Key Parameters

Substitute Part Grouping Explanation

Substitution for the SLR-342PC3FJ is based on the following criteria derived from the provided parameters:

• Functional Category: LED Indication - Discrete
• Color Specification: Green
• Manufacturer Continuity: Rohm Semiconductor
• Package Compatibility: Through-hole or surface mount variants within the same product family

The substitute part RLI-343P8C3F maintains functional equivalence as a green LED indicator from the same manufacturer, though it utilizes a through-hole (T/H) package configuration rather than surface mount. This represents a package variant within Rohm Semiconductor's LED indicator portfolio.

Parameter Comparison

Engineering Selection Recommendations

The RLI-343P8C3F serves as a functional substitute for the SLR-342PC3FJ based on shared manufacturer origin and identical product category classification. The primary distinction is the package configuration: the main part utilizes surface mount technology while the substitute employs through-hole mounting.

Selection between these parts depends on circuit board design requirements:

• SLR-342PC3FJ is appropriate for surface mount assembly processes and compact PCB layouts
• RLI-343P8C3F is appropriate for through-hole assembly processes and applications requiring manual insertion or legacy board designs

Both parts are manufactured by Rohm Semiconductor and maintain active inventory availability, with the substitute part currently in Active product status, ensuring long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can RLI-343P8C3F directly replace SLR-342PC3FJ on an existing PCB?

A: Direct PCB replacement is not possible without design modification. The SLR-342PC3FJ is a surface mount component requiring SMD pads, while the RLI-343P8C3F is a through-hole component requiring drilled holes and plated vias. PCB layout redesign is necessary for substitution.

Q: Are both parts functionally identical for LED indication applications?

A: Both parts are classified as green LED indicators for discrete indication applications from Rohm Semiconductor. Functional equivalence is established by shared manufacturer, color specification, and product category.

Q: What is the significance of the product status difference?

A: The SLR-342PC3FJ is in Last Time Buy status, meaning production will cease. The RLI-343P8C3F is in Active status, indicating ongoing manufacturing and long-term availability. For new designs, the Active part provides superior supply chain continuity.

Q: Should package type influence the substitution decision?

A: Package type is a critical selection criterion. The choice between surface mount and through-hole depends entirely on the assembly process, PCB design, and manufacturing capabilities of the end application. Both package types are valid for LED indication; the selection is application-specific.
