Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MM1-B-64-620-1-2DA-B-C are determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Current Rating: 20A
• Voltage Rating - AC: 250V
• Voltage Rating - DC: 80V

Mechanical Parameters:

• Breaker Type: Magnetic (Hydraulic Delay)
• Mounting Type: Panel Mount
• Actuator Type: Lever
• Number of Poles: 1

Functional Parameters:

• Illumination: None

All substitute parts listed below match these parameters exactly. Substitution is valid only when all parameters align with the original specification. Differences in manufacturer, series designation, or regulatory certifications do not affect electrical or mechanical compatibility when the above parameters are identical.

• IUG1-1-62-30.0-CQ-01: No approval agencies specified in provided data

Selection of substitute parts should account for application-specific regulatory requirements. Parts carrying UL1077 and CSA certifications provide direct alignment with the original part's compliance profile. All substitute parts are available in Active status with inventory levels ranging from 919 to 1212 pieces.

Frequently Asked Questions (FAQ)

Q: What determines if a circuit breaker can substitute for the MM1-B-64-620-1-2DA-B-C?

A: Substitution is valid when the following parameters 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), and Illumination (None). All listed substitute parts meet these criteria.

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

A: Yes. The MM1-B-64-620-1-2DA-B-C carries CCC, CSA, and UL1077 certifications. Sensata-Airpax substitutes carry varying certifications: IEG1-1-63-20.0-01-V and IEG6-1-72-20.0-01-V include CSA, TUV, and UL1077; IELK1-1-72-20.0-01-V includes UL1077. Applications requiring specific certifications should be cross-referenced with the substitute part's approval agency list.

Q: Do packaging differences affect substitution compatibility?

A: Packaging format (Bulk versus other specifications) does not affect electrical or mechanical compatibility. Packaging differences relate to order quantity and handling only. The functional performance of the circuit breaker remains identical regardless of packaging configuration.

Q: What is the inventory status of substitute parts?

A: All substitute parts are listed as Active with current inventory: IEL1-1-51-20.0-01-V (919 pcs), IELK1-1-72-20.0-01-V (1212 pcs), IEG1-1-63-20.0-01-V (1051 pcs), IEG6-1-72-20.0-01-V (1032 pcs), and IUG1-1-62-30.0-CQ-01 (1095 pcs).

Q: Can the MM1-B-64-620-1-2DA-B-C be replaced with a different current rating?

A: No. The 20A current rating is a critical parameter. Substitution is limited to parts with identical 20A ratings. Parts with different current ratings are not compatible and do not qualify as substitutes.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are RoHS Compliant. The original MM1-B-64-620-1-2DA-B-C is ROHS3 Compliant. Both compliance levels satisfy RoHS requirements.
