KB25CKW01-GG Equivalent & Substitute Parts

Part Overview

The KB25CKW01-GG is a pushbutton switch manufactured by NKK Switches, featuring DPDT (Double Pole Double Throw) circuit configuration with On-Momentary switch function. This component is rated for 1A at 125V AC and 30V DC, with a circular 12.30mm panel cutout for front-mounted installation. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing maintenance, repair, and redesign applications where this component is specified in legacy systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB25CKW01-GG is determined by the following critical parameters that must remain compatible:

Mandatory Compatibility Parameters:

• Circuit configuration: DPDT
• Switch function: On-Momentary
• Voltage rating: 125V AC minimum
• Mounting type: Panel Mount, Front
• Actuator type: Round Button
• Operating temperature range: -25°C to 70°C minimum

Allowable Variation Parameters:

• Current rating: May exceed 1A (higher current rating is backward compatible)
• Mechanical and electrical life: May exceed specified cycles
• Termination style: May differ if electrical connection is maintained
• Panel cutout diameter: May differ if mechanical adaptation is feasible
• RoHS and regulatory compliance: Must maintain or exceed existing certifications

The YB25WCKW01-GB meets all mandatory compatibility parameters while exceeding performance specifications in current rating, mechanical life, and electrical life. This substitution is valid for applications where the KB25CKW01-GG is specified.

Parameter Comparison

Engineering Selection Recommendations

The YB25WCKW01-GB is a valid substitute for the KB25CKW01-GG based on the following engineering criteria:

Functional Equivalence: Both components share identical circuit configuration (DPDT), switch function (On-Momentary), voltage ratings (125V AC / 30V DC), and operating temperature range (-25°C to 70°C). The YB25WCKW01-GB exceeds the current rating specification at 3A versus 1A, providing enhanced capability for higher-load applications.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring continued compliance with environmental and hazardous substance regulations.

Product Status Advantage: The YB25WCKW01-GB is currently active in production, whereas the KB25CKW01-GG is obsolete. Selection of the active substitute ensures long-term availability and supply chain continuity.

Performance Enhancement: The substitute provides superior mechanical life (1,000,000 cycles versus 100,000 cycles) and electrical life (100,000 cycles versus 50,000 cycles), extending component reliability in cyclic applications.

Mechanical Considerations: The panel cutout diameter increases from 12.30mm to 16.00mm. Panel modifications may be required for direct mechanical replacement. Termination style changes from Solder Lug to Solder with Quick Connect options, requiring electrical connection adaptation.

Frequently Asked Questions (FAQ)

Q: Can the YB25WCKW01-GB directly replace the KB25CKW01-GG without any modifications?

A: Electrical substitution is valid. Mechanical panel cutout diameter differs (12.30mm versus 16.00mm), requiring panel modification or adapter consideration. Termination style differs, requiring connection method adjustment from solder lug to solder or quick connect terminals.

Q: What is the significance of the higher current rating (3A) on the substitute part?

A: The YB25WCKW01-GB's 3A rating is backward compatible with the KB25CKW01-GG's 1A specification. Applications drawing 1A or less operate safely within the substitute's rated capacity. Higher current rating provides design margin and supports potential future application requirements without component change.

Q: Are there any compliance or certification differences between these parts?

A: Both components maintain identical RoHS3 compliance and REACH unaffected status. No compliance disadvantage exists with the substitute selection.

Q: Why does the substitute have a larger panel cutout diameter?

A: The YB25WCKW01-GB's 16.00mm cutout reflects design improvements in the YB series. Panel adaptation is necessary for mechanical fit in applications designed for the 12.30mm KB series cutout.

Q: What is the advantage of the IP65 rating on the substitute?

A: The YB25WCKW01-GB provides IP65 ingress protection (dust tight, water resistant), whereas the KB25CKW01-GG does not specify ingress protection. This enhancement benefits applications requiring environmental sealing without additional component modifications.

Q: Is the substitute suitable for legacy system repairs?

A: Yes. The YB25WCKW01-GB provides functional electrical equivalence for legacy KB25CKW01-GG applications. Mechanical panel modifications and termination connection adaptation are required. The active product status ensures availability for ongoing maintenance and repair operations.
