Is there a pin-compatible replacement for LTST-C190KGKT?

Currently, no pin-to-pin compatible replacement has been verified. Alternatives like NCD2012C1 are functionally similar but differ in package size, preventing a direct drop-in.

What risks should I check before replacing LTST-C190KGKT?

Key risks include package mismatch, which requires PCB redesign. Also verify luminous intensity binning and forward voltage to ensure consistent brightness and drive current in your application.

AI replacement insight

Package riskhigh

Most alternatives are in different packages, requiring PCB redesign.

Electrical risklow

Key electrical parameters like forward voltage are common and easy to match.

Can it be replaced directly?

No direct drop-in replacement has been identified. The primary challenge is matching the 0603 package, green color (574nm), and brightness (18-71 mcd) simultaneously.

Best replacement path

Consider functional alternatives like NCD2012C1 if a PCB layout change is feasible. Otherwise, search for other 0603 green LEDs with a ~574nm wavelength.

Main risk

The main risk is physical incompatibility, as most functionally similar LEDs may come in different package sizes (e.g., 0805), requiring board-level changes.

Recommended alternatives

A functional alternative with similar color and brightness, but in a larger 0805 package requiring layout changes.
