Engineering Selection Recommendations

Direct Package Replacement (DO-15 / DO-204AC Axial):

GPP20J-E3/73 and FR205T/R are direct mechanical and electrical replacements for the PR2005G-T. Both maintain the DO-15 package configuration, matching pinout and board layout requirements. GPP20J-E3/73 is manufactured by Vishay and carries active product status with full availability. FR205T/R, manufactured by EIC Semiconductor, is also active and provides parametric equivalence with identical forward voltage and recovery time specifications.

Alternative Package Configurations (SOD-57 and DO-41 Axial):

BYW36-TR, BYW54-TR, and MUR260RLG provide functional equivalence with different axial package geometries. These parts require mechanical board layout modification but maintain electrical compatibility. BYW36-TR and BYW54-TR employ avalanche diode technology and are manufactured by Vishay. MUR260RLG is manufactured by onsemi and features the fastest reverse recovery time (75 ns) among all substitutes.

Product Status Consideration:

All substitute parts carry active product status, ensuring long-term availability and supply chain stability. The PR2005G-T's obsolete classification necessitates transition to one of these active alternatives for new designs and ongoing production support.

Compliance and Certification:

All substitute parts are RoHS3 compliant and REACH unaffected, matching the regulatory status of the original part. Moisture sensitivity levels are equivalent (MSL 1 - Unlimited) across all options.

Frequently Asked Questions (FAQ)

Q: Can BYW36-TR and BYW54-TR be used as direct replacements for PR2005G-T?

A: BYW36-TR and BYW54-TR are electrically equivalent but use SOD-57 package geometry instead of DO-15. Both are axial through-hole packages, but physical dimensions differ. Board layout modification is required. Both parts meet the 600 V / 2 A electrical specifications.

Q: What is the difference between BYW36-TR and BYW54-TR?

A: Both parts are 600 V / 2 A avalanche diodes in SOD-57 packages. BYW36-TR features fast recovery (200 ns) with forward voltage of 1.1 V @ 1 A. BYW54-TR features standard recovery (4 µs) with lower forward voltage of 1 V @ 1 A. Selection depends on circuit speed requirements.

Q: Is GPP20J-E3/73 a direct replacement for PR2005G-T?

A: Yes. GPP20J-E3/73 is a direct replacement. Both use DO-15 package configuration with identical pinout and board layout compatibility. Electrical specifications are equivalent: 600 V / 2 A with standard diode technology. GPP20J-E3/73 carries active product status.

Q: Why does MUR260RLG have a faster recovery time than PR2005G-T?

A: MUR260RLG features a reverse recovery time of 75 ns compared to PR2005G-T's 250 ns. This faster recovery is an inherent characteristic of the MUR260 design. Both parts meet the fast recovery classification (≤500 ns). The faster recovery may reduce switching losses in high-frequency applications.

Q: Can FR205T/R be used as a substitute?

A: Yes. FR205T/R is a parametric equivalent manufactured by EIC Semiconductor. It maintains DO-15 package compatibility, 600 V / 2 A ratings, and identical forward voltage (1.3 V @ 2 A) and recovery time (250 ns) specifications. Reverse leakage is slightly higher at 10 µA versus 5 µA.

Q: What are the temperature range differences among substitutes?

A: PR2005G-T operates -65°C to 150°C. BYW36-TR and BYW54-TR extend to 175°C. MUR260RLG also reaches 175°C. GPP20J-E3/73 and FR205T/R match the original -65°C to 150°C range. Selection depends on application thermal requirements.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All substitute parts listed are RoHS3 compliant, matching the regulatory status of PR2005G-T. All parts are REACH unaffected.

Q: Which substitute has the lowest forward voltage drop?

A: BYW54-TR exhibits the lowest forward voltage at 1 V @ 1 A. However, this measurement is taken at 1 A, not 2 A. At 2 A operation, GPP20J-E3/73 and MUR260RLG show 1.1 V and 1.35 V respectively. Direct voltage comparison requires matching test conditions.
