KB16CKW01 Equivalent & Substitute Parts

Part Overview

The KB16CKW01 is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry with On-On switching function. This component is rated for 1A at 125V AC and 30V DC, designed for standard panel mount front installation with solder lug termination. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing maintenance, repair, and new design implementations where equivalent functionality is required.

Substitute Part Grouping Explanation

Substitution eligibility for the KB16CKW01 is determined by the following critical parameters:

Core Electrical Compatibility Requirements:

  • Circuit configuration must be SPDT
  • Switch function must be On-On
  • 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, Front
  • Actuator type must be Plunger for Cap
  • Operating temperature range must encompass or match: -25°C ~ 70°C

Termination Consideration:

  • Primary termination is Solder Lug; however, alternative termination styles (such as Quick Connect) may be acceptable depending on circuit board design and assembly process compatibility

The YB16CKW01 meets the core electrical requirements with enhanced current rating (3A), maintains SPDT On-On configuration, and operates within the specified temperature range. However, mechanical differences exist in panel cutout dimensions and termination style options.

Engineering Selection Recommendations

The YB16CKW01 is an active product from NKK Switches and represents a viable substitute for the obsolete KB16CKW01 based on electrical and functional equivalence. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

Electrical Compatibility: The YB16CKW01 exceeds the electrical requirements of the KB16CKW01, providing 3A current capacity versus the original 1A specification, while maintaining identical voltage ratings (125V AC / 30V DC). This enhanced current rating provides operational margin in applications where the original 1A specification is adequate.

Mechanical Considerations: The panel cutout dimension differs between the two parts (12.30mm versus 16.00mm). Panel redesign or mechanical adaptation may be required if the original mounting hole cannot be enlarged. The YB16CKW01 offers dual termination options (Solder and Quick Connect), providing flexibility for different assembly processes.

Lifecycle Status: The transition from an obsolete part (KB16CKW01) to an active product (YB16CKW01) ensures long-term component availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the YB16CKW01 directly replace the KB16CKW01 in existing designs?

A: Electrical substitution is valid. However, the larger panel cutout dimension (16.00mm versus 12.30mm) requires mechanical verification. If the original panel hole cannot be enlarged, mechanical adaptation is necessary.

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

A: The YB16CKW01 provides higher current rating (3A versus 1A), extended mechanical and electrical life cycles, and dual termination options. Both maintain identical voltage ratings, circuit configuration, and operating temperature range.

Q: Is the higher current rating of the YB16CKW01 a concern for applications designed for 1A?

A: No. The YB16CKW01 is rated for 3A maximum; applications requiring 1A operation remain within safe operating parameters.

Q: Does the termination style difference affect electrical performance?

A: Termination style affects assembly process compatibility, not electrical performance. The YB16CKW01 offers both Solder Lug and Quick Connect options, providing flexibility for different manufacturing environments.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the KB16CKW01 and YB16CKW01 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: What is the mechanical life difference, and does it matter?

A: The YB16CKW01 offers 200,000 cycles versus the KB16CKW01's 100,000 cycles. This extended life provides greater durability in high-cycle applications, though both are suitable for standard panel mount switch applications.
