Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB2011LS1W03-BA is determined by the following critical parameters:

• Circuit configuration (SPDT)
• Current rating (6A AC minimum / 3A DC minimum)
• Voltage rating (125V AC minimum / 30V DC minimum)
• Mounting type (Panel Mount, Rear)
• Panel cutout dimensions (6.50mm circular)
• Actuator type (Round, Button)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)
• RoHS compliance status

The substitute part MBN15LS1W03-BA is classified as a compatible alternative based on matching electrical specifications and mechanical mounting requirements within the NKK Switches product portfolio.

Parameter Comparison

Engineering Selection Recommendations

The MB2011LS1W03-BA is obsolete and no longer in active production. The MBN15LS1W03-BA is listed as the manufacturer-recommended substitute and maintains active product status with NKK Switches. Both components are manufactured by the same supplier, ensuring design continuity and quality standards.

When selecting between these parts, consider the following:

• The substitute part (MBN15LS1W03-BA) is currently available in production quantities (1027 pcs in stock) versus the main part which is obsolete.
• The mounting configuration differs: the main part uses panel mount rear installation, while the substitute uses bushing mount. Physical panel integration requirements must be evaluated for compatibility.
• Verify that the bushing mount configuration of the substitute part accommodates the existing panel cutout and mechanical installation constraints of your application.

Frequently Asked Questions (FAQ)

Q: Can MBN15LS1W03-BA directly replace MB2011LS1W03-BA in all applications?

A: Both parts are SPDT pushbutton switches from NKK Switches with the same part number suffix (-BA). However, the mounting type differs: the original uses panel mount rear installation while the substitute uses bushing mount. Physical compatibility depends on your panel configuration and available space for bushing mount installation.

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

A: Panel mount rear installation secures the switch from behind the panel with a threaded rear connection. Bushing mount uses a threaded bushing that passes through the panel cutout. These require different panel preparation and installation procedures.

Q: Are the electrical specifications identical between these parts?

A: The input data specifies complete electrical parameters only for the main part (MB2011LS1W03-BA). The substitute part (MBN15LS1W03-BA) electrical specifications are not provided in the available documentation. Consult the manufacturer datasheet for complete electrical parameter verification before substitution.

Q: Why is the main part obsolete?

A: Product obsolescence is determined by the manufacturer. The substitute part MBN15LS1W03-BA is the active replacement offering from NKK Switches for this application category.

Q: What packaging is available for the substitute part?

A: The MBN15LS1W03-BA is available in bulk packaging with 1027 pieces currently in stock.
