Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB2011SA2G31-BE is determined by the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Momentary)
• Current and voltage ratings (0.4VA at 28V AC/DC)
• Mounting type (Through Hole, Right Angle)
• Actuator type and color (Round Button, Yellow)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)
• Mechanical and electrical life specifications

The identified substitute part MBN15SA2G31-BE is listed as an NKK Switches alternative within the manufacturer's product portfolio. Substitution eligibility is based on matching these electrical and mechanical parameters to ensure functional compatibility in the target application.

Parameter Comparison

Engineering Selection Recommendations

The MB2011SA2G31-BE is obsolete; therefore, the MBN15SA2G31-BE is the designated NKK Switches alternative for new designs and system replacements. The main part maintains ROHS3 compliance and MSL 1 rating, both of which support long-term storage and handling without moisture sensitivity constraints.

Selection of the substitute part should be based on:

• Active product status of MBN15SA2G31-BE, ensuring ongoing availability and manufacturer support
• Confirmation that both parts are manufactured by NKK Switches, maintaining supply chain consistency
• Availability of both parts in bulk packaging with current inventory levels
• Compliance certifications of the main part (ROHS3, REACH Unaffected, EAR99 classification) as baseline requirements

Frequently Asked Questions (FAQ)

Q: Why is the MB2011SA2G31-BE classified as obsolete? A: The MB2011SA2G31-BE is no longer in active production by NKK Switches. The MBN15SA2G31-BE is the active alternative within the manufacturer's current product line.

Q: What are the critical parameters for substitution? A: Substitution requires matching circuit configuration (SPDT), switch function (On-Momentary), current/voltage ratings (0.4VA at 28V AC/DC), mounting type (Through Hole, Right Angle), actuator specifications (Round Button, Yellow), and termination style (PC Pin).

Q: Are both parts available in the same packaging format? A: Both the MB2011SA2G31-BE and MBN15SA2G31-BE are supplied in bulk packaging, supporting equivalent procurement and inventory management processes.

Q: What compliance certifications apply to these parts? A: The MB2011SA2G31-BE is ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Compliance status for the substitute part should be confirmed with the manufacturer or authorized distributor.

Q: What is the mechanical life expectancy? A: The MB2011SA2G31-BE is rated for 100,000 mechanical cycles and 50,000 electrical cycles, establishing baseline durability expectations for equivalent alternatives.
