Substitute Part Grouping Explanation

Substitution for the SLR-342PCTB7K is based on functional equivalence within the LED indication category. The primary substitute identified is the RLI-343P8CT32, also from Rohm Semiconductor. This substitution is valid based on the following criteria:

• Both components serve the LED indication function in discrete applications
• Both are manufactured by the same supplier, ensuring consistency in quality and reliability standards
• The substitute part maintains active product status, providing long-term availability and supply chain stability
• Functional compatibility is established through shared application category and manufacturer lineage

The key differentiator between the main part and substitute is the package type: the original uses SMD (Surface Mount Device) packaging, while the substitute uses T/H (Through-Hole) packaging. This distinction is critical for design implementation and PCB layout considerations.

Engineering Selection Recommendations

The RLI-343P8CT32 is the qualified substitute for the SLR-342PCTB7K based on manufacturer continuity and active product status. Selection between these parts depends on PCB assembly requirements:

• Use SLR-342PCTB7K for existing designs with SMD assembly processes and available inventory
• Use RLI-343P8CT32 for new designs requiring long-term supply assurance, as it maintains active status with Rohm Semiconductor
• Verify PCB layout compatibility with the package type transition (SMD to Through-Hole) before implementation

Frequently Asked Questions (FAQ)

Q: Can the RLI-343P8CT32 directly replace the SLR-342PCTB7K in existing assemblies?

A: Direct replacement depends on PCB design. The SLR-342PCTB7K uses SMD packaging while the RLI-343P8CT32 uses Through-Hole packaging. PCB footprints and assembly processes differ between these package types. Design modification is required for substitution.

Q: Why is the SLR-342PCTB7K marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has ended or will end production of this part number. Rohm Semiconductor recommends transitioning to active alternatives such as the RLI-343P8CT32 for future designs.

Q: Are both parts from the same manufacturer?

A: Yes, both the SLR-342PCTB7K and RLI-343P8CT32 are manufactured by Rohm Semiconductor, ensuring consistent quality standards and reliability characteristics.

Q: What is the primary difference between these two LED indicators?

A: The primary difference is packaging: SLR-342PCTB7K is surface-mount (SMD), while RLI-343P8CT32 is through-hole (T/H). This affects PCB layout, assembly method, and mechanical mounting approach.

Q: Is inventory availability a factor in part selection?

A: Both parts have adequate inventory. However, the RLI-343P8CT32 maintains active product status, providing better long-term supply chain assurance compared to the Last Time Buy status of the SLR-342PCTB7K.
