Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB16MKW01-CC is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must remain SPDT
• Switch function must remain On-On
• Voltage ratings must meet or exceed: 125V AC and 30V DC
• Current rating must meet or exceed: 1A

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount, Snap-In
• Actuator type must be Round, Button
• Operating temperature range must encompass -25°C to 70°C
• Panel cutout dimensions must be compatible with installation

Regulatory & Environmental Requirements:

• RoHS3 compliance required
• Moisture Sensitivity Level (MSL) of 1 or equivalent

The substitute part YB16MKW01-CB meets these criteria with enhanced electrical and mechanical performance characteristics while maintaining functional equivalence for SPDT On-On switching applications.

Parameter Comparison

Engineering Selection Recommendations

The YB16MKW01-CB serves as a direct functional substitute for the obsolete KB16MKW01-CC. Both components maintain identical SPDT On-On switching configuration and voltage specifications (125V AC / 30V DC). The substitute part is manufactured by the same supplier (NKK Switches) and carries active product status with full ROHS3 compliance.

Key considerations for selection:

Electrical Performance: The YB16MKW01-CB provides higher current capacity (3A versus 1A), making it suitable for applications requiring the original 1A rating and those with potential future current demands up to 3A.

Mechanical Durability: Enhanced mechanical life (200,000 cycles versus 100,000 cycles) and electrical life (100,000 cycles versus 50,000 cycles) provide extended operational reliability.

Installation Compatibility: The panel cutout diameter increases from 12.30mm to 16.00mm. This dimensional change requires panel modification or redesign of mounting hardware.

Termination Options: The substitute offers dual termination capability (Solder and Quick Connect 0.110" / 2.8mm) compared to the original solder lug only configuration, providing installation flexibility.

Regulatory Status: Both components maintain identical compliance certifications (ROHS3, MSL 1), ensuring regulatory equivalence for applications subject to environmental and hazardous substance restrictions.

Frequently Asked Questions (FAQ)

Q: Can YB16MKW01-CB directly replace KB16MKW01-CC without circuit modifications?

A: Electrical substitution is direct. Both components feature identical SPDT On-On switching function and voltage ratings (125V AC / 30V DC). The higher current rating (3A) of the substitute is backward compatible with 1A applications. However, panel cutout diameter changes from 12.30mm to 16.00mm, requiring mechanical modification to the mounting panel.

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

A: The primary electrical difference is current capacity: KB16MKW01-CC is rated 1A while YB16MKW01-CB is rated 3A. Both maintain identical voltage specifications and SPDT On-On switching configuration. The substitute provides enhanced electrical life (100,000 cycles versus 50,000 cycles).

Q: Are there termination compatibility issues?

A: The original part uses solder lug termination exclusively. The substitute offers both solder and quick connect (0.110" / 2.8mm) termination options. Solder lug connections remain compatible; however, circuit board or harness modifications may be required to utilize the quick connect option.

Q: Does the panel cutout size difference affect substitution feasibility?

A: Yes. The panel cutout diameter increases from 12.30mm to 16.00mm. Existing panel mounting holes designed for the KB16MKW01-CC will not accommodate the YB16MKW01-CB without enlargement or panel redesign.

Q: Are both parts RoHS compliant?

A: Yes. Both KB16MKW01-CC and YB16MKW01-CB are ROHS3 compliant with MSL rating of 1 (Unlimited), ensuring equivalent regulatory status for applications subject to hazardous substance restrictions.

Q: What is the mechanical life advantage of the substitute?

A: The YB16MKW01-CB provides 200,000 mechanical cycles compared to 100,000 cycles for the KB16MKW01-CC, representing a 2x improvement in mechanical durability and extended service life in high-cycle applications.
