Substitute Part Grouping Explanation

Substitution of the RS1GL rectifier diode is determined by electrical parameter compatibility and physical package constraints. The primary substitution criteria are:

Electrical Parameters:

Voltage - DC Reverse (Vr) rating must equal or exceed 400V
Current - Average Rectified (Io) must equal or exceed 800mA
Speed classification must support fast recovery operation (≤ 500ns for currents > 200mA)
Reverse Recovery Time (trr) must equal or be less than 150ns
Reverse Leakage Current must not exceed 5µA @ 400V
Operating temperature range must encompass -55°C to 150°C

Physical Parameters:

Mounting type must be Surface Mount
Package / Case must be compatible with DO-219AB or equivalent Sub SMA footprint

Compliance Parameters:

RoHS3 compliance required
Moisture Sensitivity Level 1 (Unlimited) required

Parts are grouped into two categories: Parametric Equivalents (identical electrical specifications with potential packaging variations) and Similar Parts (matching voltage and temperature ratings with acceptable deviations in current capacity or recovery characteristics).

Engineering Selection Recommendations

Parametric Equivalent - RS1GL (SMC Diode Solutions): This part is a parametric equivalent with identical electrical specifications to the main RS1GL. The primary difference is packaging format (SOD-123FL versus Sub SMA) and supplier. This substitute is suitable for applications where the SOD-123F footprint is acceptable. All electrical parameters, compliance certifications (ROHS3), and operating temperature range are identical. Higher current rating (1A versus 800mA) provides additional design margin.

Parametric Equivalent - RS1GL R3G (Taiwan Semiconductor Corporation): This part is identical to the main RS1GL in all electrical and thermal specifications. The distinction is packaging format (Tape & Reel versus Cut Tape). This substitute is appropriate for high-volume production environments requiring reel packaging. All compliance requirements and electrical parameters are maintained.

Similar Part - S07G-GS08 and S07G-GS18 (Vishay General Semiconductor): These parts share the same 400V reverse voltage rating and DO-219AB package footprint as the main RS1GL. However, they differ in recovery speed classification (Standard Recovery >500ns versus Fast Recovery ≤500ns) and reverse recovery time (1.8µs versus 150ns). Current rating is lower at 700mA. These parts are suitable for applications where fast recovery performance is not a critical requirement and where the lower current capacity is acceptable. Both parts carry AEC-Q101 automotive qualification and are ROHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can the RS1GL (SMC Diode Solutions) substitute for the main RS1GL in all applications?

A: The SMC Diode Solutions RS1GL is electrically equivalent with identical voltage, current, and recovery specifications. The primary consideration is package compatibility. The SMC part uses SOD-123F packaging while the main part uses Sub SMA (DO-219AB). PCB layout and footprint design must accommodate the different package geometry. Electrical performance is interchangeable.

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

A: The RS1GL R3G is electrically and thermally identical to the main RS1GL. The only difference is the packaging format: RS1GL R3G is supplied in Tape & Reel format while the main part is supplied in Cut Tape format. Both use the same DO-219AB package footprint. Selection depends on production volume and handling requirements.

Q: Are the Vishay S07G-GS08 and S07G-GS18 suitable replacements for the RS1GL?

A: The Vishay parts are similar but not parametric equivalents. They maintain the 400V voltage rating and DO-219AB package compatibility. However, they use Standard Recovery technology (1.8µs recovery time) instead of Fast Recovery (150ns), and have a lower current rating of 700mA instead of 800mA. These parts are suitable only for applications where fast recovery performance is not required and where the lower current capacity meets design requirements.

Q: What packaging options are available for the RS1GL?

A: The main RS1GL is available in Sub SMA (DO-219AB) with Cut Tape packaging. The RS1GL R3G variant offers the same Sub SMA package in Tape & Reel format. The SMC Diode Solutions RS1GL is available in SOD-123F package with Cut Tape and Digi-Reel options. Package selection depends on PCB footprint design and production volume requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The main RS1GL, RS1GL R3G, RS1GL (SMC), S07G-GS08, and S07G-GS18 are all ROHS3 compliant. All parts also have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.

Q: What is the difference in reverse recovery time between the main RS1GL and the Vishay S07G parts?

A: The main RS1GL has a reverse recovery time of 150 nanoseconds, classified as Fast Recovery. The Vishay S07G-GS08 and S07G-GS18 have a reverse recovery time of 1.8 microseconds, classified as Standard Recovery. This 12-fold difference affects switching speed and is critical in high-frequency applications. Fast recovery diodes are required for applications operating above approximately 100kHz.

Q: Can the lower current-rated S07G parts be used in place of the 800mA RS1GL?

A: The S07G-GS08 and S07G-GS18 are rated for 700mA average rectified current, which is 100mA below the RS1GL specification. These parts can be used only if the actual circuit current requirement does not exceed 700mA and includes adequate design margin. Using a lower-rated component reduces safety margin and is not recommended for applications designed to the full 800mA specification.
