Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MM1-B-34-620-1-2DB-B-C are qualified based on the following critical parameters that must match exactly:

• 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: 1
• Illumination: None

All identified substitute parts meet these electrical and mechanical specifications. Substitution is valid when the replacement part maintains identical ratings and functional characteristics across all listed parameters. Regulatory compliance certifications may vary between manufacturers but do not affect electrical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and are manufactured by Sensata-Airpax or Sensata Technologies – Airpax, established suppliers of circuit protection components. The MM1-B-34-620-1-2DB-B-C carries CCC, CSA, and UL1077 certifications. Substitute parts carry certifications including CSA, TUV, and UL1077, with the exception of IEL1-1-51-20.0-01-V and IUG1-1-62-30.0-CQ-01, which do not list specific approval agencies in the provided data.

All substitute parts are RoHS Compliant or ROHS3 Compliant and carry Moisture Sensitivity Level 1 (Unlimited) ratings where specified. Selection between substitute parts should be based on availability, packaging requirements (Bulk or standard), and specific regulatory certifications required for the end application.

Frequently Asked Questions (FAQ)

Q: Can IEL1-1-51-20.0-01-V be used as a direct replacement for MM1-B-34-620-1-2DB-B-C?

A: Yes. Both parts share identical electrical ratings (20A, 250V AC, 80V DC), breaker type (Magnetic Hydraulic Delay), mounting configuration (Panel Mount), and actuator type (Lever). Both are Active status products.

Q: What is the difference between the IEG1 and IEG6 series substitutes?

A: Both IEG1-1-63-20.0-01-V and IEG6-1-72-20.0-01-V meet all electrical and mechanical parameters for substitution. The difference lies in series designation and internal design, but electrical interchangeability is maintained. Both carry CSA, TUV, and UL1077 certifications.

Q: Are there packaging differences between substitute parts?

A: Yes. Most substitute parts are supplied in Bulk packaging. The original MM1-B-34-620-1-2DB-B-C and IUG1-1-62-30.0-CQ-01 do not specify packaging type in the provided data. Confirm packaging requirements with procurement specifications.

Q: Do all substitute parts carry the same regulatory certifications as the original?

A: No. The original MM1-B-34-620-1-2DB-B-C carries CCC, CSA, and UL1077 certifications. Substitute parts carry varying certifications: IEG1, IEG6, and IELK1 carry CSA, TUV, and UL1077; IEL1 and IUG1 do not list specific approval agencies. Verify certification requirements for your application.

Q: What is the inventory status of substitute parts?

A: All substitute parts are listed as New Original In Stock with quantities ranging from 919 to 1212 pieces, compared to 908 pieces for the original MM1-B-34-620-1-2DB-B-C.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts are either RoHS Compliant or ROHS3 Compliant. The original MM1-B-34-620-1-2DB-B-C is ROHS3 Compliant.
