Substitute Part Grouping Explanation
Substitute parts for the HS5M R7G are classified into two categories based on electrical and mechanical compatibility:
Parametric Equivalent (Direct Replacement): Parts that match all critical electrical parameters and package specifications. The HS5M V7G from Taiwan Semiconductor Corporation is a parametric equivalent with identical voltage, current, speed, recovery time, and package characteristics. This part differs only in packaging format (Cut Tape & Digi-Reel versus the original specification).
Similar Manufacturer Parts (Functional Substitutes): Parts that satisfy the core application requirements of 1000 V reverse voltage and surface mount DO-214AB (SMC) packaging but may differ in one or more of the following parameters:
- Current rating (3 A versus 5 A)
- Forward voltage drop (Vf)
- Recovery speed classification (Standard Recovery >500ns versus Fast Recovery ≤500ns)
- Reverse recovery time (trr)
- Reverse leakage current
- Operating temperature range
- Manufacturer and product status
Substitution compatibility is determined by whether the substitute part's electrical characteristics remain within acceptable limits for the target application. Parts with lower current ratings (3 A) are suitable only for applications not requiring the full 5 A capability of the original device.

Engineering Selection Recommendations
Direct Replacement (Parametric Equivalent):
The HS5M V7G from Taiwan Semiconductor Corporation is the parametric equivalent to the HS5M R7G. Both parts share identical electrical specifications: 1000 V reverse voltage, 5 A average rectified current, 1.7 V forward voltage drop at 5 A, fast recovery characteristics with 75 ns reverse recovery time, and DO-214AB (SMC) package. The HS5M V7G is available in Cut Tape and Digi-Reel packaging formats and remains discontinued at DiGi Electronics. This part is suitable for direct substitution in all applications where the HS5M R7G was originally specified.
Active Substitute with Matching Current Rating:
The CGRC507-G from Comchip Technology maintains the 1000 V / 5 A electrical specification and DO-214AB (SMC) package. This part differs in forward voltage drop (1.15 V versus 1.7 V at 5 A) and recovery speed classification (Standard Recovery >500ns versus Fast Recovery ≤500ns). The CGRC507-G is currently active and available in Tape & Reel packaging. Selection of this part is appropriate for applications where the lower forward voltage drop is beneficial and standard recovery speed is acceptable.
Active Substitutes with Reduced Current Rating (3 A):
Multiple active alternatives are available with 1000 V reverse voltage and 3 A current rating in DO-214AB (SMC) packaging:
- ER3M-TP (Micro Commercial Co): Fast recovery, 75 ns trr, 1.7 V Vf @ 3A, operating range -50°C to 175°C
- RS3M-13-F (Diodes Incorporated): Fast recovery, 500 ns trr, 1.3 V Vf @ 3A, operating range -65°C to 150°C
- S3M-13-F (Diodes Incorporated): Standard recovery, 1.15 V Vf @ 3A, operating range -65°C to 150°C
- S3M-TP (Micro Commercial Co): Standard recovery, 1.2 V Vf @ 3A, operating range -55°C to 150°C
- S3MHE3_A/H (Vishay): Standard recovery, 1.15 V Vf @ 2.5A, AEC-Q101 automotive qualified, operating range -55°C to 150°C
These 3 A rated parts are suitable only for applications where the maximum current requirement does not exceed 3 A.
Package Variant Substitutes (SMB):
The RS3MB-13-F and S3MB-13-F from Diodes Incorporated provide 1000 V / 3 A specifications in DO-214AA (SMB) package format. These parts require PCB layout modifications due to different package geometry and are suitable only when SMB package compatibility is confirmed.
All substitute parts listed are ROHS3 compliant, MSL Level 1, and REACH unaffected, matching the compliance profile of the original HS5M R7G.
Frequently Asked Questions (FAQ)
Q: Can the HS5M V7G be used as a direct replacement for the HS5M R7G?
A: Yes. The HS5M V7G is a parametric equivalent with identical electrical specifications and DO-214AB (SMC) package. Both parts are discontinued at DiGi Electronics but share the same voltage rating (1000 V), current rating (5 A), forward voltage drop (1.7 V @ 5A), recovery time (75 ns), and operating temperature range (-55°C to 150°C).
Q: What is the difference between the HS5M R7G and CGRC507-G?
A: Both parts are rated for 1000 V / 5 A in DO-214AB (SMC) package. The CGRC507-G has a lower forward voltage drop (1.15 V versus 1.7 V at 5A) and uses standard recovery speed (>500ns) instead of fast recovery (≤500ns). The CGRC507-G is currently active from Comchip Technology.
Q: Can I use a 3 A rated diode in place of the 5 A HS5M R7G?
A: Only if the application's maximum current requirement does not exceed 3 A. Parts such as ER3M-TP, RS3M-13-F, S3M-13-F, S3M-TP, and S3MHE3_A/H are all rated for 3 A maximum. Using a 3 A part in a 5 A application will result in device failure.
Q: What is the difference between fast recovery and standard recovery diodes?
A: Fast recovery diodes have reverse recovery times of 500 nanoseconds or less, while standard recovery diodes exceed 500 nanoseconds. The HS5M R7G features fast recovery (75 ns). Fast recovery diodes are preferred in high-frequency switching applications. Standard recovery diodes are suitable for lower-frequency rectification.
Q: Are SMB package diodes compatible with SMC package PCB layouts?
A: No. SMB (DO-214AA) and SMC (DO-214AB) packages have different physical dimensions and pin configurations. RS3MB-13-F and S3MB-13-F in SMB package require PCB layout modifications and cannot be directly substituted without redesign.
Q: What does AEC-Q101 qualification mean?
A: AEC-Q101 is an automotive industry qualification standard. The S3MHE3_A/H from Vishay carries this qualification, indicating it meets automotive reliability and performance requirements. This part is suitable for automotive applications requiring qualified components.
Q: Do all substitute parts have the same operating temperature range?
A: No. The HS5M R7G operates from -55°C to 150°C. Substitute parts vary: ER3M-TP extends to 175°C, while RS3M-13-F, RS3MB-13-F, S3M-13-F, S3MB-13-F, and S3MHE3_A/H operate to 150°C maximum. S3M-TP operates to 150°C. Verify temperature range compatibility for your application.
Q: What is the significance of forward voltage drop differences?
A: Forward voltage drop (Vf) affects power dissipation and heat generation. Lower Vf values result in less power loss. The CGRC507-G (1.15 V @ 5A) dissipates less power than the HS5M R7G (1.7 V @ 5A). In high-current applications, this difference impacts thermal management requirements.
Q: Are all listed parts RoHS compliant?
A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, matching the environmental compliance of the original HS5M R7G.
