KB15RKW01B Equivalent & Substitute Parts

Part Overview

The KB15RKW01B is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 1A current rating at 125V AC and 30V DC. This component is designed for standard panel mount, front installation applications with solder lug termination. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15RKW01B is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-Mom (momentary operation)
• Voltage rating: 125V AC minimum
• Mounting type: Panel Mount, Front
• Operating temperature range: -25°C to 70°C minimum

Allowable Variation Parameters:

• Current rating: May exceed 1A (higher current capacity is acceptable for lower-current applications)
• Mechanical and electrical life: May exceed specified cycles (higher durability is acceptable)
• Panel cutout diameter: Variation acceptable if mechanical installation can be accommodated
• Termination style: Variation acceptable if electrical connection requirements are met
• Product status: Active status preferred for ongoing availability

The YB15RKW01 meets all mandatory matching parameters while providing enhanced specifications in current rating (3A), mechanical life (1,000,000 cycles), and electrical life (100,000 cycles).

Parameter Comparison

Engineering Selection Recommendations

The YB15RKW01 is a direct functional equivalent for KB15RKW01B applications. Both components are ROHS3 compliant and maintain identical voltage and temperature specifications. The YB15RKW01 offers superior reliability through extended mechanical and electrical life ratings, making it suitable for replacement in existing designs.

The primary design consideration is panel cutout diameter: the YB15RKW01 requires a 16.00mm circular opening compared to the KB15RKW01B's 12.30mm opening. Panel modifications may be necessary for mechanical installation. Termination style differs between solder lug (KB15RKW01B) and solder with quick connect option (YB15RKW01), requiring evaluation of circuit board layout and connection methodology.

The active product status of YB15RKW01 ensures long-term availability and supply chain continuity compared to the obsolete KB15RKW01B.

Frequently Asked Questions (FAQ)

Q: Can YB15RKW01 directly replace KB15RKW01B in all applications?

A: Electrical compatibility is confirmed across all voltage, current, and circuit specifications. Mechanical compatibility requires panel cutout diameter verification. The YB15RKW01 requires a 16.00mm opening versus the KB15RKW01B's 12.30mm opening. Termination style differences (solder lug versus solder with quick connect) must be evaluated for your specific circuit board design.

Q: What are the key differences between these parts?

A: Current rating increases from 1A to 3A. Mechanical life extends from 100,000 to 1,000,000 cycles. Electrical life doubles from 50,000 to 100,000 cycles. Panel cutout diameter increases from 12.30mm to 16.00mm. Termination options expand from solder lug only to solder with quick connect capability.

Q: Is the higher current rating of YB15RKW01 suitable for 1A applications?

A: Yes. A 3A-rated component operates safely in 1A circuits. Higher current capacity does not affect performance in lower-current applications.

Q: What compliance certifications apply to both parts?

A: Both KB15RKW01B and YB15RKW01 are ROHS3 compliant and REACH unaffected. Both carry EAR99 ECCN classification and identical HTSUS code 8536.50.9031.

Q: Why is product status relevant for component selection?

A: KB15RKW01B is classified as obsolete, indicating discontinued manufacturing and potential supply constraints. YB15RKW01 maintains active status, ensuring availability for current and future procurement requirements.
