Substitute Part Grouping Explanation

Substitution for the SLR-342PCTB7M 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 classification

The key differentiator is the packaging format: the original part uses surface-mount technology (SMD), while the substitute uses through-hole (T/H) configuration with oval color transparent housing. Design integration must account for this mechanical and electrical interface change.

Parameter Comparison

Engineering Selection Recommendations

Selection between the SLR-342PCTB7M and RLI-343P8CT32 depends on design constraints and production timeline:

For existing designs currently using the SLR-342PCTB7M, the available inventory of 713 pieces supports near-term production requirements. However, the Last Time Buy status indicates this supply is finite and non-replenishable.

The RLI-343P8CT32 is the recommended path forward for new designs and long-term production planning. Its Active product status ensures sustained availability and supply chain reliability. The through-hole configuration requires PCB layout modification compared to the surface-mount original, but this change is a standard engineering practice in component transition scenarios.

Both parts originate from Rohm Semiconductor, maintaining consistency in manufacturing standards and reliability characteristics within the LED indication product family.

Frequently Asked Questions (FAQ)

Q: Can the RLI-343P8CT32 be used as a direct drop-in replacement for the SLR-342PCTB7M?

A: No. While both components function as green LED indicators, they differ in packaging technology. The SLR-342PCTB7M uses surface-mount (SMD) configuration, while the RLI-343P8CT32 uses through-hole (T/H) configuration. PCB layout and footprint modifications are required.

Q: What is the significance of the Last Time Buy status?

A: Last Time Buy indicates that Rohm Semiconductor has announced end-of-life for the SLR-342PCTB7M. The current inventory of 713 pieces represents the final available stock. No future production or replenishment is planned.

Q: Why is the RLI-343P8CT32 recommended despite the packaging difference?

A: The RLI-343P8CT32 maintains Active product status, ensuring long-term availability and supply chain continuity. It performs the same functional role as an LED indicator. The packaging change, while requiring design modification, is a standard transition approach in component lifecycle management.

Q: Are there electrical performance differences between these parts?

A: Both components are classified as LED Indication - Discrete devices from the same manufacturer. Specific electrical parameters (forward voltage, luminous intensity, wavelength) are not provided in the available data. Detailed datasheets should be consulted for precise electrical specifications.

Q: What inventory considerations apply to each part?

A: The SLR-342PCTB7M has 713 pieces available with no future replenishment. The RLI-343P8CT32 has 941 pieces currently in stock with ongoing availability due to its Active status.
