RSFGLHRVG Equivalent & Substitute Parts

Part Overview

The RSFGLHRVG is a general-purpose fast recovery 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 meets automotive-grade qualification standards (AEC-Q101).

Substitute parts become necessary when the primary part number reaches end-of-life status, when specific packaging formats are required for manufacturing processes, or when inventory constraints necessitate alternative sourcing from the same manufacturer's product line. The RSFGLHRVG maintains identical electrical performance across all qualified substitutes listed in this reference.

Engineering Selection Recommendations

RSFGLHRVG (Primary Selection)

The RSFGLHRVG is the recommended selection for new designs and active production. This part maintains Active product status, ensuring long-term availability and manufacturer support. It carries full automotive-grade qualification (AEC-Q101) and ROHS3 compliance, meeting stringent regulatory requirements for automotive and industrial applications.

RSFGL RVG (Preferred Substitute)

The RSFGL RVG serves as the primary substitute when RSFGLHRVG availability is constrained. This part number maintains Active product status and identical electrical specifications. The only distinction is packaging format: RSFGL RVG is supplied in Cut Tape (CT) format, suitable for automated pick-and-place assembly processes. All electrical and thermal characteristics remain unchanged.

RSFGL (Secondary Substitute)

The RSFGL is available as a secondary substitute option with higher inventory levels (15,589 pieces in stock). However, this part carries "Not For New Designs" product status, indicating it is in mature phase of its lifecycle. RSFGL is supplied in Tape & Reel (TR) format. This part number is suitable only for legacy product support, maintenance, or repair applications where design changes are not feasible. For new design initiatives, RSFGLHRVG or RSFGL RVG are the appropriate selections.

All three part numbers share identical electrical performance, thermal operating range, and compliance certifications. Selection between them depends on packaging requirements and product lifecycle status of the target application.

Frequently Asked Questions (FAQ)

Q: Can RSFGL RVG be used as a direct replacement for RSFGLHRVG in production?

A: Yes. RSFGL RVG is electrically and mechanically equivalent to RSFGLHRVG. Both parts are rated for 400 V DC reverse voltage, 500 mA average rectified current, and operate across the identical temperature range (-55°C to 150°C). The only difference is packaging format: RSFGLHRVG uses Tube packaging while RSFGL RVG uses Cut Tape format. Selection depends on assembly equipment compatibility and supply chain requirements.

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

A: RSFGL and RSFGL RVG are electrically identical. Both are rated for 400 V, 500 mA, with 150 ns reverse recovery time. The differences are: (1) RSFGL carries "Not For New Designs" status while RSFGL RVG is Active; (2) RSFGL is supplied in Tape & Reel format while RSFGL RVG is supplied in Cut Tape format. For new designs, RSFGL RVG is the appropriate choice.

Q: Are all three part numbers suitable for automotive applications?

A: All three part numbers (RSFGLHRVG, RSFGL, and RSFGL RVG) carry automotive-grade qualification and AEC-Q101 certification. All are ROHS3 compliant and REACH unaffected. However, RSFGL carries "Not For New Designs" status, making it unsuitable for new automotive platform development. RSFGLHRVG and RSFGL RVG are both appropriate for automotive applications.

Q: What does "Not For New Designs" mean for the RSFGL part number?

A: "Not For New Designs" indicates the part is in mature lifecycle phase. Manufacturer support and long-term availability are not guaranteed. This designation is used for legacy product support only. For new circuit designs, select RSFGLHRVG or RSFGL RVG instead.

Q: Do packaging format differences affect circuit performance?

A: No. Packaging format (Tube, Tape & Reel, or Cut Tape) affects only the supply and assembly process, not electrical performance. All three part numbers deliver identical forward voltage, reverse voltage rating, reverse recovery time, and leakage current characteristics in circuit operation.

Q: Which part number should be selected for high-volume production?

A: For high-volume production, RSFGL RVG is the optimal selection. It maintains Active product status, ensuring long-term availability, and is supplied in Cut Tape format, which is standard for automated assembly lines. RSFGLHRVG is also suitable if Tube packaging is compatible with assembly equipment.

Q: Are there any temperature or voltage derating considerations between these part numbers?

A: No. All three part numbers operate across the identical junction temperature range (-55°C to 150°C) and are rated for the same maximum reverse voltage (400 V) and forward current (500 mA). No derating adjustments are required when substituting between these part numbers.
