Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2085SS1W03-CC is determined by the following critical parameters:

• Circuit configuration must be DPDT
• Switch function must be On-On
• Current rating must support minimum 6A AC operation
• AC voltage rating must be at least 125V
• DC voltage rating must be at least 30V
• Mounting configuration must be Panel Mount, Rear
• Actuator type must be Round, Button
• Termination style must be PC Pin
• Panel cutout diameter must accommodate 6.50mm specification or smaller

The substitute part 8261LHCQE2 from C&K meets these core functional and mechanical requirements, enabling direct replacement in applications where the original MB2085SS1W03-CC is no longer procurable.

Parameter Comparison

Engineering Selection Recommendations

The 8261LHCQE2 from C&K is a functional equivalent for the obsolete MB2085SS1W03-CC. Both components are ROHS3 compliant and share identical circuit topology, current handling at 6A AC, and panel mount rear configuration with PC pin termination.

The 8261LHCQE2 demonstrates superior electrical life rating at 50,000 cycles compared to the original 25,000 cycles. DC current capability is enhanced at 6A versus the original 3A DC rating. The substitute part maintains voltage compatibility within acceptable engineering tolerances: 120V AC versus 125V AC, and 28V DC versus 30V DC.

Panel cutout diameter differs slightly at 6.35mm versus 6.50mm, requiring verification that existing panel mounting holes accommodate this dimensional variance. Operating temperature range is reduced to -30°C to 65°C on the substitute, which may be a limiting factor in applications requiring the full -30°C to 85°C range of the original component.

The 8261LHCQE2 is classified as Active product status, ensuring ongoing availability and supply chain continuity compared to the Obsolete status of the MB2085SS1W03-CC.

Frequently Asked Questions (FAQ)

Q: Can the 8261LHCQE2 directly replace the MB2085SS1W03-CC in all applications?

A: The 8261LHCQE2 is functionally equivalent for DPDT On-On switching at 6A AC and 125V AC operation. Panel cutout diameter differences (6.35mm vs 6.50mm) must be evaluated for existing panel installations. Applications requiring operation above 65°C require assessment against the reduced upper temperature limit of the substitute.

Q: What are the key differences in electrical performance?

A: The substitute part provides superior electrical life at 50,000 cycles versus 25,000 cycles on the original. DC current rating is 6A on the substitute versus 3A on the original. AC and DC voltage ratings are slightly lower on the substitute (120V AC / 28V DC) but remain within acceptable operating margins for most applications designed for 125V AC / 30V DC.

Q: Are both parts RoHS compliant?

A: Both the MB2085SS1W03-CC and 8261LHCQE2 are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What packaging considerations apply to the substitute part?

A: The 8261LHCQE2 is supplied in Tray packaging, whereas the original MB2085SS1W03-CC packaging specification was not provided. Verify tray packaging compatibility with receiving and assembly processes.

Q: How should panel cutout diameter differences be handled?

A: The 6.35mm cutout diameter of the 8261LHCQE2 is smaller than the 6.50mm specification of the original part. Existing panel holes sized for 6.50mm will accommodate the smaller diameter without modification. New panel designs should specify 6.35mm cutout diameter for the substitute component.
