KB15CKG01-5F05-JB Equivalent & Substitute Parts

Part Overview

The KB15CKG01-5F05-JB is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry with illuminated panel mount design. This component operates at 28V AC/DC with a 0.4VA current rating and includes green LED illumination powered at 5VDC. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15CKG01-5F05-JB is determined by the following critical parameters:

• Circuit Configuration: SPDT topology must be maintained
• Electrical Ratings: 28V AC/DC operation and 0.4VA current capacity
• Switch Function: On-Mom (momentary) operation required
• Illumination: Green LED at 5VDC nominal voltage
• Mounting: Panel mount, front configuration
• Operating Temperature: -25°C to 50°C range
• Environmental Compliance: RoHS3 and MSL Level 1 certification

The YB15CKG01-5F05-JB qualifies as a substitute part because it maintains all critical electrical parameters (SPDT circuit, 28V AC/DC, 0.4VA, On-Mom function, green LED illumination at 5VDC) and environmental compliance standards. Mechanical and electrical life specifications differ, and panel cutout dimensions vary, requiring physical installation verification.

Parameter Comparison

Engineering Selection Recommendations

The YB15CKG01-5F05-JB is suitable as a substitute for the obsolete KB15CKG01-5F05-JB based on electrical and functional equivalence. Both parts maintain identical circuit topology, voltage ratings, current capacity, and illumination specifications. The substitute part carries active product status, ensuring continued availability and supply chain reliability.

Key considerations for selection:

• Panel Cutout Compatibility: The YB series requires a 16.00mm diameter circular cutout versus the KB series 12.30mm diameter. Physical panel modification may be necessary.
• Termination Differences: The KB series uses solder lug termination while the YB series provides solder with quick connect 0.110" (2.8mm) options. Wiring harness adaptation may be required.
• Mechanical Life Enhancement: The YB series offers 1,000,000 cycle mechanical life compared to 100,000 cycles in the KB series, providing extended operational durability.
• Compliance Alignment: Both parts maintain ROHS3 compliance and MSL Level 1 certification, supporting regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the YB15CKG01-5F05-JB directly replace the KB15CKG01-5F05-JB without modifications?

A: Electrical and functional replacement is direct. Physical installation requires panel cutout diameter verification (12.30mm for KB versus 16.00mm for YB) and termination style compatibility assessment (solder lug versus solder/quick connect).

Q: Are the electrical specifications identical between these parts?

A: Yes. Both parts operate at 28V AC/DC with 0.4VA current rating, feature SPDT circuitry with On-Mom function, and include green LED illumination at 5VDC nominal voltage.

Q: What is the significance of the different mechanical life ratings?

A: The KB series is rated for 100,000 mechanical cycles while the YB series is rated for 1,000,000 cycles. This difference reflects design improvements in the active YB series and does not affect electrical compatibility.

Q: Does the panel cutout size difference affect electrical performance?

A: No. The panel cutout dimension is a mechanical installation parameter only and does not impact electrical operation or signal integrity.

Q: Are both parts compliant with current environmental standards?

A: Yes. Both the KB15CKG01-5F05-JB and YB15CKG01-5F05-JB are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.

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

A: The YB15CKG01-5F05-JB provides solder termination with quick connect 0.110" (2.8mm) options, offering flexibility compared to the KB series solder lug configuration.
