SS2FL3-M3/I Equivalent & Substitute Parts

Part Overview

The SS2FL3-M3/I is a Schottky rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, classified within the eSMP® series. This surface mount component operates at 30 V DC reverse voltage with a 2 A average rectified current rating and is housed in a DO-219AB package. The part maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across all critical parameters. Alternative part numbers within the same base product family (SS2FL3) provide options for procurement flexibility, inventory availability, and application-specific requirements such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SS2FL3-M3/I is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 540 mV @ 2 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 200 µA @ 30 V
• Capacitance @ Vr, F: 145 pF @ 4V, 1MHz

Mechanical Parameters (Must Match Exactly):

• Package / Case: DO-219AB (SMF)
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C

Compliance Parameters (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• Product Status: Active

All identified substitute parts maintain identical electrical and mechanical specifications. Variations in packaging designation (tape & reel format) and automotive qualification (AEC-Q101) represent secondary differentiators that do not affect core substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

SS2FL3-M3/I (Primary Part)

This part number is suitable for general-purpose applications requiring a 30 V, 2 A Schottky rectifier diode in DO-219AB surface mount packaging. Active product status confirms ongoing manufacturer support and availability. RoHS3 compliance and MSL 1 rating support deployment in standard industrial and consumer electronics environments.

SS2FL3-M3/H (Direct Parametric Equivalent)

This substitute maintains identical electrical and mechanical specifications to the SS2FL3-M3/I. Selection of this part number is appropriate when procurement inventory or lead time considerations require an alternative source within the same product family. Active product status and equivalent compliance certifications ensure functional interchangeability.

SS2FL3HM3/H (Automotive-Qualified Equivalent)

This part number provides the same electrical and mechanical performance as the primary part with the addition of AEC-Q101 automotive qualification. Selection of this variant is required for applications subject to automotive industry standards or quality requirements. Active product status and equivalent compliance certifications apply.

Frequently Asked Questions (FAQ)

Q: Can SS2FL3-M3/H be used as a direct replacement for SS2FL3-M3/I?

A: Yes. Both parts share identical electrical parameters (30 V reverse voltage, 2 A average rectified current, 540 mV forward voltage at 2 A), identical mechanical specifications (DO-219AB package, surface mount), and equivalent compliance status (ROHS3, MSL 1). The parts are functionally interchangeable.

Q: What is the difference between SS2FL3-M3/H and SS2FL3HM3/H?

A: The electrical and mechanical specifications are identical. SS2FL3HM3/H carries AEC-Q101 automotive qualification, which is not present in SS2FL3-M3/H. Selection of SS2FL3HM3/H is required for automotive applications; otherwise, both parts are equivalent.

Q: Are all three parts housed in the same package?

A: Yes. All three parts use the DO-219AB (SMF) surface mount package. PCB footprint and reflow soldering parameters are identical across all variants.

Q: Do these parts have different operating temperature ranges?

A: No. All three parts operate across the same junction temperature range of -55°C to 150°C.

Q: What does the packaging designation "Tape & Reel (TR)" indicate?

A: Tape & Reel is a standard surface mount component packaging format for automated assembly. All three parts are supplied in this format, which is compatible with standard pick-and-place equipment.

Q: Are there any compliance or regulatory differences between the three parts?

A: All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level). SS2FL3HM3/H additionally carries AEC-Q101 automotive qualification. This qualification is not present in the other two variants.

Q: Can SS2FL3-M3/I be used in an automotive application?

A: SS2FL3-M3/I does not carry AEC-Q101 automotive qualification. For automotive applications, SS2FL3HM3/H is the appropriate selection.

Q: What is the significance of the "eSMP®" series designation?

A: eSMP® is the Vishay product series classification for these Schottky rectifier diodes. All three parts belong to this series.
