ES1BLHMHG Equivalent & Substitute Parts

Part Overview

The ES1BLHMHG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 100 V DC reverse voltage and 1 A average rectified current. This component is classified as a fast recovery diode with a reverse recovery time of 35 nanoseconds, packaged in the DO-219AB (Sub SMA) surface mount configuration. The part is Active product status and carries automotive-grade qualification under AEC-Q101 standard.

Substitute parts become necessary when the primary part number reaches end-of-life status, inventory constraints occur, or design revisions require alternative sourcing. The ES1BLHMHG maintains full electrical and mechanical compatibility with identified substitute part numbers that share identical electrical specifications and packaging requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the ES1BLHMHG is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 950 mV @ 1 A
• Reverse Recovery Time (trr): 35 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 100 V
• Capacitance @ Vr, F: 10 pF @ 4V, 1MHz

Mechanical & Environmental Specifications:

• Package / Case: DO-219AB (Sub SMA)
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Compliance & Certification:

• RoHS Status: ROHS3 Compliant
• Grade: Automotive
• Qualification: AEC-Q101

Substitute parts ES1BL and ES1BLH meet all electrical and mechanical parameters. Both are manufactured by Taiwan Semiconductor Corporation and maintain identical electrical performance characteristics. The primary distinction between substitute candidates relates to product status and packaging format, not electrical or functional capability.

Engineering Selection Recommendations

ES1BLHMHG (Primary Selection)

The ES1BLHMHG is the recommended selection for new designs. This part carries Active product status, indicating ongoing manufacturer support and availability. It maintains full automotive-grade qualification under AEC-Q101 standard and is ROHS3 compliant. Current inventory of 1,093 pieces supports immediate procurement requirements.

ES1BLH (Preferred Substitute)

The ES1BLH is the primary substitute candidate. This part maintains identical electrical specifications and mechanical packaging to the ES1BLHMHG. Critically, ES1BLH retains automotive-grade qualification and AEC-Q101 certification, ensuring compliance with automotive application requirements. The part is marked "Not For New Designs" but remains suitable for replacement, repair, and legacy system applications. Inventory availability of 37,063 pieces provides robust supply assurance.

ES1BL (Secondary Substitute)

The ES1BL is a secondary substitute option. While it maintains identical electrical specifications and DO-219AB packaging, this part does not carry automotive-grade designation or AEC-Q101 qualification. The ES1BL is marked "Not For New Designs" and lacks the automotive certifications present in the primary part. This substitute is suitable only for non-automotive applications or where automotive qualification is not a design requirement. Inventory of 18,860 pieces is available.

Selection Criteria Summary

For automotive applications requiring AEC-Q101 compliance, select ES1BLHMHG (Active) or ES1BLH (substitute). For non-automotive applications, ES1BL is electrically equivalent. All three parts share identical electrical performance and DO-219AB surface mount packaging.

Frequently Asked Questions (FAQ)

Q: Can ES1BL be used as a direct replacement for ES1BLHMHG in automotive applications?

A: No. The ES1BL lacks automotive-grade designation and AEC-Q101 qualification. For automotive applications, use ES1BLHMHG (Active) or ES1BLH (substitute). The ES1BL is suitable only for non-automotive applications.

Q: Are ES1BLH and ES1BLHMHG electrically identical?

A: Yes. Both parts share identical electrical specifications: 100 V reverse voltage, 1 A average rectified current, 950 mV forward voltage at 1 A, 35 ns reverse recovery time, and 5 µA reverse leakage current at 100 V. Both maintain automotive-grade qualification and AEC-Q101 certification.

Q: What is the difference between ES1BL and ES1BLH?

A: The primary difference is automotive qualification. ES1BLH carries automotive-grade designation and AEC-Q101 certification; ES1BL does not. Electrically, both parts are identical. Both are marked "Not For New Designs."

Q: Can these diodes be used interchangeably in PCB assembly?

A: Yes, for electrical and mechanical purposes. All three parts use identical DO-219AB (Sub SMA) surface mount packaging and mounting type. PCB layout and assembly processes require no modification. However, automotive application requirements must be considered when selecting between qualified and non-qualified variants.

Q: What is the significance of "Not For New Designs" status?

A: This designation indicates the manufacturer is not recommending these parts for new product development. However, these parts remain suitable for replacement, repair, and legacy system applications where the part is already in use. The ES1BLHMHG (Active status) is the recommended selection for new designs.

Q: Are all three parts ROHS3 compliant?

A: Yes. ES1BLHMHG, ES1BL, and ES1BLH are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the reverse recovery time specification, and why is it important?

A: Reverse recovery time (trr) is 35 nanoseconds for all three parts. This specification indicates the time required for the diode to switch from forward conduction to reverse blocking. Fast recovery characteristics (≤500 ns) are critical for switching power supply applications and high-frequency rectification circuits.

Q: Can these diodes operate across the full temperature range in automotive environments?

A: Yes. All three parts are rated for junction operating temperatures from -55°C to 150°C, supporting automotive environmental requirements including extreme temperature conditions.
