Resistor array Colombia buyers should check power before geometry: in Walsin’s export, 571 of the 693 four-element 0603 concave arrays are rated 1/16 W per element, while all 2,844 convex 0603 arrays are 1/10 W. A concave part is not a drop-in for a convex one at 1/10 W.
Venatech Limited, an authorised Walsin distributor in Hong Kong, holds the Walsin Technology (Walsin) chip resistor parametric exports: 137 files, 234,815 rows, of which 10,120 are arrays or networks. This post is for a buyer or design engineer at a Colombian appliance or electronics assembler whose bill of materials lists a four-element 0603 array and who wants the differences stated. Every part number below is real, every count is ours, and the one development cited is dated and sourced (fetched 2 November 2026).
What did Colombia’s statistics office report about imports?
Imports of manufactures rose strongly. DANE’s import statistics show August 2026 imports of about 7.7 billion US dollars on a CIF basis, up 31.7 percent on August 2025, and DANE attributes the growth mainly to an 18.9 percent rise in the manufactures group. The page was marked as updated on 21 October 2026.
The page does not say which manufactures, whether electronic components moved with them, or who bought them, and we draw no conclusion about any Colombian company. We have no relationship with DANE.

Is a Walsin concave array the same power as a convex array?
No, and the difference is large. We parsed all 3,537 four-element 0603 array rows: the 2,844 convex parts are rated 1/10 W at every tolerance, but the 693 concave parts split, with 571 plus or minus 1 percent parts at 1/16 W and 121 plus or minus 5 percent parts at 1/10 W. One 0 ohm jumper row also reads 1/10 W. We have not seen this split counted anywhere.
At 0402 the picture is flatter: all 497 plus or minus 5 percent and 2,284 plus or minus 1 percent convex parts read 1/16 W, and so do the 269 concave rows. Across all 10,120 array and network rows, none is a 0603 concave at 1 percent that reaches 1/10 W. As at 23 September 2026 our shelf holds one array line, WA04X300JTL, an 0402 convex 30 ohm part at plus or minus 5 percent.
| Group (four elements, 0603) | Parts | Rated power in export | Tolerance |
|---|---|---|---|
| Convex, all series | 2,844 | 1/10 W | 1% (2,284), 5% (556), jumper (4) |
| Concave | 571 | 1/16 W | 1% |
| Concave | 121 | 1/10 W | 5% |
| Concave | 1 | 1/10 W | jumper |
Which part numbers answer a 10 ohm, 1 percent, 1/10 W four-element 0603 requirement?
Four of six answer it, and the two that do not differ in power or size. The export lists one 10 ohm, 1 percent part per series, and only the concave one drops to 1/16 W. The last column is for your incumbent part.
| Walsin part | Configuration, value, tolerance, TCR, power per element | Match / mismatch against the requirement | Your incumbent |
|---|---|---|---|
WA06X10R0FTL |
0603 x4 convex, 10 ohm, 1%, 100 ppm, 1/10 W | Match on value, tolerance, power; TCR is the tightest of the set | |
WA06X10R0FTLJ |
0603 x4 convex, 10 ohm, 1%, 200 ppm, 1/10 W | Match on value, tolerance, power; mismatch on TCR against its non-J twin; J is unexplained | |
SA06X10R0FTL |
0603 x4 convex anti-sulfuration, 10 ohm, 1%, 200 ppm, 1/10 W | Match on value, tolerance, power | |
MA06X10R0FTL |
0603 x4 convex, series marked automotive, 10 ohm, 1%, 200 ppm, 1/10 W | Match on value, tolerance, power; the label is Walsin’s, we make no qualification claim | |
WA06T10R0FTL |
0603 x4 concave, 10 ohm, 1%, 200 ppm, 1/16 W | Mismatch on power: 1/16 W, not 1/10 W | |
WA04X10R0FTL |
0402 x4 convex, 10 ohm, 1%, 200 ppm, 1/16 W | Mismatch on size and power |
What will we not tell you about Colombia?
Anything about Colombian customs, certification or procurement rules. We hold no office, entity or stock in Colombia; our locations are Hong Kong, Shenzhen, Singapore and Jiangmen, with Chengdu in preparation. We state no duty rate, transit time, carrier or conformity requirement, and we give no legal or customs advice; confirm with your compliance team.
Why buyers in Colombia choose Venatech
Buyers in Colombia write to us for four reasons we can show rather than claim. First, Venatech Limited is an authorised Walsin Technology distributor in Hong Kong; confirm that with Walsin. Second, small lots are welcome, and the service is run from Hong Kong, so a prototype quantity is a normal request, not an exception. Third, the free VenaMatch cross-reference tool decodes 18 manufacturers’ part numbers and covers 800,000+ crossable parts, and it prints the mismatches next to the matches. We will not tell you a part is a drop-in. We will show you where it differs. Fourth, we say what we do not hold. The array series has no datasheet in our 28, and the export names no package power, so we flag it above rather than imply coverage. We make no price, lead-time or stock promise in a post; the ready-stock list is a dated snapshot and the quote route on the site is where availability is confirmed. Our one named third-party credential is UL file E182369, which covers our safety capacitor series, not the parts in this post, and you can look it up in UL’s public database.
How Venatech helps
Paste the incumbent part number 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 the list to the BOM checker, up to 500 part numbers. The Hong Kong ready-stock list is a dated snapshot, 23 September 2026, never 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 chip resistor range lists the families, our post on chip resistor arrays explains convex and concave, and power rating by case size explains the watt steps. Qualification stays with you.
The short version
Check power per element before geometry. Walsin’s 0603 four-element arrays are 1/10 W in all 2,844 convex parts, but 571 of the 693 concave parts are 1/16 W. One array line is on our 23 September 2026 shelf, an 0402 convex part.
Send us one array line from your bill of materials and we will return the Walsin parts with every difference stated. Is your array convex or concave, and what power does each element see?

What did DANE report about Colombian imports in August 2026?
Imports were about 7.7 billion US dollars CIF, up 31.7 percent on August 2025, with DANE pointing mainly to an 18.9 percent rise in manufactures. The page, updated 21 October 2026, does not name components, and we draw no conclusion about any firm.
How many Walsin resistor array rows are in your export?
10,120 array and network rows, of which 3,537 are four-element 0603 arrays. Of those, 2,844 are convex and 693 concave. We hold no datasheet for them, so power and TCR come from the export alone.
Are concave and convex 0603 arrays the same power?
No. All 2,844 convex four-element 0603 parts read 1/10 W. Of the 693 concave parts, 571 at plus or minus 1 percent read 1/16 W and 121 at plus or minus 5 percent read 1/10 W. Check the tolerance and shape together.
Is any Walsin array on your shelf?
As at 23 September 2026 one array line, WA04X300JTL, an 0402 convex 30 ohm part at plus or minus 5 percent. The parametric export spells it with a space, which is why a naive paste can miss it. Stock is a snapshot, not a promise.
What does the J suffix on an array part mean?
The export does not say. WA06X10R0FTL lists 100 ppm and WA06X10R0FTLJ lists 200 ppm for the same value, tolerance and power. Treat them as two parts and confirm the difference with Walsin before crossing.
Do you ship to Colombia?
We ship from Hong Kong and state no duty, customs, certification or transit information for Colombia. We hold no office or stock there and give no legal or customs advice; confirm with your compliance team. You can request a quote through the site.
