KB16NKW01 Equivalent & Substitute Parts

Part Overview

The KB16NKW01 is a pushbutton switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 1A at 125V AC and 30V DC. This component features a standard panel mount, snap-in design with a plunger actuator and solder lug termination. The KB16NKW01 is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where this series is no longer available.

Key Parameters

Substitute Part Grouping Explanation

The YB16NKW01 qualifies as a functional substitute for the KB16NKW01 based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Circuit configuration: SPDT (Single Pole Double Throw)
• Switch function: On-On
• Voltage rating - AC: 125V
• Voltage rating - DC: 30V
• Mounting type: Panel Mount, Snap-In
• Actuator type: Plunger for Cap
• Operating temperature range: -25°C to 70°C
• RoHS compliance: ROHS3 Compliant
• REACH status: REACH Unaffected

Substitution Basis: The YB16NKW01 maintains electrical compatibility through identical AC/DC voltage ratings and SPDT circuit topology. Both components operate within the same temperature envelope and meet equivalent environmental compliance standards. The YB series represents an active product line from NKK Switches, providing design continuity for applications previously using the obsolete KB series.

Engineering Selection Recommendations

The YB16NKW01 is the designated substitute for the obsolete KB16NKW01. Selection of the YB16NKW01 is supported by:

• Active product status ensuring long-term availability and supply chain continuity
• Identical voltage ratings (125V AC / 30V DC) and SPDT circuit topology
• Equivalent operating temperature range (-25°C to 70°C)
• ROHS3 compliance and REACH unaffected status matching the original component
• Enhanced electrical and mechanical life ratings (200,000 mechanical cycles and 100,000 electrical cycles versus 100,000 and 50,000 respectively)
• Higher current rating (3A versus 1A) providing design margin for existing applications

Physical integration requires panel cutout modification from 12.30mm to 16.00mm diameter. Termination style differs (solder lug versus solder with quick connect option), necessitating circuit board layout adjustment.

Frequently Asked Questions (FAQ)

Q: Can the YB16NKW01 directly replace the KB16NKW01 without circuit modifications?

A: Electrical substitution is valid. However, physical integration requires panel cutout enlargement from 12.30mm to 16.00mm diameter and termination style adaptation from solder lug to solder/quick connect configuration.

Q: What is the current rating difference between these parts?

A: The KB16NKW01 is rated for 1A (AC/DC), while the YB16NKW01 is rated for 3A (AC/DC). The higher rating of the YB16NKW01 provides additional design margin and does not create incompatibility with circuits designed for 1A operation.

Q: Are both components RoHS compliant?

A: Yes. Both the KB16NKW01 and YB16NKW01 are ROHS3 compliant and REACH unaffected, meeting equivalent environmental standards.

Q: What is the mechanical life difference?

A: The KB16NKW01 has a mechanical life rating of 100,000 cycles, while the YB16NKW01 is rated for 200,000 cycles. The YB16NKW01 offers extended operational durability.

Q: Why is the panel cutout size different?

A: The YB series uses a larger 16.00mm diameter cutout compared to the KB series 12.30mm diameter. Panel modifications are required for physical installation.

Q: Is the YB16NKW01 available in the same packaging as the KB16NKW01?

A: The KB16NKW01 is supplied in Tray packaging, while the YB16NKW01 is supplied in Bulk packaging. Packaging format should be confirmed with the supplier based on procurement requirements.
