SLR-332PCT32K LED Indication Component - Equivalent & Substitute Parts

Part Overview

The SLR-332PCT32K is a green LED indicator component manufactured by Rohm Semiconductor, classified as an LED Indication discrete component in surface-mount device (SMD) packaging. This part is designated as Last Time Buy status, indicating limited availability and the necessity to identify equivalent alternatives for ongoing production requirements or future design revisions.

Locating suitable substitute components ensures design continuity and supply chain resilience when the primary part reaches end-of-life status.

Substitute Part Grouping Explanation

Substitute components for the SLR-332PCT32K are identified based on functional equivalence within the LED indication category. The RLI-343P8CT32 serves as a manufacturer-recommended alternative from Rohm Semiconductor.

The substitution logic is based on the following criteria:

• Functional classification: LED Indication - Discrete
• Manufacturer alignment: Rohm Semiconductor
• Component type compatibility: LED indicator function
• Active product status availability

The RLI-343P8CT32 differs in physical form factor (through-hole oval configuration versus surface-mount) and maintains active production status, providing long-term supply assurance.

Parameter Comparison

Engineering Selection Recommendations

Selection between the SLR-332PCT32K and RLI-343P8CT32 depends on design constraints and supply requirements:

The SLR-332PCT32K remains available with adequate inventory (1189 units) for current production cycles. However, Last Time Buy status indicates this part will not be replenished beyond existing stock.

The RLI-343P8CT32 is recommended for new designs or long-term production planning due to its Active product status, ensuring continued availability and supply chain stability. This substitute requires board layout modification to accommodate through-hole mounting versus surface-mount configuration.

Selection should prioritize Active status components for designs requiring extended production lifecycles or high-volume manufacturing commitments.

Frequently Asked Questions (FAQ)

Q: Can the RLI-343P8CT32 directly replace the SLR-332PCT32K on existing PCBs?

A: No. The RLI-343P8CT32 uses through-hole (T/H) mounting, while the SLR-332PCT32K uses surface-mount (SMD) packaging. PCB layout and footprint modifications are required.

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

A: Last Time Buy indicates the manufacturer will not produce additional units beyond current inventory. The SLR-332PCT32K should be considered for end-of-life replacement planning.

Q: Are both parts from the same manufacturer?

A: Yes. Both the SLR-332PCT32K and RLI-343P8CT32 are manufactured by Rohm Semiconductor, ensuring consistent quality and performance standards.

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

A: The main differences are packaging format (SMD versus through-hole) and product lifecycle status (Last Time Buy versus Active). Both serve LED indication functions within the Rohm Semiconductor product line.

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

A: For designs currently using the SLR-332PCT32K, evaluate whether packaging format changes are acceptable. If through-hole mounting is feasible, the RLI-343P8CT32 provides long-term supply assurance due to Active status.
