KB15RKW01-JC Equivalent & Substitute Parts

Part Overview

The KB15RKW01-JC is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 1A current rating at 125V AC / 30V DC. This component is designed for standard panel mount, front installation applications with a rectangular button actuator and solder lug termination. The product is currently obsolete, making identification of suitable substitute components essential for ongoing maintenance, repair, and design continuity in legacy systems.

Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Compatibility Criteria:

• Circuit configuration must be SPDT
• Switch function must be On-Momentary
• Voltage ratings must meet or exceed: 125V AC and 30V DC
• Mounting type must be Panel Mount, Front
• Actuator type must be Rectangular Button
• Operating temperature range must encompass -25°C to 70°C

Acceptable Variation Parameters:

• Current rating may exceed 1A (higher ratings are backward compatible)
• Mechanical and electrical life cycles may exceed specified minimums
• Termination style may differ if mechanical and electrical connection is maintained
• Panel cutout diameter may vary within mechanical design constraints
• Product status may differ (Active substitutes are acceptable for obsolete parts)

The YB15RKW01-JC meets the mandatory criteria while exceeding performance specifications in current rating, mechanical life, and electrical life, making it a valid substitute component.

Parameter Comparison

Engineering Selection Recommendations

The YB15RKW01-JC is a direct substitute for the obsolete KB15RKW01-JC based on electrical and mechanical compatibility. Both components are manufactured by NKK Switches and share identical circuit configuration, switch function, voltage ratings, and operating temperature specifications.

Key Considerations:

The YB15RKW01-JC offers enhanced performance characteristics: 3A current rating (versus 1A), 1,000,000 mechanical cycles (versus 100,000), and 100,000 electrical cycles (versus 50,000). These improvements provide greater operational margin in applications where the original component is no longer available.

Panel cutout diameter differs between components: KB15RKW01-JC requires 12.30mm, while YB15RKW01-JC requires 16.00mm. This dimensional difference necessitates mechanical panel modification for direct substitution in existing installations.

Termination style differs: KB15RKW01-JC uses solder lug termination, while YB15RKW01-JC provides both solder and quick connect options. Electrical connection methodology must be evaluated against existing circuit board or wiring infrastructure.

Both components maintain identical RoHS3 compliance status and REACH unaffected classification, ensuring regulatory continuity in replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the YB15RKW01-JC directly replace the KB15RKW01-JC without any modifications?

A: Electrical substitution is valid; however, mechanical panel modifications are required due to panel cutout diameter differences (12.30mm versus 16.00mm). Termination style differences must also be addressed in circuit connection design.

Q: What are the key electrical parameters that determine substitution compatibility?

A: Circuit configuration (SPDT), switch function (On-Momentary), voltage ratings (125V AC / 30V DC minimum), and current rating (equal or greater) are the primary electrical criteria. Both components meet these requirements.

Q: Is the higher current rating of the YB15RKW01-JC (3A versus 1A) a concern for applications designed for 1A?

A: No. Higher current ratings are backward compatible and do not create operational issues in lower-current applications. The component will function correctly in circuits designed for 1A operation.

Q: What is the significance of the different panel cutout diameters?

A: Panel cutout diameter is a mechanical installation parameter. The YB15RKW01-JC requires a larger cutout (16.00mm versus 12.30mm), necessitating physical panel modification or use of an adapter mounting solution for direct replacement in existing installations.

Q: Are there any compliance or regulatory differences between these components?

A: Both components share identical ECCN (EAR99) and HTSUS (8536.50.9031) classifications. RoHS3 compliance is confirmed for the KB15RKW01-JC; compliance status for the YB15RKW01-JC is not specified in available documentation.

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

A: The YB15RKW01-JC provides extended operational life (1,000,000 mechanical cycles and 100,000 electrical cycles versus 100,000 and 50,000 respectively). This enhancement may provide longer service intervals in high-cycle applications.
