Passive components for Morocco’s automotive wiring and electronics makers, sourced from Hong Kong, come down to one test: does your 25 V X7R line have an automotive-series twin? As at 23 September 2026, 23 of our 28 stocked 25 V X7R lines do. Five have none, and no automotive-series part is on the shelf.
Morocco’s car-wiring exports are worth almost as much as its car building, and a plant that builds harnesses and control modules buys the same 25 V capacitor over and over. Venatech Limited, an authorised Walsin distributor in Hong Kong, holds the Walsin Technology (Walsin) multilayer ceramic capacitor export: 24,026 rows, 23,601 distinct part numbers. This post is for a purchasing or design engineer at a Moroccan wiring, connector or electronics-assembly site who has an incumbent 25 V part and wants Walsin candidates with every difference stated. Every part number below is real. Every count is ours. Every news statement names its source, its date and the day we fetched it, 23 October 2026.
What did Morocco’s car-wiring figures show in 2026?
Wiring grew, but car building grew faster. AGBI reported in June 2026 that Moroccan vehicle exports reached nearly 58 billion dirham in January to April 2026, up 18.6 percent on the same months of 2025, and that car wiring was worth 22 billion dirham against 19 billion a year earlier. Car building rose from 17.8 billion to around 24 billion dirham over the same four months.
The same report says Morocco reached one million cars in 2025, citing the Industry and Trade Minister, and that the 2026 target is again one million cars. It names no component, no shortage and no supplier, and we draw no conclusion about which parts any Moroccan company buys. The page carries no day; its address and its reference to January to April data place it in June 2026. We have no relationship with any firm it mentions.
| Point | What the source says | Source date | Match / mismatch |
|---|---|---|---|
| Vehicle exports | Nearly 58 billion dirham, January to April 2026, up 18.6 percent | AGBI, June 2026 | Mismatch with any component claim: no part is named |
| Car wiring | 22 billion dirham, up from 19 billion | AGBI, June 2026 | Match for context only: a harness buys board-level passives |
| Car building | About 24 billion dirham, up from 17.8 billion | AGBI, June 2026 | Match for context only |
| Output | One million cars in 2025; same target for 2026 | AGBI, June 2026 | Mismatch: no electronics volume given |
How many stocked 25 V X7R lines have an automotive-series twin?
23 of 28. We joined every one of our 764 stocked MLCC lines to the Walsin export (23 September 2026 snapshot) and took the 28 general purpose lines rated 25 V in X7R. Matching on size, dielectric, capacitance, tolerance and voltage, 18 have an AEC-Q200 MT-series twin, 18 have an MG-series twin, 13 have both, 5 have only MT, 5 have only MG and 5 have neither. The union is 23.
None of the twins is on the shelf: 0 of the 764 stocked MLCC lines sit in an MT, ST or MG series. A twin is a catalogue match, not a stock claim. The MT series is the one whose Walsin sheet describes AEC-Q200 compliance; the MG series is named “without AEC-Q200 certification”. We have not seen this counted anywhere.
| Group of the 28 stocked lines | Lines | Match / mismatch |
|---|---|---|
| Twin in MT (AEC-Q200 compliant) | 18 | Match on five fields; mismatch on series grade, sometimes on height |
| Twin in MG (no AEC-Q200 claim) | 18 | Match on five fields; mismatch: no AEC-Q200 claim, tolerance cell stored as a number |
| Twin in both | 13 | Two grades to choose from |
| Twin in MT only / MG only | 5 / 5 | One grade only; the other is mismatch |
| No automotive twin | 5 | Mismatch: stay on commercial grade or change the specification |
Which worked part numbers show the twins, and what differs?
Start with the stocked 0603 line 0603B104K250: 100 nF, plus or minus 10 percent, 25 V, X7R. MT18B104K250, ST18B104K250 and MG18B104K250 share its size, value, tolerance, voltage and thickness of 0.80 plus or minus 0.07 mm. The 1210 case is different: MT32B106K250 is 2.50 mm thick against 2.00 mm for the stocked 1210B106K250. The last column is for your incumbent part.
| Stocked line | Automotive-series part | Series | Match / mismatch | Your incumbent |
|---|---|---|---|---|
0402B103K250 |
MT15B103K250 |
MT | Match on size, 10 nF, 10%, 25 V, 0.50 mm; mismatch on series grade | |

