RS1GL Equivalent & Substitute Parts

Part Overview

The RS1GL is a general-purpose fast recovery rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 400 V DC reverse voltage and 800 mA average rectified current in a Sub SMA surface mount package (DO-219AB). The device is classified as Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical performance can be achieved within the allowed parameter ranges for this diode category, accounting for variations in current rating, package form factor, and recovery characteristics while maintaining voltage and thermal specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RS1GL are classified into three categories based on electrical and mechanical compatibility:

Manufacturer Recommended Substitute (MFR Recommended): RS1GLW meets the 400 V reverse voltage requirement and exceeds the current rating at 1 A. The package differs (SOD-123W vs. Sub SMA), requiring PCB layout modification. Forward voltage and recovery time specifications are identical. Operating temperature range extends to 175°C.

Parametric Equivalents: RS1GL R3G maintains identical electrical specifications and package form (DO-219AB Sub SMA), with matching voltage, current, forward voltage, and recovery characteristics. This represents a direct parametric equivalent with different manufacturing revision.

Similar Alternatives: Parts including RS1004FL_R1_00001 (Panjit), RS1GL (SMC Diode Solutions), S07G-GS08, and S07G-GS18 (Vishay) share the 400 V voltage rating but vary in current capacity, recovery speed, and package configuration. These alternatives require evaluation against specific circuit requirements.

Substitution logic is based on:

• Voltage - DC Reverse (Vr) rating must equal or exceed 400 V
• Current - Average Rectified (Io) must meet or exceed circuit demand
• Reverse Recovery Time (trr) must support circuit switching frequency
• Package compatibility with PCB layout constraints
• Operating temperature range suitability

Engineering Selection Recommendations

RS1GLW (MFR Recommended Substitute): This part is the manufacturer-recommended alternative, offering increased current capacity (1 A vs. 800 mA) with identical voltage and recovery specifications. The extended operating temperature range to 175°C provides additional thermal margin. Package change from Sub SMA to SOD-123W requires PCB redesign. Selection is appropriate when higher current headroom is required and layout modification is feasible. RoHS3 compliance and REACH Unaffected status match the main part.

RS1GL R3G (Parametric Equivalent): This revision variant maintains complete electrical and package equivalence to the RS1GL, serving as a direct replacement without layout modification. Identical specifications across voltage, current, recovery time, and temperature range. Selection is appropriate for inventory substitution or when sourcing the primary part number becomes unavailable. RoHS3 compliance and REACH Unaffected status are maintained.

RS1004FL_R1_00001 (Panjit Alternative): This part provides 1 A current capacity with improved reverse leakage (1 µA vs. 5 µA) and slightly lower capacitance (9 pF vs. 10 pF). Package change to SOD-123FL requires PCB layout modification. Recovery time matches at 150 ns. Selection is appropriate when lower leakage current is a design requirement and package change is acceptable. RoHS3 compliance and REACH Unaffected status are maintained.

S07G-GS08 and S07G-GS18 (Vishay Alternatives): These parts maintain 400 V voltage rating and DO-219AB package compatibility but operate with standard recovery characteristics (1.8 µs vs. 150 ns fast recovery). Current rating is reduced to 700 mA. Both parts carry AEC-Q101 automotive qualification. Selection is appropriate only when fast recovery performance is not required and lower current capacity is acceptable. RoHS3 compliance and REACH Unaffected status are maintained.

Frequently Asked Questions (FAQ)

Q: Can RS1GLW replace RS1GL in all applications?

A: RS1GLW is electrically compatible with identical voltage and recovery specifications. The primary consideration is package change from Sub SMA (DO-219AB) to SOD-123W, which requires PCB layout modification. Current capacity increase (1 A vs. 800 mA) is beneficial for most applications. Extended temperature range to 175°C provides additional margin.

Q: What is the difference between RS1GL and RS1GL R3G?

A: RS1GL R3G is a parametric equivalent with identical electrical specifications and package form. The designation indicates a different manufacturing revision. Both parts are interchangeable without layout modification and serve as direct substitutes.

Q: Why do S07G-GS08 and S07G-GS18 have longer recovery times?

A: These Vishay parts employ standard recovery technology (1.8 µs) rather than fast recovery (150 ns). This characteristic difference affects switching frequency capability and thermal performance. Selection of these alternatives is appropriate only when circuit design does not require fast recovery performance.

Q: Can I use RS1004FL_R1_00001 as a substitute?

A: RS1004FL_R1_00001 provides equivalent voltage and recovery specifications with improved reverse leakage characteristics. Package change from Sub SMA to SOD-123FL requires PCB redesign. Current capacity increase to 1 A is beneficial. Selection requires confirmation that layout modification is feasible.

Q: What package compatibility issues should I consider?

A: The RS1GL uses DO-219AB (Sub SMA) package. RS1GLW uses SOD-123W, RS1004FL_R1_00001 uses SOD-123F, and S07G-GS08/S07G-GS18 use DO-219AB (SMF). Package changes require PCB footprint modification. DO-219AB variants (Sub SMA vs. SMF) may have dimensional differences requiring verification against specific PCB design.

Q: Are all substitute parts RoHS3 compliant?

A: All listed substitute parts are RoHS3 compliant. REACH status is Unaffected for all parts except RS1GL (SMC Diode Solutions), which is REACH Affected. Compliance verification is required for applications subject to REACH regulations.

Q: What is the significance of reverse leakage current differences?

A: Reverse leakage current affects power dissipation and circuit performance at high temperatures. RS1GL and RS1GLW specify 5 µA at 400 V. RS1004FL_R1_00001 specifies 1 µA at 400 V, providing lower leakage. S07G-GS08 and S07G-GS18 specify 10 µA, representing higher leakage. Selection depends on circuit sensitivity to leakage current.

Q: Can I use these parts interchangeably in automotive applications?

A: S07G-GS08 and S07G-GS18 carry AEC-Q101 automotive qualification. Other parts do not list automotive qualification. Application in automotive circuits requires verification against specific qualification requirements and design standards.
