Engineering Selection Recommendations

For Obsolete Part Replacement (ES1BE-TP):

The ES1BE-TP is classified as Obsolete. Direct replacement within the Micro Commercial Co product line is available through ES1B-LTP, which maintains identical electrical specifications (100 V, 1 A, fast recovery) with improved reverse recovery time (35 ns vs. 50 ns) and extended operating temperature range (-65°C to 175°C vs. -50°C to 150°C). ES1B-LTP is classified as Not For New Designs but remains available for legacy system support.

For New Design Implementation:

Active product status alternatives include:

ES1B-13-F (Diodes Incorporated): Maintains DO-214AC package compatibility with reduced forward voltage (920 mV vs. 975 mV) and faster recovery time (25 ns). Operating temperature range -55°C to 150°C matches the original specification envelope.
ES1B-E3/5AT and ES1B-E3/61T (Vishay General Semiconductor): Both offer identical electrical performance to ES1B-13-F with active product status and extended availability. Packaging is Cut Tape (CT) & Digi-Reel or standard tape formats.
ESH1B-E3/5AT (Vishay General Semiconductor): Provides superior reverse leakage performance (1 µA vs. 5 µA) with lowest forward voltage (900 mV) and extended temperature range (-55°C to 175°C). Suitable for applications requiring enhanced leakage specifications.
EGF1B-E3/5CA (Vishay General Semiconductor): Cross-manufacturer option using DO-214BA package (GF1 footprint) with active status. Electrically equivalent with extended temperature range and established supply chain.

For Cost-Optimized Selection:

CGRA4002-G (Comchip Technology) provides active product status with standard electrical specifications at competitive pricing. Forward voltage specification (1.1 V maximum) remains within acceptable tolerance for general-purpose rectification applications.

All recommended substitutes maintain RoHS3 compliance and MSL 1 rating. Package compatibility (DO-214AC vs. DO-214BA) must be verified against PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can ES1B-LTP directly replace ES1BE-TP in existing designs?

A: Yes. ES1B-LTP is electrically equivalent with identical voltage (100 V) and current (1 A) ratings. The primary differences are improved reverse recovery time (35 ns vs. 50 ns) and extended operating temperature range (-65°C to 175°C vs. -50°C to 150°C). Both use DO-214AC packaging. ES1B-LTP is classified as Not For New Designs but is suitable for legacy system support.

Q: What is the difference between DO-214AC and DO-214BA packages?

A: Both packages are surface mount rectifier packages with identical electrical performance and similar footprints. DO-214AC (SMA) and DO-214BA (GF1) are mechanically and electrically interchangeable for this application class. PCB layout compatibility must be confirmed with design documentation.

Q: Which substitute offers the lowest forward voltage drop?

A: ESH1B-E3/5AT provides the lowest forward voltage at 900 mV @ 1 A, compared to 975 mV for the original ES1BE-TP. This represents a 75 mV reduction, which may reduce power dissipation in high-current applications. ESH1B-E3/5AT also features the lowest reverse leakage current (1 µA vs. 5 µA).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original ES1BE-TP specification.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape (CT) and Tape & Reel (TR) refer to supply formats, not component specifications. Both formats contain identical components. Tape & Reel is suitable for automated assembly lines, while Cut Tape is used for manual or lower-volume applications. Electrical and thermal performance is identical.

Q: Can CGRA4002-G be used as a direct substitute despite higher forward voltage?

A: CGRA4002-G (1.1 V forward voltage) is electrically compatible for general-purpose rectification applications where the additional 125 mV forward voltage drop is acceptable. Applications sensitive to power dissipation or voltage regulation should use lower forward voltage alternatives such as ES1B-13-F (920 mV) or ESH1B-E3/5AT (900 mV).

Q: Which substitute has the fastest reverse recovery time?

A: ES1B-13-F, ES1B-E3/5AT, ES1B-E3/61T, and ESH1B-E3/5AT all feature 25 ns reverse recovery time, compared to 50 ns for the original ES1BE-TP. Faster recovery reduces switching losses in high-frequency applications.

Q: Is extended operating temperature range important for my application?

A: Extended temperature range (-65°C to 175°C) provided by EGF1B, EGF1B-E3/5CA, EGF1B-E3/67A, and ESH1B-E3/5AT is beneficial for industrial, automotive, or aerospace applications. Standard range (-55°C to 150°C) is sufficient for consumer and commercial electronics. Verify application requirements against thermal specifications.
