ES1AL RVG Equivalent & Substitute Parts

Part Overview

The ES1AL RVG is a general-purpose surface mount rectifier diode manufactured by Taiwan Semiconductor Corporation. This component operates at 50 V DC reverse voltage with 1 A average rectified current capacity and features fast recovery characteristics suitable for standard rectification applications. The part is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility within specified parameter tolerances.

Substitute Part Grouping Explanation

Substitute parts for the ES1AL RVG are identified based on strict electrical and mechanical parameter matching. The primary substitution criterion requires identical ratings across the following parameters: maximum DC reverse voltage (50 V), average rectified current (1 A), forward voltage drop (950 mV @ 1 A), package type (DO-219AB Sub SMA), mounting configuration (Surface Mount), operating temperature range (-55°C to 150°C), and compliance certifications (RoHS3, REACH Unaffected).

The HS1AL RVG qualifies as a parametric equivalent substitute. Both components share identical voltage ratings, current capacity, forward voltage characteristics, package designation, and thermal operating range. Variations in reverse recovery time (35 ns versus 50 ns) and junction capacitance (10 pF versus 20 pF) remain within acceptable tolerance for general-purpose rectification applications. Both parts maintain equivalent compliance status and moisture sensitivity classification.

Engineering Selection Recommendations

Both ES1AL RVG and HS1AL RVG maintain Active product status with full regulatory compliance. Selection between these components is determined by packaging and inventory requirements rather than electrical performance differentiation.

The ES1AL RVG is supplied in Tape & Reel (TR) packaging format, suitable for high-volume automated assembly operations. The HS1AL RVG is supplied in Cut Tape (CT) packaging format, appropriate for lower-volume or manual assembly processes. Both packaging formats contain identical diode specifications and comply with RoHS3 and REACH requirements.

Inventory availability differs between variants: ES1AL RVG maintains 839 pieces in stock, while HS1AL RVG maintains 2549 pieces in stock. Component selection should align with production volume requirements and supply chain lead time considerations.

Frequently Asked Questions (FAQ)

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

A: Yes. Both components share identical electrical ratings (50 V reverse voltage, 1 A average rectified current, 950 mV forward voltage drop) and operate within the same temperature range (-55°C to 150°C). The primary difference is packaging format: ES1AL RVG uses Tape & Reel while HS1AL RVG uses Cut Tape. Circuit performance remains equivalent.

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

A: ES1AL RVG specifies 35 ns reverse recovery time while HS1AL RVG specifies 50 ns. Both components meet the Fast Recovery classification (≤ 500 ns for currents > 200 mA). The 15 ns difference does not affect general-purpose rectification applications.

Q: Are there compliance differences between ES1AL RVG and HS1AL RVG?

A: No. Both components are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. Regulatory and environmental compliance is identical.

Q: Which packaging format should be selected for production?

A: Tape & Reel (TR) packaging is standard for automated pick-and-place assembly at high volumes. Cut Tape (CT) packaging is suitable for manual assembly, prototyping, or lower-volume production runs. Select based on assembly process requirements and production volume.

Q: Is the junction capacitance difference significant?

A: ES1AL RVG specifies 10 pF junction capacitance while HS1AL RVG specifies 20 pF at 4 V and 1 MHz. For general-purpose rectification applications, this difference is not functionally significant. High-frequency switching applications should evaluate capacitance impact on circuit performance.
