One 0402 chip resistor value shows how deep Walsin Technology (Walsin) goes for EMS lines in Vietnam: at 10 kilohm and 1 percent, Walsin lists 18 single resistors in 12 series, rated 1/16 W to 1/5 W. Venatech, Walsin’s authorised distributor in Hong Kong, crosses your incumbent to them free and holds 81 Walsin 0402 resistor lines.
Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this for an EMS sourcing or NPI engineer in the industrial parks of former Binh Duong province, which is now part of Ho Chi Minh City, who carries thousands of 0402 resistor lines across customer BOMs and wants fewer surprises when one of them has to be second-sourced. We parsed the 137 Walsin chip resistor export files and the 20 thin film files in our Walsin data folder (328,315 distinct part numbers) and our stock list as at 23 September 2026. We re-measured every count on 11 November 2026, and every part number below is real.
What did Tuoi Tre report about VSIP 4 Binh Duong?
A new industrial park of more than 750 hectares. According to Tuoi Tre News on 31 May 2026, Ho Chi Minh City approved the investment policy for Vinh Lap Industrial Park, also called VSIP 4 Binh Duong, covering more than 750 hectares, with over 497 hectares in a first phase worth more than 9.7 trillion dong, which the paper gives as about 369.2 million US dollars.
The park sits in Phu Giao Commune, formerly part of the Binh Duong province that has since merged into Ho Chi Minh City. The paper says it will prioritise high technology and advanced processing and manufacturing, with construction scheduled for 2026 to 2031, and that it brings Vietnam’s VSIP projects to 26 against a goal of 30. The article does not name electronics tenants, and we do not either. Our reading is simply that new high-technology floor space in the region means more SMT lines, and SMT lines run on 0402 passives.
How many Walsin 0402 chip resistors are there to choose from?
Tens of thousands. We counted 34,320 distinct Walsin part numbers in the 0402 (1005 metric) size across the chip resistor and thin film exports, 30,294 of them single resistors rather than arrays, networks or attenuators.
The single resistors cover general purpose thick film, automotive-labelled thick film, anti-sulfuration, high precision TC50 and TC100, high power, and power surge families. For an EMS buyer the point is coverage: when a customer BOM names a 0402 resistor from another maker, there is usually more than one Walsin family that can take the position, and the choice comes down to power, TCR and grade. The chip resistor range lists the families, and our guide to chip resistor power rating by case size explains why the same footprint can carry different ratings.
Which Walsin 0402 10 kilohm 1 percent resistors cross a 1/10 W brief?
Eight do. We filtered the 0402 rows to 10 kilohm at 1 percent and found 25 part numbers, 18 of them single resistors in 12 series; 8 are rated 1/10 W or more with a TCR of 100 ppm or better, the brief we set for a dense power-supply board.
The table shows those eight and two near misses. Put your incumbent in the last column.
| Walsin part | Family as the export names it | Rated power | TCR (ppm/K) | Match / mismatch with the brief | Your incumbent |
|---|---|---|---|---|---|
MR04X1002FTL |
General Purpose (Automotive) | 1/10 W | 100 | Match | |
SR04X1002FTL |
High Grade Anti-Sulfuration (Automotive) | 1/10 W | 100 | Match, adds anti-sulfuration | |
SR04X1002FTLW |
High Grade Anti-Sulfuration (Automotive) | 1/10 W | 100 | Match, packing variant | |
WF04P1002FTL |
High Power | 1/8 W | 100 | Match | |
WF04P1002FTR |
High Power LF 100ppm | 1/8 W | 100 | Match | |
SF04P1002FTP |
High Power (Anti-Sulfuration) | 1/8 W | 100 | Match | |
WF04A1002FTL |
High Power | 1/5 W | 100 | Match, highest power in the set | |
MF04E1002FTL |
Triple Power Surge (Automotive) | 1/5 W | 100 | Match, surge-rated | |
WR04X1002FTL |
General Purpose | 1/16 W | 100 | Mismatch: power is below the brief | |
WK04K1002FTL |
High Precision TC50 | 1/16 W | 50 | Mismatch: power below the brief, TCR better |
The other single resistors at this value are 1/16 W general purpose or TC50 parts, so if your board does not need the extra power, the list widens to all 18. A match here is a match on export fields. Confirm against Walsin’s own datasheets; we hold Walsin_WR_General_Purpose_Chip_Resistor.pdf and Walsin_MR_Automotive_Thick_Film_Chip_Resistor.pdf and send them on request.
