Equivalent & Substitute Parts for IUG1-1-62-20.0-21

Part Overview

The IUG1-1-62-20.0-21 is a single-pole circuit breaker with magnetic hydraulic delay protection, rated for 10A at 250V AC and 80V DC. Manufactured by Sensata-Airpax, this lever-actuated panel mount breaker is designed for overcurrent protection in industrial and commercial applications. The part is currently active in production with 815 units in stock. Substitute parts become necessary when the original series is unavailable, when alternative packaging formats are required, or when equivalent performance specifications from alternative series within the same manufacturer portfolio can fulfill application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IUG1-1-62-20.0-21 is determined by strict equivalence across the following critical parameters:

• Breaker Type: Magnetic (Hydraulic Delay)
• Current Rating: 10A
• Voltage Rating - AC: 250V
• Voltage Rating - DC: 80V
• Mounting Type: Panel Mount
• Actuator Type: Lever
• Number of Poles: 1
• RoHS Compliance: Required

All five substitute parts listed below meet these criteria across different series designations (IEG1, IEG6, IEL1, and IULK1). Substitution is valid based on functional and electrical equivalence. Series differences reflect manufacturing lineups within the Sensata-Airpax portfolio and do not affect performance in applications requiring these specifications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are manufactured by Sensata-Airpax and maintain active product status. Selection among the five equivalent options should be based on:

Availability and Lead Time: IEL1-1-62-10.0-01-V offers the highest inventory level at 1176 units, followed by IEG1-1-62F-10.0-01-V at 1097 units. IULK1-1-66-15.0-01 has the lowest inventory at 738 units.

Certification Coverage: IEG1-1-62F-10.0-01-V and IEG6-1-72-10.0-01-V carry explicit approval agency certifications (CSA, TUV, UL1077), providing additional compliance documentation for regulated applications. IEL1 and IULK1 series parts do not list these certifications in the provided data.

Packaging Format: The original IUG1-1-62-20.0-21 does not specify packaging format. All substitute parts are supplied in bulk packaging, which may require adjustment to procurement and storage procedures.

RoHS Compliance: All parts maintain RoHS compliance and MSL rating of 1 (Unlimited), ensuring compatibility with modern manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can IEG1-1-62F-10.0-01-V be used as a direct replacement for IUG1-1-62-20.0-21?

A: Yes. Both parts share identical electrical specifications (10A, 250V AC, 80V DC), breaker type (Magnetic Hydraulic Delay), mounting configuration (Panel Mount, Lever Actuated, Single Pole), and RoHS compliance status. The difference in series designation reflects manufacturing portfolio organization and does not affect functional performance.

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

A: Both IEG and IEL series parts meet the electrical and mechanical requirements for substitution. IEG series parts (IEG1-1-62F-10.0-01-V and IEG6-1-72-10.0-01-V) include documented approval agency certifications (CSA, TUV, UL1077). IEL series parts (IEL1-1-51-10.0-01-V and IEL1-1-62-10.0-01-V) do not list these certifications in the provided specifications. Selection depends on whether additional certification documentation is required for the application.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: All substitute parts share identical mounting type (Panel Mount), actuator type (Lever), and pole configuration (Single Pole). No mechanical redesign or panel modification is required for substitution.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Bulk versus unspecified) does not affect electrical performance or functional characteristics. Bulk packaging may impact procurement quantities, storage requirements, and handling procedures but does not alter the component's operational specifications.

Q: Which substitute part should be selected for maximum availability?

A: IEL1-1-62-10.0-01-V provides the highest inventory level at 1176 units in stock, followed by IEG1-1-62F-10.0-01-V at 1097 units.

Q: Are all substitute parts RoHS compliant?

A: Yes. All five substitute parts maintain RoHS compliance and MSL rating of 1 (Unlimited), consistent with the original IUG1-1-62-20.0-21 specification.
