Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LB25SKW01-05-FJ is determined by the following critical parameters:

• Circuit configuration (DPDT requirement)
• Current and voltage ratings (3A at 125V AC minimum)
• Mounting type (Panel Mount, Snap-In)
• Illumination characteristics (Incandescent, Green, 5VAC)
• Panel cutout dimensions (Square 16.20mm x 16.20mm)
• Mechanical and electrical life specifications
• Environmental compliance (RoHS3, REACH status)

The substitute part LB25SKW01-5F05-JF belongs to the same LB series base product family (LB25SKW), indicating design compatibility within the NKK Switches product line. Both components share the same HTSUS and ECCN classifications, confirming regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

The LB25SKW01-5F05-JF is classified as an active product within the NKK Switches LB series, providing supply continuity for applications currently using the obsolete LB25SKW01-05-FJ. Both components share identical ECCN and HTSUS classifications, confirming regulatory equivalence for export and trade purposes.

The substitute part maintains MSL Level 1 rating, indicating no moisture sensitivity constraints during storage and handling. Selection of the active substitute part is supported by its current product status and ongoing manufacturer support, reducing long-term supply chain risk compared to obsolete alternatives.

Verification of mechanical fit, electrical performance under actual load conditions, and illumination color matching should be conducted within the context of the specific application circuit before full production implementation.

Frequently Asked Questions (FAQ)

Q: Why is the LB25SKW01-05-FJ classified as obsolete?

A: The LB25SKW01-05-FJ has reached end-of-life status within the NKK Switches product portfolio. The active substitute LB25SKW01-5F05-JF provides functional continuity for applications requiring DPDT illuminated pushbutton switches with equivalent electrical and mechanical specifications.

Q: What are the critical parameters for substitution compatibility?

A: Substitution compatibility is determined by DPDT circuit configuration, 3A current rating at 125V AC, panel mount snap-in mounting type, green incandescent illumination at 5VAC, and square 16.20mm panel cutout dimensions. Mechanical life of 1,000,000 cycles and electrical life of 100,000 cycles must be maintained.

Q: Are there differences in RoHS or REACH compliance between the main part and substitute?

A: The main part LB25SKW01-05-FJ is explicitly ROHS3 compliant and REACH unaffected. Compliance data for the substitute part LB25SKW01-5F05-JF is not provided in the available specifications. Compliance verification should be obtained directly from NKK Switches for the substitute part before implementation in regulated applications.

Q: Can the LB25SKW01-5F05-JF be used as a direct replacement in existing assemblies?

A: Both parts share identical panel cutout dimensions (16.20mm square), mounting type (panel mount snap-in), and termination style (solder, quick connect 0.110"). Physical and electrical compatibility is supported by these matching specifications. However, full functional validation within the specific application circuit is required before production deployment.

Q: What is the inventory status for these components?

A: The main part LB25SKW01-05-FJ has 982 pieces in stock as new original inventory. The substitute part LB25SKW01-5F05-JF has 1,059 pieces in stock as new original inventory. Availability should be confirmed with the component supplier for current procurement requirements.
