Equivalent & Alternatives
The following parts are listed as comparable options for similar red LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LST676-R1S1 | Same optical/electrical specs; Osram-branded equivalent with identical PLCC-2 footprint and binning | No functional difference; used interchangeably in automotive and telecom designs per Vishay cross-reference table | Select LST676-R1S1 when dual-sourcing with Osram-approved supply chain or existing Osram design-in |
| VLMK31R1S2-GS08 | Higher max luminous intensity (280 mcd vs. 224 mcd); same R1/S2 binning group but wider intensity spread | Suitable where higher brightness margin is required, but may require recalibration of current-limiting resistors | Choose VLMK31R1S2-GS08 only if system-level brightness validation confirms headroom beyond VLMK31R1S1-GS08's 224 mcd maximum |
Compared with LST676-R1S1, the VLMK31R1S1-GS08 offers identical performance and form factor under Vishay's manufacturing control; versus VLMK31R1S2-GS08, it provides tighter luminous intensity consistency (224 mcd max vs. 280 mcd) for applications requiring precise brightness matching across units.
