ES1BLHRVG Equivalent & Substitute Parts

Part Overview

The ES1BLHRVG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 100 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 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 ES1BL and ES1BLH variants provide electrical and mechanical equivalence while differing in product status and packaging configurations.

Substitute Part Grouping Explanation

Substitution of the ES1BLHRVG is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Parameters (Must Match):

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
Operating Temperature - Junction: -55°C to 150°C

Mechanical Parameters (Must Match):

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

Compliance Parameters (Must Match):

RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level (MSL): 1 (Unlimited)
REACH Status: REACH Unaffected

The ES1BL and ES1BLH variants satisfy all electrical and mechanical equivalence criteria. Differences in product status and packaging configuration (Tape & Reel versus bulk) do not affect functional substitution.

Engineering Selection Recommendations

ES1BLHRVG (Primary Selection): The ES1BLHRVG is the recommended selection for new designs. This part carries Active product status, indicating full manufacturer support and continued availability. It maintains automotive-grade qualification under AEC-Q101 standard and ROHS3 compliance, suitable for automotive and industrial applications requiring long-term supply assurance.

ES1BLH (Secondary Selection): The ES1BLH provides full electrical and mechanical equivalence to the ES1BLHRVG and retains automotive-grade qualification and AEC-Q101 certification. However, this part is designated as Not For New Designs, indicating limited future availability. The ES1BLH is suitable for legacy design support, field replacements, or applications where existing inventory must be utilized. Packaging is supplied in Tape & Reel configuration.

ES1BL (Tertiary Selection): The ES1BL satisfies all electrical and mechanical substitution criteria but lacks automotive-grade designation and AEC-Q101 qualification. This part is designated as Not For New Designs. The ES1BL is applicable only to non-automotive applications or situations where automotive qualification is not required. Packaging is supplied in Tape & Reel configuration.

Frequently Asked Questions (FAQ)

Q: Can ES1BL be used as a direct replacement for ES1BLHRVG in automotive applications?

A: No. The ES1BL does not carry automotive-grade qualification or AEC-Q101 certification. For automotive applications, only ES1BLHRVG or ES1BLH are acceptable substitutes.

Q: What is the difference between ES1BLHRVG and ES1BLH?

A: Both parts are electrically and mechanically identical with matching electrical parameters, package type (DO-219AB), and operating temperature range. The primary differences are product status (ES1BLHRVG is Active; ES1BLH is Not For New Designs) and packaging configuration (ES1BLHRVG is bulk; ES1BLH is Tape & Reel).

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

A: Yes. All three parts use the DO-219AB package in Sub SMA configuration with identical surface mount footprints and mounting requirements.

Q: Why is ES1BL marked as Not For New Designs?

A: This designation indicates the manufacturer is phasing out this part number. While it remains available, it is not recommended for new product designs due to uncertain long-term availability.

Q: Do all substitute parts meet RoHS and REACH compliance?

A: Yes. All three parts (ES1BLHRVG, ES1BL, and ES1BLH) are ROHS3 Compliant and REACH Unaffected.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

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

Q: Can ES1BLH be used in new automotive designs?

A: While ES1BLH carries automotive-grade qualification and AEC-Q101 certification, it is marked as Not For New Designs. For new automotive designs, ES1BLHRVG is the appropriate selection.
