For automotive electronics in Romania, the Walsin Technology (Walsin) automotive resistor arrays come in two sizes, and only one lines up with the general list: all 693 automotive 0603 arrays have a general twin on every field, while none of the 693 at 0402 does, because their TCR is 300 ppm against 200 ppm. None is on the shelf.
Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this for a design or sourcing engineer at a Romanian automotive electronics plant, in Cluj or elsewhere, who has a four-element pull-up or divider array on an ECU bill of materials. It comes from the Walsin thick-film array export (7,250 rows, 7,250 distinct part numbers) and our stock list as at 23 September 2026. Every part number is real. Market facts name their source and the day we fetched it, 10 November 2026.
What did Romanian car plants report for the first half of 2026?
Output fell at both plants. According to Romania Insider on 13 July 2026, updated 12 August 2026, Romania’s two car plants built 247,972 vehicles in the first half of 2026, down 12.7 percent year on year, with Dacia at 129,404 (down 18 percent) and Ford Otosan at 118,868 (down 6.4 percent).
Those are the reporter’s figures, not ours. Cars are assembled at Mioveni and Craiova, not in Cluj, where the electronics side is represented by a Bosch plant that Ziarul Financiar reported on 6 September 2021 as opening a third production hall for automotive electronic components, an investment reported at fifty-five million euro, with more than 3,100 people employed. That report is five years old and we found no 2026 volume for the site, so we say nothing about what it makes or buys today.
Which Walsin 10 kilohm arrays cross an automotive, 0402, 200 ppm brief?
None matches all four fields. We filtered the array export to 10 kilohm, plus or minus 1 percent, four-element convex arrays and found 6 part numbers across the two sizes; 0 matches an automotive, 0402, 200 ppm brief, because the automotive 0402 part is rated 300 ppm.
Put your incumbent in the last column.
| Walsin part | Description | On shelf 23 Sep 2026 | Match / mismatch with the brief | Your incumbent |
|---|---|---|---|---|
MA04X1002FTL |
Array 0402 x 4, convex, automotive, 10 kilohm, plus or minus 1 percent, 300 ppm, 1/16 W | No | Match on series, size, value and tolerance; mismatch: TCR is 300 ppm, looser | |
WA04X1002FTL |
Array 0402 x 4, convex, general, 10 kilohm, plus or minus 1 percent, 200 ppm, 1/16 W | No | Match on size, value and TCR; mismatch: general series, not automotive | |
WA04X1002FTLJ |
Array 0402 x 4, convex, general, 10 kilohm, plus or minus 1 percent, 200 ppm, 1/16 W | No | Match on size, value and TCR; mismatch: general series, J-suffix part number | |
MA06X1002FTL |
Array 0603 x 4, convex, automotive, 10 kilohm, plus or minus 1 percent, 200 ppm, 1/10 W | No | Match on series, value, tolerance and TCR; mismatch: 0603 size, 1/10 W | |
WA06X1002FTLJ |
Array 0603 x 4, convex, general, 10 kilohm, plus or minus 1 percent, 200 ppm, 1/10 W | No | Match on size and TCR at 0603; mismatch: general series, not 0402 | |
WA06X1002FTL |
Array 0603 x 4, convex, general, 10 kilohm, plus or minus 1 percent, 100 ppm, 1/10 W | No | Mismatch: general series, 0603 size, tighter 100 ppm |
A match in the table is a match on the export fields, no more. Confirm against both datasheets and qualify in your own circuit. Our guides to chip resistor arrays and to tolerance, TCR and dielectric codes explain the fields.
Does the automotive 0402 array differ from the general one?
Yes, on TCR and nowhere else. We compared the 693 automotive 0402 x 4 rows with the general 0402 x 4 rows on size, resistance, tolerance, rated power and TCR: 0 of 693 have a twin, because the 571 automotive rows at plus or minus 1 percent are rated 300 ppm and every general row at that tolerance is rated 200 ppm.
The other 122 automotive 0402 rows are 121 at plus or minus 5 percent, also 300 ppm, and one zero-ohm jumper. The general 0402 x 4 convex list has 1,399 rows, spelled “Convex type” on 706 and “Convex Type” on 693, which a text filter on the series name treats as two lists. We have not seen this TCR split counted anywhere.
Why does the 0603 array line up when the 0402 one does not?
Because the 0603 automotive rows copy a general TCR. All 693 automotive 0603 x 4 rows match a general row on size, resistance, tolerance, rated power and TCR: 571 at plus or minus 1 percent and 121 at plus or minus 5 percent, all 200 ppm and 1/10 W, plus one jumper.
