KB25CKG01-EB Equivalent & Substitute Parts

Part Overview

The KB25CKG01-EB is a pushbutton switch manufactured by NKK Switches, featuring DPDT (Double Pole Double Throw) circuitry with On-Momentary switch function. This component is rated for 0.4VA at 28V AC/DC and is designed for standard panel mount, front installation with a circular 12.30mm diameter cutout. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB25CKG01-EB is determined by the following critical parameters:

• Circuit configuration (DPDT required)
• Switch function (On-Momentary operation)
• Electrical ratings (0.4VA at 28V AC/DC minimum)
• Actuator type (Round button)
• Mounting configuration (Panel mount, front)
• Operating temperature range (-25°C to 70°C)
• Compliance certifications (RoHS3, REACH status)

The YB25CKG01-EB qualifies as a substitute based on matching all core electrical and functional parameters. However, mechanical differences exist in panel cutout dimensions, termination style, and lifecycle ratings that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The YB25CKG01-EB is functionally equivalent to the KB25CKG01-EB for applications requiring DPDT pushbutton switch operation at 28V with 0.4VA current capacity. The substitute part offers the advantage of active product status, ensuring continued availability and supply chain reliability.

Key considerations for selection:

• Panel cutout diameter differs (12.30mm vs. 16.00mm). Panel modifications may be required if retrofitting into existing enclosures designed for the KB25CKG01-EB.
• Termination style differs (Solder Lug vs. Solder/Quick Connect). Wiring harness compatibility must be evaluated based on existing connection infrastructure.
• Mechanical life rating is significantly higher on the YB25CKG01-EB (1,000,000 vs. 100,000 cycles), providing extended operational durability.
• Both parts maintain identical electrical ratings, operating temperature range, and moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can the YB25CKG01-EB directly replace the KB25CKG01-EB in existing assemblies?

A: Electrical and functional compatibility is confirmed. Physical installation compatibility depends on panel cutout dimensions and termination connection type. Panel cutout diameter increases from 12.30mm to 16.00mm, and termination changes from Solder Lug to Solder/Quick Connect. Mechanical and electrical modifications may be necessary.

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

A: DPDT circuit configuration, On-Momentary switch function, 0.4VA current rating at 28V AC/DC, round button actuator type, panel mount front installation, and -25°C to 70°C operating temperature range must all be maintained for functional equivalence.

Q: Why is the KB25CKG01-EB classified as obsolete?

A: Product status reflects manufacturer discontinuation. The YB25CKG01-EB represents the active equivalent offering from NKK Switches for this switch category.

Q: Are there compliance differences between these parts?

A: The KB25CKG01-EB is confirmed ROHS3 compliant. RoHS status for the YB25CKG01-EB is not specified in available documentation. Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification.

Q: What is the impact of the higher mechanical life rating on the substitute part?

A: The YB25CKG01-EB mechanical life rating of 1,000,000 cycles versus 100,000 cycles on the original part indicates extended component durability and reduced replacement frequency in high-cycle applications.
