Key Parameters

Substitute Part Grouping Explanation

The YB15CKW01-EB qualifies as a substitute based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Circuit configuration: SPDT (identical)
• Switch function: On-Mom (identical)
• Voltage rating - AC: 125V (identical)
• Voltage rating - DC: 30V (identical)
• Mounting type: Panel Mount, Front (identical)
• Actuator type: Round, Button (identical)
• Operating temperature range: -25°C ~ 70°C (identical)
• RoHS compliance: ROHS3 Compliant (identical)

Differing Parameters:

• Current rating: 3A vs. 1A (higher capacity in substitute)
• Mechanical life: 1,000,000 cycles vs. 100,000 cycles (enhanced durability)
• Electrical life: 100,000 cycles vs. 50,000 cycles (enhanced durability)
• Panel cutout dimensions: 16.00mm Dia vs. 12.30mm Dia (larger footprint)
• Termination style: Solder, Quick Connect - 0.110" vs. Solder Lug (different connection method)
• Product status: Active vs. Obsolete (current availability)

The YB15CKW01-EB provides electrical compatibility with superior performance characteristics. Panel cutout dimension differences and termination style variations require mechanical and installation assessment for specific applications.

Parameter Comparison

Engineering Selection Recommendations

The YB15CKW01-EB is available as an active product from NKK Switches, whereas the KB15CKW01-EB is obsolete. Both components maintain ROHS3 compliance and identical voltage specifications (125V AC / 30V DC).

Selection of the YB15CKW01-EB as a substitute requires verification of mechanical compatibility due to panel cutout dimension differences (16.00mm vs. 12.30mm). The increased current rating (3A vs. 1A) and enhanced mechanical/electrical life cycles provide performance margin for the application. Termination style differences (Solder, Quick Connect - 0.110" vs. Solder Lug) necessitate circuit board layout and connector compatibility assessment.

For applications where the original 1A current rating is a design constraint, the higher capacity of the substitute does not create functional incompatibility. The active product status of YB15CKW01-EB ensures supply chain availability and ongoing manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can YB15CKW01-EB directly replace KB15CKW01-EB in existing designs?

A: Electrical compatibility is confirmed across voltage ratings, circuit configuration, and switch function. Mechanical compatibility requires assessment of panel cutout dimensions (16.00mm vs. 12.30mm) and termination style differences (Solder, Quick Connect - 0.110" vs. Solder Lug).

Q: What is the significance of the higher current rating in YB15CKW01-EB?

A: The YB15CKW01-EB is rated for 3A versus 1A in the KB15CKW01-EB. This higher capacity does not create incompatibility for applications designed for 1A operation and provides additional performance margin.

Q: Are there compliance differences between these parts?

A: Both components are ROHS3 compliant and carry identical REACH and ECCN classifications (REACH Unaffected, EAR99). No compliance barriers exist for substitution.

Q: Why is panel cutout dimension important for substitution?

A: The KB15CKW01-EB requires a 12.30mm circular cutout, while YB15CKW01-EB requires 16.00mm. Existing panel designs may require modification to accommodate the larger footprint of the substitute.

Q: What are the termination differences?

A: KB15CKW01-EB uses Solder Lug termination, while YB15CKW01-EB provides Solder and Quick Connect - 0.110" (2.8mm) options. Circuit board layout and connector compatibility must be verified for the specific application.

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

A: YB15CKW01-EB provides 1,000,000 mechanical cycles and 100,000 electrical cycles compared to 100,000 and 50,000 cycles respectively for KB15CKW01-EB. Enhanced durability in the substitute supports extended service life applications.
