RSFGLHMHG Equivalent & Substitute Parts Reference

Part Overview

The RSFGLHMHG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 400 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 carries 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 across different distribution channels.

Substitute Part Grouping Explanation

Substitution eligibility for the RSFGLHMHG is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for a part to function as a direct substitute:

• 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
• Operating Temperature - Junction: -55°C to 150°C
• Package / Case: DO-219AB (Sub SMA)
• Mounting Type: Surface Mount
• Technology: Standard
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Substitute parts may differ only in packaging format (Tape & Reel, Cut Tape, or Bulk) and product status designation, provided all electrical characteristics and physical package specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

RSFGLHMHG (Primary Part): This part maintains Active product status and is suitable for new designs. It is available in bulk packaging format with 1126 pieces in current inventory. The part carries AEC-Q101 automotive qualification and full ROHS3 compliance.

RSFGL (Parametric Equivalent): This part is electrically and mechanically identical to RSFGLHMHG but carries a "Not For New Designs" product status designation. It is supplied in Tape & Reel format with 15589 pieces in inventory. This part is suitable for replacement applications, legacy system support, or high-volume manufacturing where tape and reel packaging is required. The higher inventory level reflects its legacy status.

RSFGL RVG (Parametric Equivalent): This part is electrically and mechanically identical to RSFGLHMHG and maintains Active product status. It is supplied in Cut Tape format with 14414 pieces in inventory. This part is suitable for new designs requiring cut tape packaging or for applications where individual component handling is preferred over bulk or reel formats.

All three parts satisfy identical electrical performance requirements, automotive qualification standards, and regulatory compliance obligations. Selection between them depends on packaging format requirements and product lifecycle considerations.

Frequently Asked Questions (FAQ)

Q: Can RSFGL be used as a direct replacement for RSFGLHMHG in new designs?

A: RSFGL is electrically and mechanically identical to RSFGLHMHG and meets all electrical specifications. However, RSFGL carries a "Not For New Designs" product status. For new design applications, RSFGLHMHG or RSFGL RVG are the appropriate selections.

Q: What is the difference between the three part numbers?

A: All three parts (RSFGLHMHG, RSFGL, and RSFGL RVG) are parametrically equivalent with identical electrical characteristics and DO-219AB package specifications. The differences are: packaging format (bulk, tape & reel, or cut tape) and product status (Active or Not For New Designs).

Q: Are the packaging formats interchangeable?

A: The packaging formats (bulk, Tape & Reel, and Cut Tape) are different distribution methods for the same component. The actual diode specifications and performance are identical. Selection depends on manufacturing process requirements and assembly equipment compatibility.

Q: Does RSFGL RVG have the same automotive qualification as RSFGLHMHG?

A: Both RSFGLHMHG and RSFGL RVG carry AEC-Q101 automotive qualification. RSFGL also meets AEC-Q101 requirements. All three parts are suitable for automotive applications.

Q: What is the significance of the "Not For New Designs" status on RSFGL?

A: "Not For New Designs" indicates that while RSFGL remains available and fully functional, the manufacturer recommends using alternative part numbers (RSFGLHMHG or RSFGL RVG) for new product development. This designation typically reflects product lifecycle management and does not indicate any technical deficiency.

Q: Are all three parts ROHS3 compliant?

A: Yes, RSFGLHMHG, RSFGL, and RSFGL RVG are all ROHS3 compliant with MSL rating of 1 (Unlimited) and REACH Unaffected status.

Q: Can I substitute these parts in existing circuit designs without modification?

A: Yes. All three parts are parametrically equivalent with identical electrical characteristics (400 V reverse voltage, 500 mA current rating, 1.3 V forward voltage, 150 ns reverse recovery time) and identical DO-219AB package specifications. No circuit modifications are required.
