RL104-AP General Purpose Rectifier Diode Equivalent & Substitute Parts

Part Overview

The RL104-AP is a general purpose rectifier diode manufactured by Micro Commercial Co, rated for 400 V DC reverse voltage and 1 A average rectified current. This component is designed for through-hole mounting in axial package configuration and operates across a junction temperature range of -55°C to 150°C.

The RL104-AP is classified as obsolete. Identification of equivalent and substitute parts is necessary to support ongoing maintenance, repair, and production requirements for systems utilizing this component. Substitute parts must maintain electrical and mechanical compatibility within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RL104-AP is determined by the following critical electrical and mechanical parameters:

Voltage Rating: The substitute part must maintain a DC reverse voltage rating of 400 V or greater to ensure safe operation in the same circuit application.

Current Rating: The substitute part must support the required average rectified current. The RL104-AP is rated for 1 A; substitute parts with lower current ratings (such as 250 mA) are not suitable for direct replacement in applications requiring full 1 A operation.

Package and Mounting: The substitute part must use through-hole mounting with axial package configuration to ensure mechanical compatibility with existing printed circuit board layouts and assembly processes.

Temperature Range: The substitute part must support the operating junction temperature range of -55°C to 150°C or a range that encompasses the application's thermal requirements.

Compliance: The substitute part must meet RoHS compliance requirements applicable to the end application.

The EU01V1 is listed as a substitute for the RL104-AP based on matching voltage rating (400 V) and axial through-hole package configuration. However, the EU01V1 is rated for 250 mA average rectified current, which is below the 1 A rating of the RL104-AP.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The RL104-AP is classified as obsolete. The EU01V1 is an active product with current manufacturing and supply availability, making it suitable for applications where component sourcing is a primary concern.

Compliance: Both the RL104-AP and EU01V1 meet RoHS compliance requirements. The RL104-AP carries ROHS3 Compliant status, while the EU01V1 carries RoHS Compliant status. Both are acceptable for applications with RoHS requirements.

Current Rating Limitation: The EU01V1 is rated for 250 mA average rectified current, compared to the RL104-AP's 1 A rating. Selection of the EU01V1 is limited to applications where the actual circuit current demand does not exceed 250 mA. Applications requiring the full 1 A capacity of the RL104-AP cannot use the EU01V1 as a direct replacement.

Voltage and Package Compatibility: Both parts share identical 400 V DC reverse voltage rating and axial through-hole package configuration, ensuring electrical and mechanical compatibility within the voltage and package constraints.

Temperature Range: The EU01V1 operates from -40°C to 150°C, which is narrower than the RL104-AP range of -55°C to 150°C. Applications requiring operation below -40°C junction temperature cannot use the EU01V1.

Frequently Asked Questions (FAQ)

Q: Can the EU01V1 be used as a direct replacement for the RL104-AP in all applications?

A: No. The EU01V1 is rated for 250 mA average rectified current, while the RL104-AP is rated for 1 A. The EU01V1 can only be used in applications where the actual circuit current does not exceed 250 mA. Applications requiring 1 A operation require a substitute part with a 1 A or higher current rating.

Q: Are the package configurations compatible between the RL104-AP and EU01V1?

A: Yes. Both parts use axial through-hole package configuration, ensuring mechanical compatibility with printed circuit board layouts designed for the RL104-AP.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. The RL104-AP is ROHS3 Compliant, and the EU01V1 is RoHS Compliant. Both parts satisfy RoHS compliance requirements for their respective regulatory frameworks.

Q: What is the difference in forward voltage between the RL104-AP and EU01V1?

A: The RL104-AP has a maximum forward voltage of 1.1 V at 1 A, while the EU01V1 has a maximum forward voltage of 2.5 V at 250 mA. Forward voltage specifications are measured at different current levels and cannot be directly compared. The EU01V1's forward voltage characteristic applies only at its rated 250 mA current.

Q: Can the EU01V1 be used in applications requiring operation below -40°C?

A: No. The EU01V1 has a minimum operating junction temperature of -40°C, while the RL104-AP operates down to -55°C. Applications requiring operation below -40°C require a substitute part with a lower minimum temperature rating.

Q: What is the difference in reverse leakage current between the two parts?

A: The RL104-AP has a reverse leakage current of 5 µA at 400 V, while the EU01V1 has a reverse leakage current of 10 µA at 400 V. The EU01V1 exhibits twice the reverse leakage current of the RL104-AP under the same voltage conditions.

Q: Are there differences in recovery speed between the RL104-AP and EU01V1?

A: Yes. The RL104-AP is classified as standard recovery with a speed greater than 500 ns for currents above 200 mA. The EU01V1 is classified as fast recovery with a speed of 400 ns reverse recovery time. The EU01V1 exhibits faster switching characteristics than the RL104-AP.
