Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FMC-26U diode array are determined by matching key electrical and mechanical parameters, specifically: Diode Configuration, Voltage - DC Reverse (Vr) (Max), Current - Average Rectified (Io) (per Diode), Speed classification, Reverse Recovery Time (trr), Operating Temperature - Junction, Package / Case, Mounting Type, RoHS status, and Moisture Sensitivity Level. All alternatives are included only when these parameters are within the same category allowances or superior per explicit data provided.

Parameter Comparison

Engineering Selection Recommendations

Selection between FMC-26U and its substitute STTH806TTI is based primarily on the product status and compliance certifications. FMC-26U is classified as "Obsolete" while STTH806TTI is "Active". Both parts meet the RoHS compliance and exhibit Moisture Sensitivity Level 1 (Unlimited). Both parts align with ECCN EAR99, which is suitable for general international shipments.

Frequently Asked Questions (FAQ)

Q1: What are the core substitution criteria for FMC-26U in the "Diodes, Rectifiers" category?
A1: Core criteria include matching Diode Configuration, Voltage - DC Reverse (Vr) (Max), Current - Average Rectified (Io), Speed, Reverse Recovery Time (trr), Mounting Type, Package / Case, RoHS compliance, and Moisture Sensitivity Level.

Q2: Is package compatibility ensured between FMC-26U and STTH806TTI?
A2: The main part uses TO-220-3 Full Pack and the substitute uses TO-220-3/TO-220AB Insulated. Both are through-hole packages; comparison should review dimensional data from manufacturers for mechanical fit.

Q3: Do both parts provide compliant and reliable RoHS and ECCN certifications?
A3: FMC-26U and STTH806TTI are both RoHS compliant and listed as ECCN EAR99.

Q4: What justifies substituting FMC-26U based strictly on product status?
A4: FMC-26U is "Obsolete"; active status substitutes such as STTH806TTI are necessary for continued product support.

Q5: Will moisture sensitivity or shipment compliance change with the substitute?
A5: Both devices are MSL 1 (Unlimited) and share the ECCN EAR99 code, keeping shipment and storage requirements equivalent.
