2A03-TP Equivalent & Substitute Parts

Part Overview

The 2A03-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 200 V DC reverse voltage and 2 A average rectified current in a DO-15 through-hole package. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. The 2A03-TP employs standard recovery technology with forward voltage characteristics of 1 V maximum at 2 A, suitable for general rectification applications requiring moderate current capacity and voltage rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2A03-TP is determined by the following critical electrical and mechanical parameters:

Voltage Rating Compatibility: The substitute part must maintain a DC reverse voltage rating of 200 V or higher to ensure safe operation within the original circuit design envelope.

Current Rating Compatibility: The substitute part must support an average rectified current rating equal to or greater than 2 A. Parts with lower current ratings do not qualify as direct substitutes.

Package Compatibility: The substitute part must utilize the DO-15 through-hole axial package to ensure mechanical fit and thermal characteristics equivalent to the original component.

Recovery Characteristics: The substitute part may employ either standard or fast recovery technology, as both are compatible with general-purpose rectification applications.

Temperature Range: The substitute part must support the operating junction temperature range of -55°C to 150°C or a range that encompasses this specification.

Compliance Requirements: The substitute part must maintain ROHS3 compliance and EAR99 classification to satisfy regulatory and export requirements.

The PR1503-T from Diodes Incorporated meets all substitution criteria with the exception of current rating, which is specified at 1.5 A rather than 2 A. This represents a current derating of 25% from the original specification.

Parameter Comparison

Engineering Selection Recommendations

The PR1503-T from Diodes Incorporated qualifies as a functional substitute for the obsolete 2A03-TP based on matching voltage rating, package configuration, and regulatory compliance. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Current Rating Consideration: The PR1503-T is rated for 1.5 A average rectified current compared to the 2A03-TP specification of 2 A. Circuit designs operating at or near the 2 A maximum rating of the original part require thermal and current load analysis to confirm acceptable operation at the reduced 1.5 A rating of the substitute.

Forward Voltage Characteristic: The PR1503-T exhibits a maximum forward voltage of 1.2 V at 1.5 A, compared to 1 V at 2 A for the 2A03-TP. This difference affects power dissipation calculations and thermal management in the application circuit.

Recovery Speed: The PR1503-T employs fast recovery technology with a reverse recovery time of 150 ns, compared to standard recovery characteristics of the original part. Fast recovery diodes are compatible with general-purpose rectification applications and offer improved switching performance.

Temperature Range: The PR1503-T supports an extended low-temperature operating range of -65°C to 150°C, providing additional margin below the -55°C minimum of the original specification.

Compliance and Availability: Both parts maintain ROHS3 compliance and EAR99 classification. The PR1503-T is available in active production with documented inventory, whereas the 2A03-TP is obsolete.

Frequently Asked Questions (FAQ)

Q: Can the PR1503-T directly replace the 2A03-TP in all applications?

A: The PR1503-T is mechanically and electrically compatible for applications where the circuit current demand does not exceed 1.5 A. Applications requiring the full 2 A rating of the original part require circuit analysis to confirm acceptable operation at the reduced current rating of the substitute.

Q: What is the impact of the higher forward voltage in the PR1503-T?

A: The forward voltage difference of 0.2 V (1.2 V versus 1 V) results in increased power dissipation across the diode. In a 2 A circuit, this represents an additional 0.4 W of heat generation. Thermal design review is necessary for applications with tight thermal budgets.

Q: Are the DO-15 packages of both parts physically identical?

A: Both the 2A03-TP and PR1503-T utilize the DO-204AC, DO-15 axial through-hole package. Physical dimensions and lead spacing are equivalent, permitting direct mechanical substitution on printed circuit boards.

Q: Does the faster recovery speed of the PR1503-T affect circuit performance?

A: Fast recovery diodes are suitable for general-purpose rectification applications. The 150 ns reverse recovery time of the PR1503-T is compatible with standard power supply and rectification circuits. No circuit modification is required due to the faster recovery characteristic.

Q: What compliance certifications apply to both parts?

A: Both the 2A03-TP and PR1503-T are ROHS3 compliant and classified as EAR99 for export control purposes. Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity precautions are required during handling and storage.

Q: Is the PR1503-T available in the same packaging format as the 2A03-TP?

A: The 2A03-TP is supplied in bulk packaging, while the PR1503-T is supplied in Tape & Reel (TR) format. Both formats are compatible with standard component handling and assembly processes. Tape & Reel packaging is standard for active production components.
