Substitute Part Grouping Explanation

Substitute parts for the SS3P4L-M3/87A are identified based on strict electrical and mechanical parameter matching. All substitute candidates must satisfy the following criteria:

Critical Matching Parameters:

Voltage - DC Reverse (Vr) (Max): 40 V
Current - Average Rectified (Io): 3 A
Voltage - Forward (Vf) (Max) @ If: 470 mV @ 3 A
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Current - Reverse Leakage @ Vr: 250 µA @ 40 V
Package / Case: TO-277, 3-PowerDFN
Mounting Type: Surface Mount
Operating Temperature - Junction: -55°C to 150°C
Technology: Schottky
RoHS Status: ROHS3 Compliant

All identified substitute parts meet these electrical and mechanical specifications. Variations in packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) and automotive qualification (AEC-Q101) represent secondary differentiators that do not affect functional equivalence in standard applications.

Engineering Selection Recommendations

All substitute parts listed—SS3P4L-M3/86A, SS3P4LHM3_A/H, and SS3P4LHM3_A/I—are functionally equivalent to the SS3P4L-M3/87A based on electrical and mechanical parameter alignment. Selection among these equivalents depends on application-specific requirements and supply chain considerations:

SS3P4L-M3/86A: Direct parametric equivalent with identical specifications and standard packaging format (Tape & Reel). Suitable for general industrial applications requiring standard-grade Schottky rectifiers.

SS3P4LHM3_A/H: Parametric equivalent with automotive-grade qualification (AEC-Q101) and Tape & Reel packaging. Appropriate for automotive and mission-critical applications where AEC-Q101 certification is required or preferred.

SS3P4LHM3_A/I: Parametric equivalent with automotive-grade qualification (AEC-Q101) and alternative packaging format (Cut Tape & Digi-Reel®). Suitable for automotive applications with specific packaging or reel format requirements.

All parts maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and active production status. Selection should be based on application grade requirements, packaging format compatibility with assembly processes, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can SS3P4L-M3/86A be used as a direct replacement for SS3P4L-M3/87A?

A: Yes. SS3P4L-M3/86A is a parametric equivalent with identical electrical specifications (40 V, 3 A, 470 mV forward voltage, fast recovery speed) and mechanical package (TO-277A SMPC). Both are standard-grade components with Tape & Reel packaging.

Q: What is the difference between standard-grade and automotive-grade versions?

A: SS3P4LHM3_A/H and SS3P4LHM3_A/I are automotive-grade components with AEC-Q101 qualification, indicating compliance with automotive industry reliability and testing standards. The SS3P4L-M3/87A and SS3P4L-M3/86A are standard-grade components without automotive qualification. Electrical and mechanical specifications remain identical across all versions.

Q: Are there packaging differences between the substitute parts?

A: SS3P4L-M3/87A, SS3P4L-M3/86A, and SS3P4LHM3_A/H are supplied in Tape & Reel (TR) format. SS3P4LHM3_A/I is available in Cut Tape (CT) & Digi-Reel® format. All use the same TO-277A (SMPC) package for surface mount assembly. Packaging format selection depends on assembly equipment compatibility and procurement preferences.

Q: Do all substitute parts have the same temperature operating range?

A: Yes. All substitute parts operate across the junction temperature range of -55°C to 150°C, ensuring thermal compatibility in equivalent applications.

Q: Is RoHS3 compliance consistent across all parts?

A: Yes. All listed parts—SS3P4L-M3/87A, SS3P4L-M3/86A, SS3P4LHM3_A/H, and SS3P4LHM3_A/I—are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Q: Which substitute part should be selected for automotive applications?

A: SS3P4LHM3_A/H or SS3P4LHM3_A/I should be selected for automotive applications due to AEC-Q101 qualification. Choice between these two depends on packaging format requirements: Tape & Reel for SS3P4LHM3_A/H or Cut Tape & Digi-Reel® for SS3P4LHM3_A/I.

Q: Are the forward voltage and reverse leakage specifications identical across all parts?

A: Yes. All substitute parts maintain 470 mV maximum forward voltage at 3 A and 250 µA maximum reverse leakage current at 40 V, ensuring identical electrical performance in circuit applications.
