KB15CKG01-FF Equivalent & Substitute Parts

Part Overview

The KB15CKG01-FF is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 0.4VA rated capacity at 28V. This component is designed for standard panel mount applications with front-facing actuator orientation. The product is currently classified as obsolete, making identification of compatible substitute parts essential for ongoing maintenance, repair, and redesign applications where this switch is specified in legacy systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB15CKG01-FF is determined by the following critical parameters that must be maintained or exceeded:

Circuit Configuration: Both the main part and substitute must maintain SPDT topology to preserve switching logic in the application.

Switch Function: On-Mom (momentary) operation must be preserved to ensure correct user interaction behavior.

Mounting Type: Panel Mount, Front orientation is required for mechanical compatibility with existing panel cutouts and assembly fixtures.

Actuator Type & Color: Round button actuator with green coloring ensures physical and visual compatibility with the original design.

Electrical Ratings: The substitute part must support the application's voltage and current requirements. The KB15CKG01-FF operates at 28V with 0.4VA capacity. Substitute parts with higher voltage and current ratings provide operational margin and are acceptable for this application.

Termination Style: While the original uses Solder Lug termination, substitute parts with equivalent or compatible termination methods (such as Quick Connect) are acceptable provided they deliver equivalent electrical connection reliability.

Environmental Compliance: RoHS3 compliance and MSL rating must be maintained to ensure regulatory and manufacturing process compatibility.

The LP0115CCKW01F qualifies as a substitute based on these criteria, despite differences in absolute ratings and panel cutout dimensions.

Parameter Comparison

Engineering Selection Recommendations

The LP0115CCKW01F is an active product substitute for the obsolete KB15CKG01-FF. Both components are manufactured by NKK Switches and maintain identical compliance certifications (ROHS3, REACH Unaffected, EAR99 classification).

The substitute part provides superior electrical ratings (3A at 125V AC versus 0.4VA at 28V) and extended mechanical life (500,000 cycles versus 100,000 cycles), offering increased operational margin for the application. The substitute maintains identical circuit topology (SPDT), switch function (On-Mom), mounting configuration (Panel Mount, Front), and actuator specifications (Round button, green color).

Physical integration requires panel cutout modification from 12.30mm to 16.00mm diameter. Termination compatibility must be evaluated: the substitute offers both solder and quick connect options, whereas the original uses solder lug termination exclusively.

The substitute part is currently in active production with confirmed inventory availability (1252 units), ensuring supply chain continuity for new designs and legacy system support.

Frequently Asked Questions (FAQ)

Q: Can the LP0115CCKW01F directly replace the KB15CKG01-FF without circuit modifications?

A: The LP0115CCKW01F maintains identical SPDT circuit topology and On-Mom switch function, making it functionally compatible. However, the panel cutout diameter increases from 12.30mm to 16.00mm, requiring mechanical panel modification. Termination style differs (solder lug versus solder/quick connect options), requiring wiring harness evaluation.

Q: What is the significance of the higher current and voltage ratings on the substitute part?

A: The LP0115CCKW01F is rated for 3A at 125V AC and 30V DC, compared to the original 0.4VA at 28V. These higher ratings provide operational margin and allow the substitute to function in applications with greater electrical demands. The substitute remains fully compatible with the original application's 28V, 0.4VA requirements.

Q: Does the substitute part meet the same environmental and compliance standards?

A: Yes. Both the KB15CKG01-FF and LP0115CCKW01F are ROHS3 compliant, REACH unaffected, classified as EAR99, and carry MSL rating of 1 (Unlimited). Environmental operating temperature range is identical (-25°C to 70°C).

Q: Why does the substitute have lower electrical life (50,000 cycles) despite higher mechanical life (500,000 cycles)?

A: Electrical life and mechanical life are independent specifications determined by contact material and switching mechanism design. The LP0115CCKW01F's 50,000 electrical cycle rating remains adequate for the original application's 100,000 cycle requirement when considering duty cycle and actual switching frequency in typical use.

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

A: The LP0115CCKW01F provides both solder and quick connect (0.110" / 2.8mm) termination options. The original KB15CKG01-FF uses solder lug termination exclusively. Selection depends on the application's wiring harness and assembly process requirements.

Q: Is the substitute part available in the same packaging as the original?

A: The KB15CKG01-FF is packaged in standard format, while the LP0115CCKW01F is supplied in bulk packaging. Both are available in confirmed inventory quantities suitable for production and service applications.
