Substitute Part Grouping Explanation

Substitution for the SLR-342PCTF7K 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 same functional purpose: LED indication in discrete applications
• Both are manufactured by the same original equipment manufacturer (Rohm Semiconductor), ensuring design consistency and quality standards
• The substitute part maintains active product status, providing long-term supply availability
• Functional compatibility is established through shared application category and manufacturer lineage

The key differentiator is the form factor: the SLR-342PCTF7K is surface-mount (SMD), while the RLI-343P8CT32 is through-hole (T/H). This distinction requires circuit board design consideration but does not affect the core indication function.

Engineering Selection Recommendations

The RLI-343P8CT32 is the primary substitute for the SLR-342PCTF7K based on manufacturer continuity and active product status. Selection between these components should be determined by circuit board assembly requirements:

• For surface-mount assembly processes, the SLR-342PCTF7K remains the specified component while inventory is available
• For through-hole assembly processes or designs requiring through-hole mounting, the RLI-343P8CT32 provides functional equivalence with extended supply availability
• The transition from Last Time Buy to Active status with the substitute part ensures long-term design support

Both components are manufactured by Rohm Semiconductor, maintaining consistent quality and reliability standards across the substitution.

Frequently Asked Questions (FAQ)

Q: Can the RLI-343P8CT32 directly replace the SLR-342PCTF7K in existing designs?

A: Functional replacement is possible, but circuit board design modification is required. The SLR-342PCTF7K is surface-mount (SMD), while the RLI-343P8CT32 is through-hole (T/H). PCB layout and assembly process must be adapted accordingly.

Q: Why is the SLR-342PCTF7K marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has ceased or will cease production. This designation provides a final opportunity to purchase existing inventory before the component becomes unavailable.

Q: Are both parts from the same manufacturer?

A: Yes, both the SLR-342PCTF7K and RLI-343P8CT32 are manufactured by Rohm Semiconductor, ensuring consistent design philosophy and quality standards.

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

A: The primary difference is the mounting technology. The SLR-342PCTF7K uses surface-mount packaging (SMD), while the RLI-343P8CT32 uses through-hole packaging (T/H). Both serve identical functional purposes in LED indication applications.

Q: Should I use the substitute part for new designs?

A: For new designs requiring through-hole assembly, the RLI-343P8CT32 is appropriate. For surface-mount designs, the SLR-342PCTF7K should be used while inventory permits, or alternative SMD green LED indicators from Rohm Semiconductor should be evaluated.