MG | Match on the same fields; mismatch: no AEC-Q200 claim | |
0603B104K250 |

MT32B106K250 |
MT | Match on 10 uF, 10%, 25 V; mismatch: 2.50 mm against 2.00 mm | |
0201B471K250 |
MT03B471K250 |
MT | Match on 470 pF, 10%, 25 V, 0.30 mm; no MG twin | |
0603B394K250 |
none | Mismatch: no automotive-series part at 390 nF, 10%, 25 V |
A plain join misses half of this. In the MG series 653 of 785 part numbers store the tolerance as a negative decimal such as -0.1, where the other series write plus or minus 10%. The letter in the part number settles it: K sits on every -0.1 row. Our how to cross-reference an MLCC post shows the join; the MT against MG comparison shows the grades.
What do Walsin’s documents say about wiring harnesses?
Nothing. We converted all 28 Walsin datasheets we hold, 451 pages, to text: the words wiring and harness appear in 0 of 28 files, while automotive appears in 10 and AEC-Q200 in 8. Walsin’s wording for its automotive capacitors is “compliant”, never “certified”, and we do not upgrade it.
A sheet that says automotive is not a statement about a Moroccan plant, a customer’s approval list or a harness application. Venatech makes no qualification claim of its own.
What will we not tell you about Morocco?
Anything about Moroccan or European customs, free-zone, origin or automotive-programme rules. We hold no office, entity or stock in Morocco; our locations are Hong Kong, Shenzhen, Singapore and Jiangmen, with Chengdu in preparation. We state no duty rate, transit time, carrier or lead time, we give no legal or customs advice, and you should confirm with your compliance team. We do not say which firms are short of any part.
How Venatech helps
Start with the cross-reference. Paste your incumbent 25 V part into the free cross-reference tool, which decodes 18 manufacturers’ part numbers across 800,000+ crossable parts and lists Walsin candidates with match and mismatch fields, or upload a harness-module bill of materials to the BOM checker, up to 500 part numbers or an Excel or CSV file. The Hong Kong ready-stock list is a dated snapshot, 23 September 2026, and is not live-synced. Walsin is the only line we are authorised for; Stackpole and Viking are lines we supply. We work from Hong Kong, in small lots, and you can request a quote through the site. We offer lot and date-code traceability and a certificate of conformity per shipment on request. We hold neither ISO 9001 nor IATF 16949. The tables above came from our own export; the MLCC range lists the families. Qualification stays with you.
The short version
For a Moroccan wiring or electronics site, a 25 V X7R line is more likely to have an automotive-series twin than not: 23 of our 28 stocked lines do, 18 in MT, and 5 have none. None of the twins is on the shelf, and 0 of 28 Walsin datasheets mention wiring or harnesses. Confirm against both datasheets and qualify in your own circuit.
Send us one 25 V capacitor from your bill of materials and we will return the Walsin candidates with every difference stated. Does your approval list name a series, or only a value?

Frequently asked questions
What did AGBI report about Moroccan car wiring in 2026?
AGBI reported in June 2026 that car wiring exports were worth 22 billion dirham in January to April 2026, against 19 billion a year earlier, and that Morocco reached one million cars in 2025. It names no component or shortage, and we draw no conclusion about which parts any company buys.
How many stocked 25 V X7R lines have an automotive-series twin?
23 of 28, as at 23 September 2026. Eighteen have an AEC-Q200 MT twin, 18 have an MG twin, 13 have both, and 5 have neither. The twins match on size, dielectric, capacitance, tolerance and voltage. None of them is on the shelf, and a twin is not a qualification.
Is the MG series AEC-Q200 qualified?
No. Walsin names it the automotive series without AEC-Q200 certification. Only the MT series is described as AEC-Q200 compliant. Walsin writes compliant, never certified, and we do not upgrade it. Ask Walsin in writing for the qualification report covering the exact MT part number you intend to use.
Why does a plain join miss the MG twins?
In the MG series, 653 of 785 part numbers store the tolerance as a negative decimal such as -0.1, where other series write plus or minus 10 percent. A text match on tolerance finds none. The K in the part number identifies the plus or minus 10 percent rows, which fixes the join.
Do Walsin datasheets mention wiring harnesses?
No. We converted all 28 datasheets we hold, 451 pages, to text. Wiring and harness appear in 0 of 28 files. Automotive appears in 10 and AEC-Q200 in 8. A sheet that says automotive is not a statement about your application or your customer’s approval list.
Do you give Moroccan customs or free-zone advice?
No. We hold no office, entity or stock in Morocco and state no duty rate, transit time or lead time. We give no legal or customs advice; confirm with your compliance team. We supply parts from Hong Kong, in small lots, with lot and date-code traceability.
