Substitute Part Grouping Explanation

The VLRK31Q1R2-GS08 qualifies as a parametric equivalent to the VLRK31Q2R1-GS08 based on the following critical substitution criteria:

Matching electrical parameters: identical forward voltage (2.1V), test current (20mA), and wavelength specifications (630nm dominant, 643nm peak)

Matching mechanical parameters: identical lens configuration (round with flat top, 2.40mm diameter, clear transparency), mounting type (surface mount bottom entry), package type (2-SMD Z-Bend), and physical dimensions (3.20mm L x 2.80mm W, 2.10mm max height)

Matching compliance: both parts are ROHS3 compliant with identical moisture sensitivity level (2A, 4 Weeks)

The primary difference is product status: VLRK31Q1R2-GS08 is active with higher brightness rating (126mcd versus 115mcd) and available in Tape & Reel packaging, while VLRK31Q2R1-GS08 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The VLRK31Q1R2-GS08 is the direct active equivalent for the obsolete VLRK31Q2R1-GS08. Both parts share identical electrical and mechanical specifications, with the substitute offering higher brightness (126mcd versus 115mcd) at the same forward voltage and test current. The VLRK31Q1R2-GS08 maintains full ROHS3 compliance and identical moisture sensitivity classification.

Selection of VLRK31Q1R2-GS08 is appropriate for new designs and production continuity where the VLRK31Q2R1-GS08 is no longer available. The increased brightness rating of the substitute provides enhanced optical performance without requiring circuit modifications. Tape & Reel packaging of the substitute supports automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can VLRK31Q1R2-GS08 directly replace VLRK31Q2R1-GS08 in existing designs?
