KB26CKW01-EB Equivalent & Substitute Parts

Part Overview

The KB26CKW01-EB is a pushbutton switch manufactured by NKK Switches, configured as a DPDT (Double Pole Double Throw) standard panel mount component with On-On switching function. This part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The original specification supports 1A current rating at 125V AC / 30V DC with a yellow actuator and solder lug termination.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB26CKW01-EB is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: DPDT
• Switch function: On-On
• Mounting type: Panel Mount, Front
• Actuator type: Round, Button
• Voltage rating: 125V AC minimum / 30V DC minimum
• Operating temperature range: -25°C to 70°C minimum
• RoHS compliance status

Allowable Variations:

• Current rating: May exceed 1A (higher current capability is acceptable for direct substitution)
• Mechanical and electrical life: May exceed specified values
• Termination style: May differ if mechanical and electrical compatibility is maintained
• Panel cutout diameter: May vary within mechanical design constraints

The YB26CKW01-EB meets all mandatory matching criteria while exceeding performance specifications in current rating (3A), mechanical life (200,000 cycles), and electrical life (100,000 cycles). However, termination style differs (Solder, Quick Connect vs. Solder Lug) and panel cutout diameter is larger (16.00mm vs. 12.30mm), requiring mechanical design verification.

Parameter Comparison

Engineering Selection Recommendations

The YB26CKW01-EB is functionally equivalent to the KB26CKW01-EB for DPDT On-On switching applications within the specified voltage and temperature parameters. The substitute part offers enhanced performance characteristics: 3A current capacity (versus 1A), 200,000 mechanical cycle rating (versus 100,000), and 100,000 electrical cycle rating (versus 50,000).

Critical Design Considerations:

The YB26CKW01-EB features a larger panel cutout diameter (16.00mm versus 12.30mm). Panel modifications are required if the original 12.30mm cutout cannot be enlarged. Termination style differs; the substitute provides both solder and quick connect options (0.110" / 2.8mm) versus solder lug only on the original part. Circuit board layout and connector compatibility must be evaluated during integration.

Both parts maintain ROHS3 compliance and identical operating temperature specifications. The substitute part's active product status ensures long-term availability and supply chain continuity compared to the obsolete original specification.

Frequently Asked Questions (FAQ)

Q: Can the YB26CKW01-EB directly replace the KB26CKW01-EB in existing designs?

A: Electrical compatibility is confirmed for DPDT On-On switching at 125V AC / 30V DC. Mechanical compatibility requires verification of panel cutout diameter (16.00mm for substitute versus 12.30mm for original) and termination style compatibility (Quick Connect 0.110" / 2.8mm versus Solder Lug).

Q: What are the key differences between these two parts?

A: The YB26CKW01-EB provides higher current rating (3A versus 1A), extended mechanical life (200,000 versus 100,000 cycles), and extended electrical life (100,000 versus 50,000 cycles). Panel cutout diameter and termination options differ. The substitute maintains identical voltage ratings, temperature range, and circuit configuration.

Q: Is the higher current rating of the YB26CKW01-EB a concern for applications designed for 1A?

A: No. Higher current capacity does not create compatibility issues for lower-current applications. The 3A rating of the substitute part provides design margin and is suitable for 1A circuit requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both KB26CKW01-EB and YB26CKW01-EB are ROHS3 compliant, meeting environmental and regulatory requirements.

Q: What is the primary reason to consider the YB26CKW01-EB?

A: The KB26CKW01-EB is classified as obsolete. The YB26CKW01-EB is an active product from the same manufacturer with equivalent electrical specifications, ensuring supply chain availability and long-term design support.
