KB15CKG01-05-JC Equivalent & Substitute Parts

Part Overview

The KB15CKG01-05-JC is an illuminated pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry with incandescent red illumination. This component is rated for 0.4VA at 28V AC/DC and is designed for panel-mounted front installation with a 12.30mm circular cutout. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15CKG01-05-JC is determined by the following critical parameters:

• Circuit Configuration: SPDT topology must be maintained for electrical compatibility
• Voltage Rating: 28V AC/DC operation is mandatory
• Current Rating: 0.4VA minimum capacity required
• Switch Function: On-Mom (momentary) operation must be preserved
• Mounting Type: Panel mount, front installation configuration
• Illumination: Red indicator light functionality
• Operating Temperature: -25°C to +50°C range compatibility
• Termination Style: Connection method must support system integration

The YB15CKG01-5C05-JC qualifies as a substitute based on matching these core electrical and mechanical parameters. Differences in panel cutout diameter, illumination technology (LED vs. incandescent), illumination voltage specification (5 VDC vs. 5 VAC), mechanical life rating, and termination connector type represent design variations that do not prevent functional substitution when system constraints permit.

Parameter Comparison

Engineering Selection Recommendations

The YB15CKG01-5C05-JC is an active-status substitute for the obsolete KB15CKG01-05-JC. Both components maintain identical electrical specifications for circuit configuration, voltage rating, current capacity, and switch function. The substitute offers extended mechanical life (1,000,000 cycles vs. 100,000 cycles), providing improved durability for high-cycle applications.

Selection considerations based on provided specifications:

Mechanical Integration: The substitute requires a 16.00mm panel cutout diameter compared to the original 12.30mm specification. Panel modification or adapter mounting may be necessary depending on existing installation geometry.

Illumination Technology: The substitute employs LED illumination (5 VDC) in place of incandescent illumination (5 VAC). Verification of illumination circuit voltage supply compatibility is required before implementation.

Termination Compatibility: The substitute offers dual termination options (Solder and Quick Connect 0.110" connectors) versus the original solder lug configuration. System wiring and connector compatibility must be evaluated.

Compliance Status: Both components meet MSL 1 (Unlimited) moisture sensitivity requirements. RoHS3 compliance is confirmed for the main part; compliance status for the substitute is not specified in available documentation.

Frequently Asked Questions (FAQ)

Q: Can the YB15CKG01-5C05-JC directly replace the KB15CKG01-05-JC without modifications?

A: Direct replacement requires verification of three factors: panel cutout diameter compatibility (16.00mm vs. 12.30mm), illumination voltage supply (5 VDC vs. 5 VAC), and termination connector type (Quick Connect vs. Solder Lug). Mechanical and electrical integration assessment is necessary.

Q: What are the core electrical parameters that define substitution eligibility?

A: Substitution is based on matching SPDT circuit configuration, 28V AC/DC voltage rating, 0.4VA current capacity, On-Mom switch function, and -25°C to +50°C operating temperature range. These parameters ensure functional compatibility within the electrical system.

Q: Does the LED illumination in the substitute affect system performance?

A: LED illumination provides equivalent red indicator functionality with extended operational life compared to incandescent technology. The primary difference is illumination voltage specification: the substitute requires 5 VDC supply versus the original 5 VAC requirement. Circuit voltage compatibility must be confirmed.

Q: What is the significance of the 1,000,000-cycle mechanical life rating in the substitute?

A: The substitute's extended mechanical life (1,000,000 cycles vs. 100,000 cycles) indicates improved durability for applications requiring frequent switch actuation. This represents a design enhancement over the original component.

Q: Are there panel installation constraints with the larger cutout diameter?

A: The substitute requires a 16.00mm circular cutout compared to the original 12.30mm specification. Existing panel installations designed for the original component may require enlargement of the mounting aperture or use of adapter hardware.

Q: What termination options are available with the substitute?

A: The YB15CKG01-5C05-JC provides both Solder and Quick Connect (0.110" / 2.8mm) termination options, offering flexibility for different wiring integration methods. The original component features Solder Lug termination only.
