Equivalent & Substitute Parts Reference: UPR5/TR7

Part Overview

The UPR5/TR7, manufactured by Microchip Technology, is a general-purpose fast-recovery rectifier diode categorized under Diodes, Rectifiers. It features a maximum DC reverse voltage of 50 V and average rectified current of 2.5 A, with a surface mount DO-216AA package. The device is active and listed as RoHS non-compliant. It is often essential to identify alternative models if compliance, packaging, or supply chain requirements change, while maintaining identical electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution is permissible when all key electrical and mechanical parameters match exactly. For the Diodes, Rectifiers category, the following parameters were considered: Voltage - DC Reverse (Vr) (Max), Current - Average Rectified (Io), Voltage - Forward (Vf) (Max) @ If, speed and reverse recovery time, reverse leakage current, mounting type, package / case, supplier device package, and operating temperature range. Substitute selection excludes any inferences or extrapolations and only uses explicit parameter matches.

Parameter Comparison

Engineering Selection Recommendations

The UPR5E3/TR7 is an appropriate substitute for UPR5/TR7 due to exact matches in all specified electrical and mechanical parameters, category, and package. The substitute part also carries ROHS3 compliance while both share the same product status as active, permitting direct substitution in applications requiring RoHS certification.

Frequently Asked Questions (FAQ)

Q1: What are the key criteria for substituting UPR5/TR7 in the Diodes, Rectifiers category?
A1: Substitute selection requires identical values for voltage, current, forward voltage, speed, reverse recovery time, leakage current, mounting style, and package.

Q2: Can UPR5E3/TR7 be directly replaced for UPR5/TR7 in the same board layout?
A2: Yes. Both diodes utilize the DO-216AA package and supplier device package, making them interchangeable within existing layouts.

Q3: Does the difference in packaging type (Tape & Reel vs. Cut Tape & Digi-Reel®) affect electrical compatibility?
A3: No. Packaging type affects delivery format, not electrical or mechanical compatibility.

Q4: Why would selection preference shift from UPR5/TR7 to UPR5E3/TR7?
A4: The UPR5E3/TR7 provides ROHS3 compliance, which meets environmental regulatory requirements not satisfied by UPR5/TR7.

Q5: Are there temperature or reliability differences between UPR5/TR7 and its substitute?
A5: No differences; both support -55°C to 150°C operating junction temperature.

Q6: Which compliance standards are relevant in selecting a substitute part for UPR5/TR7?
A6: RoHS status and REACH status are specified; UPR5E3/TR7 meets ROHS3 and REACH Unaffected standards.
