Parametric Equivalents (Diodes Incorporated): Parts 1N4936-T and 1N4936G-T maintain identical electrical specifications to the PR1004-T, including fast recovery characteristics (≤500 ns) and reverse recovery time of 200 ns. These parts differ only in packaging format (Cut Tape vs. Tape & Reel).

Manufacturer Recommended Equivalents: Parts from Vishay General Semiconductor, Micro Commercial Co, and Rectron USA meet the core voltage, current, and package requirements. These parts operate at standard recovery speeds (>500 ns) and are suitable for general-purpose rectification applications where fast recovery is not a design requirement.

Engineering Selection Recommendations

Parametric Equivalents (Diodes Incorporated): The 1N4936-T and 1N4936G-T are direct parametric equivalents to the PR1004-T. Both maintain fast recovery characteristics (≤500 ns) and identical voltage and current ratings. Selection between these two depends on packaging requirements: 1N4936-T is supplied in Cut Tape format, while 1N4936G-T is supplied in Tape & Reel format. Both are RoHS3 compliant and Active product status.

Manufacturer Recommended Equivalents (Standard Recovery): The 1N4004 series from Vishay General Semiconductor, Micro Commercial Co, and Rectron USA are qualified substitutes for applications where standard recovery speed (>500 ns) is acceptable. These parts meet the same voltage and current specifications and are packaged in DO-41 or DO-204AL configurations. All are RoHS3 compliant and Active product status.

Extended Temperature Range Option: The 1N4004G (Rectron USA) and 1N4004GP series (Vishay) offer extended operating temperature ranges up to 175°C, compared to the PR1004-T maximum of 150°C. The 1N4004G includes AEC-Q101 automotive qualification.

High Inventory Availability: The 1N4004GP-E3/54 (Vishay) offers the highest inventory level (40,609 pcs) among all substitutes, followed by 1N4004E-E3/53 (18,891 pcs) and 1N4004G (10,300 pcs).

Frequently Asked Questions (FAQ)

Q: Can I substitute a 1N4004 series diode for the PR1004-T?

A: Yes. The 1N4004 series maintains the same 400 V reverse voltage rating and 1 A average rectified current. The primary difference is recovery speed: the PR1004-T is fast recovery (150 ns), while 1N4004 parts are standard recovery (>500 ns). For general-purpose rectification applications, this difference is not critical. For high-frequency switching applications, the fast recovery characteristic of the PR1004-T or 1N4936 series is required.

Q: What is the difference between 1N4936-T and 1N4936G-T?

A: Both parts are electrically identical with 400 V, 1 A ratings and fast recovery characteristics. The difference is packaging: 1N4936-T is supplied in Cut Tape (CT) format, while 1N4936G-T is supplied in Tape & Reel (TR) format. Selection depends on assembly equipment and production volume requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance status, matching the PR1004-T specification.

Q: Can I use a 1N4004GP-E3/54 in place of PR1004-T in a high-frequency circuit?

A: The 1N4004GP-E3/54 has a standard recovery time of 2 µs, compared to the PR1004-T fast recovery time of 150 ns. In high-frequency switching applications, the slower recovery time may introduce additional switching losses and heat generation. For circuits operating above 100 kHz, the fast recovery 1N4936 series is the appropriate substitute.

Q: What is the temperature operating range difference?

A: The PR1004-T operates from -65°C to 150°C. Most 1N4004 variants operate from -55°C to 150°C, with extended-range options (1N4004G, 1N4004GP series) rated to 175°C. Selection depends on application thermal requirements.

Q: Are there any REACH or ECCN restrictions on these parts?

A: All listed parts carry ECCN classification EAR99 and are either REACH Unaffected or have REACH information available upon request. No export restrictions apply to standard commercial applications.

Q: What packaging options are available?

A: All substitute parts are available in through-hole axial packages: DO-41 or DO-204AL (functionally equivalent). Packaging format options include Cut Tape (CT), Tape & Reel (TR), and Tape & Box (TB), depending on the specific part number and manufacturer.
