KB15CKW01-6B-JB Equivalent & Substitute Parts

Part Overview

The KB15CKW01-6B-JB is a pushbutton switch with SPDT (Single Pole Double Throw) circuit configuration, designed for panel mount applications with front illumination. This component features a 1A current rating at 125V AC and white LED illumination at 3.3VDC nominal voltage. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where this specification remains applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15CKW01-6B-JB is determined by the following critical parameters:

• Circuit Configuration: Must maintain SPDT topology
• Switch Function: Must preserve On-Mom (momentary) operation
• Voltage Ratings: AC rating must meet or exceed 125V; DC rating must meet or exceed 30V
• Illumination Specification: LED illumination at 3.3VDC nominal voltage required
• Mounting Configuration: Panel mount, front-facing installation capability
• Actuator Type: Round button actuator
• Operating Temperature Range: Must support -25°C to 50°C minimum
• Compliance: ROHS3 compliance required

The YB15CKW01-6B-JB qualifies as a substitute based on these parameters. While it exhibits higher current rating (3A versus 1A), larger panel cutout diameter (16.00mm versus 12.30mm), and enhanced mechanical/electrical life specifications, these represent improvements that do not compromise backward compatibility for applications within the original 1A current specification.

Parameter Comparison

Engineering Selection Recommendations

The YB15CKW01-6B-JB is the designated substitute for the obsolete KB15CKW01-6B-JB. Selection of the YB15CKW01-6B-JB is supported by the following factors:

• Product Status: The substitute maintains Active status, ensuring continued availability and supply chain reliability
• Compliance Alignment: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements
• Functional Equivalence: Identical circuit configuration, switch function, voltage ratings, and illumination specifications ensure direct functional compatibility
• Enhanced Reliability: 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 improved longevity for equivalent or lower-stress applications
• Current Capacity: The 3A rating of the substitute accommodates all applications within the original 1A specification without derating

Panel cutout diameter differences (16.00mm substitute versus 12.30mm original) and termination style variations (Quick Connect option available on substitute) require mechanical and electrical interface verification during integration.

Frequently Asked Questions (FAQ)

Q: Can the YB15CKW01-6B-JB directly replace the KB15CKW01-6B-JB in existing designs?

A: Functional replacement is supported for applications operating within the original 1A current specification. Mechanical compatibility requires verification of panel cutout diameter accommodation (16.00mm versus 12.30mm original). Termination style differences must be evaluated for circuit board or harness integration.

Q: What are the key differences between these two parts?

A: Primary differences include current rating (3A versus 1A), mechanical life (1,000,000 versus 100,000 cycles), electrical life (100,000 versus 50,000 cycles), panel cutout diameter (16.00mm versus 12.30mm), and termination options. Voltage ratings, circuit configuration, illumination specification, and operating temperature range remain identical.

Q: Does the higher current rating of the substitute create any compatibility issues?

A: No. Higher current rating represents increased capacity and does not compromise operation in lower-current applications. The substitute is suitable for any application within the original 1A specification.

Q: Are there packaging differences between these parts?

A: The main part is supplied in standard packaging, while the substitute is available in bulk packaging. This distinction affects procurement and inventory management but does not impact component functionality or performance.

Q: What compliance certifications apply to both parts?

A: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements for electronic component distribution and use.
