Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15SKW01B-5F-JF is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom)
• Mounting type (Panel Mount, Front)
• Actuator type (Square, Button)
• Illumination type (LED, Green)
• Operating temperature range (-25°C to 50°C)
• Termination compatibility with solder lug applications
• RoHS3 compliance

Allowable Variation Parameters:

• Current rating (substitute must equal or exceed 1A)
• Voltage ratings (substitute must equal or exceed 125V AC / 30V DC)
• Illumination voltage (nominal 2.1 VDC ±tolerance)
• Mechanical and electrical life cycles (substitute may exceed original specifications)
• Panel cutout diameter (physical panel modification may be required)

The YB15SKW01-5F-JF meets all mandatory compatibility criteria while providing enhanced electrical and mechanical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The YB15SKW01-5F-JF is a qualified substitute for the obsolete KB15SKW01B-5F-JF based on the following engineering criteria:

Functional Equivalence: Both components share identical circuit topology (SPDT), switch function (On-Mom), mounting configuration, and illumination characteristics. Electrical parameters (voltage and current ratings) are equal or superior in the substitute part.

Compliance Status: The YB15SKW01-5F-JF maintains ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity for applications requiring environmental compliance documentation.

Product Availability: The substitute part maintains active product status with documented inventory availability (1146 units), whereas the main part is obsolete. This ensures long-term supply chain viability for new designs and ongoing production requirements.

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), delivering extended operational reliability without functional compromise.

Physical Integration Consideration: Panel cutout diameter increases from 12.30mm to 16.00mm. Applications utilizing the KB15SKW01B-5F-JF require panel modification to accommodate the larger aperture of the YB15SKW01-5F-JF.

Frequently Asked Questions (FAQ)

Q: Can the YB15SKW01-5F-JF directly replace the KB15SKW01B-5F-JF without circuit modifications?

A: Yes, from an electrical and functional standpoint. Both components feature identical SPDT circuit configuration, On-Mom switch function, 125V AC / 30V DC voltage ratings, and LED green illumination. The substitute's 3A current rating exceeds the original 1A specification, providing additional capacity. Panel cutout diameter modification is required (12.30mm to 16.00mm).

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

A: The YB15SKW01-5F-JF's 3A rating indicates higher current-carrying capacity. In applications originally designed for 1A operation, the substitute operates within derated conditions, enhancing reliability and thermal margin. No circuit redesign is necessary.

Q: Are the illumination voltages (2.1 VDC versus 2.2 VDC) compatible?

A: Yes. The 0.1 VDC difference falls within standard LED forward voltage tolerance ranges. Illumination circuits designed for 2.1 VDC nominal operation function correctly with the 2.2 VDC specification.

Q: What termination differences exist between these components?

A: The KB15SKW01B-5F-JF features solder lug termination exclusively. The YB15SKW01-5F-JF provides solder and quick connect 0.110" (2.8mm) termination options. Solder lug compatibility is maintained for direct electrical substitution.

Q: Does the mechanical life difference (100,000 versus 1,000,000 cycles) affect substitution suitability?

A: The substitute's superior mechanical life rating (10x improvement) indicates enhanced durability and extended operational lifespan. This represents a performance upgrade with no negative impact on substitution compatibility.

Q: Is panel modification mandatory for physical installation?

A: Yes. The panel cutout diameter increases from 12.30mm to 16.00mm. Existing panel apertures must be enlarged to accommodate the substitute component. This is a mechanical integration requirement, not an electrical constraint.
