Substitute Part Grouping Explanation

Substitute parts for the M1FL-TP are selected strictly according to parameters critical for proper form, fit, and electrical performance. Allowed substitute parts must have:

The identical package and mounting footprint (DO-221AC (SMA-FL), Surface Mount)
Equal or greater maximum DC reverse voltage
Equal average rectified current (1A)
The same or lower forward voltage at the specified test current (1.1 V @ 1A)
Matching reverse leakage current specifications at tested voltage
Equivalent recovery speed specification within the class “Fast Recovery ≤ 500ns, > 200mA (Io)”
Matching operating temperature range

Only parts meeting every one of these conditions can be considered substitutes in this context.

Engineering Selection Recommendations

The M1FL-TP is classified as Obsolete. The M7FL-TP is Active and holds the same ROHS and REACH status. Selection of M7FL-TP as a substitute is supported by equal or improved electrical performance, equivalent mechanical characteristics, consistent compliance status, and continued device availability.

Frequently Asked Questions (FAQ)

Q1: What are the key conditions for substituting M1FL-TP with another part?
A1: The substitute must match the package (DO-221AC (SMA-FL)), mounting type (Surface Mount), average rectified current (1A), equal or higher maximum reverse voltage, forward voltage at 1A (1.1 V), reverse leakage current specification, recovery speed classification, and operating temperature range.

Q2: Is there any difference in the mechanical fit between M1FL-TP and M7FL-TP?
A2: No. Both utilize the same DO-221AC (SMA-FL) package and have the same surface mount form factor.

Q3: Why is a substitute required for M1FL-TP?
A3: The M1FL-TP has Product Status: Obsolete, necessitating an alternative for ongoing production or maintenance needs.

Q4: Is the M7FL-TP compatible with all applications designed for M1FL-TP?
A4: The M7FL-TP meets all specified electrical and mechanical parameters of the M1FL-TP, ensuring compatibility based on the provided criteria.

Q5: Are there compliance or certification differences between M1FL-TP and M7FL-TP?
A5: Both M1FL-TP and M7FL-TP are REACH Unaffected. No additional compliance differences are specified.
