RSFAL RHG Equivalent & Substitute Parts

Part Overview

The RSFAL RHG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, designed for surface mount applications in the Sub SMA package format. This component operates at 50 V DC reverse voltage with a 500 mA average rectified current rating, featuring fast recovery characteristics suitable for standard rectification circuits. The part is currently in Active product status with full RoHS3 compliance and REACH unaffected designation.

Substitute parts become necessary when the original packaging format is unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits equivalent electrical performance with different packaging configurations. The RSFAL RHG maintains identical electrical specifications across all qualified substitutes while offering different packaging and delivery formats.

Substitute Part Grouping Explanation

Substitution eligibility for the RSFAL RHG rectifier diode is determined by strict equivalence across the following critical electrical 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

All qualified substitutes maintain identical electrical performance and thermal specifications. Differences exist only in packaging format (Tape & Reel versus Cut Tape) and product status designation. The base product number RSFAL remains constant across all variants, confirming parametric equivalence.

Engineering Selection Recommendations

RSFAL RHG (Primary Selection)

The RSFAL RHG is the recommended selection for new designs. This part maintains Active product status, indicating full manufacturer support and continued availability. It provides standard packaging suitable for general component procurement workflows.

RSFAL RVG (Preferred Substitute)

The RSFAL RVG is the primary substitute option. This variant maintains Active product status identical to the main part and offers Cut Tape packaging format. All electrical parameters, thermal specifications, compliance certifications (RoHS3, REACH Unaffected), and moisture sensitivity ratings are identical to RSFAL RHG. Selection of RSFAL RVG is appropriate when Cut Tape packaging meets assembly requirements.

RSFAL (Secondary Substitute)

The RSFAL variant is designated as Not For New Designs and carries Tape & Reel packaging. While electrically and thermally equivalent to RSFAL RHG, this part should be selected only when existing inventory constraints or legacy design requirements necessitate its use. The Not For New Designs status indicates reduced manufacturer support and potential future discontinuation.

All three variants maintain identical RoHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level 1 (Unlimited) designation, confirming suitability for equivalent circuit applications.

Frequently Asked Questions (FAQ)

Q: Are RSFAL RHG, RSFAL, and RSFAL RVG electrically interchangeable?

A: Yes. All three parts share identical electrical specifications including 50 V reverse voltage rating, 500 mA average rectified current, 1.3 V forward voltage drop at 500 mA, 150 ns reverse recovery time, and identical operating temperature range (-55°C to 150°C). They are parametrically equivalent and functionally interchangeable in circuit applications.

Q: What is the difference between these substitute parts?

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

Q: Can I use RSFAL (Not For New Designs) in a new design?

A: RSFAL carries a Not For New Designs designation, indicating reduced manufacturer support. For new designs, RSFAL RHG or RSFAL RVG are the appropriate selections, both maintaining Active product status.

Q: Do all variants have the same compliance certifications?

A: Yes. All three parts are RoHS3 Compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). Compliance certifications are identical across all variants.

Q: Which packaging format should I select?

A: Packaging selection depends on assembly process requirements. RSFAL RHG provides standard packaging, RSFAL RVG provides Cut Tape format for automated pick-and-place operations, and RSFAL provides Tape & Reel format for high-volume production. All three formats are compatible with surface mount assembly processes for the DO-219AB package.

Q: Are there inventory differences between these parts?

A: Yes. Current inventory levels differ: RSFAL RHG has 874 pieces in stock, RSFAL has 9885 pieces, and RSFAL RVG has 7680 pieces. Inventory availability may influence selection when immediate delivery is required.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the circuit board layout and assembly process accommodate the DO-219AB Sub SMA package format. All electrical performance characteristics remain identical, ensuring functional equivalence in existing circuit designs.
