Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict parametric equivalence across all electrical and mechanical specifications. The following parameters must match identically between the main part and any substitute:

• 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 criteria. Substitute parts are sourced from Sensata-Airpax, a qualified alternative manufacturer. Each substitute maintains Active product status and RoHS compliance. Approval agencies vary by substitute model but include CSA, TUV, and UL1077 certifications.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are qualified equivalents based on parametric matching and compliance certifications. Selection among substitute options is determined by approval agency requirements and packaging specifications:

IEG11-1-62F-20.0-A-00 (Sensata-Airpax): Approved to CSA and UL1077. Bulk packaging. Suitable for applications requiring CSA or UL1077 certification.

IEGH11-1-72-20.0-01-V (Sensata-Airpax): Approved to CSA, TUV, and UL1077. Bulk packaging. Suitable for applications requiring TUV compliance in addition to CSA and UL1077.

IEGS66-1-61-20.0-A-41-V (Sensata Technologies – Airpax): Approved to CSA, TUV, and UL1077. Suitable for applications requiring TUV compliance.

IELHK11-1-72-20.0-01-V (Sensata-Airpax): Approved to UL1077. Bulk packaging. Suitable for applications requiring UL1077 certification only.

IUG66-1-61-10.0-CQ-01 (Sensata-Airpax): Bulk packaging. Suitable for general applications without specific agency restrictions.

IUG66-1-61-30.0-C-01 (Sensata-Airpax): Bulk packaging. Suitable for general applications without specific agency restrictions.

All substitute parts maintain Moisture Sensitivity Level (MSL) 1 (Unlimited) and identical ECCN and HTSUS classifications to the main part.

Frequently Asked Questions (FAQ)

Q: Can MM2-B-34-620-1-2BA-B-E be directly replaced with any of the listed substitutes?

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 substitution is supported from an electrical and mechanical standpoint.

Q: What is the difference between the substitute parts?

A: Substitute parts differ by manufacturer series designation (IEG, IEGH, IEGS, IEL, IUG) and approval agency certifications. All maintain identical functional specifications. Selection is based on compliance requirements and packaging availability.

Q: Are all substitutes RoHS compliant?

A: Yes. The main part is ROHS3 Compliant. All substitute parts are RoHS Compliant, meeting environmental regulatory requirements.

Q: What approval agencies are represented across the substitute parts?

A: Substitute parts carry certifications from CSA, TUV, and UL1077. The main part carries CCC, CSA, TUV, and UL approvals. Specific agency combinations vary by substitute model.

Q: Does packaging type affect substitution eligibility?

A: Packaging type (Bulk or standard) does not affect electrical or mechanical compatibility. Packaging selection is determined by procurement and inventory management requirements, not functional equivalence.

Q: Are all substitute parts currently in stock?

A: Yes. All substitute parts are listed as New Original In Stock with inventory quantities ranging from 736 to 903 pieces.

Q: What is the ECCN and HTSUS classification for these parts?

A: All parts, including the main part and all substitutes, share identical ECCN classification (EAR99) and HTSUS code (8536.20.0020).
