KB25CKG01 Equivalent & Substitute Parts

Part Overview

The KB25CKG01 is a pushbutton switch manufactured by NKK Switches, featuring DPDT (Double Pole Double Throw) circuit configuration with 0.4VA current rating at 28V AC/DC. This component is designed for panel mount, front installation applications with a plunger actuator and solder lug termination. The product is currently obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB25CKG01 is determined by strict equivalence across the following critical parameters:

Circuit Configuration: DPDT topology must be maintained to preserve switching functionality across both poles.

Electrical Ratings: Current rating of 0.4VA and voltage ratings of 28V AC/DC are mandatory for safe operation within the original design envelope.

Switch Function: On-Mom (momentary) operation must be preserved to match the original control logic.

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

Actuator Type: Plunger for Cap configuration ensures consistent user interface and mechanical engagement.

Operating Temperature Range: -25°C ~ 70°C establishes the thermal operating envelope for component selection.

The YB25CKG01 qualifies as a substitute part based on equivalence across all critical electrical and mechanical parameters. However, secondary parameter variations exist that require engineering evaluation during implementation.

Engineering Selection Recommendations

The YB25CKG01 is an active product from NKK Switches and represents a viable substitute for the obsolete KB25CKG01 based on electrical and functional equivalence. Both components maintain ROHS3 compliance and identical moisture sensitivity ratings, supporting regulatory continuity in applications requiring these certifications.

Implementation of the YB25CKG01 requires evaluation of the following secondary parameter variations:

Termination Style: The YB25CKG01 provides dual termination options (Solder and Quick Connect - 0.110" 2.8mm) compared to the KB25CKG01 solder lug configuration. Circuit board layout and assembly procedures must accommodate this change.

Panel Cutout Dimensions: The YB25CKG01 requires a 16.00mm diameter circular cutout versus the KB25CKG01 requirement of 12.30mm diameter. Mechanical redesign of panel mounting interfaces is necessary.

Mechanical Life: The YB25CKG01 offers extended mechanical life of 1,000,000 cycles compared to 100,000 cycles for the KB25CKG01, providing enhanced durability for high-cycle applications.

Frequently Asked Questions (FAQ)

Q: Can the YB25CKG01 directly replace the KB25CKG01 without modifications?

A: Electrical substitution is valid based on circuit configuration, voltage ratings, and current ratings. However, mechanical modifications are required due to differences in panel cutout diameter (16.00mm versus 12.30mm) and termination style options. Panel mounting interfaces must be redesigned accordingly.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is determined by equivalence in circuit configuration (DPDT), switch function (On-Mom), current rating (0.4VA AC/DC), voltage ratings (28V AC/DC), mounting type (Panel Mount, Front), actuator type (Plunger for Cap), and operating temperature range (-25°C ~ 70°C).

Q: Does the YB25CKG01 maintain regulatory compliance with the original KB25CKG01?

A: Both components are ROHS3 compliant and carry identical moisture sensitivity levels (MSL 1 - Unlimited), supporting regulatory continuity in applications requiring these certifications.

Q: What is the impact of the different termination styles?

A: The KB25CKG01 uses solder lug termination, while the YB25CKG01 offers solder and quick connect options. Circuit board design and assembly procedures must be evaluated to accommodate the available termination configurations.

Q: How do the mechanical life ratings differ between these components?

A: The KB25CKG01 is rated for 100,000 mechanical cycles, while the YB25CKG01 is rated for 1,000,000 mechanical cycles. The YB25CKG01 provides extended durability for applications requiring higher cycle counts.

Q: Are there packaging differences between these components?

A: The KB25CKG01 is supplied in standard packaging, while the YB25CKG01 is available in bulk packaging. Procurement and inventory management procedures may require adjustment based on packaging format requirements.
