Is there a pin-compatible replacement for LTST-C171KGKT?

No pin-compatible replacements were identified in this review. A compatible part must match the 0603 package dimensions and land pattern exactly. Candidates reviewed had different package sizes or functions.

What risks should I check before replacing LTST-C171KGKT?

Before replacing LTST-C171KGKT, check three key risks: 1) Package mismatch, which requires PCB redesign. 2) Electrical differences, such as lower forward current ratings. 3) Optical variations in brightness (mcd) and viewing angle.

LTST-C171KGKT Alternatives, Datasheet & Cross Reference | LITEON

Finding a substitute for the LTST-C171KGKT, a common 0603 green LED, requires matching its package, color wavelength, and electrical ratings. While many green LEDs exist, careful datasheet review is critical to avoid board redesign.

AI replacement insight

Package riskhigh

Most alternatives are in different packages (e.g., 0805), requiring new PCB layouts.

Electrical riskmedium

Substitutes may have lower current ratings or different brightness levels, affecting performance and reliability.

Sourcing risklow

0603 green LEDs are a common component type with many potential suppliers.

Can it be replaced directly?

No direct, drop-in replacement was found in this review. All suitable candidates must match the 0603 package, green color, and key electrical ratings.

Best replacement path

Search for green LEDs in a 0603 (1608 metric) package with a dominant wavelength near 571nm and a forward current rating of at least 30mA.

Main risk

The primary risk when substituting this LED is physical incompatibility due to package size differences, which requires a board redesign.

Recommended alternatives

A functional alternative green LED with similar color, but requires board redesign due to a larger package.
