Substitute Part Grouping Explanation
Substitution of the 1N4002GL TR is determined by strict equivalence across the following electrical and mechanical parameters:
Critical Substitution Criteria:
- Voltage - DC Reverse (Vr) (Max): 100 V
- Current - Average Rectified (Io): 1 A
- Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A (tolerance ±0.1 V acceptable)
- Speed: Standard Recovery >500ns, > 200mA (Io)
- Current - Reverse Leakage @ Vr: 5 µA @ 100 V (tolerance ±5 µA acceptable)
- Mounting Type: Through Hole
- Package / Case: DO-204AL, DO-41, or Axial
- Operating Temperature - Junction: -65°C to 175°C minimum
Substitute parts are grouped into two categories:
Parametric Equivalents: Parts from Central Semiconductor Corp and Vishay General Semiconductor that maintain all electrical specifications and active product status.
Direct Manufacturer Equivalent: Taiwan Semiconductor Corporation 1N4002G, which meets all electrical parameters with minor operating temperature variation (-55°C to 150°C).
Alternative Equivalent: onsemi 1N4002RLG and Vishay GP10B-E3/54 / GP10BE-E3/54 series, which maintain electrical specifications with different base product designations.

Engineering Selection Recommendations
Primary Substitutes (Recommended for New Designs):
1N4002SP TR TIN/LEAD (Central Semiconductor Corp) and 1N4002GPE-E3/54 (Vishay General Semiconductor) are the preferred substitutes. Both maintain full electrical equivalence to the 1N4002GL TR, offer active product status, and provide ROHS3 compliance with unlimited moisture sensitivity rating. These parts ensure long-term supply chain stability and regulatory compliance.
Secondary Substitutes (Active Status, Full Equivalence):
1N4002GP-E3/54, 1N4002GPE-E3/73, GP10B-E3/54, and GP10BE-E3/54 from Vishay General Semiconductor provide identical electrical performance and active product status. These alternatives are suitable for applications where supply diversification is required.
Alternative Substitute (Limited Recommendation):
1N4002G from Taiwan Semiconductor Corporation meets all electrical specifications with a reduced operating temperature range (-55°C to 150°C). This part is suitable only for applications operating within this temperature window.
Not Recommended for New Designs:
1N4002RLG (onsemi) carries "Not For New Designs" status and exhibits higher reverse leakage current (10 µA @ 100 V versus 5 µA @ 100 V). This part should be used only for legacy system maintenance where existing designs require compatibility.
Frequently Asked Questions (FAQ)
Q: Can 1N4002SP TR TIN/LEAD directly replace 1N4002GL TR in existing circuits?
A: Yes. Both parts maintain identical electrical specifications: 100 V reverse voltage, 1 A average rectified current, 1.1 V forward voltage drop at 1 A, and standard recovery speed. The primary difference is product status (active versus obsolete) and packaging format (Cut Tape versus original packaging).
Q: What is the difference between 1N4002GP-E3/54 and 1N4002GPE-E3/54?
A: Both parts are manufactured by Vishay General Semiconductor and maintain identical electrical specifications. The designation difference reflects internal Vishay product line organization. Both are suitable substitutes with equivalent performance.
Q: Is 1N4002G from Taiwan Semiconductor Corporation a suitable replacement?
A: 1N4002G is electrically equivalent for voltage and current ratings. However, its operating temperature range is -55°C to 150°C, compared to -65°C to 175°C for the original part. Use this substitute only if your application operates within the -55°C to 150°C window.
Q: Why is 1N4002RLG marked "Not For New Designs"?
A: onsemi has designated this part for legacy support only. While it meets the core electrical specifications, the higher reverse leakage current (10 µA versus 5 µA) and discontinued status make it unsuitable for new circuit designs. Use only for maintaining existing systems.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All active substitute parts listed carry ROHS3 compliance certification. The original 1N4002GL TR is marked as REACH Unaffected, and all substitutes maintain this regulatory status.
Q: What is the difference between DO-41 and DO-204AL packaging?
A: DO-41 and DO-204AL are equivalent designations for the same axial through-hole package. All listed substitutes use this identical package format, ensuring mechanical compatibility in PCB layouts.
Q: Can I use GP10B-E3/54 or GP10BE-E3/54 instead of 1N4002 series parts?
A: Yes. GP10B and GP10BE are alternative product designations from Vishay's SUPERECTIFIER® line that maintain identical electrical specifications to the 1N4002 series. These parts are functionally interchangeable in circuit applications.
Q: What inventory levels are available for the recommended substitutes?
A: 1N4002SP TR TIN/LEAD: 5,811 pcs; 1N4002GPE-E3/54: 11,782 pcs; 1N4002GPE-E3/73: 9,935 pcs; 1N4002GP-E3/54: 38,771 pcs. These quantities support both immediate requirements and long-term production planning.
