ES1JLHRFG Equivalent & Substitute Parts

Part Overview

The ES1JLHRFG 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. This component is classified as Active product status and meets AEC-Q101 automotive qualification standards. The ES1JLHRFG is manufactured by Taiwan Semiconductor Corporation and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts become necessary when the primary part number reaches end-of-life status, inventory constraints occur, or design revisions require alternative qualified sources. The ES1JL variant carries a Not For New Designs status, making it suitable only for legacy system support. The HS1JL RVG maintains Active status and serves as a direct functional alternative for new designs.

Substitute Part Grouping Explanation

Substitution eligibility for the ES1JLHRFG is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

Voltage - DC Reverse (Vr) (Max): 600 V
Current - Average Rectified (Io): 1 A
Voltage - Forward (Vf) (Max) @ If: 1.7 V @ 1 A
Package / Case: DO-219AB
Mounting Type: Surface Mount
Operating Temperature - Junction: -55°C to 150°C

Allowable Variation Parameters:

Reverse Recovery Time (trr): Permitted to vary within fast recovery classification
Capacitance @ Vr, F: Permitted to vary within specified frequency and voltage conditions
Current - Reverse Leakage @ Vr: Permitted to remain at or below specified maximum

All substitute parts listed maintain identical voltage, current, and thermal ratings. Variations in recovery time and capacitance remain within acceptable operating margins for general-purpose rectification applications.

Engineering Selection Recommendations

For Active Product Designs: The HS1JL RVG is the preferred substitute for new designs. This part maintains Active product status and meets all mandatory electrical and thermal specifications. The HS1JL RVG exhibits a longer reverse recovery time (75 ns versus 35 ns) and higher capacitance (15 pF versus 8 pF), which remain within acceptable operating parameters for general-purpose rectification. Both the ES1JLHRFG and HS1JL RVG carry AEC-Q101 automotive qualification and ROHS3 compliance.

For Legacy System Support: The ES1JL is available for maintenance and repair of existing systems. This part carries Not For New Designs status and should not be selected for new product development. The ES1JL maintains identical electrical specifications to the ES1JLHRFG, including 35 ns reverse recovery time and 8 pF capacitance.

Compliance Considerations: All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. All parts are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Frequently Asked Questions (FAQ)

Q: Can the ES1JL be used in new product designs? A: No. The ES1JL carries Not For New Designs status. New designs must use either the ES1JLHRFG or HS1JL RVG, both of which maintain Active product status.

Q: What is the difference between the ES1JLHRFG and HS1JL RVG? A: Both parts meet identical voltage (600 V), current (1 A), and forward voltage (1.7 V @ 1 A) specifications. The HS1JL RVG has a longer reverse recovery time (75 ns versus 35 ns) and higher capacitance (15 pF versus 8 pF). These differences remain within acceptable operating margins for general-purpose rectification applications.

Q: Are all substitute parts in the same package? A: Yes. All three parts use the DO-219AB package with Sub SMA supplier device package designation and surface mount mounting type.

Q: Do all parts meet automotive qualification requirements? A: The ES1JLHRFG and HS1JL RVG both carry AEC-Q101 automotive qualification. The ES1JL does not list AEC-Q101 qualification in the provided specifications.

Q: What is the operating temperature range for these diodes? A: All three parts operate across a junction temperature range of -55°C to 150°C.

Q: Are these parts RoHS compliant? A: Yes. All three parts are ROHS3 compliant and REACH unaffected.

Q: What is the moisture sensitivity level for these components? A: All three parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: Can the ES1JLHRFG be directly replaced with the HS1JL RVG on existing PCBs? A: Yes. Both parts use identical DO-219AB packaging and surface mount mounting type, allowing direct PCB replacement without layout modifications.
