Substitute Part Grouping Explanation

Substitution of Schottky rectifier diodes is determined by electrical and mechanical parameter equivalence. The SS2P3LHM3/84A and its identified substitute operate under identical specifications across all critical performance parameters: reverse voltage rating, average rectified current, forward voltage drop, recovery speed, reverse leakage current, and junction capacitance. Both components utilize the DO-220AA surface mount package, ensuring mechanical and thermal compatibility. The substitution logic is based strictly on matching these electrical characteristics and package specifications, which define functional interchangeability in rectification applications.

Engineering Selection Recommendations

Both SS2P3LHM3/84A and SS2P3L-M3/84A are active production components from Vishay General Semiconductor - Diodes Division with identical electrical and mechanical specifications. Selection between these parts is based on inventory availability and supply chain requirements rather than functional differences. The SS2P3LHM3/84A carries automotive-grade qualification under AEC-Q101, making it suitable for applications requiring automotive compliance. The SS2P3L-M3/84A provides equivalent electrical performance and is appropriate for general industrial applications. Both components comply with ROHS3 and REACH regulations, ensuring environmental and regulatory compatibility. Component selection should be determined by application-specific compliance requirements and current inventory status.

Frequently Asked Questions (FAQ)

Q: Are SS2P3LHM3/84A and SS2P3L-M3/84A electrically interchangeable?

A: Yes. Both components share identical electrical specifications including 30 V reverse voltage rating, 2 A average rectified current, 500 mV forward voltage drop at 2 A, fast recovery speed characteristics, and reverse leakage current ratings. They operate across the same temperature range and exhibit identical junction capacitance.

Q: What is the difference between these two part numbers?

A: The primary difference is automotive qualification. SS2P3LHM3/84A carries AEC-Q101 automotive-grade certification, while SS2P3L-M3/84A does not include this designation. Both parts are manufactured by Vishay and use the DO-220AA surface mount package.

Q: Can these diodes be used interchangeably in PCB designs?

A: Yes. Both components use the DO-220AA (SMP) package with identical mechanical dimensions and pin configuration. PCB layouts designed for one part number accommodate the other without modification.

Q: What applications require the automotive-qualified version?

A: The SS2P3LHM3/84A with AEC-Q101 qualification is specified for automotive applications where component traceability, reliability testing, and compliance documentation are mandatory. Non-automotive applications may use either variant based on availability.

Q: Are there any environmental or regulatory differences?

A: No. Both components are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity level is 1 (Unlimited) for both parts, indicating no special handling requirements during storage or assembly.

Q: What is the significance of the DO-220AA package designation?

A: DO-220AA is a surface mount package specification that defines the physical dimensions, lead configuration, and thermal characteristics. Both substitute parts use this identical package, ensuring compatibility with existing PCB designs and assembly processes.
