FR152-TP Equivalent & Substitute Parts

Part Overview

The FR152-TP is a general-purpose rectifier diode rated for 100 V DC reverse voltage and 1.5 A average rectified current in a through-hole DO-15 package. Manufactured by Micro Commercial Co, this component is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary for new designs, production continuity, and long-term component availability.

Substitute Part Grouping Explanation

Substitute parts for the FR152-TP are classified into two categories based on electrical and mechanical parameter alignment:

Parametric Equivalents maintain identical electrical specifications including voltage rating (100 V), current rating (1.5 A), forward voltage (1.3 V @ 1.5 A), recovery time (150 ns), and reverse leakage (5 µA @ 100 V). These parts are direct replacements with matching performance characteristics and package compatibility (DO-15/DO-204AC).

Similar Alternatives share the same voltage rating (100 V) and through-hole mounting type but differ in one or more electrical parameters. These parts are suitable for applications where the specific parameter variation does not impact circuit performance.

The following parameters determine substitution eligibility:

Voltage - DC Reverse (Vr) (Max): Must equal 100 V
Current - Average Rectified (Io): Must equal or exceed 1.5 A
Mounting Type: Must be Through Hole
Package / Case: Must be compatible with DO-15 or DO-204AC
Operating Temperature Range: Must encompass -55°C ~ 150°C

Engineering Selection Recommendations

Direct Parametric Equivalents (Recommended for Direct Replacement)

FR152G and FR152GH from Taiwan Semiconductor Corporation are parametric equivalents with active product status. Both parts maintain identical electrical specifications to the FR152-TP, including 100 V reverse voltage, 1.5 A current rating, 1.3 V forward voltage at 1.5 A, 150 ns recovery time, and 5 µA reverse leakage. FR152GH includes AEC-Q101 automotive qualification, suitable for applications requiring automotive-grade components. Both are ROHS3 compliant and REACH unaffected.

PG151R_R2_00001 from Panjit International Inc. is a parametric equivalent with active status and ROHS3 compliance. This part matches all electrical specifications of the FR152-TP and offers improved reverse leakage performance (1 µA @ 100 V). It is supplied in Tape & Reel packaging.

Similar Alternative (Higher Current Rating)

FR202G B0G from Taiwan Semiconductor Corporation is rated for 2 A average rectified current while maintaining the 100 V voltage rating and fast recovery characteristics. This part is suitable for applications where the 1.5 A rating is marginal or where future design headroom is required. It maintains identical forward voltage (1.3 V @ 2 A) and recovery time (150 ns) specifications.

Alternative with Modified Recovery Characteristics

1N5392GHB0G from Taiwan Semiconductor Corporation is rated for 100 V and 1.5 A with active product status and AEC-Q101 automotive qualification. This part features standard recovery characteristics (>500ns) rather than fast recovery, resulting in lower forward voltage (1.1 V @ 1.5 A). Selection of this part is appropriate only when standard recovery speed is acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can FR152G or FR152GH be used as direct replacements for FR152-TP?

A: Yes. FR152G and FR152GH are parametric equivalents with identical voltage (100 V), current (1.5 A), forward voltage (1.3 V @ 1.5 A), recovery time (150 ns), and reverse leakage (5 µA @ 100 V) specifications. Both are active products with ROHS3 compliance. FR152GH includes AEC-Q101 automotive qualification.

Q: What is the difference between FR152G and FR152GH?

A: FR152GH includes AEC-Q101 automotive qualification and automotive-grade designation. Both parts are otherwise electrically and mechanically identical. Selection of FR152GH is required for automotive applications.

Q: Is PG151R_R2_00001 compatible with FR152-TP?

A: Yes. PG151R_R2_00001 is a parametric equivalent with identical electrical specifications. It offers superior reverse leakage performance (1 µA @ 100 V versus 5 µA @ 100 V). The primary difference is packaging format (Tape & Reel versus bulk).

Q: Can FR202G B0G replace FR152-TP?

A: FR202G B0G is a suitable substitute for applications where higher current capacity is beneficial. It maintains the 100 V voltage rating and fast recovery characteristics (150 ns) but is rated for 2 A instead of 1.5 A. This part is appropriate when design margins require higher current handling.

Q: Why does 1N5392GHB0G have lower forward voltage than FR152-TP?

A: 1N5392GHB0G features standard recovery characteristics (>500ns) rather than fast recovery. Standard recovery diodes typically exhibit lower forward voltage. This part is suitable only when standard recovery speed meets application requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant. FR152G, FR152GH, and 1N5392GHB0G are also REACH unaffected.

Q: What is the significance of the DO-15 and DO-204AC package designations?

A: DO-15 and DO-204AC are equivalent package designations for the same axial through-hole diode package. All substitute parts are compatible with existing FR152-TP board layouts and mounting requirements.

Q: Which substitute part offers the best reverse leakage performance?

A: PG151R_R2_00001 offers the lowest reverse leakage at 1 µA @ 100 V, compared to 5 µA @ 100 V for the FR152-TP and most other substitutes.
