Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB16RKG01-5C12-JC is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Current rating (0.4VA AC/DC minimum)
• Voltage rating (28V AC/DC minimum)
• Illumination type and color (LED, Red)
• Illumination voltage (12VDC nominal)
• Mounting type (Panel Mount, Front)
• Operating temperature range (-25°C to 50°C minimum)
• Actuator type (Rectangular, Button)

Allowable Variations:

• Panel cutout diameter (mechanical accommodation)
• Termination style (solder lug vs. quick connect)
• Mechanical and electrical life ratings (equal or greater)
• Product status (active preferred for obsolete parts)

The YB16RKG01-5C12-JC qualifies as a substitute based on matching all critical electrical parameters and exceeding mechanical life specifications.

Parameter Comparison

Engineering Selection Recommendations

The YB16RKG01-5C12-JC is a qualified substitute for the obsolete KB16RKG01-5C12-JC based on electrical and mechanical parameter alignment. The substitute part offers the following advantages:

• Active product status ensures ongoing availability and supply chain continuity
• Mechanical life rating of 200,000 cycles exceeds the original specification of 100,000 cycles
• Identical electrical performance across all critical parameters (voltage, current, circuit configuration, illumination)
• Equivalent operating temperature range and moisture sensitivity classification

Design consideration: The panel cutout diameter increases from 12.30mm to 16.00mm. Panel modifications or adapter hardware may be required for direct mechanical replacement in existing installations. The termination style change from solder lug to quick connect (0.110" / 2.8mm) requires verification of PCB or harness compatibility.

Frequently Asked Questions (FAQ)

Q: Can the YB16RKG01-5C12-JC directly replace the KB16RKG01-5C12-JC in existing assemblies?

A: Electrical substitution is direct. Mechanical compatibility requires verification of panel cutout dimensions (12.30mm vs. 16.00mm) and termination connection type (solder lug vs. quick connect). Panel drilling or adapter hardware may be necessary.

Q: What are the critical parameters that define substitution eligibility?

A: SPDT circuit configuration, On-On switch function, 0.4VA current rating at 28V AC/DC, LED red illumination at 12VDC nominal, rectangular button actuator, panel-mount front installation, and -25°C to 50°C operating temperature range must all match or exceed the original specification.

Q: Why is the panel cutout diameter different between these parts?

A: The KB and YB series have different mechanical designs. The YB16RKG01-5C12-JC requires a 16.00mm circular cutout compared to the 12.30mm cutout of the KB16RKG01-5C12-JC. This is a mechanical design difference between series, not a functional limitation.

Q: Does the termination style change affect electrical performance?

A: No. Both solder lug and quick connect (0.110" / 2.8mm) termination styles provide equivalent electrical connectivity. Selection depends on PCB design and assembly process compatibility.

Q: Is the YB16RKG01-5C12-JC RoHS compliant?

A: RoHS compliance status is not specified in the available data for the YB16RKG01-5C12-JC. Verify with the manufacturer if RoHS3 compliance is a requirement for your application.

Q: What is the advantage of the higher mechanical life rating on the substitute part?

A: The YB16RKG01-5C12-JC is rated for 200,000 mechanical cycles compared to 100,000 cycles on the original part. This provides extended operational life and improved reliability in high-cycle applications.
