Key Parameters

Substitute Part Grouping Explanation

Substitution for the SLR-332PC3FK is based on the following criteria:

• Functional equivalence as a green LED indicator component
• Manufacturer compatibility (Rohm Semiconductor)
• Application category (LED Indication - Discrete)
• Active product status to ensure ongoing availability

The identified substitute part RLI-343P8C3F meets these substitution criteria. While the main part uses surface mount packaging (SMD), the substitute employs through-hole (T/H) packaging. This represents a mechanical packaging change that requires circuit board redesign considerations but maintains functional equivalence for LED indication purposes.

Parameter Comparison

Engineering Selection Recommendations

The RLI-343P8C3F is the identified substitute for the SLR-332PC3FK based on functional equivalence and active product status. Selection between these parts depends on circuit board design requirements:

• Use SLR-332PC3FK for existing designs requiring surface mount packaging and available inventory
• Use RLI-343P8C3F for new designs requiring long-term supply assurance, as this part maintains active status with Rohm Semiconductor

The packaging transition from SMD to through-hole requires corresponding modifications to printed circuit board layout and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RLI-343P8C3F directly replace SLR-332PC3FK without design changes?

A: Both parts function as green LED indicators from Rohm Semiconductor. However, the packaging difference (SMD versus through-hole) requires circuit board redesign. Direct board-level substitution is not possible without layout modifications.

Q: Why is SLR-332PC3FK in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing this product line. RLI-343P8C3F, with active status, represents the recommended path for designs requiring extended production life.

Q: Are both parts from the same manufacturer?

A: Yes, both SLR-332PC3FK and RLI-343P8C3F are manufactured by Rohm Semiconductor, ensuring consistent quality and reliability standards.

Q: What is the primary difference between these parts?

A: The primary difference is packaging technology. SLR-332PC3FK uses surface mount device (SMD) technology, while RLI-343P8C3F uses through-hole (T/H) technology. Both serve identical functional purposes as green LED indicators.
