Is there a pin-compatible replacement for LTST-C170KGKT?

No pin-compatible replacement has been identified in this review. Candidates like NCD2012C1 are parametrically similar but have a different package size (0805 vs. 0603), preventing a drop-in replacement without PCB modification.

What risks should I check before replacing LTST-C170KGKT?

Key risks include package mismatch, as most alternatives may not be in the same 0603 footprint. Also, verify luminous intensity, viewing angle, and exact color wavelength (nm) to ensure consistent visual appearance in your application.

AI replacement insight

Package riskhigh

Target is 0603; candidates have different footprints requiring PCB changes.

Electrical risklow

Some candidates offer a very close match on voltage, current, and color.

Can it be replaced directly?

No direct, drop-in replacement for LTST-C170KGKT was found. All suitable candidates require some design modification, primarily for the package footprint.

Best replacement path

Use a parametrically similar LED like NCD2012C1, but requires verifying and possibly modifying the PCB footprint from 0603 to 0805.

Main risk

The primary risk is mechanical incompatibility due to different package sizes between the target and potential alternatives.

Recommended alternatives

Strong parametric match for a green LED, but comes in a larger package size that requires footprint verification.
