Substitute Part Grouping Explanation

Substitution of the HS5A R7G is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 50 V minimum
Current - Average Rectified (Io): 5 A minimum
Package / Case: DO-214AB (SMC) surface mount
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
Reverse Recovery Time (trr): ≤ 50 ns preferred
Operating Temperature Range: -55°C to 150°C minimum

Parametric Equivalent Classification: Parts meeting all primary criteria with identical electrical specifications are classified as parametric equivalents. The HS5A in Tape & Reel (TR) packaging is a direct parametric equivalent, differing only in packaging format from the Cut Tape (CT) original.

Similar Part Classification: Parts with reduced current rating (3 A instead of 5 A) or alternative recovery characteristics are classified as similar parts. These may be used in applications where the full 5 A rating is not required, provided circuit design accommodates the lower current specification.

Engineering Selection Recommendations

Direct Replacement (Parametric Equivalent):

The HS5A in Tape & Reel (TR) packaging from Taiwan Semiconductor Corporation is the direct parametric equivalent to HS5A R7G. This part maintains identical electrical specifications and operating characteristics while offering active product status. Selection of this part eliminates design modification requirements and ensures pin-for-pin compatibility.

Alternative with Identical Electrical Specifications:

The HS5A V7G, also from Taiwan Semiconductor Corporation, provides identical electrical performance to the HS5A R7G. However, this part carries discontinued status at DiGi Electronics, limiting its long-term procurement viability.

Active Alternatives with Current Rating Reduction:

For applications where 5 A average rectified current is not required, the following active parts provide equivalent voltage and package specifications with reduced current ratings:

CURC301-G (Comchip Technology): 3 A rating, fast recovery characteristics, identical forward voltage at rated current
ES3A-13-F (Diodes Incorporated): 3 A rating, fast recovery characteristics, superior reverse recovery time (25 ns), lower forward voltage (0.9 V @ 3 A)
RS3A-13-F (Diodes Incorporated): 3 A rating, fast recovery characteristics, extended temperature range (-65°C to 150°C)
RS3A-E3/57T (Vishay General Semiconductor - Diodes Division): 3 A rating, fast recovery characteristics, identical temperature range to original
RS3A-E3/9AT (Vishay General Semiconductor - Diodes Division): 3 A rating, fast recovery characteristics, identical temperature range to original
RS3A-M3/57T (Vishay General Semiconductor - Diodes Division): 3 A rating, fast recovery characteristics, identical temperature range to original

Alternative with Reduced Recovery Performance:

The CGRC501-G (Comchip Technology) maintains the 5 A current rating and 50 V voltage specification in DO-214AB package. However, this part exhibits standard recovery characteristics (>500ns) rather than fast recovery (≤500ns), resulting in higher switching losses in high-frequency applications.

All recommended alternatives carry RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental and regulatory status.

Frequently Asked Questions (FAQ)

Q: Can the HS5A in Tape & Reel packaging directly replace the HS5A R7G Cut Tape version?

A: Yes. The HS5A in Tape & Reel (TR) packaging is a parametric equivalent with identical electrical specifications, voltage rating, current rating, package type (DO-214AB SMC), and operating temperature range. The only difference is the packaging format (reel versus cut tape), which does not affect electrical performance or pin compatibility.

Q: What is the primary limitation when substituting 3 A rated diodes for the 5 A HS5A R7G?

A: The 3 A rated alternatives (CURC301-G, ES3A-13-F, RS3A series) are limited to 3 A average rectified current. These parts are suitable only for applications where the circuit design requires 3 A or less. Exceeding the rated current of the substitute part will result in thermal stress and potential device failure.

Q: Why does the CGRC501-G have a higher forward voltage specification than the HS5A R7G?

A: The CGRC501-G specifies 1.15 V forward voltage at 5 A compared to 1.0 V for the HS5A R7G. This difference reflects the specific semiconductor process and design of the Comchip device. Higher forward voltage results in increased power dissipation in the diode during conduction.

Q: What is the significance of reverse recovery time (trr) differences among the substitute parts?

A: Reverse recovery time determines the speed at which the diode transitions from forward conduction to reverse blocking. The HS5A R7G specifies 50 ns. Substitute parts with longer trr values (such as RS3A series at 150 ns) exhibit slower switching transitions, resulting in higher switching losses in high-frequency rectification circuits. Parts with shorter trr values (such as ES3A-13-F at 25 ns) provide improved efficiency in fast-switching applications.

Q: Are all substitute parts available in the same DO-214AB (SMC) package?

A: Yes. All substitute parts listed in this reference are available in DO-214AB (SMC) surface mount package, ensuring mechanical and electrical compatibility with the original HS5A R7G footprint and PCB layout.

Q: What compliance certifications should be verified when selecting a substitute part?

A: All recommended substitute parts carry RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original HS5A R7G specifications. REACH status is unaffected for all parts. ECCN classification is EAR99 for all parts, and HTSUS code is 8541.10.0080 for all parts.

Q: Can the HS5A V7G be used as a long-term replacement for the HS5A R7G?

A: The HS5A V7G provides identical electrical specifications and is a direct parametric equivalent. However, this part is discontinued at DiGi Electronics, which limits long-term procurement availability. For new designs or long-term production, the active HS5A in Tape & Reel packaging is the preferred choice.

Q: What is the difference between fast recovery and standard recovery diodes?

A: Fast recovery diodes (≤500ns trr) are designed for high-frequency switching applications and exhibit lower switching losses. Standard recovery diodes (>500ns trr) are suitable for lower-frequency applications and general-purpose rectification. The HS5A R7G is specified as fast recovery, and most active substitutes maintain this characteristic.

Q: How does operating temperature range affect part selection?

A: The HS5A R7G operates from -55°C to 150°C. Most substitute parts maintain this range or extend it. The RS3A-13-F extends the lower limit to -65°C. Verify that the selected substitute part's temperature range encompasses the application's operating environment.
