PR1507G-T Equivalent & Substitute Parts

Part Overview

The PR1507G-T is a general-purpose rectifier diode manufactured by Diodes Incorporated, rated for 1000 V DC reverse voltage and 1.5 A average rectified current in a DO-15 (DO-204AC) axial through-hole package. This component is classified as obsolete, indicating discontinued production by the original manufacturer. Identification of equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for repair, maintenance, and new production applications where this diode specification is required.

Substitute Part Grouping Explanation

Substitution of the PR1507G-T is determined by the following critical parameters:

Mandatory Matching Criteria:

Voltage - DC Reverse (Vr) (Max): 1000 V
Current - Average Rectified (Io): 1.5 A minimum
Mounting Type: Through Hole
Package / Case: DO-204AC (DO-15) or compatible axial configuration

Acceptable Variation Parameters:

Voltage - Forward (Vf): Substitute parts may vary within design tolerance; values up to 1.4 V are acceptable for general-purpose rectification
Reverse Recovery Time (trr): Substitute parts may have different recovery characteristics (fast recovery ≤500 ns or standard recovery >500 ns); both are functionally acceptable
Operating Temperature Range: Substitute parts with extended or equivalent temperature ranges are acceptable
Current - Reverse Leakage: All substitute parts maintain 5 µA @ 1000 V specification

Package Compatibility:

Primary substitutes use DO-204AC (DO-15) axial package, identical to the original
Secondary substitutes use DO-204AL (DO-41) axial package, which is mechanically compatible but requires board layout verification

Substitute parts are grouped into two categories: direct equivalents (identical package and electrical characteristics) and functional equivalents (same voltage and current ratings with different recovery characteristics or package variants).

Engineering Selection Recommendations

Direct Equivalents (Recommended Primary Substitutes):

RGP15M-E3/54, FR157GP-AP, and FR157GP-TP are direct functional equivalents to the PR1507G-T. These parts maintain identical voltage and current ratings, matching forward voltage characteristics, and fast recovery time specifications. All three are in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. RGP15M-E3/54 offers extended operating temperature range (-65°C ~ 175°C) compared to the original specification. FR157GP-AP and FR157GP-TP are identical electrically and differ only in packaging format (loose vs. tape and reel).

Secondary Equivalents (Functional Substitutes):

1N5399GP-E3/73 and GP15M-E3/54 and GP15M-E3/73 are functionally equivalent with the same voltage and current ratings but exhibit different recovery characteristics. 1N5399GP-E3/73 maintains the DO-15 package format with extended temperature range. GP15M series parts feature lower forward voltage (1.1 V @ 1.5 A) and extended temperature range, making them suitable for applications where reduced power dissipation is beneficial.

Package Variant Substitutes:

1N5399-E3/54 and 1N5399-E3/73 use the DO-204AL (DO-41) axial package instead of DO-15. These parts are electrically equivalent but require verification of board layout compatibility due to different lead spacing and physical dimensions.

Higher Current Alternative:

HER208G-TP is rated for 2 A average rectified current in the same DO-15 package. This part is suitable only for applications where the 1.5 A rating is insufficient; it is not a direct substitute for the PR1507G-T due to higher current specification and different forward voltage characteristics.

All recommended substitutes are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS coding (8541.10.0080).

Frequently Asked Questions (FAQ)

Q: Can RGP15M-E3/54 directly replace PR1507G-T without circuit modification?

A: Yes. RGP15M-E3/54 is a direct equivalent with identical voltage (1000 V), current (1.5 A), forward voltage (1.3 V @ 1.5 A), and recovery time (500 ns) specifications. The DO-15 package is identical. Extended temperature range (-65°C ~ 175°C) provides additional margin beyond the original specification.

Q: What is the difference between FR157GP-AP and FR157GP-TP?

A: Both parts are electrically identical with matching voltage, current, and recovery characteristics. The difference is packaging format: FR157GP-AP is supplied loose, while FR157GP-TP is supplied in tape and reel format. Selection depends on procurement and assembly requirements.

Q: Why do 1N5399-E3/54 and 1N5399-E3/73 use a different package (DO-41)?

A: These parts use the DO-204AL (DO-41) axial package instead of DO-15. While electrically equivalent, the physical dimensions and lead spacing differ. Board layout verification is required before substitution to confirm mechanical compatibility with existing footprints.

Q: Can GP15M-E3/54 be used as a direct replacement?

A: GP15M-E3/54 is functionally equivalent for voltage and current ratings but exhibits different electrical characteristics: lower forward voltage (1.1 V vs. 1.3 V) and longer recovery time (3.5 µs vs. 500 ns). These differences are acceptable in general-purpose rectification applications but may affect performance in high-frequency switching circuits.

Q: Is HER208G-TP a suitable substitute?

A: HER208G-TP is not a direct substitute. While it shares the same 1000 V voltage rating and DO-15 package, it is rated for 2 A average rectified current instead of 1.5 A. This part is suitable only for applications requiring higher current capacity. Forward voltage (1.7 V @ 2 A) and recovery time (75 ns) also differ significantly.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, matching the compliance status of the original PR1507G-T.

Q: What is the primary reason to select a substitute for PR1507G-T?

A: The PR1507G-T is classified as obsolete, indicating discontinued production by Diodes Incorporated. Substitute parts from active manufacturers (Vishay General Semiconductor and Micro Commercial Co) ensure continued component availability for production and maintenance applications.

Q: Do all substitutes have the same operating temperature range?

A: No. The original PR1507G-T operates from -65°C ~ 150°C. RGP15M-E3/54, 1N5399GP-E3/73, GP15M-E3/54, and GP15M-E3/73 offer extended ranges up to 175°C. FR157GP-AP and FR157GP-TP operate from -55°C ~ 150°C. 1N5399-E3/54 and 1N5399-E3/73 operate from -50°C ~ 150°C. Selection should verify application temperature requirements.
