KB16SKW01/UC Equivalent & Substitute Parts

Part Overview

The KB16SKW01/UC is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry with a 1A current rating at 125V AC / 30V DC. This component is designed for standard panel mount applications with front-facing installation. The product is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing maintenance, repair, and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB16SKW01/UC is determined by the following critical parameters:

• Circuit Configuration: SPDT topology must be maintained
• Switch Function: On-On operation required
• Mounting Type: Panel Mount, Front installation compatibility
• Actuator Type: Plunger for Cap design
• Operating Temperature Range: -25°C ~ 70°C minimum requirement
• Compliance Standards: RoHS3 and REACH status alignment

The YB16SKW01/UC from NKK Switches meets the core functional requirements of SPDT circuitry and On-On switching operation. However, substitution requires careful evaluation of electrical ratings and mechanical specifications, as this alternative part exhibits differences in current capacity, panel cutout dimensions, and termination style.

Parameter Comparison

Engineering Selection Recommendations

The YB16SKW01/UC presents a viable alternative to the obsolete KB16SKW01/UC for applications requiring SPDT pushbutton switch functionality. The substitute part maintains electrical compatibility at 125V AC / 30V DC and shares identical operating temperature specifications.

Key considerations for selection:

Electrical Compatibility: The YB16SKW01/UC provides 3A current capacity, exceeding the 1A requirement of the original part. This represents a performance upgrade suitable for applications where the original 1A rating is sufficient.

Mechanical Compatibility: The panel cutout dimension increases from 12.30mm to 16.00mm. This difference requires panel modification or redesign if the original mounting hole cannot be enlarged.

Termination Compatibility: The substitute part uses Solder and Quick Connect - 0.110" (2.8mm) termination, whereas the original uses Solder Lug. Circuit board layout and connector compatibility must be evaluated.

Product Status and Compliance: The YB16SKW01/UC is classified as Active, ensuring ongoing availability and support. RoHS3 compliance status for the substitute part should be confirmed with the manufacturer prior to final selection.

Lifecycle Advantage: The substitute part demonstrates superior mechanical (200,000 cycles) and electrical (100,000 cycles) life ratings, providing extended service intervals compared to the original specification.

Frequently Asked Questions (FAQ)

Q: Can the YB16SKW01/UC directly replace the KB16SKW01/UC without modifications?

A: Direct replacement requires evaluation of three factors: panel cutout diameter compatibility (16.00mm vs 12.30mm), termination style compatibility (Quick Connect vs Solder Lug), and circuit board layout accommodation. Physical panel modification may be necessary.

Q: Are the voltage and current ratings compatible between these parts?

A: Yes. Both parts operate at 125V AC / 30V DC. The YB16SKW01/UC provides higher current capacity (3A vs 1A), which is compatible with applications designed for the lower 1A rating.

Q: What is the significance of the different panel cutout dimensions?

A: The KB16SKW01/UC requires a 12.30mm circular hole, while the YB16SKW01/UC requires 16.00mm. Existing panel designs with 12.30mm holes cannot accommodate the larger substitute without enlargement or panel replacement.

Q: Does the substitute part maintain the same operating temperature range?

A: Yes. Both parts operate across -25°C to 70°C, ensuring thermal compatibility in equivalent environmental conditions.

Q: What are the implications of the different termination styles?

A: The original part uses Solder Lug termination for direct solder connection. The substitute uses Solder and Quick Connect - 0.110" (2.8mm), requiring compatible connector receptacles or alternative termination methods on the circuit board.

Q: Why does the substitute part have higher mechanical and electrical life ratings?

A: The YB16SKW01/UC is from a more recent product series with enhanced durability specifications. The 200,000 mechanical cycle and 100,000 electrical cycle ratings represent design improvements over the obsolete KB series.

Q: Is RoHS3 compliance confirmed for the substitute part?

A: RoHS3 compliance status for the YB16SKW01/UC is not specified in the provided data. Manufacturer documentation should be consulted to confirm compliance requirements for your application.
