KB15CKG01-12-FF Equivalent & Substitute Parts

Part Overview

The KB15CKG01-12-FF is an illuminated pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry with a 0.4VA current rating at 28V. This panel-mount component is designed for front installation with a green incandescent illumination system operating at 12VAC. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and redesign applications where continued functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB15CKG01-12-FF is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must remain SPDT
• Current rating must support minimum 0.4VA at 28V (AC/DC)
• Voltage rating must equal or exceed 28V AC/DC
• Switch function must maintain On-Momentary operation

Mechanical & Installation Requirements:

• Mounting type must be Panel Mount, Front
• Actuator type must be Round Button
• Operating temperature range must encompass -25°C to 50°C
• Mechanical life must meet or exceed 100,000 cycles

Illumination & Functional Requirements:

• Illumination color must be green
• Panel cutout diameter compatibility must be verified
• Termination style compatibility with existing circuit board design

The substitute part YB15CKG01-5F12-JF meets these core electrical and mechanical requirements while introducing design improvements in illumination technology and mechanical durability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement Applications:

The YB15CKG01-5F12-JF serves as the primary substitute for KB15CKG01-12-FF. Both components maintain identical electrical specifications (SPDT, 0.4VA, 28V AC/DC) and mechanical mounting requirements (Panel Mount, Front; Round Button actuator). Both are ROHS3 compliant and operate across the same temperature range (-25°C to 50°C).

Key Considerations for Implementation:

1. Panel Cutout Diameter: The main part requires a 12.30mm circular cutout, while the substitute requires 16.00mm. Physical panel modification may be necessary.

2. Illumination Technology Transition: The main part uses incandescent illumination at 12VAC; the substitute uses LED illumination at 12VDC. Verify that the control circuit can supply 12VDC instead of 12VAC.

3. Termination Compatibility: The main part uses Solder Lug termination; the substitute uses Solder with Quick Connect 0.110" (2.8mm) termination. Circuit board connection points must be compatible with the quick-connect style.

4. Mechanical Life Enhancement: The substitute offers 1,000,000 mechanical cycles versus 100,000 cycles in the original, providing extended service life in high-cycle applications.

5. Product Availability: The substitute is currently Active with 1,000 pieces in stock, whereas the main part is Obsolete with limited availability.

Frequently Asked Questions (FAQ)

Q: Can YB15CKG01-5F12-JF be used as a direct drop-in replacement for KB15CKG01-12-FF?

A: Electrical and functional compatibility is confirmed. However, physical installation requires verification of panel cutout diameter (16.00mm vs. 12.30mm), illumination voltage supply (12VDC vs. 12VAC), and termination style compatibility (Quick Connect vs. Solder Lug).

Q: What is the primary difference in illumination between these two parts?

A: The KB15CKG01-12-FF uses incandescent illumination operating at 12VAC, while the YB15CKG01-5F12-JF uses LED illumination operating at 12VDC. The control circuit must be capable of supplying the appropriate voltage type.

Q: Are both parts RoHS compliant?

A: Yes, both KB15CKG01-12-FF and YB15CKG01-5F12-JF are ROHS3 compliant and REACH unaffected.

Q: What is the significance of the mechanical life difference?

A: The substitute part (YB15CKG01-5F12-JF) offers 1,000,000 mechanical cycles compared to 100,000 cycles in the original. This tenfold increase in durability extends component service life in applications with frequent switch actuation.

Q: Will the panel cutout diameter difference affect installation?

A: Yes. The substitute requires a 16.00mm diameter cutout versus 12.30mm for the original. Existing panel installations designed for the KB15CKG01-12-FF will require physical modification to accommodate the larger diameter of the YB15CKG01-5F12-JF.

Q: Are the termination styles compatible with existing circuit boards?

A: The main part uses Solder Lug termination, while the substitute uses Solder with Quick Connect 0.110" (2.8mm) termination. Circuit board connection points must be evaluated for compatibility with the quick-connect style before implementation.
