For Guatemalan assemblers shipping into regional markets, the Walsin 0201 chip inductor case (0603 metric) holds 888 parts in three series. 108 of the 172 MCI-TM rows publish the same six data fields as a WLCM or MCI part, so the new series adds 64 distinct specifications, and none of the 888 is on our shelf.
Venatech Limited, an authorised Walsin distributor in Hong Kong, holds the Walsin Technology (Walsin) inductor export: 5,410 real rows once the QA test row is removed. This post is for a purchasing or design engineer at a Guatemalan assembler building small radio or sensor boards for export who is crossing a 0201 inductor and wants to know which Walsin parts are genuinely different. Every part number is real, every count is ours, and the development it cites names its source and the day we fetched it (2 November 2026).
What did Guatemala’s trade pattern look like in the first four months of 2026?
Concentrated in five markets, with the region first. La Hora reported on 18 June 2026 that Central America took 1,851 million US dollars of Guatemala’s exports in January to April 2026, 32.4 percent of the total, ahead of the United States at 1,838 million (32.2 percent), and that 66 percent of exports go to just five markets: the United States, El Salvador, Honduras, Nicaragua and Mexico. The article names slow border crossings among the obstacles.
The article does not mention electronic components, and we draw no conclusion about any Guatemalan company. We have no relationship with La Hora or the people it quotes.

How many Walsin 0201 inductors are really different from each other?
Fewer than the part count suggests. We filtered all 5,410 rows of Walsin_Inductor_ALL.xlsx to the 0603 (0201) case and counted 888: 367 WLCM, 349 MCI and 172 MCI-TM, all 0.3 mm thick. We then normalised the units (the MCI-TM rows write current as 0.85A where the others write 850mA, and DC resistance without the ohm sign) and compared inductance, tolerance, Q Min, SRF, DC resistance and rated current.
108 of the 172 MCI-TM rows match a WLCM or MCI part on all six fields; 64 do not. The 64 include all 37 of the plus or minus 0.3 nH rows, 26 of the percentage-tolerance rows (13 at 3 percent and 13 at 5 percent) and 1 plus or minus 0.2 nH row. The MCI-TM series spans 0.6 to 75 nH in 68 inductance values and five tolerances, and its rated current falls from 0.85 A at 0.6 nH to 0.1 A at 75 nH. We have not seen this counted anywhere.
| Series | Parts at 0603 (0201) | Inductance range | Rows matching another series on six fields |
|---|---|---|---|
| WLCM | 367 | 0.3 to 100 nH | not tested |
| MCI | 349 | 0.3 to 39 nH | not tested |
| MCI-TM | 172 | 0.6 to 75 nH | 108 of 172 |
None of the 888 is on the 23 September 2026 shelf.
Which worked part numbers show a repeat and which show a real difference?
Take a 2.2 nH, plus or minus 0.1 nH line. MCI0603TM2N2BHBP publishes Q Min 14, SRF 11000, 0.15 ohm and 0.6 A, exactly what WLCM0603TNB2N2TB publishes, while WLCM0603Z0B2N2TB publishes Q Min 4 and 450 mA. Same inductance and tolerance, Q Min 14 against 4, so the series letters carry the decision.
| Your requirement | Walsin candidate | Match / mismatch | On the 23 September 2026 shelf | Your incumbent |
|---|---|---|---|---|
| 2.2 nH, 0.1 nH, 0201, Q 14 | MCI0603TM2N2BHBP |
Match on value, tolerance, size, Q 14, 0.6 A | No | |
| 2.2 nH, 0.1 nH, 0201, Q 14 | WLCM0603TNB2N2TB |
Match on all six fields with the MCI-TM part; the series name differs | No | |
| 2.2 nH, 0.1 nH, 0201, Q 4 | WLCM0603Z0B2N2TB |
Match on value, tolerance, size; mismatch: Q Min 4 and 450 mA | No | |
| 10 nH, 5%, 0201 | MCI0603TM10NJHBP |
Match on value, tolerance, size; 0.25 A, Q 14 | No | |
| 10 nH, 5%, 0201 | WLCM0603TNJ10NTB |
Match on all six fields with the MCI-TM part | No | |
| 75 nH, 5%, 0201 | MCI0603TM75NJHBP |
Match on value, tolerance, size; Q 8, 0.1 A, SRF 1000 | No | |
| 100 nH, 5%, 0201 | WLCM0603Z0JR10TB |
Match on value and tolerance; mismatch: current reads 60 with no unit | No |
The export is also inconsistent with itself at 0.6 nH: MCI0603TM0N6CHBP reads plus or minus 0.2 nH, while MCI0603TN0N6CHBP and WLCM0603TNC0N6TB carry the same letter C and read plus or minus 0.1 nH. Confirm the tolerance letter with Walsin before you order.

