Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB16KKW01-A is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration must remain SPDT
• Switch function must remain On-On
• Voltage ratings must meet or exceed: 125V AC and 30V DC
• Mounting type must be Panel Mount, Snap-In
• Actuator type must be Square, Button
• Operating temperature range must encompass -25°C to 70°C
• RoHS3 compliance required

Allowable Variations:

• Current rating may exceed 1A (higher current capability is acceptable)
• Mechanical and electrical life cycles may exceed specified minimums
• Termination style may differ if electrical connection is maintained
• Panel cutout diameter may vary within mechanical design constraints
• Product status may transition from obsolete to active

The YB16KKW01-GB qualifies as a substitute based on these criteria, with enhanced electrical and mechanical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The YB16KKW01-GB serves as the active substitute for the obsolete KB16KKW01-A. Selection of this substitute is supported by the following factors:

Compliance and Certification: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment across product lifecycles.

Performance Enhancement: The YB16KKW01-GB provides increased current capacity (3A versus 1A), extended mechanical life (200,000 versus 100,000 cycles), and doubled electrical life (100,000 versus 50,000 cycles). These enhancements provide margin for reliability in applications where the original part is no longer available.

Functional Equivalence: Identical circuit configuration (SPDT), switch function (On-On), voltage ratings (125V AC / 30V DC), and operating temperature range (-25°C to 70°C) ensure direct functional compatibility.

Design Consideration: The panel cutout diameter increases from 12.30mm to 16.00mm, requiring mechanical panel modification. Termination style changes from solder lug to solder with quick connect option, necessitating connection method evaluation during integration.

Active Product Status: The YB16KKW01-GB is classified as active, ensuring ongoing availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the YB16KKW01-GB directly replace the KB16KKW01-A without modification?

A: Functional replacement is possible. However, the larger panel cutout diameter (16.00mm versus 12.30mm) requires mechanical panel modification. The termination style change from solder lug to solder with quick connect option requires connection method evaluation.

Q: What is the significance of the increased current rating in the YB16KKW01-GB?

A: The YB16KKW01-GB is rated for 3A compared to the KB16KKW01-A's 1A rating. This higher current capacity provides design margin and is acceptable for applications originally designed for 1A operation, as the substitute can handle greater electrical loads.

Q: Are the voltage ratings identical between these components?

A: Yes. Both components are rated for 125V AC and 30V DC, ensuring electrical compatibility in equivalent circuit applications.

Q: What does the extended mechanical and electrical life mean for component selection?

A: The YB16KKW01-GB offers 200,000 mechanical cycles and 100,000 electrical cycles compared to 100,000 and 50,000 cycles respectively for the KB16KKW01-A. This extended life provides increased durability and longer service intervals.

Q: Are there compliance differences between the two parts?

A: No. Both components are ROHS3 compliant and REACH unaffected, maintaining identical regulatory status.

Q: What is the primary reason for substitution?

A: The KB16KKW01-A is classified as obsolete. The YB16KKW01-GB is the active equivalent from NKK Switches, ensuring continued component availability and supply chain reliability.
