Substitute Part Grouping Explanation

Substitute parts for the ES2EB-HF are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Voltage Rating: DC reverse voltage of 300V maximum
Current Rating: Average rectified current of 2A
Forward Voltage: Maximum 1.25V at 2A forward current
Recovery Characteristics: Fast recovery with reverse recovery time of 35ns
Package Compatibility: Surface mount SMB/DO-214AA package
Temperature Range: Operating junction temperature from -55°C to 150°C
Compliance: RoHS3 compliant status

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. Secondary parameters such as reverse leakage current and capacitance may vary within acceptable ranges without affecting primary circuit function.

Engineering Selection Recommendations

The ER2E_R1_00001 manufactured by Panjit International Inc. is a direct parametric equivalent to the ES2EB-HF. Both components share identical primary electrical specifications: 300V reverse voltage rating, 2A average rectified current, 1.25V forward voltage at 2A, and 35ns reverse recovery time. Both are packaged in the SMB/DO-214AA surface mount configuration and operate across the identical temperature range of -55°C to 150°C.

Both parts maintain RoHS3 compliance and are classified as Active product status. The ER2E_R1_00001 exhibits lower reverse leakage current (1µA versus 5µA at 300V) and lower junction capacitance (25pF versus 40pF at 4V, 1MHz), which represent performance improvements in leakage and high-frequency characteristics. These differences do not restrict substitution and may provide benefits in specific circuit applications.

Selection between these parts should be based on availability, lead time, cost considerations, and established supplier relationships. Both components are suitable for direct replacement in applications designed for the ES2EB-HF.

Frequently Asked Questions (FAQ)

Q: Can the ER2E_R1_00001 be used as a direct replacement for the ES2EB-HF in existing designs?

A: Yes. The ER2E_R1_00001 meets all primary electrical and mechanical specifications of the ES2EB-HF. Both components have identical voltage ratings (300V), current ratings (2A), forward voltage characteristics (1.25V @ 2A), recovery time (35ns), and package configuration (SMB/DO-214AA). Direct substitution is supported without circuit modification.

Q: What are the differences between these two parts?

A: The primary differences are manufacturer identity and secondary electrical characteristics. The ER2E_R1_00001 exhibits lower reverse leakage current (1µA versus 5µA at 300V) and lower junction capacitance (25pF versus 40pF at 4V, 1MHz). These represent performance improvements that do not restrict substitution compatibility.

Q: Are both parts available in the same package?

A: Yes. Both the ES2EB-HF and ER2E_R1_00001 are supplied in the SMB/DO-214AA surface mount package. Mechanical compatibility and PCB footprint requirements are identical.

Q: Do both parts have the same temperature operating range?

A: Yes. Both components operate across the junction temperature range of -55°C to 150°C, ensuring thermal compatibility in equivalent applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the ES2EB-HF and ER2E_R1_00001 are RoHS3 compliant, meeting environmental and regulatory requirements for restricted substance use.

Q: What is the basis for substitution between these parts?

A: Substitution is based on matching critical electrical parameters: reverse voltage rating, average rectified current, forward voltage drop, reverse recovery time, and package configuration. Both parts meet these criteria and are classified as parametric equivalents.
