Key Parameters

Substitute Part Grouping Explanation

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

Electrical Parameters: Circuit configuration (SPDT), current rating (6A AC / 3A DC minimum), and voltage rating (125V AC / 30V DC minimum) must be maintained or exceeded in any substitute part.

Mechanical Parameters: Mounting type (through-hole, right-angle orientation), actuator type (round button), and termination style (PC pin) establish physical compatibility with existing PCB designs and panel cutouts.

Environmental & Compliance Parameters: Operating temperature range (-30°C to 85°C), mechanical life (100,000 cycles), and RoHS3 compliance ensure functional equivalence in the intended application environment.

The substitute part MBN15SA2W31-CC is listed as a manufacturer-recommended alternative by NKK Switches, indicating direct functional equivalence within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

The MB2011SA2W31-CC is an obsolete product with 1,084 units currently in stock. For new designs or long-term supply assurance, the MBN15SA2W31-CC is designated as the manufacturer-recommended substitute and carries active product status, ensuring continued availability and support.

Both parts are manufactured by NKK Switches and maintain ROHS3 compliance. The transition from the obsolete MB2011SA2W31-CC to the active MBN15SA2W31-CC is supported by NKK Switches as a direct functional replacement, with 866 units available in bulk packaging.

Selection between these parts should prioritize the active product (MBN15SA2W31-CC) for new applications and ongoing production to avoid future obsolescence-related supply constraints.

Frequently Asked Questions (FAQ)

Q: What makes MBN15SA2W31-CC a suitable substitute for MB2011SA2W31-CC?

A: MBN15SA2W31-CC is designated by NKK Switches as the manufacturer-recommended replacement. Both parts share the same manufacturer and are designed to provide equivalent electrical and mechanical function within the MB2000 series pushbutton switch family.

Q: Can I use MBN15SA2W31-CC as a direct drop-in replacement on existing PCBs designed for MB2011SA2W31-CC?

A: Physical and electrical compatibility depends on matching mounting type, termination style, and circuit configuration. Consult the detailed datasheets for both parts to confirm dimensional and electrical specifications before implementation.

Q: Why is the MB2011SA2W31-CC classified as obsolete?

A: Obsolescence indicates that the manufacturer has discontinued active production and support. NKK Switches has transitioned this product line to the active MBN15SA2W31-CC variant to consolidate product offerings and improve supply chain efficiency.

Q: What is the difference between bulk and standard packaging for these parts?

A: Packaging designation (bulk vs. standard) affects order quantities, handling, and storage requirements but does not alter electrical or mechanical specifications. Confirm packaging requirements with your procurement process.

Q: Are both parts RoHS3 compliant?

A: The MB2011SA2W31-CC is confirmed ROHS3 compliant. RoHS compliance status for MBN15SA2W31-CC should be confirmed through the manufacturer's current datasheet or compliance documentation.
