HS1GL MHG Equivalent & Substitute Parts

Part Overview

The HS1GL MHG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 400 V DC reverse voltage and 1 A average rectified current in a Sub SMA surface mount package (DO-219AB). This component is classified as Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are necessary when the primary part number becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design revisions call for components from different manufacturers while maintaining electrical and mechanical compatibility within specified parameters.

Key Parameters

Substitute Part Grouping Explanation

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

Parametric Equivalents maintain identical or superior electrical performance across all critical parameters: 400 V reverse voltage rating, 1 A average rectified current, 1.3 V forward voltage drop at 1 A, fast recovery speed (≤500 ns for currents >200 mA), and DO-219AB package format. These parts differ only in packaging configuration (Cut Tape vs. Tape & Reel) or minor variations in reverse recovery time and junction capacitance that do not affect circuit functionality.

Similar Parts share the same package format (DO-219AB) and 400 V reverse voltage rating but operate at reduced current ratings (700 mA vs. 1 A) and employ standard recovery speed characteristics (>500 ns). These parts are suitable for applications where the full 1 A current rating is not required.

The key parameters determining substitution eligibility are:

• Voltage - DC Reverse (Vr) (Max): 400 V minimum
• Package / Case: DO-219AB
• Mounting Type: Surface Mount
• Current - Average Rectified (Io): 1 A for parametric equivalents; 700 mA for similar parts

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

ES1GL RVG and HS1GL RVG are direct functional replacements for HS1GL MHG. Both maintain the 400 V / 1 A electrical specification and DO-219AB package format. ES1GL RVG offers improved reverse recovery time (35 ns vs. 50 ns) and reduced junction capacitance (8 pF vs. 20 pF), resulting in faster switching characteristics. HS1GL RVG maintains the original reverse recovery time specification while providing intermediate capacitance (15 pF). Both substitute parts carry Active product status and full RoHS3 compliance.

ES1GL is electrically equivalent but carries Not For New Designs product status, limiting its use to legacy system maintenance or existing inventory applications.

For Current-Limited Applications (Similar Parts):

S07G-GS08 and S07G-GS18 from Vishay General Semiconductor are suitable substitutes for applications where the circuit current requirement does not exceed 700 mA. Both parts maintain 400 V reverse voltage rating and DO-219AB package compatibility. These parts employ standard recovery speed technology (1.8 µs) and carry AEC-Q101 automotive qualification. Reverse leakage current is specified at 10 µA, which is acceptable for general-purpose rectification in non-critical applications.

Compliance and Certification:

All substitute parts listed maintain RoHS3 compliance, MSL 1 (unlimited moisture sensitivity), and REACH unaffected status, matching the regulatory profile of the primary part. ECCN and HTSUS classifications remain consistent across all alternatives.

Frequently Asked Questions (FAQ)

Q: Can ES1GL RVG be used as a direct replacement for HS1GL MHG in all applications?

A: Yes. ES1GL RVG maintains identical voltage (400 V) and current (1 A) ratings, forward voltage drop (1.3 V @ 1 A), and package format (DO-219AB). The improved reverse recovery time (35 ns vs. 50 ns) and reduced capacitance (8 pF vs. 20 pF) represent performance enhancements that do not compromise compatibility. Both parts are Active status with full RoHS3 compliance.

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

A: Both parts share identical electrical ratings (400 V, 1 A, 1.3 V forward drop) and package format. HS1GL RVG maintains the original 50 ns reverse recovery time with 15 pF capacitance, while ES1GL RVG offers faster recovery (35 ns) with lower capacitance (8 pF). Selection depends on circuit switching speed requirements and capacitive load sensitivity.

Q: Can S07G-GS08 replace HS1GL MHG in a 1 A application?

A: No. S07G-GS08 is rated for 700 mA average rectified current, which is insufficient for applications requiring the full 1 A specification of HS1GL MHG. Use S07G-GS08 only in circuits where maximum current demand does not exceed 700 mA. Additionally, S07G-GS08 employs standard recovery speed (1.8 µs) compared to the fast recovery (50 ns) of HS1GL MHG, affecting switching performance in high-frequency applications.

Q: What packaging formats are available for equivalent parts?

A: HS1GL MHG is supplied in standard packaging format. Equivalent parts are available in Cut Tape (CT) & Digi-Reel® format (ES1GL) and Tape & Reel (TR) format (ES1GL RVG, HS1GL RVG). Tape & Reel packaging is standard for automated assembly processes. Cut Tape format is suitable for manual assembly or lower-volume production. All formats use the same DO-219AB package case.

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

A: ES1GL carries Not For New Designs product status, indicating that the manufacturer recommends using alternative part numbers for new circuit designs. This status does not affect electrical compatibility but signals potential long-term availability concerns. For new designs, select ES1GL RVG or HS1GL RVG, both carrying Active status.

Q: Are the Vishay S07G parts suitable for automotive applications?

A: Yes. S07G-GS08 and S07G-GS18 carry AEC-Q101 automotive qualification and Grade designation, making them suitable for automotive-grade applications. However, their 700 mA current rating and standard recovery speed characteristics limit their use to lower-current automotive circuits compared to the 1 A fast-recovery HS1GL MHG.

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

A: Reverse recovery time (trr) determines how quickly the diode transitions from conducting to blocking state. HS1GL MHG and HS1GL RVG specify 50 ns, while ES1GL RVG specifies 35 ns. Faster recovery (lower trr) reduces switching losses and improves efficiency in high-frequency applications. S07G parts specify 1.8 µs, suitable only for low-frequency rectification. Selection depends on circuit operating frequency and efficiency requirements.

Q: Do all substitute parts meet the same environmental and compliance standards?

A: Yes. All listed substitute parts maintain RoHS3 compliance, MSL 1 (unlimited moisture sensitivity), REACH unaffected status, and identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications. Operating temperature range is -55°C to 150°C for all parts, matching the primary HS1GL MHG specification.
