Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LB25SKW01-28-JC is determined by strict equivalence across the following critical parameters:

Circuit configuration (DPDT), switch function (On-Mom), current rating (3A AC/DC), voltage ratings (125V AC / 30V DC), mounting type (Panel Mount, Snap-In), actuator type (Square, Button), panel cutout dimensions (16.20mm x 16.20mm), and termination style (Solder, Quick Connect - 0.110" / 2.8mm) must remain identical.

The LB25SKW01-5C24-JC qualifies as a substitute based on these core electrical and mechanical parameters. The primary difference lies in the illumination specification: the substitute employs LED red illumination at 24 VDC instead of incandescent red illumination at 28 VAC/DC. This distinction affects only the illumination circuit and does not impact the switch's primary electrical function or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The LB25SKW01-5C24-JC is the qualified substitute for the obsolete LB25SKW01-28-JC. Both components maintain identical electrical performance specifications, mechanical compatibility, and regulatory compliance status (ROHS3 Compliant, REACH Unaffected).

The substitute part carries Active product status, ensuring continued availability and supply chain reliability. The transition from incandescent to LED illumination represents a technology advancement that reduces power consumption and extends operational life while maintaining the same visual indication function.

Selection of the LB25SKW01-5C24-JC requires verification that the system's illumination power supply can accommodate the 24 VDC requirement in place of the original 28 VAC/DC specification. This is the sole design consideration for implementation.

Frequently Asked Questions (FAQ)

Q: Can the LB25SKW01-5C24-JC directly replace the LB25SKW01-28-JC in existing assemblies?

A: Mechanical and electrical compatibility is confirmed. The substitute maintains identical DPDT circuit configuration, 3A current rating, 125V AC / 30V DC voltage ratings, panel cutout dimensions, and termination style. The illumination circuit requires independent verification to confirm 24 VDC availability in the host system.

Q: What is the primary difference between these two parts?

A: The illumination source differs. The original part uses incandescent red illumination powered at 28 VAC/DC. The substitute uses LED red illumination powered at 24 VDC. Both provide equivalent visual indication and occupy the same physical footprint.

Q: Why is the original part classified as obsolete?

A: The LB25SKW01-28-JC is no longer in active production. The LB25SKW01-5C24-JC represents the current active equivalent within the LB series, incorporating LED technology for improved reliability and reduced power consumption.

Q: Are there any compliance or certification differences?

A: Both parts maintain identical regulatory status: ROHS3 Compliant and REACH Unaffected. No compliance barriers exist for substitution.

Q: What packaging options are available?

A: The original part is supplied in standard packaging. The substitute is available in Bulk packaging configuration.
