Key Parameters

Substitute Part Grouping Explanation

The YB26CKW01-5C-JC qualifies as a substitute based on the following alignment with allowed electrical and mechanical parameters:

Matching Parameters:

• DPDT circuit configuration and On-On switch function
• 125V AC voltage rating (primary operating voltage)
• 30V DC voltage rating
• Panel mount, front configuration with round button actuator
• Red LED illumination at 1.9 VDC nominal
• Operating temperature range of -25°C to 50°C
• ROHS3 compliance and identical HTSUS classification

Differing Parameters:

• Current rating increased from 1A to 3A (higher capacity, backward compatible)
• Mechanical life extended from 100,000 to 200,000 cycles
• Electrical life extended from 50,000 to 100,000 cycles
• Panel cutout diameter increased from 12.30mm to 16.00mm (requires panel modification)
• Termination style changed from solder lug to solder with quick connect 0.110" (2.8mm)
• Product status changed from obsolete to active

Parameter Comparison

Engineering Selection Recommendations

The YB26CKW01-5C-JC is electrically compatible with the KB26CKW01-5C-JC for applications operating at or below 1A. The substitute part maintains identical voltage ratings, circuit topology, and illumination specifications while providing enhanced mechanical and electrical life ratings. Both components meet ROHS3 compliance and REACH requirements.

Physical integration requires consideration of the increased panel cutout diameter (16.00mm versus 12.30mm), necessitating panel modification for direct replacement. Termination style differs, requiring wiring harness adaptation from solder lug to quick connect 0.110" (2.8mm) configuration. The active product status of the YB26CKW01-5C-JC ensures ongoing availability and supply chain continuity compared to the obsolete KB26CKW01-5C-JC.

Frequently Asked Questions (FAQ)

Q: Can the YB26CKW01-5C-JC directly replace the KB26CKW01-5C-JC without modification?

A: Electrical substitution is valid for circuits operating at 1A or below. Physical installation requires panel cutout enlargement from 12.30mm to 16.00mm diameter and wiring harness reconfiguration to accommodate the quick connect termination style.

Q: What is the significance of the increased current rating from 1A to 3A?

A: The higher current rating provides design margin and backward compatibility. Circuits designed for 1A operation remain fully functional with the 3A-rated substitute component.

Q: Are the voltage ratings identical between both parts?

A: Yes. Both components are rated for 125V AC and 30V DC, maintaining identical electrical operating parameters.

Q: What compliance certifications apply to both parts?

A: Both the KB26CKW01-5C-JC and YB26CKW01-5C-JC are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code 8536.50.9033.

Q: How do the mechanical and electrical life ratings compare?

A: The YB26CKW01-5C-JC provides doubled mechanical life (200,000 versus 100,000 cycles) and doubled electrical life (100,000 versus 50,000 cycles), extending component service intervals.

Q: What termination differences exist between these parts?

A: The KB26CKW01-5C-JC uses solder lug termination, while the YB26CKW01-5C-JC combines solder with quick connect 0.110" (2.8mm) connectors, requiring harness redesign for substitution.
