FR203-TP Equivalent & Substitute Parts

Part Overview

The FR203-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 through-hole DO-15 package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The FR203-TP features fast recovery characteristics with a reverse recovery time of 150 ns and operates across a junction temperature range of -55°C to 150°C. ROHS3 compliance and unlimited moisture sensitivity level (MSL 1) support broad application deployment.

Substitute Part Grouping Explanation

Substitution of the FR203-TP is determined by alignment across the following critical parameters: DC reverse voltage rating (200 V), average rectified current capacity, forward voltage characteristics, reverse recovery time (150 ns fast recovery classification), package form factor (DO-15/DO-204AC through-hole axial), and operating temperature range.

The substitute parts are grouped into two categories:

Parametric Equivalents maintain identical or superior electrical performance across all critical ratings. These parts satisfy direct replacement requirements with no circuit redesign.

Similar Substitutes provide functional equivalence with reduced current capacity (1.5 A versus 2 A) while maintaining voltage, recovery speed, and package compatibility. These parts are suitable for applications where the full 2 A rating is not required.

All substitute candidates maintain ROHS3 compliance, fast recovery speed classification (≤500 ns, >200 mA), and through-hole mounting in DO-15 package form.

Engineering Selection Recommendations

Parametric Equivalents (Direct Replacement)

The FR203G (Taiwan Semiconductor Corporation), FR203GT-G (Comchip Technology), and PG202R_R2_00001 (Panjit International Inc.) are parametric equivalents to the FR203-TP. All three parts maintain identical electrical specifications: 200 V reverse voltage, 2 A average rectified current, 1.3 V forward voltage at 2 A, 150 ns reverse recovery time, and -55°C to 150°C operating temperature range. All three are active products with ROHS3 compliance, eliminating obsolescence risk. These parts are suitable for direct substitution in applications requiring the full 2 A current rating.

FR203G and FR203GT-G are functionally identical with differences limited to packaging format (FR203G supplied in cut tape, FR203GT-G in tape & reel) and manufacturer. PG202R_R2_00001 offers superior reverse leakage performance (1 µA versus 5 µA at 200 V), making it preferable for low-leakage applications. PG202R_R2_00001 also provides the highest inventory availability (4667 pcs).

Similar Substitute (Reduced Current Rating)

The PR1503-T (Diodes Incorporated) is a similar substitute with a reduced average rectified current rating of 1.5 A compared to the FR203-TP's 2 A. All other electrical parameters align: 200 V reverse voltage, 150 ns reverse recovery time, and identical package form factor. PR1503-T is an active product with ROHS3 compliance and an extended operating temperature range (-65°C to 150°C). This part is suitable for applications where the circuit design permits operation at 1.5 A or lower current levels.

Frequently Asked Questions (FAQ)

Q: Can PR1503-T replace FR203-TP in all applications?

A: PR1503-T is suitable only for applications where the average rectified current requirement does not exceed 1.5 A. The FR203-TP is rated for 2 A; circuits designed for the full 2 A rating require a parametric equivalent (FR203G, FR203GT-G, or PG202R_R2_00001) rather than PR1503-T.

Q: What is the difference between FR203G and FR203GT-G?

A: FR203G and FR203GT-G are electrically identical parametric equivalents. The primary difference is packaging: FR203G is supplied in cut tape (CT) format, while FR203GT-G is supplied in tape & reel (TR) format. Selection depends on procurement and assembly requirements.

Q: Does PG202R_R2_00001 offer any performance advantage over FR203G or FR203GT-G?

A: PG202R_R2_00001 maintains identical electrical performance for all primary parameters (voltage, current, recovery time, temperature range). The advantage is reduced reverse leakage current (1 µA versus 5 µA at 200 V), which benefits low-leakage circuit designs. PG202R_R2_00001 also offers the highest inventory availability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The FR203-TP and all four substitute parts (PR1503-T, FR203G, FR203GT-G, PG202R_R2_00001) are ROHS3 compliant. All parts carry unlimited moisture sensitivity level (MSL 1).

Q: What is the significance of the 150 ns reverse recovery time?

A: The 150 ns reverse recovery time classifies all parts as fast recovery diodes (≤500 ns, >200 mA). This specification is maintained across all substitute options, ensuring compatibility with circuits designed for fast recovery performance.

Q: Can I use these parts interchangeably in PCB designs?

A: Yes, for parametric equivalents (FR203G, FR203GT-G, PG202R_R2_00001). All maintain identical DO-15 axial through-hole package form factor and electrical specifications. PR1503-T is mechanically compatible but electrically suitable only for 1.5 A or lower current applications.

Q: Why is the FR203-TP classified as obsolete?

A: The FR203-TP is listed as obsolete by the original manufacturer (Micro Commercial Co). Active parametric equivalents from other manufacturers (Taiwan Semiconductor Corporation, Comchip Technology, Panjit International Inc.) provide continued design support and procurement availability.
