KB16SKW01-5C05-JC Equivalent & Substitute Parts

Part Overview

The KB16SKW01-5C05-JC is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with integrated LED illumination. This component is designed for panel-mount applications with front-facing installation and operates at 1A (AC/DC) with 125V AC / 30V DC voltage ratings. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB16SKW01-5C05-JC is evaluated based on the following critical parameters that must align for functional equivalence:

Mandatory Matching Parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Mounting type (Panel Mount, Front)
• Illumination type and color (LED, Red)
• Illumination voltage (5 VDC)
• Voltage ratings (125V AC / 30V DC minimum)
• Operating temperature range (-25°C to 50°C)
• RoHS compliance status

Allowable Variation Parameters:

• Current rating (substitute may exceed 1A)
• Mechanical and electrical life cycles (substitute may exceed specified values)
• Panel cutout diameter (physical panel modification may be required)
• Termination style (electrical compatibility must be verified for circuit integration)
• Product status (active alternatives preferred for obsolete parts)

The YB16SKW01-5C05-JC meets all mandatory matching criteria while providing enhanced electrical life ratings and higher current capacity, making it a qualified substitute within the NKK Switches product family.

Parameter Comparison

Engineering Selection Recommendations

The YB16SKW01-5C05-JC is an active-status substitute for the obsolete KB16SKW01-5C05-JC. Both components maintain ROHS3 compliance and EAR99 export classification, ensuring regulatory continuity in applications requiring these certifications.

Key considerations for component selection:

Electrical Compatibility: The YB16SKW01-5C05-JC provides 3A current capacity compared to the original 1A rating. This enhanced capacity is backward-compatible with circuits designed for 1A operation and provides additional margin for applications approaching the original current limit.

Mechanical Integration: The substitute part requires a 16.00mm panel cutout diameter versus the original 12.30mm specification. Panel modifications are necessary for physical installation. The YB series actuator maintains the same square button profile and red LED illumination characteristics.

Termination Differences: The original part uses solder lug termination, while the substitute offers both solder and quick-connect 0.110" (2.8mm) options. Circuit integration must account for this termination style change during board redesign or retrofit procedures.

Lifecycle Performance: The YB16SKW01-5C05-JC doubles both 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 YB16SKW01-5C05-JC directly replace the KB16SKW01-5C05-JC without circuit modifications?

A: Electrical circuit compatibility is maintained due to identical SPDT configuration, voltage ratings, and illumination specifications. However, panel cutout diameter differences (12.30mm vs. 16.00mm) require mechanical panel modification. Termination style differences (solder lug vs. solder/quick-connect) necessitate circuit board connection redesign.

Q: What is the impact of the higher 3A current rating on the original 1A circuit design?

A: The 3A rating is a higher capacity specification that does not negatively affect circuits designed for 1A operation. The substitute part operates safely at or below the original 1A current levels. No circuit derating is required.

Q: Are there compatibility concerns with the different termination styles?

A: The original solder lug termination differs from the substitute's solder and quick-connect options. Electrical function remains identical, but physical connection points on the circuit board must be adapted to accommodate the new termination geometry.

Q: Does the larger panel cutout diameter affect the switch's electrical performance?

A: Panel cutout diameter is a mechanical specification that does not affect electrical performance. The larger 16.00mm cutout on the YB16SKW01-5C05-JC is a physical mounting consideration only and requires panel modification for installation.

Q: Are both parts compliant with the same regulatory standards?

A: Yes. Both the KB16SKW01-5C05-JC and YB16SKW01-5C05-JC maintain ROHS3 compliance and EAR99 export classification, ensuring regulatory continuity for applications requiring these certifications.

Q: What is the significance of the doubled mechanical and electrical life ratings?

A: The YB16SKW01-5C05-JC provides 200,000 mechanical cycles and 100,000 electrical cycles compared to the original 100,000 and 50,000 cycles respectively. This represents extended component longevity and reduced maintenance frequency in high-cycle applications.
