Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB15SKW01-12-FF 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 current ratings are acceptable. Mounting type (panel mount, front) and panel cutout dimensions must be compatible with existing mechanical interfaces. Illumination color (green) should match for visual consistency in control panels. Operating temperature range and mechanical/electrical life specifications must satisfy application requirements.

The substitute part YB15SKW01-5F12-JF from NKK Switches meets these substitution criteria while offering enhanced performance characteristics and active product status.

Parameter Comparison

Engineering Selection Recommendations

The YB15SKW01-5F12-JF is a qualified substitute for the KB15SKW01-12-FF based on matching circuit configuration, switch function, and voltage ratings. The substitute part maintains ROHS3 compliance and REACH unaffected status, consistent with the original component.

Key considerations for implementation: The substitute part features a larger panel cutout diameter (16.00mm versus 12.30mm), requiring mechanical panel modification. The termination style differs, offering both solder and quick connect options versus solder lug only. The illumination system transitions from incandescent to LED technology with 12 VDC supply instead of 12 VAC. Current rating increases from 1A to 3A, providing additional capacity. Mechanical and electrical life ratings are substantially improved in the substitute part.

The active product status of YB15SKW01-5F12-JF ensures long-term availability and supply chain continuity compared to the obsolete KB15SKW01-12-FF.

Frequently Asked Questions (FAQ)

Q: Can YB15SKW01-5F12-JF directly replace KB15SKW01-12-FF without modifications?

A: Functional substitution is possible with mechanical and electrical interface modifications. The larger panel cutout diameter requires panel modification. Termination style differences necessitate wiring reconfiguration. Illumination voltage supply must change from 12 VAC to 12 VDC.

Q: Are the voltage and current ratings compatible?

A: Yes. The substitute part maintains 125V AC and 30V DC ratings, meeting or exceeding the original specifications. The increased current rating (3A versus 1A) is acceptable for applications designed for the original 1A component.

Q: What is the impact of switching from incandescent to LED illumination?

A: LED illumination offers extended operational life and reduced power consumption. The supply voltage changes from 12 VAC to 12 VDC, requiring circuit modification. Visual appearance remains green in both configurations.

Q: Does the panel cutout size difference affect compatibility?

A: Yes. The substitute part requires a 16.00mm diameter cutout versus 12.30mm for the original. Existing panel installations must be mechanically modified to accommodate the larger opening.

Q: Are both parts RoHS compliant?

A: Yes. Both KB15SKW01-12-FF and YB15SKW01-5F12-JF are ROHS3 compliant and REACH unaffected.

Q: What are the termination differences?

A: The original part uses solder lug termination. The substitute offers both solder and quick connect (0.110" / 2.8mm) options, providing installation flexibility.
