Equivalent & Substitute Parts for 2A04-TP General Purpose Rectifier Diode

Part Overview

The 2A04-TP is a general purpose rectifier diode manufactured by Micro Commercial Co, rated for 400 V DC reverse voltage with 2 A average rectified current in a DO-15 through-hole package. This component is classified as obsolete, which necessitates identification of active equivalent and substitute parts for ongoing design support and procurement continuity. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts satisfy the core functional requirements within the allowed parameter ranges for this diode category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2A04-TP is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Voltage - DC Reverse (Vr) (Max): Must equal or exceed 400 V
• Current - Average Rectified (Io): Must equal or exceed 2 A
• Voltage - Forward (Vf) (Max) @ If: Must not exceed 1 V @ 2 A
• Speed: Must maintain Standard Recovery >500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: Must not exceed 5 µA @ 400 V
• Operating Temperature - Junction: Must span -55°C to 150°C

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole (required)
• Package / Case: DO-204AC, DO-15, or Axial (interchangeable)

Compliance Criteria:

• RoHS Status: ROHS3 Compliant (required)
• Moisture Sensitivity Level: 1 (Unlimited) (required)

Substitute parts are classified into two groups: parametric equivalents (identical electrical and mechanical specifications) and similar alternatives (meeting minimum functional requirements with reduced current rating).

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalents (Direct Replacement):

The 2A04G and 2A04GH from Taiwan Semiconductor Corporation are parametric equivalents to the 2A04-TP. Both parts maintain identical electrical specifications (400 V, 2 A, 1 V forward voltage) and mechanical compatibility (DO-15 through-hole package). Both are active products with ROHS3 compliance and unlimited moisture sensitivity rating. The 2A04GH carries automotive-grade qualification (AEC-Q101), suitable for applications requiring automotive-level reliability. The 2A04G is available without automotive qualification. Both parts are available in higher inventory quantities than the obsolete 2A04-TP.

Similar Alternative (Reduced Current Rating):

The 1N5395GHA0G from Taiwan Semiconductor Corporation is a similar alternative with a reduced average rectified current rating of 1.5 A compared to the 2A04-TP's 2 A specification. This part maintains the 400 V reverse voltage rating, standard recovery speed, and identical reverse leakage characteristics. The 1N5395GHA0G carries automotive-grade qualification (AEC-Q101) and is suitable for applications where the 1.5 A current rating is sufficient. This part is not a direct replacement for designs requiring the full 2 A current capacity.

Compliance and Availability:

All substitute parts are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), matching the environmental compliance profile of the 2A04-TP. All substitute parts are active products with established supply chains, providing long-term procurement stability compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can the 2A04G or 2A04GH be used as direct replacements for the 2A04-TP?

A: Yes. The 2A04G and 2A04GH are parametric equivalents with identical electrical ratings (400 V, 2 A) and mechanical packaging (DO-15 through-hole). Both are pin-compatible and functionally interchangeable. The primary difference is product status (active versus obsolete) and, in the case of 2A04GH, automotive-grade qualification.

Q: What is the difference between 2A04G and 2A04GH?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The 2A04GH carries automotive-grade qualification (AEC-Q101) and is designated for automotive applications. The 2A04G does not carry automotive qualification. Selection depends on application requirements and qualification mandates.

Q: Can the 1N5395GHA0G replace the 2A04-TP?

A: The 1N5395GHA0G is a similar alternative, not a direct equivalent. It maintains the 400 V reverse voltage rating and identical reverse leakage characteristics but has a reduced average rectified current rating of 1.5 A versus the 2A04-TP's 2 A. This part is suitable only for applications where the 1.5 A current capacity is sufficient.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts (2A04G, 2A04GH, and 1N5395GHA0G) are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), matching the environmental compliance of the 2A04-TP.

Q: What is the package compatibility between these parts?

A: All parts use the DO-15 through-hole axial package (DO-204AC designation). The parts are mechanically and electrically interchangeable in terms of package form factor and pin configuration.

Q: Which substitute part should be selected for new designs?

A: For applications requiring the full 2 A current rating, select either 2A04G or 2A04GH. For automotive applications or designs requiring AEC-Q101 qualification, select 2A04GH. For general-purpose applications without automotive requirements, 2A04G is suitable. The 1N5395GHA0G is appropriate only for applications with 1.5 A or lower current requirements.
