Vishay CRCW to Walsin Cross-Reference for Malaysia: Walsin WR Power Sits One Step Below the CRCW Headline at 3 of 8 Sizes, and a 562 Ohm 0603 Brief Returns 23 Single Resistors at 4 Power Ratings, 0 on the Shelf

A Vishay CRCW to Walsin Technology (Walsin) cross-reference turns on rated power before anything else. At 0402, 0603 and 0805 the Walsin general purpose WR rating sits one step below CRCW’s headline figure, and the automotive MR series sits on it. For a 562 ohm, 1%, 0603 brief we found 23 single resistors at 4 power ratings, none on our shelf.

Venatech Limited, an authorised Walsin distributor in Hong Kong, holds the Walsin chip resistor export of 234,815 rows, 234,401 of them distinct part numbers once embedded spaces are removed, and a stock list dated 23 September 2026. This post is for a procurement or design engineer at a Malaysian electronics maker whose bill of materials names a Vishay CRCW resistor. Every Walsin part number is real and every count is ours. Statements from the press and from Vishay’s datasheet name their source and the day we read it, 23 October 2026.

What does Malaysia’s electronics output tell a resistor buyer?

That demand on the electrical and electronic side is rising fast. The Department of Statistics Malaysia reported, as covered by Malay Mail on 9 October 2026, that manufacturing sales were 185.0 billion ringgit in August 2026, up 9.9% on a year earlier, with electrical and electronic equipment sales up 22.6%. The same report says output of computer, electronic and optical products in export-oriented industries rose 24.9%, and sales for the first eight months of 2026 reached 1.39 trillion ringgit, up 7.9%.

We draw one conclusion, and it is ours: a buyer on a growing line is asked to hold more than one source for commodity resistors, and a cross-reference is the quickest way to start. We have no information on any maker’s Vishay volumes and say nothing about Vishay’s supply.

How do you read a Vishay CRCW part number, field by field?

In six fields. Vishay’s CRCW e3 datasheet, document 20035 and revision dated 14 April 2026, builds the global part number from a model, a size, a resistance, a tolerance letter, a temperature coefficient letter and a packaging code, and prints CRCW0603562RFKEA as its worked example. That is a 0603, 562 ohm, plus or minus 1%, plus or minus 100 ppm per kelvin part in packaging code EA.

All six Vishay fields map onto a Walsin field; the two Walsin elements with no CRCW field are the explicit termination letter T and an optional special-code suffix such as J, V or Z for automotive and anti-sulfuration variants. For the field-by-field Walsin layout, see our post on why Walsin part numbers do not paste into your BOM.

Where does Walsin’s rated power sit against the CRCW headline at each size?

One step lower at three sizes. Vishay prints a headline P70 of 0.10 W at 0402, 0.125 W at 0603 and 0.25 W at 0805, and a second table that gives standard and extended mode as 0.063/0.10, 0.10/0.125 and 0.125/0.25 W. The Walsin WR series rates the same three sizes at 1/16, 1/10 and 1/8 W, which are the standard figures, and the automotive MR series rates them 1/10, 1/8 and 1/4 W, which are the headline figures.

At the other five sizes the two makers agree. We took each Walsin figure from the Rated Power field of the export for 1 kilohm, plus or minus 1% parts with the FTL suffix.

We have not seen this three-sizes pattern counted anywhere. It means a drawing that says “0.125 W” on a 0603 is satisfied only by a part that is rated above the WR default, and that a downgrade from the MR figure is a design decision, not a typo. The MR series is the automotive one, so crossing a commercial CRCW to MR changes grade; grade up from commercial is a cost question, grade down is a qualification question. Our post on chip resistor power rating by case size covers the standard figures.

Which Walsin parts answer a CRCW0603 562 ohm, 1%, 100 ppm brief?

Twenty-three single resistors. In the Walsin export, 0603, 562 ohm, plus or minus 1% and 100 ppm or better returns 24 rows, one of them a four-element array, so 23 single resistors, in 14 series: 12 rated 1/10 W, 7 rated 1/8 W, 3 rated 1/3 W and 1 rated 1/4 W. None is on our stock list as at 23 September 2026.

A 0.125 W drawing is met on a commercial series by the High Power line, not the general purpose line. Six rows show the spread.

Packaging and the exact temperature coefficient letter stay open on every row, because the export does not print a reel quantity at this size. If your brief is 0.125 W and commercial, WF06P5620FTL is the row to compare first. Confirm against both datasheets and qualify in your own circuit.

What will we not tell you about a Vishay part?

Whether it is available, changing or constrained. We hold no Vishay affected-part list, we make no statement about any Vishay part number, and we hold no price or lead-time information on it. The CRCW sheet states AEC-Q200 qualification, Walsin’s MR sheet says compliant, and the two words are not the same claim; ask for the qualification report for the exact part number. Venatech makes no qualification claim of its own.

We hold no ISO 9001 or IATF 16949 certificate. Our locations are Hong Kong, Shenzhen, Singapore and Jiangmen, with Chengdu in preparation. We give no legal, customs or compliance advice; confirm with your compliance team.

How Venatech helps

Paste your CRCW number into the free cross-reference tool, which decodes 18 manufacturers’ part numbers across 800,000+ crossable parts, and read the Walsin candidates with each field marked match or mismatch. Load a whole BOM, up to 500 part numbers or an Excel or CSV file, to run every line at once. The ready-stock list is a Hong Kong snapshot dated 23 September 2026, and our chip resistor range lists the families.

Worked example from our own export: the 562 ohm brief above returned 24 rows and 23 single resistors, and the shelf covers none of them, while the 0603 general purpose line has 78 shelf part numbers across its 799 plus or minus 1% rows at other values. Walsin is the only line we are authorised for; Stackpole and Viking are lines we supply. We serve from Hong Kong in small lots, cross-reference your lines on request, and a quote is requested through the site.

The short version

For a Malaysian buyer holding a Vishay CRCW number, all six Vishay fields map to a Walsin number, but power does not map cleanly at 0402, 0603 and 0805: WR sits at the standard figure and MR at the headline. A 0.125 W commercial 0603 brief points to the High Power line.

Send us one CRCW line from your BOM, or paste it into the cross-reference tool, and we will return the Walsin candidates with power, grade and packaging differences stated. Qualification stays with you; which CRCW size do you run most?