Why does one resistor value appear in so many Walsin series?
Because the series differ in what they promise beyond resistance. Of the 18 single 10 kilohm 1 percent 0402 parts we counted, 10 are rated 1/16 W, 3 are 1/10 W, 3 are 1/8 W and 2 are 1/5 W, and 15 carry 100 ppm against 3 at 50 ppm.
For an EMS line this is useful twice. First, an incumbent from another maker can usually be crossed at the same footprint without dropping power or TCR. Second, the choice between general purpose, anti-sulfuration and automotive-labelled parts is a customer decision, not a sourcing shortcut: never move a customer’s automotive or industrial board to a commercial part without their written approval. Our page on what resistor TCR actually buys you covers the TCR side.
What does Venatech hold in Hong Kong in 0402 resistors?
81 Walsin 0402 resistor lines. Of the 1,125 distinct part numbers on our stock list as at 23 September 2026, 81 are Walsin resistors in the 0402 size.
That suits engineering builds and line-down cover for a Ho Chi Minh City EMS. For the 10 kilohm parts in the table, request a quote; we source them through our authorised Walsin channel. The ready-stock list is a dated snapshot, never live-synced, and we make no stock or lead-time promise.
What will we not tell you about your customers’ BOMs in Vietnam?
Whether a cross is approved for them. Our counts cover catalogue coverage only: 25 part numbers at 10 kilohm 1 percent in 0402, 18 single resistors, 8 inside a 1/10 W brief; none of it is a customer approval.
Your customer’s approved vendor list decides. We hold no office or entity in Vietnam; our locations are Hong Kong, Shenzhen, Singapore and Jiangmen, with Chengdu in preparation. We hold no ISO 9001 or IATF 16949 certificate and give no legal or customs advice; for import rules into Vietnam, confirm with your compliance team.
How Venatech helps: how fast can an EMS buyer in Ho Chi Minh City check a BOM?
One paste. Venatech is Walsin’s authorised distributor in Hong Kong, and VenaMatch decodes 18 manufacturers’ part numbers and crosses 800,000+ parts to Walsin, with every field marked match or mismatch.
Paste up to 500 part numbers into the free cross-reference tool, or drop an Excel or CSV BOM at /bom/ and request a quote. Filter by commercial or automotive grade. The ready-stock list is a Hong Kong snapshot dated 23 September 2026. Worked example from our own export: a 10 kilohm, 1 percent, 0402, 1/10 W brief returned 8 matches in 6 families. Walsin is the line we are authorised for; Stackpole and Viking are lines we supply. Small lots and fast quotes from Hong Kong.

Frequently asked questions
What is VSIP 4 Binh Duong in Vietnam?
Tuoi Tre News reported on 31 May 2026 that Ho Chi Minh City approved Vinh Lap Industrial Park, also called VSIP 4 Binh Duong, covering more than 750 hectares in Phu Giao Commune, formerly in Binh Duong province, with construction scheduled for 2026 to 2031. These are the paper’s figures, not ours.
How many Walsin 10 kilohm 1 percent 0402 resistors are there?
We counted 25 part numbers, 18 of them single resistors in 12 series, rated 1/16 W to 1/5 W. Eight are rated 1/10 W or more with 100 ppm TCR or better, including MR04X1002FTL, WF04P1002FTL and WF04A1002FTL.
Can I replace a 1/16 W 0402 resistor with a 1/5 W Walsin part?
On paper a higher rating at the same footprint gives margin, but confirm the TCR, the grade and the customer’s approval first. We show every difference from your original; we never call two parts interchangeable without your qualification.
Does Venatech stock 0402 chip resistors in Hong Kong?
Yes. As at 23 September 2026, 81 of the 1,125 part numbers on our snapshot are Walsin 0402 resistors. For other lines, request a quote and we source them through our authorised Walsin channel; we give no stock or lead-time promise.
Is Venatech an authorised Walsin distributor?
Yes. Venatech Limited is Walsin’s authorised distributor in Hong Kong. Stackpole and Viking are lines we supply.
Do you have an office in Vietnam?
No. We serve Vietnam from Hong Kong; our locations are Hong Kong, Shenzhen, Singapore and Jiangmen, with Chengdu in preparation. For Vietnamese import rules, confirm with your compliance team.
