ES1JLHMHG Equivalent & Substitute Parts

Part Overview

The ES1JLHMHG is a general-purpose rectifier diode rated for 600 V DC reverse voltage and 1 A average rectified current in a Sub SMA surface mount package. Manufactured by Taiwan Semiconductor Corporation, this component is classified as Active product status and carries AEC-Q101 automotive qualification. The device exhibits fast recovery characteristics with a reverse recovery time of 35 ns, making it suitable for applications requiring rapid switching performance.

Substitute parts become necessary when the primary part number reaches end-of-life status, inventory constraints occur, or design flexibility is required across manufacturing locations. The ES1JL variant carries a Not For New Designs status, while the HS1JL RVG maintains Active status, providing alternative sourcing options with equivalent electrical performance within specified parameter tolerances.

Substitute Part Grouping Explanation

Substitution eligibility for rectifier diodes is determined by equivalence across the following critical parameters:

Voltage Rating: All substitute parts must maintain the 600 V DC reverse voltage specification to ensure safe operation within the intended circuit application.

Current Rating: The 1 A average rectified current specification must be matched or exceeded by substitute components.

Package and Mounting: All qualified substitutes utilize the DO-219AB package with Sub SMA supplier device package designation and surface mount mounting type, ensuring mechanical and electrical compatibility with existing PCB designs.

Forward Voltage Drop: The maximum forward voltage of 1.7 V at 1 A must be maintained to preserve circuit performance and power dissipation characteristics.

Reverse Recovery Time: Fast recovery operation with reverse recovery time specifications of 35 ns or 75 ns falls within acceptable fast recovery classification (≤500 ns, >200 mA).

Reverse Leakage Current: The 5 µA maximum reverse leakage current at 600 V is consistent across all qualified substitutes.

Compliance and Qualification: RoHS3 compliance, REACH unaffected status, and AEC-Q101 automotive qualification are maintained across the substitute parts listed.

Engineering Selection Recommendations

ES1JL: This part number provides parametric equivalence to the ES1JLHMHG across all critical electrical specifications, including voltage rating, current capacity, forward voltage drop, and reverse recovery time. However, ES1JL carries a Not For New Designs product status designation. This classification indicates the part is available for existing design support and replacement applications but is not recommended for new product development initiatives. Selection of ES1JL is appropriate for sustaining engineering, field replacements, and legacy system maintenance where design continuity is required.

HS1JL RVG: This substitute maintains Active product status and provides full parametric equivalence in voltage rating, current capacity, forward voltage drop, and reverse leakage current. The reverse recovery time specification of 75 ns differs from the primary part's 35 ns, representing a slower recovery characteristic within the fast recovery classification. The junction capacitance is specified at 15 pF compared to 8 pF for the primary part. HS1JL RVG is suitable for new designs and ongoing production applications, offering long-term availability and active manufacturer support. This part is the preferred substitute when design flexibility permits the specified parameter variations.

Both substitute parts maintain identical compliance certifications including RoHS3, REACH unaffected status, and AEC-Q101 automotive qualification, ensuring regulatory and quality requirements are satisfied across all three part numbers.

Frequently Asked Questions (FAQ)

Q: Can ES1JL be used as a direct replacement for ES1JLHMHG in new product designs?

A: ES1JL provides electrical equivalence but carries Not For New Designs status. For new product development, HS1JL RVG is the appropriate substitute, as it maintains Active product status and full manufacturer support.

Q: What is the significance of the reverse recovery time difference between ES1JLHMHG (35 ns) and HS1JL RVG (75 ns)?

A: Both parts are classified as fast recovery diodes with reverse recovery time specifications within the ≤500 ns, >200 mA range. The 35 ns specification of ES1JLHMHG represents faster switching performance. HS1JL RVG at 75 ns remains within fast recovery classification and is suitable for applications where the slower recovery time does not compromise circuit performance. Circuit-specific switching frequency and load requirements determine whether this parameter difference is acceptable.

Q: Does the capacitance difference between ES1JLHMHG (8 pF) and HS1JL RVG (15 pF) affect circuit compatibility?

A: The capacitance specification at 4 V and 1 MHz differs between the parts. HS1JL RVG exhibits higher junction capacitance. This parameter affects high-frequency circuit behavior and switching transients. Compatibility depends on circuit design margins and operating frequency. Applications with stringent capacitance requirements should retain ES1JLHMHG or ES1JL.

Q: Are all three part numbers available in identical packaging?

A: All three parts utilize DO-219AB package with Sub SMA supplier device package designation and surface mount mounting type. PCB footprints and assembly processes are identical across ES1JLHMHG, ES1JL, and HS1JL RVG.

Q: What compliance certifications apply to these substitute parts?

A: All three part numbers maintain RoHS3 compliance, REACH unaffected status, AEC-Q101 automotive qualification, and identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Q: What is the inventory status of each part number?

A: ES1JLHMHG maintains 898 pieces in stock. ES1JL provides significantly higher availability at 84,500 pieces. HS1JL RVG is available with 1,030 pieces in stock. Inventory levels should be verified at time of procurement.
