HS1AL RFG Equivalent & Substitute Parts

Part Overview

The HS1AL RFG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 50 V DC reverse voltage and 1 A average rectified current in a Sub SMA surface mount package. This component is classified as a fast recovery diode with a reverse recovery time of 50 ns, suitable for standard rectification applications requiring compact form factors.

The HS1AL RFG maintains Active product status and is ROHS3 compliant. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable, while maintaining identical electrical performance and mechanical compatibility within the specified parameter ranges.

Substitute Part Grouping Explanation

Substitute parts for the HS1AL RFG are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic requires that alternative parts maintain:

Electrical Parameter Equivalence:

• Voltage - DC Reverse (Vr) (Max): 50 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 950 mV @ 1 A
• Reverse Recovery Time (trr): 50 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 50 V
• Capacitance @ Vr, F: 20 pF @ 4V, 1MHz
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameter Equivalence:

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

Compliance Equivalence:

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

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The HS1AL RVG is a direct parametric equivalent to the HS1AL RFG. Both components are manufactured by Taiwan Semiconductor Corporation and share identical electrical specifications, mechanical dimensions, and compliance certifications.

Selection Basis:

Both parts maintain Active product status and are ROHS3 compliant with REACH Unaffected classification. The electrical parameters are identical across all measured specifications: 50 V reverse voltage rating, 1 A average rectified current, 950 mV forward voltage drop at 1 A, 50 ns reverse recovery time, and 5 µA reverse leakage current at rated voltage.

The mechanical compatibility is confirmed through identical DO-219AB package designation and Sub SMA supplier device package classification. Both components support surface mount assembly with identical operating temperature ranges of -55°C to 150°C.

The primary distinction between these parts is packaging format: HS1AL RFG is supplied in standard packaging, while HS1AL RVG is supplied in Cut Tape (CT) format. This difference affects only the delivery and handling method, not the component performance or circuit compatibility.

Selection between these parts should be based on packaging requirements and inventory availability. Both parts are suitable for direct substitution in applications requiring 50 V, 1 A fast recovery rectifier diodes in Sub SMA surface mount packages.
