FR1001-AP Equivalent & Substitute Parts

Part Overview

The FR1001-AP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 50 V DC reverse voltage and 10 A average rectified current in an R-6 axial through-hole package. This part is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing design support and procurement continuity. Substitute parts are selected based on matching or superior electrical performance within the same package configuration and thermal operating range.

Substitute Part Grouping Explanation

Substitute parts for the FR1001-AP are classified into two categories based on electrical parameter alignment:

Direct Equivalent (Category 1): Parts that maintain identical or superior electrical specifications across all critical parameters while remaining in active production status. These parts satisfy 100% functional replacement requirements.

Functional Equivalent (Category 2): Parts that operate within the same voltage and package envelope but with reduced current rating or modified recovery characteristics. These parts require application-level verification of current capacity and switching performance.

Substitution logic is determined by the following parameters:

• Voltage - DC Reverse (Vr) (Max): Must equal or exceed 50 V
• Package / Case: Must be R-6, Axial through-hole configuration
• Operating Temperature Range: Must encompass -55°C to 150°C
• Current - Average Rectified (Io): Must equal or exceed application requirements
• Reverse Recovery Time (trr): Must be compatible with circuit switching frequency

Engineering Selection Recommendations

FR1001GP-AP (Direct Equivalent - Recommended Primary Substitute)

The FR1001GP-AP is the preferred substitute for the obsolete FR1001-AP. This part is manufactured by the same supplier (Micro Commercial Co) and maintains identical electrical specifications across all critical parameters: 50 V reverse voltage, 10 A average rectified current, 1.3 V forward voltage drop at 10 A, and 150 ns reverse recovery time. The FR1001GP-AP is in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. The reverse leakage current is improved to 5 µA at 50 V compared to the original 10 µA specification, representing enhanced device quality. This part provides 100% functional replacement capability.

6A05GHA0G (Functional Equivalent - Application-Dependent Substitute)

The 6A05GHA0G manufactured by Taiwan Semiconductor Corporation operates within the same 50 V voltage envelope and R-6 axial package configuration. This part is suitable for applications where the average rectified current requirement does not exceed 6 A. The 6A05GHA0G exhibits a lower forward voltage drop of 1.1 V at 6 A, resulting in reduced power dissipation in current-limited applications. However, this part employs standard recovery characteristics (>500ns) rather than fast recovery (≤500ns), which may impact performance in high-frequency switching circuits. The 6A05GHA0G carries AEC-Q101 automotive qualification and REACH compliance status. Selection of this part requires confirmation that the application current demand does not exceed 6 A and that standard recovery speed is compatible with circuit switching requirements.

Frequently Asked Questions (FAQ)

Q: Can FR1001GP-AP be used as a direct replacement for FR1001-AP without circuit modification?

A: Yes. The FR1001GP-AP maintains identical electrical specifications for voltage rating, current capacity, forward voltage drop, and reverse recovery time. Both parts are housed in the R-6 axial through-hole package and operate across the same temperature range. No circuit modification is required.

Q: What is the primary difference between FR1001GP-AP and the original FR1001-AP?

A: The FR1001GP-AP is the active production equivalent of the obsolete FR1001-AP. The primary difference is product status: FR1001GP-AP is in active production, ensuring long-term availability. The reverse leakage current specification is improved in the FR1001GP-AP (5 µA versus 10 µA at 50 V), indicating enhanced device quality.

Q: Under what conditions can 6A05GHA0G be substituted for FR1001-AP?

A: The 6A05GHA0G can be substituted when the application average rectified current requirement does not exceed 6 A and when standard recovery speed (>500ns) is compatible with the circuit switching frequency. The 50 V voltage rating and R-6 axial package are identical. Applications requiring the full 10 A capacity or fast recovery characteristics must use FR1001GP-AP.

Q: Does the 6A05GHA0G have automotive qualification?

A: Yes. The 6A05GHA0G carries AEC-Q101 automotive qualification and is suitable for automotive applications within its 6 A current rating.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. Both FR1001GP-AP and 6A05GHA0G are ROHS3 compliant, matching the compliance status of the original FR1001-AP.

Q: What is the moisture sensitivity level for these diodes?

A: All three parts (FR1001-AP, FR1001GP-AP, and 6A05GHA0G) have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: Can these parts be used interchangeably in high-frequency switching applications?

A: FR1001-AP and FR1001GP-AP are interchangeable in high-frequency applications due to identical 150 ns reverse recovery time specifications. The 6A05GHA0G employs standard recovery characteristics and is not suitable for high-frequency switching applications requiring fast recovery performance.
