Substitute Part Grouping Explanation

Substitute parts for the SS2FL4-M3/I are identified based on strict electrical and mechanical parameter equivalence. All substitute candidates share identical specifications across the following critical parameters:

  • Voltage - DC Reverse (Vr) (Max): 40 V
  • Current - Average Rectified (Io): 2 A
  • Voltage - Forward (Vf) (Max) @ If: 580 mV @ 2 A
  • Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
  • Current - Reverse Leakage @ Vr: 220 µA @ 40 V
  • Capacitance @ Vr, F: 125 pF @ 4V, 1MHz
  • Package / Case: DO-219AB (SMF)
  • Operating Temperature - Junction: -55°C ~ 150°C
  • Technology: Schottky
  • RoHS Status: ROHS3 Compliant
  • Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitutes differ only in packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) and, in one case, automotive qualification status. These differences do not affect electrical performance or functional compatibility in circuit applications.

Engineering Selection Recommendations

All three parts—SS2FL4-M3/I, SS2FL4-M3/H, and SS2FL4HM3/H—are Active products manufactured by Vishay General Semiconductor - Diodes Division and maintain full RoHS3 compliance and REACH unaffected status. Electrical performance is identical across all three variants.

SS2FL4-M3/I is supplied in Tape & Reel (TR) packaging format with 775 pieces in current inventory.

SS2FL4-M3/H is supplied in Cut Tape (CT) & Digi-Reel® packaging format with 23,423 pieces in current inventory. This variant is suitable for applications requiring smaller quantity handling or alternative reel formats.

SS2FL4HM3/H is supplied in Tape & Reel (TR) packaging format with 23,581 pieces in current inventory and carries AEC-Q101 automotive qualification. This variant is specified for automotive-grade applications requiring formal qualification documentation.

Selection between these parts depends on packaging requirements and application grade specifications. All three are electrically and mechanically interchangeable within their respective packaging and qualification contexts.

Frequently Asked Questions (FAQ)

Q: Can SS2FL4-M3/H be used as a direct replacement for SS2FL4-M3/I?

A: Yes. Both parts are electrically identical with matching voltage, current, and thermal specifications. The difference is packaging format: SS2FL4-M3/I uses Tape & Reel (TR) while SS2FL4-M3/H uses Cut Tape (CT) & Digi-Reel®. Component selection depends on assembly equipment compatibility and quantity requirements.

Q: What is the difference between SS2FL4-M3/H and SS2FL4HM3/H?

A: Both parts share identical electrical specifications and DO-219AB package geometry. SS2FL4HM3/H carries AEC-Q101 automotive qualification, making it suitable for automotive applications requiring formal qualification status. SS2FL4-M3/H is the standard industrial variant. Packaging format for both is Tape & Reel (TR).

Q: Are all three parts RoHS3 compliant?

A: Yes. SS2FL4-M3/I, SS2FL4-M3/H, and SS2FL4HM3/H are all RoHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: Can SS2FL4HM3/H be used in non-automotive applications?

A: Yes. SS2FL4HM3/H meets or exceeds all electrical and mechanical specifications required for standard industrial applications. The AEC-Q101 qualification is an additional certification that does not restrict use in non-automotive circuits.

Q: What is the operating temperature range for all three parts?

A: The junction operating temperature range is -55°C to 150°C for SS2FL4-M3/I, SS2FL4-M3/H, and SS2FL4HM3/H.

Q: Are there any differences in forward voltage drop between these parts?

A: No. All three parts specify identical forward voltage of 580 mV maximum at 2 A forward current.

Q: Which part should be selected for high-volume production?

A: SS2FL4-M3/H and SS2FL4HM3/H both have significantly higher inventory availability (23,423 and 23,581 pieces respectively) compared to SS2FL4-M3/I (775 pieces). Selection between these two depends on whether automotive qualification is required for the application.
