RSFALHM2G Equivalent & Substitute Parts

Part Overview

The RSFALHM2G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 50V DC reverse voltage and 500mA average rectified current in a Sub SMA surface mount package. This component is classified as Active product status and meets automotive-grade qualification per AEC-Q101 standard.

Substitute parts become necessary when the primary part number reaches end-of-life status, when specific packaging formats are required for manufacturing processes, or when inventory constraints necessitate alternative sourcing from the same parametric family. The RSFALHM2G maintains full electrical and mechanical compatibility with designated substitute part numbers within the RSFAL series.

Substitute Part Grouping Explanation

Substitution within the RSFALHM2G family is determined by strict equivalence across all critical electrical parameters. The following parameters must remain identical for a part to qualify as a direct substitute:

  • 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
  • Technology: Standard
  • Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Substitute parts differ only in packaging format (Tape & Reel or Cut Tape) and product status designation. All substitutes maintain identical electrical performance and mechanical compatibility with the primary part number.

Engineering Selection Recommendations

RSFALHM2G (Primary Part): This part maintains Active product status and is suitable for new design implementations. It carries automotive-grade qualification per AEC-Q101 and full ROHS3 compliance. Current inventory of 758 pieces supports immediate procurement requirements.

RSFAL (Substitute): This part number is designated as Not For New Designs and represents an earlier product generation. It maintains identical electrical and mechanical specifications but is supplied in Tape & Reel packaging format. This part is appropriate for legacy system maintenance or replacement applications where existing design documentation references this part number. Inventory availability of 9,885 pieces provides extended supply continuity.

RSFAL RVG (Substitute): This part maintains Active product status and is supplied in Cut Tape packaging format. It provides an alternative to RSFALHM2G when Cut Tape format is required by manufacturing processes or inventory management systems. Electrical and mechanical specifications are identical to the primary part. Inventory of 7,680 pieces supports sustained procurement.

Selection between these three part numbers depends on packaging format requirements and product lifecycle status. All three parts satisfy identical electrical performance criteria and automotive-grade compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can RSFAL be used as a direct replacement for RSFALHM2G in new designs?

A: RSFAL is designated as Not For New Designs. While electrical and mechanical parameters are identical, new design implementations should utilize RSFALHM2G or RSFAL RVG, both carrying Active product status.

Q: What is the difference between RSFALHM2G, RSFAL, and RSFAL RVG?

A: All three parts are electrically and mechanically identical, with 50V reverse voltage rating, 500mA average rectified current, and DO-219AB Sub SMA package. The differences are: RSFALHM2G uses standard packaging, RSFAL is supplied in Tape & Reel format with Not For New Designs status, and RSFAL RVG is supplied in Cut Tape format with Active status.

Q: Are these parts suitable for automotive applications?

A: Yes. All three parts carry automotive-grade classification and AEC-Q101 qualification, meeting automotive industry standards.

Q: What packaging formats are available?

A: RSFALHM2G is supplied in standard packaging format, RSFAL in Tape & Reel (TR), and RSFAL RVG in Cut Tape (CT). Packaging format selection depends on manufacturing assembly requirements and inventory management processes.

Q: Do all substitute parts meet RoHS compliance?

A: Yes. RSFALHM2G, RSFAL, and RSFAL RVG are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).
