Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB2085LS1W03-BA is determined by the following critical parameters:

• Circuit Configuration: DPDT topology must be maintained
• Switch Function: On-On switching behavior required
• Current and Voltage Ratings: AC 6A at 125V and DC 3A at 30V minimum
• Mounting Type: Panel mount rear installation capability
• Actuator Type: Round button actuator
• Termination Style: PC pin termination
• Panel Cutout Dimensions: Circular 6.50mm diameter compatibility
• Environmental Compliance: ROHS3 compliance and MSL 1 rating

The substitute part MBN22LS1W03-BA is identified as an equivalent based on matching these core electrical and mechanical parameters within the NKK Switches product portfolio.

Parameter Comparison

Engineering Selection Recommendations

The MB2085LS1W03-BA is classified as obsolete, necessitating component substitution for new procurements and system maintenance. The MBN22LS1W03-BA is an active product from the same manufacturer with equivalent electrical specifications: matching DPDT circuit configuration, On-On switching function, 6A AC at 125V and 3A DC at 30V ratings, round button actuator, and PC pin termination.

Both components maintain ROHS3 compliance and MSL 1 moisture sensitivity rating, ensuring compatibility with current manufacturing and environmental standards. The primary distinction is the mounting configuration: the main part specifies panel mount rear installation, while the substitute utilizes bushing mount technology. This difference requires mechanical evaluation during integration to confirm panel cutout and mounting hardware compatibility within the target application.

Frequently Asked Questions (FAQ)

Q: Can MBN22LS1W03-BA directly replace MB2085LS1W03-BA in existing designs?

A: Electrical compatibility is confirmed through matching DPDT configuration, On-On function, and identical current/voltage ratings. Mechanical compatibility depends on the mounting interface. The main part uses panel mount rear installation with a 6.50mm circular cutout, while the substitute uses bushing mount technology. Panel geometry and mounting hardware must be evaluated for the specific application.

Q: What are the critical parameters for substitution?

A: Circuit configuration (DPDT), switch function (On-On), current ratings (6A AC, 3A DC), voltage ratings (125V AC, 30V DC), actuator type (round button), and termination style (PC pin) must be maintained. Mounting type and panel cutout dimensions require mechanical assessment.

Q: Are both parts compliant with current standards?

A: Yes. Both MB2085LS1W03-BA and MBN22LS1W03-BA are ROHS3 compliant with MSL 1 moisture sensitivity rating, meeting current environmental and manufacturing standards.

Q: Why is the main part obsolete?

A: The MB2085LS1W03-BA is classified as obsolete by the manufacturer. The MBN22LS1W03-BA is an active product offering equivalent electrical functionality with updated mounting technology.

Q: What is the difference between panel mount rear and bushing mount?

A: Panel mount rear installation uses a rear-mounted mechanism with a defined panel cutout (6.50mm circular). Bushing mount uses a threaded or snap-fit bushing for panel integration. The specific mounting method affects panel preparation and installation procedures.
