Substitute Part Grouping Explanation

Substitution for the SLR-342PCTB7L is based on functional equivalence within the LED indication category. The primary substitute identified is the RLI-343P8CT32, also manufactured by Rohm Semiconductor. While this substitute maintains the same functional purpose (LED indication), it differs in form factor: the SLR-342PCTB7L is a surface mount device (SMD), whereas the RLI-343P8CT32 is a through-hole (T/H) component with an oval transparent housing. Substitution between these parts requires mechanical and electrical compatibility verification at the circuit board level, including PCB layout modifications and connector interface adjustments.

Parameter Comparison

Engineering Selection Recommendations

The RLI-343P8CT32 is the identified substitute for the SLR-342PCTB7L and is currently in active production status with adequate inventory availability. Selection of this substitute requires confirmation that the through-hole mounting configuration is compatible with the target application's PCB design. The oval transparent housing of the RLI-343P8CT32 may provide enhanced visual indication compared to the standard SMD form factor of the original part. Both components are manufactured by Rohm Semiconductor, ensuring consistent quality and reliability standards.

Frequently Asked Questions (FAQ)

Q: Can the RLI-343P8CT32 be used as a direct replacement for the SLR-342PCTB7L?

A: Both components serve the same functional purpose as LED indicators. However, they differ in packaging: the SLR-342PCTB7L is surface mount, while the RLI-343P8CT32 is through-hole. Direct substitution requires PCB redesign to accommodate the different mounting method and footprint.

Q: What is the significance of the Last Time Buy status for the SLR-342PCTB7L?

A: Last Time Buy indicates that the manufacturer has ceased production of this component. The current inventory of 716 units represents the final available stock. Once depleted, this part number will no longer be available from the manufacturer.

Q: Are there any certifications or compliance standards provided for these components?

A: The provided specifications do not include certification or compliance information. Verification of applicable standards for your specific application should be conducted independently.

Q: How do the packaging differences affect component selection?

A: Packaging type determines mounting method, PCB footprint, and assembly process compatibility. SMD components require surface mount assembly equipment, while through-hole components require different soldering processes and board layout considerations. Selection must align with your manufacturing capabilities and design requirements.
