Substitute Part Grouping Explanation

Substitution of the TAP685M016SCS is determined by strict equivalence across the following critical parameters:

• Capacitance Value: Must remain 6.8 µF
• Voltage Rating: Must be 16 V or higher
• Type: Must be conformal coated tantalum capacitor
• Mounting Configuration: Must be through-hole radial
• Physical Dimensions: Must match 0.197" diameter (5.00 mm) and 0.335" maximum seated height (8.50 mm)
• ESR: Must be 4 Ohm
• Operating Temperature Range: Must support -55°C to 125°C
• Lifetime Specification: Must meet 1000 Hrs @ 85°C

The TAP685K016SCS qualifies as a direct substitute because it maintains identical values across all critical parameters with the exception of tolerance, which is tightened from ±20% to ±10%. This represents an upgrade in tolerance specification while preserving all electrical and mechanical compatibility requirements.
