KB26SKW01-6G-JB Equivalent & Substitute Parts

Part Overview

The KB26SKW01-6G-JB is a pushbutton switch with DPDT (Double Pole Double Throw) circuit configuration, rated for 1A at 125V AC and 30V DC. This illuminated panel mount switch features a square button actuator with blue LED illumination at 3.6VDC nominal voltage and solder lug termination. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

The YB26SKW01-6G-JB qualifies as a functional substitute based on the following alignment of critical parameters:

Matching Parameters:

• Circuit configuration: DPDT (identical switching topology)
• Voltage rating - AC: 125V (identical)
• Voltage rating - DC: 30V (identical)
• Mounting type: Panel Mount, Front (identical mechanical interface)
• Illumination type and color: LED, Blue (identical)
• Illumination voltage: 3.6VDC (identical)
• Actuator type: Square, Button (identical form factor)
• Operating temperature range: -25°C to 50°C (identical)
• RoHS3 compliance: Yes (identical regulatory status)

Differing Parameters:

• Current rating: 3A vs. 1A (substitute has higher capacity)
• Mechanical life: 200,000 cycles vs. 100,000 cycles (substitute has extended durability)
• Electrical life: 100,000 cycles vs. 50,000 cycles (substitute has extended durability)
• Panel cutout diameter: 16.00mm vs. 12.30mm (requires panel modification)
• Termination style: Solder, Quick Connect - 0.110" vs. Solder Lug (requires wiring adaptation)
• Product status: Active vs. Obsolete (substitute is currently manufactured)

Parameter Comparison

Engineering Selection Recommendations

The YB26SKW01-6G-JB is electrically compatible with the KB26SKW01-6G-JB for applications requiring DPDT switching at 125V AC / 30V DC with blue LED illumination. The substitute part offers superior electrical and mechanical durability with extended cycle life ratings.

Implementation of this substitute requires consideration of mechanical integration factors. The larger panel cutout diameter (16.00mm vs. 12.30mm) necessitates panel modification or use of an adapter bezel. The termination style change from solder lug to solder with quick connect 0.110" requires wiring harness adaptation.

The substitute's higher current rating (3A vs. 1A) provides operational margin for the specified circuit and does not introduce compatibility issues in applications designed for the original 1A rating. The active product status of YB26SKW01-6G-JB ensures ongoing availability and supply chain continuity compared to the obsolete KB26SKW01-6G-JB.

Both parts maintain identical regulatory compliance (ROHS3, REACH Unaffected, EAR99 ECCN classification) and operational temperature specifications.

Frequently Asked Questions (FAQ)

Q: Can YB26SKW01-6G-JB directly replace KB26SKW01-6G-JB without modifications?

A: Electrical substitution is direct. Mechanical integration requires panel cutout enlargement from 12.30mm to 16.00mm diameter and termination harness adaptation from solder lug to quick connect 0.110" configuration.

Q: Are the voltage and current ratings compatible?

A: Yes. Both parts operate at 125V AC and 30V DC. The substitute's 3A current rating exceeds the original 1A specification, providing operational margin without introducing compatibility issues.

Q: What is the impact of the different termination styles?

A: The KB26SKW01-6G-JB uses solder lug termination for direct PCB or wire soldering. The YB26SKW01-6G-JB provides solder with quick connect 0.110" (2.8mm) termination, requiring harness connector adaptation or direct soldering to the quick connect terminals.

Q: Are the illumination specifications identical?

A: Yes. Both parts feature blue LED illumination at 3.6VDC nominal voltage with identical actuator color (clear with white filter/diffuser).

Q: What are the durability differences?

A: The substitute offers extended mechanical life (200,000 vs. 100,000 cycles) and electrical life (100,000 vs. 50,000 cycles), providing longer operational service intervals.

Q: Is the substitute currently available?

A: Yes. YB26SKW01-6G-JB is classified as active product status with 921 pieces in stock, compared to the obsolete KB26SKW01-6G-JB status.
