RSFAL RTG Equivalent & Substitute Parts

Part Overview

The RSFAL RTG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 50 V DC reverse voltage and 500 mA average rectified current. This component is classified as a fast recovery diode with a reverse recovery time of 150 ns, suitable for surface mount applications in the DO-219AB package configuration. The part is currently in Active product status and is RoHS3 compliant.

Substitute parts are necessary when the RSFAL RTG packaging format (bulk or specific tape configuration) is unavailable, when alternative product statuses are acceptable for legacy designs, or when different packaging formats better suit manufacturing requirements while maintaining identical electrical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RSFAL RTG is determined by electrical parameter equivalence and mechanical compatibility. All substitute parts maintain identical specifications across 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
• RoHS Status: ROHS3 Compliant

Substitute parts differ only in packaging format (Tape & Reel or Cut Tape) and product status designation. These differences do not affect electrical performance or functional compatibility in circuit applications.

Engineering Selection Recommendations

RSFAL RTG (Primary Part): Select this part number for new designs requiring active product status. This configuration is recommended for applications where component lifecycle support and ongoing availability are critical. The part is in Active status and suitable for long-term production use.

RSFAL (Tape & Reel Format): This part number provides identical electrical specifications and is available in higher inventory quantities (9885 Pcs). However, it carries a "Not For New Designs" product status designation. This part is suitable for legacy system maintenance, repair operations, or applications where the Tape & Reel packaging format is specifically required and product status restrictions are acceptable.

RSFAL RVG (Cut Tape Format): This part number is in Active product status and provides identical electrical specifications in Cut Tape packaging format. Select this configuration when Cut Tape packaging is preferred for manufacturing processes or when the higher inventory availability (7680 Pcs) of this format is advantageous.

All three part numbers are RoHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity classification. Selection between these parts should be based on packaging format requirements and product status acceptability for the intended application.

Frequently Asked Questions (FAQ)

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

A: Yes. All three part numbers share identical electrical specifications including 50 V reverse voltage rating, 500 mA average rectified current, 1.3 V forward voltage drop at 500 mA, 150 ns reverse recovery time, and identical operating temperature range (-55°C to 150°C). They are functionally interchangeable in circuit applications.

Q: What is the difference between these part numbers?

A: The differences are limited to packaging format and product status. RSFAL RTG is supplied in bulk format with Active status. RSFAL is supplied in Tape & Reel format with Not For New Designs status. RSFAL RVG is supplied in Cut Tape format with Active status. The electrical performance and mechanical compatibility are identical.

Q: Can I use RSFAL (Not For New Designs) in a new product design?

A: Product status is a lifecycle designation provided by the manufacturer. The "Not For New Designs" status indicates the manufacturer does not recommend this part for new designs. For new product development, RSFAL RTG or RSFAL RVG are the appropriate selections, both carrying Active status.

Q: Does packaging format affect circuit performance?

A: No. Packaging format (bulk, Tape & Reel, or Cut Tape) affects only the delivery and handling method. The DO-219AB package and Sub SMA supplier device package are identical across all three part numbers. Circuit performance and PCB mounting are unaffected by the packaging format selected.

Q: Are all three parts RoHS3 compliant?

A: Yes. RSFAL RTG, RSFAL, and RSFAL RVG are all RoHS3 compliant and REACH unaffected. All three parts carry MSL Level 1 (Unlimited) moisture sensitivity classification.

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

A: For high-volume manufacturing, consider RSFAL RVG (Cut Tape format, 7680 Pcs available) or RSFAL (Tape & Reel format, 9885 Pcs available) based on your assembly equipment compatibility. Both formats are optimized for automated pick-and-place operations. Verify your manufacturing equipment specifications for tape format compatibility before final selection.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All three parts use the DO-219AB package with Sub SMA supplier device package configuration. They are mechanically and electrically interchangeable on PCB assemblies. No circuit modifications or PCB layout changes are required when substituting between these part numbers.
