1N4005/54 Equivalent & Substitute Parts

Part Overview

The 1N4005/54 is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 600 V DC reverse voltage and 1 A average rectified current in a DO-204AL (DO-41) axial through-hole package. This part is classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing design support and procurement continuity. Substitute parts must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating available packaging and product status options.

Substitute Part Grouping Explanation

Substitution eligibility for the 1N4005/54 is determined by the following critical parameters:

Mandatory Electrical Compatibility:

Voltage - DC Reverse (Vr) (Max): 600 V minimum
Current - Average Rectified (Io): 1 A minimum
Voltage - Forward (Vf) (Max) @ If: Must not exceed application requirements
Speed Classification: Standard or Fast Recovery acceptable
Current - Reverse Leakage @ Vr: Must not exceed 10 µA @ 600 V

Mandatory Mechanical Compatibility:

Mounting Type: Through Hole
Package / Case: DO-204AL (DO-41) Axial or equivalent axial configuration

Thermal Compatibility:

Operating Temperature - Junction: Minimum -50°C to maximum 150°C overlap required

Substitute parts are grouped into two categories: direct replacements maintaining identical electrical and package specifications, and functional equivalents with enhanced performance characteristics (such as faster recovery times) that remain electrically compatible within the application envelope.

Engineering Selection Recommendations

For Active Product Status with RoHS3 Compliance:

The 1N4005-TP (Micro Commercial Co) and 1N4005G-T (Diodes Incorporated) are recommended as primary substitutes. Both maintain identical electrical specifications to the 1N4005/54, offer ROHS3 compliance, and are actively manufactured. The 1N4005G-T provides extended operating temperature range (-65°C to 175°C) compared to the original part (-50°C to 150°C), supporting broader thermal applications.

For DO-204AL Package Retention:

The 1N4005G (Good-Ark Semiconductor) preserves the original DO-204AL package configuration while offering ROHS3 compliance and active product status. This option minimizes PCB layout modifications for existing designs.

For Enhanced Performance (Fast Recovery):

The 1N4937G (Taiwan Semiconductor Corporation) provides fast recovery characteristics (≤500ns, 200 ns typical) while maintaining 600 V / 1 A ratings and ROHS3 compliance. This substitute is suitable for applications requiring reduced reverse recovery time without electrical derating.

For Axial Package Configurations:

The 1N3613 (Microchip Technology) and 1N4247 (Microchip Technology) offer axial through-hole packages with extended temperature ranges (-65°C to 175°C) and active product status. The 1N3613 maintains standard recovery characteristics identical to the original part.

Parts Not Recommended for New Designs:

The 1N4005RLG and 1N4937RLG (onsemi) carry "Not For New Designs" status and should be avoided for new development projects, despite ROHS3 compliance and active inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the 1N4005/54 be directly replaced with the 1N4005-TP?

A: Yes. The 1N4005-TP maintains identical electrical specifications (600 V, 1 A, standard recovery) and compatible DO-41 package. Both are through-hole axial configurations. The 1N4005-TP offers ROHS3 compliance and active product status, addressing the obsolescence of the original part.

Q: What is the difference between standard and fast recovery diodes in this family?

A: Standard recovery diodes (1N4005 series) exhibit reverse recovery times exceeding 500 ns, suitable for general-purpose rectification. Fast recovery diodes (1N4937 series) exhibit reverse recovery times of 200–300 ns, reducing switching losses in high-frequency applications. Both maintain 600 V / 1 A ratings and are electrically compatible for applications not sensitive to recovery time.

Q: Are axial and DO-41 packages interchangeable?

A: Axial and DO-41 (DO-204AL) are equivalent package designations for through-hole diodes with identical lead spacing and mounting characteristics. Parts specified as "Axial" or "DO-41" are mechanically interchangeable on standard PCB layouts. Verify supplier device package designation to confirm exact lead configuration.

Q: Why do some substitutes show lower reverse leakage current (1 µA vs. 5 µA)?

A: Lower reverse leakage current indicates improved semiconductor material quality or manufacturing process. Parts with 1 µA leakage (Microchip 1N3613, 1N4247, 1N4946) are functionally superior and remain fully compatible with applications designed for 5 µA leakage specifications.

Q: Which substitute offers the widest operating temperature range?

A: The 1N4005G-T (Diodes Incorporated), 1N3613 (Microchip), 1N4247 (Microchip), and 1N4946 (Microchip) all support -65°C to 175°C operating range, compared to the original -50°C to 150°C. This extended range accommodates industrial and automotive thermal environments.

Q: Is RoHS3 compliance mandatory for substitution?

A: RoHS3 compliance is not mandatory for electrical substitution but is required for new designs in regulated markets (EU, China, Japan). The 1N4005-TP, 1N4005G, 1N4005G-T, 1N4937G, 1N4937RLG, and 1N4005RLG all offer ROHS3 compliance. Non-compliant alternatives (1N3613, 1N4247, 1N4946) remain electrically valid for legacy systems.

Q: Can the 1N4247 or 1N4946 be used as direct replacements?

A: The 1N4247 and 1N4946 are functionally compatible but not direct replacements. Both are fast recovery diodes with forward voltage specifications measured at different current levels (1N4247: 1.3 V @ 3 A; 1N4946: 1.3 V @ 1 A). They maintain 600 V / 1 A ratings and axial packages but exhibit different recovery characteristics. Use only when fast recovery performance is required or acceptable.

Q: What inventory considerations apply to these substitutes?

A: The 1N4005-TP (Micro Commercial Co) offers the highest inventory availability (110,625 pcs), followed by 1N4005G-T (Diodes Incorporated, 21,675 pcs) and 1N4005G (Good-Ark, 5,100 pcs). For time-sensitive procurement, the 1N4005-TP is the most readily available substitute.
