Substitute Part Grouping Explanation

Substitution for the SLR-342PCTF7L 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 packaging format: the SLR-342PCTF7L uses surface-mount technology (SMD), while the RLI-343P8CT32 uses through-hole (T/H) packaging with an oval color-transparent lens design.

Engineering Selection Recommendations

The RLI-343P8CT32 is the identified substitute for the SLR-342PCTF7L based on manufacturer continuity and functional category alignment. Selection between these parts depends on circuit board design requirements:

• For surface-mount assemblies, the SLR-342PCTF7L remains the primary choice while inventory is available, given its Last Time Buy status
• For through-hole designs or new designs where packaging flexibility exists, the RLI-343P8CT32 provides an active, long-term available alternative from the same manufacturer
• The transition from SMD to through-hole packaging requires corresponding changes to PCB layout and assembly processes
• Both components are manufactured by Rohm Semiconductor, maintaining consistency in electrical performance and reliability characteristics

Frequently Asked Questions (FAQ)

Q: Can the RLI-343P8CT32 directly replace the SLR-342PCTF7L in existing designs?

A: Direct replacement is not possible without PCB redesign. The SLR-342PCTF7L uses surface-mount packaging, while the RLI-343P8CT32 uses through-hole packaging. These require different footprints and assembly methods.

Q: What is the significance of the Last Time Buy status for the SLR-342PCTF7L?

A: Last Time Buy indicates that Rohm Semiconductor has announced the end of production for this part. Current inventory of 691 pieces represents the final available stock. New designs should transition to active alternatives such as the RLI-343P8CT32.

Q: Are both parts from the same manufacturer?

A: Yes, both the SLR-342PCTF7L and RLI-343P8CT32 are manufactured by Rohm Semiconductor, ensuring alignment in quality standards and reliability specifications.

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

A: The main differences are packaging format (SMD versus through-hole) and lens design (standard versus oval transparent). Both serve discrete LED indication applications.

Q: Should I stock the RLI-343P8CT32 as a substitute?

A: The RLI-343P8CT32 is suitable for new designs or applications where through-hole packaging is acceptable. For existing designs using the SLR-342PCTF7L, available inventory should be secured before Last Time Buy deadlines.
