Buyer and engineer answers

What must be established before ordering

Statements below are scoped to the named manufacturer source. Commercial availability is deliberately separate.

Technical answer

SOD-523 mechanical boundary

Use the selected manufacturer’s SOD-523 drawing and recommended land pattern. A smaller package name never proves it can occupy a SOD-323 footprint.

Power and current by brand

Power derating and current limits depend on the exact manufacturer record, PCB test condition and thermal environment; values are not merged across brands.

Packing and marking

Marking and reel suffix are order-code facts. The exact manufacturer and code must be confirmed before stock or price is attached.

Publication safeguard

The claim boundary travels with the page.

Never present a different package as PCB-compatible without comparing the exact mechanical drawing and land pattern.

Procurement FAQ

Questions this exact page answers

Compatibility answers remain conditional where the source evidence does not establish a direct replacement.

1N4148WT vs 1N4148WS package size?

They refer to different small-outline package families in the reviewed sources; compare both mechanical drawings and land patterns.

Can SOD-523 fit a SOD-323 footprint?

Do not assume it. Validate pad geometry, solder fillets, assembly process and polarity using the manufacturer drawings.

Which brand is in stock?

Brand, exact ordering suffix, quantity, date code and availability are confirmed only in the current quotation.
