Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15CKW01-5C-JB is determined by the following critical parameters:

Core Functional Parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom)
• Voltage ratings (125V AC / 30V DC minimum)
• Illumination type and color (LED, Red)
• Illumination voltage (1.9VDC)
• Mounting type (Panel Mount, Front)
• Actuator type (Round, Button)

Mechanical Compatibility Parameters:

• Panel cutout dimensions (circular aperture)
• Termination style compatibility with existing wiring

Regulatory Compliance:

• RoHS3 compliance
• REACH status

The YB15CKW01-5C-JB qualifies as a substitute based on matching core functional parameters, identical voltage ratings, identical illumination specifications, and equivalent mounting configuration. Differences in current rating (3A vs 1A), mechanical life (1,000,000 vs 100,000 cycles), electrical life (100,000 vs 50,000 cycles), panel cutout diameter (16.00mm vs 12.30mm), and termination style represent design enhancements rather than incompatibilities.

Parameter Comparison

Engineering Selection Recommendations

The YB15CKW01-5C-JB is the designated substitute for KB15CKW01-5C-JB applications. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity.

The substitute part provides enhanced electrical performance through increased current capacity (3A vs 1A) and extended operational life ratings (1,000,000 mechanical cycles vs 100,000; 100,000 electrical cycles vs 50,000). These improvements do not compromise compatibility with the original design intent.

Panel cutout diameter increases from 12.30mm to 16.00mm, requiring mechanical panel modification. Termination style changes from solder lug to solder with quick connect option, necessitating wiring harness adaptation. These mechanical differences are manageable through standard engineering practices and do not affect electrical functionality.

The active product status of YB15CKW01-5C-JB ensures ongoing availability and supply chain reliability compared to the obsolete KB15CKW01-5C-JB.

Frequently Asked Questions (FAQ)

Q: Can YB15CKW01-5C-JB directly replace KB15CKW01-5C-JB without modifications?

A: Electrical substitution is direct. Mechanical integration requires panel cutout enlargement from 12.30mm to 16.00mm diameter and wiring harness reconfiguration to accommodate the quick connect termination option.

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

A: The substitute part supports higher current loads. In applications where the original 1A rating was sufficient, the 3A rating of YB15CKW01-5C-JB provides additional design margin and operational headroom without introducing incompatibility.

Q: Are the illumination specifications identical?

A: Yes. Both parts feature red LED illumination at 1.9VDC nominal voltage, ensuring identical visual indication and control circuit compatibility.

Q: What mechanical life improvement does the substitute provide?

A: YB15CKW01-5C-JB offers 1,000,000 mechanical cycles compared to 100,000 cycles in the original part, representing a tenfold increase in switch actuation durability.

Q: Are there compliance differences between the two parts?

A: No. Both components are ROHS3 compliant and REACH unaffected, maintaining identical regulatory status.

Q: What termination options are available with the substitute?

A: YB15CKW01-5C-JB provides both solder and quick connect 0.110" (2.8mm) termination options, offering flexibility in wiring integration compared to the solder lug only configuration of the original part.
