Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB25CKW01-CB is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must remain DPDT
• Switch function must be On-Mom (momentary operation)
• Voltage ratings must meet or exceed: 125V AC minimum, 30V DC minimum
• Current rating must support the application load

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount, Front
• Actuator type must be Round, Button
• Panel cutout dimensions must accommodate the physical installation

Environmental & Compliance Requirements:

• Operating temperature range must encompass -25°C ~ 70°C
• RoHS3 compliance required
• Moisture sensitivity level MSL 1 acceptable

The YB25CKW01-CB from NKK Switches meets these substitution criteria while offering enhanced performance characteristics in mechanical and electrical life ratings.

Parameter Comparison

Engineering Selection Recommendations

The YB25CKW01-CB is a direct functional substitute for the KB25CKW01-CB. Both components are manufactured by NKK Switches and maintain identical electrical specifications for voltage and circuit configuration. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The YB25CKW01-CB provides enhanced durability with 10x greater mechanical life (1,000,000 cycles versus 100,000 cycles) and doubled electrical life (100,000 cycles versus 50,000 cycles). Both parts maintain ROHS3 compliance and MSL 1 moisture sensitivity rating.

Panel cutout dimension differences exist: the KB25CKW01-CB requires a 12.30mm circular cutout, while the YB25CKW01-CB requires a 16.00mm circular cutout. Physical installation modifications may be necessary depending on existing panel configurations.

Termination style differs between the parts: KB25CKW01-CB uses solder lug termination, while YB25CKW01-CB offers solder and quick connect 0.110" (2.8mm) termination options. Circuit board modifications or connector adaptation may be required.

Frequently Asked Questions (FAQ)

Q: Can the YB25CKW01-CB directly replace the KB25CKW01-CB without modifications?

A: Electrical substitution is direct. However, physical installation requires panel cutout modification from 12.30mm to 16.00mm diameter, and termination style adaptation from solder lug to solder or quick connect terminals.

Q: What is the significance of the higher current rating (3A) on the YB25CKW01-CB?

A: The YB25CKW01-CB is rated for 3A AC/DC current, exceeding the 1A rating of the KB25CKW01-CB. This provides additional design margin and allows the substitute part to support higher current applications while maintaining the same voltage specifications.

Q: Are both parts RoHS3 compliant?

A: Yes, both KB25CKW01-CB and YB25CKW01-CB are ROHS3 compliant with MSL 1 moisture sensitivity rating and REACH unaffected status.

Q: What is the difference in mechanical and electrical life between these parts?

A: The KB25CKW01-CB provides 100,000 mechanical cycles and 50,000 electrical cycles. The YB25CKW01-CB provides 1,000,000 mechanical cycles and 100,000 electrical cycles, representing a 10x and 2x improvement respectively.

Q: Why is the KB25CKW01-CB marked as obsolete?

A: Obsolete status indicates the part is no longer in active production. The YB25CKW01-CB from the same manufacturer represents the current active alternative with enhanced specifications.

Q: Are there packaging differences between these parts?

A: The KB25CKW01-CB is supplied in standard packaging, while the YB25CKW01-CB is supplied in bulk packaging. Inventory availability differs: KB25CKW01-CB has 753 pieces in stock, YB25CKW01-CB has 923 pieces in stock.
