IUG66-0-SW-30.0-01 Equivalent & Substitute Parts

Part Overview

The IUG66-0-SW-30.0-01 is a single-pole circuit breaker with magnetic hydraulic delay protection, rated for 5A 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 product maintains Active status with full RoHS compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts may be required due to inventory constraints, supply chain discontinuities, or application-specific design revisions while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitution eligibility for the IUG66-0-SW-30.0-01 is determined by strict equivalence across the following critical parameters:

• Current Rating: 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)
• Actuator Type: Lever (exact match required)
• Mounting Type: Panel Mount (exact match required)
• Number of Poles: 1 (exact match required)

The IELK1-1-72-5.00-01-V meets all substitution criteria as a parametric equivalent, belonging to the IEL series while maintaining identical electrical specifications and mechanical interface requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the IUG66-0-SW-30.0-01 and IELK1-1-72-5.00-01-V are Active products manufactured by Sensata-Airpax with full RoHS compliance and UL1077 approval certification on the substitute part. Selection between these parts should be based on availability and supply chain requirements, as all electrical and mechanical parameters are identical. The IELK1-1-72-5.00-01-V substitute maintains equivalent performance characteristics and regulatory compliance for direct replacement applications.
