ES1GLHMHG Equivalent & Substitute Parts

Part Overview

The ES1GLHMHG 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 carries AEC-Q101 automotive qualification.

Substitute parts are necessary when the primary part number becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when inventory constraints necessitate sourcing from equivalent product variants within the same electrical and mechanical specifications.

Engineering Selection Recommendations

ES1GL RVG is the primary substitute for ES1GLHMHG. Both parts maintain identical electrical specifications, including reverse recovery time of 35 ns and capacitance of 8 pF. ES1GL RVG carries Active product status and is supplied in Tape & Reel packaging format. This part is suitable for new designs and production applications requiring the Sub SMA package configuration.

ES1GL is a parametric equivalent available in Cut Tape and Digi-Reel packaging formats. This part carries Not For New Designs product status and is not recommended for new circuit development. ES1GL is suitable only for replacement or maintenance applications where existing inventory must be replenished with identical electrical characteristics.

HS1GL RVG is a parametric equivalent with measurable differences in reverse recovery time (50 ns versus 35 ns) and capacitance (15 pF versus 8 pF). These variations remain within the fast recovery classification and do not alter the functional performance envelope. HS1GL RVG carries Active product status and is supplied in Tape & Reel packaging. Selection of HS1GL RVG is appropriate when ES1GL RVG availability is constrained, provided circuit design tolerates the specified parameter variations.

All substitute parts are ROHS3 compliant, carry MSL Level 1 (Unlimited) moisture sensitivity rating, and operate across the identical temperature range of -55°C to 150°C.

Frequently Asked Questions (FAQ)

Q: Can ES1GL be used as a direct replacement for ES1GLHMHG in new product designs?

A: No. ES1GL carries Not For New Designs product status. For new circuit development, use ES1GL RVG or HS1GL RVG, both of which carry Active product status.

Q: What is the difference between ES1GL RVG and HS1GL RVG?

A: Both parts meet the 400 V, 1 A electrical specification. ES1GL RVG has a reverse recovery time of 35 ns and capacitance of 8 pF. HS1GL RVG has a reverse recovery time of 50 ns and capacitance of 15 pF. Both remain within fast recovery classification. HS1GL RVG is suitable when ES1GL RVG is unavailable.

Q: What packaging formats are available for these substitute parts?

A: ES1GLHMHG is supplied in Sub SMA packaging (specific format not detailed). ES1GL is available in Cut Tape (CT) and Digi-Reel formats. ES1GL RVG and HS1GL RVG are supplied in Tape & Reel (TR) format. Packaging selection depends on manufacturing process requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. ES1GL, ES1GL RVG, and HS1GL RVG are all ROHS3 compliant and carry identical REACH Unaffected status.

Q: What is the moisture sensitivity level for these diodes?

A: All parts carry MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can HS1GL RVG be used in applications where ES1GL RVG is specified?

A: HS1GL RVG is electrically equivalent within the fast recovery classification. The 50 ns reverse recovery time and 15 pF capacitance are acceptable substitutes for the 35 ns and 8 pF specifications when circuit design margins accommodate these variations. Verification of circuit performance is the responsibility of the design engineer.

Q: What is the operating temperature range for these diodes?

A: All parts operate across a junction temperature range of -55°C to 150°C, suitable for automotive and industrial applications.
