Substitute Part Grouping Explanation

Substitute parts for the IUG6-1-72-5.00-A-21 are qualified based on the following critical parameters:

• Current Rating: 15A (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Voltage Rating - DC: 80 V (exact match required)
• Breaker Type: Magnetic (Hydraulic Delay) (exact match required)
• Number of Poles: 1 (exact match required)
• Actuator Type: Lever (exact match required)
• Mounting Type: Panel Mount (exact match required)

Parts meeting all these criteria are functionally equivalent and may be substituted in applications where the IUG6-1-72-5.00-A-21 is specified. Differences in series designation (IUG vs. IEG) and base product numbers reflect manufacturer product line evolution while maintaining electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the IUG6-1-72-5.00-A-21 and IEG6-1-53-15.0-91-V are active products from Sensata-Airpax with RoHS compliance and identical electrical and mechanical specifications. The IEG6-1-53-15.0-91-V includes additional approval certifications (CSA, TUV, UL1077), which may be required for specific regulatory or application requirements. Selection between these parts should be based on certification requirements, supply chain considerations, and application-specific compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can the IEG6-1-53-15.0-91-V replace the IUG6-1-72-5.00-A-21 in existing designs?

A: Yes. Both parts share identical electrical ratings (15A, 250 V AC, 80 V DC), breaker type (magnetic hydraulic delay), pole configuration (single-pole), actuator type (lever), and mounting method (panel mount). They are functionally equivalent for overcurrent protection applications.

Q: What is the significance of the different series designations (IUG vs. IEG)?

A: Series designation reflects the manufacturer's product line classification. Both IUG and IEG series are produced by Sensata-Airpax and meet the same electrical and mechanical performance standards for this application class.

Q: Are there differences in regulatory approvals between these parts?

A: The IEG6-1-53-15.0-91-V carries CSA, TUV, and UL1077 certifications. If your application requires specific regulatory approvals, verify that the selected part meets those requirements before substitution.

Q: Does inventory availability affect substitution decisions?

A: Inventory levels may influence procurement timelines and supply chain planning. The IEG6-1-53-15.0-91-V currently has higher inventory (1012 units vs. 734 units), which may provide supply chain advantages.

Q: Are both parts RoHS compliant?

A: Yes. Both the IUG6-1-72-5.00-A-21 and IEG6-1-53-15.0-91-V are RoHS compliant with MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