So an ECU designer who needs the automotive series can move from a 200 ppm general 0402 array to the automotive 0603 array without changing the electrical fields, but the footprint grows, and the 0603 part is rated 1/10 W where the 0402 part is 1/16 W. A designer who needs 0402 and 200 ppm in the automotive series will not find it in this export.
What does the Hong Kong shelf hold in resistor arrays?
One general array and no automotive one. Of the 1,125 distinct part numbers on our stock list as at 23 September 2026, 1 is a resistor array, WA04X300 JTL (0402 x 4, plus or minus 5 percent, 30 ohm, 200 ppm), and 0 are among the 1,386 automotive array rows.
So every automotive array in this post is a to-order enquiry. The ready-stock list is a dated snapshot, never live-synced, and the chip resistor range lists the families. We give no lead time and no stock promise.
What will we not tell you about Romanian automotive electronics?
Anything about your ECU, your qualification or your customer’s approved list. We hold no Walsin array datasheet, and the export labels 1,386 rows “Automotive” without stating a qualification, so every count is catalogue coverage, not an AEC-Q200 statement.
We hold no ISO 9001 or IATF 16949 certificate, and Venatech makes no qualification claim of its own about any part. We hold no office, entity or stock in Romania; our locations are Hong Kong, Shenzhen, Singapore and Jiangmen, with Chengdu in preparation. We give no legal, customs or conformity advice; confirm with your compliance team.
Why do buyers in Romania choose Venatech?
Because we show which fields move. Venatech Limited is an authorised Walsin distributor in Hong Kong, and the Walsin array export is 7,250 part numbers, of which 1,386 are automotive and 693 of those, at 0402, carry a TCR that no general row shares.
A Romanian buyer gets a Hong Kong team that welcomes small lots, answers cross-reference questions field by field, and says plainly when the automotive part is looser than the general one. Our VenaMatch tool decodes 18 manufacturers’ part numbers and covers 800,000+ crossable parts, and every candidate comes back with each field marked match or mismatch.
How can Venatech help a Romanian automotive electronics maker?
How Venatech helps starts with a free paste box. The cross-reference tool accepts up to 500 part numbers or an Excel or CSV file and shows Walsin candidates with each field marked match or mismatch. Load a whole BOM for a check. The ready-stock list is a Hong Kong snapshot dated 23 September 2026.
Worked example from our own export: the 10 kilohm, 0402, automotive, 200 ppm brief returned 0 exact parts among 6 candidates, none stocked. Walsin is the only line we are authorised for; Stackpole and Viking are lines we supply. We serve from Hong Kong in small lots, we help cross-reference, and you request a quote through the site.
The short version
For a Romanian automotive electronics maker, an array is a TCR question: the automotive 0402 x 4 list is 300 ppm, the general one 200 ppm, 0 of 693 rows share both, and the automotive 0603 list lines up on all 693. Name the size, the series and the TCR.
Send us one resistor array line from your BOM, with the size, series, TCR and element power you can accept, and we will return the Walsin parts with every difference stated. If your ECU drawing says automotive, 0402 and 200 ppm, do you know that no Walsin array row offers all three?

Frequently asked questions
How many cars did Romania build in the first half of 2026?
Romania Insider reported on 13 July 2026 that the two car plants built 247,972 vehicles, down 12.7 percent year on year: Dacia 129,404, down 18 percent, and Ford Otosan 118,868, down 6.4 percent. These are the publisher’s figures, not ours.
Does the Walsin automotive 0402 resistor array match the general one?
Not on TCR. We compared 693 automotive 0402 x 4 rows with the general rows on size, value, tolerance, power and TCR, and 0 match, because the automotive rows are 300 ppm and the general rows at plus or minus 1 percent are 200 ppm.
Does the automotive 0603 resistor array have a general twin?
Yes. All 693 automotive 0603 x 4 rows match a general row on size, resistance, tolerance, rated power and TCR. The automotive 0603 part is rated 1/10 W against 1/16 W at 0402, and the footprint is larger.
Which Walsin array matches an automotive, 0402, 200 ppm, 10 kilohm brief?
None in the export. MA04X1002FTL matches series, size, value and tolerance but is 300 ppm, while WA04X1002FTL is 200 ppm but belongs to the general series. Confirm against the datasheet and qualify in your own circuit.
Is a Walsin resistor array on the Hong Kong shelf?
One is, as at 23 September 2026: WA04X300 JTL, a general 0402 x 4 array. None of the 1,386 automotive array rows is stocked. The snapshot is dated, not live, so ask us through the site for a to-order enquiry.
Do you hold stock or an office in Romania?
No. We hold no office, entity or stock in Romania; our locations are Hong Kong, Shenzhen, Singapore and Jiangmen. We hold no ISO 9001 or IATF 16949 certificate and give no legal, customs or conformity advice. Confirm with your compliance team.
