ES1BLHRUG Equivalent & Substitute Parts

Part Overview

The ES1BLHRUG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, classified as a fast recovery diode in the Sub SMA package (DO-219AB). This component is designed for surface mount applications requiring 100 V reverse voltage rating and 1 A average rectified current capacity. The part is currently in Active product status with AEC-Q101 automotive qualification and ROHS3 compliance.

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 ES1BLHRUG maintains full parametric equivalence with identified substitute part numbers ES1BL and ES1BLH, which share identical electrical characteristics and mechanical compatibility within the specified operating envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ES1BLHRUG is determined by strict parametric matching across all critical electrical and mechanical specifications. The following parameters establish the substitution criteria:

Electrical Parameters (Must Match Exactly):

• 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
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameters (Must Match Exactly):

• Package / Case: DO-219AB
• Supplier Device Package: Sub SMA
• Mounting Type: Surface Mount

Environmental & Compliance Parameters:

• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Both identified substitute parts (ES1BL and ES1BLH) satisfy all parametric equivalence requirements. The ES1BLH additionally maintains Automotive Grade classification and AEC-Q101 qualification, matching the primary part's automotive credentials.

Engineering Selection Recommendations

Primary Selection: ES1BLHRUG

The ES1BLHRUG is the recommended selection for new designs. This part maintains Active product status, ensuring long-term availability and manufacturing support. It carries Automotive Grade classification with AEC-Q101 qualification, meeting stringent automotive reliability standards. The part is ROHS3 compliant and REACH unaffected, satisfying current environmental regulations.

Secondary Selection: ES1BLH

The ES1BLH serves as the preferred substitute when ES1BLHRUG availability is constrained. Although designated as Not For New Designs, this part maintains identical electrical and mechanical parameters with full Automotive Grade and AEC-Q101 qualification. It is suitable for replacement applications, design revisions, and inventory supplementation in existing production lines. The ES1BLH offers significantly higher inventory availability (37,063 pcs) compared to the primary part.

Tertiary Selection: ES1BL

The ES1BL is available as a secondary substitute when both ES1BLHRUG and ES1BLH are unavailable. This part satisfies all parametric equivalence requirements and maintains ROHS3 compliance and REACH unaffected status. However, ES1BL lacks Automotive Grade classification and AEC-Q101 qualification. This part is designated Not For New Designs and is suitable only for non-automotive applications or as a temporary supply solution in non-critical applications where automotive qualification is not required.

All three parts share identical electrical performance, mechanical compatibility, and thermal operating range. Selection between substitutes should be based on product status requirements, automotive qualification necessity, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can ES1BL be used as a direct replacement for ES1BLHRUG in automotive applications?

A: No. While ES1BL maintains identical electrical and mechanical parameters, it lacks Automotive Grade classification and AEC-Q101 qualification. Automotive applications require the ES1BLHRUG or ES1BLH, both of which carry AEC-Q101 qualification.

Q: What is the difference between ES1BLHRUG and ES1BLH?

A: Both parts are electrically and mechanically identical with matching 100 V reverse voltage, 1 A current rating, 35 ns reverse recovery time, and DO-219AB Sub SMA packaging. The primary difference is product status: ES1BLHRUG is Active, while ES1BLH is Not For New Designs. Both maintain Automotive Grade and AEC-Q101 qualification.

Q: Are all three substitute parts compatible with the same PCB layout?

A: Yes. All three parts (ES1BLHRUG, ES1BL, and ES1BLH) use identical DO-219AB Sub SMA packaging with Surface Mount mounting type. PCB footprints and assembly processes are interchangeable.

Q: What does "Not For New Designs" status mean for ES1BL and ES1BLH?

A: This designation indicates the manufacturer does not recommend these parts for new product development. However, they remain available for replacement, repair, and existing production support. These parts are suitable for sustaining engineering and inventory supplementation.

Q: Can I substitute ES1BL for ES1BLHRUG in a design that does not require automotive qualification?

A: Yes. For non-automotive applications where AEC-Q101 qualification is not a requirement, ES1BL provides full parametric equivalence and is electrically and mechanically compatible. Verify that your application does not impose automotive or equivalent reliability standards.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by exact matching of: Voltage - DC Reverse (100 V), Current - Average Rectified (1 A), Voltage - Forward (950 mV @ 1 A), Reverse Recovery Time (35 ns), Current - Reverse Leakage (5 µA @ 100 V), Capacitance (10 pF @ 4V, 1MHz), Package (DO-219AB Sub SMA), and Operating Temperature Range (-55°C to 150°C).

Q: Are there any moisture sensitivity or handling differences between these parts?

A: No. All three parts carry Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions. Handling, storage, and assembly processes are identical across all three part numbers.

Q: Which substitute part should I select if both ES1BLHRUG and ES1BLH are unavailable?

A: Select ES1BL only if your application does not require Automotive Grade classification or AEC-Q101 qualification. Verify that your design specifications and end-use environment do not mandate automotive-level reliability standards before proceeding with ES1BL substitution.
