KB15NKW01 Equivalent & Substitute Parts

Part Overview

The KB15NKW01 is a pushbutton switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 1A at 125V AC and 30V DC. It features a standard panel mount, snap-in design with a plunger actuator and solder lug termination. The product is currently obsolete, making identification of suitable substitute components essential for ongoing maintenance, repair, and redesign applications where this switch was originally specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB15NKW01 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must remain SPDT
• Switch function must be On-Mom (momentary operation)
• Voltage ratings must meet or exceed: 125V AC and 30V DC
• Current rating must meet or exceed: 1A AC/DC

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount, Snap-In
• Actuator type must be Plunger for Cap
• Panel cutout diameter must accommodate the original 12.30mm specification or be compatible with panel modifications

Environmental & Compliance Requirements:

• Operating temperature range must encompass -25°C to 70°C
• RoHS3 compliance required
• REACH unaffected status required

The YB15NKW01 meets all electrical, mechanical, and compliance criteria for substitution. While it offers enhanced performance characteristics (higher current rating, improved mechanical life), it remains functionally compatible with the original KB15NKW01 specification.

Parameter Comparison

Engineering Selection Recommendations

The YB15NKW01 is a valid substitute for the KB15NKW01 based on the following factors:

Compliance & Availability: The KB15NKW01 is obsolete, making the YB15NKW01 the appropriate active alternative from NKK Switches. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

Electrical Equivalence: The YB15NKW01 maintains identical voltage ratings (125V AC, 30V DC) and circuit configuration (SPDT, On-Mom). The increased current rating (3A versus 1A) provides margin for the original application without introducing incompatibility.

Mechanical Considerations: Panel cutout diameter increases from 12.30mm to 16.00mm. Applications using the KB15NKW01 require panel modification to accommodate the larger cutout. Termination style differs (solder lug to solder/quick connect), requiring wiring harness adaptation.

Performance Enhancement: The YB15NKW01 offers extended mechanical life (1,000,000 cycles versus 100,000 cycles) and electrical life (100,000 cycles versus 50,000 cycles), providing improved reliability for the substituted application.

Frequently Asked Questions (FAQ)

Q: Can the YB15NKW01 directly replace the KB15NKW01 without modifications?

A: Electrical and functional replacement is direct. Mechanical installation requires panel cutout modification due to diameter increase from 12.30mm to 16.00mm. Termination style differs, requiring wiring harness reconfiguration.

Q: What are the key differences between these parts?

A: Current rating increases from 1A to 3A. Mechanical and electrical life ratings improve significantly. Panel cutout diameter increases from 12.30mm to 16.00mm. Termination changes from solder lug to solder/quick connect 0.110" (2.8mm).

Q: Are both parts RoHS compliant?

A: Yes. Both KB15NKW01 and YB15NKW01 are ROHS3 compliant and REACH unaffected.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -25°C to 70°C.

Q: Why is the KB15NKW01 obsolete?

A: Product status reflects NKK Switches' current manufacturing and support status. The YB15NKW01 represents the active equivalent in the product line.

Q: Does the higher current rating of the YB15NKW01 affect compatibility?

A: No. Higher current rating provides additional capacity without affecting compatibility with applications designed for 1A operation.
