Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB2011SS1W03-BA is determined by the following critical parameters:

• Circuit Configuration: SPDT topology must be maintained
• Current and Voltage Ratings: AC 6A at 125V and DC 3A at 30V minimum
• Mounting Configuration: Panel mount, rear termination with circular 6.50mm diameter cutout
• Actuator Specification: Round button actuator, black color
• Termination Type: PC pin with epoxy sealed terminals
• Environmental Compliance: ROHS3 compliance and operating temperature range -30°C to 85°C
• Mechanical Durability: Minimum 100,000 mechanical cycles and 25,000 electrical cycles

The identified substitute part MBN15SS1W03-BA shares the core electrical specifications and termination characteristics required for direct functional replacement in legacy applications.

Parameter Comparison

Engineering Selection Recommendations

The MB2011SS1W03-BA is classified as obsolete. The MBN15SS1W03-BA is the active equivalent from NKK Switches and maintains identical electrical ratings (6A at 125V AC, 3A at 30V DC) and SPDT circuit configuration. Both components are manufactured by the same supplier and share PC pin termination with epoxy sealed terminals.

Selection of MBN15SS1W03-BA is appropriate for applications requiring direct replacement of the obsolete MB2011SS1W03-BA, provided that mechanical mounting and panel cutout dimensions are compatible with the bushing mount configuration of the substitute part. The active product status of MBN15SS1W03-BA ensures continued availability and supply chain reliability for new installations and legacy system repairs.

Frequently Asked Questions (FAQ)

Q: Can MBN15SS1W03-BA directly replace MB2011SS1W03-BA in existing applications?

A: MBN15SS1W03-BA shares identical electrical specifications (SPDT, 6A at 125V AC, 3A at 30V DC) and PC pin termination. Compatibility depends on mechanical mounting configuration. The main part uses panel mount, rear termination with a 6.50mm circular cutout, while the substitute uses bushing mount. Physical panel dimensions and mounting hardware must be evaluated for compatibility.

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

A: Panel mount, rear termination secures the switch from the rear of the panel with terminals extending backward. Bushing mount uses a threaded bushing that secures the switch through the panel opening. These mounting methods require different panel preparation and may not be interchangeable without mechanical modification.

Q: Are both parts RoHS compliant?

A: MB2011SS1W03-BA is ROHS3 compliant. RoHS compliance status for MBN15SS1W03-BA is not specified in the provided data and should be confirmed with the manufacturer before selection for applications with RoHS requirements.

Q: What is the inventory status for these parts?

A: MB2011SS1W03-BA has 971 pieces in stock as new original inventory. MBN15SS1W03-BA has 807 pieces in stock as new original inventory in bulk packaging. Both components are available for immediate sourcing.

Q: Are the mechanical and electrical life ratings identical?

A: Mechanical and electrical life specifications for MBN15SS1W03-BA are not provided in the available data. These parameters should be confirmed with the manufacturer's technical documentation before final component selection.
