Substitute Part Grouping Explanation

Substitution of the TAP475M025F is permissible when the following conditions are met:

Critical Parameters (Must Match Exactly):

• Capacitance: 4.7 µF
• Voltage Rating: 25 V
• Mounting Type: Through Hole Radial
• Package Dimensions: 0.197" Dia (5.00 mm), Height 0.394" (10.00 mm)
• Lead Spacing: 0.197" (5.00 mm)
• ESR: 4 Ohm
• Operating Temperature Range: -55°C to 125°C
• Type: Conformal Coated

Relaxable Parameters:

• Tolerance: May be tightened from ±20% to ±10% without affecting circuit compatibility

The TAP475K025CCS qualifies as a direct substitute because it maintains all critical electrical and mechanical parameters while offering improved tolerance specification (±10% versus ±20%).

Parameter Comparison

Engineering Selection Recommendations

Both the TAP475M025F and TAP475K025CCS are active production components with identical RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on tolerance requirements:

• TAP475M025F (±20% tolerance): Suitable for general-purpose applications where standard tolerance specifications are acceptable.
• TAP475K025CCS (±10% tolerance): Appropriate for applications requiring tighter capacitance tolerance control or where circuit performance benefits from improved tolerance margins.

Both parts are manufactured by KYOCERA AVX and share identical electrical characteristics, thermal performance, and mechanical form factors, ensuring direct interchangeability at the board level.

Frequently Asked Questions (FAQ)

Q: Can TAP475K025CCS replace TAP475M025F in existing designs?

A: Yes. The TAP475K025CCS is a direct substitute with identical capacitance, voltage rating, ESR, operating temperature range, and physical dimensions. The only difference is improved tolerance specification (±10% versus ±20%), which does not compromise compatibility.

Q: Are there any PCB layout considerations when switching between these parts?

A: No. Both parts share identical lead spacing (0.197" / 5.00 mm), package diameter (0.197" / 5.00 mm), and maximum seated height (0.394" / 10.00 mm). PCB footprints are directly interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TAP475M025F and TAP475K025CCS are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: What is the difference between ±20% and ±10% tolerance?

A: Tolerance specifies the allowable deviation from the nominal capacitance value. TAP475M025F allows ±20% deviation (3.76 µF to 5.64 µF), while TAP475K025CCS allows ±10% deviation (4.23 µF to 5.17 µF). Tighter tolerance provides more predictable capacitance values in production.

Q: Are both parts available in the same packaging format?

A: Yes. Both parts are supplied in bulk packaging as through-hole radial components with identical physical specifications.
