A Philippine broadband or CPE builder crossing an RF chip inductor to Walsin should expect two names for one part. Walsin’s MCI, WLCM and WQCM families list 1,086 rows but only 558 distinct electrical rows, and 500 of them carry both an MCI and a WLCM part number with identical export fields. None of the 1,086 rows is on our 23 September 2026 shelf.
Venatech Limited, an authorised Walsin distributor in Hong Kong, holds the Walsin Technology (Walsin) inductor parametric export: 5,411 rows, 5,410 real part numbers once a QA test row is removed. This post is for a procurement or design engineer at a Philippine electronics manufacturer or network equipment builder whose boards carry RF matching inductors at 0603, 1005 and 1608 and who wants Walsin candidates with every difference stated. Every Walsin part number below is real, every count is ours, and the one news fact is dated and sourced (fetched 2 November 2026).
What did Converge say about its network rollout?
Philstar reported on 27 October 2026 that Converge may fall short of its 18 billion peso capital expenditure target for 2026, citing construction and network rollout delays. Earlier in the year the company had cut capex guidance from a range of 18 to 23 billion pesos to 17 to 20 billion, and cut revenue growth guidance from 8 to 10 percent to 4 to 6 percent. It spent 6.9 billion pesos in the first half.
The article says the company reports third-quarter 2026 results on 9 November and is expanding into the Visayas and Mindanao. It does not mention towers, poles, equipment suppliers or components, and we draw no conclusion about what any Philippine operator buys. We have no relationship with Converge or the newspaper.

How many Walsin RF inductor rows are really the same part under two or three names?
We parsed all 1,086 rows of the MCI (501), WLCM (559) and WQCM (26) families. They collapse to 558 distinct electrical rows, 474 of which carry an MCI and a WLCM name, and another 26 of which carry those two plus a WQCM name. We grouped on size, thickness, inductance, tolerance, Q minimum, self-resonant frequency, DC resistance and rated current, with currents and resistances normalised.
Only 58 rows are WLCM alone and none is MCI alone. So 500 of 558 electrical rows can be found under an MCI and a WLCM name, and 26 of those under a third. The 500 span three sizes: 348 at 0603, 119 at 1005 and 7 at 1608 for the two-name rows. We have not seen this counted anywhere. Note that the same inductance can sit in two electrical rows that differ in Q and resonant frequency, as the first two lines below show.
| Size and fields | Names for the one row | Match / mismatch |
|---|---|---|
| 0603, 0.3 nH plus or minus 0.1 nH, Q 11, SRF 18,000 MHz, 0.07 ohm, 850 mA | MCI0603TG0N3BHBP, WLCM0603TGB0N3TB |
Match on all export fields across two names |
| 0603, 0.3 nH plus or minus 0.1 nH, Q 4, SRF 10,000 MHz, 0.07 ohm, 850 mA | MCI0603HQ0N3BHBP, WLCM0603Z0B0N3TB |
Match across two names; mismatch with the row above on Q and resonant frequency |
| 1005, 0.3 nH plus or minus 0.1 nH, 0.08 ohm, 1 A | MCI1005HQ0N3BHBP, WLCM1005Z0B0N3TB |
Match across two names; mismatch with the 0603 rows on size and current |
| 1608, 150 nH plus or minus 5 percent, 1.2 ohm, 300 mA | MCI1608HQR15JHBP, WLCM1608Z2JR15TB |
Match across two names |
| 1608, 1 nH plus or minus 0.3 nH, 0.05 ohm, 1 A | MCI1608HQ1N0SHBP, WLCM1608Z2S1N0TB, WQCM1608A0S1N0TB |
Match across three names |
| 0603, 0.3 nH plus or minus 0.2 nH | WLCM0603Z0C0N3TB |
Mismatch: a WLCM-only row; the 0.2 nH tolerance has no MCI name |
Your incumbent part goes in a seventh column on your own copy; we do not name one.
What does the export not tell you about these inductors?
The export prints 8 fields per RF inductor and the names agree on all 8, but 0 of our 28 datasheets cover an inductor. We hold no Walsin datasheet for the MCI, WLCM or WQCM families, so we cannot state a temperature range, a packaging quantity, a Q test frequency or an inductance-versus-frequency curve for any name.
