KB15SKW01-01-AB Equivalent & Substitute Parts

Part Overview

The KB15SKW01-01-AB is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 1A current rating at 125V AC. This illuminated panel mount switch operates with neon white illumination and is designed for front panel installation with a square black button actuator. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB15SKW01-01-AB is determined by the following critical parameters:

Circuit Configuration: SPDT topology must be maintained to preserve switching logic in the host system.

Voltage Ratings: AC voltage rating of 125V is the primary electrical constraint. DC rating of 30V must be supported.

Current Rating: The 1A specification establishes the minimum current-handling requirement. Substitute parts with equal or higher current ratings are electrically compatible.

Mounting Configuration: Panel mount, front installation with circular cutout is mandatory for mechanical fit.

Operating Temperature: The -25°C to 50°C range must be supported by any substitute.

Compliance: RoHS3 compliance is required for regulatory alignment.

The YB15WSKW01-6B-JB meets these substitution criteria with the following distinctions: it provides 3A current rating (exceeding the 1A requirement), maintains SPDT configuration, supports 125V AC and 30V DC ratings, and operates within the specified temperature range. The substitute features LED illumination instead of neon and requires a larger 16.00mm panel cutout diameter.

Parameter Comparison

Engineering Selection Recommendations

The YB15WSKW01-6B-JB is the designated substitute for KB15SKW01-01-AB based on electrical and mechanical compatibility. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

The substitute provides enhanced performance characteristics: 3A current rating provides 300% margin above the original 1A specification, mechanical life extends to 1,000,000 cycles versus 100,000 cycles, and electrical life doubles to 100,000 cycles. These improvements support extended operational reliability in replacement applications.

Physical integration requires accommodation of the larger 16.00mm panel cutout diameter compared to the original 12.30mm specification. Illumination differs: the substitute employs LED white illumination at 3.3 VDC versus neon white at 110 VAC. Termination configuration changes from solder lug to solder with quick connect 0.110" (2.8mm) terminals. The substitute includes IP65 ingress protection and tactile feedback features not present in the original design.

Frequently Asked Questions (FAQ)

Q: Can YB15WSKW01-6B-JB directly replace KB15SKW01-01-AB without modification?

A: Electrical substitution is valid. Mechanical integration requires panel cutout modification from 12.30mm to 16.00mm diameter. Illumination voltage supply must change from 110 VAC to 3.3 VDC. Termination style differs, requiring connector adaptation.

Q: What is the current rating relationship between these parts?

A: The substitute provides 3A rating versus the original 1A rating. This represents a higher current capacity and is electrically compatible for applications requiring 1A or less.

Q: Are both parts RoHS compliant?

A: Yes. Both KB15SKW01-01-AB and YB15WSKW01-6B-JB are ROHS3 compliant and REACH unaffected.

Q: What are the mechanical life differences?

A: KB15SKW01-01-AB specifies 100,000 mechanical cycles. YB15WSKW01-6B-JB specifies 1,000,000 mechanical cycles, providing tenfold improvement in cycle life.

Q: How do illumination systems differ?

A: The original uses neon white illumination requiring 110 VAC supply. The substitute uses LED white illumination requiring 3.3 VDC supply. This requires separate power supply modification in the host system.

Q: What packaging differences exist?

A: KB15SKW01-01-AB uses standard packaging. YB15WSKW01-6B-JB is supplied in tray packaging.

Q: Are the actuator types identical?

A: Both feature square button actuators. The original has black actuator with white window. The substitute has clear actuator with white filter/diffuser, affecting visual appearance.
