KB26RKG01-05-EB Equivalent & Substitute Parts

Part Overview

The KB26RKG01-05-EB is a pushbutton switch manufactured by NKK Switches, configured as a DPDT (Double Pole Double Throw) standard illuminated panel mount switch. This component operates at 28V AC/DC with a current rating of 0.4VA and features yellow incandescent illumination at 5VAC. The switch is rated for 100,000 mechanical and electrical cycles with an operating temperature range of -25°C to 50°C.

This part is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for applications requiring DPDT illuminated pushbutton switches with these electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

The YB26RKG01-5D05-JD qualifies as a substitute for the KB26RKG01-05-EB based on the following critical parameters:

Electrical Compatibility:

• Both parts maintain DPDT circuit configuration with On-On switch function
• Both rated for 0.4VA (AC/DC) current
• Both support 28V AC and 28V DC operation
• Both feature illumination at 5V nominal (incandescent vs. LED)

Mechanical Compatibility:

• Both use panel mount, front installation
• Both feature rectangular button actuators without marking
• Both operate across -25°C to 50°C temperature range
• Both are ROHS3 compliant

Substitution Constraints:

• Panel cutout dimensions differ: KB26RKG01-05-EB requires 12.30mm circular cutout; YB26RKG01-5D05-JD requires 16.00mm circular cutout
• Termination style differs: KB26RKG01-05-EB uses solder lug; YB26RKG01-5D05-JD uses solder with quick connect 0.110" (2.8mm)
• Illumination type differs: KB26RKG01-05-EB uses incandescent yellow; YB26RKG01-5D05-JD uses LED amber
• Mechanical life rating differs: KB26RKG01-05-EB rated 100,000 cycles; YB26RKG01-5D05-JD rated 200,000 cycles

Parameter Comparison

Engineering Selection Recommendations

The YB26RKG01-5D05-JD is an active product substitute for the obsolete KB26RKG01-05-EB. Both components maintain identical electrical specifications (DPDT, 0.4VA, 28V AC/DC) and core mechanical compatibility (panel mount, rectangular button, -25°C to 50°C operation).

Selection of the YB26RKG01-5D05-JD requires evaluation of three implementation factors:

Panel Integration: The substitute requires a 16.00mm circular panel cutout versus the original 12.30mm. Panel modification or adapter mounting may be necessary.

Termination Compatibility: The substitute uses quick connect 0.110" (2.8mm) terminals with solder capability, whereas the original uses solder lugs. Wiring harness reconfiguration is required.

Illumination Characteristics: The substitute employs LED amber illumination at 5VDC with voltage reduction lighting features, replacing the original incandescent yellow illumination at 5VAC. This affects power supply requirements and visual indication appearance.

Both components are ROHS3 compliant with MSL rating 1 (unlimited moisture sensitivity). The substitute offers extended mechanical life (200,000 cycles vs. 100,000 cycles).

Frequently Asked Questions (FAQ)

Q: Can the YB26RKG01-5D05-JD directly replace the KB26RKG01-05-EB without modifications?

A: Electrical substitution is valid. However, physical installation requires panel cutout enlargement from 12.30mm to 16.00mm diameter. Termination wiring must be adapted from solder lug to quick connect 0.110" (2.8mm) terminals. Illumination power supply must transition from 5VAC to 5VDC.

Q: What are the key electrical parameters that define substitution eligibility?

A: DPDT circuit configuration, On-On switch function, 0.4VA current rating, and 28V AC/DC voltage rating are the primary electrical criteria. Both parts meet these specifications identically.

Q: Does the illumination type change affect system functionality?

A: The substitute uses LED amber illumination instead of incandescent yellow. Both operate at 5V nominal with identical visual indication purpose. The LED variant includes voltage reduction lighting features. Power supply architecture must support 5VDC instead of 5VAC.

Q: Are there compliance differences between the two parts?

A: Both components are ROHS3 compliant with MSL rating 1 (unlimited). The original is REACH unaffected; the substitute is REACH affected. Both carry ECCN EAR99 and HTSUS 8536.50.9033 classifications.

Q: What is the mechanical life difference significance?

A: The substitute is rated for 200,000 mechanical cycles versus the original 100,000 cycles. This represents extended component longevity for applications with frequent switch actuation.
