Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB26MKW01-CC is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration: DPDT
• Switch function: On-On
• Voltage rating: Minimum 125V AC / 30V DC
• Mounting type: Panel Mount, Snap-In
• Actuator type: Round, Button
• Operating temperature range: -25°C to 70°C or wider
• RoHS compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Current rating: May exceed 1A (higher current ratings are compatible for lower-current applications)
• Mechanical and electrical life: May exceed specified cycles
• Panel cutout diameter: Larger diameters require panel modification
• Termination style: May differ if circuit board layout permits

The YB26MKW01-CB meets all mandatory compatibility parameters while exceeding performance specifications in current rating (3A), mechanical life (200,000 cycles), and electrical life (100,000 cycles).

Parameter Comparison

Engineering Selection Recommendations

The YB26MKW01-CB is a direct functional substitute for the KB26MKW01-CC based on electrical and mechanical compatibility. Both components are manufactured by NKK Switches, maintain identical circuit configuration (DPDT), switch function (On-On), and voltage ratings (125V AC / 30V DC). Both are ROHS3 compliant and operate within the same temperature range.

The YB26MKW01-CB offers enhanced performance characteristics with a higher current rating (3A versus 1A) and extended mechanical and electrical life cycles, making it suitable for applications requiring the KB26MKW01-CC specifications. The substitute part is currently in active production status, ensuring long-term availability.

Physical integration considerations include panel cutout diameter differences (16.00mm for YB26MKW01-CB versus 12.30mm for KB26MKW01-CC) and termination style variation (Quick Connect option available on substitute). These differences require panel modification and circuit board layout assessment during implementation.

Frequently Asked Questions (FAQ)

Q: Can the YB26MKW01-CB directly replace the KB26MKW01-CC without circuit modification?

A: Electrical substitution is valid. The higher current rating (3A) is compatible with 1A applications. However, panel cutout diameter differs (16.00mm versus 12.30mm), requiring panel modification. Termination style differences (Solder Lug versus Solder/Quick Connect) require circuit board layout assessment.

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

A: Primary differences are current rating (1A to
