M2FL-TP Equivalent & Substitute Parts

Part Overview

The M2FL-TP is a fast recovery rectifier diode manufactured by Micro Commercial Co, rated for 100 V DC reverse voltage and 1 A average rectified current in a surface mount DO-221AC (SMA-FL) package. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design requirements and procurement continuity. The part operates across a junction temperature range of -55°C to 150°C and features fast recovery characteristics suitable for switching applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the M2FL-TP is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Mounting Type: Surface Mount (identical)
• Package / Case: DO-221AC, SMA Flat Leads (identical)
• Current - Average Rectified (Io): 1 A (identical)
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A (identical)
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io) (identical)
• Operating Temperature - Junction: -55°C to 150°C (identical)

Allowable Parameter Variance:

• Voltage - DC Reverse (Vr) (Max): The substitute part may exceed the original specification, provided the application circuit does not require the lower voltage rating as a design constraint.
• Current - Reverse Leakage @ Vr: Measured at the substitute part's rated voltage; lower leakage is acceptable.

The M7FL-TP qualifies as a direct substitute based on these criteria, with the primary distinction being an elevated reverse voltage rating of 1000 V compared to the original 100 V specification.

Parameter Comparison

Engineering Selection Recommendations

The M7FL-TP is an active substitute for the obsolete M2FL-TP. Both components share identical electrical performance characteristics for forward voltage drop, average rectified current, switching speed, and operating temperature range. The M7FL-TP maintains full compliance with REACH regulations and export classification (EAR99) equivalent to the original part.

The primary distinction is the reverse voltage rating: the M7FL-TP is rated for 1000 V compared to the M2FL-TP's 100 V specification. This higher rating does not degrade performance in applications designed for 100 V operation; the substitute part operates within the original design envelope while providing additional voltage margin.

Selection of the M7FL-TP is appropriate for direct replacement in existing designs without circuit modification. The identical package footprint (DO-221AC, SMA-FL), mounting type (surface mount), and thermal characteristics ensure mechanical and thermal compatibility.

Frequently Asked Questions (FAQ)

Q: Can the M7FL-TP directly replace the M2FL-TP in existing PCB designs?

A: Yes. Both parts use the DO-221AC (SMA-FL) surface mount package with identical footprints and pinouts. No PCB layout changes are required.

Q: What is the significance of the higher 1000 V rating on the M7FL-TP?

A: The M7FL-TP's 1000 V reverse voltage rating exceeds the original 100 V specification. In applications operating at or below 100 V, the higher rating provides additional safety margin without affecting circuit performance. The forward voltage drop, current capacity, and switching speed remain identical.

Q: Are there any thermal or reliability differences between these parts?

A: No. Both parts operate across the identical junction temperature range (-55°C to 150°C) and share the same fast recovery speed classification. Thermal performance and reliability characteristics are equivalent.

Q: Why is the M2FL-TP listed as obsolete?

A: The M2FL-TP is classified as obsolete by the manufacturer. The M7FL-TP is the active equivalent part available for procurement and new designs.

Q: Are compliance certifications identical between the two parts?

A: Yes. Both parts carry identical REACH status (REACH Unaffected) and export classification (EAR99).

Q: What is the reverse leakage current specification for the M7FL-TP?

A: The M7FL-TP specifies 5 µA reverse leakage current measured at its rated voltage of 1000 V, equivalent to the M2FL-TP's 5 µA specification measured at 100 V.
