Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB15CKW01-CB is determined by strict compatibility across the following electrical and mechanical parameters:

Mandatory Matching Parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom momentary operation)
• Voltage ratings (125V AC minimum, 30V DC)
• Mounting type (Panel Mount, Front)
• Actuator type (Round, Button)
• Operating temperature range (-25°C to 70°C minimum)
• RoHS3 compliance status

Allowable Variation Parameters:

• Current rating (substitute must meet or exceed 1A requirement)
• Panel cutout diameter (mechanical accommodation required)
• Termination style (electrical compatibility with circuit board design)
• Mechanical and electrical life cycles (higher ratings acceptable)
• Series designation (different series acceptable if all electrical/mechanical parameters align)

The YB15CKW01-CB qualifies as a substitute based on matching all mandatory parameters while exceeding performance specifications in current rating (3A vs. 1A), mechanical life (1,000,000 vs. 100,000 cycles), and electrical life (100,000 vs. 50,000 cycles).

Parameter Comparison

Engineering Selection Recommendations

The YB15CKW01-CB is the designated substitute for the obsolete KB15CKW01-CB. Both components maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), ensuring regulatory and environmental compatibility.

Key Considerations:

The substitute part exceeds the original specifications in current-carrying capacity (3A vs. 1A) and operational durability (1,000,000 mechanical cycles vs. 100,000), providing enhanced reliability for the same electrical function. The active product status of YB15CKW01-CB ensures ongoing availability and supply chain continuity.

Panel cutout diameter increases from 12.30mm to 16.00mm, requiring mechanical accommodation in the mounting panel. Termination options expand from solder lug only to include quick connect terminals (0.110" / 2.8mm), offering installation flexibility while maintaining solder lug compatibility.

Both components are classified as EAR99 under export control and share identical HTSUS coding (8536.50.9031), confirming functional and regulatory equivalence.

Frequently Asked Questions (FAQ)

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

A: Electrical substitution is direct. The larger panel cutout diameter (16.00mm vs. 12.30mm) requires panel modification or use of a larger mounting bezel. Termination compatibility depends on circuit board design; both solder lug and quick connect options are available on the substitute.

Q: What is the impact of the increased current rating (3A vs. 1A)?

A: The substitute part is rated for three times the current capacity. This provides design margin and does not create compatibility issues in circuits designed for 1A operation. No circuit modifications are required.

Q: Are there differences in mechanical durability?

A: The YB15CKW01-CB provides 10 times greater mechanical life (1,000,000 vs. 100,000 cycles) and double the electrical life (100,000 vs. 50,000 cycles). This represents improved component longevity with no negative impact on the original application.

Q: How does the termination style difference affect installation?

A: The KB15CKW01-CB uses solder lug termination exclusively. The YB15CKW01-CB offers both solder and quick connect (0.110" / 2.8mm) options. Solder lug compatibility is maintained; quick connect terminals provide alternative installation methods if circuit board design permits.

Q: Are compliance certifications equivalent?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99. MSL ratings are identical (1 - Unlimited). Regulatory and environmental compliance is fully equivalent.

Q: What is the significance of the product status change from Obsolete to Active?

A: The substitute part's active status ensures continued manufacturing, availability, and technical support from NKK Switches. This eliminates supply chain risk associated with obsolete component sourcing.
