KB26KKW01-CC Equivalent & Substitute Parts

Part Overview

The KB26KKW01-CC is a pushbutton switch manufactured by NKK Switches, configured as a DPDT (Double Pole Double Throw) standard panel mount, snap-in component with a 1A current rating at 125V AC. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB26KKW01-CC is determined by the following critical parameters:

• Circuit configuration must remain DPDT
• Switch function must remain On-On
• Voltage ratings must meet or exceed: 125V AC and 30V DC
• Current rating must meet or exceed: 1A AC/DC
• Mounting type must be Panel Mount, Snap-In compatible
• Actuator type must be Square, Button
• Operating temperature range must encompass or match: -25°C ~ 70°C
• Termination style compatibility with circuit board design
• Panel cutout dimensions must be mechanically compatible or adaptable

The LB26SGW01-C meets the core electrical and functional requirements as a DPDT On-On switch with superior current handling (3A), matching voltage ratings (125V AC / 30V DC), and extended mechanical life (200,000 cycles vs. 100,000 cycles). However, mechanical compatibility requires evaluation due to differences in panel cutout geometry and termination style.

Parameter Comparison

Engineering Selection Recommendations

The LB26SGW01-C is an active product with current manufacturing support from NKK Switches, providing supply chain continuity for applications currently using the obsolete KB26KKW01-CC. Both parts maintain identical compliance certifications (ROHS3, REACH Unaffected, EAR99 ECCN classification).

Electrical compatibility is established: the LB26SGW01-C exceeds the current rating requirement (3A vs. 1A) while maintaining identical voltage specifications (125V AC / 30V DC). Temperature operating ranges are identical (-25°C ~ 70°C).

Mechanical integration requires panel modification assessment. The KB26KKW01-CC uses a circular 12.30mm diameter cutout, while the LB26SGW01-C requires a square 16.20mm x 16.20mm cutout. Termination differs: the original uses solder lugs; the substitute offers solder and quick connect 0.110" (2.8mm) options. These differences necessitate evaluation of panel geometry and circuit board connection methods before implementation.

Frequently Asked Questions (FAQ)

Q: Can the LB26SGW01-C directly replace the KB26KKW01-CC without panel modification?

A: Electrical substitution is valid. Mechanical compatibility depends on panel cutout geometry. The circular 12.30mm cutout of the KB26KKW01-CC differs from the square 16.20mm x 16.20mm requirement of the LB26SGW01-C. Panel drilling or adapter consideration is necessary.

Q: Are the voltage and current ratings compatible?

A: Yes. The LB26SGW01-C maintains 125V AC and 30V DC ratings identical to the KB26KKW01-CC. The increased current rating (3A vs. 1A) provides additional margin for the same electrical specifications.

Q: What is the difference in termination style between these parts?

A: The KB26KKW01-CC uses solder lugs for direct PCB soldering. The LB26SGW01-C offers both solder and quick connect 0.110" (2.8mm) termination options, providing flexibility in circuit board connection methods.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the KB26KKW01-CC and LB26SGW01-C are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes (8536.50.9033).

Q: What is the mechanical life difference?

A: The LB26SGW01-C provides 200,000 mechanical cycles compared to 100,000 cycles for the KB26KKW01-CC, representing a 2x improvement in mechanical durability. Electrical life also doubles from 50,000 to 100,000 cycles.

Q: Is the LB26SGW01-C currently available?

A: Yes. The LB26SGW01-C is classified as an active product with current manufacturing status, unlike the obsolete KB26KKW01-CC. Supply availability is established through NKK Switches distribution channels.
