MB2011SA2W31-BA Equivalent & Substitute Parts

Part Overview

The MB2011SA2W31-BA is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with a rated capacity of 6A at 125V AC and 3A at 30V DC. This through-hole, right-angle mounted component is designed for standard applications requiring momentary switching functionality with an epoxy-sealed PC pin termination. The product is currently obsolete, making identification of suitable substitute components essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB2011SA2W31-BA is determined by electrical and mechanical compatibility across the following critical parameters:

• Circuit Configuration: SPDT topology must be maintained for functional equivalence
• Current and Voltage Ratings: Substitute parts must meet or exceed 6A at 125V AC and 3A at 30V DC specifications
• Mounting Configuration: Through-hole, right-angle orientation is required for mechanical fit
• Termination Style: PC pin termination ensures compatibility with existing PCB layouts
• Switch Function: On-momentary operation must be preserved
• Environmental Compliance: RoHS3 compliance is mandatory for regulatory alignment

The identified substitute part MBN15SA2W31-BA is listed as an NKK Switches component with active product status, providing continuity of supply from the original manufacturer.
