KB15RKW01 Equivalent & Substitute Parts

Part Overview

The KB15RKW01 is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 1A current rating at 125V AC. This component is designed for standard panel mount applications with front-facing actuator orientation. The product is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15RKW01 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit Configuration: SPDT
• Switch Function: On-Mom (Momentary)
• Voltage Rating - AC: 125V
• Voltage Rating - DC: 30V
• Mounting Type: Panel Mount, Front
• Actuator Type: Plunger for Cap
• Operating Temperature Range: -25°C ~ 70°C
• RoHS Compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Current Rating: May exceed 1A (higher current rating is acceptable for backward compatibility)
• Mechanical Life: May exceed 100,000 cycles
• Electrical Life: May exceed 50,000 cycles
• Termination Style: May differ if mechanical and electrical compatibility is maintained
• Panel Cutout Dimensions: May differ if mechanical mounting accommodation is feasible
• Product Status: Active status preferred for ongoing availability

The YB15RKW01 meets all mandatory matching parameters while exceeding performance 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 the designated substitute for the obsolete KB15RKW01. Both components maintain identical electrical specifications for voltage and circuit configuration while the YB15RKW01 provides enhanced performance characteristics. The substitute part carries Active product status, ensuring continued availability and supply chain reliability.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing standards. The YB15RKW01 demonstrates superior mechanical and electrical life ratings, providing extended operational durability compared to the original KB15RKW01 specification.

Physical integration requires consideration of panel cutout dimension differences: the KB15RKW01 requires a 12.30mm circular cutout while the YB15RKW01 requires a 16.00mm circular cutout. Termination style differences (Solder Lug versus Solder with Quick Connect option) must be evaluated against existing circuit board design and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the YB15RKW01 directly replace the KB15RKW01 in existing designs?

A: Electrical substitution is valid based on matching SPDT circuit configuration, On-Mom function, and identical voltage ratings (125V AC / 30V DC). Physical integration requires panel cutout modification from 12.30mm to 16.00mm diameter and termination style accommodation.

Q: What are the key differences between KB15RKW01 and YB15RKW01?

A: The YB15RKW01 provides higher current capacity (3A versus 1A), extended mechanical life (1,000,000 versus 100,000 cycles), and extended electrical life (100,000 versus 50,000 cycles). The substitute features active product status and includes tactile feedback. Panel cutout dimensions and termination options differ between the two parts.

Q: Are both parts RoHS compliant?

A: Yes, both KB15RKW01 and YB15RKW01 are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing.

Q: What is the significance of the KB15RKW01 obsolete status?

A: Obsolete classification indicates the KB15RKW01 is no longer manufactured or supported by NKK Switches. The YB15RKW01 active status ensures ongoing availability, technical support, and supply chain continuity for new implementations and replacement requirements.

Q: How do termination style differences affect circuit board integration?

A: The KB15RKW01 uses Solder Lug termination while the YB15RKW01 offers Solder with Quick Connect - 0.110" (2.8mm) options. Circuit board design must accommodate the appropriate termination method during PCB layout and assembly planning.

Q: What operating temperature range applies to both parts?

A: Both the KB15RKW01 and YB15RKW01 operate within the -25°C to 70°C temperature range, providing identical thermal performance specifications for environmental application requirements.
