reported on 6 October 2026 that average anchorage had roughly doubled to nearly six days since the takeover, tied mainly to the new Navis N4 system and slow equipment replacement. EWN reported on 5 October 2026 that average waiting had improved to about 8.3 days, still far above a 24-hour target, and that the minister blamed the changeover with bad weather in August making it worse. The measures differ between sources and we quote each as stated. WorldCargo News said on 6 October 2026 that severe vessel and landside delays continued, and a Daily Maverick report carried by allAfrica on 18 October 2026 said delays were continuing.
What does a delayed container change for a component buyer?
It raises the cost of a wrong order, because a correction cannot catch the same container. The Association says shipping lines are charging storage, demurrage and detention on containers not collected on time and that those costs are being passed down the chain, so the cost of a mistaken part number now includes the time it sits. We state no cost figure; none is in our data.
What follows is our view, not the sources’. When the lead time you cannot see gets longer, you want fewer open variables per line on the order. A capacitor line is the clearest case, because a value and a voltage do not decide a part. We checked how many Walsin parts answer the most common ceramic capacitor brief we know, 100 nF at 50 V in X7R, and the answer is far more than one. Our post on one specification, 13 Walsin parts shows the same effect on a smaller brief.
How many Walsin parts answer a 100 nF, 50 V, X7R brief?
59 rows, 51 part numbers, six case sizes. We parsed all 24,026 rows of the MLCC export and filtered 100 nF, 50 Vdc, X7R: 59 rows come back, 51 distinct part numbers, from six series (General Purpose 23 rows, MT 14, MG 8, SH 8, ST 3, SG 3) and six case sizes. We have not seen this counted anywhere.
| Case size | Rows | Distinct part numbers | On the Hong Kong shelf, 23 September 2026 | Match / mismatch within the brief |
|---|---|---|---|---|
| 0402 | 9 | 6 | 1 | Match on value, voltage, dielectric; mismatch inside the size: thickness 0.50 ±0.05 mm or 0.50 ±0.20 mm |
| 0603 | 13 | 13 | 3 | Match on the three fields; thickness 0.80 +0.15/-0.10 mm on general parts, 0.80 ±0.30 mm on soft termination |
| 0805 | 18 | 14 | 1 | Match on the three fields; mismatch inside the size: thickness 0.80 mm or 1.25 mm |
| 1206 | 12 | 11 | 1 | Match on the three fields; thickness 0.80 mm on general parts, 0.80 or 1.25 mm on soft termination |
| 1210 | 5 | 5 | 0 | Match on the three fields; 0.95 mm; none on the shelf |
| 1812 | 2 | 2 | 0 | Match on the three fields; 1.25 mm; none on the shelf |
The difference between 59 and 51 is the real finding. Eight part numbers appear twice, each with a different thickness: 0402B104J500, 0402B104K500, 0402B104M500, 0805B104J500, 0805B104K500, 0805B104M500, MT21B104K500 and SH31B104J500. A lookup by part number alone returns two rows for each, and the Thickness field is the only thing that tells them apart. A 0805 part at 0.80 mm and one at 1.25 mm are not the same part on a tight stack-up. Our post on building a BOM that survives a shortage argues for settling these fields before the order, not after.
Which Walsin part do you pin on the purchase order?
The one that matches your four fixed fields and the field you have not yet fixed. Take a 0805, 100 nF, plus or minus 10%, 50 Vdc, X7R brief: 14 Walsin part numbers at 0805 fit the value and voltage, and the table lists five of them, plus one 1206 neighbour, with a column for your incumbent so you can see where each one differs.
| Walsin part | Series | Size and thickness | Your incumbent part | Match / mismatch with the brief |
|---|---|---|---|---|
0805B104K500 |
General Purpose | 0805, 0.80 mm and 1.25 mm (two rows) | ______ | Match on size, value, tolerance, voltage, dielectric; mismatch unless you pin the thickness |
MT21B104K500 |
MT | 0805, 0.80 mm and 1.25 mm (two rows) | ______ | Match on the five fields; AEC-Q200 in the series name; thickness still open |
ST21B104K500 |
ST | 0805, 1.25 mm | ______ | Match on the five fields; mismatch: soft termination, 1.25 mm only |
SH21B104K500 |
SH | 0805, 1.25 mm | ______ | Match on the five fields; mismatch: soft termination, no automotive label |
MG21B104K500 |
MG | 0805, 0.80 mm | ______ | Match on size, value, voltage; mismatch: not AEC-Q200, and the tolerance column reads -0.1 |
1206B104K500 |
General Purpose | 1206, 0.80 mm | ______ | Mismatch on size; shown as the next case size up on the same value |
Read the 0805 General Purpose row twice. It is on our shelf, and it has two thicknesses. Say which one you want in the order text. Our post on MT against MG series explains the automotive labels. Confirm against both datasheets and qualify in your own circuit.
