Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the MB2011SA2G31-CA is determined by the following critical parameters:

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

The identified substitute part MBN15SA2G31-CA is manufactured by NKK Switches and maintains compatibility within the MB2000 series family. Substitution is valid when all electrical parameters, mechanical mounting characteristics, and environmental specifications align with the original component requirements.

Parameter Comparison

Engineering Selection Recommendations

The MB2011SA2G31-CA is classified as obsolete, necessitating substitute component identification for replacement applications. The MBN15SA2G31-CA is listed as an active product from the same manufacturer (NKK Switches), indicating ongoing availability and support.

Selection of substitute components should be based on:

• Confirmation that electrical specifications (voltage, current, circuit configuration) match application requirements
• Verification that mechanical mounting and termination characteristics are compatible with existing PCB layouts
• Confirmation of RoHS and environmental compliance status for the target application
• Availability of complete technical documentation for the substitute part prior to design implementation

The active product status of MBN15SA2G31-CA provides assurance of continued manufacturing support and supply chain availability compared to the obsolete MB2011SA2G31-CA.

Frequently Asked Questions (FAQ)

Q: Why is the MB2011SA2G31-CA classified as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand and production decisions. NKK Switches has designated this component as obsolete, indicating it is no longer in active production.

Q: What are the critical parameters for substituting the MB2011SA2G31-CA?

A: The substitute must maintain SPDT circuit configuration, 0.4VA current rating at 28V AC/DC, momentary on-off function, through-hole right-angle mounting, round button actuator, and PC pin termination. Operating temperature range (-30°C to 85°C) and mechanical/electrical life specifications must also be compatible.

Q: Is the MBN15SA2G31-CA a direct replacement?

A: MBN15SA2G31-CA is identified as a substitute part from NKK Switches. Complete electrical and mechanical specifications for the substitute must be verified against application requirements before implementation.

Q: What is the difference in product status between the main part and substitute?

A: The MB2011SA2G31-CA is obsolete and no longer manufactured. The MBN15SA2G31-CA is active, indicating current production and ongoing manufacturer support.

Q: Are there packaging differences between these parts?

A: The main part is packaged in standard format, while the MBN15SA2G31-CA is supplied in bulk packaging. Packaging selection should be based on procurement volume and inventory management requirements.

Q: What compliance certifications apply to these components?

A: The MB2011SA2G31-CA is ROHS3 compliant and REACH unaffected. Compliance status for the substitute part should be confirmed through the manufacturer's technical documentation.
