Substitute Part Grouping Explanation

Substitution of the IUG6-1-61-20.0-C-01 is determined by strict equivalence across the following critical parameters:

• Breaker Type: Magnetic (Hydraulic Delay)
• Current Rating: 50A
• Voltage Rating - AC: 250V
• Voltage Rating - DC: 80V
• Number of Poles: 1
• Mounting Type: Panel Mount
• Actuator Type: Lever

The substitute part IUG2-28780-1 meets all these requirements identically. Both parts are manufactured by Sensata-Airpax, belong to the IUG series family, maintain RoHS compliance, and share the same moisture sensitivity classification. The substitution is based on functional and electrical equivalence, not on performance assumptions or design improvements.

Parameter Comparison

Engineering Selection Recommendations

Both the IUG6-1-61-20.0-C-01 and IUG2-28780-1 are active production components manufactured by Sensata-Airpax. Selection between these parts should be based on:

• Availability and inventory levels at the time of procurement
• Supply chain lead times and logistics considerations
• Existing component qualification and documentation within your organization
• Compliance requirements specific to your application (both parts are RoHS compliant and carry identical regulatory classifications: ECCN EAR99, HTSUS 8536.20.0020)

The IUG2-28780-1 carries UL1077 approval agency certification, which may be relevant for specific regulatory or application requirements. Both parts are electrically and mechanically equivalent for panel mount circuit protection applications requiring 50A protection at 250V AC or 80V DC with lever-actuated magnetic-hydraulic delay operation.

Frequently Asked Questions (FAQ)

Q: Can IUG2-28780-1 be used as a direct replacement for IUG6-1-61-20.0-C-01?

A: Yes. Both parts are parametrically equivalent across all critical specifications: current rating, voltage ratings, pole configuration, mounting type, and actuator type. They are functionally interchangeable for circuit protection applications.

Q: Are there any differences in mechanical fit or panel mounting between these parts?

A: Both parts are specified as panel mount with lever actuation. No mechanical differences are indicated in the provided specifications. Physical verification is recommended during integration to confirm mounting hole alignment and clearance in your specific panel configuration.

Q: What is the significance of the UL1077 approval on the IUG2-28780-1?

A: UL1077 is a safety standard for supplementary protectors. This certification on the IUG2-28780-1 may be required for certain applications or regulatory jurisdictions. Confirm whether your application requires this specific certification.

Q: Are both parts RoHS compliant?

A: Yes. Both the IUG6-1-61-20.0-C-01 and IUG2-28780-1 are RoHS compliant with identical moisture sensitivity levels (MSL 1, Unlimited).

Q: What is the difference between the base product numbers IUG6 and IUG2?

A: The base product numbers indicate different part number series within the Sensata-Airpax IUG family. Both series produce functionally equivalent magnetic-hydraulic delay circuit breakers. The difference is in the part numbering scheme, not in electrical or mechanical performance for this specific 50A, 250V AC, 80V DC, single-pole configuration.

Q: Can I mix these parts in the same application or system?

A: Yes, provided your application does not require all components to share identical part numbers for traceability or documentation purposes. Both parts meet the same electrical and mechanical specifications.
