KB26NKG01 Equivalent & Substitute Parts

Part Overview

The KB26NKG01 is a pushbutton switch with DPDT (Double Pole Double Throw) configuration manufactured by NKK Switches. This component is rated for 0.4VA at 28V AC/DC and features panel mount, snap-in installation with solder lug termination. The part is currently obsolete, making identification of compatible substitute components essential for system maintenance, repair, and redesign applications. The YB26NKG01 represents the active equivalent in NKK Switches' current product portfolio.

Substitute Part Grouping Explanation

The YB26NKG01 qualifies as a direct substitute for the KB26NKG01 based on the following critical parameters:

• Electrical Equivalence: Both parts maintain identical DPDT circuit configuration, On-On switch function, 0.4VA current rating, and 28V AC/DC voltage ratings
• Mechanical Compatibility: Both feature panel mount, snap-in installation with plunger actuator type and identical operating temperature range (-25°C to 70°C)
• Compliance Alignment: Both are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH unaffected status

Substitution is valid where the following differences are acceptable to the application:

• Panel cutout diameter increases from 12.30mm to 16.00mm
• Termination style changes from solder lug to solder with quick connect 0.110" (2.8mm)
• Mechanical life rating increases from 100,000 to 200,000 cycles
• Product status transitions from obsolete to active

Engineering Selection Recommendations

The YB26NKG01 is the recommended substitute for the obsolete KB26NKG01. Both components maintain full electrical and functional equivalence with identical voltage, current, and circuit specifications. The YB26NKG01 offers the advantage of active product status with extended mechanical life (200,000 cycles versus 100,000 cycles), ensuring continued availability and improved durability.

Both parts satisfy ROHS3 compliance and REACH requirements, making them suitable for applications with environmental and regulatory constraints. The primary consideration for substitution involves panel cutout diameter accommodation (16.00mm versus 12.30mm) and termination style compatibility (quick connect versus solder lug). These differences require mechanical and electrical interface verification during integration.

Frequently Asked Questions (FAQ)

Q: Can the YB26NKG01 directly replace the KB26NKG01 in existing designs?

A: Electrical and functional replacement is direct. Mechanical integration requires verification of panel cutout diameter (16.00mm for YB26NKG01 versus 12.30mm for KB26NKG01) and termination compatibility (quick connect 0.110" versus solder lug).

Q: Are the voltage and current ratings identical between these parts?

A: Yes. Both the KB26NKG01 and YB26NKG01 are rated for 0.4VA at 28V AC/DC with identical DPDT On-On circuit configuration.

Q: What is the significance of the increased mechanical life rating in the YB26NKG01?

A: The YB26NKG01 provides 200,000 mechanical cycles compared to 100,000 cycles in the KB26NKG01. This extended rating indicates improved durability and longer operational life expectancy in high-cycle applications.

Q: Are both parts compliant with current environmental standards?

A: Yes. Both the KB26NKG01 and YB26NKG01 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH unaffected status.

Q: What termination options are available?

A: The KB26NKG01 uses solder lug termination, while the YB26NKG01 provides solder with quick connect 0.110" (2.8mm) termination. Selection depends on circuit board design and assembly requirements.
