Procurement Notes
Verify the specific suffix TR9 against official Everlight documentation to confirm reel quantity and tape specifications. Ensure compatibility with standard reflow soldering profiles and moisture sensitivity level requirements during storage and handling procedures.
Selection Notes
Select this component when a low-profile red indicator with a Z-bend footprint is required. Compare electrical parameters such as forward voltage and luminous intensity against circuit constraints. Verify mechanical dimensions against PCB silkscreen and pad layout requirements before finalizing the design.
Part Context
This part belongs to the 91-21S series of single-color LEDs from Everlight. The series offers various color options and packaging styles including gull-wing and Z-bend configurations. The S530-A3 designation typically refers to the specific resin and lens characteristics for red emission variants within this product line.
Replacement Considerations
Cross-reference with other Everlight red LEDs in the 91-21S family sharing the same Z-bend package and electrical ratings. Verify pinout orientation and mechanical tolerance compatibility before substituting.
