Substitute Part Grouping Explanation

Substitution of the LS Y876-Q1R2-1 is based on strict electrical and mechanical parameter alignment within the Micro SIDELED® 3010 series. The substitute part LS Y876-P2S1-1-Z maintains identical specifications across all critical parameters: dominant wavelength (633nm), peak wavelength (645nm), forward voltage (2V), test current (20mA), viewing angle (120°), lens dimensions (1.70mm x 0.70mm), mounting type (surface mount, right angle), package configuration (2-SMD flat lead), physical dimensions (2.20mm L x 1.20mm W), and maximum height (1.20mm).

The primary distinction between these parts is product status and packaging format. The LS Y876-Q1R2-1 is obsolete with limited inventory (651 pieces), while the LS Y876-P2S1-1-Z is active with significantly higher availability (10,608 pieces). The substitute part features a higher millicandela rating (140mcd versus 125.5mcd), representing improved luminous intensity while maintaining all other electrical and mechanical specifications. Both components comply with ROHS3, maintain identical MSL ratings, and share the same base product number (LSY876).

Parameter Comparison

Engineering Selection Recommendations

The LS Y876-P2S1-1-Z is the direct active equivalent for the obsolete LS Y876-Q1R2-1. Selection of the substitute part is based on the following engineering criteria:

Product Status Alignment: The LS Y876-P2S1-1-Z maintains active product status, ensuring long-term supply chain viability and manufacturer support, whereas the LS Y876-Q1R2-1 is classified as obsolete with finite inventory.

Electrical Compatibility: Both components operate at identical forward voltage (2V) and test current (20mA), with matching wavelength specifications (633nm dominant, 645nm peak). The substitute part delivers enhanced luminous intensity (140mcd versus 125.5mcd) while maintaining all other electrical parameters.

Mechanical Compatibility: Identical mounting type (surface mount, right angle), package configuration (2-SMD flat lead), physical dimensions (2.20mm L x 1.20mm W, 1.20mm maximum height), and lens specifications (1.70mm x 0.70mm clear rectangular) ensure direct mechanical interchangeability.

Regulatory Compliance: Both components maintain ROHS3 compliance, identical MSL ratings (2, 1 Year), REACH unaffected status, and matching ECCN/HTSUS classifications, satisfying all regulatory requirements.

Packaging Consideration: The substitute part is supplied in Tape & Reel format, standard for production environments, whereas the main part is available in bulk packaging. This difference does not affect component functionality or performance.

Frequently Asked Questions (FAQ)

Q: Can the LS Y876-P2S1-1-Z directly replace the LS Y876-Q1R2-1 in existing designs?

A: Yes. The substitute part maintains identical electrical specifications (2V forward voltage, 20mA test current, 633nm dominant wavelength, 120° viewing angle) and mechanical specifications (surface mount right-angle mounting, 2-SMD flat lead package, 2.20mm x 1.20mm x 1.20mm dimensions). Direct substitution is supported without design modification.

Q: What is the significance of the higher millicandela rating in the substitute part?

A: The LS Y876-P2S1-1-Z provides 140mcd luminous intensity compared to 125.5mcd in the LS Y876-Q1R2-1. This represents approximately 11.5% increased brightness while maintaining all other electrical and mechanical parameters. Applications requiring the original brightness specification should account for this difference in optical design.

Q: Are there packaging differences between these parts?

A: Yes. The LS Y876-Q1R2-1 is supplied in bulk packaging, while the LS Y876-P2S1-1-Z is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and does not affect component performance or electrical characteristics.

Q: Why is the LS Y876-Q1R2-1 classified as obsolete?

A: The LS Y876-Q1R2-1 has been superseded by the LS Y876-P2S1-1-Z within the Micro SIDELED® 3010 series. The substitute part offers improved luminous intensity, active product status, and significantly higher inventory availability. Obsolete classification indicates the manufacturer no longer actively produces this variant.

Q: Do both parts comply with current regulatory standards?

A: Yes. Both the LS Y876-Q1R2-1 and LS Y876-P2S1-1-Z are ROHS3 compliant, REACH unaffected, and share identical MSL ratings (2, 1 Year). Both components carry the same ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Q: What is the inventory status for each part?

A: The LS Y876-Q1R2-1 has 651 pieces available as new original stock. The LS Y876-P2S1-1-Z has 10,608 pieces available as new original stock, providing substantially higher availability for production requirements.

Q: Are the lens specifications identical between these parts?

A: Yes. Both components feature identical lens specifications: colorless, clear transparency, rectangular shape with flat top, and 1.70mm x 0.70mm dimensions. Optical performance and viewing angle (120°) are identical.
