RSFALHRTG Equivalent & Substitute Parts

Part Overview

The RSFALHRTG 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 standards (AEC-Q101).

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 with equivalent electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RSFALHRTG is permissible with equivalent part numbers that maintain identical electrical characteristics across all critical parameters. The substitution logic is based on the following key parameters that determine functional equivalence:

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

Physical and Compliance Parameters:

• Package / Case: DO-219AB (Sub SMA)
• Mounting Type: Surface Mount
• Technology: Standard
• RoHS Status: ROHS3 Compliant
• Operating Temperature - Junction: -55°C to 150°C

Substitute parts RSFAL and RSFAL RVG are equivalent to RSFALHRTG based on identical electrical performance specifications. Differences exist only in packaging format (Tape & Reel versus Cut Tape) and product status designation, which do not affect functional performance in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

RSFALHRTG (Primary Part): This part maintains Active product status and is suitable for new designs. It provides full compliance with automotive-grade qualification (AEC-Q101) and ROHS3 standards. Selection of this part number is appropriate for applications requiring current production support and long-term availability assurance.

RSFAL (Substitute Part): This part is electrically equivalent to RSFALHRTG with identical electrical performance specifications. However, it carries a "Not For New Designs" product status designation. RSFAL is available in Tape & Reel packaging format and maintains full compliance with RoHS3 and REACH requirements. This part is suitable for replacement applications, legacy system support, or when Tape & Reel packaging is required for automated assembly processes.

RSFAL RVG (Substitute Part): This part is electrically equivalent to RSFALHRTG with identical electrical performance specifications. It maintains Active product status and is suitable for new designs. RSFAL RVG is available in Cut Tape packaging format, which is appropriate for manual assembly, small-volume production, or component kitting applications. Full compliance with RoHS3 and REACH requirements is maintained.

Selection between substitute parts should be based on packaging format requirements (Tape & Reel for high-volume automated assembly, Cut Tape for manual or low-volume assembly) and product status considerations for new design implementations.

Frequently Asked Questions (FAQ)

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

A: RSFAL is electrically equivalent to RSFALHRTG and will function identically in circuit applications. However, RSFAL carries a "Not For New Designs" product status. For new design implementations, RSFAL RVG is the recommended substitute, as it maintains Active product status while providing identical electrical characteristics.

Q: What is the difference between the packaging formats offered?

A: RSFALHRTG is supplied in standard packaging format. RSFAL is supplied in Tape & Reel (TR) format, which is optimized for high-volume automated assembly processes. RSFAL RVG is supplied in Cut Tape (CT) format, which is suitable for manual assembly, component kitting, or low-volume production runs. All three part numbers contain identical diode components in the same DO-219AB package.

Q: Are all substitute parts compliant with automotive and environmental standards?

A: Yes. RSFALHRTG, RSFAL, and RSFAL RVG all meet AEC-Q101 automotive qualification requirements, ROHS3 compliance, and REACH unaffected status. All parts maintain identical operating temperature ranges (-55°C to 150°C junction temperature) and moisture sensitivity levels (MSL 1 - Unlimited).

Q: What electrical parameters must remain identical for substitution?

A: Substitution is valid when the following parameters are identical: Voltage - DC Reverse (50V), Current - Average Rectified (500mA), Voltage - Forward (1.3V @ 500mA), Reverse Recovery Time (150ns), Current - Reverse Leakage (5µA @ 50V), and Capacitance (4pF @ 4V, 1MHz). All substitute parts listed maintain these specifications.

Q: Can RSFAL RVG be used in automated assembly processes?

A: RSFAL RVG is supplied in Cut Tape format, which is designed for manual assembly or component kitting applications. For high-volume automated assembly processes requiring continuous tape feeding, RSFAL in Tape & Reel format is the appropriate selection.

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

A: No. RSFALHRTG, RSFAL, and RSFAL RVG are electrically and functionally identical. Differences exist only in packaging format and product status designation, which do not affect circuit performance or electrical characteristics.
