Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB26SKW01-05-CB is determined by the following critical parameters:

Electrical Compatibility Requirements:

• DPDT circuit configuration (dual-pole, dual-throw)
• On-On switch function
• Minimum 1A current rating at 125V AC and 30V DC
• Red illumination output
• 5V illumination supply voltage compatibility

Mechanical Compatibility Requirements:

• Panel mount, front installation capability
• Circular panel cutout accommodation
• Solder lug or compatible termination for circuit integration
• Operating temperature range of -25°C to 50°C

Regulatory Compliance:

• ROHS3 compliance
• REACH compliance status

The YB26SKW01-5C05-JC meets these substitution criteria through equivalent electrical ratings, identical circuit topology, and compatible mechanical mounting specifications, while offering enhanced performance characteristics in mechanical and electrical life cycles.

Parameter Comparison

Engineering Selection Recommendations

The YB26SKW01-5C05-JC serves as a functional equivalent for the obsolete KB26SKW01-05-CB based on matching electrical specifications and circuit topology. Both components maintain ROHS3 compliance and identical voltage ratings across AC and DC operating conditions.

Key considerations for selection:

Current Rating: The substitute part provides 3A capacity, exceeding the original 1A requirement. This higher rating is compatible with circuits designed for 1A operation and provides additional margin for system reliability.

Panel Cutout Diameter: The substitute requires a 16.00mm circular cutout compared to the original 12.30mm specification. Panel modification is necessary for mechanical installation.

Illumination Technology: The substitute employs LED illumination at 5VDC, replacing the incandescent 5VAC design. Circuit modifications to the illumination supply may be required depending on existing power distribution architecture.

Termination Style: The substitute offers solder and quick-connect 0.110" (2.8mm) termination options, providing flexibility for circuit integration compared to the original solder lug configuration.

Product Availability: The substitute is currently in active production status with 942 units in stock, ensuring supply continuity for new designs and replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the YB26SKW01-5C05-JC directly replace the KB26SKW01-05-CB without modifications?

A: Electrical and functional compatibility is confirmed. Mechanical installation requires panel cutout enlargement from 12.30mm to 16.00mm diameter. Illumination circuit modification is necessary to accommodate the transition from 5VAC incandescent to 5VDC LED operation.

Q: What is the impact of the higher 3A current rating on system design?

A: The 3A rating of the substitute part is compatible with circuits designed for 1A operation. No circuit redesign is required; the higher rating provides additional operational margin and does not affect performance in lower-current applications.

Q: Are there termination compatibility considerations?

A: The original part uses solder lug termination. The substitute offers both solder and quick-connect 0.110" (2.8mm) options. Solder termination is compatible with the original circuit layout; quick-connect termination requires connector accommodation.

Q: How does the LED illumination differ from the original incandescent design?

A: LED illumination operates at 5VDC with extended life characteristics (200,000 mechanical cycles vs. 100,000 for the original). Incandescent operation at 5VAC requires AC power supply; LED operation requires DC power supply. Brightness and color output may differ; application-specific evaluation is necessary.

Q: What are the mechanical life improvements in the substitute part?

A: The YB26SKW01-5C05-JC provides 200,000 mechanical cycles and 100,000 electrical cycles compared to 100,000 and 50,000 cycles respectively for the original part. This represents a 2x improvement in mechanical durability and a 2x improvement in electrical cycle life.

Q: Are both parts compliant with current regulatory standards?

A: Both the KB26SKW01-05-CB and YB26SKW01-5C05-JC maintain ROHS3 compliance. The substitute part is currently in active production, ensuring ongoing compliance with evolving regulatory requirements.