The 58 WLCM-only rows are mostly tolerance variants: they carry plus or minus 2 percent (15), 0.2 nH (13), 0.3 nH (13), 0.1 nH (10) and plus or minus 5 percent (7). Where a buyer’s incumbent is tightly toleranced, the WLCM-only rows are where a candidate may exist without an MCI twin. We do not say which name is preferred for new designs. The export carries a Q minimum but not the frequency at which it was measured.
Why buyers in Philippines choose Venatech
Buyers in the Philippines choose Venatech because we are an authorised Walsin Technology distributor working from Hong Kong, we supply small lots, and we show you every mismatch as well as the match. For this one RF inductor group we counted 1,086 rows down to 558 electrical rows and told you which 500 have two names. A buyer writing an approved vendor list can then name the electrical row, not just one of its names.
The VenaMatch cross-reference tool decodes 18 manufacturers’ part numbers and covers 800,000+ crossable parts, with every difference from your original stated. The BOM page takes up to 500 part numbers. We say what we do not hold: we hold neither ISO 9001 nor IATF 16949, and we hold no inductor datasheets. Lot and date-code traceability and a certificate of conformity per shipment are available on request. Ask, and we will tell you plainly what we can and cannot supply.
What will we not tell you about the Philippines?
Anything about Philippine customs, certification or import rules, or about telecom type approval. We hold no office, entity or stock in the Philippines; our locations are Hong Kong, Shenzhen, Singapore and Jiangmen, with Chengdu in preparation. We state no duty rate, transit time or conformity requirement and give no legal or customs advice; confirm with your compliance team. We also make no statement about Converge’s suppliers or its rollout.
How Venatech helps
Paste the incumbent inductor 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; it holds none of the 1,086 rows above. 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 export: MCI1005HQ0N3BHBP and WLCM1005Z0B0N3TB agree on 0.3 nH, 0.08 ohm and 1 A. Our post on multilayer versus wirewound inductors covers the families, rated current versus saturation current explains the current fields, and the inductor range lists them. Qualification stays with you.
The short version
Count the names before you count the parts. Walsin’s MCI, WLCM and WQCM RF inductor families are 558 electrical rows, not 1,086, and 500 of them carry both an MCI and a WLCM part number with identical export fields. None is on the 23 September 2026 shelf. Confirm against the datasheet and qualify in your own matching network.
Send us one RF inductor line from your bill of materials and we will return the Walsin candidates with every difference stated. Does your approved vendor list name the part by one prefix or by its electrical row?

Frequently asked questions
What did Converge report about its capex?
Philstar reported on 27 October 2026 that Converge may miss its 18 billion peso capital expenditure target for 2026 because of construction and network rollout delays. Guidance had already been cut to 17 to 20 billion pesos. The article names no components or suppliers.
How many Walsin RF inductor rows are duplicates?
Of 1,086 rows in the MCI, WLCM and WQCM families, 558 are distinct electrical rows. Four hundred and seventy-four carry an MCI and a WLCM name, another 26 carry those two plus a WQCM name, and 58 are WLCM only.
Do the two names for one row differ in any export field?
No. Size, thickness, inductance, tolerance, Q minimum, resonant frequency, DC resistance and rated current agree across the names after unit normalisation. The prefix and suffix differ, and we hold no datasheet to say whether packaging or test conditions differ.
Why can two 0.3 nanohenry 0603 rows both exist?
They differ in Q and resonant frequency: one prints Q 11 and 18,000 MHz, the other Q 4 and 10,000 MHz, with the same 0.07 ohm and 850 mA. Match the electrical row, not just the inductance.
Are any of these RF inductors on your shelf?
None of the 1,086 rows is on our 23 September 2026 Hong Kong ready-stock snapshot, which is dated and not live. Check the ready-stock page, or ask us to quote a lot, which we can do in small quantities from Hong Kong.
Do you ship to the Philippines or state its import rules?
We ship from Hong Kong and state no duty, customs, certification or transit information for the Philippines. 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.
