Substitute Part Grouping Explanation
Substitute parts for the 1N4004G are classified into two categories based on electrical and mechanical compatibility:
Parametric Equivalents share identical or functionally equivalent electrical specifications (400 V reverse voltage, 1 A average rectified current, 1 V forward voltage drop at 1 A, standard recovery speed, through-hole DO-41 mounting). These parts are direct functional replacements with no circuit redesign required.
Similar Substitutes maintain the same voltage and current ratings and through-hole axial package form factor but may exhibit variations in forward voltage drop, recovery speed, reverse leakage current, or capacitance. These parts are compatible within the same application class but require verification of circuit performance parameters.
Key substitution criteria:
- Voltage - DC Reverse (Vr) (Max): 400 V minimum
- Current - Average Rectified (Io): 1 A minimum
- Mounting Type: Through Hole
- Package / Case: DO-41 or DO-204AL (axial)
- Operating Temperature Range: Must encompass application requirements

Engineering Selection Recommendations
Parametric Equivalents (Direct Replacement):
The 1N4004G-T (Diodes Incorporated) and 1N4004G (Rectron USA) are parametric equivalents with identical electrical specifications to the primary 1N4004G part. Both are Active product status and ROHS3 compliant. The Rectron USA variant includes AEC-Q101 automotive qualification. These parts are suitable for direct substitution without circuit modification.
Standard Recovery Substitutes:
The GP10G-E3/54 (Vishay General Semiconductor, SUPERECTIFIER® series) maintains standard recovery speed characteristics matching the primary part, with forward voltage of 1.1 V at 1 A and operating temperature range of -65°C to 175°C. This part is ROHS3 compliant and Active status, supporting applications with identical thermal and speed requirements.
Fast Recovery Substitutes:
The UF4004-E3/53, UF4004-E3/54 (Vishay General Semiconductor), and UF4004 (Diotec Semiconductor) provide fast recovery characteristics (≤500 ns) compared to the standard recovery speed of the primary part. These substitutes are suitable for applications where reduced reverse recovery time improves circuit performance. The Vishay variants are ROHS3 compliant with -55°C to 150°C operating range. The Diotec UF4004 operates to 175°C but RoHS status is not applicable.
The BA157GP-E3/54 (Vishay General Semiconductor, SUPERECTIFIER® series) offers fast recovery with 1.3 V forward voltage drop and full -65°C to 175°C operating range, suitable for high-temperature applications requiring fast switching.
Compliance Considerations:
All recommended substitutes maintain 400 V reverse voltage and 1 A current ratings. Parts selected for ROHS3 compliance and Active product status ensure regulatory alignment and supply continuity. Operating temperature range must be verified against application requirements, particularly for UF4004-E3/53 and UF4004-E3/54 variants with -55°C to 150°C limits.
Frequently Asked Questions (FAQ)
Q: Can the 1N4004G be replaced with a fast recovery diode such as UF4004-E3/54?
A: Yes. The UF4004-E3/54 maintains the same 400 V reverse voltage and 1 A current ratings in a compatible DO-41 package. Fast recovery diodes reduce reverse recovery time, which improves switching performance in high-frequency applications. Forward voltage drop increases to 1 V at 1 A (identical to primary part), and operating temperature range is -55°C to 150°C. Verify application temperature requirements before substitution.
Q: What is the difference between standard recovery and fast recovery diodes in this product category?
A: Standard recovery diodes (1N4004G, GP10G-E3/54) exhibit recovery times greater than 500 ns and are suitable for low-frequency rectification and general-purpose applications. Fast recovery diodes (UF4004-E3/53, UF4004-E3/54, BA157GP-E3/54) have recovery times of 50 ns to 150 ns and are optimized for switching power supplies and higher-frequency circuits. Both types maintain identical voltage and current ratings.
Q: Are all substitute parts available in the same DO-41 package?
A: All substitute parts are available in through-hole axial packages designated as DO-41 or DO-204AL (DO-41). These packages are mechanically and electrically interchangeable for through-hole PCB mounting. Verify PCB footprint compatibility before assembly.
Q: What is the significance of forward voltage (Vf) differences among substitute parts?
A: Forward voltage drop affects power dissipation and circuit efficiency. The primary 1N4004G exhibits 1 V forward voltage at 1 A. Substitutes range from 1 V (UF4004-E3/53, UF4004-E3/54) to 1.3 V (BA157GP-E3/54). Higher forward voltage increases heat generation; lower forward voltage reduces power loss. Select based on thermal budget and efficiency requirements of the application.
Q: Which substitute parts are suitable for automotive applications?
A: The 1N4004G from Rectron USA includes AEC-Q101 automotive qualification. Other substitutes (1N4004G-T, UF4004-E3/53, UF4004-E3/54, GP10G-E3/54, BA157GP-E3/54) are Active status and ROHS3 compliant but do not specify automotive qualification in the provided data. Verify automotive requirements with manufacturer documentation if AEC-Q101 certification is mandatory.
Q: What is the operating temperature range limitation for UF4004-E3/53 and UF4004-E3/54?
A: These Vishay parts operate from -55°C to 150°C, which is narrower than the primary 1N4004G range of -65°C to 175°C. Applications requiring operation below -55°C or above 150°C must use alternative substitutes such as 1N4004G-T, GP10G-E3/54, or BA157GP-E3/54, which support the full -65°C to 175°C range.
Q: Is the Diotec UF4004 suitable for applications requiring ROHS3 compliance?
A: The Diotec UF4004 RoHS status is listed as "Not applicable." This part does not carry explicit ROHS3 certification. For applications with mandatory ROHS3 compliance requirements, select from Vishay or Diodes Incorporated variants (UF4004-E3/53, UF4004-E3/54, 1N4004G-T, GP10G-E3/54, BA157GP-E3/54), which are ROHS3 compliant.
Q: Can reverse leakage current differences affect circuit performance?
A: Reverse leakage current (Ir) ranges from 0.2 µA to 10 µA at 400 V among substitute parts. The primary 1N4004G exhibits 5 µA leakage. Higher leakage increases standby current consumption and heat generation in high-impedance circuits. The Rectron USA 1N4004G variant (0.2 µA) offers superior leakage performance. For low-power or high-impedance applications, verify leakage specifications against circuit requirements.
