Substitute Part Grouping Explanation

Substitution of the SD125SCU100A.T2 is determined by electrical and mechanical parameter equivalence. The critical parameters that define interchangeability are:

Voltage Rating: 100V DC reverse voltage maximum
Current Rating: 15A average rectified current
Forward Voltage Drop: 840 mV maximum at 15A
Reverse Leakage Current: 350 µA at 100V
Package Type: Surface mount die configuration
Technology: Schottky rectifier diode
Temperature Range: -55°C to 200°C junction operating temperature
Compliance: RoHS3 and REACH compliance status

Parts meeting all these specifications are classified as parametric equivalents and direct substitutes. Packaging format (tray) and supplier device package (die) must remain consistent for manufacturing compatibility.

Frequently Asked Questions (FAQ)

Q: Are SD125SCU100A.T2 and SD125SCU100A.T electrically identical?

A: Yes. Both parts are Schottky rectifier diodes with identical electrical specifications: 100V reverse voltage rating, 15A average rectified current, 840 mV forward voltage drop at 15A, 350 µA reverse leakage current at 100V, and 600 pF capacitance at 5V and 1 MHz. Fast recovery speed characteristics are identical at ≤ 500ns for currents > 200mA.

Q: Can these parts be used interchangeably in circuit designs?

A: Yes. The SD125SCU100A.T and SD125SCU100A.T2 are direct substitutes with no circuit design modifications required. Both parts operate across the same temperature range (-55°C to 200°C junction temperature) and maintain identical performance characteristics in rectification, switching, and reverse recovery applications.

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

A: The part numbers differ only in the final suffix designation (.T2 versus .T). All electrical parameters, mechanical specifications, package configuration, and compliance certifications are identical. The suffix variation reflects internal SMC Diode Solutions manufacturing or distribution tracking but does not affect component performance or compatibility.

Q: Are both parts available in the same packaging format?

A: Yes. Both SD125SCU100A.T2 and SD125SCU100A.T are supplied in tray packaging as surface mount die components. The supplier device package specification is identical for both parts.

Q: Do these parts meet regulatory compliance requirements?

A: Yes. Both parts are ROHS3 compliant and REACH affected, meeting current environmental and hazardous substance regulations. Both carry MSL Level 1 (Unlimited) moisture sensitivity classification, requiring no special moisture control during storage or handling.

Q: Which part should be selected for new designs?

A: Selection is based on current inventory availability and supply chain requirements. Both parts are active products with identical specifications. The SD125SCU100A.T2 currently has higher inventory availability (1129 units) compared to SD125SCU100A.T (863 units).
