Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IUGH1111-1-42F-5.00-21 are qualified based on the following criteria:

Electrical Equivalence: All substitute parts maintain identical current rating (20A), AC voltage rating (250V), and DC voltage rating (80V).

Mechanical Compatibility: All substitutes feature panel mount configuration with lever actuator and 2-pole design.

Functional Equivalence: All substitutes employ magnetic hydraulic delay protection mechanism.

Compliance: All substitutes maintain RoHS compliance and MSL 1 rating.

The substitute parts represent different series variants (IEL, IEG, IEGS, IUG) from Sensata-Airpax, each meeting the electrical and mechanical parameters required for direct substitution in applications designed for the IUGH1111-1-42F-5.00-21.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are qualified for direct replacement based on electrical and mechanical parameter equivalence. Selection among substitutes may be influenced by the following factors:

Regulatory Compliance: Parts with UL1077 certification (IELHK11-1-72-20.0-01-V, IEG11-1-62F-20.0-A-00, IEGH11-1-72-20.0-01-V, IEGS66-1-61-20.0-A-41-V) provide additional approval agency documentation. Parts with CSA and TUV certifications (IEG11-1-62F-20.0-A-00, IEGH11-1-72-20.0-01-V, IEGS66-1-61-20.0-A-41-V) meet broader international standards.

Product Status: All substitute parts maintain Active product status, ensuring continued availability and support.

Series Consistency: IUG series substitutes (IUG66-1-61-30.0-C-01, IUG66-1-61-10.0-CQ-01) maintain the same series as the primary part. IEL and IEG series substitutes represent alternative product lines with equivalent electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can IELHK11-1-72-20.0-01-V replace IUGH1111-1-42F-5.00-21 in existing installations?

A: Yes. Both parts share identical electrical ratings (20A, 250V AC, 80V DC), mounting configuration (panel mount), actuator type (lever), pole count (2), and breaker mechanism (magnetic hydraulic delay). The IELHK11-1-72-20.0-01-V includes UL1077 certification.

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

A: Both series meet the electrical and mechanical requirements for substitution. IEG series parts (IEG11-1-62F-20.0-A-00, IEGH11-1-72-20.0-01-V, IEGS66-1-61-20.0-A-41-V) include additional approval agencies (CSA, TUV, UL1077), while IUG series parts maintain the same series designation as the primary part.

Q: Are all substitutes RoHS compliant?

A: Yes. All listed substitute parts are RoHS compliant with MSL 1 (Unlimited) rating, matching the primary part specification.

Q: Does packaging affect substitution eligibility?

A: No. Packaging format (Bulk or standard) does not affect electrical or mechanical compatibility. All substitutes are functionally equivalent regardless of packaging configuration.

Q: Which substitute has the broadest regulatory approval?

A: IEGH11-1-72-20.0-01-V and IEGS66-1-61-20.0-A-41-V both carry CSA, TUV, and UL1077 certifications, providing the most comprehensive approval agency documentation among the listed substitutes.
