Key Parameters

Substitute Part Grouping Explanation

Substitution for the SLR-342PC3FN is based on functional equivalence within the LED indication category. The RLI-343P8C3F qualifies as a substitute part based on the following criteria:

• Identical manufacturer (Rohm Semiconductor)
• Same functional application (LED Indication - Discrete)
• Green LED color specification match
• Active product status, ensuring ongoing availability and support

The primary distinction between the main part and substitute is the package type: the SLR-342PC3FN uses surface-mount device (SMD) packaging, while the RLI-343P8C3F uses through-hole (T/H) packaging. This difference requires circuit board design consideration but does not affect the core LED indication functionality.

Engineering Selection Recommendations

The RLI-343P8C3F is the recommended substitute for the SLR-342PC3FN based on the following engineering criteria:

• Active product status ensures long-term availability and manufacturer support
• Identical manufacturer guarantees consistent quality standards and specifications
• Equivalent functional classification within the LED indication category
• Adequate inventory availability (802 units) supports production requirements

Selection between these parts should be determined by circuit board design requirements: SMD packaging for space-constrained or automated assembly applications, or through-hole packaging for manual assembly or breadboard prototyping.

Frequently Asked Questions (FAQ)

Q: Can the RLI-343P8C3F directly replace the SLR-342PC3FN on an existing PCB?

A: Direct PCB replacement is not possible due to package type differences. The SLR-342PC3FN uses SMD footprint, while the RLI-343P8C3F requires through-hole mounting. PCB redesign is necessary for substitution.

Q: Are there electrical performance differences between these parts?

A: Both parts are green LED indicators from Rohm Semiconductor designed for discrete LED indication applications. Electrical performance is equivalent within the LED indication category.

Q: Why is the SLR-342PC3FN in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing production. The RLI-343P8C3F, with Active status, represents the ongoing product line for green LED indication applications from Rohm Semiconductor.

Q: What inventory considerations should guide part selection?

A: The SLR-342PC3FN has 929 units available, while the RLI-343P8C3F has 802 units. For new designs, the active product status of the RLI-343P8C3F provides better long-term supply assurance.

Q: Are both parts suitable for the same application environments?

A: Both parts serve identical functional roles as green LED indicators. Application suitability depends on circuit board design constraints and assembly methodology rather than environmental factors.
