Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAP226M025CCS is determined by strict adherence to the following parameters:

Critical Parameters (Must Match Exactly):

• Capacitance: 22 µF
• Voltage Rating: 25 V
• Type: Conformal Coated Tantalum
• ESR: 1.5 Ohm
• Mounting Type: Through Hole Radial
• Package Dimensions: 0.276" Dia (7.00mm), Height 0.472" (12.00mm)
• Lead Spacing: 0.197" (5.00mm)
• Operating Temperature Range: -55°C to 125°C

Allowable Variation Parameter:

• Tolerance: ±20% (main part) to ±10% (substitute part) — tighter tolerance is acceptable as a direct upgrade

The TAP226K025CCS qualifies as a substitute because it maintains all critical electrical and mechanical parameters while offering improved capacitance tolerance (±10% versus ±20%), making it suitable for applications where tighter tolerance specifications are beneficial or required.

Parameter Comparison

Engineering Selection Recommendations

Both the TAP226M025CCS and TAP226K025CCS maintain active product status and full ROHS3 compliance. The TAP226K025CCS represents a direct upgrade path due to its tighter capacitance tolerance specification (±10% versus ±20%), while preserving all electrical performance characteristics including ESR, voltage rating, and thermal operating range. Selection between these parts should be based on application tolerance requirements and inventory availability. Both parts are suitable for conformal-coated applications requiring environmental protection in through-hole radial configurations.

Frequently Asked Questions (FAQ)

Q: Can TAP226K025CCS replace TAP226M025CCS in existing designs? A: Yes. The TAP226K025CCS is a direct substitute with identical electrical and mechanical specifications. The tighter tolerance (±10%) makes it suitable for all applications originally designed for the ±20% tolerance part.

Q: What is the primary difference between these two parts? A: The sole difference is capacitance tolerance. TAP226M025CCS specifies ±20% tolerance, while TAP226K025CCS specifies ±10% tolerance. All other parameters—capacitance value, voltage rating, ESR, package dimensions, and thermal characteristics—are identical.

Q: Are both parts suitable for conformal coating applications? A: Yes. Both parts are conformal coated tantalum capacitors designed for environmental protection in through-hole radial mounting configurations.

Q: Do these parts have identical PCB footprints? A: Yes. Both parts share identical lead spacing (0.197" / 5.00mm), package diameter (0.276" / 7.00mm), and seated height (0.472" / 12.00mm), ensuring direct board-level compatibility.

Q: What compliance certifications apply to both parts? A: Both TAP226M025CCS and TAP226K025CCS are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
