KB15CKG01 Equivalent & Substitute Parts

Part Overview

The KB15CKG01 is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 0.4VA current rating at 28V AC/DC. This component is designed for panel-mount front installation with a plunger actuator and solder lug termination. The product is currently classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15CKG01 is determined by the following critical parameters:

• Circuit Configuration: Must be SPDT to maintain electrical functionality
• Switch Function: Must be On-Mom (momentary) operation
• Current Rating: Must support minimum 0.4VA at rated voltage
• Voltage Rating: Must support 28V AC and 28V DC operation
• Mounting Type: Must be Panel Mount, Front configuration
• Actuator Type: Must be Plunger for Cap design
• Operating Temperature Range: Must encompass -25°C to 70°C minimum
• Compliance: Must maintain ROHS3 and REACH compliance status

The YB15CKG01 meets all mandatory substitution criteria. While differences exist in panel cutout diameter (16.00mm vs 12.30mm), mechanical life rating (1,000,000 vs 100,000 cycles), and termination style (Solder/Quick Connect vs Solder Lug), the core electrical and functional parameters remain compatible for equivalent operation in applications designed for the KB15CKG01.

Parameter Comparison

Engineering Selection Recommendations

The YB15CKG01 is the qualified substitute for KB15CKG01 applications. Selection is supported by:

• Electrical Equivalence: Identical circuit configuration (SPDT), current rating (0.4VA), and voltage specifications (28V AC/DC) ensure functional compatibility in existing circuit designs
• Compliance Continuity: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for the same application domains
• Active Product Status: The YB15CKG01 is currently in active production, providing supply continuity for the obsolete KB15CKG01
• Mechanical Compatibility: Panel mount front installation and plunger actuator design maintain mechanical interface compatibility with existing panel assemblies

Design integration requires evaluation of termination style differences (Solder Lug vs Solder/Quick Connect) and panel cutout diameter accommodation (12.30mm vs 16.00mm) for specific installation requirements.

Frequently Asked Questions (FAQ)

Q: Can YB15CKG01 directly replace KB15CKG01 in existing designs?

A: Electrical and functional compatibility is confirmed. Physical integration requires verification of panel cutout diameter (16.00mm for YB15CKG01 vs 12.30mm for KB15CKG01) and termination style compatibility (Quick Connect option available on YB15CKG01).

Q: What are the key differences between these parts?

A: Primary differences include panel cutout diameter, mechanical life rating (1,000,000 vs 100,000 cycles), and termination options. Electrical specifications, voltage ratings, current capacity, and operating temperature range are identical.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both KB15CKG01 and YB15CKG01 are ROHS3 compliant and REACH unaffected, maintaining compliance for regulated applications.

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

A: The YB15CKG01 requires a 16.00mm circular cutout versus 12.30mm for the KB15CKG01. Panel modifications or adapter solutions may be necessary for direct mechanical substitution in existing assemblies.

Q: Does the higher mechanical life rating of YB15CKG01 affect compatibility?

A: No. The 1,000,000-cycle mechanical life of YB15CKG01 exceeds the 100,000-cycle requirement of KB15CKG01, providing enhanced durability without affecting electrical or functional compatibility.

Q: What termination options are available for the substitute part?

A: YB15CKG01 offers both Solder and Quick Connect (0.110" / 2.8mm) termination styles, providing flexibility beyond the Solder Lug termination of KB15CKG01.
