ES1AL R3G Equivalent & Substitute Parts

Part Overview

The ES1AL R3G 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 Active product status and is RoHS3 compliant. Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or inventory limitations while maintaining identical or compatible electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the ES1AL R3G is permissible with the HS1AL RVG based on the following criteria:

Matching Parameters (Substitution Basis):

• Voltage - DC Reverse (Vr) (Max): 50 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 950 mV @ 1 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Mounting Type: Surface Mount
• Package / Case: DO-219AB (Sub SMA)
• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Parameter Variations:

• Reverse Recovery Time (trr): 35 ns (ES1AL R3G) versus 50 ns (HS1AL RVG) — both within fast recovery classification
• Capacitance @ Vr, F: 10 pF @ 1V, 1MHz (ES1AL R3G) versus 20 pF @ 4V, 1MHz (HS1AL RVG) — minor variation acceptable for general-purpose rectification
• Packaging Format: Reel (ES1AL R3G) versus Cut Tape (CT) (HS1AL RVG) — mechanical packaging difference only

Parameter Comparison

Engineering Selection Recommendations

Both the ES1AL R3G and HS1AL RVG are Active product status components manufactured by Taiwan Semiconductor Corporation with identical RoHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and packaging format requirements:

ES1AL R3G is suitable for applications where reel packaging is required and inventory availability is confirmed at 749 pieces.

HS1AL RVG is suitable for applications where cut tape packaging is acceptable and higher inventory availability is required, with 2549 pieces in stock. The HS1AL RVG exhibits a slightly higher reverse recovery time (50 ns versus 35 ns) and higher capacitance (20 pF versus 10 pF), both of which remain within acceptable parameters for general-purpose rectification applications and do not compromise functional equivalence.

Both parts maintain identical electrical ratings for voltage, current, forward voltage drop, and operating temperature range, ensuring direct functional substitution in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the HS1AL RVG directly replace the ES1AL R3G in existing circuit designs?

A: Yes. Both parts share identical voltage ratings (50 V), current ratings (1 A), forward voltage characteristics (950 mV @ 1 A), and operating temperature range (-55°C to 150°C). The HS1AL RVG exhibits minor variations in reverse recovery time (50 ns versus 35 ns) and capacitance (20 pF versus 10 pF), which do not affect functional equivalence for general-purpose rectification applications.

Q: Are there any package compatibility concerns between ES1AL R3G and HS1AL RVG?

A: Both parts use the DO-219AB Sub SMA package with identical surface mount footprints. The only difference is the supply format: ES1AL R3G is supplied on reel, while HS1AL RVG is supplied in cut tape. This is a mechanical packaging distinction that does not affect PCB assembly compatibility.

Q: What is the significance of the reverse recovery time difference between these parts?

A: The ES1AL R3G has a reverse recovery time of 35 ns, while the HS1AL RVG has 50 ns. Both are classified as fast recovery diodes (≤ 500 ns). This minor difference does not impact general-purpose rectification performance and remains within acceptable parameters for standard switching applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the ES1AL R3G and HS1AL RVG are RoHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 1 - Unlimited). They are functionally equivalent from a regulatory and environmental compliance perspective.

Q: Which part should be selected based on inventory considerations?

A: The HS1AL RVG offers significantly higher inventory availability (2549 pieces) compared to the ES1AL R3G (749 pieces). For applications requiring immediate availability or larger volume requirements, the HS1AL RVG is the preferred selection.
