For Australian buyers who want an authorised distributor to keep counterfeit components out, Venatech Limited, an authorised Walsin distributor in Hong Kong, lists 1,125 Walsin Technology (Walsin) part numbers in ready stock as at 23 September 2026: 864 MLCC, 254 chip resistors and 7 other parts, all sourced through our authorised Walsin channel.
Venatech Limited, an authorised Walsin distributor in Hong Kong, wrote this for procurement and quality staff in Australia’s defence, aerospace and high-reliability electronics sector, where a buyer under schedule pressure can end up in an unfamiliar channel. We counted our own ready-stock list as at 23 September 2026 and parsed Walsin’s MLCC export, 00_ALL_MLCC_parts_combined.xlsx, and our chip-resistor upload files. Every count below we re-measured on 11 November 2026.
What did Defence Connect report about counterfeit parts in defence supply chains?
That most nonconforming parts reported were suspect counterfeits. Defence Connect’s Land 2026 digital magazine, in an article contributed by component supplier Astute, cites ERAI’s 2025 annual report: 68.84 percent of nonconforming parts reported to ERAI were classified as suspect counterfeit, and almost a quarter of suspect counterfeit parts passed electrical testing.
The same article says more than a third of the reported parts were active components and 81.1 percent of the occurrences had not been reported to ERAI before. These figures describe parts reported to ERAI’s database, not the incidence across the whole market, and the article is company-contributed. Its advice is plain: use open-market sources only when authorised sources cannot meet the schedule, and choose suppliers before a requirement becomes urgent. We agree with that order of preference and make no other claim about the market.
Why are passive components part of the counterfeit problem?
Because they are cheap to fake and hard to test. The ERAI figures cited put active components at more than a third of reported parts and do not break down the rest, but an MLCC or chip resistor with the wrong dielectric or a relabelled reel can pass a quick functional test.
A 100 nF capacitor with a cheaper dielectric still measures 100 nF on a bench meter at room temperature; it fails later, hot or under bias. That is why the channel matters as much as the part number. Our guides to counterfeit passive components and authorised sourcing and what “authorised distributor” means and how to verify one explain the checks.
What does Venatech hold in Hong Kong ready stock?
1,125 Walsin part numbers. We counted our ready-stock list as at 23 September 2026: 1,125 distinct Walsin part numbers, of which 732 are general MLCC, 132 specialty MLCC, 254 chip resistors, 3 safety capacitors, 2 inductors, 1 resistor array and 1 high-voltage MLCC.
| Product line | Part numbers on the list | Examples |
|---|---|---|
| MLCC, general | 732 | 0402B104K500, 0603B104K500 |
| MLCC, specialty (RF 71, SH soft termination 33, HH high-Q 23, other 5) | 132 | SH18B104K500 |
| Chip resistors | 254 | WR06X1002FTL |
| Safety capacitors | 3 | S242B102K502 |
| Inductors | 2 | WLPH252012M2R2PP |
| Resistor array | 1 | WA04X300JTL |
| High-voltage MLCC | 1 | — |
| Total | 1,125 |
Every line on the list is a Walsin part, and Walsin is the line Venatech is authorised for. The ready-stock list is a Hong Kong snapshot dated 23 September 2026, not a live feed. Our MLCC range lists the families behind it.
How do common Australian defence BOM lines cross to stocked Walsin parts?
Most common values sit on the shelf. We checked five everyday lines from a typical control or radio board against the stock list as at 23 September 2026 and Walsin’s exports: all five cross to a Walsin part we hold in Hong Kong.
| BOM line (brief) | Walsin part | Held 23 Sep 2026 | Match / mismatch with the brief | Your current part |
|---|---|---|---|---|
| 0402, 100 nF, X7R, 50 V, ±10% | 0402B104K500 |
Yes | Match | |
| 0603, 100 nF, X7R, 50 V, ±10% | 0603B104K500 |
Yes | Match | |
| 0603, 100 nF, X7R, 50 V, flexible termination | SH18B104K500 |
Yes | Match, soft termination | |
| 0603, 10 kΩ, 1%, 1/10 W | WR06X1002FTL |
Yes | Match | |
| 0402, 30 Ω, 5%, four-element array | WA04X300JTL |
Yes | Match, convex array |
These are export-field matches. For defence work, confirm each line against the Walsin datasheet and your programme’s qualification rules. For any line not on the list, request a quote and we source it through our authorised Walsin channel rather than the open market.
What should an Australian buyer ask any passive-component supplier?
Three questions before price. We suggest every Australian buyer ask, in writing: is the supplier authorised by the manufacturer for this line, can it show the source of this lot, and will it name the manufacturer’s part number exactly as on the datasheet.
An authorised distributor can answer all three for its authorised lines. For lines a supplier merely “supplies”, ask the same questions and expect a different answer. Venatech is authorised for Walsin only; Stackpole and Viking are lines we supply. We give no legal, customs, export-control or certification advice; confirm with your compliance team.
How does Venatech help an Australian defence or high-reliability buyer?
How Venatech helps starts with your BOM. Venatech, Walsin’s authorised distributor in Hong Kong, runs VenaMatch, which decodes part numbers from 18 manufacturers and crosses 800,000+ parts to Walsin, so a BOM built on other brands can be moved onto an authorised Walsin channel line by line.
Paste up to 500 lines into the cross-reference tool or load a full BOM; each field is marked match or mismatch. The ready-stock list shows what we hold in Hong Kong as at 23 September 2026. We serve Australia from Hong Kong in small lots with fast quotes, and give no stock or delivery promise.
The short version
ERAI figures cited by Defence Connect show most nonconforming parts reported were suspect counterfeits, and many pass electrical tests. Buying passives through an authorised channel removes that question for the line: Venatech, Walsin’s authorised distributor in Hong Kong, holds 1,125 Walsin part numbers in ready stock.
Send us your passive BOM and we will return the Walsin matches, with the lines we hold in Hong Kong marked.

Frequently asked questions
What share of nonconforming parts reported to ERAI were suspect counterfeit?
Defence Connect’s Land 2026 magazine cites ERAI’s 2025 annual report: 68.84 percent of nonconforming parts reported to ERAI were classified as suspect counterfeit. The figure covers reported parts only, not the whole market.
Can passive components be counterfeited?
They can, and they are hard to catch: a capacitor with the wrong dielectric can pass a quick bench test. The cited ERAI figures put active components at more than a third of reported parts and do not break down the rest. Buying through an authorised channel for the line is the simplest control.

How many Walsin parts does Venatech hold in Hong Kong?
We counted 1,125 distinct Walsin part numbers on our ready-stock list as at 23 September 2026, including 864 MLCC and 254 chip resistors. The list is a dated snapshot, not live stock.
