KB16SKW01-05-JC Equivalent & Substitute Parts

Part Overview

The KB16SKW01-05-JC is an illuminated pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry with on-on switching function. This component is designed for panel-mount front installation with incandescent red illumination at 5 VAC nominal voltage. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB16SKW01-05-JC is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration (SPDT) and switch function (On-On)
• Voltage ratings: 125 V AC and 30 V DC minimum
• Current rating: 1A minimum
• Mounting type: Panel Mount, Front
• Actuator type: Square, Button
• Operating temperature range: -25°C to 50°C minimum
• Termination compatibility with existing circuit board or harness

Allowable Variations:

• Current rating may exceed 1A (higher ratings are backward compatible)
• Mechanical and electrical life cycles may exceed specified minimums
• Illumination technology may differ (incandescent to LED) provided voltage compatibility is maintained
• Panel cutout diameter may vary if mechanical redesign is acceptable

The YB16SKW01-5C05-JC meets these substitution criteria while offering enhanced performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The YB16SKW01-5C05-JC is a suitable substitute for the obsolete KB16SKW01-05-JC based on electrical equivalence and functional compatibility. The substitute part maintains identical circuit configuration, voltage ratings, and operating temperature specifications.

Key Considerations for Implementation:

The substitute part introduces three design modifications that must be evaluated:

1. Panel Cutout Diameter: The YB16SKW01-5C05-JC requires a 16.00mm circular cutout compared to the original 12.30mm. Panel redesign or mechanical adaptation is necessary.

2. Illumination Technology: The substitute uses LED illumination at 5 VDC instead of incandescent at 5 VAC. Verify that the circuit power supply can provide DC voltage and that the LED color intensity meets application requirements.

3. Termination Style: The substitute offers both solder and quick-connect 0.110" (2.8mm) termination options. Existing solder lug connections require modification to accommodate the new termination interface.

The substitute part's higher current rating (3A versus 1A), increased mechanical life (200,000 versus 100,000 cycles), and doubled electrical life (100,000 versus 50,000 cycles) provide enhanced performance margins. The active product status ensures ongoing availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the YB16SKW01-5C05-JC be used as a direct drop-in replacement for the KB16SKW01-05-JC?

A: No. While the electrical specifications are compatible, three modifications are required: panel cutout enlargement from 12.30mm to 16.00mm, illumination power supply change from 5 VAC to 5 VDC, and termination interface adaptation from solder lug to solder/quick-connect 0.110" (2.8mm).

Q: What is the significance of the higher current rating on the substitute part?

A: The YB16SKW01-5C05-JC is rated for 3A (AC/DC) compared to the original 1A rating. This higher rating is backward compatible and provides additional safety margin for applications operating at or below 1A. No circuit modification is required due to the higher rating.

Q: Does the LED illumination change affect circuit design?

A: Yes. The substitute part requires 5 VDC illumination supply instead of 5 VAC. Verify that your circuit power distribution includes a DC supply at this voltage. LED illumination typically draws less current than incandescent, which may reduce overall power consumption.

Q: Are there compliance differences between the two parts?

A: The KB16SKW01-05-JC is confirmed ROHS3 compliant. RoHS compliance status for the YB16SKW01-5C05-JC is not specified in the provided data. For regulated applications, confirm compliance documentation with the manufacturer before implementation.

Q: What is the impact of the larger panel cutout diameter?

A: The substitute requires a 16.00mm diameter cutout versus 12.30mm for the original part. This necessitates mechanical panel redesign or use of an adapter bezel. Evaluate whether panel modification is feasible for your application.

Q: How do the mechanical and electrical life ratings affect component selection?

A: The substitute part offers doubled mechanical life (200,000 cycles versus 100,000) and doubled electrical life (100,000 cycles versus 50,000). These higher ratings indicate improved durability and longer service intervals, beneficial for high-cycle applications.
