IAG6-1-51-25.0-Q-21 Equivalent & Substitute Parts

Part Overview

The IAG6-1-51-25.0-Q-21 is a single-pole circuit breaker with magnetic-hydraulic delay protection, rated for 25A at 250V AC and 80V DC. It features lever actuation and panel mount configuration. The part is active in production status and RoHS compliant with MSL 1 rating. Equivalent substitute parts are necessary when the primary part is unavailable or when alternative series options are required to meet procurement or inventory requirements while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the IAG6-1-51-25.0-Q-21 is determined by strict equivalence across the following parameters: current rating (25A), AC voltage rating (250V), DC voltage rating (80V), breaker type (magnetic with hydraulic delay), actuator type (lever), pole configuration (single pole), and mounting method (panel mount). All substitute parts must maintain identical electrical performance characteristics and mechanical interface compatibility. The identified substitutes—IEG6-1-72-25.0-01-V and IELK1-1-72-25.0-01-V—meet these criteria across all specified parameters, differing only in series designation and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status with full RoHS compliance and identical MSL ratings. The IEG6-1-72-25.0-01-V carries CSA, TUV, and UL1077 certifications, providing the broadest regulatory approval scope. The IELK1-1-72-25.0-01-V holds UL1077 certification. Selection between substitutes should be based on specific regulatory requirements for the end application and packaging preferences, as all parts are electrically and mechanically equivalent.

Frequently Asked Questions (FAQ)

Q: Can IEG6-1-72-25.0-01-V and IELK1-1-72-25.0-01-V be used interchangeably with IAG6-1-51-25.0-Q-21?

A: Yes. All three parts share identical electrical ratings (25A, 250V AC, 80V DC), breaker type (magnetic-hydraulic delay), actuator configuration (lever), pole count (single), and mounting method (panel mount). They are parametric equivalents suitable for direct substitution in circuit protection applications.

Q: What are the differences between the substitute parts?

A: The primary differences are series designation (IEG versus IELK) and regulatory certifications. IEG6-1-72-25.0-01-V includes CSA and TUV approvals in addition to UL1077, while IELK1-1-72-25.0-01-V carries UL1077 certification only. Both are supplied in bulk packaging.

Q: Are there any mechanical interface differences?

A: No. All parts feature identical panel mount configuration and lever actuation, ensuring mechanical compatibility in existing installations.

Q: What is the significance of the MSL 1 rating?

A: MSL 1 indicates unlimited shelf life with no moisture sensitivity restrictions, allowing standard storage and handling without special environmental controls.

Q: Which substitute should be selected for international applications?

A: IEG6-1-72-25.0-01-V is recommended for international applications due to its CSA and TUV certifications in addition to UL1077, providing broader regulatory acceptance across North American and European markets.
