Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15RKW01-5F-JB is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration must remain SPDT
• Mounting type must be Panel Mount, Front
• Illumination type must be LED, Green
• Operating temperature range must encompass -25°C to 50°C
• Voltage ratings must meet or exceed AC 125V and DC 30V requirements
• Termination compatibility with solder connection methods

Allowable Variation Parameters:

• Current rating may exceed 1A (higher current capacity is acceptable for lower-current applications)
• Mechanical and electrical life cycles may exceed specified minimums
• Panel cutout diameter may differ if mechanical redesign is acceptable
• Illumination voltage may vary within LED operating tolerances
• Product status may transition from obsolete to active

The YB15RKW01-5F-JB qualifies as a substitute based on these criteria, with enhancements in current capacity, cycle life, and active product status.

Engineering Selection Recommendations

The YB15RKW01-5F-JB is a qualified substitute for the obsolete KB15RKW01-5F-JB based on the following engineering criteria:

Compliance & Regulatory Status: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications subject to environmental directives.

Electrical Compatibility: The substitute maintains identical voltage ratings (125V AC, 30V DC) and circuit configuration (SPDT), ensuring direct functional equivalence in existing circuit designs. The increased current rating of 3A provides enhanced capacity margin for the original 1A specification.

Mechanical & Operational Durability: The YB15RKW01-5F-JB demonstrates superior mechanical life (1,000,000 cycles versus 100,000 cycles) and electrical life (100,000 cycles versus 50,000 cycles), extending component service life in high-cycle applications.

Product Availability: The transition from obsolete to active product status ensures long-term supply chain continuity and availability for replacement and new installations.

Termination Consideration: The substitute offers dual termination options (Solder and Quick Connect 0.110"), providing flexibility beyond the original solder lug configuration. Applications requiring solder lug termination must specify this requirement during procurement.

Panel Integration: The panel cutout diameter increases from 12.30mm to 16.00mm, requiring mechanical redesign of panel mounting fixtures if physical retrofit is required.

Frequently Asked Questions (FAQ)

Q: Can the YB15RKW01-5F-JB directly replace the KB15RKW01-5F-JB in existing applications?

A: Electrical and functional replacement is direct. The substitute maintains identical SPDT circuit configuration, voltage ratings, and illumination specifications. Panel cutout diameter differs (16.00mm versus 12.30mm), requiring mechanical panel modification for physical installation.

Q: What is the significance of the increased current rating (3A versus 1A)?

A: The higher current rating provides design margin and allows the component to handle applications with current demands up to 3A without derating. Existing 1A applications operate well within the substitute's capacity.

Q: Are there termination compatibility issues between the two parts?

A: The original KB15RKW01-5F-JB uses solder lug termination exclusively. The YB15RKW01-5F-JB offers solder and quick connect options. For solder-based circuit integration, specify solder termination during procurement to ensure compatibility with existing PCB or wiring harness designs.

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

A: The YB15RKW01-5F-JB provides 10x greater mechanical life (1,000,000 versus 100,000 cycles), extending service intervals and reducing replacement frequency in high-cycle switching applications.

Q: What are the implications of the illumination voltage difference (2.1V versus 2.2V)?

A: The 0.1V difference falls within standard LED operating tolerances and does not affect functional illumination performance. Both specifications ensure reliable green LED operation across the specified temperature range.

Q: Does the active product status of the substitute provide supply chain advantages?

A: Yes. The YB15RKW01-5F-JB's active status ensures ongoing manufacturing, documented availability, and long-term procurement reliability compared to the obsolete KB15RKW01-5F-JB.
