Key Parameters

Substitute Part Grouping Explanation

Substitution for the SLR-332PC3FL is determined by the following critical parameters:

• Color: Green LED indication
• Package Type: Surface-mount (SMD) vs. Through-hole (T/H) mounting technology
• Functional Classification: LED Indication - Discrete
• Manufacturer: Rohm Semiconductor (same manufacturer preferred for consistency)

The identified substitute part RLI-343P8C3F shares the same manufacturer and functional classification but differs in mounting technology, transitioning from surface-mount to through-hole configuration. This substitution is valid when the application design permits mechanical and electrical accommodation of the alternative package type.

Parameter Comparison

Engineering Selection Recommendations

The RLI-343P8C3F is classified as an active product with confirmed inventory availability, making it a viable long-term alternative to the SLR-332PC3FL. Selection between these parts must be based on:

• PCB Design Compatibility: The SLR-332PC3FL requires surface-mount assembly processes and PCB pads designed for SMD footprints. The RLI-343P8C3F requires through-hole mounting with corresponding drilled vias and lead-compatible pad spacing.
• Manufacturing Process: Existing production lines configured for SMD assembly cannot directly accommodate through-hole components without process modification.
• Product Status Alignment: The RLI-343P8C3F's active status ensures continued availability and manufacturer support, whereas the SLR-332PC3FL's Last Time Buy status indicates limited future procurement windows.

Frequently Asked Questions (FAQ)

Q: Can the RLI-343P8C3F directly replace the SLR-332PC3FL on existing PCBs?

A: No. The SLR-332PC3FL is a surface-mount component, while the RLI-343P8C3F is a through-hole component. Direct PCB substitution requires design modification to accommodate the different mounting technology and footprint requirements.

Q: Are both parts manufactured by the same company?

A: Yes. Both the SLR-332PC3FL and RLI-343P8C3F are manufactured by Rohm Semiconductor, ensuring consistent quality standards and design philosophy across the product line.

Q: What is the significance of the SLR-332PC3FL's Last Time Buy status?

A: Last Time Buy status indicates that the manufacturer has set a final order deadline for this part. After this period, the component will no longer be available for purchase. Planning for alternative parts or securing sufficient inventory is recommended for long-term product support.

Q: Are there electrical performance differences between these parts?

A: The provided technical parameters do not include detailed electrical specifications such as forward voltage, luminous intensity, or current ratings. Verification of electrical compatibility requires consultation of the complete datasheets for both components.

Q: What inventory considerations should guide part selection?

A: The SLR-332PC3FL has 737 units in stock, while the RLI-343P8C3F has 802 units available. For new designs or long-term production, the RLI-343P8C3F's active status and higher inventory provide greater supply chain stability.
