Engineering Selection Recommendations

The YB16SKW01-5D24-JD is an active product offering from NKK Switches with ROHS3 compliance, making it suitable for applications requiring the KB16SKW01-5D24-JD. The substitute part maintains electrical compatibility across voltage and circuit specifications while providing enhanced current capacity (3A versus 1A) and extended mechanical/electrical life ratings.

Panel cutout diameter increases from 12.30mm to 16.00mm, requiring mechanical panel modification for installation. Termination options expand to include Quick Connect capability alongside solder lug configuration. The active product status ensures ongoing availability and supply chain continuity compared to the obsolete KB series.

Frequently Asked Questions (FAQ)

Q: Can YB16SKW01-5D24-JD directly replace KB16SKW01-5D24-JD in existing assemblies?

A: Electrical substitution is valid. Mechanical panel modification is required due to panel cutout diameter increase from 12.30mm to 16.00mm. Termination compatibility depends on existing wiring configuration; both solder lug and Quick Connect options are available on the substitute part.

Q: What are the key electrical compatibility factors?

A: Both parts share identical SPDT circuit configuration, On-On function, 125V AC / 30V DC voltage ratings, and 24 VDC LED amber illumination. The substitute part's 3A current rating exceeds the original 1A specification, maintaining backward compatibility for applications within the original 1A design envelope.

Q: How do mechanical life ratings affect component selection?

A: The KB16SKW01-5D24-JD specifies 100,000 mechanical cycles and 50,000 electrical cycles. The YB16SKW01-5D24-JD provides 200,000 mechanical cycles and 100,000 electrical cycles, offering extended operational life for high-cycle applications.

Q: Are there packaging or termination considerations?

A: The KB16SKW01-5D24-JD uses solder lug termination exclusively. The YB16SKW01-5D24-JD offers both solder and Quick Connect (0.110" / 2.8mm) termination options, providing installation flexibility. Packaging differs: KB series uses standard packaging; YB series uses bulk packaging.

Q: What compliance certifications apply to both parts?

A: Both KB16SKW01-5D24-JD and YB16SKW01-5D24-JD are ROHS3 compliant. The substitute part carries REACH Unaffected status. Both are classified under ECCN EAR99 and HTSUS 8536.50.9033.
