ES1AL RUG Equivalent & Substitute Parts

Part Overview

The ES1AL RUG 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 switching and rectification applications. The part maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (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 specifications. Identifying qualified substitutes ensures design flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ES1AL RUG 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
• Package / Case: DO-219AB (Sub SMA)
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C
• Technology: Standard
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Reverse Recovery Time (trr): Variation permitted within fast recovery classification (≤ 500 ns)
• Current - Reverse Leakage @ Vr: Variation permitted within specified tolerance
• Capacitance @ Vr, F: Variation permitted based on measurement frequency and voltage conditions

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

Parameter Comparison

Engineering Selection Recommendations

Both the ES1AL RUG and HS1AL RVG are Active products manufactured by Taiwan Semiconductor Corporation with identical RoHS3 compliance and REACH unaffected status. Selection between these parts is based on the following factors:

ES1AL RUG Selection Criteria:

• Shorter reverse recovery time (35 ns) for applications requiring faster switching performance
• Packaging format: Reel or standard tape configuration
• Current inventory: 666 pieces

HS1AL RVG Selection Criteria:

• Slightly longer reverse recovery time (50 ns) remains within fast recovery classification and is suitable for standard rectification applications
• Packaging format: Cut Tape (CT) for component-level procurement
• Current inventory: 2549 pieces (higher availability)

Both parts satisfy identical electrical specifications for voltage rating, current capacity, forward voltage drop, and operating temperature range. The reverse recovery time difference of 15 ns does not affect functional equivalence for general-purpose rectification applications operating within the specified fast recovery classification.

Frequently Asked Questions (FAQ)

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

A: Yes. The HS1AL RVG is a parametric equivalent substitute. Both parts share identical voltage ratings (50 V), current ratings (1 A), forward voltage characteristics (950 mV @ 1 A), package type (DO-219AB Sub SMA), and operating temperature range (-55°C to 150°C). The reverse recovery time difference (35 ns versus 50 ns) does not affect functional compatibility for general-purpose rectification applications.

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

A: The ES1AL RUG has a reverse recovery time of 35 ns, while the HS1AL RVG has 50 ns. Both values fall within the fast recovery classification (≤ 500 ns). This 15 ns difference is negligible for standard rectification circuits and does not impact switching performance in typical applications. Selection should be based on specific circuit timing requirements if present.

Q: Are there packaging differences between these substitute parts?

A: Both parts use the DO-219AB Sub SMA package for surface mount applications. The primary packaging difference is the supplier format: ES1AL RUG is available in standard reel configuration, while HS1AL RVG is supplied in Cut Tape (CT) format. Both are compatible with standard pick-and-place assembly equipment.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the ES1AL RUG and HS1AL RVG are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level). Both parts maintain Active product status with identical regulatory certifications.

Q: Which part should be selected based on availability?

A: The HS1AL RVG currently has higher inventory availability (2549 pieces) compared to the ES1AL RUG (666 pieces). If supply chain continuity is a priority and electrical specifications are equivalent, the HS1AL RVG provides greater stock availability.

Q: Are there any thermal or leakage current differences that affect circuit design?

A: No. Both parts share identical reverse leakage current specifications (5 µA @ 50 V) and identical operating temperature ranges (-55°C to 150°C). Thermal and leakage characteristics are equivalent for circuit design purposes.
