LED Indication - Discrete Procurement Notes

Verify the specific suffix designation against the manufacturer's latest datasheet to confirm optical and electrical tolerances. Ensure the procurement channel provides original documentation matching the 42-21A series specifications. Cross-reference the package dimensions with the 3224 metric standard to guarantee compatibility with existing PCB footprints and reflow soldering profiles.

LED Indication - Discrete Selection Notes

Select this component when high brightness is required for red indication within a compact 1209 package. The 25 mA forward current rating supports standard logic-level driving without excessive heat generation. Consider the 617.5–633.5 nm spectral range for optimal human eye sensitivity in ambient lighting conditions compared to longer wavelength alternatives.

LED Indication - Discrete Part Context

This part belongs to Everlight's discrete LED indication series, specifically engineered for surface-mount technology. The 42-21A prefix denotes a standard red LED variant optimized for general-purpose signaling. It complements other components in the same family that offer different colors or intensities while maintaining consistent mechanical dimensions for design flexibility.

LED Indication - Discrete Replacement Considerations

Direct substitutes must match the 1209 package, 633.5 nm peak wavelength, and 3600 mcd intensity. Verify pinout compatibility and forward voltage characteristics to ensure circuit performance remains unchanged during replacement.
