Equivalent & Substitute Parts for 1N4002 TR General Purpose Rectifier Diode

Part Overview

The 1N4002 TR is a general purpose rectifier diode manufactured by Central Semiconductor Corp, rated for 100 V DC reverse voltage and 1 A average rectified current in a through-hole DO-41 package. This part is classified as obsolete, which necessitates identification of active equivalent and substitute components for new designs and ongoing production support.

The 1N4002 series serves applications requiring standard recovery rectification in power supply circuits, signal demodulation, and general switching applications. Due to its obsolete status, equivalent parts with active product status are required for design continuity and supply chain reliability.

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

Select from the following active parts for direct electrical and mechanical substitution:

1N4002-E3/54 (Vishay General Semiconductor): Active status, ROHS3 compliant, 78,691 units in stock. Recommended for high-volume procurement.
1N4002-E3/73 (Vishay General Semiconductor): Active status, ROHS3 compliant, 27,360 units in stock. Alternative sourcing option.
1N4002-G (Comchip Technology): Active status, ROHS3 compliant, 13,557 units in stock. Secondary sourcing option.
1N4002E-E3/53 (Vishay General Semiconductor): Active status, ROHS3 compliant, 16,682 units in stock.
1N4002E-E3/54 (Vishay General Semiconductor): Active status, ROHS3 compliant, Tape & Reel format, 811 units in stock.
1N4002G A0G (Taiwan Semiconductor Corporation): Active status, ROHS3 compliant, Tape & Box format, 752 units in stock.

For Voltage-Rated Upgrade:

1N4007 TR (Central Semiconductor Corp): Active status, ROHS3 compliant. Provides 1000 V reverse voltage rating with identical 1 A current and forward voltage characteristics. Suitable for applications requiring higher reverse voltage margin or where 100 V rating is marginal.

Packaging Format Considerations:

Cut Tape (CT) format: Suitable for manual assembly and small-batch production.
Tape & Reel (TR) format: Required for automated pick-and-place assembly.
Tape & Box (TB) format: Intermediate packaging option.

Compliance Status:

All recommended active substitutes carry ROHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory requirements. The original 1N4002 TR carries REACH Unaffected status but lacks ROHS3 compliance due to its obsolete classification.

Frequently Asked Questions (FAQ)

Q: Can the 1N4007 TR be used as a direct replacement for the 1N4002 TR?

A: The 1N4007 TR is electrically compatible as a substitute. It maintains identical current (1 A) and forward voltage (1.1 V @ 1 A) specifications while providing higher reverse voltage rating (1000 V vs. 100 V). This upgrade is suitable for applications where the 100 V rating is adequate or where higher voltage margin is beneficial. No circuit modification is required.

Q: What is the difference between DO-41 and DO-204AL package designations?

A: DO-41 and DO-204AL are equivalent package designations for the same through-hole axial diode form factor. Both refer to a cylindrical component with axial leads. The designations are interchangeable for mechanical and electrical purposes.

Q: Are all listed substitute parts ROHS3 compliant?

A: All substitute parts listed with active product status carry ROHS3 compliance certification. The original 1N4002 TR is classified as REACH Unaffected but does not carry ROHS3 compliance due to its obsolete status. For new designs and production requiring ROHS3 compliance, select from the active substitute parts.

Q: What is the significance of the packaging format suffix (CT, TR, TB)?

A: Packaging format indicates the supply method: Cut Tape (CT) for manual handling, Tape & Reel (TR) for automated assembly equipment, and Tape & Box (TB) for intermediate applications. Electrical and mechanical specifications remain identical across formats. Selection depends on assembly process requirements.

Q: Can 1N4002-TP from Micro Commercial Co be used as a substitute?

A: The 1N4002-TP meets electrical and mechanical specifications but carries "Not For New Designs" product status. It is suitable for legacy system maintenance and repair but should not be selected for new product designs. Prefer parts with active status for new applications.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by: (1) Voltage - DC Reverse (Vr) rating of 100 V or higher, (2) Current - Average Rectified (Io) of 1 A or higher, (3) Forward voltage (Vf) not exceeding 1.1 V @ 1 A, (4) Standard recovery speed characteristics, (5) Through-hole mounting type, and (6) DO-41 or DO-204AL package compatibility. All listed substitutes meet these criteria.

Q: Is the 1N4002G A0G from Taiwan Semiconductor Corporation a suitable replacement?

A: Yes. The 1N4002G A0G meets all electrical specifications with forward voltage of 1.0 V @ 1 A (superior to the 1.1 V maximum), carries active product status, and is ROHS3 compliant. It is supplied in Tape & Box format and is suitable for applications where this packaging format is acceptable.
