Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15SKW01-5C12-JC is determined by the following critical parameters:

Circuit configuration (SPDT) and switch function (On-Mom) must remain identical. Voltage ratings must meet or exceed the original specifications: 125V AC and 30V DC minimum. Current rating must support the application load; higher ratings are acceptable. Mounting type (Panel Mount, Front) and illumination characteristics (LED, Red, 12VDC) must match to ensure mechanical and electrical compatibility with existing panel installations. Operating temperature range and RoHS compliance must be maintained.

The YB15SKW01-5C12-JC qualifies as a substitute based on these criteria: it maintains SPDT circuit configuration and On-Mom function, meets voltage requirements (125V AC, 30V DC), and provides enhanced current capacity (3A versus 1A). Illumination specifications are identical. Panel mount configuration is preserved. RoHS3 compliance is maintained.

Parameter Comparison

Engineering Selection Recommendations

The YB15SKW01-5C12-JC is a qualified substitute for the KB15SKW01-5C12-JC based on functional equivalence and compliance requirements. The substitute maintains all critical electrical and mechanical parameters while offering enhanced performance characteristics. The active product status of the YB15SKW01-5C12-JC ensures ongoing availability and supply chain continuity, addressing the obsolescence of the original component.

The substitute provides superior mechanical and electrical life ratings (1,000,000 and 100,000 cycles respectively versus 100,000 and 50,000 cycles), supporting extended operational reliability. Both components maintain ROHS3 compliance and identical voltage/current specifications for the application circuit. The panel cutout diameter difference (16.00mm versus 12.30mm) requires mechanical panel modification for installation.

Frequently Asked Questions (FAQ)

Q: Can the YB15SKW01-5C12-JC directly replace the KB15SKW01-5C12-JC without circuit modifications?

A: Electrical circuit compatibility is confirmed. The substitute maintains identical SPDT configuration, voltage ratings (125V AC, 30V DC), and illumination specifications (LED, Red, 12VDC). No circuit redesign is required. Mechanical panel modification is necessary due to the larger panel cutout diameter (16.00mm versus 12.30mm).

Q: What are the key differences between these two components?

A: The primary differences are current rating (3A versus 1A), mechanical life (1,000,000 versus 100,000 cycles), electrical life (100,000 versus 50,000 cycles), panel cutout diameter (16.00mm versus 12.30mm), and product status (Active versus Obsolete). The substitute offers enhanced durability and higher current capacity.

Q: Is the higher current rating of the substitute problematic for applications designed for 1A?

A: No. Higher current ratings are compatible with lower-current applications. The 3A rating of the substitute provides design margin and does not affect operation in circuits specified for 1A maximum.

Q: What packaging differences exist between these parts?

A: The KB15SKW01-5C12-JC uses standard packaging, while the YB15SKW01-5C12-JC is supplied in Tray packaging. This difference does not affect component functionality or electrical performance.

Q: Are both components RoHS compliant?

A: Yes. Both the KB15SKW01-5C12-JC and YB15SKW01-5C12-JC are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.
