HS3D R7G Equivalent & Substitute Parts

Part Overview

The HS3D R7G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 200 V DC reverse voltage and 3 A average rectified current in a surface mount DO-214AB (SMC) package. This part is classified as discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components for ongoing design requirements and production continuity. The diode features fast recovery characteristics with a 50 ns reverse recovery time and operates across a junction temperature range of -55°C to 150°C. Equivalent parts maintain identical electrical specifications, while substitute parts offer compatible performance within the same application category with minor parameter variations.

Engineering Selection Recommendations

Parametric Equivalent (Direct Replacement):

The HS3D-K M6G is the direct parametric equivalent to the HS3D R7G. Both parts are manufactured by Taiwan Semiconductor Corporation and maintain identical electrical specifications across all critical parameters: 200 V reverse voltage, 3 A average rectified current, 1 V forward voltage at 3 A, and 50 ns reverse recovery time. The HS3D-K M6G is currently in active product status with 637 units in stock, providing immediate availability for production requirements. The primary difference is packaging format: HS3D-K M6G is supplied in Tape & Reel (TR) format, whereas the original HS3D R7G was supplied without specified packaging. Both parts are ROHS3 compliant and REACH unaffected.

Primary Substitute Options (Identical Voltage and Current Ratings):

For applications requiring identical 200 V / 3 A specifications with active product status, the following parts are recommended based on compliance and availability:

ES3D-13-F (Diodes Incorporated): Maintains 200 V / 3 A ratings with improved reverse recovery time of 25 ns and lower forward voltage of 0.9 V @ 3 A. ROHS3 compliant with 45,182 units in stock. Operating temperature range matches the original part (-55°C to 150°C).

Higher Current Rating Option:

CGRC503-G (Comchip Technology): Rated for 200 V / 5 A with standard recovery characteristics. Suitable for applications requiring higher current capacity with the same voltage rating. Not recommended as a direct substitute for 3 A applications due to different recovery speed classification.

Frequently Asked Questions (FAQ)

Q: Can the HS3D-K M6G be used as a direct replacement for the HS3D R7G?

A: Yes. The HS3D-K M6G is a parametric equivalent with identical electrical specifications: 200 V reverse voltage, 3 A average rectified current, 1 V forward voltage at 3 A, and 50 ns reverse recovery time. Both parts are manufactured by Taiwan Semiconductor Corporation and are ROHS3 compliant. The primary difference is packaging format (Tape & Reel vs. unspecified original packaging). Mechanical compatibility in the DO-214AB (SMC) package is maintained.

Q: What is the difference between parametric equivalents and similar manufacturers?

A: Parametric equivalents maintain all critical electrical specifications within the same tolerance band as the original part. Similar manufacturers maintain the core voltage and current ratings but may exhibit variations in secondary parameters such as reverse recovery time, forward voltage, or leakage current. All variations remain within acceptable operating ranges for the application category.

Q: Are there any package compatibility issues with the substitute parts?

A: Most substitute parts use the DO-214AB (SMC) package, which is mechanically compatible with the original HS3D R7G. The exception is ES3DB-13-F, which uses the DO-214AA (SMB) package. SMB packages have different footprint dimensions and are not mechanically interchangeable with SMC packages without PCB redesign. Verify package footprint compatibility before selecting this alternative.

Q: Which substitute offers the best forward voltage performance?

A: The MURS320 series (MURS320-13-F, MURS320-E3/57T, MURS320-E3/9AT) offers the lowest forward voltage at 0.875 V @ 3 A, compared to the original specification of 1 V @ 3 A. ES3D-13-F and ESH3DHE3_A/H offer 0.9 V @ 3 A. Lower forward voltage reduces power dissipation in the diode during operation.

Q: Which substitute has the fastest reverse recovery time?

A: ES3D-13-F and MURS320-13-F both offer 25 ns reverse recovery time, compared to the original 50 ns specification. Faster recovery time reduces switching losses and improves efficiency in high-frequency applications. ER3D-TP offers 35 ns recovery time.

Q: Can I use CGRC503-G as a substitute for the HS3D R7G?

A: CGRC503-G is not recommended as a direct substitute. While it maintains the 200 V reverse voltage rating, it is rated for 5 A average rectified current instead of 3 A, and features standard recovery characteristics (>500ns) instead of fast recovery (≤500ns). Use CGRC503-G only in applications specifically requiring higher current capacity and standard recovery speed.

Q: What is the advantage of selecting parts with extended temperature ranges?

A: Parts with extended operating temperature ranges such as MURS320 series (-65°C to 175°C) and ESH3DHE3_A/H (-55°C to 175°C) provide design flexibility for applications operating in extreme thermal environments. Extended ranges do not affect performance in standard temperature applications but provide margin for thermal stress conditions.

Q: Is the ESH3DHE3_A/H suitable for automotive applications?

A: Yes. ESH3DHE3_A/H carries AEC-Q101 automotive qualification and is suitable for automotive-grade applications. It maintains 200 V / 3 A specifications with extended temperature range of -55°C to 175°C and lower reverse leakage current of 5 µA @ 200 V.

Q: What is the inventory status of recommended substitutes?

A: HS3D-K M6G has 637 units in stock. ES3D-13-F has the highest inventory at 45,182 units. ER3D-TP has 16,840 units. MURS320-13-F has 7,630 units. CURC303-G has 4,164 units. All recommended substitutes are in active product status with current availability.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed in this reference are ROHS3 compliant and REACH unaffected, matching the compliance status of the original HS3D R7G. All parts carry EAR99 ECCN classification.
