KB15SKW01-5D24-JB Equivalent & Substitute Parts

Part Overview

The KB15SKW01-5D24-JB is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with LED illumination. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The switch is designed for panel-mount front installation with solder lug termination and operates at 1A current rating across 125V AC and 30V DC voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15SKW01-5D24-JB is determined by the following critical parameters:

Circuit configuration must remain SPDT to maintain electrical functionality within existing designs. Voltage ratings (125V AC / 30V DC) establish the maximum operational envelope and cannot be reduced. Illumination specifications (LED, Amber, 24 VDC) must match to preserve visual indication consistency. Mounting type (Panel Mount, Front) and panel cutout dimensions determine physical compatibility with existing enclosures.

The YB15SKW01-5D24-JB qualifies as a substitute based on matching these core parameters. However, the following differences exist and must be evaluated for specific applications:

Current rating increases from 1A to 3A, providing enhanced capacity for higher-load circuits. Panel cutout diameter increases from 12.30mm to 16.00mm, requiring mechanical modification to mounting surfaces. Termination style changes from Solder Lug to Solder with Quick Connect 0.110" (2.8mm), affecting circuit board integration. Mechanical life extends from 100,000 to 1,000,000 cycles, and electrical life extends from 50,000 to 100,000 cycles. Product status transitions from Obsolete to Active, ensuring continued availability and support.

Parameter Comparison

Engineering Selection Recommendations

The YB15SKW01-5D24-JB is an active substitute for the obsolete KB15SKW01-5D24-JB. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing and deployment.

Selection of the YB15SKW01-5D24-JB requires evaluation of three primary considerations:

Mechanical integration: The increased panel cutout diameter (16.00mm versus 12.30mm) necessitates modification to existing panel mounting holes. This change is not reversible without panel rework.

Electrical capacity: The 3A current rating provides operational margin above the original 1A specification. Applications operating at or near 1A will experience no functional change. Applications requiring current capacity between 1A and 3A benefit from the enhanced rating.

Termination compatibility: The transition from Solder Lug to Solder with Quick Connect 0.110" (2.8mm) termination requires circuit board redesign or adapter implementation. Direct pin-for-pin substitution is not possible without termination modification.

The extended mechanical life (1,000,000 cycles) and electrical life (100,000 cycles) of the YB15SKW01-5D24-JB provide improved reliability margins compared to the original component specifications.

Frequently Asked Questions (FAQ)

Q: Can the YB15SKW01-5D24-JB be used as a direct replacement without any modifications?

A: No. The panel cutout diameter increases from 12.30mm to 16.00mm, and the termination style changes from Solder Lug to Solder with Quick Connect 0.110" (2.8mm). Both mechanical and electrical modifications are required.

Q: Are the voltage and circuit specifications identical between the two parts?

A: Yes. Both components feature SPDT circuit configuration, 125V AC / 30V DC voltage ratings, and identical illumination specifications (LED, Amber, 24 VDC). These core electrical parameters are preserved in the substitute.

Q: What is the significance of the increased current rating from 1A to 3A?

A: The higher current rating provides operational capacity for circuits requiring up to 3A. Existing circuits operating at 1A will function identically. The increased rating does not affect voltage or circuit configuration.

Q: Does the larger panel cutout diameter affect the switch's functional performance?

A: No. The panel cutout diameter is a mechanical mounting specification only. It does not affect electrical performance, switching characteristics, or illumination function. However, it requires physical modification to the mounting panel.

Q: Are both components compliant with current regulatory standards?

A: Yes. Both the KB15SKW01-5D24-JB and YB15SKW01-5D24-JB are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for manufacturing and deployment.

Q: What is the practical advantage of the extended mechanical and electrical life ratings?

A: The YB15SKW01-5D24-JB provides 10x greater mechanical life (1,000,000 versus 100,000 cycles) and 2x greater electrical life (100,000 versus 50,000 cycles). These extended ratings reduce replacement frequency and improve system reliability over extended operational periods.

Q: Can the termination style difference be resolved with an adapter?

A: Adapter solutions may be possible depending on circuit board layout and available space. However, such adaptations are application-specific and require custom engineering evaluation. Direct termination compatibility does not exist.
