Manufacturer Recommended Alternative:

DST580S-A (Littelfuse): Active product status. This part differs in reverse voltage rating (80 V vs. 90 V), forward voltage (720 mV vs. 880 mV @ 5 A), reverse leakage current (400 µA vs. 15 µA @ rated voltage), and capacitance (245 pF vs. 130 pF). Package variant is TO-277B. Maintains automotive grade and AEC-Q101 qualification. Inventory: 762 pcs. This alternative is suitable only for applications where the reduced voltage rating and increased leakage current are acceptable.

Frequently Asked Questions (FAQ)

Q: Can SS5P9-M3/86A, SS5P9-M3/87A, SS5P9HM3_A/H, and SS5P9HM3_A/I be used interchangeably with the obsolete SS5P9HM3/86A?

A: Yes. These four parts are parametric equivalents with identical electrical specifications (90 V reverse voltage, 5 A current rating, 880 mV forward voltage @ 5 A, 15 µA reverse leakage @ 90 V, 130 pF capacitance). All maintain the same operating temperature range (-55°C to 150°C), surface mount configuration, and TO-277 package family. The primary differences are product status (all active), packaging formats (Cut Tape, Digi-Reel, or Tape & Reel), and inventory levels.

Q: What is the difference between TO-277A and TO-277B packages?

A: The SS5P9HM3/86A uses TO-277A (SMPC) package, while the DST580S-A alternative uses TO-277B package. These are distinct package variants within the TO-277 family. Physical compatibility must be verified against PCB footprint specifications before substitution.

Q: Is the DST580S-A (Littelfuse) a direct replacement for the SS5P9HM3/86A?

A: No. While DST580S-A shares the same 5 A current rating and operating temperature range, it has a lower reverse voltage rating (80 V vs. 90 V), lower forward voltage (720 mV vs. 880 mV @ 5 A), higher reverse leakage current (400 µA vs. 15 µA @ rated voltage), and higher capacitance (245 pF vs. 130 pF). This part is suitable only for applications where these parameter differences are acceptable and the 80 V reverse voltage rating is sufficient.

Q: Are all substitute parts automotive-qualified?

A: The parametric equivalents SS5P9HM3_A/H and SS5P9HM3_A/I carry automotive grade and AEC-Q101 qualification, matching the original part. SS5P9-M3/86A and SS5P9-M3/87A do not list automotive grade or AEC-Q101 qualification in their specifications. The DST580S-A alternative maintains automotive grade and AEC-Q101 qualification. Verify automotive qualification requirements for your specific application before selection.

Q: What is the inventory status of each substitute part?

A: SS5P9HM3_A/I has the highest inventory (39,300 pcs), followed by SS5P9-M3/87A (18,300 pcs), SS5P9-M3/86A (12,300 pcs), SS5P9HM3_A/H (1,800 pcs), and DST580S-A (762 pcs). Inventory levels should be confirmed with suppliers for current availability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (SS5P9-M3/86A, SS5P9-M3/87A, SS5P9HM3_A/H, SS5P9HM3_A/I, and DST580S-A) are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Q: What packaging options are available for the parametric equivalents?

A: SS5P9-M3/86A is available in Cut Tape (CT) and Digi-Reel® formats. SS5P9-M3/87A, SS5P9HM3_A/H, SS5P9HM3_A/I, and DST580S-A are available in Tape & Reel (TR) format. Packaging selection depends on production volume and assembly equipment compatibility.
