A Nepal EV importer or repair shop crossing an automotive-series ferrite bead to Walsin should count names. Walsin’s MCB and MHC Automotive series list 150 rows but only 79 distinct electrical rows: 66 pairs differ only by one suffix letter, H or Z, and 5 more rows also carry an MHC-S name. None is on our 23 September 2026 shelf.
Venatech Limited, an authorised Walsin distributor in Hong Kong, holds the Walsin Technology (Walsin) inductor and ferrite bead parametric export, file Walsin_Inductor_ALL.xlsx: 5,411 rows, 5,410 real part numbers once a QA test row is removed. This post is for a procurement or design engineer or service buyer in Nepal who wants Walsin candidates for an automotive-series ferrite bead 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 happened at the Rasuwagadhi crossing, and what does it carry?
The Kathmandu Post reported on 30 October 2026 that floods on 26 August cut off the Rasuwagadhi crossing with China again, and that electric vehicles make up 60 percent of imports through it, according to customs data. The crossing had reopened on 1 January 2026 after nearly six months closed. Other imports include electrical equipment, telecom equipment, hydropower machinery and industrial machinery.
Neither the Department of Customs nor the Department of Roads has given a firm reopening date. A Bailey bridge was expected before Tihar in early November, and four more are needed. The report names no component, no importer and no parts content of the vehicles, and we draw no conclusion about any Nepali company. We have no relationship with the newspaper.

How many Walsin automotive-series bead rows are really the same part under two or three names?
We parsed all 221 rows of the MCB / MHC Automotive series (150) and the MHC-S series (71) in Walsin_Inductor_ALL.xlsx. The 150 automotive rows collapse to 79 electrical rows: 66 carry two names, 5 carry three and 8 carry one. We grouped on size, thickness, impedance at 100 MHz, DC resistance, rated current and tolerance, with currents and resistances normalised.
The 66 pairs differ only by one letter in the suffix, H or Z, as in MHC1005S600PHP and MHC1005S600PZP. We have not seen this counted anywhere. The 5 three-name rows add an MHC-S name ending BP, and the other 66 MHC-S rows have no automotive twin. The 150 rows run across seven sizes, from 1005 to 4532, and are plus or minus 25 percent throughout.
| Size and fields | Names for the one row | Match / mismatch |
|---|---|---|
| 1005, 60 ohm, 0.06 ohm, 1.1 A | MHC1005S600PHP, MHC1005S600PZP |
Match on all export fields across two names |
| 1005, 60 ohm, 0.07 ohm, 2.5 A | MHC1005S600PBP |
Mismatch with the row above: same impedance, higher current; an MHC-S name with no automotive twin |
| 1005, 70 ohm, 0.15 ohm, 600 mA | MCB1005S700IHP, MCB1005S700IZP |
Match across two names |
| 1608, 470 ohm, 0.20 ohm, 1 A | MHC1608S471LBP, MHC1608S471LHP, MHC1608S471LZP |
Match across three names, one of them MHC-S |
| 1608, 1,000 ohm, 0.25 ohm, 800 mA | MHC1608S102ZBPA80, MHC1608S102ZHP, MHC1608S102ZZP |
Match across three names; the BP name carries an extra A80 tail |
Your incumbent part goes in a fifth column on your own copy; we do not name one.
What does the export not tell you about these beads?
The export prints 6 fields per bead and the names agree on all 6 for 71 automotive rows, but 0 of our 28 datasheets cover a ferrite bead, and the export has no qualification column. We hold no Walsin datasheet for the MCB, MHC or MHC-S families, so we cannot say what the H and Z suffix letters mean, whether the two share a qualification, or what a temperature range or packaging quantity is.
The series is named Automotive, which is a label in the export and not evidence of a test. We make no AEC-Q200 claim for any ferrite bead. A service buyer replacing a bead on an imported vehicle should ask Walsin for the documents for the exact part number and compare the incumbent’s own sheet. We do not guess, and none of the 221 rows is on our shelf.
Why buyers in Nepal choose Venatech
Buyers in Nepal 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 bead family we counted 150 rows down to 79 electrical rows, found the 66 pairs that differ by one letter, and said plainly what the export cannot tell you. That is useful to a buyer who needs a small quantity and a clear question for the manufacturer.
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 bead datasheets or qualification reports. 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 Nepal?
Anything about Nepali customs, certification, border logistics or EV import rules. We hold no office, entity or stock in Nepal; our locations are Hong Kong, Shenzhen, Singapore and Jiangmen, with Chengdu in preparation. We state no duty rate, transit time or conformity requirement, give no legal or customs advice, and make no statement about when the Rasuwagadhi crossing will reopen; confirm with your compliance team. We also make no statement about any vehicle’s parts.
How Venatech helps
Paste the incumbent bead 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 221 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: MHC1005S600PHP and MHC1005S600PZP agree on 60 ohm, 0.06 ohm and 1.1 A. Our post on what AEC-Q200 actually certifies explains why a series name is not proof, multilayer versus wirewound inductors covers the families, and the inductor range lists them. Qualification stays with you.
The short version
Count the names before you count the parts. Walsin’s MCB and MHC Automotive series are 79 electrical rows, not 150, and 66 pairs differ only by an H or Z in the suffix. The export has no qualification column and none of the 221 rows is on the 23 September 2026 shelf. Ask Walsin for the documents for the exact part number and qualify in your own vehicle.
Send us one ferrite bead line from your vehicle bill of materials and we will return the Walsin candidates with every difference stated. What does your incumbent’s H or Z actually mean?

Frequently asked questions
What did the Kathmandu Post report about Rasuwagadhi?
On 30 October 2026 it reported that floods on 26 August cut off the Rasuwagadhi crossing with China, that EVs make up 60 percent of imports through it per customs data, and that no firm reopening date has been given. It names no components.
How many Walsin automotive bead rows are duplicates?
Of 150 rows in the MCB / MHC Automotive series, 79 are distinct electrical rows: 66 carry two part numbers, 5 carry three including an MHC-S name, and 8 carry one. All are plus or minus 25 percent.
What do the H and Z suffix letters mean?
We do not know. The pairs differ only by one letter and agree on every export field, and we hold no Walsin datasheet for these families. Ask Walsin what the letters distinguish, such as packaging or a test release, before you rely on either.
Does the export say the automotive series is qualified?
No. The export has no qualification column. The series name says Automotive, but we make no AEC-Q200 claim for ferrite beads. Request the qualification documents for the exact part number from Walsin.
Are any of these beads on your shelf?
None of the 221 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 Nepal or state its import rules?
We ship from Hong Kong and state no duty, customs, certification or transit information for Nepal. 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.
