ES1GLHMTG Equivalent & Substitute Parts

Part Overview

The ES1GLHMTG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 400 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.

Substitute parts are necessary when the ES1GLHMTG becomes unavailable due to inventory constraints, supply chain disruptions, or when alternative packaging formats are required for manufacturing processes. The substitute parts listed maintain electrical equivalence across critical parameters while offering different packaging and availability options.

Substitute Part Grouping Explanation

Substitution of the ES1GLHMTG is determined by strict equivalence across the following critical electrical parameters:

Voltage - DC Reverse (Vr) (Max): 400 V
Current - Average Rectified (Io): 1 A
Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1 A
Package / Case: DO-219AB (Sub SMA)
Mounting Type: Surface Mount
Operating Temperature Range: -55°C to 150°C
RoHS Compliance: ROHS3 Compliant

The substitute parts ES1GL, ES1GL RVG, and HS1GL RVG maintain these core electrical specifications. Variations in packaging format (Cut Tape, Tape & Reel) and minor differences in secondary parameters (reverse recovery time, capacitance) do not affect functional equivalence in standard applications. The HS1GL RVG exhibits a reverse recovery time of 50 ns (versus 35 ns for ES1GLHMTG) and capacitance of 15 pF (versus 8 pF), representing acceptable parametric variance within the fast recovery diode classification.

Engineering Selection Recommendations

Primary Selection: ES1GL RVG

The ES1GL RVG is the preferred substitute for the ES1GLHMTG. Both components maintain Active product status, ensuring continued manufacturer support and supply availability. The ES1GL RVG is supplied in Tape & Reel (TR) format with 4,619 units in stock. Electrical parameters are identical to the main part, including reverse recovery time of 35 ns and capacitance of 8 pF. This part is suitable for new designs and production applications.

Secondary Selection: HS1GL RVG

The HS1GL RVG is an acceptable substitute with Active product status and higher inventory availability (18,316 units in stock). This part exhibits a reverse recovery time of 50 ns and capacitance of 15 pF, representing minor parametric variance from the ES1GLHMTG. The HS1GL RVG is appropriate for applications where the extended reverse recovery time and increased capacitance do not impose circuit performance constraints.

Alternative Selection: ES1GL

The ES1GL is electrically equivalent to the ES1GLHMTG with identical electrical specifications. However, this part carries a "Not For New Designs" product status designation. The ES1GL is available in Cut Tape (CT) and Digi-Reel® packaging formats with substantial inventory (95,300 units in stock). This part is suitable only for replacement, repair, or legacy system applications where new design qualification is not required.

All substitute parts comply with ROHS3 standards, maintain the DO-219AB package specification, and operate across the -55°C to 150°C junction temperature range.

Frequently Asked Questions (FAQ)

Q: Can ES1GL RVG be used as a direct replacement for ES1GLHMTG in new designs?

A: Yes. The ES1GL RVG maintains identical electrical specifications across all critical parameters: 400 V reverse voltage, 1 A average rectified current, 1.3 V forward voltage, and 35 ns reverse recovery time. Both components are Active product status and ROHS3 compliant. The primary difference is packaging format (Tape & Reel versus the original specification).

Q: What is the difference between ES1GL and ES1GL RVG?

A: Both parts are electrically identical with 400 V, 1 A ratings and identical electrical characteristics. The primary differences are packaging format and product status. ES1GL is supplied in Cut Tape (CT) and Digi-Reel® formats with "Not For New Designs" status, while ES1GL RVG is supplied in Tape & Reel (TR) format with Active status.

Q: Is HS1GL RVG a suitable substitute despite the 50 ns reverse recovery time?

A: The HS1GL RVG is a suitable substitute for applications where the 50 ns reverse recovery time (versus 35 ns for ES1GLHMTG) and 15 pF capacitance (versus 8 pF) do not create circuit performance issues. Both parts maintain the 400 V, 1 A electrical ratings and are classified as fast recovery diodes. Circuit-level analysis is required to confirm compatibility in timing-sensitive applications.

Q: Are all substitute parts available in the same package?

A: Yes. All substitute parts use the DO-219AB package (Sub SMA) with surface mount mounting type. Differences exist only in packaging format: ES1GLHMTG is specified with no packaging format designation, ES1GL is available in Cut Tape and Digi-Reel® formats, while ES1GL RVG and HS1GL RVG are supplied in Tape & Reel format.

Q: Which substitute part has the best inventory availability?

A: The ES1GL has the highest inventory availability with 95,300 units in stock. However, this part carries "Not For New Designs" status. For new designs, ES1GL RVG (4,619 units) and HS1GL RVG (18,316 units) are both Active status alternatives, with HS1GL RVG offering superior availability.

Q: Do all substitute parts meet automotive qualification standards?

A: The ES1GLHMTG carries AEC-Q101 automotive qualification. The substitute parts provided do not explicitly list AEC-Q101 qualification in the input parameters. Automotive application requirements must be confirmed with the manufacturer before substitution in qualified designs.
