MB2085LS1W03-CC Equivalent & Substitute Parts

Part Overview

The MB2085LS1W03-CC is a pushbutton switch manufactured by NKK Switches, featuring DPDT (Double Pole Double Throw) circuitry with a 6A AC / 3A DC current rating and 125V AC / 30V DC voltage rating. This component is panel-mounted with rear termination and utilizes PC pin connections with epoxy sealed terminals. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2085LS1W03-CC is determined by the following critical parameters:

• Circuit Configuration: DPDT topology is mandatory for functional equivalence
• Switch Function: On-On operation must be maintained
• Current Rating: Minimum 6A AC capability required; DC rating of 3A or higher acceptable
• Voltage Rating: Minimum 125V AC and 30V DC required
• Mounting Type: Panel Mount, Rear configuration required
• Termination Style: PC Pin connections required
• Actuator Type: Round button actuator required
• Panel Cutout Compatibility: Circular cutout diameter within acceptable mechanical tolerance

The identified substitute parts meet these core electrical and mechanical requirements while maintaining compatibility with existing panel mount installations.

Parameter Comparison

Engineering Selection Recommendations

MBN22LS1W03-CC (NKK Switches): This part is manufactured by the same supplier as the original component and carries an active product status, ensuring long-term availability. However, the mounting type differs (bushing mount versus panel mount, rear), which may require mechanical redesign of the panel interface. Electrical specifications are not fully documented in available data.

8261LHCQE2 (C&K): This substitute maintains panel mount, rear configuration with PC pin termination, providing direct mechanical compatibility. The part meets or exceeds the original voltage and current specifications (120V AC / 28V DC with 6A AC/DC rating). The electrical life rating of 50,000 cycles exceeds the original 25,000 cycles. The operating temperature range is reduced to -30°C to 65°C, which may be a limiting factor in high-temperature applications. Both parts are ROHS3 compliant. The panel cutout diameter of 6.35mm is 0.15mm smaller than the original, requiring verification of mechanical fit tolerance.

Frequently Asked Questions (FAQ)

Q: Can MBN22LS1W03-CC be used as a direct replacement for MB2085LS1W03-CC?

A: MBN22LS1W03-CC shares the same manufacturer and part number structure but uses bushing mount configuration instead of panel mount, rear. This requires mechanical redesign of the panel interface and is not a direct drop-in replacement.

Q: Is 8261LHCQE2 mechanically compatible with existing panel cutouts designed for MB2085LS1W03-CC?

A: The panel cutout diameter differs by 0.15mm (6.35mm versus 6.50mm). Verification of mechanical tolerance stack-up is required to confirm fit within existing panel apertures.

Q: What is the impact of the reduced operating temperature range in 8261LHCQE2?

A: The 8261LHCQE2 operates to 65°C maximum, compared to 85°C for the original part. Applications requiring operation above 65°C cannot use this substitute.

Q: Are both substitute parts RoHS compliant?

A: The 8261LHCQE2 is confirmed ROHS3 compliant. Compliance status for MBN22LS1W03-CC is not documented in available specifications.

Q: Which substitute offers superior electrical performance?

A: The 8261LHCQE2 provides higher electrical life (50,000 cycles versus 25,000 cycles) and equal or higher current ratings (6A AC/DC versus 6A AC / 3A DC).
