Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB26SKW01-05-EB is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration (DPDT)
• Switch function (On-On)
• Voltage ratings (125V AC minimum, 30V DC minimum)
• Mounting type (Panel Mount, Front)
• Illumination capability (required)
• Operating temperature range (-25°C to 50°C minimum)
• Panel cutout dimensions (mechanical fit requirement)

Allowable Variations:

• Current rating may exceed 1A (higher ratings are backward compatible)
• Illumination type may differ (LED vs. Incandescent)
• Illumination voltage may differ if within system tolerance
• Mechanical and electrical life may exceed specified minimums
• Termination style may vary based on circuit board design

The YB26SKW01-5D05-JD meets the mandatory compatibility parameters while offering enhanced performance characteristics in current rating, mechanical life, and electrical life.

Parameter Comparison

Engineering Selection Recommendations

The YB26SKW01-5D05-JD is a functionally equivalent substitute for the obsolete KB26SKW01-05-EB. The substitute part maintains identical voltage ratings, circuit configuration, and mounting specifications while providing enhanced performance in current capacity and operational life metrics.

Key Considerations:

The substitute part features a larger panel cutout diameter (16.00mm vs. 12.30mm), requiring mechanical panel modification for direct replacement in existing assemblies. The illumination technology transition from incandescent to LED and the shift from 5VAC to 5VDC illumination voltage necessitate verification of the illumination circuit design in the target application.

The YB26SKW01-5D05-JD is currently in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete KB26SKW01-05-EB. The substitute part's higher current rating (3A vs. 1A) and extended mechanical life (200,000 vs. 100,000 cycles) provide design margin for applications requiring sustained reliability.

Frequently Asked Questions (FAQ)

Q: Can the YB26SKW01-5D05-JD directly replace the KB26SKW01-05-EB without circuit modifications?

A: The electrical circuit compatibility is confirmed for DPDT On-On switching at the specified voltage and current levels. However, the illumination voltage differs (5VDC vs. 5VAC), requiring verification that the illumination circuit can supply DC voltage. The panel cutout diameter increase (16.00mm vs. 12.30mm) requires mechanical panel modification.

Q: What is the impact of the higher current rating on the KB26SKW01-05-EB application?

A: The YB26SKW01-5D05-JD's 3A current rating is backward compatible with applications designed for 1A operation. No circuit redesign is required; the higher rating provides additional design margin and reliability.

Q: Are there compatibility concerns with the LED illumination versus incandescent illumination?

A: LED illumination operates at 5VDC while the original part uses incandescent illumination at 5VAC. The illumination circuit must be evaluated to confirm DC voltage availability. LED illumination typically offers longer operational life and lower power consumption compared to incandescent technology.

Q: Does the panel cutout size difference affect mechanical compatibility?

A: The YB26SKW01-5D05-JD requires a 16.00mm diameter panel cutout compared to the 12.30mm requirement of the KB26SKW01-05-EB. Existing panel assemblies designed for the original part will require mechanical modification to accommodate the larger cutout diameter.

Q: Is the YB26SKW01-5D05-JD suitable for long-term production use?

A: Yes. The YB26SKW01-5D05-JD is classified as active product status, ensuring ongoing manufacturing availability and supply chain support. The extended mechanical life (200,000 cycles) and electrical life (100,000 cycles) exceed the original part specifications.
