Substitute Part Grouping Explanation

Substitution for the SLR-342PC3FM is based on the following criteria:

• Color and Function: Green LED indicator capability
• Application Category: LED Indication - Discrete
• Manufacturer Alignment: Rohm Semiconductor recommended substitute
• Functional Equivalence: Direct replacement for indication purposes

The substitute part RLI-343P8C3F is identified as the manufacturer-recommended equivalent. While this part utilizes through-hole (T/H) packaging rather than surface-mount packaging, it maintains functional equivalence for LED indication applications and is sourced from the same manufacturer, ensuring design compatibility and supply continuity.

Engineering Selection Recommendations

The RLI-343P8C3F is the manufacturer-recommended substitute for the SLR-342PC3FM. Selection between these parts should be based on the following factors:

• Product Status: The SLR-342PC3FM is in Last Time Buy status. The RLI-343P8C3F is Active, providing long-term supply assurance for new designs.
• Packaging Compatibility: The SLR-342PC3FM is surface-mount, while the RLI-343P8C3F is through-hole. PCB layout and assembly process compatibility must be evaluated for your specific application.
• Functional Equivalence: Both parts provide green LED indication functionality from the same manufacturer, ensuring design compatibility.
• Inventory Availability: Both parts are currently in stock with adequate quantities for production requirements.

Frequently Asked Questions (FAQ)

Q: Can the RLI-343P8C3F directly replace the SLR-342PC3FM on existing PCBs?

A: Direct PCB replacement is not possible without layout modification. The SLR-342PC3FM is surface-mount, while the RLI-343P8C3F is through-hole. PCB footprints and assembly processes differ between these packaging types. Design changes are required for substitution.

Q: Why is the SLR-342PC3FM in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer has announced end-of-life production. Existing inventory (906 pcs) represents the final available stock. The RLI-343P8C3F is the recommended active alternative for future designs.

Q: Are both parts from the same manufacturer?

A: Yes, both the SLR-342PC3FM and RLI-343P8C3F are manufactured by Rohm Semiconductor, ensuring consistent quality and design compatibility.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on color (green), functional application (LED indication), manufacturer (Rohm Semiconductor), and discrete component classification. Packaging type (SMD vs. through-hole) is a design consideration rather than a functional limitation.
