Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB15RKW01-05-EB is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration (SPDT)
• Switch function (On-Momentary)
• Voltage ratings (125V AC minimum, 30V DC minimum)
• Mounting type (Panel Mount, Front)
• Actuator type (Rectangular Button)
• Operating temperature range (-25°C to +50°C minimum)
• Termination style compatibility

Allowable Variation Parameters:

• Current rating (substitute must meet or exceed 1A)
• Illumination type (incandescent or LED acceptable)
• Illumination color (yellow or amber acceptable for visual indication)
• Mechanical and electrical life (substitute may exceed original specifications)
• Panel cutout diameter (mechanical accommodation required)

The YB15RKW01-5D05-JD meets all mandatory compatibility requirements while exceeding performance specifications in current rating, mechanical life, and electrical life. The primary design difference involves LED illumination versus incandescent, panel cutout diameter increase, and termination style variation.

Parameter Comparison

Engineering Selection Recommendations

The YB15RKW01-5D05-JD is a functionally equivalent substitute for the obsolete KB15RKW01-05-EB based on the following engineering criteria:

Electrical Compatibility: Both components maintain identical voltage ratings (125V AC, 30V DC) and circuit configuration (SPDT). The substitute's 3A current rating exceeds the original 1A specification, providing margin for circuit protection and component reliability.

Mechanical Compatibility: Both switches feature identical mounting type (Panel Mount, Front) and actuator configuration (Rectangular Button). The panel cutout diameter increases from 12.30mm to 16.00mm, requiring mechanical panel modification for direct replacement.

Product Status: The substitute is classified as Active, ensuring long-term availability and supply chain continuity compared to the obsolete original part.

Compliance: Both components are ROHS3 compliant, maintaining regulatory alignment for applications subject to hazardous substance restrictions.

Performance Enhancement: The substitute provides 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.

Illumination Consideration: The transition from incandescent yellow to LED amber illumination requires verification of circuit compatibility, as the substitute operates at 5VDC versus the original 5VAC specification. LED illumination provides reduced power consumption and extended operational life compared to incandescent technology.

Frequently Asked Questions (FAQ)

Q: Can the YB15RKW01-5D05-JD directly replace the KB15RKW01-05-EB without panel modification?

A: No. The panel cutout diameter differs (16.00mm versus 12.30mm). Panel drilling or enlargement is required for mechanical installation. Electrical connections are compatible with appropriate termination adaptation.

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

A: The illumination voltage changes from 5VAC to 5VDC. Circuits supplying 5VAC illumination voltage require modification to provide 5VDC. LED illumination reduces power consumption and extends operational life compared to incandescent technology.

Q: Are the voltage and current ratings compatible between these components?

A: Yes. The substitute maintains identical voltage ratings (125V AC, 30V DC) and exceeds the current rating (3A versus 1A). The higher current rating provides additional safety margin and does not create incompatibility with circuits designed for 1A operation.

Q: What is the significance of the mechanical life difference?

A: The substitute provides 10x greater mechanical life (1,000,000 cycles versus 100,000 cycles). This enhancement extends component service intervals and reduces replacement frequency in high-cycle switching applications.

Q: Are there termination style differences that affect installation?

A: Yes. The original part uses Solder Lug termination, while the substitute uses Solder and Quick Connect 0.110" (2.8mm) termination. Wiring harness or connector adaptation may be required depending on existing circuit board design.

Q: Is the substitute suitable for applications requiring ROHS3 compliance?

A: The original part is explicitly ROHS3 compliant. The substitute's ROHS status is not specified in available documentation. Verification with the manufacturer is recommended for applications with mandatory ROHS compliance requirements.
