Key Parameters

Substitute Part Grouping Explanation

Substitution within diode modules and rectifiers is determined by the following key parameters:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io) (per Diode): Must meet or exceed application requirements
• Mounting Type: Chassis Mount
• Package / Case: TO-249AB

Only parts matching these strict criteria are considered suitable substitutes for FST16040L within the same manufacturer and product series.

Parameter Comparison

Engineering Selection Recommendations

When selecting an equivalent or substitute part for the FST16040L diode module, key considerations are the product status and compliance data. FST16040L is marked as obsolete, requiring substitution with a currently active part such as FST10040. Both meet the same moisture sensitivity level and mounting specifications, and FST10040 is RoHS Compliant and listed as "Active," which is suitable for ongoing use where compliance and long-term availability are required.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters for substituting FST16040L in a design?
A1: Critical substitution criteria include diode configuration (1 Pair Common Cathode), Schottky technology, maximum DC reverse voltage (40 V), average rectified current, chassis mount type, and TO-249AB package.

Q2: How does FST10040 compare to FST16040L for electrical performance?
A2: FST10040 matches or exceeds the VR (40 V) and Io (100A vs 80A) of FST16040L. The forward voltage is 650 mV @ 100A compared to 600 mV @ 80A for FST16040L.

Q3: Do both parts have identical mechanical footprints?
A3: Both devices use the TO-249AB chassis mount package and supplier device package.

Q4: Is the operating temperature range equivalent across both parts?
A4: Yes, both FST16040L and FST10040 specify a junction operating temperature range of -55°C ~ 150°C.

Q5: Is inventory availability a concern for FST16040L?
A5: FST16040L is currently obsolete. FST10040 is active and available in stock, per provided inventory data.

Q6: Are there compliance or certification concerns with substituting FST16040L for FST10040?
A6: Both parts have Moisture Sensitivity Level 1 (Unlimited). FST10040 is RoHS Compliant. Compliance status should be verified per project acceptance criteria.
