Needs validationlow risk
A strong alternative with the same package and electrical ratings, but a slightly brighter, narrower viewing angle.
Best Alternatives to TSAL6400
TSAL6400 is a 940nm infrared emitting diode from Vishay in a T-1¾ package, notable for its wide ±25° viewing angle. When seeking replacements, it's crucial to match optical characteristics like radiant intensity and viewing angle.
AI replacement insight
Application riskhigh
Narrower viewing angle of substitutes may not provide required coverage.
Electrical risklow
Key voltage and current ratings are identical for top candidates.
Package risklow
Candidates share the same T-1¾ through-hole package.
Can it be replaced directly?
Direct replacement for TSAL6400 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Vishay's TSAL6200 is the most promising alternative, but requires validation of its narrower viewing angle for the specific application.
Main risk
Optical mismatch is the main risk. The narrower viewing angle of available alternatives could lead to reduced system performance or failure.
