Engineering Selection Recommendations

The main part number 6CWQ06FN is obsolete and does not meet RoHS compliance. The substitute parts VS-6CWQ06FN-M3 and VS-6CWQ06FNHM3 match key electrical and mechanical parameters and offer ROHS3 compliance, with active product status. RB085BM-60TL also provides parametric compatibility, a higher current rating, and ROHS3 compliance. All substitutes are available in the same mounting type and package format.

Frequently Asked Questions (FAQ)

Q1: What parameters must match for safe substitution of a diode array in this category?
A1: The essential parameters for substitution include diode configuration, Schottky technology, maximum reverse voltage, average rectified current per diode, forward voltage at rated current, switching speed, reverse leakage current, operating temperature range, mounting type, and package/case.

Q2: Are ROHS3 compliant alternatives available for the 6CWQ06FN?
A2: Yes, VS-6CWQ06FN-M3, VS-6CWQ06FNHM3, and RB085BM-60TL offer ROHS3 compliance, while the original 6CWQ06FN is RoHS non-compliant.

Q3: Does package type affect substitutability for surface mount diodes, rectifiers?
A3: Compatibility requires identical package specifications. All listed substitutes use the TO-252-3, DPAK (2 Leads + Tab) format, ensuring interchangeability with standardized footprint and thermal characteristics.

Q4: What differences exist in current rating among alternatives?
A4: RB085BM-60TL supports a higher average rectified current rating (5A) compared to the original and the Vishay equivalents (3.5A).

Q5: Is AEC-Q101 qualification relevant for these substitutes?
A5: Only VS-6CWQ06FNHM3 provides automotive AEC-Q101 qualification as indicated in the supplied parameters.
