Key Parameters

Substitute Part Grouping Explanation

Substitution for the TAP474J035SCS is determined by strict equivalence in the following parameters:

• Capacitance value: 0.47 µF (exact match required)
• Voltage rating: 35 V (minimum requirement; higher ratings are acceptable)
• Mounting type: Through hole radial configuration
• Physical dimensions: 0.177" diameter, 0.276" maximum height, 0.098" lead spacing
• Type: Conformal coated tantalum capacitor
• Operating temperature range: -55°C to 125°C minimum
• ESR: 13 Ohm (electrical performance equivalence)

The primary substitute identified is TAP474K035SCS, which maintains all critical electrical and mechanical parameters while differing only in tolerance specification (±10% versus ±5%). This tolerance difference does not affect physical compatibility or core electrical performance in general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

Both TAP474J035SCS and TAP474K035SCS are active production components manufactured by KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on tolerance requirements specific to the application circuit. The TAP474J035SCS with ±5% tolerance is suitable for applications requiring tighter capacitance accuracy. The TAP474K035SCS with ±10% tolerance is suitable for general-purpose applications where wider tolerance bands are acceptable. Both parts share identical physical dimensions, electrical performance characteristics, and environmental ratings, ensuring direct interchangeability in through-hole PCB designs.

Frequently Asked Questions (FAQ)

Q: Can TAP474K035SCS replace TAP474J035SCS in my circuit?

A: Yes, provided your circuit design tolerates ±10% capacitance variation. Both parts have identical voltage ratings, ESR, operating temperature ranges, and physical dimensions. The only difference is the capacitance tolerance specification.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have 0.177" diameter, 0.276" maximum seated height, and 0.098" lead spacing. They are mechanically interchangeable in radial through-hole PCB layouts.

Q: What is the significance of the conformal coating?

A: Conformal coating provides environmental protection for the tantalum capacitor element. Both substitute parts maintain this coating specification, ensuring equivalent protection in moisture-sensitive or harsh operating environments.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TAP474J035SCS and TAP474K035SCS are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the ESR specification and why is it important?

A: ESR (Equivalent Series Resistance) is 13 Ohm for both parts. This parameter affects ripple current handling and frequency response characteristics. Identical ESR values ensure equivalent electrical performance in filtering and energy storage applications.

Q: Can I use a higher voltage-rated substitute?

A: Substitution is based on the parameters provided. Both identified parts are rated for 35 V. Use only parts meeting the specified voltage rating and other electrical parameters for your application.
