Equivalent & Alternatives
The following parts are listed as comparable options for similar super red LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMR335U1V2-GS08 | Higher luminous intensity (450–1120 mcd), red (619–631 nm) rather than super red; same PLCC-2 package and 20 mA test condition | Better suited for high-brightness signaling where wider spectral tolerance is acceptable; not color-matched to VLMS335T1U2-GS08's 626–639 nm band | Select when higher output is prioritized over strict super red chromaticity - verify optical filter compatibility in color-critical systems |
| VLMY335U1V2-GS08 | Yellow emission (583–594 nm), similar intensity range (450–1120 mcd), same package and drive conditions but different semiconductor bandgap | Used where amber/yellow coding is required for warning states; incompatible for red-specific applications like stop lights or error alerts | Choose only for yellow-coded status indication; cannot substitute in red-designated circuits without optical redesign |
Compared with VLMS335T1U2-GS08, VLMR335U1V2-GS08 offers higher brightness but broader red spectrum, while VLMY335U1V2-GS08 shifts output to yellow - neither provides identical super red chromaticity or T1/U2 binning, making them functional alternatives only in non-color-critical or multi-color indicator systems.
