Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MM2-B-34-620-1-2CB-B-C are qualified based on strict parametric equivalence across the following criteria:

Electrical Specifications: Current rating of 20A, AC voltage rating of 250V, and DC voltage rating of 80V must match exactly.

Mechanical Configuration: Panel mount installation type, lever actuator mechanism, and 2-pole configuration must be identical.

Functional Characteristics: Magnetic hydraulic delay trip mechanism must be present in all substitute parts.

Regulatory Compliance: All substitute parts must maintain active product status and RoHS compliance certification.

All six substitute parts listed meet these criteria and are therefore classified as parametric equivalents suitable for direct replacement in applications requiring the MM2-B-34-620-1-2CB-B-C specifications.

Parameter Comparison

Engineering Selection Recommendations

All six substitute parts are qualified as direct parametric equivalents to the MM2-B-34-620-1-2CB-B-C based on identical electrical ratings, mechanical configuration, and active product status.

Sensata-Airpax IEG Series (IEG11-1-62F-20.0-A-00, IEGH11-1-72-20.0-01-V, IEGS66-1-61-20.0-A-41-V): These parts maintain full compliance with CSA and UL1077 certifications. IEGH11-1-72-20.0-01-V and IEGS66-1-61-20.0-A-41-V include TUV certification in addition to CSA and UL1077. All three IEG series parts carry MSL rating of 1 (Unlimited).

Sensata-Airpax IEL Series (IELHK11-1-72-20.0-01-V): This part maintains UL1077 certification with MSL rating of 1 (Unlimited). Approval agency coverage is limited to UL1077 compared to the broader certification scope of IEG series alternatives.

Sensata-Airpax IUG Series (IUG66-1-61-10.0-CQ-01, IUG66-1-61-30.0-C-01): These parts do not list specific approval agencies in the provided data. Both carry MSL rating of 1 (Unlimited).

Selection among substitute parts should be based on application-specific regulatory requirements and approval agency mandates. All parts are in active production with adequate inventory availability.

Frequently Asked Questions (FAQ)

Q: What makes these parts equivalent to the MM2-B-34-620-1-2CB-B-C?

A: All substitute parts match the critical electrical specifications (20A, 250V AC, 80V DC), mechanical configuration (panel mount, lever actuator, 2-pole), and functional characteristics (magnetic hydraulic delay trip mechanism). These parameters define functional interchangeability for circuit protection applications.

Q: Can I use any of these substitute parts interchangeably?

A: Yes, all six substitute parts are parametric equivalents and can be used as direct replacements. However, application-specific regulatory requirements may dictate preference for parts with particular approval agency certifications (CSA, TUV, UL1077).

Q: What is the difference between the IEG, IEL, and IUG series?

A: These represent different product series from Sensata-Airpax. All three series contain parts that meet the electrical and mechanical specifications of the MM2-B-34-620-1-2CB-B-C. Series designation reflects internal product architecture and design lineage but does not affect functional equivalence for this application.

Q: Are there packaging differences among the substitute parts?

A: The main part (MM2-B-34-620-1-2CB-B-C) is specified with packaging designation "-". Most substitute parts are packaged in Bulk format. IEGS66-1-61-20.0-A-41-V also carries packaging designation "-". Packaging format does not affect electrical or mechanical performance.

Q: What does MSL 1 (Unlimited) mean?

A: MSL (Moisture Sensitivity Level) 1 indicates the component has unlimited shelf life under standard storage conditions without requiring special moisture control measures. All substitute parts carry this rating.

Q: Which substitute part has the broadest regulatory approval?

A: IEGH11-1-72-20.0-01-V and IEGS66-1-61-20.0-A-41-V both carry CSA, TUV, and UL1077 certifications, providing the broadest approval agency coverage among the substitute options.

Q: Is RoHS compliance maintained across all parts?

A: Yes. The main part carries RoHS3 Compliant status. All six substitute parts carry RoHS Compliant status, ensuring environmental regulatory compliance across all options.
