• Maximum DC reverse voltage (400 V)
• Average rectified current per diode (≥10A)
• Maximum forward voltage at the rated current
• Maximum reverse leakage current at rated reverse voltage
• Operating junction temperature range
• Mounting type (Through Hole)
• Package/case specifications within standard through-hole TO-220 form factors
• RoHS compliance
• Moisture Sensitivity Level (MSL)
• ECCN and HTSUS codes for regulatory alignment

Parameter Comparison

Engineering Selection Recommendations

FMM-24R is classified as Obsolete, and the substitute SDURF3040CTR is Active. Both components are RoHS compliant and have MSL 1 (Unlimited), supporting unrestricted moisture sensitivity handling. ECCN and HTSUS classifications are identical, indicating consistent regulatory status. Selection of SDURF3040CTR is supported by its active status and compliance with all provided environmental certifications.

Frequently Asked Questions (FAQ)

Q1: What parameters must match when substituting FMM-24R?
A: The substitute must meet or exceed the diode configuration, maximum DC reverse voltage, average rectified current per diode, forward voltage at rated current, reverse leakage current, operating junction temperature, mounting type, and package compatibility.

Q2: Is the SDURF3040CTR pin- and package-compatible with FMM-24R?
A: Both parts are through-hole and follow industry-standard TO-220 full pack formats; however, connector tab and lead configurations differ. Mechanical fit should be cross-checked against the application’s footprint and isolation requirements according to the provided package details.

Q3: Are there differences in compliance and regulatory status?
A: Both FMM-24R and SDURF3040CTR are RoHS compliant, have identical ECCN and HTSUS codes, and MSL 1 classification, ensuring compatibility from a compliance and handling perspective.

Q4: Can the substitute part support higher average rectified current?
A: SDURF3040CTR supports 15A average rectified current per diode, compared to FMM-24R’s 10A, which is within allowed substitution criteria per provided parameters.

Q5: Does the operating temperature range differ?
A: SDURF3040CTR supports a wider junction temperature range of -55°C ~ 150°C versus -40°C ~ 150°C for FMM-24R. Both ranges cover the specified -40°C ~ 150°C operational requirements.
