Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB2085LS1W01-BC is determined by the following critical parameters:

• Circuit configuration must be DPDT
• Switch function must be On-On
• AC current rating must be minimum 6A at 125V
• DC current rating must be minimum 3A at 30V
• Mounting configuration must be Panel Mount, Rear
• Termination must be Solder Lug
• Panel cutout diameter must accommodate 6.50mm specification or smaller
• RoHS3 compliance required

The MPA206N from TE Connectivity ALCOSWITCH Switches meets these substitution criteria with equivalent electrical ratings and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MPA206N is a direct functional equivalent for the MB2085LS1W01-BC. Both components share identical circuit configuration (DPDT), switch function (On-On), and primary electrical ratings (6A at 125V AC). The MPA206N maintains ROHS3 compliance and is currently in active production status, ensuring long-term availability and supply chain continuity.

The MPA206N demonstrates superior electrical life specification (50,000 cycles versus 25,000 cycles) and higher DC current capability (4A versus 3A), providing enhanced performance margins in DC applications. The panel cutout diameter of 6.35mm is compatible with the 6.50mm specification of the original part, requiring no mechanical redesign for panel integration.

Operating temperature range differences (-20°C to 80°C for MPA206N versus -30°C to 85°C for MB2085LS1W01-BC) should be evaluated against specific application requirements. DC voltage rating of 28V on the MPA206N is acceptable for applications rated at 30V DC, maintaining adequate safety margins.

Frequently Asked Questions (FAQ)

Q: Can the MPA206N directly replace the MB2085LS1W01-BC without circuit modification?

A: Yes. Both components feature identical DPDT circuit configuration and On-On switch function with matching AC voltage and current ratings (6A at 125V). Solder lug termination is identical, and panel mounting configuration is compatible.

Q: What are the mechanical compatibility considerations?

A: The MPA206N has a panel cutout diameter of 6.35mm compared to 6.50mm for the MB2085LS1W01-BC. This smaller diameter is compatible with existing 6.50mm panel cutouts. No mechanical redesign is required.

Q: Are there DC application limitations with the MPA206N?

A: The MPA206N is rated for 4A at 28V DC, compared to the original part's 3A at 30V DC. For applications requiring exactly 30V DC operation, the 28V rating should be evaluated against system voltage tolerance specifications. The higher current capability (4A) provides additional margin for DC applications.

Q: What is the significance of the higher electrical life rating on the MPA206N?

A: The MPA206N specifies 50,000 electrical cycles compared to 25,000 cycles for the MB2085LS1W01-BC. This indicates extended operational life expectancy in high-cycle switching applications, providing improved reliability and reduced maintenance frequency.

Q: Are there temperature range considerations for substitution?

A: The MPA206N operates from -20°C to 80°C, while the original part operates from -30°C to 85°C. Applications requiring operation below -20°C or above 80°C should retain the original specification or evaluate alternative components with extended temperature ranges.

Q: Do both components meet current regulatory compliance requirements?

A: Yes. Both the MB2085LS1W01-BC and MPA206N are ROHS3 compliant. The MPA206N is currently in active production status, ensuring compliance with current and future regulatory standards.
