HS1GL RHG Equivalent & Substitute Parts

Part Overview

The HS1GL RHG 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 equivalent electrical performance from different manufacturers or product lines.

Substitute Part Grouping Explanation

Substitution eligibility for the HS1GL RHG is determined by the following critical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 400 V minimum
Current - Average Rectified (Io): 1 A minimum
Package / Case: DO-219AB (Sub SMA)
Mounting Type: Surface Mount
Operating Temperature Range: -55°C to 150°C minimum
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Parametric Equivalent Parts (ES1GL, ES1GL RVG, HS1GL RVG) meet all primary substitution criteria with identical voltage, current, and package specifications. These parts differ only in reverse recovery time (35 ns vs. 50 ns), capacitance values, and packaging format (Cut Tape, Tape & Reel), which do not affect functional equivalence in standard applications.

Similar Parts (S07G-GS08, S07G-GS18) share the same voltage rating and package but have reduced current rating (700 mA vs. 1 A) and different speed classification (Standard Recovery >500ns). These are classified as similar rather than equivalent due to current rating reduction.

Engineering Selection Recommendations

Parametric Equivalent Selection (Preferred):

ES1GL RVG and HS1GL RVG are the primary substitutes for HS1GL RHG. Both maintain identical voltage and current ratings, identical forward voltage characteristics, and identical operating temperature range. ES1GL RVG is supplied in Tape & Reel format with 4,619 units in stock and carries Active product status. HS1GL RVG is also supplied in Tape & Reel format with 18,316 units in stock and carries Active product status. Both are RoHS3 compliant with MSL 1 rating.

ES1GL is available in Cut Tape and Digi-Reel packaging with 95,300 units in stock but carries Not For New Designs product status. This part is suitable for replacement applications only and not recommended for new design implementations.

Similar Part Selection (Current-Limited Applications):

S07G-GS08 and S07G-GS18 from Vishay General Semiconductor are classified as similar parts due to reduced average rectified current (700 mA vs. 1 A) and standard recovery speed classification. These parts are suitable only for applications where the circuit current requirement does not exceed 700 mA. Both parts carry AEC-Q101 automotive qualification and Active product status. S07G-GS08 has 658,490 units in stock; S07G-GS18 has 95,100 units in stock.

Compliance Considerations:

All listed parts are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.10.0080. All parts maintain MSL 1 (unlimited) moisture sensitivity level, eliminating moisture-related handling constraints.

Frequently Asked Questions (FAQ)

Q: Can ES1GL RVG directly replace HS1GL RHG in existing designs?

A: Yes. ES1GL RVG meets all primary electrical parameters: 400 V reverse voltage, 1 A average rectified current, 1.3 V forward voltage at 1 A, and identical operating temperature range (-55°C to 150°C). The reverse recovery time is faster (35 ns vs. 50 ns), which is not a limitation. Both are RoHS3 compliant with MSL 1 rating. The primary difference is packaging format (Tape & Reel vs. Sub SMA cut tape).

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

A: Both parts are parametric equivalents with identical voltage, current, and temperature specifications. HS1GL RVG has a reverse recovery time of 50 ns and capacitance of 15 pF. ES1GL RVG has a reverse recovery time of 35 ns and capacitance of 8 pF. Both are manufactured by Taiwan Semiconductor Corporation and supplied in Tape & Reel format. HS1GL RVG has higher inventory availability (18,316 units vs. 4,619 units).

Q: Can S07G-GS08 or S07G-GS18 be used as substitutes?

A: S07G-GS08 and S07G-GS18 are classified as similar parts, not parametric equivalents. Both have reduced average rectified current (700 mA vs. 1 A) and standard recovery speed classification (>500ns vs. ≤500ns). These parts are suitable only for applications where circuit current does not exceed 700 mA. If the design requires 1 A current capability, these parts are not suitable.

Q: What is the significance of "Not For New Designs" status on ES1GL?

A: ES1GL carries Not For New Designs product status, indicating the manufacturer is phasing out this part number. ES1GL is suitable for replacement and repair of existing equipment but should not be selected for new design implementations. For new designs, select ES1GL RVG or HS1GL RVG, both carrying Active product status.

Q: Are all substitute parts available in the same package format?

A: No. HS1GL RHG is supplied in Sub SMA cut tape format. ES1GL is supplied in Cut Tape and Digi-Reel format. ES1GL RVG and HS1GL RVG are supplied in Tape & Reel format. S07G-GS08 and S07G-GS18 are supplied in Tape & Reel format as DO-219AB (SMF). Verify packaging compatibility with your assembly process before selection.

Q: What are the key electrical differences between Taiwan Semiconductor and Vishay parts?

A: Taiwan Semiconductor parts (HS1GL RHG, ES1GL, ES1GL RVG, HS1GL RVG) maintain 1 A current rating and fast recovery speed (≤500ns). Vishay parts (S07G-GS08, S07G-GS18) have 700 mA current rating and standard recovery speed (>500ns). Forward voltage is lower on Vishay parts (1.1 V vs. 1.3 V at 1 A). Reverse leakage is higher on Vishay parts (10 µA vs. 5 µA). Select based on circuit current requirements and speed performance needs.

Q: Are all parts RoHS3 compliant?

A: Yes. All listed parts (HS1GL RHG, ES1GL, ES1GL RVG, HS1GL RVG, S07G-GS08, S07G-GS18) are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99. All parts have MSL 1 (unlimited) moisture sensitivity level.
