Murata, TDK and Samsung MLCC Cross Reference to Walsin in Vietnam: 2 Common 0402 Lines, 49 Walsin Candidates, and How Venatech’s VenaMatch Crosses Them

An MLCC cross reference from Murata, TDK or Samsung to Walsin is a field-by-field match on case, dielectric, value, tolerance, voltage and thickness. For two common 0402 lines in Vietnamese builds, Walsin Technology (Walsin) lists 49 candidates and 6 sat on our Hong Kong shelf. Venatech, the authorised Walsin distributor in Hong Kong, does it free with VenaMatch.

Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this for a component engineer or buyer in Vietnam whose BOM is full of Murata, TDK and Samsung capacitor numbers and who wants a second source that will pass incoming inspection. We decoded the three makers’ part-number formats for two everyday lines, matched them against Walsin’s MLCC export, 00_ALL_MLCC_parts_combined.xlsx (23,601 distinct part numbers), and checked our stock list as at 23 September 2026. The market figures name their source and the day we fetched them, 11 November 2026.

Why is MLCC cross reference a live task for Vietnam’s electronics makers?

Because Vietnam’s electronics output keeps rising. According to VOV on 9 November 2026, citing preliminary Vietnam Customs data, Vietnam exported 149.4 billion US dollars of computers, electronic products and components in the first ten months of 2026, up 71% year on year, and 57.6 billion US dollars of phones and components, up 18.4%.

Those are the customs figures, not ours. The engineering consequence we draw is ours: boards built at that pace carry hundreds of MLCC lines each, and a plant that can cross a line to a second maker in minutes rather than days keeps its own schedule. We say nothing about any company’s suppliers or purchasing.

How do Murata, TDK and Samsung encode the same 0402 capacitor?

In three different orders, carrying the same six fields. We decoded one 0402 X5R 1 µF 10 V ±10% line as each maker writes it; none of the three numbers is in the Walsin export, which is why the decode has to happen first.

Field	Murata GRM155R61A105KE15D	TDK C1005X5R1A105K050BB	Samsung CL05A105KP5NNNC	Walsin 0402X105K100
Case	15 = 1.0 x 0.5 mm (0402)	1005 (metric 0402)	05 = 0402	0402
Dielectric	R6 = X5R	X5R	A = X5R	X = X5R
Value	105 = 1 µF	105 = 1 µF	105 = 1 µF	105 = 1 µF
Tolerance	K = ±10%	K = ±10%	K = ±10%	K = ±10%
Voltage	1A = 10 V	1A = 10 V	P = 10 V	100 = 10 V
Thickness	5 = 0.5 mm	050 = 0.50 mm	5 = 0.5 mm	0.50 ±0.05 mm
Match / mismatch vs the Walsin part	Match on all six fields	Match on all six fields	Match on all six fields	reference

The three source numbers are competitor numbers and do not appear in the Walsin export; the Walsin number does, and it was on our shelf as at 23 September 2026. Confirm each maker’s code against its own current catalogue before you release a cross, because suffixes for packaging and special specification differ by maker.

Which Walsin parts cross a 0402 X5R 1 µF 10 V line?

One exact match, and a short list around it. We counted 13 Walsin X5R part numbers at 1 µF in 0402, from 6.3 V to 25 V, and 3 were on our stock list as at 23 September 2026: 0402X105K6R3, 0402X105K100 and 0402X105K160.

• Exact: 0402X105K100, 10 V, ±10%, 0.50 mm, stocked.
• Higher voltage, same footprint: 0402X105K160 at 16 V, stocked, and 0402X105K250 at 25 V. A higher rating gives DC bias headroom on a 5 V or 3.3 V rail; check the bias curve.
• Thinner: TT15X105K6R3 at 0.30 mm, but only 6.3 V, so a mismatch on voltage for a 10 V line.
• Soft termination: SH15X105K6R3, also 6.3 V.

Which Walsin parts cross a 0402 X7R 100 nF 16 V line?

Several, including automotive grade. For the line Murata writes as GRM155R71C104KA88D, TDK as C1005X7R1C104K050BB and Samsung as CL05B104KO5NNNC, none of which is in the Walsin export, we counted 36 Walsin X7R part numbers at 100 nF in 0402, from 6.3 V to 50 V; 3 were on our shelf as at 23 September 2026.

We checked every candidate against our snapshot: across both lines that makes 49 Walsin candidates, 6 of them stocked. Our walkthrough of how to cross-reference an MLCC shows the same method on other values.

What should a Vietnamese team check before approving the cross?

Six fields plus the ones the part number hides. Our approval checklist, built from the 49-candidate count above, has 9 checks:

1. Case size, in inches or millimetres, written out.
2. Dielectric code, X5R vs X7R vs C0G.
3. Capacitance and tolerance.
4. Rated voltage, never lower than the original.
5. Thickness and its tolerance band, for pick-and-place and low-profile spots.
6. Termination type, standard or soft.
7. Grade, commercial or AEC-Q200, when the board goes into a vehicle.
8. DC bias behaviour on your rail for Class II parts.
9. Packaging: reel size and quantity for your feeders.

The first five are in every part number; the last four need the datasheet. A match on export fields is a candidate for your own evaluation, not an approved substitution.

How can Venatech help a Vietnamese team cross a BOM?

How Venatech helps: you paste the Murata, TDK or Samsung numbers and get Walsin candidates back. Venatech Limited is Walsin’s authorised distributor in Hong Kong; our free VenaMatch tool decodes 18 manufacturers’ part numbers and crosses 800,000+ parts to Walsin, field by field, with every difference stated.

Paste up to 500 part numbers into the cross-reference tool, drop your Excel or CSV, and filter by commercial or automotive grade or for soft termination. Upload a whole BOM to request a quote. The ready-stock list is a Hong Kong snapshot dated 23 September 2026 and held the 6 parts named above; for the rest, request a quote and we source through our authorised Walsin channel. Small lots from Hong Kong, no lead-time or stock promise. The MLCC range lists the families, and the Samsung and TDK family guides go deeper. We will not tell you a part is equivalent. We will show you where it differs.

The short version

Murata, TDK and Samsung write the same 0402 capacitor in three orders, and all three decode to one Walsin number. For the 0402 X5R 1 µF 10 V and X7R 100 nF 16 V lines common in Vietnamese builds, Walsin lists 49 candidates, and the two exact matches, 0402X105K100 and 0402B104K160, were on our Hong Kong shelf.

Paste your Murata, TDK or Samsung MLCC lines into VenaMatch, or send us the BOM, and we will return the Walsin matches with every difference stated. Which line on your board has only one approved source today?
