IUG66-0-SW-50.0-AQ-01 Equivalent & Substitute Parts

Part Overview

The IUG66-0-SW-50.0-AQ-01 is a panel-mounted circuit breaker with magnetic hydraulic delay protection, rated for 30A at 250V AC and 80V DC. Manufactured by Sensata-Airpax, this component is classified as Active product status with full RoHS compliance. Substitute parts become necessary due to inventory constraints, manufacturing discontinuation, or specific application requirements while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for a part to qualify as a substitute:

• Current Rating: 30A
• Voltage Rating AC: 250V
• Voltage Rating DC: 80V
• Breaker Type: Magnetic (Hydraulic Delay)
• Mounting Type: Panel Mount
• Actuator Type: Lever
• Number of Poles: 2
• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed below meet these criteria and are manufactured by Sensata-Airpax or Sensata Technologies – Airpax. Variations in base product numbers (IUG11, IUG68, IEG66, IEGH66) reflect different series designations within the manufacturer's product line but do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and full RoHS compliance. Selection should be based on inventory availability and application-specific certification requirements:

IUG11-1-65F-15.0-01 and IUG68-1REC2-25882-1 are IUG series variants with equivalent electrical specifications. IUG68-1REC2-25882-1 carries UL1077 approval.

IEG66-1REC4-62F-30.0-01-V and IEGH66-1-72-30.0-01-V are IEG series alternatives with expanded regulatory approvals including CSA, TUV, and UL1077 certifications. These parts are suitable for applications requiring enhanced regulatory compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can IUG11-1-65F-15.0-01 be used as a direct replacement for IUG66-0-SW-50.0-AQ-01?

A: Yes. Both parts share identical electrical ratings (30A, 250V AC, 80V DC), breaker type (Magnetic Hydraulic Delay), mounting configuration (Panel Mount), and actuator design (Lever). RoHS compliance and MSL ratings are equivalent.

Q: What is the difference between IUG series and IEG series substitutes?

A: IUG and IEG series parts are functionally equivalent across all provided electrical and mechanical parameters. The IEG series variants (IEG66-1REC4-62F-30.0-01-V and IEGH66-1-72-30.0-01-V) include additional regulatory approvals (CSA, TUV, UL1077) compared to the base IUG series.

Q: Are packaging differences significant for substitution?

A: Packaging format (Bulk vs. standard) does not affect electrical or mechanical compatibility. Selection should be based on procurement and inventory management requirements.

Q: Do all substitute parts carry the same certifications?

A: IUG68-1REC2-25882-1 carries UL1077 approval. IEG66-1REC4-62F-30.0-01-V and IEGH66-1-72-30.0-01-V carry CSA, TUV, and UL1077 approvals. Applications requiring specific regulatory certifications should reference the approval agency field for each part.

Q: Is there a preferred substitute based on inventory levels?

A: IUG66-0-SW-50.0-AQ-01 has the highest inventory (1069 Pcs). Among substitutes, IUG11-1-65F-15.0-01 offers the next highest availability (966 Pcs). Selection should align with supply chain and delivery requirements.
