Substitute Part Grouping Explanation
Substitution of the 1N4002RL is determined by the following critical parameters:
Mandatory Matching Criteria:
- Voltage - DC Reverse (Vr) (Max): 100 V minimum
- Current - Average Rectified (Io): 1 A minimum
- Mounting Type: Through Hole
- Package / Case: DO-204AL or DO-41 compatible
Acceptable Variation Ranges:
- Voltage - Forward (Vf) (Max) @ If: 0.95 V to 1.3 V @ 1 A
- Current - Reverse Leakage @ Vr: 5 µA to 10 µA @ 100 V
- Speed: Standard Recovery (>500ns) or Fast Recovery (≤500ns)
- Operating Temperature - Junction: Minimum -55°C, Maximum 150°C or higher
Substitute parts meeting these criteria are functionally compatible with the 1N4002RL in standard rectification applications. Parts with higher voltage ratings (e.g., 1N4007G-T at 1000 V) are included as they provide backward compatibility while exceeding the original specification.

Engineering Selection Recommendations
Direct Equivalents (Identical Electrical Specifications):
1N4002RLG (onsemi) is the direct equivalent to 1N4002RL, maintaining identical electrical parameters. However, 1N4002RLG is classified as "Not For New Designs," indicating limited future availability. This part is ROHS3 compliant, addressing environmental compliance requirements absent in the original 1N4002RL.
Active Production Alternatives (Recommended for New Designs):
1N4002-E3/54 (Vishay General Semiconductor - Diodes Division) and 1N4002G-T (Diodes Incorporated) are active production parts with identical 100 V / 1 A ratings and standard recovery characteristics. Both are ROHS3 compliant and suitable for long-term supply chain stability. 1N4002G-T extends the operating temperature range to -65°C to 175°C, matching the original 1N4002RL specification.
1N4002G (Taiwan Semiconductor Corporation) is an active alternative with marginally lower forward voltage (1.0 V vs. 1.1 V) and reduced reverse leakage (5 µA vs. 10 µA), providing improved performance characteristics within the same package and voltage class.
Fast Recovery Alternatives:
EGP10B (Fairchild Semiconductor) and RGP10B (Fairchild Semiconductor) offer fast recovery characteristics (≤500ns vs. >500ns standard recovery). These parts are suitable for applications requiring reduced reverse recovery time while maintaining 100 V / 1 A ratings. RGP10B matches the original temperature range (-65°C to 175°C).
Higher Voltage Backward-Compatible Option:
1N4007G-T (Diodes Incorporated) provides 1000 V reverse voltage rating with identical 1 A current capacity. This part is suitable for applications where the 1N4002RL is used but higher voltage margin is required. It is active production, ROHS3 compliant, and rated to -65°C to 175°C.
Obsolescence Mitigation:
Parts classified as "Last Time Buy" (1N4002-T) or "Not For New Designs" (1N4002RLG, 1N4002-TP) should be avoided for new designs but remain acceptable for legacy system support where existing inventory is available.
Frequently Asked Questions (FAQ)
Q: Can 1N4002RLG directly replace 1N4002RL?
A: Yes. 1N4002RLG is the direct equivalent with identical electrical specifications: 100 V reverse voltage, 1 A average rectified current, 1.1 V forward voltage at 1 A, and standard recovery characteristics. The primary difference is packaging format (Cut Tape vs. unspecified) and RoHS compliance status (ROHS3 vs. non-compliant).
Q: What is the difference between standard recovery and fast recovery diodes?
A: Standard recovery diodes exhibit reverse recovery time greater than 500 ns, while fast recovery diodes exhibit reverse recovery time of 500 ns or less. Fast recovery diodes (EGP10B, RGP10B, 1N4934G) reduce switching losses in high-frequency applications but are not required for standard rectification at line frequency (50/60 Hz).
Q: Is 1N4007G-T a suitable replacement for 1N4002RL?
A: Yes, 1N4007G-T is functionally compatible. It maintains the 1 A current rating and standard recovery characteristics but provides 1000 V reverse voltage instead of 100 V. This higher voltage rating introduces no functional incompatibility in circuits designed for 100 V operation; the diode simply provides additional voltage margin. Use 1N4007G-T only if supply constraints on 100 V parts exist.
Q: Are all substitute parts available in the same axial through-hole package?
A: Yes. All listed substitute parts are rated for through-hole mounting in DO-204AL or DO-41 axial packages, ensuring mechanical and electrical compatibility with the original 1N4002RL footprint.
Q: Which substitute part is recommended for new designs?
A: 1N4002G-T (Diodes Incorporated) or 1N4002-E3/54 (Vishay) are recommended for new designs. Both are active production, ROHS3 compliant, and maintain identical electrical specifications to the 1N4002RL. 1N4002G-T extends the operating temperature range to -65°C to 175°C, matching the original part.
Q: What is the significance of RoHS compliance?
A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. The original 1N4002RL is RoHS non-compliant. Substitute parts with ROHS3 compliance are required for applications subject to environmental regulations in the European Union and other jurisdictions adopting equivalent standards.
Q: Can I use 1N4934G instead of 1N4002RL?
A: Yes, 1N4934G is electrically compatible. It maintains 100 V reverse voltage and 1 A current ratings but features fast recovery characteristics (≤500ns vs. >500ns). The forward voltage is slightly higher (1.2 V vs. 1.1 V). Use 1N4934G only if fast recovery characteristics are required or if standard recovery parts are unavailable.
Q: What does "Not For New Designs" mean?
A: "Not For New Designs" indicates the manufacturer is discontinuing the part and recommends against its use in new product development. These parts may have limited availability and no guaranteed long-term supply. They remain acceptable for legacy system maintenance and repair where existing inventory is available.
Q: Are there differences in reverse leakage current between substitute parts?
A: Yes. The original 1N4002RL specifies 10 µA reverse leakage at 100 V. Most substitute parts specify 5 µA at 100 V, representing improved leakage characteristics. Lower reverse leakage reduces standby current in circuits and improves performance in high-impedance applications. This difference is not functionally problematic in standard rectification circuits.
