KB15SKW01-JB Equivalent & Substitute Parts

Part Overview

The KB15SKW01-JB is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with On-Momentary switch function. This component is rated for 1A at 125V AC and 30V DC, designed for standard panel mount front installation with a circular 12.30mm diameter cutout. The product is currently obsolete, making identification of suitable substitute components essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB15SKW01-JB is determined by strict alignment of the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration (SPDT required)
• Switch function (On-Momentary operation)
• Voltage ratings (minimum 125V AC, 30V DC)
• Current rating (minimum 1A AC/DC)
• Mounting type (Panel Mount, Front)
• Actuator type (Square Button)
• Operating temperature range (-25°C to 70°C minimum)
• Panel cutout dimensions (mechanical fit requirement)

The YB15SKW01-JB qualifies as a substitute component. While it features enhanced electrical and mechanical life ratings (1,000,000 mechanical cycles and 100,000 electrical cycles versus 100,000 and 50,000 respectively), it maintains all mandatory compatibility parameters. The YB15SKW01-JB exceeds the current rating specification (3A versus 1A) and features an alternative termination style (Solder, Quick Connect - 0.110" versus Solder Lug), which requires circuit board redesign consideration. The panel cutout diameter increases to 16.00mm, necessitating mechanical panel modification.

Parameter Comparison

Engineering Selection Recommendations

The YB15SKW01-JB is electrically compatible with the KB15SKW01-JB for applications requiring SPDT On-Momentary pushbutton switch functionality at 125V AC and 30V DC. Both components are manufactured by NKK Switches and maintain identical voltage and temperature specifications.

Selection of the YB15SKW01-JB as a substitute requires evaluation of the following implementation factors:

Electrical Considerations: The YB15SKW01-JB current rating of 3A exceeds the original 1A specification, providing additional margin for circuit protection and component longevity. Electrical and mechanical life ratings are doubled, extending component service life in high-cycle applications.

Mechanical Considerations: The panel cutout diameter increases from 12.30mm to 16.00mm, requiring mechanical panel modification. The termination style change from Solder Lug to Solder Quick Connect (0.110" / 2.8mm) necessitates circuit board redesign and potential wiring harness modification.

Compliance Status: Both components maintain MSL 1 (Unlimited) moisture sensitivity rating. The KB15SKW01-JB is ROHS3 compliant; RoHS compliance status for the YB15SKW01-JB is not specified in available data and should be confirmed with the manufacturer prior to selection for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can the YB15SKW01-JB directly replace the KB15SKW01-JB without any modifications?

A: No. While electrically compatible, the YB15SKW01-JB requires two modifications: (1) panel cutout enlargement from 12.30mm to 16.00mm diameter, and (2) circuit board redesign to accommodate the Quick Connect termination style (0.110" / 2.8mm) instead of Solder Lug termination.

Q: Are the voltage and current ratings of the YB15SKW01-JB suitable for applications designed for the KB15SKW01-JB?

A: Yes. The YB15SKW01-JB maintains identical voltage ratings (125V AC, 30V DC) and exceeds the current rating (3A versus 1A). Applications operating at or below the original 1A specification are electrically compatible.

Q: What is the impact of the increased mechanical and electrical life ratings?

A: The YB15SKW01-JB provides extended component service life with 1,000,000 mechanical cycles and 100,000 electrical cycles compared to 100,000 and 50,000 cycles respectively for the KB15SKW01-JB. This is beneficial for high-cycle or mission-critical applications.

Q: Is the YB15SKW01-JB RoHS compliant?

A: RoHS compliance status for the YB15SKW01-JB is not specified in the provided technical data. Confirmation with the manufacturer is required for applications subject to RoHS regulations.

Q: What are the termination style differences and their implications?

A: The KB15SKW01-JB uses Solder Lug termination for direct PCB soldering. The YB15SKW01-JB uses Solder Quick Connect (0.110" / 2.8mm) termination, requiring either a mating connector or circuit board pad redesign. This change affects assembly methods and wiring harness compatibility.
