HS1AL RHG Equivalent & Substitute Parts

Part Overview

The HS1AL RHG 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 RHG maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Identifying equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate varying packaging or inventory requirements while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the HS1AL RHG are identified based on strict electrical and mechanical parameter equivalence. The primary substitution criteria are:

Electrical Parameters (Must Match):

• 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 Parameters (Must Match):

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

Compliance & Status (Must Match):

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

Substitute parts differ only in packaging format (Cut Tape versus other formats) while maintaining identical electrical performance and mechanical compatibility.

Engineering Selection Recommendations

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

Selection Basis:

The HS1AL RVG maintains full compatibility with designs specified for the HS1AL RHG. Both parts are Active products with ROHS3 compliance and REACH unaffected status. The components are interchangeable at the circuit level, with no functional or performance differences.

The primary distinction between these parts is packaging format. The HS1AL RHG is supplied in standard packaging, while the HS1AL RVG is supplied in Cut Tape (CT) format. This difference affects handling, storage, and automated assembly processes but does not impact electrical performance or mechanical fit.

Selection between these equivalents should be based on:

• Inventory availability and lead time requirements
• Packaging format compatibility with assembly processes
• Supply chain logistics and cost considerations
• Existing stock management protocols

Both parts are suitable for direct substitution in rectification circuits requiring 50 V, 1 A fast recovery diode performance in Sub SMA surface mount packages.

Frequently Asked Questions (FAQ)

Q: Can the HS1AL RVG be used as a direct replacement for the HS1AL RHG in production designs?

A: Yes. The HS1AL RVG is electrically and mechanically equivalent to the HS1AL RHG.
