RSFGLHRFG Equivalent & Substitute Parts Reference

Part Overview

The RSFGLHRFG is a general-purpose fast recovery diode manufactured by Taiwan Semiconductor Corporation, rated for 400 V DC reverse voltage and 500 mA average rectified current. This surface mount component is packaged in DO-219AB (Sub SMA) format and is qualified to AEC-Q101 automotive standards. The part is currently in Active product status with 1011 pieces available in inventory.

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 RSFGLHRFG is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• 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
• Mounting Type: Surface Mount
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

All identified substitute parts maintain identical electrical characteristics and mechanical specifications. Differences exist only in packaging format (Tape & Reel versus Cut Tape) and product status designation, which do not affect functional performance or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

RSFGLHRFG (Primary Part): This part maintains Active product status and is suitable for new designs. It carries AEC-Q101 automotive qualification and is ROHS3 compliant. Current inventory of 1011 pieces supports immediate procurement.

RSFGL (Parametric Equivalent): This part is electrically and mechanically identical to RSFGLHRFG but carries a "Not For New Designs" product status designation. It is supplied in Tape & Reel packaging format. This part is appropriate for replacement applications, legacy system maintenance, or when Tape & Reel format is required for automated assembly processes. Significantly higher inventory (15589 pieces) provides extended availability.

RSFGL RVG (Parametric Equivalent): This part maintains Active product status and is electrically and mechanically identical to RSFGLHRFG. It is supplied in Cut Tape packaging format. This part is suitable for new designs and provides an alternative when Cut Tape format is required for manual or semi-automated assembly processes. Inventory of 14414 pieces supports sustained procurement.

All three parts are qualified to AEC-Q101 automotive standards, ROHS3 compliant, and REACH unaffected. Selection between these parts should be based on product status requirements for new designs and packaging format compatibility with manufacturing processes.

Frequently Asked Questions (FAQ)

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

A: RSFGL is electrically and mechanically equivalent to RSFGLHRFG but carries a "Not For New Designs" product status. For new design applications, RSFGLHRFG or RSFGL RVG are the appropriate selections.

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

A: All three parts are electrically identical with matching voltage ratings (400 V), current ratings (500 mA), forward voltage (1.3 V @ 500 mA), and recovery time (150 ns). The differences are: RSFGLHRFG is Active status in bulk packaging; RSFGL is Not For New Designs status in Tape & Reel format; RSFGL RVG is Active status in Cut Tape format.

Q: Are packaging format differences between these parts significant for circuit performance?

A: Packaging format differences (bulk, Tape & Reel, Cut Tape) do not affect electrical performance or circuit compatibility. Selection should be based on manufacturing assembly process requirements and product status designation.

Q: Do all substitute parts meet automotive qualification requirements?

A: Yes. RSFGLHRFG, RSFGL, and RSFGL RVG all carry AEC-Q101 automotive qualification and are ROHS3 compliant.

Q: What is the operating temperature range for these diodes?

A: The junction operating temperature range for all three parts is -55°C to 150°C.

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

A: No. All three parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.10.0070.

Q: Which part should be selected for maximum inventory availability?

A: RSFGL provides the highest inventory level at 15589 pieces. However, this part carries "Not For New Designs" status. For new designs with maximum availability, RSFGL RVG offers 14414 pieces with Active product status.
