PR2007G-T Equivalent & Substitute Parts

Part Overview

The PR2007G-T is a general-purpose rectifier diode manufactured by Diodes Incorporated, rated for 1000 V DC reverse voltage and 2 A average rectified current in a DO-15 through-hole package. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing design requirements and production continuity. Substitute parts must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating package and mounting variations.

Substitute Part Grouping Explanation

Substitution of the PR2007G-T is determined by the following critical parameters:

Mandatory Electrical Compatibility:

Voltage - DC Reverse (Vr) (Max): Must equal or exceed 1000 V
Current - Average Rectified (Io): Must equal or exceed 2 A
Mounting Type: Through Hole required
RoHS Status: ROHS3 Compliant required

Package Compatibility Considerations:

DO-15 package (primary): Direct mechanical and electrical substitution
DO-41 Axial package: Functionally equivalent with different form factor; requires PCB layout modification
SOD-57 package: Functionally equivalent with different form factor; requires PCB layout modification

Secondary Parameters Influencing Selection:

Reverse Recovery Time (trr): Lower values indicate faster switching performance
Forward Voltage (Vf): Lower values reduce power dissipation
Product Status: Active status ensures ongoing availability and supply chain continuity

Substitute parts are grouped into two categories: Package-Compatible Substitutes (DO-15 package) and Functionally Equivalent Substitutes (alternative packages with matching electrical ratings).

Engineering Selection Recommendations

Primary Substitute - Package Compatible (DO-15):

HER208G-TP is the recommended direct substitute for the PR2007G-T. Both components share the DO-15 package, enabling pin-for-pin replacement without PCB layout modification. HER208G-TP maintains 1000 V reverse voltage rating and 2 A current capacity. The component is manufactured by Micro Commercial Co with active product status, ensuring supply chain continuity. RoHS3 compliance and unlimited moisture sensitivity level (MSL 1) match the original specification. Reverse recovery time of 75 ns provides improved switching performance compared to the PR2007G-T (500 ns). Forward voltage of 1.7 V @ 2 A represents a 0.4 V increase, resulting in marginally higher power dissipation in thermal-sensitive applications.

Secondary Substitute - Package Compatible (DO-15):

STTH208 manufactured by STMicroelectronics provides DO-15 package compatibility. This component operates at 800 V maximum reverse voltage, which is 200 V below the PR2007G-T specification. STTH208 is suitable only for applications where the circuit design margin permits operation at reduced voltage ratings. The component offers superior reverse recovery time (75 ns) and active product status. Forward voltage of 1.65 V @ 2 A falls between HER208G-TP and the original PR2007G-T.

Functionally Equivalent Substitutes - Alternative Packages:

MUR2100EG and MUR2100ERLG (onsemi SWITCHMODE™ series) provide functional equivalence with DO-41 Axial package configuration. Both variants maintain 1000 V reverse voltage and 2 A current ratings with fast recovery characteristics (100 ns trr). MUR2100ERLG offers significantly higher inventory availability (55100 pcs) compared to MUR2100EG (8945 pcs). Operating temperature range extends to 175 °C maximum, exceeding the PR2007G-T specification. Forward voltage of 2.2 V @ 2 A represents the highest among all substitutes, requiring thermal analysis for power-dissipation-critical applications. PCB layout modification is required due to different package form factor.

BYW56-TR (Vishay General Semiconductor) provides functional equivalence in SOD-57 package with 1000 V reverse voltage and 2 A current rating. This component utilizes avalanche technology with standard recovery characteristics (4 µs trr), making it suitable for applications not requiring fast switching performance. Forward voltage of 1 V @ 1 A (measured at 1 A, not 2 A) indicates superior low-current performance. Operating temperature range of -55 to 175 °C and highest inventory availability (32117 pcs) support production continuity. PCB layout modification is required.

Compliance and Regulatory Status:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original PR2007G-T regulatory requirements. ECCN classification (EAR99) and HTSUS code (8541.10.0080) remain consistent across all options.

Frequently Asked Questions (FAQ)

Q: Can HER208G-TP be used as a direct replacement for PR2007G-T without PCB modification?

A: Yes. HER208G-TP shares the DO-15 package with identical pin configuration and through-hole mounting. No PCB layout changes are required. Both components are axial-lead diodes with equivalent mechanical dimensions.

Q: What is the significance of the 200 V voltage difference between PR2007G-T (1000 V) and STTH208 (800 V)?

A: The voltage rating represents the maximum reverse voltage the diode can withstand without breakdown. STTH208 is suitable only for circuits designed for 800 V operation or lower. If the original design requires 1000 V capability, STTH208 is not appropriate.

Q: Why do MUR2100EG and MUR2100ERLG have higher forward voltage (2.2 V) compared to HER208G-TP (1.7 V)?

A: Forward voltage varies with diode technology, doping profile, and junction design. Higher forward voltage results in greater power dissipation at the same current level. Thermal analysis is required for applications where power dissipation is a limiting factor.

Q: Can BYW56-TR be used in high-frequency switching applications?

A: BYW56-TR has standard recovery characteristics (4 µs trr) rather than fast recovery. This makes it unsuitable for high-frequency switching applications where fast recovery time (≤ 500 ns) is required. Use BYW56-TR only in applications tolerating slower switching speeds.

Q: What is the difference between MUR2100EG and MUR2100ERLG?

A: Both parts are electrically identical with the same electrical specifications. The primary difference is packaging: MUR2100EG is supplied in bulk, while MUR2100ERLG is supplied in cut tape (CT). MUR2100ERLG offers significantly higher inventory availability (55100 pcs vs. 8945 pcs).

Q: Does operating temperature range affect substitution suitability?

A: Operating temperature range defines the thermal environment in which the component functions reliably. PR2007G-T operates from -65 to 150 °C. Substitutes with extended ranges (e.g., -65 to 175 °C) provide additional thermal margin but do not restrict use in applications within the original temperature range.

Q: Why is reverse recovery time important for diode selection?

A: Reverse recovery time (trr) determines how quickly the diode transitions from conducting to blocking state. Shorter trr reduces switching losses and electromagnetic interference in high-frequency circuits. Fast recovery diodes (≤ 500 ns) are required for switching power supplies and high-frequency rectification.

Q: Can substitute parts with different packages be used interchangeably?

A: No. Different packages (DO-15, DO-41, SOD-57) have different physical dimensions and pin spacing. PCB layout modification is required when changing packages. Mechanical fit and electrical connectivity must be verified before implementation.

Q: What does "Active" product status mean for substitute parts?

A: Active status indicates the manufacturer continues production and supports the component through its full lifecycle. This ensures ongoing availability, technical support, and supply chain continuity. Obsolete status (PR2007G-T) indicates the manufacturer has discontinued production.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance, matching the original PR2007G-T specification. This ensures compatibility with environmental and regulatory requirements across global markets.
