KB15CKW01-01-JB Equivalent & Substitute Parts

Part Overview

The KB15CKW01-01-JB is an illuminated pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 1A current rating at 125V AC. This component is designed for panel-mounted front installation with neon white illumination. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and redesign applications where continued functionality is required.

Parameter Comparison

Engineering Selection Recommendations

The YB15CKW01-5F24-JB is an active product with ROHS3 compliance and REACH unaffected status, providing regulatory continuity with the obsolete KB15CKW01-01-JB. Both components maintain identical voltage ratings (125V AC / 30V DC) and circuit configuration (SPDT), establishing electrical compatibility at the switching level.

Selection of the YB15CKW01-5F24-JB requires evaluation of the following design considerations:

Current Rating: The substitute provides 3A capacity versus the original 1A specification. This increased rating is backward-compatible for applications operating at or below 1A.

Panel Cutout Diameter: The substitute requires a 16.00mm circular cutout compared to the original 12.30mm diameter. Panel modification is necessary for mechanical installation.

Illumination System: The substitute employs LED green illumination at 24 VDC versus neon white at 110 VAC. Electrical supply and visual indication characteristics differ and must be accommodated in circuit design.

Termination: The substitute offers solder and quick-connect options versus solder lug only on the original. Wiring methodology must align with available termination options.

Operational Life: The substitute provides extended mechanical (1,000,000 cycles) and electrical (100,000 cycles) life ratings, supporting enhanced system reliability.

Frequently Asked Questions (FAQ)

Q: Can the YB15CKW01-5F24-JB directly replace the KB15CKW01-01-JB without modifications?

A: Direct replacement requires panel cutout modification from 12.30mm to 16.00mm diameter and electrical supply adjustment for illumination (from 110 VAC neon to 24 VDC LED). The switching circuit remains compatible at 125V AC / 30V DC with SPDT configuration.

Q: What are the key electrical compatibility factors?

A: Both components maintain identical voltage ratings (125V AC / 30V DC) and SPDT circuit configuration. The substitute's 3A current rating exceeds the original 1A specification, providing backward compatibility for lower-current applications.

Q: Does the illumination color change affect system functionality?

A: Illumination color change from white (neon) to green (LED) is a visual indicator change only. Functional switching operation remains unaffected. System design must accommodate the different illumination voltage requirement (110 VAC to 24 VDC).

Q: Are there packaging or inventory considerations?

A: The KB15CKW01-01-JB is obsolete with 920 pieces in stock. The YB15CKW01-5F24-JB is an active product with 882 pieces available in bulk packaging, providing long-term supply continuity.

Q: What compliance certifications apply to both components?

A: Both components are ROHS3 compliant and REACH unaffected, maintaining regulatory alignment for industrial and commercial applications.

Q: How do the operational life ratings compare?

A: The substitute provides significantly extended operational life: mechanical life increases from 100,000 to 1,000,000 cycles, and electrical life increases from 50,000 to 100,000 cycles, supporting applications requiring higher cycle counts.
