ES1DLHMQG Equivalent & Substitute Parts

Part Overview

The ES1DLHMQG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 200 V DC reverse voltage and 1 A average rectified current. This surface mount component operates in the Sub SMA package (DO-219AB) and is classified as a fast recovery diode with a reverse recovery time of 35 nanoseconds. The part is Active in product status, RoHS3 compliant, and qualified to AEC-Q101 automotive standards.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter set. Alternative part numbers may be required due to inventory availability, packaging format differences, or specific application requirements while maintaining functional equivalence.

Substitute Part Grouping Explanation

Substitution eligibility for the ES1DLHMQG is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 1 A
• Package / Case: DO-219AB (Sub SMA)
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant
• Product Status: Active

Allowable Variation Parameters:

• Reverse Recovery Time (trr): Faster or equal performance acceptable
• Voltage - Forward (Vf) (Max): Equal or lower acceptable
• Current - Reverse Leakage @ Vr: Equal or lower acceptable
• Capacitance @ Vr, F: Variation acceptable within application tolerance
• Packaging Format: Cut Tape (CT), Digi-Reel®, or equivalent distribution formats

The ES1DL and HS1DL RVG meet these substitution criteria with identical or superior electrical characteristics while maintaining full mechanical and thermal compatibility.

Parameter Comparison

Engineering Selection Recommendations

ES1DL Substitution: The ES1DL is a direct parametric equivalent to the ES1DLHMQG with identical electrical specifications across all critical parameters. Both parts share the same base product number (ES1D), reverse recovery time (35 ns), and forward voltage characteristics. The ES1DL differs only in packaging format availability (Cut Tape and Digi-Reel® options) and higher inventory availability (9534 units in stock). This part is suitable for direct substitution in all applications where the ES1DLHMQG is specified.

HS1DL RVG Substitution: The HS1DL RVG maintains voltage, current, and thermal specifications identical to the ES1DLHMQG. The reverse recovery time is 50 nanoseconds (versus 35 nanoseconds for the main part) and capacitance is 20 pF (versus 10 pF). These parameters represent acceptable performance variations for general-purpose rectification applications. The HS1DL RVG is qualified to the same AEC-Q101 automotive standard and RoHS3 compliance. This part is suitable for substitution in applications where the slightly longer recovery time and increased capacitance do not impose circuit constraints.

Both substitute parts maintain Active product status, full regulatory compliance, and identical thermal operating ranges. Selection between ES1DL and HS1DL RVG should be based on packaging format requirements and specific circuit timing or capacitance tolerances.

Frequently Asked Questions (FAQ)

Q: Can ES1DL be used as a direct replacement for ES1DLHMQG?

A: Yes. The ES1DL is a parametric equivalent with identical voltage rating (200 V), current rating (1 A), forward voltage (950 mV @ 1 A), reverse recovery time (35 ns), and reverse leakage current (5 µA @ 200 V). Both parts use the DO-219AB Sub SMA package and operate across the same temperature range (-55°C to 150°C). The only difference is packaging format availability.

Q: What are the differences between ES1DL and HS1DL RVG?

A: Both parts meet the 200 V, 1 A specifications and use identical packaging. The HS1DL RVG has a reverse recovery time of 50 nanoseconds (compared to 35 ns for ES1DL) and capacitance of 20 pF at 4V, 1MHz (compared to 10 pF for ES1DL). These differences are acceptable for general-purpose rectification but may affect performance in high-frequency switching applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The ES1DLHMQG, ES1DL, and HS1DL RVG are all ROHS3 compliant with MSL rating of 1 (Unlimited) and REACH Unaffected status.

Q: What is the significance of the DO-219AB package designation?

A: DO-219AB is the industry standard package designation for Sub SMA surface mount diodes. All three parts (ES1DLHMQG, ES1DL, and HS1DL RVG) use this identical package, ensuring mechanical and thermal compatibility in PCB layouts and reflow processes.

Q: Can HS1DL RVG be used in applications requiring 35 nanosecond recovery time?

A: No. The HS1DL RVG has a reverse recovery time of 50 nanoseconds. Applications with strict timing requirements for 35 nanosecond recovery must use ES1DLHMQG or ES1DL.

Q: What is the difference between Cut Tape and Digi-Reel® packaging formats?

A: Both are surface mount packaging formats for automated assembly. Cut Tape (CT) provides components on individual tape segments, while Digi-Reel® is a continuous reel format. Both formats are compatible with standard pick-and-place equipment. Format selection depends on production volume and assembly line configuration.

Q: Are all substitute parts qualified to AEC-Q101?

A: The ES1DLHMQG is explicitly qualified to AEC-Q101 automotive standards. The ES1DL and HS1DL RVG specifications provided do not explicitly state AEC-Q101 qualification status. Verification of automotive qualification should be confirmed with the manufacturer for applications requiring AEC-Q101 compliance.
