RSFALHRVG Equivalent & Substitute Parts

Part Overview

The RSFALHRVG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, designed for surface mount applications in the Sub SMA package format. This component operates at 50 V DC reverse voltage with a 500 mA average rectified current rating and features fast recovery characteristics with a 150 ns reverse recovery time.

The RSFALHRVG maintains Active product status and carries AEC-Q101 automotive qualification. Alternative part numbers within this product family are available due to packaging format variations and inventory distribution across different supplier configurations. Substitute parts maintain identical electrical specifications while differing in packaging presentation (Tape & Reel, Cut Tape) and product lifecycle status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSFALHRVG is determined by electrical parameter equivalence and mechanical compatibility. All substitute parts must maintain the following critical parameters:

• Voltage - DC Reverse (Vr) (Max): 50 V
• Current - Average Rectified (Io): 500 mA
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 500 mA
• Reverse Recovery Time (trr): 150 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 50 V
• Capacitance @ Vr, F: 4 pF @ 4V, 1MHz
• Package / Case: DO-219AB
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C

The identified substitute parts RSFAL and RSFAL RVG satisfy all electrical and mechanical requirements. Differences exist only in packaging presentation format (Tape & Reel versus Cut Tape) and product lifecycle designation, which do not affect functional performance in circuit applications.

Engineering Selection Recommendations

RSFALHRVG (Primary Part)

The RSFALHRVG is the recommended selection for new designs. This part maintains Active product status, indicating ongoing manufacturer support and availability. It carries AEC-Q101 automotive qualification and ROHS3 compliance. The component is available in tube packaging format with 741 pieces in current inventory.

RSFAL RVG (Preferred Substitute)

The RSFAL RVG is the preferred substitute option. This part number maintains Active product status identical to the primary part and carries all equivalent certifications and compliance designations. It differs only in packaging presentation, supplied in Cut Tape format. Inventory availability is 7,680 pieces. This part is suitable for direct substitution in production environments where Cut Tape packaging is compatible with assembly processes.

RSFAL (Secondary Substitute)

The RSFAL part number is available as a secondary substitute option. This part carries Not For New Designs status, indicating it is maintained for legacy support and existing production lines only. It is supplied in Tape & Reel packaging format with 9,885 pieces in inventory. Use of this part number is restricted to applications where existing designs or production commitments require continuity with previously qualified components.

Frequently Asked Questions (FAQ)

Q: Are RSFALHRVG, RSFAL, and RSFAL RVG electrically identical?

A: Yes. All three part numbers are electrically equivalent. They share identical specifications for reverse voltage (50 V), average rectified current (500 mA), forward voltage (1.3 V @ 500 mA), reverse recovery time (150 ns), reverse leakage current (5 µA @ 50 V), and junction temperature range (-55°C to 150°C).

Q: What is the difference between these part numbers?

A: The differences are limited to packaging format and product lifecycle status. RSFALHRVG is supplied in tube packaging, RSFAL in Tape & Reel format, and RSFAL RVG in Cut Tape format. RSFALHRVG and RSFAL RVG maintain Active status, while RSFAL is designated Not For New Designs.

Q: Can I use RSFAL in a new design?

A: RSFAL carries Not For New Designs status. For new designs, use either RSFALHRVG or RSFAL RVG, both of which maintain Active product status and equivalent electrical specifications.

Q: Are there any thermal or electrical performance differences between the packaging formats?

A: No. The electrical performance and thermal characteristics are identical across all three part numbers. Packaging format differences do not affect component performance in circuit operation.

Q: Do all three parts have the same compliance certifications?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry AEC-Q101 automotive qualification. Moisture sensitivity level is 1 (Unlimited) for all variants.

Q: Which part should I select for high-volume production?

A: For high-volume production, select based on your assembly equipment compatibility. If your production line uses Tape & Reel feeders, RSFAL is available with 9,885 pieces in inventory. If your line uses Cut Tape, RSFAL RVG is available with 7,680 pieces. Both maintain equivalent electrical performance.

Q: Can I mix these part numbers in the same production batch?

A: Yes. Since all three part numbers are electrically and mechanically equivalent, they can be used interchangeably in the same circuit application and production batch without functional impact.
