KB15SKW01-A Equivalent & Substitute Parts

Part Overview

The KB15SKW01-A is a 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 standard panel mount applications with front-facing actuator orientation. The product is currently classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15SKW01-A is determined by the following critical parameters:

Circuit configuration must remain SPDT to maintain electrical compatibility with existing circuit designs. Switch function must be On-Mom (momentary) to preserve operational behavior. Voltage ratings must meet or exceed the original specifications: 125V AC minimum and 30V DC minimum. Current rating must be equal to or greater than 1A to ensure safe operation under load conditions. Mounting type must be Panel Mount, Front to ensure mechanical compatibility with existing panel cutouts and installation procedures. Operating temperature range must encompass or exceed -25°C to 70°C to maintain performance across the specified environmental conditions. RoHS and REACH compliance status must be maintained for regulatory adherence.

The YB15SKW01-FB substitute part satisfies these core substitution criteria while offering enhanced electrical and mechanical life ratings.

Parameter Comparison

Engineering Selection Recommendations

The YB15SKW01-FB is a qualified substitute for the KB15SKW01-A based on electrical and mechanical compatibility. Both components maintain identical circuit configuration (SPDT), switch function (On-Mom), voltage ratings (125V AC / 30V DC), and operating temperature range (-25°C ~ 70°C). The substitute part provides superior current handling capacity (3A versus 1A) and extended mechanical and electrical life ratings, offering enhanced reliability margins for the application.

The YB15SKW01-FB maintains ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component. The substitute part is currently in active production status, providing long-term availability and supply chain stability compared to the obsolete KB15SKW01-A.

Physical integration requires consideration of panel cutout dimensions: the KB15SKW01-A specifies a 12.30mm circular cutout, while the YB15SKW01-FB requires a 16.00mm circular cutout. Termination style differs between components (Solder Lug versus Solder/Quick Connect 0.110"), necessitating circuit board modification or adapter implementation for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can the YB15SKW01-FB directly replace the KB15SKW01-A without modifications?

A: Electrical substitution is valid based on circuit configuration, voltage ratings, and operating parameters. However, mechanical integration requires panel cutout enlargement from 12.30mm to 16.00mm diameter and termination style adaptation from Solder Lug to Solder/Quick Connect 0.110" configuration.

Q: What are the key compatibility criteria for substituting the KB15SKW01-A?

A: Substitute parts must maintain SPDT circuit configuration, On-Mom switch function, minimum 125V AC and 30V DC voltage ratings, Panel Mount Front mounting type, and -25°C to 70°C operating temperature range. Current rating must equal or exceed 1A.

Q: Why does the YB15SKW01-FB have higher current and life ratings?

A: The YB15SKW01-FB represents a more recent design iteration within the NKK Switches product family, incorporating enhanced contact materials and mechanical design that extend both electrical and mechanical life specifications while supporting higher current loads.

Q: Are there compliance differences between the two parts?

A: Both components maintain ROHS3 compliance and REACH unaffected status. No regulatory compliance differences exist between the KB15SKW01-A and YB15SKW01-FB.

Q: What packaging considerations apply to the substitute part?

A: The KB15SKW01-A is supplied in standard packaging, while the YB15SKW01-FB is supplied in bulk packaging. Procurement quantities and handling procedures may differ accordingly.
