Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following parameters:

• Capacitance: 22 µF (exact match required)
• Voltage Rating: 16 V (exact match required)
• Type: Conformal Coated Tantalum (exact match required)
• Mounting Type: Through Hole Radial (exact match required)
• Tolerance: ±20% or tighter (±10% acceptable as improvement)
• Operating Temperature: Minimum -55°C to +105°C coverage required

All listed substitutes meet these core criteria. Tolerance improvements (±10% vs. ±20%) and extended temperature ranges represent enhancements over the original specification. Physical dimensions vary within acceptable mechanical compatibility for radial through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts satisfy the core electrical and mechanical requirements for direct replacement of the ECS-F1CE226K. Selection should prioritize the following factors:

For RoHS3 Compliance Requirements: TAP226K016SCS (KYOCERA AVX), 199D226X0016D1V1E3 (Vishay Sprague), and T350F226K016AT (KEMET) are compliant. The ECS-F1CE226K and T350F226K016AS are non-compliant.

For Improved Tolerance: T350F226K016AS, TAP226K016SCS, and T350F226K016AT offer ±10% tolerance versus the original ±20%, reducing capacitance variation in circuit operation.

For Extended Temperature Range: All substitutes support -55°C to 125°C operation, exceeding the original -55°C to 105°C range.

For Availability: All substitute parts are listed as active products with current inventory, ensuring supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can T350F226K016AS replace ECS-F1CE226K directly? A: Yes. Both parts share identical capacitance (22 µF), voltage rating (16 V), type (conformal coated tantalum), and radial through-hole mounting. The T350F226K016AS offers improved ±10% tolerance and extended temperature range. However, it is RoHS non-compliant, matching the original part's compliance status.

Q: What is the difference between T350F226K016AS and T350F226K016AT? A: Both are KEMET T350 series parts with identical electrical specifications (22 µF, 16 V, ±10% tolerance, 2 Ohm ESR). The primary difference is RoHS compliance: T350F226K016AT is ROHS3 compliant, while T350F226K016AS is non-compliant. Physical dimensions are identical.

Q: Are there mechanical compatibility concerns with substitute parts? A: All substitutes use radial through-hole packaging compatible with the original ECS-F1CE226K footprint. Physical dimensions vary slightly (diameter 5.20 mm to 6.00 mm, height 8.50 mm to 10.00 mm, lead spacing 2.50 mm to 2.54 mm), but these variations remain within acceptable tolerances for standard PCB through-hole layouts. Verify PCB hole spacing and clearance for your specific application.

Q: Which substitute offers the best compliance profile? A: TAP226K016SCS (KYOCERA AVX), 199D226X0016D1V1E3 (Vishay Sprague), and T350F226K016AT (KEMET) are all ROHS3 compliant with REACH unaffected status. TAP226K016SCS additionally specifies 1000 Hrs @ 85°C lifetime rating.

Q: Can I use 199D226X0016D1V1E3 as a direct substitute? A: Yes. The 199D226X0016D1V1E3 maintains the original ±20% tolerance and adds ROHS3 compliance and extended temperature range. It is functionally equivalent with improved regulatory status.
