Is there a pin-compatible replacement for TSAL6100?

Yes, Vishay's TSAL6200 and TSAL6400 are pin-compatible replacements. They use the same 2-pin T-1¾ (5mm) through-hole package. While they fit physically, their optical performance is different and requires review.

What risks should I check before replacing TSAL6100?

The main risk is reduced performance. Alternatives like TSAL6200 and TSAL6400 have significantly lower radiant intensity and a wider beam angle. You must verify that your system can tolerate a weaker, less focused IR signal, which could impact transmission distance and reliability.

TSAL6100 Alternatives, Datasheet & Cross Reference | VISHAY

Find alternatives for the Vishay TSAL6100, a high-power 940nm infrared emitter. While direct replacements are scarce, pin-compatible options from the same product family like the TSAL6200 exist but require careful review of their different optical characteristics.

AI replacement insight

Electrical riskhigh

Reduced radiant intensity will decrease the signal-to-noise ratio at the receiver, potentially causing system failure.

Package risklow

Candidates share the same T-1¾ package and pin count, ensuring mechanical and physical compatibility.

Sourcing risklow

All parts are from Vishay and appear to be active, simplifying procurement.

Can it be replaced directly?

No direct, drop-in replacement with identical performance was found. However, TSAL6200 and TSAL6400 are pin-compatible alternatives from the same product family with different optical characteristics.

Best replacement path

Use TSAL6200 for the closest parametric match, but you must validate if the lower radiant intensity (72 vs 170 mW/sr) is acceptable for your application's required range.

Main risk

The primary risk is a significant reduction in signal range and directivity due to the candidates' lower radiant intensity and wider viewing angles.

Recommended alternatives

Pin-compatible alternative from the same series, but with lower radiant intensity and a wider viewing angle.

Questions & answers

The best alternative is TSAL6200, which is in the same family and package. However, it has a lower radiant intensity (approx. 72 mW/sr vs 170 mW/sr) and a wider beam angle (±17° vs ±10°), which will reduce the effective range.
