KB26RKG01 Equivalent & Substitute Parts

Part Overview

The KB26RKG01 is a pushbutton switch manufactured by NKK Switches, configured as a Double Pole Double Throw (DPDT) switch with On-On functionality. This component is rated for 0.4VA at 28V AC/DC and features panel mount, front installation with solder lug termination. The KB26RKG01 is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

The YB26RKG01 qualifies as a substitute for the KB26RKG01 based on the following critical parameters:

Matching Parameters:

• Circuit configuration: DPDT
• Switch function: On-On
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 28V AC/DC
• Mounting type: Panel Mount, Front
• Actuator type: Plunger for Cap
• Operating temperature range: -25°C to 70°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Differing Parameters:

• Termination style: YB26RKG01 uses Solder and Quick Connect (0.110" / 2.8mm) versus KB26RKG01 Solder Lug only
• Panel cutout dimensions: YB26RKG01 requires 16.00mm circular cutout versus KB26RKG01 12.30mm
• Mechanical life: YB26RKG01 rated for 200,000 cycles versus KB26RKG01 100,000 cycles
• Product status: YB26RKG01 is Active versus KB26RKG01 Obsolete
• Packaging: YB26RKG01 supplied in Bulk

Parameter Comparison

Engineering Selection Recommendations

The YB26RKG01 is the active equivalent for the obsolete KB26RKG01. Both components maintain identical electrical specifications (DPDT, On-On, 0.4VA, 28V AC/DC) and thermal operating range (-25°C to 70°C). Both are ROHS3 compliant with MSL rating of 1.

Selection of the YB26RKG01 as a replacement requires evaluation of two design considerations:

1. Panel Cutout Modification: The YB26RKG01 requires a 16.00mm circular cutout compared to the KB26RKG01 12.30mm cutout. Panel redesign or mechanical adaptation may be necessary.

2. Termination Compatibility: The YB26RKG01 provides dual termination options (Solder and Quick Connect 0.110" / 2.8mm) versus the KB26RKG01 Solder Lug only. Existing solder lug connections remain compatible; Quick Connect termination is optional.

The YB26RKG01 offers extended mechanical life (200,000 cycles versus 100,000 cycles) and active product status, supporting long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can YB26RKG01 directly replace KB26RKG01 in existing designs?

A: Electrical and functional compatibility is confirmed. Physical integration requires panel cutout modification from 12.30mm to 16.00mm diameter. Termination compatibility is maintained through solder lug connection capability.

Q: What are the key differences between these parts?

A: The primary differences are panel cutout diameter (12.30mm versus 16.00mm), termination options (solder lug only versus solder plus Quick Connect), and mechanical life rating (100,000 versus 200,000 cycles). Electrical specifications and operating temperature range are identical.

Q: Is the YB26RKG01 suitable for applications requiring 100,000 cycle minimum life?

A: Yes. The YB26RKG01 exceeds this requirement with a 200,000 cycle mechanical life rating.

Q: Are both parts RoHS compliant?

A: Yes. Both KB26RKG01 and YB26RKG01 are ROHS3 compliant with MSL rating 1 (Unlimited).

Q: What packaging is available for the YB26RKG01?

A: The YB26RKG01 is supplied in Bulk packaging, compared to the KB26RKG01 standard packaging designation.
