ES1GLHM2G Equivalent & Substitute Parts

Part Overview

The ES1GLHM2G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 400 V DC reverse voltage and 1 A average rectified current. This component is packaged in the Sub SMA (DO-219AB) surface mount configuration and is classified as Active product status with AEC-Q101 automotive qualification.

Substitute parts are necessary when the ES1GLHM2G reaches end-of-life status, when alternative packaging formats are required for manufacturing processes, or when inventory constraints necessitate sourcing from available alternatives that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ES1GLHM2G is determined by the following critical parameters:

Mandatory Matching 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
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Variation Parameters:

• Reverse Recovery Time (trr): Values up to 50 ns are acceptable
• Capacitance @ Vr, F: Values up to 15 pF are acceptable
• Packaging Format: Cut Tape (CT), Digi-Reel®, or Tape & Reel (TR) formats are interchangeable
• Product Status: Active or Not For New Designs variants are functionally equivalent

The three identified substitute parts (ES1GL, ES1GL RVG, and HS1GL RVG) meet all mandatory matching parameters and fall within allowable variation ranges for recovery time and capacitance characteristics.

Parameter Comparison

Engineering Selection Recommendations

ES1GL RVG is the primary substitute for ES1GLHM2G. Both components share identical electrical specifications and are classified as Active product status. The ES1GL RVG is supplied in Tape & Reel (TR) packaging format, which is standard for high-volume surface mount assembly operations. Current inventory of 4,619 pieces supports immediate procurement.

HS1GL RVG is a secondary substitute option. This component maintains all critical electrical parameters with the exception of reverse recovery time (50 ns versus 35 ns) and capacitance (15 pF versus 8 pF). These variations remain within acceptable operational ranges for general-purpose rectification applications. The HS1GL RVG is Active product status with higher inventory availability (18,316 pieces).

ES1GL is available as a tertiary option in Cut Tape (CT) and Digi-Reel® packaging formats. This part is classified as Not For New Designs, indicating it is suitable for replacement and maintenance applications but not recommended for new product development. Inventory of 95,300 pieces provides substantial availability.

All three substitute parts maintain ROHS3 compliance, AEC-Q101 automotive qualification standards, and identical moisture sensitivity ratings. Selection between these options should be based on packaging format requirements, product status constraints for new designs, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can ES1GL RVG directly replace ES1GLHM2G in existing designs?

A: Yes. ES1GL RVG meets all mandatory electrical parameters: 400 V reverse voltage, 1 A average rectified current, 1.3 V forward voltage at 1 A, and identical operating temperature range. Both components use DO-219AB surface mount packaging. The primary difference is packaging format (Tape & Reel versus the original format), which does not affect electrical performance.

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

A: Both parts meet the core electrical requirements of 400 V, 1 A, and 1.3 V forward voltage. HS1GL RVG has a reverse recovery time of 50 ns compared to 35 ns for ES1GL RVG, and capacitance of 15 pF compared to 8 pF. These differences are within acceptable ranges for general-purpose rectification but may affect performance in high-frequency switching applications.

Q: Why is ES1GL marked as "Not For New Designs"?

A: Product status designations indicate manufacturer recommendations for design phases. "Not For New Designs" means the part is suitable for replacement, repair, and maintenance of existing products but should not be selected for new product development. ES1GL remains electrically and mechanically compatible with ES1GLHM2G.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. ES1GL, ES1GL RVG, and HS1GL RVG are all ROHS3 compliant with MSL rating of 1 (Unlimited). All parts meet REACH requirements and carry identical environmental compliance certifications.

Q: Does packaging format affect electrical performance?

A: No. Cut Tape (CT), Digi-Reel®, and Tape & Reel (TR) packaging formats are supply chain variations only. The electrical and mechanical specifications of the diode component remain identical regardless of packaging format. Selection should be based on assembly equipment compatibility and procurement requirements.

Q: Can HS1GL RVG be used in automotive applications?

A: Yes. HS1GL RVG carries AEC-Q101 automotive qualification, identical to ES1GLHM2G. The higher reverse recovery time and capacitance do not disqualify it from automotive use but should be evaluated against specific circuit requirements.
