Parameter Comparison

Engineering Selection Recommendations

Both LTST-C170JRKT and LTST-C170KRKT are active production components from Lite-On Inc. with identical electrical and mechanical specifications for core LED parameters. Both parts comply with REACH regulations and carry ECCN EAR99 classification.

The LTST-C170KRKT offers higher millicandela rating (54mcd versus 30mcd) and improved lens design (Rectangle with Flat Top), providing enhanced brightness and optical performance while maintaining full electrical compatibility. Both parts share identical forward voltage, test current, wavelength characteristics, and physical dimensions.

Selection between these parts depends on brightness requirements for the specific application. The substitute part provides superior luminous intensity without compromising compatibility.

Frequently Asked Questions (FAQ)

Q: Can LTST-C170KRKT replace LTST-C170JRKT in existing designs?
