Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB2011SA2W31-CA is determined by matching the following critical electrical and mechanical parameters:

Electrical Parameters: Circuit configuration (SPDT), current ratings (6A AC / 3A DC minimum), voltage ratings (125V AC / 30V DC minimum), and switch function (On-Momentary).

Mechanical Parameters: Mounting type (through-hole, right-angle orientation), actuator type (round button), termination style (PC pin), and physical form factor compatibility.

Environmental & Compliance Parameters: Operating temperature range (-30°C to 85°C), mechanical life (100,000 cycles), electrical life (25,000 cycles), and RoHS3 compliance.

The substitute part MBN15SA2W31-CA is identified as an equivalent based on functional compatibility within these parameter boundaries.

Parameter Comparison

Engineering Selection Recommendations

The MB2011SA2W31-CA is classified as obsolete, necessitating the use of active alternatives for new procurement and system continuity. The MBN15SA2W31-CA is listed as an active product from the same manufacturer (NKK Switches), providing supply chain continuity. The main part maintains ROHS3 compliance; compliance status for the substitute should be confirmed through the manufacturer's current technical documentation prior to final component selection for applications with regulatory requirements.

Selection between the main part (from existing inventory) and the substitute part should be based on application requirements, availability constraints, and the need for long-term supply assurance. The obsolete status of MB2011SA2W31-CA indicates limited future availability, making the active substitute a prudent choice for new designs and ongoing production requirements.

Frequently Asked Questions (FAQ)

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

A: Both parts are manufactured by NKK Switches and share the same part number suffix structure (-SA2W31-CA), indicating functional and mechanical compatibility within the NKK Switches product family. The substitute is currently in active production status, ensuring supply availability.

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

A: Obsolete status indicates the part is no longer in active production. This classification typically results from product line consolidation, design updates, or market transition. The availability of active alternatives from the same manufacturer supports migration to current product offerings.

Q: Are there any compliance differences between the main part and substitute?

A: The main part is confirmed ROHS3 compliant. Compliance certification for the substitute part should be obtained from NKK Switches technical documentation to ensure compatibility with applications subject to regulatory requirements.

Q: What parameters must match for a pushbutton switch to be considered equivalent?

A: Critical matching parameters include circuit configuration (SPDT), current and voltage ratings (6A AC / 125V AC minimum, 3A DC / 30V DC minimum), switch function (On-Momentary), mounting type (through-hole, right-angle), actuator type (round button), and termination style (PC pin).

Q: Can I use the substitute part in existing PCB designs without modification?

A: Physical and electrical compatibility should be confirmed through detailed comparison of mechanical dimensions, pin configuration, and electrical specifications. Consult NKK Switches technical datasheets for both parts to verify footprint and functional equivalence before PCB implementation.