What do we hold in stock for this specification?
Six part numbers, in four of the six case sizes. We matched our stock list as at 23 September 2026 against the export: 6 of the 51 part numbers are held, 0402B104K500, 0603B104K500, 0603B104M500, 0805B104K500, 1206B104K500 and SH18B104K500, and none is in an automotive series.
Those six are a general-purpose tolerance-plus-or-minus-10% line in four sizes, one plus or minus 20% line at 0603 and one soft termination line. The two thickness-split part numbers among them, 0402B104K500 and 0805B104K500, are the ones where a purchase order that omits the thickness is open to a second reading. The stock list is a dated snapshot and moves; our ready stock page shows what is held now. Held stock does not remove a port delay on your side, and we state no transit time, carrier or arrival date.
What will we not tell you about South African import and shipping?
Anything about duty, customs, routing or timing. We state no duty rate, customs procedure, carrier, routing or transit time for South Africa, we give no legal or customs advice, and we hold no office, entity or stock in South Africa. Ask your freight forwarder which port and which terminal your container will use.
Our locations are Hong Kong, Shenzhen, Singapore and Jiangmen, with Chengdu in preparation. We hold no ISO 9001 or IATF 16949 for Venatech, and we do not claim them. What we can show is checkable: an authorised Walsin distributor in Hong Kong, lot and date-code traceability, a certificate of conformity per shipment on request and original sealed Walsin packaging. The MLCC range lists the families.
How Venatech helps
We help by removing open fields before the order, not after. Paste your incumbent 100 nF part into the free cross-reference tool, which decodes 18 manufacturers’ part numbers across 800,000+ crossable parts, and it returns Walsin candidates with match and mismatch fields, including the differences in thickness that a value search hides. For a whole list, the BOM page checks up to 500 part numbers, or an Excel or CSV file, against the same engine. Worked example from our own export: paste a 0805 100 nF 50 V part and the rows of the table above come back, each with its differences stated.
Walsin is our only authorised line; Stackpole and Viking are lines we supply. We work from Hong Kong, in small lots, and we cross parts for you if you send a list. Request a quote through the site. Qualification stays with you.
The short version
Durban is slow, and the average port call was reported above 12 days by late August. In Walsin’s data, one common capacitor brief has 51 part numbers and eight of them have two thicknesses. Pin the series, the case size and the thickness on the order. We hold 6 of the 51 as at 23 September 2026.
Send us one capacitor line from your next order and we will return the Walsin candidates, the thickness variants and the gaps, field by field. If your purchase order leaves a field open, who decides which variant arrives?

What is happening at the Durban Gateway Terminal?
Delays since August 2026. The South African Freight and Logistics Association reported average Durban port calls above 12 days by late August, against under 5 in late June, and a 26% fall in weekly throughput after a new operating system went in. Reports in October say delays continued. Check a current source.
How many Walsin parts answer a 100 nF, 50 V, X7R brief?
59 rows and 51 distinct part numbers in our export, across six case sizes and six series. Eight part numbers appear twice with different thicknesses. A value and voltage search therefore does not identify one part.
Which Walsin part fits a 0805, 100 nF, 50 V, X7R, plus or minus 10% brief?
0805B104K500 is General Purpose and MT21B104K500 carries the AEC-Q200 label in its series name; both come in 0.80 mm and 1.25 mm rows. ST21B104K500 and SH21B104K500 are soft termination at 1.25 mm. Confirm against both datasheets and qualify in your own circuit.
Why does the thickness matter on a purchase order?
Because the same part number can return two rows with different thicknesses, such as 0.80 mm and 1.25 mm at 0805. If the order omits the thickness, the variant is open to a second reading. State the thickness in the order text.
Which of these parts do you hold in Hong Kong stock?
As at 23 September 2026, 6 of the 51: 0402B104K500, 0603B104K500, 0603B104M500, 0805B104K500, 1206B104K500 and SH18B104K500. None is in an automotive series. Stock moves, so ask for the current position.
Do you state South African customs, routing or transit times?
No. We give no legal or customs advice and state no duty, carrier, routing or transit time. We hold no office or stock in South Africa. Ask your freight forwarder and your compliance team.
