ES1ALHRUG Equivalent & Substitute Parts

Part Overview

The ES1ALHRUG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 50 V DC reverse voltage and 1 A average rectified current. This component is classified as a fast recovery diode with a reverse recovery time of 35 ns, suitable for surface mount applications in the Sub SMA package format (DO-219AB). The part maintains Active product status and carries AEC-Q101 automotive qualification, making it suitable for automotive and industrial applications requiring reliable rectification performance.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same functional category, allowing for design flexibility, inventory optimization, and supply chain continuity without compromising circuit performance.

Substitute Part Grouping Explanation

Substitution eligibility for the ES1ALHRUG is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• 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)
• Current - Reverse Leakage @ Vr: 5 µA @ 50 V

Mechanical Equivalence Requirements:

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

Compliance Requirements:

• RoHS Status: ROHS3 Compliant
• Product Status: Active

The HS1AL RVG meets all electrical and mechanical equivalence criteria, maintaining identical voltage ratings, current ratings, forward voltage characteristics, and package specifications. Both parts are manufactured by Taiwan Semiconductor Corporation, carry ROHS3 compliance, and maintain Active product status. Reverse recovery time (trr) and junction capacitance exhibit minor variations within acceptable engineering tolerances for general-purpose rectification applications.

Parameter Comparison

Engineering Selection Recommendations

Both ES1ALHRUG and HS1AL RVG are qualified for direct substitution based on electrical and mechanical parameter equivalence. Selection between these parts should be based on the following factors:

Inventory and Availability: The HS1AL RVG maintains higher inventory levels (2549 Pcs) compared to ES1ALHRUG (1032 Pcs), providing improved supply chain availability for high-volume production requirements.

Reverse Recovery Time Performance: The ES1ALHRUG exhibits a faster reverse recovery time of 35 ns compared to HS1AL RVG at 50 ns. Applications requiring minimal switching losses or operating at higher switching frequencies benefit from the ES1ALHRUG specification.

Junction Capacitance: The ES1ALHRUG specifies 10 pF junction capacitance versus 20 pF for HS1AL RVG. Circuits sensitive to parasitic capacitance effects or operating at high frequencies should prioritize the ES1ALHRUG.

Compliance and Qualification: Both parts maintain identical compliance certifications: ROHS3 compliance, REACH Unaffected status, and AEC-Q101 automotive qualification. Both are suitable for automotive and industrial applications without additional qualification requirements.

Packaging Format: Both parts are supplied in DO-219AB Sub SMA surface mount packages with identical mounting characteristics, ensuring direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can HS1AL RVG be used as a direct replacement for ES1ALHRUG in automotive applications?

A: Yes. Both parts carry AEC-Q101 automotive qualification and maintain identical voltage ratings (50 V), current ratings (1 A), forward voltage characteristics (950 mV @ 1 A), and operating temperature ranges (-55°C to 150°C). Both are ROHS3 compliant and REACH Unaffected. Direct substitution is supported for automotive circuit designs.

Q: What are the differences in reverse recovery time between these parts?

A: ES1ALHRUG specifies a reverse recovery time (trr) of 35 ns, while HS1AL RVG specifies 50 ns. Both meet the fast recovery classification (≤ 500ns, > 200mA). The 15 ns difference is negligible for most general-purpose rectification applications but becomes relevant in high-frequency switching circuits where minimizing switching losses is critical.

Q: Are the package dimensions identical between ES1ALHRUG and HS1AL RVG?

A: Yes. Both parts use the DO-219AB Sub SMA surface mount package format with identical mechanical specifications. PCB footprints, solder pad layouts, and mounting procedures are identical, enabling direct board-level substitution without design modifications.

Q: What is the significance of the junction capacitance difference?

A: ES1ALHRUG specifies 10 pF junction capacitance while HS1AL RVG specifies 20 pF, both measured at 4 V and 1 MHz. For general-purpose rectification applications, this difference is typically insignificant. High-frequency circuits or applications with stringent capacitance requirements should specify ES1ALHRUG to minimize parasitic effects.

Q: Do both parts require identical moisture handling procedures?

A: Yes. Both parts carry Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling procedures for surface mount components apply equally to both parts.

Q: Which part should be selected for new designs?

A: Selection depends on application-specific requirements. For general-purpose rectification with standard performance requirements, either part is suitable. For high-frequency applications or designs sensitive to switching losses, ES1ALHRUG is preferred due to faster reverse recovery time. For applications prioritizing inventory availability, HS1AL RVG offers higher stock levels.
