Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB16KKW01B-A is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration: SPDT
• Switch function: On-On
• Voltage rating: 125V AC minimum, 30V DC minimum
• Mounting type: Panel Mount, Snap-In
• Operating temperature range: -25°C to 70°C minimum
• RoHS compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Current rating: May exceed 1A (higher current rating is acceptable for lower-current applications)
• Mechanical and electrical life: May exceed specified values
• Panel cutout diameter: Larger diameter acceptable if mechanical integration permits
• Termination style: Variation acceptable if electrical connection requirements are met
• Actuator color: Variation acceptable if functional requirements are met

The YB16KKW01-GB meets all mandatory compatibility parameters while exceeding several performance specifications, making it a valid substitute for the obsolete KB16KKW01B-A.

Engineering Selection Recommendations

The YB16KKW01-GB is suitable as a substitute for KB16KKW01B-A applications based on the following engineering criteria:

Compliance and Regulatory Status: Both components maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with current manufacturing and environmental standards. The YB16KKW01-GB carries active product status, providing long-term availability and supply chain stability compared to the obsolete KB16KKW01B-A.

Electrical Performance: The substitute part exceeds the electrical specifications of the original component. The 3A current rating accommodates applications requiring the original 1A specification, while maintaining identical voltage ratings (125V AC, 30V DC) and circuit configuration (SPDT On-On).

Mechanical Durability: The YB16KKW01-GB provides enhanced mechanical and electrical life ratings (200,000 and 100,000 cycles respectively) compared to the original part (100,000 and 50,000 cycles), supporting extended operational requirements.

Physical Integration: Panel cutout diameter increases from 12.30mm to 16.00mm. This dimensional change requires mechanical integration verification to ensure compatibility with existing panel mounting hardware and enclosure designs.

Termination Consideration: The substitute part offers dual termination options (Solder and Quick Connect 0.110"), providing flexibility beyond the original solder lug configuration. Application requirements determine which termination style is appropriate.

Frequently Asked Questions (FAQ)

Q: Can YB16KKW01-GB directly replace KB16KKW01B-A in existing designs?

A: Electrical and functional compatibility is confirmed. Mechanical integration requires verification due to panel cutout diameter increase from 12.30mm to 16.00mm. Termination style compatibility must be assessed based on circuit board design.

Q: What are the key differences between these components?

A: Current rating increases from 1A to 3A. Mechanical and electrical life ratings double. Panel cutout diameter increases by 3.70mm. Termination options expand from solder lug only to solder and quick connect configurations. Product status changes from obsolete to active.

Q: Are both components RoHS compliant?

A: Yes. Both KB16KKW01B-A and YB16KKW01-GB maintain ROHS3 compliance and MSL Level 1 rating.

Q: Does the higher current rating of YB16KKW01-GB affect circuit operation?

A: No. Higher current rating indicates increased component capacity. Applications designed for 1A operation function within the 3A rating of the substitute part without performance degradation.

Q: What packaging considerations apply to YB16KKW01-GB?

A: The substitute part is supplied in bulk packaging. Inventory availability is confirmed at 941 pieces in new original condition.

Q: Are the operating temperature ranges identical?

A: Yes. Both components operate across -25°C to 70°C, ensuring thermal compatibility in equivalent applications.
