The substitute part LG Y876-P1Q2-24-0-20-R18-Z maintains active product status and full mechanical and optical compatibility while differing in electrical operating parameters.

Parameter Comparison

Engineering Selection Recommendations

The LG Y876-P1Q2-24-0-20-R18-Z is the active equivalent substitute for the obsolete LT Y87S-P1Q2-35-Z. Both components are manufactured by ams-OSRAM USA INC. within the Micro SIDELED® 3010 series and maintain identical mechanical, optical, and regulatory compliance profiles.

The substitute part is available in active production status with significantly higher inventory availability (29,965 pieces in stock versus 890 pieces for the obsolete main part). Both components maintain ROHS3 compliance and identical Moisture Sensitivity Level ratings, ensuring regulatory continuity.

The primary design consideration is the difference in electrical operating parameters: the substitute operates at 2V forward voltage with a 20mA test current, compared to the main part's 3.4V at 10mA. Additionally, the dominant wavelength differs (570nm versus 528nm), representing a shift within the green spectrum. Circuit design modifications are required to accommodate these electrical differences.

Frequently Asked Questions (FAQ)

Q: Can the LG Y876-P1Q2-24-0-20-R18-Z be used as a direct drop-in replacement for the LT Y87S-P1Q2-35-Z?

A: The substitute part is mechanically and optically compatible, featuring identical mounting type, package configuration, physical dimensions, lens style, lens size, color, lens transparency, millicandela rating, and viewing angle. However, the electrical operating parameters differ (2V/20mA versus 3.4V/10mA), and the dominant wavelength differs (570nm versus 528nm). Circuit design modifications are required.

Q: What are the key mechanical compatibility factors?

A: Both components share identical specifications for mounting type (Surface Mount, Right Angle), package configuration (2-SMD, Flat Lead), physical dimensions (2.20mm L x 1.20mm W), maximum height (1.20mm), lens style (Rectangle with Flat Top), and lens size (1.70mm x 0.70mm). These parameters ensure PCB footprint and assembly compatibility.

Q: How do the optical characteristics compare?

A: Both components are green LEDs with clear, colorless lenses, identical millicandela ratings (78.5mcd), and identical viewing angles (120°). The dominant wavelength differs: the main part operates at 528nm while the substitute operates at 570nm. Both wavelengths fall within the green spectrum range.

Q: What packaging options are available?

A: The obsolete main part (LT Y87S-P1Q2-35-Z) is supplied in bulk packaging. The active substitute (LG Y876-P1Q2-24-0-20-R18-Z) is supplied in Tape & Reel (TR) packaging, which is standard for high-volume production environments.

Q: Are both components compliant with current regulatory standards?

A: Both components are ROHS3 compliant and REACH unaffected. Both maintain identical Moisture Sensitivity Level ratings (MSL 2, 1 Year). Regulatory compliance is maintained across the substitution.

Q: What is the inventory status difference?

A: The obsolete main part has 890 pieces in stock. The active substitute has 29,965 pieces in stock, providing significantly greater availability for ongoing procurement and production requirements.
