KB16SKW01-CC Equivalent & Substitute Parts

Part Overview

The KB16SKW01-CC is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry with On-On switching function. This component is rated for 1A at 125V AC and 30V DC, designed for standard panel mount front installation with a red square button actuator and solder lug termination. The product is currently obsolete, making identification of suitable substitute components essential for ongoing maintenance, repair, and new design applications where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB16SKW01-CC is determined by strict alignment of electrical and mechanical parameters. The primary substitute identified is the YB16WSKW01-CB, which maintains compatibility through the following critical parameters:

Circuit configuration (SPDT) and switch function (On-On) are identical, ensuring functional equivalence in switching logic. Voltage ratings remain constant at 125V AC and 30V DC, allowing direct replacement in existing circuits without modification. Mounting type (Panel Mount, Front) and actuator type (Square, Button) are preserved, maintaining mechanical compatibility with existing panel installations.

Key differences that do not prevent substitution include: current rating increase from 1A to 3A (higher rating provides greater operational margin), mechanical life extension from 100,000 to 200,000 cycles, electrical life extension from 50,000 to 100,000 cycles, and enhanced ingress protection (IP65). The panel cutout diameter increases from 12.30mm to 16.00mm, requiring panel modification. Termination style changes from Solder Lug to Solder with Quick Connect 0.110" (2.8mm), necessitating connector adaptation. The substitute part is Active status, ensuring ongoing availability.

Parameter Comparison

Engineering Selection Recommendations

The YB16WSKW01-CB is a qualified substitute for the KB16SKW01-CC based on electrical parameter alignment and active product status. Both components maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility.

Selection of the YB16WSKW01-CB requires evaluation of mechanical integration constraints. The increased panel cutout diameter (16.00mm versus 12.30mm) necessitates panel modification or use of adapter hardware. The termination style change from Solder Lug to Solder with Quick Connect 0.110" (2.8mm) requires circuit board redesign or connector adaptation.

The substitute part provides enhanced operational characteristics: 3A current rating (versus 1A), 200,000 mechanical cycle life (versus 100,000), 100,000 electrical cycle life (versus 50,000), and IP65 ingress protection. These improvements support extended service life and enhanced environmental resistance in applications where the original 1A rating is adequate.

Frequently Asked Questions (FAQ)

Q: Can the YB16WSKW01-CB directly replace the KB16SKW01-CC without modification?

A: Electrical substitution is direct; the circuits are functionally equivalent with identical voltage ratings and SPDT configuration. Mechanical integration requires panel cutout enlargement from 12.30mm to 16.00mm diameter and termination connector adaptation from Solder Lug to Quick Connect 0.110" (2.8mm).

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

A: The higher current rating of the substitute part provides greater operational margin and does not prevent substitution in circuits designed for 1A operation. The substitute can safely handle the original circuit's current demands.

Q: Are both parts compliant with current regulatory standards?

A: Both the KB16SKW01-CC and YB16WSKW01-CB are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What does the IP65 rating on the substitute part provide?

A: The YB16WSKW01-CB's IP65 ingress protection rating indicates dust-tight and water-resistant performance. The original KB16SKW01-CC does not specify ingress protection, making the substitute suitable for applications requiring enhanced environmental resistance.

Q: How do the mechanical and electrical life ratings affect component selection?

A: The substitute part's extended mechanical life (200,000 cycles versus 100,000) and electrical life (100,000 cycles versus 50,000) indicate longer operational durability. Selection depends on application cycle requirements and expected service life.

Q: What packaging considerations apply to these components?

A: The KB16SKW01-CC is packaged as individual units; the YB16WSKW01-CB is supplied in bulk packaging. Procurement quantities and inventory management practices should account for this difference.
