KB25SKW01-BB Equivalent & Substitute Parts

Part Overview

The KB25SKW01-BB is a DPDT pushbutton switch manufactured by NKK Switches, rated for 1A at 125V AC and 30V DC. This component features a standard panel mount configuration with a square white button actuator and solder lug termination. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing maintenance, repair, and design continuity in applications requiring equivalent switching functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB25SKW01-BB is determined by strict compatibility across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration (DPDT)
• Switch function (On-Mom)
• Voltage rating - AC (125V minimum)
• Voltage rating - DC (30V minimum)
• Mounting type (Panel Mount, Front)
• Actuator type (Square, Button)
• Operating temperature range (-25°C to 70°C minimum)

Allowable Variations:

• Current rating may exceed 1A (higher current capacity is acceptable for lower-current applications)
• Mechanical and electrical life may exceed specified values
• Termination style may differ if panel cutout dimensions remain compatible
• Product status may transition from obsolete to active

The YB25SKW01-BB meets all mandatory matching parameters while providing enhanced electrical and mechanical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The YB25SKW01-BB serves as a direct functional substitute for the obsolete KB25SKW01-BB. Both components maintain identical circuit configuration, switch function, voltage ratings, and operating temperature specifications. The YB25SKW01-BB provides enhanced current capacity (3A versus 1A), extended mechanical life (1,000,000 versus 100,000 cycles), and extended electrical life (100,000 versus 50,000 cycles).

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The YB25SKW01-BB is currently in active production status, providing supply continuity and long-term availability advantages over the obsolete KB25SKW01-BB.

Panel cutout dimension differences (12.30mm versus 16.00mm) and termination style variations (Solder Lug versus Solder/Quick Connect) require mechanical integration assessment during component selection. Termination compatibility with existing circuit board or harness designs must be evaluated based on specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the YB25SKW01-BB directly replace the KB25SKW01-BB without circuit modifications?

A: The YB25SKW01-BB maintains identical electrical specifications (DPDT, On-Mom function, 125V AC, 30V DC ratings). Mechanical integration requires assessment of panel cutout dimensions (16.00mm for YB25SKW01-BB versus 12.30mm for KB25SKW01-BB) and termination compatibility (Quick Connect versus Solder Lug).

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

A: The YB25SKW01-BB provides higher current capacity (3A versus 1A), extended mechanical life (1,000,000 versus 100,000 cycles), and extended electrical life (100,000 versus 50,000 cycles). The YB25SKW01-BB is in active production, while the KB25SKW01-BB is obsolete.

Q: Are there any compliance or certification differences?

A: Both parts maintain ROHS3 compliance and REACH unaffected status. No compliance differences exist between the two components.

Q: What considerations apply to panel cutout modifications?

A: The YB25SKW01-BB requires a 16.00mm diameter panel cutout compared to 12.30mm for the KB25SKW01-BB. Panel modifications or adapter solutions may be necessary depending on existing mechanical design constraints.

Q: Is the higher current rating of the YB25SKW01-BB suitable for 1A applications?

A: Yes. The YB25SKW01-BB is rated for 3A (AC/DC), which exceeds the 1A requirement of the original KB25SKW01-BB application. Higher current capacity does not create compatibility issues for lower-current switching applications.
