RSFGLHRUG Equivalent & Substitute Parts

Part Overview

The RSFGLHRUG 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 in a Sub SMA surface mount package. This component is classified as Active product status and meets AEC-Q101 automotive qualification standards.

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 manufacturer's product line. The RSFGLHRUG maintains full electrical and mechanical compatibility with designated substitute part numbers that share identical core specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSFGLHRUG is determined by strict equivalence across the following critical parameters:

Electrical Specifications (Must Match Exactly):

• 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

Mechanical Specifications (Must Match Exactly):

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

Compliance & Certification (Must Match Exactly):

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

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

Parameter Comparison

Engineering Selection Recommendations

RSFGLHRUG (Primary Part): This part number is designated as Active product status and is suitable for new designs and ongoing production. It provides the baseline reference for all equivalent substitutions and maintains full AEC-Q101 automotive qualification.

RSFGL (Parametric Equivalent): This part number is designated as Not For New Designs and is retained in inventory for legacy system support and field replacements. It is electrically and mechanically identical to RSFGLHRUG but is supplied in Tape & Reel packaging format. Selection of this part number is appropriate only when existing designs or manufacturing processes specifically require Tape & Reel packaging or when legacy system compatibility is the primary requirement.

RSFGL RVG (Parametric Equivalent): This part number is designated as Active product status and is suitable for new designs. It is electrically and mechanically identical to RSFGLHRUG but is supplied in Cut Tape packaging format. Selection of this part number is appropriate when manufacturing processes require Cut Tape packaging or when inventory sourcing from this specific variant is necessary.

All three part numbers maintain identical electrical performance, thermal characteristics, and compliance certifications. Selection between them is determined solely by packaging format requirements and product status considerations for new design qualification.

Frequently Asked Questions (FAQ)

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

A: RSFGL is designated as Not For New Designs. While it is electrically and mechanically identical to RSFGLHRUG, it is not qualified for new design implementations. RSFGLHRUG or RSFGL RVG are the appropriate selections for new designs.

Q: What is the difference between RSFGLHRUG, RSFGL, and RSFGL RVG?

A: All three part numbers are electrically and mechanically identical. The differences are limited to packaging format and product status. RSFGLHRUG is supplied in bulk packaging, RSFGL is supplied in Tape & Reel format with Not For New Designs status, and RSFGL RVG is supplied in Cut Tape format with Active status.

Q: Are there any electrical performance differences between the substitute parts?

A: No. All substitute parts maintain identical electrical specifications including voltage ratings, current ratings, forward voltage drop, reverse recovery time, reverse leakage current, and capacitance characteristics.

Q: What packaging formats are available for this diode?

A: The RSFGLHRUG is available in three packaging formats: bulk (RSFGLHRUG), Tape & Reel (RSFGL), and Cut Tape (RSFGL RVG). All use the DO-219AB package with Sub SMA supplier device package designation.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. RSFGLHRUG, RSFGL, and RSFGL RVG are all ROHS3 Compliant with REACH Unaffected status and Moisture Sensitivity Level 1 (Unlimited).

Q: Which part number should be selected for automotive applications?

A: All three part numbers meet AEC-Q101 automotive qualification standards. Selection should be based on packaging format requirements and product status. RSFGLHRUG and RSFGL RVG are both Active status and suitable for automotive new designs.

Q: Can RSFGL RVG be used in place of RSFGLHRUG?

A: Yes. RSFGL RVG is a direct electrical and mechanical equivalent to RSFGLHRUG. The only difference is the Cut Tape packaging format. Selection of RSFGL RVG is appropriate when manufacturing processes require Cut Tape packaging or when this variant is the available inventory source.
