Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MM2-B-34-620-1-2JB-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 packaging do not affect functional interchangeability when core parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and are RoHS compliant, ensuring continued availability and environmental regulatory adherence. The MM2-B-34-620-1-2JB-B-C carries CCC, CSA, and UL1077 certifications. When selecting substitutes, the following certification coverage applies:

Highest Certification Coverage: IEGH11-1-72-20.0-01-V and IEGS66-1-61-20.0-A-41-V include CSA, TUV, and UL1077 approvals, providing expanded regulatory recognition.

Standard Certification Coverage: IEG11-1-62F-20.0-A-00 includes CSA and UL1077 approvals, covering primary North American and international standards.

Baseline Certification Coverage: IELHK11-1-72-20.0-01-V includes UL1077 approval, meeting core safety standard requirements.

Unspecified Certification: IUG66-1-61-10.0-CQ-01 and IUG66-1-61-30.0-C-01 do not list approval agencies in provided data.

All substitute parts are manufactured by Sensata-Airpax or Sensata Technologies, established suppliers of circuit protection components. Selection should be based on certification requirements for the target application and supply chain availability.

Frequently Asked Questions (FAQ)

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

A: All substitute parts match the critical electrical and mechanical parameters: 20A current rating, 250V AC and 80V DC voltage ratings, magnetic hydraulic delay breaker type, panel mount configuration, lever actuator, and 2-pole design. These parameters define the functional performance and physical compatibility of the circuit breaker in its intended application.

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

A: Yes. The MM2-B-34-620-1-2JB-B-C carries CCC, CSA, and UL1077 certifications. Substitute parts carry varying certification combinations: some include CSA, TUV, and UL1077; others include only CSA and UL1077; and some include only UL1077. Verify that the selected substitute meets the certification requirements of your specific application and regulatory jurisdiction.

Q: Can I use IUG66-1-61-10.0-CQ-01 or IUG66-1-61-30.0-C-01 if approval agencies are not specified?

A: These parts match all electrical and mechanical parameters and are RoHS compliant with Active product status. However, approval agency information is not provided in the available data. Confirm certification status with the manufacturer or supplier before selection for applications requiring specific regulatory approvals.

Q: What is the difference between bulk and standard packaging?

A: Packaging designation (Bulk versus standard) affects order quantity and logistics but does not impact electrical or mechanical performance. Select packaging based on procurement requirements and inventory management practices.

Q: Are all substitute parts currently in stock?

A: Inventory levels are provided for reference: MM2-B-34-620-1-2JB-B-C (898 pcs), IEG11-1-62F-20.0-A-00 (855 pcs), IEGH11-1-72-20.0-01-V (858 pcs), IEGS66-1-61-20.0-A-41-V (899 pcs), IELHK11-1-72-20.0-01-V (736 pcs), IUG66-1-61-10.0-CQ-01 (903 pcs), and IUG66-1-61-30.0-C-01 (876 pcs). Confirm current availability with your supplier.

Q: Can I mix different substitute parts in the same circuit or system?

A: All substitute parts are functionally equivalent and meet identical electrical specifications. However, design consistency and supply chain management typically favor using a single part number throughout a system. Consult system design documentation for any specific requirements regarding component uniformity.
