KB15RKW01-05-JC Equivalent & Substitute Parts

Part Overview

The KB15RKW01-05-JC is an illuminated pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 1A current rating at 125V AC. This component is designed for panel-mounted front installation with incandescent red illumination at 5VAC nominal voltage. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15RKW01-05-JC is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom momentary operation)
• Voltage ratings (125V AC minimum, 30V DC)
• Mounting type (Panel Mount, Front)
• Actuator type (Rectangular Button)
• Illumination color (Red)
• Operating temperature range (-25°C to 50°C minimum)
• Panel cutout dimensions (mechanical fit requirement)

Allowable Variations:

• Current rating may exceed 1A (higher ratings are backward compatible)
• Illumination technology may differ (LED acceptable as functional equivalent to incandescent)
• Illumination voltage may differ if within standard supply ranges (5VDC acceptable as equivalent to 5VAC)
• Mechanical and electrical life ratings may exceed minimum specifications
• Termination style may vary (Quick Connect acceptable as alternative to Solder Lug)

The YB15RKW01-5C05-JC meets all mandatory compatibility parameters while offering enhanced performance characteristics in current rating, mechanical life, and electrical life.

Parameter Comparison

Engineering Selection Recommendations

The YB15RKW01-5C05-JC is a direct functional substitute for the obsolete KB15RKW01-05-JC. Both components are manufactured by NKK Switches and maintain identical electrical specifications for circuit configuration, voltage ratings, and operating temperature range.

Advantages of YB15RKW01-5C05-JC:

• Active product status ensures ongoing availability and supply chain continuity
• Current rating of 3A provides margin above the 1A requirement
• LED illumination offers extended operational life and reduced power consumption compared to incandescent technology
• Mechanical life rating of 1,000,000 cycles and electrical life of 100,000 cycles exceed the original specifications
• ROHS3 compliance maintained

Installation Considerations:

• Panel cutout diameter increases from 12.30mm to 16.00mm, requiring mechanical modification to mounting panel
• Termination style includes Quick Connect option in addition to solder capability, providing installation flexibility
• Illumination voltage changes from 5VAC to 5VDC, requiring circuit supply adjustment

Both components maintain ROHS3 compliance and are suitable for the operating temperature range of -25°C to 50°C.

Frequently Asked Questions (FAQ)

Q: Can YB15RKW01-5C05-JC directly replace KB15RKW01-05-JC without circuit modification?

A: Electrical substitution is direct. The higher current rating (3A vs 1A) is backward compatible. However, illumination voltage changes from 5VAC to 5VDC, requiring adjustment to the illumination supply circuit. Panel cutout diameter increases from 12.30mm to 16.00mm, necessitating mechanical panel modification.

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

A: LED illumination provides identical red color output with extended operational life and reduced power consumption. Both technologies are functionally equivalent for visual indication purposes. The 5VDC LED supply replaces the 5VAC incandescent supply.

Q: Are the termination options interchangeable?

A: The YB15RKW01-5C05-JC offers both solder and Quick Connect termination options. Solder lug termination from the original KB15RKW01-05-JC can be replicated using the solder termination option on the substitute part. Quick Connect termination provides an alternative installation method.

Q: Does the larger panel cutout diameter affect compatibility?

A: The panel cutout diameter increases from 12.30mm to 16.00mm. Existing panel mounting holes sized for 12.30mm will require enlargement to accommodate the substitute component. This is a mechanical modification requirement, not an electrical compatibility issue.

Q: Are both components RoHS compliant?

A: Both KB15RKW01-05-JC and YB15RKW01-5C05-JC maintain ROHS3 compliance, ensuring regulatory alignment for applications requiring RoHS certification.
