Substitute Part Grouping Explanation

Substitute parts for the SLR-342PC3FL are identified based on functional equivalence within the LED indication component category. The primary substitution criterion is the green LED indicator function across Rohm Semiconductor's product portfolio. The RLI-343P8C3F represents an active alternative that maintains the same manufacturer source and functional classification as a discrete LED indication component. Substitution logic is based on matching the core function (green LED indication) while acknowledging differences in form factor (surface-mount versus through-hole packaging).

Parameter Comparison

Engineering Selection Recommendations

The RLI-343P8C3F is an active substitute for the SLR-342PC3FL within Rohm Semiconductor's LED indication product line. Selection between these parts must account for packaging compatibility: the main part uses surface-mount technology (SMD), while the substitute employs through-hole (T/H) construction. This packaging difference requires corresponding changes to PCB layout and assembly processes. Both parts are sourced from the same manufacturer, ensuring consistent quality and reliability standards. The substitute part's active product status provides extended availability and supply chain stability compared to the main part's Last Time Buy designation.

Frequently Asked Questions (FAQ)

Q: Can the RLI-343P8C3F directly replace the SLR-342PC3FL on existing PCBs?

A: Direct PCB replacement is not possible due to packaging differences. The SLR-342PC3FL is a surface-mount component, while the RLI-343P8C3F is a through-hole component. PCB redesign and assembly process modification are required.

Q: What is the primary reason for seeking a substitute for the SLR-342PC3FL?

A: The SLR-342PC3FL carries Last Time Buy status, indicating end-of-life production. The RLI-343P8C3F provides an active alternative to ensure continued component availability.

Q: Are both parts manufactured by the same company?

A: Yes, both the SLR-342PC3FL and RLI-343P8C3F are manufactured by Rohm Semiconductor, ensuring consistent quality standards and reliability characteristics.

Q: What is the key functional difference between these parts?

A: Both parts function as green LED indicators within the discrete LED indication category. The primary difference is packaging technology: surface-mount versus through-hole construction.

Q: Is inventory availability a factor in part selection?

A: Both parts maintain adequate inventory levels (894 Pcs for the main part, 802 Pcs for the substitute). However, the substitute's active product status provides longer-term availability assurance.
