KB15RKG01 Equivalent & Substitute Parts

Part Overview

The KB15RKG01 is a pushbutton switch manufactured by NKK Switches, configured as a Standard Panel Mount SPDT (Single Pole Double Throw) switch with On-Momentary function. This component is rated for 0.4VA at 28V AC/DC operation with a circular 12.30mm panel cutout. The KB15RKG01 is classified as Obsolete, making identification of equivalent substitute parts essential for ongoing system maintenance and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB15RKG01 is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPDT topology must be maintained
• Switch Function: On-Momentary operation required
• Electrical Ratings: 0.4VA at 28V AC/DC minimum
• Mounting Configuration: Panel Mount, Front orientation
• Actuator Type: Plunger for Cap design
• Operating Temperature: -25°C to 70°C range
• Compliance: ROHS3 and REACH compliance required

The YB15RKG01 qualifies as a substitute part based on matching all critical electrical and mechanical parameters. Differences in panel cutout diameter (16.00mm vs 12.30mm), termination style (Quick Connect vs Solder Lug), and mechanical life rating (1,000,000 vs 100,000 cycles) represent design enhancements rather than functional incompatibilities, provided panel mounting geometry can be accommodated in the target application.

Parameter Comparison

Engineering Selection Recommendations

The YB15RKG01 is the qualified substitute for KB15RKG01 applications. Both components maintain identical electrical specifications (SPDT, On-Momentary, 0.4VA at 28V AC/DC) and comply with ROHS3 and REACH requirements. The YB15RKG01 is currently in Active product status with 1,033 units available in inventory, whereas the KB15RKG01 is Obsolete with limited remaining stock.

Selection of YB15RKG01 requires verification that the larger panel cutout diameter (16.00mm vs 12.30mm) is compatible with the target panel geometry. The alternative termination style (Quick Connect vs Solder Lug) must be evaluated against existing circuit board connection methods. The enhanced mechanical life rating (1,000,000 cycles) of the YB15RKG01 provides extended operational durability compared to the original specification.

Frequently Asked Questions (FAQ)

Q: Can YB15RKG01 directly replace KB15RKG01 in existing designs?

A: Electrical compatibility is confirmed across all critical parameters. Physical compatibility depends on panel cutout accommodation. The 16.00mm cutout of YB15RKG01 requires a larger opening than the 12.30mm specification of KB15RKG01. Termination style differences (Quick Connect vs Solder Lug) must be evaluated against circuit board connection capabilities.

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

A: Both switches share identical SPDT circuit configuration, On-Momentary function, 0.4VA rating at 28V AC/DC, and operating temperature range. Differences include panel cutout diameter, termination method, mechanical life rating, and product status. The YB15RKG01 offers enhanced mechanical durability and is currently in active production.

Q: Are both parts compliant with current regulations?

A: Both KB15RKG01 and YB15RKG01 are ROHS3 Compliant and REACH Unaffected. Both carry EAR99 ECCN classification and identical HTSUS code 8536.50.9031.

Q: What is the impact of the different panel cutout sizes?

A: The KB15RKG01 requires a 12.30mm circular panel opening, while YB15RKG01 requires 16.00mm. Substitution is feasible only if the panel can accommodate the larger opening or if panel modification is acceptable for the application.

Q: Does the termination style difference affect electrical performance?

A: Both Solder Lug and Quick Connect termination styles provide equivalent electrical connectivity. Selection depends on circuit board design and assembly process compatibility. Quick Connect termination may offer faster assembly but requires compatible receptacles.
