Engineering Selection Recommendations

The YB15CKW01-FB is a direct functional substitute for the KB15CKW01-FB based on electrical and mechanical compatibility. Both components are manufactured by NKK Switches and maintain identical circuit configuration, switch function, voltage ratings, and operating temperature specifications. The YB15CKW01-FB offers enhanced performance characteristics with higher current capacity (3A vs 1A), extended mechanical life (1,000,000 vs 100,000 cycles), and extended electrical life (100,000 vs 50,000 cycles).

The YB15CKW01-FB holds active product status with current manufacturing availability, addressing the obsolescence of the KB15CKW01-FB. Both components maintain ROHS3 compliance and equivalent environmental specifications.

Physical installation considerations include panel cutout diameter difference (16.00mm vs 12.30mm), requiring panel modification for direct mechanical substitution. Termination style differs between solder lug and solder with quick connect options, requiring evaluation of circuit board connection methodology.

Frequently Asked Questions (FAQ)

Q: Can the YB15CKW01-FB replace the KB15CKW01-FB in existing applications?

A: Yes, the YB15CKW01-FB is electrically compatible as a substitute. Both components share identical SPDT circuit configuration, On-Mom switch function, 125V AC and 30V DC voltage ratings, and -25°C to 70°C operating temperature range. The substitute provides enhanced current capacity and extended mechanical and electrical life. Panel cutout diameter and termination style differences require mechanical and electrical evaluation for specific installations.

Q: What are the key differences between these two parts?

A: The primary differences are: current rating (1A vs 3A), mechanical life (100,000 vs 1,000,000 cycles), electrical life (50,000 vs 100,000 cycles), panel cutout diameter (12.30mm vs 16.00mm), termination style (solder lug vs solder with quick connect), and product status (obsolete vs active). The YB15CKW01-FB exceeds the performance specifications of the KB15CKW01-FB across all measurable parameters.

Q: Does the larger panel cutout diameter of the YB15CKW01-FB affect compatibility?

A: The 16.00mm cutout diameter of the YB15CKW01-FB is larger than the 12.30mm diameter of the KB15CKW01-FB. Direct mechanical substitution requires panel modification to accommodate the larger diameter. Verify panel material and structural integrity before enlarging the cutout.

Q: Are both parts RoHS compliant?

A: Yes, both the KB15CKW01-FB and YB15CKW01-FB are ROHS3 compliant, meeting current environmental and hazardous substance restrictions.

Q: What termination options are available?

A: The KB15CKW01-FB uses solder lug termination. The YB15CKW01-FB offers solder termination with quick connect 0.110" (2.8mm) options, providing alternative connection methods for circuit board integration.

Q: Is the YB15CKW01-FB available for new designs?

A: Yes, the YB15CKW01-FB maintains active product status with current manufacturing availability, making it suitable for new design implementations and replacement of obsolete KB15CKW01-FB components.
