FR101GP-TP Equivalent & Substitute Parts

Part Overview

The FR101GP-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 50 V DC reverse voltage and 1 A average rectified current in a through-hole DO-41 package. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. Identifying equivalent and substitute parts is necessary for ongoing maintenance, repair, and legacy system support where the original part is no longer readily available or when design flexibility permits component selection from active product lines.

Substitute Part Grouping Explanation

Substitution of the FR101GP-TP is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

Voltage - DC Reverse (Vr) (Max): 50 V
Current - Average Rectified (Io): 1 A
Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1 A
Reverse Recovery Time (trr): 150 ns
Current - Reverse Leakage @ Vr: 5 µA @ 50 V
Mounting Type: Through Hole
Package / Case: DO-204AL, DO-41, Axial
Operating Temperature - Junction: -55°C to 150°C
Technology: Standard
RoHS Status: ROHS3 Compliant

All substitute parts listed meet these electrical and mechanical specifications. Variations in capacitance at Vr and reverse leakage current within the specified range do not preclude substitution, as these parameters remain within acceptable operating margins for general-purpose rectification applications.

Engineering Selection Recommendations

FR101G (Taiwan Semiconductor Corporation)

The FR101G is an active product offering parametric equivalence to the FR101GP-TP across all critical electrical specifications. This part is suitable for direct substitution in applications requiring 50 V, 1 A general-purpose rectification. The FR101G maintains ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with modern manufacturing and environmental standards.

FR101G R1G (Taiwan Semiconductor Corporation)

The FR101G R1G provides identical electrical performance to the FR101G with active product status. This variant is available in higher inventory quantities and offers the same parametric equivalence for legacy system support and repair applications.

FR101T-G (Comchip Technology)

The FR101T-G is an active product with full parametric equivalence to the FR101GP-TP. This part is packaged in tape and reel format and maintains all required electrical characteristics. The slightly elevated capacitance specification (25 pF versus 15 pF) remains within acceptable operating parameters for standard rectification circuits.

PG100R_R2_00001 (Panjit International Inc.)

The PG100R_R2_00001 is an active product offering parametric equivalence with an improved reverse leakage current specification (1 µA versus 5 µA at 50 V). This part is suitable for applications where lower leakage current provides operational advantage. Full ROHS3 and REACH compliance is maintained.

All substitute parts are active products, eliminating obsolescence risk associated with the FR101GP-TP's "Not For New Designs" status.

Frequently Asked Questions (FAQ)

Q: Can the FR101G directly replace the FR101GP-TP in existing circuit boards?

A: Yes. The FR101G meets all electrical and mechanical specifications of the FR101GP-TP. Both parts are rated for 50 V reverse voltage, 1 A average rectified current, and feature identical forward voltage characteristics. The through-hole DO-41 package is mechanically compatible.

Q: What is the difference between FR101G and FR101G R1G?

A: Both parts are electrically and mechanically identical. The FR101G R1G is a variant designation from Taiwan Semiconductor Corporation with higher available inventory. Selection between these two is based on supply availability and procurement requirements.

Q: Why does the PG100R_R2_00001 have lower reverse leakage current?

A: The PG100R_R2_00001 specifies 1 µA reverse leakage at 50 V compared to 5 µA for the FR101GP-TP. This represents improved device characteristics from Panjit International Inc. and does not affect substitution eligibility. Lower leakage current may provide operational benefits in high-impedance circuits.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, matching the compliance status of the FR101GP-TP. This ensures compatibility with modern manufacturing processes and environmental regulations.

Q: What is the significance of the FR101GP-TP being "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status and is no longer recommended for new product development. The substitute parts listed—FR101G, FR101G R1G, FR101T-G, and PG100R_R2_00001—are all active products suitable for both legacy system support and new applications.

Q: Can I use the FR101T-G if my circuit has tight capacitance tolerances?

A: The FR101T-G specifies 25 pF capacitance at 4V, 1MHz, compared to 15 pF for the FR101GP-TP. If your circuit design requires the lower capacitance value, select FR101G, FR101G R1G, or PG100R_R2_00001 instead.

Q: Are these parts suitable for high-frequency switching applications?

A: All listed parts feature 150 ns reverse recovery time and fast recovery characteristics (≤500 ns, >200 mA). They are classified as standard technology general-purpose rectifiers and are suitable for standard rectification applications within their rated specifications.

Q: What packaging formats are available for these substitute parts?

A: FR101G and FR101T-G are available in tape and reel (TR) packaging. FR101G R1G packaging format is not specified in available data. PG100R_R2_00001 is available in tape and reel format. All parts feature through-hole mounting in DO-41 or DO-204AL package styles.
