IUG1-1REC4-62-.500-C-21 Equivalent & Substitute Parts

Part Overview

The IUG1-1REC4-62-.500-C-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 AC and DC applications. The part maintains Active product status with 979 units in current inventory stock.

Substitute parts become necessary when the primary part number reaches end-of-life status, inventory depletion, or when alternative series configurations better suit specific application requirements while maintaining identical electrical and mechanical performance parameters.

Key Parameters

Substitute Part Grouping Explanation

All substitute parts listed maintain identical electrical specifications: 10A current rating, 250V AC and 80V DC voltage ratings, magnetic hydraulic delay protection, single-pole configuration, and lever actuation. Substitution eligibility is determined by matching these core parameters across all candidates.

The substitute parts represent different series designations within the Sensata-Airpax product family (IEG1, IEG6, IEL1, and IULK1 base series). Each substitute maintains the same functional performance and mechanical interface requirements as the primary part. Series variation does not affect electrical compatibility or application suitability when all specified parameters align.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts carry Active product status and RoHS Compliant certification. Selection among equivalent options should prioritize inventory availability and application-specific approval requirements.

IEG1-1-62F-10.0-01-V and IEG6-1-72-10.0-01-V include CSA, TUV, and UL1077 approvals, providing enhanced certification coverage for regulated applications. IEL1-1-62-10.0-01-V offers the highest current inventory level at 1176 units. IULK1-1-66-15.0-01 maintains the closest series alignment to the primary IUG designation while delivering equivalent electrical performance.

All parts comply with RoHS requirements and carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating no special storage or handling constraints.

Frequently Asked Questions (FAQ)

Q: Can IEG series breakers replace IUG series breakers in existing applications? A: Yes. Both series share identical electrical ratings (10A, 250V AC, 80V DC), breaker type (magnetic hydraulic delay), mounting configuration (panel mount), and actuator design (lever). Series designation reflects internal design evolution within the Sensata-Airpax product family but does not affect functional compatibility.

Q: What determines if a part is a true substitute? A: Substitution eligibility requires matching current rating, AC and DC voltage ratings, breaker type, mounting type, actuator type, and pole count. All listed parts meet these criteria. Packaging format (Bulk vs. standard) does not affect electrical or mechanical compatibility.

Q: Are there approval differences between substitute options? A: IEG series parts (IEG1-1-62F-10.0-01-V and IEG6-1-72-10.0-01-V) carry CSA, TUV, and UL1077 certifications. IEL and IUL series parts carry standard RoHS compliance. Application requirements may dictate preference for enhanced certification coverage.

Q: Does inventory level affect substitution validity? A: No. Inventory quantity does not determine substitution eligibility. All listed parts maintain Active status and current manufacturing support. Inventory levels reflect current stock availability and should inform procurement timing decisions only.

Q: Can these parts be used interchangeably in the same panel mount location? A: Yes. All substitute parts maintain identical panel mount mechanical interfaces, lever actuation, and single-pole configuration. Physical installation and electrical connection requirements remain unchanged across all equivalent options.
