RSFAL M2G Equivalent & Substitute Parts

Part Overview

The RSFAL M2G 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 surface mount component features fast recovery characteristics with a reverse recovery time of 150 ns and is housed in a DO-219AB package (Sub SMA form factor). The part is classified as Active product status and is RoHS3 compliant.

Substitute parts are necessary when the original RSFAL M2G packaging format (standard packaging) is unavailable or when alternative packaging configurations such as Tape & Reel or Cut Tape are required for manufacturing processes. Substitute parts maintain identical electrical and mechanical specifications while offering different distribution formats.

Substitute Part Grouping Explanation

Substitute parts for the RSFAL M2G are determined by equivalence 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

All substitute parts listed maintain identical electrical performance and mechanical compatibility. Differences exist only in packaging format and product status designation. The RSFAL and RSFAL RVG variants are available in alternative distribution formats (Tape & Reel and Cut Tape respectively) while preserving all functional specifications.

Engineering Selection Recommendations

RSFAL M2G (Primary Part)

The RSFAL M2G is designated as Active product status and is suitable for new design implementations. This part number represents the standard packaging format and is the preferred selection for applications requiring current component qualification.

RSFAL (Tape & Reel Format)

The RSFAL variant is available in Tape & Reel packaging and maintains full electrical and mechanical equivalence to RSFAL M2G. However, this part is designated as Not For New Designs. Selection of this variant is appropriate only when existing inventory or manufacturing processes specifically require Tape & Reel distribution format and when design qualification has already been completed with this packaging configuration.

RSFAL RVG (Cut Tape Format)

The RSFAL RVG variant is available in Cut Tape packaging and is designated as Active product status. This part maintains full electrical and mechanical equivalence to RSFAL M2G and is suitable for new designs when Cut Tape distribution format is required by manufacturing or procurement specifications.

All three variants are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity classification, ensuring compatibility with standard surface mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RSFAL M2G be directly replaced with RSFAL or RSFAL RVG in circuit applications?

A: Yes. All three part numbers are electrically and mechanically 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), and all other functional parameters. Substitution is valid from a circuit performance perspective.

Q: What is the difference between RSFAL M2G, RSFAL, and RSFAL RVG?

A: The differences are limited to packaging format and product status. RSFAL M2G uses standard packaging, RSFAL uses Tape & Reel format, and RSFAL RVG uses Cut Tape format. RSFAL M2G and RSFAL RVG are Active products, while RSFAL is designated Not For New Designs.

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

A: Product status designations reflect manufacturer recommendations for design phase selection. The Not For New Designs status indicates that RSFAL should not be selected for new circuit designs. However, the part remains functionally equivalent and may be used in existing designs or when specific manufacturing constraints require Tape & Reel packaging.

Q: Are all three parts RoHS3 compliant?

A: Yes. RSFAL M2G, RSFAL, and RSFAL RVG are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the moisture sensitivity level for these diodes?

A: All three variants carry MSL 1 (Unlimited) classification, indicating unlimited shelf life under normal storage conditions without special moisture control requirements.

Q: Can these parts be used interchangeably in automated assembly processes?

A: Electrical and mechanical substitution is valid. However, manufacturing process compatibility depends on specific assembly equipment and tape specifications. Tape & Reel (RSFAL) and Cut Tape (RSFAL RVG) formats may require different feeder configurations. Standard packaging (RSFAL M2G) compatibility depends on the specific assembly process used.

Q: What is the operating temperature range for these diodes?

A: The junction operating temperature range is -55°C to 150°C for all three variants, providing thermal performance suitable for industrial and commercial applications.
