RS1ALHRVG Equivalent & Substitute Parts

Part Overview

The RS1ALHRVG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 50 V DC reverse voltage and 800 mA average rectified current. This component is classified as a fast recovery diode with a reverse recovery time of 150 ns, packaged in the DO-219AB (Sub SMA) surface mount configuration. The part maintains Active product status and carries AEC-Q101 automotive qualification with ROHS3 compliance.

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 parametric family.

Substitute Part Grouping Explanation

Substitution eligibility for the RS1ALHRVG is determined by strict parametric matching across all electrical and mechanical specifications. The following criteria establish valid substitutes:

Electrical Parameters (Must Match Exactly):

• Voltage - DC Reverse (Vr) (Max): 50 V
• Current - Average Rectified (Io): 800 mA
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 800 mA
• Reverse Recovery Time (trr): 150 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 50 V
• Capacitance @ Vr, F: 10 pF @ 4V, 1MHz

Mechanical Parameters (Must Match Exactly):

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

Compliance & Qualification (Must Match or Exceed):

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

Substitute parts may differ in packaging format (Tape & Reel, Cut Tape, or bulk) and product status classification, provided all electrical and mechanical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

RS1ALHRVG (Primary Part): This part maintains Active product status and is suitable for new design implementations. It carries AEC-Q101 automotive qualification and ROHS3 compliance. The bulk packaging format is appropriate for prototype development and low-volume applications.

RS1AL (Substitute): This part is classified as Not For New Designs and should be used only for legacy system maintenance, repair, or replacement applications where existing inventory must be sustained. All electrical and mechanical parameters are identical to the primary part. The Tape & Reel packaging format is optimized for high-volume automated assembly processes.

RS1AL RVG (Substitute): This part maintains Active product status and is suitable for new design implementations. All electrical and mechanical parameters are identical to the primary part. The Cut Tape packaging format provides flexibility for moderate-volume production runs and manual assembly operations.

Selection between RS1ALHRVG and RS1AL RVG for new designs should be based on manufacturing process requirements and packaging format compatibility. Both parts carry identical electrical specifications and Active product status. The RS1AL part should be avoided in new designs due to its Not For New Designs classification.

Frequently Asked Questions (FAQ)

Q: Can RS1AL be used as a direct replacement for RS1ALHRVG in new product designs?

A: No. The RS1AL carries a Not For New Designs product status classification. For new design implementations, use either RS1ALHRVG or RS1AL RVG, both of which maintain Active product status.

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

A: RS1ALHRVG is supplied in bulk format. RS1AL is supplied in Tape & Reel (TR) format, optimized for high-volume automated pick-and-place assembly. RS1AL RVG is supplied in Cut Tape (CT) format, suitable for moderate-volume production and manual assembly operations. All three formats contain identical components with identical electrical specifications.

Q: Are all three parts electrically interchangeable?

A: Yes. RS1ALHRVG, RS1AL, and RS1AL RVG are electrically identical. All three parts share identical voltage ratings (50 V), current ratings (800 mA), forward voltage characteristics (1.3 V @ 800 mA), reverse recovery time (150 ns), leakage current (5 µA @ 50 V), and capacitance (10 pF @ 4V, 1MHz).

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). RS1ALHRVG and RS1AL RVG both carry AEC-Q101 automotive qualification.

Q: Which part should be selected for high-volume manufacturing?

A: RS1AL RVG is recommended for high-volume manufacturing due to its Active product status and Cut Tape packaging format, which is compatible with standard automated assembly equipment. RS1AL in Tape & Reel format is also suitable for high-volume applications but should not be used in new designs.

Q: Can these parts be used interchangeably in automotive applications?

A: RS1ALHRVG and RS1AL RVG both carry AEC-Q101 automotive qualification and are suitable for automotive applications. RS1AL does not list automotive qualification in the provided specifications.

Q: What is the operating temperature range for all substitute parts?

A: All three parts operate across a junction temperature range of -55°C to 150°C, suitable for industrial and automotive temperature environments.
