ES1BLHM2G Equivalent & Substitute Parts

Part Overview

The ES1BLHM2G 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 Sub SMA (DO-219AB) surface mount configuration. The part carries Active product status and meets automotive-grade specifications with AEC-Q101 qualification.

Equivalent and substitute parts become necessary when the primary part number reaches end-of-life status, inventory constraints occur, or when design flexibility is required across manufacturing locations. The ES1BLHM2G maintains full compatibility with identified substitute part numbers that share identical electrical and mechanical parameters within the allowed specification range.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ES1BLHM2G is determined by strict equivalence across the following critical parameters:

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

Mechanical Parameters (Must Match Exactly):

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

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• Grade: Automotive
• Qualification: AEC-Q101

The identified substitute parts ES1BL and ES1BLH meet all electrical and mechanical parameter requirements. Both parts are manufactured by Taiwan Semiconductor Corporation and maintain identical electrical performance characteristics. The primary distinction between substitute parts relates to product status and packaging format (Tape & Reel), not functional equivalence.

Engineering Selection Recommendations

ES1BLHM2G (Primary Selection)

The ES1BLHM2G is the recommended selection for new designs. This part carries Active product status, indicating full manufacturer support and continued availability. It meets automotive-grade specifications with AEC-Q101 qualification and maintains ROHS3 compliance. The part is currently in stock with 855 pieces available.

ES1BLH (Preferred Substitute)

The ES1BLH is the preferred substitute option when ES1BLHM2G availability is constrained. This part maintains identical electrical and mechanical parameters, automotive-grade classification, and AEC-Q101 qualification. Although marked as Not For New Designs, it remains functionally equivalent for existing designs requiring component replacement or alternative sourcing. Inventory availability is 37,063 pieces. The primary distinction is packaging format (Tape & Reel) rather than functional performance.

ES1BL (Secondary Substitute)

The ES1BL is a secondary substitute option when ES1BLH is unavailable. This part matches all electrical and mechanical parameters and maintains ROHS3 compliance. However, it lacks automotive-grade designation and AEC-Q101 qualification. Use of ES1BL is restricted to non-automotive applications or situations where automotive qualification is not required. Product status is Not For New Designs. Inventory availability is 18,860 pieces.

Frequently Asked Questions (FAQ)

Q: Can ES1BL be used as a direct replacement for ES1BLHM2G in automotive applications?

A: No. The ES1BL does not carry automotive-grade classification or AEC-Q101 qualification. For automotive applications, use ES1BLH, which maintains both automotive-grade status and AEC-Q101 qualification identical to the ES1BLHM2G.

Q: What is the difference between ES1BLHM2G and ES1BLH?

A: Both parts are electrically and mechanically identical, with matching voltage ratings (100 V), current ratings (1 A), forward voltage (950 mV @ 1 A), and reverse recovery time (35 ns). Both carry automotive-grade classification and AEC-Q101 qualification. The primary difference is product status: ES1BLHM2G is Active, while ES1BLH is Not For New Designs. Packaging format also differs (ES1BLHM2G is individual packaging; ES1BLH is Tape & Reel).

Q: Are all substitute parts in the same package?

A: Yes. All three parts (ES1BLHM2G, ES1BL, and ES1BLH) use the DO-219AB package in Sub SMA configuration with surface mount mounting type. They are mechanically interchangeable on PCB layouts designed for this package.

Q: What compliance certifications apply to each part?

A: ES1BLHM2G and ES1BLH both carry ROHS3 compliance, AEC-Q101 qualification, and automotive-grade classification. ES1BL carries ROHS3 compliance but lacks automotive-grade designation and AEC-Q101 qualification.

Q: Can I use ES1BL in a design originally specified for ES1BLHM2G?

A: Only if the application does not require automotive-grade components or AEC-Q101 qualification. If automotive specifications are mandatory, use ES1BLH instead.

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

A: All three parts operate across a junction temperature range of -55°C to 150°C, providing identical thermal performance characteristics.

Q: Are there any differences in electrical performance between the substitute parts?

A: No. All three parts deliver identical electrical performance: 100 V reverse voltage rating, 1 A average rectified current, 950 mV forward voltage at 1 A, 35 nanosecond reverse recovery time, 5 µA reverse leakage current at 100 V, and 10 pF capacitance at 4 V and 1 MHz.
