Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Compatibility Parameters:

• Circuit configuration: DPDT
• Switch function: On-On
• 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 acceptable for lower-current applications)
• Electrical life: May exceed 50,000 cycles
• Mechanical life: May exceed 100,000 cycles
• Termination style: May differ if panel cutout dimensions remain compatible
• Panel cutout diameter: Must accommodate the original 12.30mm specification

The YB26CKW01-GB meets the mandatory compatibility criteria while providing enhanced electrical and mechanical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The YB26CKW01-GB is an active product from NKK Switches and serves as the functional equivalent for KB26CKW01-GG applications. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Selection Considerations:

The YB26CKW01-GB provides superior performance specifications with 3A current capacity versus the original 1A rating, doubled mechanical life (200,000 cycles), and doubled electrical life (100,000 cycles). These enhancements ensure extended service life in equivalent or higher-demand applications.

Physical Integration Factors:

The panel cutout diameter increases from 12.30mm to 16.00mm. Panel modifications may be required for direct mechanical replacement. The termination style changes from solder lug to solder with quick connect options, requiring evaluation of existing circuit board or wiring connections.

Compliance Status:

Both components maintain identical voltage ratings (125V AC, 30V DC) and operating temperature specifications (-25°C to 70°C), ensuring functional compatibility in the original application environment.

Frequently Asked Questions (FAQ)

Q: Can YB26CKW01-GB directly replace KB26CKW01-GG without modification?

A: Functional replacement is possible. However, the larger panel cutout diameter (16.00mm versus 12.30mm) requires panel modification. Termination style differences (solder lug versus solder/quick connect) require circuit connection evaluation.

Q: What is the primary reason for substitution?

A: KB26CKW01-GG is obsolete. YB26CKW01-GB is an active product offering identical circuit configuration, voltage ratings, and operating temperature range with enhanced current and life cycle ratings.

Q: Are both components RoHS compliant?

A: Yes. Both KB26CKW01-GG and YB26CKW01-GB are ROHS3 compliant and REACH unaffected.

Q: Does the higher current rating of YB26CKW01-GB affect compatibility?

A: No. A 3A-rated component is suitable for applications requiring 1A or less. The higher rating provides design margin and extended component life.

Q: What are the mechanical life differences?

A: KB26CKW01-GG is rated for 100,000 mechanical cycles. YB26CKW01-GB is rated for 200,000 mechanical cycles, doubling the expected service life.

Q: Are packaging differences significant?

A: KB26CKW01-GG uses standard packaging. YB26CKW01-GB uses bulk packaging. This affects procurement and inventory management but not component functionality.
