KB26CKG01-5C-JB Equivalent & Substitute Parts

Part Overview

The KB26CKG01-5C-JB is a pushbutton switch manufactured by NKK Switches, featuring DPDT (Double Pole Double Throw) circuitry with illuminated panel mount design. This component operates at 28V AC/DC with a 0.4VA current rating and includes red LED illumination. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and legacy equipment support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB26CKG01-5C-JB is determined by the following critical parameters:

• Circuit configuration (DPDT required)
• Switch function (On-On operation)
• Electrical ratings (0.4VA at 28V AC/DC)
• Illumination specifications (LED, Red, 1.9 VDC nominal)
• Mounting interface (Panel Mount, Front)
• Actuator design (Round, Button)
• Operating temperature range (-25°C to 50°C)
• Regulatory compliance (ROHS3, REACH status)

The YB26CKG01-5C-JB qualifies as a substitute based on matching all critical electrical and functional parameters. Differences in panel cutout dimensions, termination style, and mechanical life do not preclude substitution when mechanical mounting and electrical interface compatibility are verified for the specific application.

Parameter Comparison

Engineering Selection Recommendations

The YB26CKG01-5C-JB is an active product substitute for the obsolete KB26CKG01-5C-JB. Both components share identical electrical specifications, circuit configuration, and illumination characteristics, ensuring functional compatibility in DPDT pushbutton switch applications rated for 28V AC/DC operation with red LED indication.

Key considerations for selection:

• The YB26CKG01-5C-JB features a larger panel cutout diameter (16.00mm vs. 12.30mm), requiring verification of panel mounting compatibility.
• Termination style differs: the substitute uses Quick Connect terminals (0.110" / 2.8mm) versus solder lugs on the original, necessitating wiring interface assessment.
• The substitute demonstrates extended mechanical life (200,000 cycles vs. 100,000 cycles), providing improved durability in high-cycle applications.
• Both components maintain identical operating temperature range and moisture sensitivity classification.
• The substitute is currently in active production status, ensuring availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the YB26CKG01-5C-JB directly replace the KB26CKG01-5C-JB in existing installations?

A: Electrical and functional compatibility is confirmed. Physical compatibility requires verification of panel cutout dimensions and termination interface. The larger cutout diameter (16.00mm vs. 12.30mm) may necessitate panel modification. Termination style differences (Quick Connect vs. Solder Lug) require wiring interface assessment.

Q: What are the critical parameters that define substitution eligibility?

A: DPDT circuit configuration, On-On switch function, 0.4VA current rating at 28V AC/DC, red LED illumination at 1.9 VDC nominal, round button actuator, panel mount front design, and -25°C to 50°C operating temperature range must all be matched.

Q: Does the difference in mechanical life affect substitution suitability?

A: The YB26CKG01-5C-JB offers superior mechanical life (200,000 cycles vs. 100,000 cycles). This represents an improvement and does not preclude substitution. Application cycle requirements should be evaluated against both specifications.

Q: Are there compliance or regulatory differences between these components?

A: Both components share identical ECCN (EAR99) and moisture sensitivity classification (MSL 1). RoHS3 compliance is specified for the KB26CKG01-5C-JB; compliance status for the YB26CKG01-5C-JB is not provided in available documentation.

Q: What installation modifications may be required?

A: Panel cutout enlargement from 12.30mm to 16.00mm diameter may be necessary. Wiring termination must be adapted from solder lug to Quick Connect 0.110" (2.8mm) interface. Electrical connections and illumination voltage supply remain unchanged.
