Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15RKG01-05-EB is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be SPDT
• Switch function must be On-Mom (momentary)
• Current rating must support 0.4VA minimum at both AC and DC
• Voltage rating must support 28V AC and 28V DC operation
• Illumination voltage must be compatible with 5V source

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount, Front
• Actuator type must be Rectangular Button
• Panel cutout dimensions must accommodate the component
• Termination style must be compatible with solder lug connections

Environmental & Compliance Requirements:

• Operating temperature range must encompass -25°C to +50°C
• RoHS3 compliance required
• Moisture Sensitivity Level (MSL) must be 1 or equivalent

The YB15RKG01-5D05-JD meets the core electrical and mechanical requirements for substitution, with noted differences in illumination technology, mechanical life rating, and panel cutout dimensions that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The YB15RKG01-5D05-JD is an active product substitute for the obsolete KB15RKG01-05-EB, maintaining electrical equivalence across all critical switching parameters. Both components are ROHS3 compliant and operate within the specified -25°C to +50°C temperature range.

Key considerations for selection:

Illumination Technology Transition: The substitute employs LED amber illumination with 5 VDC supply, replacing the incandescent yellow illumination with 5 VAC supply. This represents a technology upgrade with improved efficiency and extended operational life.

Mechanical Life Enhancement: The YB15RKG01-5D05-JD provides 1,000,000 mechanical cycles compared to 100,000 cycles in the original part, offering extended component longevity.

Panel Integration Modification: The substitute requires a 16.00mm diameter panel cutout versus 12.30mm for the original part. Existing panel designs must accommodate this dimensional change.

Termination Compatibility: The substitute offers dual termination options (Solder and Quick Connect 0.110"), providing flexibility beyond the solder lug termination of the original part.

Frequently Asked Questions (FAQ)

Q: Can the YB15RKG01-5D05-JD directly replace the KB15RKG01-05-EB in existing designs?

A: Electrical substitution is valid. Panel cutout dimensions differ (16.00mm vs. 12.30mm), requiring mechanical redesign. Illumination voltage changes from 5 VAC to 5 VDC, necessitating circuit evaluation.

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

A: LED illumination provides extended operational life, improved efficiency, and color shift from yellow to amber. Power supply requirements change from AC to DC at the same 5V nominal level.

Q: Are both parts ROHS3 compliant?

A: Yes, both KB15RKG01-05-EB and YB15RKG01-5D05-JD are ROHS3 compliant.

Q: What are the termination differences between these parts?

A: The KB15RKG01-05-EB uses solder lug termination. The YB15RKG01-5D05-JD provides solder and quick connect 0.110" (2.8mm) termination options, offering greater flexibility for circuit board integration.

Q: Does the mechanical life rating difference affect electrical performance?

A: Mechanical life rating (100,000 vs. 1,000,000 cycles) indicates switch durability and cycle longevity. Electrical life remains equivalent at 100,000 cycles for both parts. Selection depends on application duty cycle requirements.

Q: What packaging is available for the substitute part?

A: The YB15RKG01-5D05-JD is supplied in bulk packaging, compared to the original part's standard packaging configuration.
