RSFGLHM2G Equivalent & Substitute Parts

Part Overview

The RSFGLHM2G 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. This component is packaged in the DO-219AB Sub SMA surface mount configuration and is classified as Active product status with AEC-Q101 automotive qualification.

Substitute parts are necessary when the primary part number becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design revisions necessitate component sourcing from existing inventory with equivalent electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the RSFGLHM2G is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 400 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 @ 400 V
• Capacitance @ Vr, F: 4 pF @ 4V, 1MHz
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Operating Temperature - Junction: -55°C to 150°C

Mechanical Equivalence Criteria:

• Package / Case: DO-219AB
• Supplier Device Package: Sub SMA
• Mounting Type: Surface Mount

Compliance Criteria:

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Substitute parts RSFGL and RSFGL RVG meet all electrical and mechanical equivalence criteria. Differences in packaging format (Tape & Reel for RSFGL; Cut Tape for RSFGL RVG) and product status do not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

RSFGLHM2G (Primary Part): This part maintains Active product status and is recommended for new designs requiring 400 V / 500 mA fast recovery rectifier diodes in DO-219AB Sub SMA packaging. The part carries AEC-Q101 automotive qualification and ROHS3 compliance.

RSFGL (Parametric Equivalent): This part is electrically and mechanically equivalent to RSFGLHM2G but carries Not For New Designs product status. RSFGL is suitable for replacement applications, legacy system maintenance, or when Tape & Reel packaging format is required for automated assembly processes. Electrical performance and compliance certifications are identical to the primary part.

RSFGL RVG (Parametric Equivalent): This part is electrically and mechanically equivalent to RSFGLHM2G and maintains Active product status. RSFGL RVG is supplied in Cut Tape packaging format and is suitable for both new designs and replacement applications when this packaging format is required for manual or semi-automated assembly processes.

Selection between RSFGLHM2G, RSFGL, and RSFGL RVG is determined by packaging format requirements and product status considerations. All three parts satisfy identical electrical and mechanical specifications for circuit applications.

Frequently Asked Questions (FAQ)

Q: Can RSFGL be used as a direct replacement for RSFGLHM2G?

A: RSFGL is electrically and mechanically equivalent to RSFGLHM2G. Both parts share identical electrical parameters (400 V reverse voltage, 500 mA current rating, 1.3 V forward voltage, 150 ns reverse recovery time) and are packaged in DO-219AB Sub SMA configuration. The primary difference is product status (RSFGL is Not For New Designs) and packaging format (Tape & Reel versus Tube). For replacement applications, RSFGL is functionally interchangeable.

Q: What is the difference between RSFGLHM2G and RSFGL RVG?

A: RSFGLHM2G and RSFGL RVG are electrically and mechanically identical. Both maintain Active product status and share all electrical specifications and DO-219AB Sub SMA packaging. The difference is packaging format: RSFGLHM2G is supplied in Tube format, while RSFGL RVG is supplied in Cut Tape format. Selection depends on assembly process requirements.

Q: Are all three parts (RSFGLHM2G, RSFGL, RSFGL RVG) suitable for automotive applications?

A: RSFGLHM2G carries AEC-Q101 automotive qualification. RSFGL and RSFGL RVG share identical electrical specifications and compliance certifications (ROHS3, REACH Unaffected) but specific automotive qualification status for these variants is not provided in the available parameters. Confirm automotive qualification requirements with the manufacturer for RSFGL and RSFGL RVG if automotive application is required.

Q: What packaging formats are available for these substitute parts?

A: RSFGLHM2G is supplied in Tube format. RSFGL is supplied in Tape & Reel (TR) format for automated assembly. RSFGL RVG is supplied in Cut Tape (CT) format for manual or semi-automated assembly. All three parts use the same DO-219AB Sub SMA physical package.

Q: Do these parts have identical reverse recovery time specifications?

A: Yes. RSFGLHM2G, RSFGL, and RSFGL RVG all specify 150 ns reverse recovery time (trr), which classifies them as fast recovery diodes with switching speed ≤ 500 ns for currents > 200 mA.

Q: Are there any compliance or regulatory differences between these parts?

A: All three parts are ROHS3 Compliant and REACH Unaffected. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts. RSFGLHM2G carries AEC-Q101 automotive qualification; automotive qualification status for RSFGL and RSFGL RVG is not specified in available parameters.
