IUGZX1-1-62-.500-C-94 Equivalent & Substitute Parts

Part Overview

The IUGZX1-1-62-.500-C-94 is a magnetic hydraulic delay circuit breaker manufactured by Sensata-Airpax, rated for 7.5A at 250V AC and 80V DC with rocker panel mount actuation and 2-pole configuration. This part is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. Active equivalent models from both Sensata-Airpax and Carling Technologies are available with identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts are qualified based on strict parametric equivalence across all critical electrical and mechanical specifications. The following parameters determine substitution eligibility:

Current Rating: 7.5A (exact match required)
Voltage Rating AC: 250V (exact match required)
Voltage Rating DC: 80V (exact match required)
Breaker Type: Magnetic (Hydraulic Delay) (exact match required)
Mounting Type: Panel Mount (exact match required)
Actuator Type: Rocker (exact match required)
Number of Poles: 2 (exact match required)

All substitute parts listed meet these criteria. Sensata-Airpax substitutes represent direct series evolution from the obsolete IUG series to the active IEG series. Carling Technologies substitutes provide cross-manufacturer equivalence with identical electrical performance and mechanical interface compatibility.

Engineering Selection Recommendations

For applications requiring the IUGZX1-1-62-.500-C-94, selection between available substitutes depends on product status and regulatory compliance requirements.

Sensata-Airpax IEG Series (IEGZX11-1-62-7.50-G-G3-V and IEGZX11-1-62F-7.50-G-G3-V): These parts represent the direct active equivalent from the original manufacturer. Both are RoHS Compliant and carry CSA, TUV, and UL1077 approvals. The IEG series maintains design continuity with the obsolete IUG series while offering active production status and current manufacturer support.

Carling Technologies M Series (MA2 variants): All Carling Technologies substitutes are ROHS3 Compliant and REACH Unaffected, with active production status. Approval agencies vary by specific part number but include combinations of CCC, CSA, TUV, UL, VDE, and UL1077. These parts provide cross-manufacturer equivalence with identical electrical and mechanical specifications.

Selection between manufacturers should be based on existing supply chain relationships, approval agency requirements for the target application, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can any of these substitute parts directly replace the IUGZX1-1-62-.500-C-94?

A: Yes. All listed substitute parts meet identical electrical specifications (7.5A, 250V AC, 80V DC) and mechanical requirements (2-pole, rocker actuator, panel mount, magnetic hydraulic delay operation). Direct substitution is supported from an electrical and mechanical standpoint.

Q: What is the difference between the two Sensata-Airpax IEG series parts?

A: Both IEGZX11-1-62-7.50-G-G3-V and IEGZX11-1-62F-7.50-G-G3-V are parametrically equivalent. The designation difference reflects internal configuration variations within the IEG series, but both deliver identical electrical performance and mechanical interface compatibility.

Q: Why are there multiple Carling Technologies part numbers if they are all equivalent?

A: The Carling Technologies M series uses a modular part numbering system where different alphanumeric codes represent configuration options (such as terminal types, contact materials, or internal specifications) that do not affect the core electrical or mechanical parameters relevant to this substitution. All listed variants maintain the required 7.5A, 250V AC, 80V DC specifications and panel mount rocker configuration.

Q: Are there compliance differences between Sensata-Airpax and Carling Technologies options?

A: Both manufacturers' parts are RoHS compliant. Sensata-Airpax IEG series carries CSA, TUV, and UL1077 approvals. Carling Technologies M series variants carry different combinations of CCC, CSA, TUV, UL, VDE, and UL1077 approvals depending on specific part number. Verify that the selected part's approval agencies align with application requirements.

Q: Is the obsolete status of the original part a concern for long-term availability?

A: The original IUGZX1-1-62-.500-C-94 is obsolete, but all substitute parts listed are in active production. Sensata-Airpax IEG series and Carling Technologies M series parts maintain current manufacturing status with established supply chains.
