Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MM2-B-34-620-1-2HA-B-C are qualified based on the following critical parameters that must match exactly:

Mandatory Matching Parameters:

• Current Rating: 20A
• Voltage Rating - AC: 250V
• Voltage Rating - DC: 80V
• Breaker Type: Magnetic (Hydraulic Delay)
• Mounting Type: Panel Mount
• Actuator Type: Lever
• Number of Poles: 2
• Illumination: None

All identified substitute parts meet these electrical and mechanical specifications. Substitution is valid when all parameters listed above are identical between the main part and the substitute part. Differences in manufacturer, series designation, or base product number do not affect functional interchangeability when core parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and comply with RoHS regulations. Selection among substitute options should be based on the following factors:

Regulatory Certification Coverage: The MM2-B-34-620-1-2HA-B-C carries CCC, CSA, and UL1077 approvals. Substitute parts carry the following certifications:

• IEG11-1-62F-20.0-A-00: CSA, UL1077
• IEGH11-1-72-20.0-01-V: CSA, TUV, UL1077
• IEGS66-1-61-20.0-A-41-V: CSA, TUV, UL1077
• IELHK11-1-72-20.0-01-V: UL1077
• IUG66-1-61-10.0-CQ-01: No approval agencies specified
• IUG66-1-61-30.0-C-01: No approval agencies specified

Inventory Availability: All substitute parts are available in bulk packaging with inventory levels ranging from 736 to 903 pieces.

Moisture Sensitivity Level: All Sensata-Airpax substitute parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can MM2-B-34-620-1-2HA-B-C be directly replaced with any of the listed substitute parts?

A: Yes. All listed substitute parts are parametric equivalents with identical electrical ratings (20A, 250V AC, 80V DC), breaker type (Magnetic Hydraulic Delay), mounting configuration (Panel Mount), actuator type (Lever), and pole count (2). Direct functional substitution is valid based on matching core specifications.

Q: Are there differences in regulatory approvals between the main part and substitutes?

A: Yes. The main part MM2-B-34-620-1-2HA-B-C carries CCC, CSA, and UL1077 certifications. Substitute parts carry varying certification levels. IEG11-1-62F-20.0-A-00 carries CSA and UL1077. IEGH11-1-72-20.0-01-V and IEGS66-1-61-20.0-A-41-V carry CSA, TUV, and UL1077. IELHK11-1-72-20.0-01-V carries UL1077 only. IUG66-1-61-10.0-CQ-01 and IUG66-1-61-30.0-C-01 have no specified approval agencies. Application requirements must determine acceptable certification levels.

Q: What is the difference between the IUG66 series parts (IUG66-1-61-10.0-CQ-01 and IUG66-1-61-30.0-C-01)?

A: Both IUG66 series parts are parametric equivalents with identical electrical and mechanical specifications. The differences in part number designations (10.0-CQ-01 versus 30.0-C-01) reflect manufacturer-specific coding but do not affect functional performance or interchangeability when all core parameters match.

Q: Is RoHS compliance consistent across all parts?

A: The main part MM2-B-34-620-1-2HA-B-C is ROHS3 Compliant. All substitute parts from Sensata-Airpax are RoHS Compliant. Both designations indicate compliance with RoHS regulations; the specific version designation reflects the regulatory framework applicable at the time of certification.

Q: Are all substitute parts available in bulk packaging?

A: Five of the six substitute parts are specified as Bulk packaging: IEG11-1-62F-20.0-A-00, IEGH11-1-72-20.0-01-V, IELHK11-1-72-20.0-01-V, IUG66-1-61-10.0-CQ-01, and IUG66-1-61-30.0-C-01. IEGS66-1-61-20.0-A-41-V does not specify packaging designation.

Q: What is the Moisture Sensitivity Level (MSL) for the main part?

A: The main part MM2-B-34-620-1-2HA-B-C does not specify an MSL rating. All Sensata-Airpax substitute parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity constraints.
