Substitute Part Grouping Explanation

Substitute parts for the HS1GL R3G are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents share identical or functionally equivalent electrical specifications within the allowed tolerances for this product category:

Voltage - DC Reverse (Vr) (Max): 400 V
Current - Average Rectified (Io): 1 A
Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1 A
Package / Case: DO-219AB
Mounting Type: Surface Mount
Operating Temperature - Junction: -55°C to 150°C

Parametric equivalents may exhibit variations in reverse recovery time (trr) and junction capacitance within acceptable ranges for fast recovery rectifier applications. These variations do not affect functional compatibility in standard general-purpose rectification circuits.

Similar Parts maintain the same package and voltage rating but operate at reduced current ratings (700 mA versus 1 A). These parts are suitable for applications where the full 1 A current capacity is not required and represent a derating scenario.

Engineering Selection Recommendations

Parametric Equivalent Selection (ES1GL RVG and HS1GL RVG)

ES1GL RVG and HS1GL RVG are direct parametric equivalents to HS1GL R3G with active product status. Both parts maintain identical voltage and current ratings, forward voltage characteristics, and operating temperature range. ES1GL RVG exhibits a faster reverse recovery time (35 ns versus 50 ns) and lower junction capacitance (8 pF versus 20 pF), resulting in improved switching performance. HS1GL RVG maintains the same reverse recovery time as the primary part with intermediate capacitance (15 pF). Both alternatives are available in Tape & Reel packaging and comply with RoHS3 and REACH requirements.

Parametric Equivalent Selection (ES1GL)

ES1GL is a parametric equivalent available in Cut Tape and Digi-Reel packaging formats. This part carries a "Not For New Designs" product status designation, indicating it is suitable for replacement and maintenance applications but not recommended for new product development. ES1GL shares identical electrical specifications with ES1GL RVG but differs in packaging format.

Similar Part Selection (S07G-GS08 and S07G-GS18)

S07G-GS08 and S07G-GS18 are manufactured by Vishay General Semiconductor and operate at 700 mA average rectified current, representing a 30% current derating from the primary part. Both parts maintain the 400 V voltage rating and DO-219AB package. These parts feature standard recovery characteristics (1.8 µs reverse recovery time) and are qualified to AEC-Q101 automotive standards. Selection of these parts is appropriate only when circuit design specifications permit operation at reduced current capacity.

Frequently Asked Questions (FAQ)

Q: Can ES1GL RVG be used as a direct replacement for HS1GL R3G?

A: Yes. ES1GL RVG is a parametric equivalent with identical voltage (400 V), current (1 A), and forward voltage (1.3 V @ 1 A) specifications. Both parts are packaged in DO-219AB surface mount configuration with identical operating temperature range (-55°C to 150°C). ES1GL RVG exhibits faster reverse recovery time (35 ns versus 50 ns) and lower junction capacitance (8 pF versus 20 pF), which improves switching performance in fast recovery applications.

Q: What is the difference between HS1GL RVG and ES1GL RVG?

A: Both parts are parametric equivalents with identical voltage, current, and forward voltage ratings. The primary differences are: HS1GL RVG maintains the same reverse recovery time as HS1GL R3G (50 ns), while ES1GL RVG operates at 35 ns. HS1GL RVG exhibits higher junction capacitance (15 pF) compared to ES1GL RVG (8 pF). Both parts are in active product status and available in Tape & Reel packaging.

Q: Why is ES1GL marked as "Not For New Designs"?

A: ES1GL carries a "Not For New Designs" product status, indicating the manufacturer is transitioning this part number. ES1GL remains available for replacement and maintenance of existing applications. For new product development, ES1GL RVG or HS1GL RVG are recommended alternatives with active product status.

Q: Can S07G-GS08 or S07G-GS18 replace HS1GL R3G?

A: S07G-GS08 and S07G-GS18 are similar parts with reduced current capacity (700 mA versus 1 A). These parts maintain the 400 V voltage rating and DO-219AB package but are suitable only for applications where the full 1 A current is not required. These parts feature standard recovery characteristics (1.8 µs) rather than fast recovery, and are qualified to AEC-Q101 automotive standards.

Q: What packaging formats are available for equivalent parts?

A: HS1GL R3G is supplied in Tape & Reel (TR) format. Equivalent parts are available in multiple packaging formats: ES1GL RVG and HS1GL RVG are supplied in Tape & Reel (TR); ES1GL is available in Cut Tape (CT) and Digi-Reel® formats. Packaging format selection depends on manufacturing process requirements and equipment compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (ES1GL, ES1GL RVG, HS1GL RVG, S07G-GS08, and S07G-GS18) are RoHS3 compliant and REACH unaffected, matching the compliance status of HS1GL R3G.

Q: What is the significance of reverse recovery time differences?

A: Reverse recovery time (trr) affects switching speed and electromagnetic interference characteristics. HS1GL R3G operates at 50 ns, while ES1GL and ES1GL RVG operate at 35 ns. Faster recovery times reduce switching losses and EMI in high-frequency applications. S07G-GS08 and S07G-GS18 operate at 1.8 µs, suitable for standard recovery applications. Selection depends on circuit switching frequency requirements.

Q: What is the significance of junction capacitance differences?

A: Junction capacitance affects high-frequency performance and switching characteristics. HS1GL R3G exhibits 20 pF capacitance, while ES1GL and ES1GL RVG exhibit 8 pF, and S07G-GS08 and S07G-GS18 exhibit 4 pF. Lower capacitance values reduce switching losses and improve performance in high-frequency rectification circuits.
