RSFAL RQG Equivalent & Substitute Parts

Part Overview

The RSFAL RQG 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, packaged in the DO-219AB Sub SMA surface mount configuration. The part is currently in Active product status and is RoHS3 compliant.

Substitute parts are necessary when the original RSFAL RQG packaging format (unspecified packaging type) is unavailable or when alternative packaging configurations such as Tape & Reel or Cut Tape are required for manufacturing processes. Substitute parts maintain identical electrical specifications and mechanical compatibility while offering different distribution formats.

Substitute Part Grouping Explanation

Substitute parts for the RSFAL RQG are determined by equivalence in the following critical electrical and mechanical 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
• Operating Temperature - Junction: -55°C to 150°C
• Package / Case: DO-219AB
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All substitute parts listed maintain identical electrical performance and mechanical compatibility. Differences exist only in packaging format (Tape & Reel or Cut Tape) and product status designations.

Engineering Selection Recommendations

RSFAL RQG (Primary Part)

The RSFAL RQG is designated as Active product status and is suitable for new design implementations. This part number should be selected for new applications requiring the general-purpose 50 V, 500 mA rectifier diode in Sub SMA packaging.

RSFAL (Substitute - Tape & Reel Format)

The RSFAL is electrically and mechanically equivalent to the RSFAL RQG but is designated as Not For New Designs. This part is available in Tape & Reel packaging format and contains significantly higher inventory (9885 Pcs). Selection of this part is appropriate only for legacy system maintenance, repair, or when Tape & Reel format is specifically required for automated assembly processes and the Not For New Designs status is acceptable for the application.

RSFAL RVG (Substitute - Cut Tape Format)

The RSFAL RVG is electrically and mechanically equivalent to the RSFAL RQG and maintains Active product status. This part is available in Cut Tape packaging format with 7680 Pcs in inventory. Selection of this part is appropriate when Cut Tape format is required for manual assembly or when Active product status is mandated for new designs.

All three parts are RoHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can RSFAL RQG be directly replaced with RSFAL or RSFAL RVG?

A: Yes. All three parts are electrically and mechanically equivalent. They share identical electrical specifications including voltage rating (50 V), current rating (500 mA), forward voltage drop (1.3 V @ 500 mA), reverse recovery time (150 ns), and operating temperature range (-55°C to 150°C). All are packaged in DO-219AB Sub SMA surface mount configuration. Differences exist only in packaging format (Tape & Reel versus Cut Tape) and product status designation.

Q: What is the difference between RSFAL RQG, RSFAL, and RSFAL RVG?

A: The primary differences are packaging format and product status. RSFAL RQG uses unspecified packaging and is Active. RSFAL uses Tape & Reel format and is designated Not For New Designs. RSFAL RVG uses Cut Tape format and is Active. All three parts are identical in electrical performance and mechanical compatibility.

Q: Why is RSFAL marked as Not For New Designs?

A: The RSFAL carries a Not For New Designs product status designation. This is a manufacturer classification indicating that while the part remains available and functional, it is not recommended for incorporation into new product designs. For new applications, RSFAL RQG or RSFAL RVG should be selected.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tape & Reel, Cut Tape, or unspecified) affects only the distribution and handling method. Electrical specifications, thermal characteristics, and reliability parameters remain identical across all three part numbers.

Q: Are all three parts RoHS3 compliant?

A: Yes. RSFAL RQG, RSFAL, and RSFAL RVG are all RoHS3 compliant and REACH unaffected. All three carry Moisture Sensitivity Level 1 (Unlimited).

Q: Which part should be selected for a new design?

A: For new designs, select either RSFAL RQG or RSFAL RVG, as both maintain Active product status. RSFAL should not be used for new designs due to its Not For New Designs designation.

Q: What is the reverse recovery time specification?

A: All three parts have a reverse recovery time (trr) of 150 ns, classifying them as fast recovery diodes with recovery speed of ≤ 500 ns for currents > 200 mA.
