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.
Manufacturer model / selection entry
1N4148WT is commonly associated with the miniature SOD-523 package; footprint, derating, electrical ratings, marking and order suffix remain manufacturer-specific.
Buyer and engineer answers
Statements below are scoped to the named manufacturer source. Commercial availability is deliberately separate.
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 derating and current limits depend on the exact manufacturer record, PCB test condition and thermal environment; values are not merged across brands.
Marking and reel suffix are order-code facts. The exact manufacturer and code must be confirmed before stock or price is attached.
Publication safeguard
Never present a different package as PCB-compatible without comparing the exact mechanical drawing and land pattern.
Procurement FAQ
Compatibility answers remain conditional where the source evidence does not establish a direct replacement.
They refer to different small-outline package families in the reviewed sources; compare both mechanical drawings and land patterns.
Do not assume it. Validate pad geometry, solder fillets, assembly process and polarity using the manufacturer drawings.
Brand, exact ordering suffix, quantity, date code and availability are confirmed only in the current quotation.
