Substitute Part Grouping Explanation

Substitution of the PR1505G-T is determined by strict electrical and mechanical parameter matching within the following criteria:

Primary Substitution Parameters:

Voltage - DC Reverse (Vr) (Max): 600 V (exact match required)
Current - Average Rectified (Io): 1.5 A minimum (equal or higher acceptable)
Mounting Type: Through Hole (required)
Package / Case: DO-15 or DO-204AC compatible (required)
Forward Voltage (Vf): 1.3 V or lower at rated current (preferred for thermal performance)
Reverse Recovery Time (trr): ≤ 500 ns (fast recovery classification)
Reverse Leakage Current: 5 µA @ 600 V (standard specification)

Secondary Considerations:

Product Status: Active status preferred for long-term availability
RoHS Compliance: ROHS3 Compliant (regulatory requirement)
Operating Temperature Range: Extended range acceptable if minimum -65°C and maximum ≥ 150°C maintained

Substitute parts are grouped into two categories: direct electrical equivalents (matching all primary parameters) and functional alternatives (meeting core electrical requirements with acceptable parameter variations).

Engineering Selection Recommendations

Tier 1 - Direct Electrical Equivalents (Recommended Primary Substitutes):

RGP15J-E3/54 (Vishay) and FR155GP-TP (Micro Commercial Co) are the preferred direct substitutes for the PR1505G-T. Both parts maintain identical electrical specifications: 600 V reverse voltage, 1.5 A average rectified current, 1.3 V forward voltage at rated current, and 250 ns reverse recovery time. Both are active products with ROHS3 compliance and extended operating temperature ranges (-65°C to 175°C and -55°C to 150°C respectively). RGP15J-E3/54 is supplied in Cut Tape packaging with 8,958 units in stock, while FR155GP-TP is supplied in Tape & Reel with 1,019 units in stock. These parts are electrically and mechanically interchangeable with the PR1505G-T.

Tier 2 - Functional Equivalents with Parameter Variations:

GP15J-E3/54 and GP15J-E3/73 (Vishay SUPERECTIFIER® series) provide functional equivalence with lower forward voltage (1.1 V @ 1.5 A) and extended temperature range (-65°C to 175°C). These parts employ standard recovery characteristics (3.5 µs reverse recovery time) rather than fast recovery, making them suitable for applications where switching speed is not critical. Both are active products with ROHS3 compliance and high inventory availability (9,037 and 4,200 units respectively).

Tier 3 - Higher Current Alternative:

2A05G A0G (Taiwan Semiconductor Corporation) provides a 2 A rated current at 600 V with fast recovery characteristics and improved forward voltage performance (1 V @ 2 A). This part is suitable for applications requiring higher current capacity while maintaining the same voltage rating and package compatibility. It is an active product with ROHS3 compliance.

Package Compatibility Note:

1N5397-E3/54 (Vishay) is not recommended as a direct substitute due to package incompatibility. This part uses DO-204AL (DO-41) package, which differs from the DO-15 package of the PR1505G-T. Additionally, it exhibits standard recovery characteristics (2 µs reverse recovery time) and higher forward voltage (1.4 V @ 1.5 A).

Frequently Asked Questions (FAQ)

Q: Can RGP15J-E3/54 be used as a direct replacement for PR1505G-T?

A: Yes. RGP15J-E3/54 meets all electrical and mechanical requirements of the PR1505G-T. Both parts are rated for 600 V reverse voltage, 1.5 A average rectified current, feature identical forward voltage (1.3 V @ 1.5 A), and use compatible DO-15 through-hole packages. RGP15J-E3/54 is an active product with extended temperature range and ROHS3 compliance.

Q: What is the difference between fast recovery and standard recovery diodes in this comparison?

A: Fast recovery diodes (PR1505G-T, RGP15J-E3/54, 2A05G A0G, FR155GP-AP, FR155GP-TP) have reverse recovery times ≤ 500 ns, enabling faster switching transitions. Standard recovery diodes (1N5397-E3/54, GP15J-E3/54, GP15J-E3/73) have reverse recovery times > 500 ns (ranging from 2 µs to 3.5 µs), suitable for lower-frequency applications. Selection depends on circuit switching frequency requirements.

Q: Is the 2A05G A0G suitable for applications designed for the PR1505G-T?

A: 2A05G A0G is functionally suitable for PR1505G-T applications. It maintains the same 600 V reverse voltage rating and DO-15 package compatibility. The higher 2 A current rating provides design margin and is backward-compatible with 1.5 A circuits. Forward voltage is lower (1 V @ 2 A), reducing thermal dissipation. Fast recovery characteristics match the original specification.

Q: Why is 1N5397-E3/54 not recommended as a substitute?

A: 1N5397-E3/54 uses a DO-204AL (DO-41) package, which is physically incompatible with the DO-15 package of the PR1505G-T. Additionally, it exhibits standard recovery characteristics (2 µs) and higher forward voltage (1.4 V @ 1.5 A), making it unsuitable for applications requiring fast recovery performance.

Q: What is the difference between GP15J-E3/54 and GP15J-E3/73?

A: GP15J-E3/54 and GP15J-E3/73 are electrically identical, both rated for 600 V, 1.5 A with 1.1 V forward voltage and 3.5 µs reverse recovery time. The primary difference is packaging: GP15J-E3/54 is supplied in Cut Tape (CT), while GP15J-E3/73 is supplied in Tape & Box (TB). Selection depends on procurement and assembly requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (RGP15J-E3/54, 1N5397-E3/54, 2A05G A0G, FR155GP-AP, FR155GP-TP, GP15J-E3/54, GP15J-E3/73) are ROHS3 compliant, matching the compliance status of the PR1505G-T.

Q: What is the operating temperature range consideration for substitution?

A: The PR1505G-T operates from -65°C to 150°C. Most substitute parts extend the upper temperature limit to 175°C (RGP15J-E3/54, GP15J-E3/54, GP15J-E3/73) or maintain 150°C (2A05G A0G, FR155GP-AP, FR155GP-TP). All substitutes meet or exceed the original temperature range, providing thermal design margin.

Q: Can FR155GP-AP and FR155GP-TP be used interchangeably?

A: FR155GP-AP and FR155GP-TP are electrically identical, both rated for 600 V, 1.5 A with 1.3 V forward voltage and 250 ns reverse recovery time. The difference is packaging: FR155GP-AP is supplied without specified packaging format, while FR155GP-TP is supplied in Tape & Reel (TR). Selection depends on assembly and procurement requirements.
