KB26CKG01 Equivalent & Substitute Parts Reference

Part Overview

The KB26CKG01 is a pushbutton switch manufactured by NKK Switches, configured as a DPDT (Double Pole Double Throw) standard panel mount component with a 0.4VA current rating at 28V AC/DC. This part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The KB26CKG01 features a plunger actuator with solder lug termination and a 12.30mm circular panel cutout, designed for applications requiring reliable switching at low voltage levels with mechanical and electrical life ratings of 100,000 cycles.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB26CKG01 is determined by strict alignment across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration (DPDT)
• Switch function (On-On)
• Current rating (0.4VA AC/DC)
• Voltage rating (28V AC/DC)
• Mounting type (Panel Mount, Front)
• Actuator type (Plunger for Cap)
• Operating temperature range (-25°C to 70°C)
• RoHS compliance status (ROHS3 Compliant)

Allowable Variations:

• Termination style (Solder Lug vs. Solder Quick Connect)
• Panel cutout dimensions (mechanical accommodation required)
• Mechanical and electrical life ratings (equal or greater values acceptable)
• Product status (Active status preferred for obsolete parts)
• Packaging format (Bulk vs. standard)

The YB26CKG01 qualifies as a substitute based on matching all mandatory parameters while offering enhanced mechanical life (200,000 cycles vs. 100,000 cycles) and active product status.

Parameter Comparison

Engineering Selection Recommendations

The YB26CKG01 serves as the active equivalent for the obsolete KB26CKG01. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and legacy system replacements.

Selection of YB26CKG01 over KB26CKG01 is supported by:

• Active manufacturing status, ensuring long-term availability and supply chain stability
• Doubled mechanical life rating (200,000 cycles), providing extended operational durability
• Identical electrical specifications and circuit configuration, guaranteeing functional compatibility
• Enhanced reliability through current production quality standards

Implementation of YB26CKG01 requires mechanical and electrical design verification:

• Panel cutout diameter increases from 12.30mm to 16.00mm; panel modification or adapter mounting may be necessary
• Termination transition from solder lug to quick connect 0.110" (2.8mm) requires circuit board layout adjustment and connector compatibility confirmation

Frequently Asked Questions (FAQ)

Q: Can YB26CKG01 directly replace KB26CKG01 without design modifications?

A: Electrical and functional compatibility is complete. Mechanical integration requires panel cutout diameter accommodation (12.30mm to 16.00mm) and termination style transition (solder lug to quick connect). Circuit board layout and panel design must be evaluated for compatibility.

Q: What are the key differences between KB26CKG01 and YB26CKG01?

A: The primary differences are product status (obsolete vs. active), mechanical life rating (100,000 vs. 200,000 cycles), panel cutout diameter (12.30mm vs. 16.00mm), and termination style (solder lug vs. quick connect 0.110"). All electrical parameters and circuit configurations remain identical.

Q: Is YB26CKG01 suitable for applications originally designed for KB26CKG01?

A: Yes, provided mechanical integration is addressed. The YB26CKG01 meets or exceeds all electrical and environmental specifications of the KB26CKG01, with improved mechanical durability. Panel cutout and termination compatibility must be confirmed for the specific application.

Q: What compliance certifications apply to both parts?

A: Both KB26CKG01 and YB26CKG01 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: Are there packaging differences between these parts?

A: KB26CKG01 is supplied in standard packaging, while YB26CKG01 is available in bulk packaging. This distinction does not affect electrical or mechanical performance.
