ES1AL RFG Equivalent & Substitute Parts

Part Overview

The ES1AL 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 35 ns, suitable for standard rectification applications requiring rapid switching characteristics. The part maintains Active product status and carries full RoHS3 compliance with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across critical parameters including voltage rating, current capacity, forward voltage characteristics, and package form factor. Identifying qualified substitutes ensures design flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ES1AL RFG is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• 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)
• Package / Case: DO-219AB (Sub SMA)
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Reverse Recovery Time (trr): Variation permitted within fast recovery classification
• Current - Reverse Leakage @ Vr: Variation permitted within specified rating
• Capacitance @ Vr, F: Variation permitted based on measurement frequency and voltage conditions
• Packaging Format: Cut Tape (CT) or alternative packaging acceptable if electrical and mechanical specifications remain equivalent

The HS1AL RVG meets all mandatory equivalence criteria and qualifies as a direct parametric equivalent substitute for the ES1AL RFG.

Parameter Comparison

Engineering Selection Recommendations

Both the ES1AL RFG and HS1AL RVG are Active products manufactured by Taiwan Semiconductor Corporation with identical electrical ratings and mechanical compatibility. Selection between these parts is based on the following factors:

Compliance & Regulatory: Both parts carry ROHS3 compliance, REACH Unaffected status, and unlimited moisture sensitivity (MSL 1), meeting equivalent environmental and regulatory requirements for industrial and commercial applications.

Reverse Recovery Time Consideration: The ES1AL RFG specifies a reverse recovery time of 35 ns, while the HS1AL RVG specifies 50 ns. Both values fall within the fast recovery classification (≤ 500 ns for currents > 200 mA). Selection depends on application-specific switching speed requirements. The ES1AL RFG provides faster recovery characteristics, while the HS1AL RVG remains suitable for standard fast recovery applications.

Inventory & Availability: The HS1AL RVG maintains higher inventory availability (2549 Pcs) compared to the ES1AL RFG (682 Pcs), supporting supply chain continuity and lead time optimization.

Packaging Format: The ES1AL RFG is supplied in standard packaging, while the HS1AL RVG is supplied in Cut Tape (CT) format. Both maintain identical DO-219AB Sub SMA package specifications for surface mount assembly.

Frequently Asked Questions (FAQ)

Q: Can the HS1AL RVG replace the ES1AL RFG in existing designs?

A: Yes. The HS1AL RVG is a parametric equivalent substitute meeting all mandatory electrical and mechanical specifications. Both parts share identical voltage ratings (50 V), current capacity (1 A), forward voltage characteristics (950 mV @ 1 A), and package form factor (DO-219AB Sub SMA). Surface mount assembly compatibility is maintained.

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

A: The ES1AL RFG specifies 35 ns reverse recovery time, while the HS1AL RVG specifies 50 ns. Both values classify as fast recovery diodes (≤ 500 ns). The selection between these parts depends on application-specific switching speed requirements. For applications requiring the fastest recovery characteristics, the ES1AL RFG is specified. For standard fast recovery applications, the HS1AL RVG is acceptable.

Q: Are there packaging differences between these substitute parts?

A: Both parts use the DO-219AB Sub SMA package for surface mount applications. The ES1AL RFG is supplied in standard packaging, while the HS1AL RVG is supplied in Cut Tape (CT) format. The physical package dimensions and PCB footprint remain identical, ensuring mechanical compatibility in assembly operations.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the ES1AL RFG and HS1AL RVG carry ROHS3 compliance, REACH Unaffected status, and unlimited moisture sensitivity (MSL 1). Both parts are classified as Active products, ensuring continued availability and support.

Q: What are the operating temperature ranges for these diodes?

A: Both parts operate across identical junction temperature ranges of -55°C to 150°C, supporting applications across industrial, commercial, and extended temperature environments.

Q: Can these parts be used interchangeably in high-frequency switching applications?

A: Both parts are classified as fast recovery diodes suitable for switching applications. The ES1AL RFG provides faster recovery (35 ns) compared to the HS1AL RVG (50 ns). For high-frequency applications requiring maximum switching speed, the ES1AL RFG is specified. For standard switching applications within the fast recovery classification, the HS1AL RVG is acceptable.
