Key Parameters

Substitute Part Grouping Explanation

Substitute parts for FMM-22S are determined strictly by matching key electrical and mechanical specifications, including diode configuration, maximum reverse voltage (Vr), average rectified current (Io), forward voltage (Vf) at test current, switching speed, reverse leakage current at rated voltage, operating temperature range, mounting type, and package/case. Only parts with a 1 pair common cathode configuration, 200 V rating, and through-hole TO-220 package variants have been included.

Parameter Comparison

Engineering Selection Recommendations

Selection should prioritize substitute diodes with an active product status and matching RoHS/compliance certification. All listed alternatives possess RoHS compliance and MSL 1 status. Package/case compatibility should be verified with respect to board layout constraints, as alternative devices may utilize TO-220-3 or TO-220-3 Full Pack packages versus the original TO-220-2 Full Pack.

Frequently Asked Questions (FAQ)

Q: What criteria must be matched to substitute FMM-22S with another part?
A: Substitution is based strictly on diode configuration, maximum DC reverse voltage, average rectified current, forward voltage at the specified current, recovery speed, reverse leakage current, operating temperature range, mounting type, and package/case.

Q: Are package differences significant when substituting diodes?
A: Yes, the original FMM-22S uses a TO-220-2 Full Pack package. Substitute parts may use TO-220-3 or TO-220-3 Full Pack packages. Mechanical fit and pinout must align with PCB layout.

Q: Are all listed substitute parts RoHS compliant?
A: Yes, all substitute parts are RoHS or ROHS3 compliant and have a Moisture Sensitivity Level (MSL) of 1 (Unlimited).

Q: Does the speed or recovery time affect substitution?
A: Substitute selection in this reference is strictly aligned with the specified standard or fast recovery speed based on the main part’s classification.

Q: Can parts with a lower average rectified current (Io) be substituted?
A: Substitution is strictly based on the listed average rectified current for each part; RF1001T2D offers 5A per diode, versus FMM-22S’s 10A per diode. Only parameters explicitly given in the comparison should guide selection.