Why buyers in Guatemala choose Venatech
Guatemalan assemblers buy small lots of small parts for boards that ship into a region concentrated on 5 markets, so 1 straight answer on what is really different saves 2 rounds of enquiries.
- The 0201 case has 888 Walsin parts, and we tell you that 108 of the 172 MCI-TM rows repeat another series’s six data fields before you order two part numbers for one specification.
- We flag the unit and letter inconsistencies we found, such as current written as 0.85A in one series and 850mA in another.
- Venatech Limited is an authorised Walsin Technology distributor in Hong Kong; confirm it with Walsin.
- We work from Hong Kong and welcome small lots, so a prototype run or a first production lot is a normal enquiry.
- VenaMatch, our free cross-reference tool, decodes 18 manufacturers’ part numbers and covers 800,000+ crossable parts, and it returns Walsin candidates with match and mismatch fields.
- We show the mismatches as well as the matches, because a cross that hides a difference is a scrapped board. That honesty is the product.
- The Hong Kong ready-stock list is a dated snapshot (23 September 2026), never live, so you see exactly what we claim and when.
- We hold 28 Walsin datasheets (26 MLCC, 2 chip resistor, 451 pages) and send the one covering your part number on request.
- We offer lot and date-code traceability, a certificate of conformity per shipment on request, and original sealed Walsin packaging.
- Our safety-capacitor documentation carries named third-party numbers you can check: UL file E182369 and TUV certificates R50381780 and R50195920.
We hold neither ISO 9001 nor IATF 16949, and we say so up front; qualification stays with you.
How Venatech helps
Paste your incumbent 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. Worked example from our exports: for a 2.2 nH, plus or minus 0.1 nH line at 0201 we show MCI0603TM2N2BHBP, WLCM0603TNB2N2TB and WLCM0603Z0B2N2TB side by side with Q and current differences stated. See also rated current vs saturation current, how to tell Walsin inductor series apart and the inductor range page. Qualification stays with you.
The short version
At 0201 Walsin lists 888 inductors in three series, 108 of the 172 MCI-TM rows repeat another series on six fields, and none is on the shelf.
Send us one 0201 inductor line from your bill of materials and we will return the Walsin candidates with every difference stated. Is Q or current the field that decides that line?

Frequently asked questions
What did La Hora report about Guatemala’s exports?
On 18 June 2026 La Hora reported Central America as Guatemala’s top destination for January to April 2026 at 1,851 million US dollars, 32.4 percent, ahead of the United States at 32.2 percent, with 66 percent of exports going to five markets. It does not mention electronic components.
How many Walsin inductors fit the 0201 case?
888 of the 5,410 inductor rows use the 0603 (0201) case: 367 WLCM, 349 MCI and 172 MCI-TM, all 0.3 mm thick. We counted them from the export. None is on our 23 September 2026 snapshot.
Are Walsin MCI-TM inductors different from WLCM and MCI?
Partly. 108 of the 172 MCI-TM rows publish the same inductance, tolerance, Q Min, SRF, DC resistance and rated current as a WLCM or MCI part, and 64 do not. Check the datasheet for the construction difference.
What Q does a Walsin 0201 inductor have?
Q Min in the export runs from 4 to 14 at 2.2 nH, depending on the series letter: HQ and Z0 rows publish 4, TG 12 and TN or TM 14. We hold no datasheet that states the test frequency, so confirm it with Walsin.
Is the 0.6 nH tolerance letter consistent?
No. MCI0603TM0N6CHBP reads plus or minus 0.2 nH, while MCI0603TN0N6CHBP and WLCM0603TNC0N6TB carry the same letter C and read plus or minus 0.1 nH. We flag it; confirm with Walsin.
Do you ship to Guatemala or state its import rules?
We ship from Hong Kong and state no duty, customs, certification or transit information for Guatemala. 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.
