PR3004-T Equivalent & Substitute Parts

Part Overview

The PR3004-T is a general-purpose rectifier diode manufactured by Diodes Incorporated, rated for 400 V DC reverse voltage and 3 A average rectified current in a DO-201AD axial through-hole package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The PR3004-T features fast recovery characteristics with a reverse recovery time of 150 ns, suitable for applications requiring rapid switching performance in rectification circuits.

Substitute Part Grouping Explanation

Substitute parts for the PR3004-T are selected based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Electrical Parameters:

Voltage - DC Reverse (Vr) (Max): 400 V (exact match required)
Current - Average Rectified (Io): 3 A (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: DO-201AD, Axial (exact match required)

Secondary Considerations:

Forward voltage (Vf) within acceptable operating range
Recovery speed classification (fast or standard recovery acceptable)
Reverse leakage current within specified limits
Operating temperature range compatibility
RoHS compliance status

Substitute parts are grouped into two categories: Active Status Parts (suitable for new designs and ongoing production) and Not For New Designs Parts (available for legacy system maintenance). Parts with obsolete or not-for-new-designs status are included for reference but should be evaluated against active alternatives.

Engineering Selection Recommendations

For Active Production and New Designs:

The following parts are recommended as primary substitutes for the PR3004-T due to active product status and full compliance certifications:

1N5404-E3/54 (Vishay): Active status, ROHS3 compliant, standard recovery characteristics, electrical parameters match PR3004-T specifications. Suitable for applications where fast recovery is not critical.
1N5404-G (Comchip Technology): Active status, ROHS3 compliant, largest inventory availability (208,868 pcs), standard recovery characteristics. Forward voltage is lower (950 mV) than PR3004-T, reducing power dissipation in rectification circuits.
31GF4-E3/54 (Vishay): Active status, ROHS3 compliant, fast recovery characteristics (30 ns trr) matching the speed classification of PR3004-T. Suitable for high-frequency switching applications.
BY252P-E3/54 (Vishay): Active status, ROHS3 compliant, standard recovery characteristics, forward voltage (1.1 V) closely matches PR3004-T (1.2 V).
P300G-E3/54 (Vishay): Active status, ROHS3 compliant, standard recovery characteristics, forward voltage and reverse leakage match PR3004-T specifications.

For Legacy System Maintenance:

MR854G and MR854RLG (onsemi): Active status, ROHS3 compliant, fast recovery characteristics. These parts are suitable for replacement in existing systems where fast recovery performance is required. Higher inventory availability (MR854RLG: 29,000 pcs).
1N5404G and 1N5404RLG (onsemi): Not for new designs but available for legacy system support. Both parts maintain 400 V / 3 A ratings and ROHS3 compliance.

Compliance Considerations:

All recommended substitute parts are ROHS3 compliant and carry EAR99 ECCN classification, matching the regulatory status of the PR3004-T. Parts are available in standard packaging formats (Cut Tape, Tape & Reel, or Bulk) suitable for production environments.

Frequently Asked Questions (FAQ)

Q: Can I use a standard recovery diode as a substitute for the PR3004-T fast recovery diode?

A: Yes, standard recovery diodes (trr > 500 ns) are electrically compatible substitutes for fast recovery diodes in most rectification applications. Standard recovery diodes will function correctly in circuits designed for the PR3004-T. However, in high-frequency switching applications or circuits with tight timing requirements, fast recovery characteristics may be preferred to minimize switching losses and reverse recovery current spikes.

Q: What is the difference between DO-201AD and DO-27 packages?

A: Both designations refer to the same axial through-hole package format. DO-201AD is the formal JEDEC designation, while DO-27 is an alternative industry designation. Parts specified with either designation are mechanically and electrically interchangeable in through-hole PCB applications.

Q: Are all substitute parts ROHS3 compliant?

A: All recommended substitute parts listed in this document are ROHS3 compliant, matching the compliance status of the PR3004-T. This ensures compatibility with modern manufacturing and environmental regulations.

Q: Which substitute part has the lowest forward voltage drop?

A: The 1N5404-G (Comchip Technology) has the lowest forward voltage at 950 mV @ 3 A, compared to the PR3004-T specification of 1.2 V @ 3 A. This lower forward voltage reduces power dissipation and heat generation in rectification circuits.

Q: Can I use the 1N5418 as a substitute for the PR3004-T?

A: No. The 1N5418 is a surface-mount device in SQ-MELF package format, while the PR3004-T is a through-hole axial component. These parts are not mechanically compatible and require different PCB mounting approaches. The 1N5418 is listed for reference only and is not a suitable substitute for through-hole applications.

Q: What is the operating temperature range difference between substitute parts?

A: The PR3004-T operates from -65°C to 150°C. Most substitute parts maintain this range or exceed it. The 1N5404-G (Comchip) operates to -65°C to 125°C, which is slightly more limited at the upper temperature boundary. The 1N5418 (Microchip) extends to 175°C, providing wider temperature margin for high-temperature applications.

Q: Which substitute part has the highest inventory availability?

A: The 1N5404-G (Comchip Technology) has the highest inventory availability at 208,868 pcs in stock, followed by MR854RLG (onsemi) at 29,000 pcs. These parts are suitable for high-volume production requirements.

Q: Are there differences in reverse leakage current between substitute parts?

A: Yes. The PR3004-T specifies 5 µA @ 400 V reverse leakage. Most substitute parts maintain this specification (1N5404-E3/54, 1N5404-G, BY252P-E3/54, P300G-E3/54). The onsemi parts (1N5404G, 1N5404RLG, MR854G, MR854RLG) specify 10 µA @ 400 V, which is acceptable for most applications. The 31GF4-E3/54 specifies 20 µA @ 400 V, still within acceptable limits for general-purpose rectification.
