104-PR3-2A Equivalent & Substitute Parts Reference

Part Overview

The E-T-A 104-PR3-2A is a thermal circuit breaker rated for 2A at 240 VAC and 48 VDC, featuring a push-to-reset actuator, through-hole mounting, single pole, and a bulk packaging option. This component is active and RoHS3 compliant, with recognized agency approvals including CE, CSA C22.2 No 235, GB 17701, IEC 60934, and UL1077. Alternative models are necessary for scenarios requiring inventory continuity, multi-source strategies, or to address supply chain constraints, provided that substitute parts strictly match all specified functional and compliance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution is based exclusively on precise matching of the following key parameters: manufacturer series, current rating, voltage ratings for AC and DC, breaker type, actuator type, mounting type, number of poles, packaging, approval agency certifications, RoHS status, REACH status, ECCN, HTSUS code, and part status. Only parts that explicitly confirm these criteria are included as substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection of the E-T-A 104-PR-2A as a substitute for the 104-PR3-2A is based on direct parameter equivalency, active part status, and identical RoHS3 compliance and international approval agency certifications. Both parts offer matching electrical ratings, mechanical characteristics, environmental compliance, and agency approvals, strictly according to the provided parameters.

Frequently Asked Questions (FAQ)

Q1: What criteria determine an acceptable substitute for the E-T-A 104-PR3-2A?
A1: Acceptable substitutes must strictly match current rating, voltage ratings, breaker type, actuator type, mounting type, number of poles, packaging, agency approvals, RoHS and REACH status, ECCN, HTSUS, series, and part status.

Q2: Are there differences in form factor or mechanical features between 104-PR3-2A and 104-PR-2A?
A2: No differences are present based on the provided parameters; both parts share the same through hole mounting and bulk packaging.

Q3: How do approval agencies impact substitute selection?
A3: Substitute parts are only included if they list the same approval agencies as the main part number, ensuring compliance with CE, CSA, GB, IEC, and UL standards.

Q4: Can environmental compliance status affect part substitution?
A4: Both components are RoHS3 compliant and REACH unaffected, guaranteeing matched environmental compliance for substitution.

Q5: What packaging information is relevant for substitution?
A5: Both main and substitute parts are specified in bulk packaging, ensuring compatibility in automated assembly or manual production environments.
