RSFGL RTG Equivalent & Substitute Parts

Part Overview

The RSFGL RTG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 400 V DC reverse voltage and 500 mA average rectified current in a Sub SMA surface mount package. 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 necessitate component sourcing from multiple suppliers. The RSFGL RTG maintains parametric equivalence across several part variants and similar alternatives from other manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RSFGL RTG is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 400 V
• Current - Average Rectified (Io): 500 mA minimum
• Package / Case: DO-219AB
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C minimum range

Packaging Format Variants: The RSFGL RTG is available in multiple packaging formats (Tape & Reel, Cut Tape) that maintain identical electrical specifications. These variants are direct substitutes when packaging requirements differ for automated assembly processes.

Similar Alternatives: Parts with higher current ratings (700 mA) and identical voltage specifications are classified as similar alternatives. These components operate within the same voltage envelope and package form factor but provide increased current capacity. Substitution to higher-rated alternatives is permissible when circuit design allows for the increased current capability.

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalents (Direct Substitutes):

RSFGL and RSFGL RVG are parametric equivalents of RSFGL RTG with identical electrical specifications. Selection between these variants is determined by packaging format requirements:

• RSFGL RVG (Cut Tape format) is recommended for active designs due to Active product status
• RSFGL (Tape & Reel format) is marked as Not For New Designs and should be avoided in new product development

Similar Alternatives (Higher Current Rating):

S07G-GS08 and S07G-GS18 from Vishay General Semiconductor are similar alternatives with 400 V voltage rating and 700 mA current capacity. These components are suitable for substitution when circuit requirements permit the increased current rating. Both alternatives maintain DO-219AB package compatibility and are Active product status. S07G-GS08 and S07G-GS18 carry AEC-Q101 automotive qualification.

Compliance Considerations:

All listed parts maintain RoHS3 compliance and REACH Unaffected status. Moisture sensitivity level is MSL 1 (Unlimited) across all variants, indicating no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can RSFGL RVG be used as a direct replacement for RSFGL RTG?

A: Yes. RSFGL RVG is a parametric equivalent with identical electrical specifications (400 V, 500 mA, 150 ns recovery time). The difference is packaging format: RSFGL RVG is supplied in Cut Tape format while RSFGL RTG uses standard packaging. Both maintain DO-219AB package form factor and surface mount compatibility.

Q: What is the difference between RSFGL and RSFGL RVG?

A: Both parts are parametrically identical with 400 V reverse voltage and 500 mA current rating. The distinction is packaging format: RSFGL is supplied in Tape & Reel format and carries Not For New Designs status, while RSFGL RVG is supplied in Cut Tape format with Active product status. For new designs, RSFGL RVG is the preferred variant.

Q: Can S07G-GS08 or S07G-GS18 replace RSFGL RTG?

A: S07G-GS08 and S07G-GS18 are similar alternatives with identical 400 V voltage rating and DO-219AB package compatibility. These Vishay components have 700 mA current capacity compared to 500 mA for RSFGL RTG. Substitution is permissible when circuit design accommodates the higher current rating. Both alternatives are Active product status with AEC-Q101 automotive qualification.

Q: What are the key electrical differences between RSFGL RTG and Vishay S07G alternatives?

A: The primary differences are current rating (500 mA vs. 700 mA), forward voltage (1.3 V @ 500 mA vs. 1.1 V @ 1 A), and reverse recovery time (150 ns vs. 1800 ns). The Vishay parts are standard recovery diodes while RSFGL RTG is fast recovery. Voltage rating and package form factor are identical at 400 V and DO-219AB respectively.

Q: Are all listed parts RoHS3 compliant?

A: Yes. All parts listed—RSFGL RTG, RSFGL, RSFGL RVG, S07G-GS08, and S07G-GS18—are RoHS3 compliant with REACH Unaffected status.

Q: What packaging formats are available for RSFGL equivalents?

A: RSFGL equivalents are available in two packaging formats: Tape & Reel (TR) for RSFGL variant and Cut Tape (CT) for RSFGL RVG variant. Both maintain identical DO-219AB package form factor and surface mount mounting type. Selection depends on assembly process requirements.

Q: Should RSFGL (Not For New Designs) be used in new product development?

A: No. RSFGL carries Not For New Designs product status. For new designs, use RSFGL RVG (Active status, Cut Tape format) or RSFGL RTG (Active status) as these maintain full parametric equivalence with current product support.
