SR506-TP Equivalent & Substitute Parts

Part Overview

The SR506-TP is an active Schottky rectifier diode manufactured by Micro Commercial Co, rated for 60V DC reverse voltage and 5A average rectified current in a DO-201AD axial through-hole package. This component is designed for fast recovery applications requiring low forward voltage drop characteristics. Equivalent and substitute parts are identified based on matching electrical specifications, package compatibility, and compliance certifications to support circuit design flexibility and supply chain continuity.

Substitute Part Grouping Explanation

Substitution of the SR506-TP is determined by equivalence across the following critical parameters:

Electrical Equivalence Criteria:

Voltage - DC Reverse (Vr) (Max): 60V
Current - Average Rectified (Io): 5A
Voltage - Forward (Vf) (Max) @ If: 700 mV @ 5A
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Technology: Schottky

Mechanical Equivalence Criteria:

Package / Case: DO-201AD, Axial
Mounting Type: Through Hole

Compliance Equivalence Criteria:

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

The substitute part SB560A-E3/73 meets all electrical and mechanical equivalence criteria. Differences in reverse leakage current and capacitance specifications do not preclude substitution when these parameters are not critical to circuit function.

Engineering Selection Recommendations

Primary Selection (SR506-TP): The SR506-TP is the specified component and remains the first choice for new designs and existing production runs. It is active, ROHS3 compliant, and carries full manufacturer support.

Substitute Selection (SB560A-E3/73): The SB560A-E3/73 is a direct electrical and mechanical substitute for the SR506-TP. Both components are active products with ROHS3 compliance and REACH unaffected status. The substitute exhibits lower reverse leakage current (500 µA versus 1 mA at 60V), which may provide improved performance in applications sensitive to leakage. The substitute also supports a wider operating temperature range (-65°C to 150°C versus -50°C to 150°C), offering additional thermal margin in low-temperature environments.

Selection between these parts should be based on supply availability, lead time requirements, and cost considerations. Both components are suitable for identical circuit applications without design modification.

Frequently Asked Questions (FAQ)

Q: Can SB560A-E3/73 be used as a direct replacement for SR506-TP in existing circuits?

A: Yes. Both components share identical electrical ratings (60V, 5A, 700mV forward voltage, fast recovery characteristics) and the same DO-201AD axial through-hole package. No circuit modification is required for substitution.

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

A: The SR506-TP specifies 1 mA reverse leakage at 60V, while the SB560A-E3/73 specifies 500 µA at 60V. The substitute exhibits lower leakage. This difference is not significant for most rectifier applications but may be relevant in high-impedance or precision analog circuits.

Q: Are both parts RoHS compliant?

A: Yes. Both SR506-TP and SB560A-E3/73 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the operating temperature range for each part?

A: The SR506-TP operates from -50°C to 150°C junction temperature. The SB560A-E3/73 operates from -65°C to 150°C, providing a 15°C lower temperature limit. For applications requiring operation below -50°C, the substitute is the appropriate choice.

Q: Are the packages physically identical?

A: Yes. Both components use the DO-201AD axial through-hole package. They are mechanically interchangeable on printed circuit boards without modification to board layout or component footprints.

Q: What is the moisture sensitivity level for both parts?

A: Both components carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly.
