TAP156M025FCS Equivalent & Substitute Parts

Part Overview

The TAP156M025FCS is a 15 µF conformal coated tantalum capacitor rated at 25 V with radial through-hole mounting. Manufactured by KYOCERA AVX, this component is classified as Active product status and is designed for general-purpose applications requiring reliable energy storage in compact form factors.

Substitute parts become necessary when inventory constraints occur, when tighter tolerance specifications are required for precision circuits, or when design revisions call for enhanced performance characteristics while maintaining mechanical and electrical compatibility.

Substitute Part Grouping Explanation

The TAP156K025CCS qualifies as a direct substitute for the TAP156M025FCS based on the following alignment of critical parameters:

• Capacitance Value: Both parts are rated at 15 µF
• Voltage Rating: Both parts are rated at 25 V
• ESR: Both parts have 2 Ohm equivalent series resistance
• Conformal Coating: Both parts feature conformal coating for environmental protection
• Mounting Configuration: Both parts use through-hole radial mounting
• Physical Dimensions: Both parts share identical package dimensions (0.236" Dia, 0.453" Height, 0.197" lead spacing)
• Operating Temperature: Both parts operate across -55°C to 125°C
• Compliance: Both parts are ROHS3 compliant and REACH unaffected

The primary distinction between these parts is the tolerance specification: TAP156M025FCS carries ±20% tolerance, while TAP156K025CCS carries ±10% tolerance. This represents an upgrade in precision capability.

Parameter Comparison

Engineering Selection Recommendations

Both TAP156M025FCS and TAP156K025CCS are Active product status components manufactured by KYOCERA AVX and maintain full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on tolerance requirements for the specific application circuit.

The TAP156M025FCS with ±20% tolerance is suitable for general-purpose applications where capacitance variation within this range does not impact circuit performance. The TAP156K025CCS with ±10% tolerance provides enhanced precision and is appropriate for circuits requiring tighter capacitance control or where the design margin accommodates only half the tolerance band of the standard part.

Both parts are electrically and mechanically interchangeable within their respective tolerance specifications, with identical ESR characteristics, thermal performance, and environmental protection through conformal coating.

Frequently Asked Questions (FAQ)

Q: Can TAP156K025CCS replace TAP156M025FCS in existing designs?

A: Yes. The TAP156K025CCS is a direct mechanical and electrical substitute. The primary difference is improved tolerance (±10% versus ±20%), which represents an upgrade in precision. No PCB layout modifications are required.

Q: What is the significance of the tolerance difference between these parts?

A: Tolerance defines the acceptable range of actual capacitance value around the nominal 15 µF specification. TAP156M025FCS allows ±20% variation (12–18 µF), while TAP156K025CCS allows ±10% variation (14.6–16.5 µF). Applications sensitive to capacitance accuracy should use the ±10% part.

Q: Are the physical dimensions identical?

A: Yes. Both parts share identical package dimensions: 0.236" diameter, 0.453" maximum seated height, and 0.197" lead spacing. They are footprint-compatible for through-hole PCB mounting.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and rated for -55°C to 125°C operation with 1000 hours lifetime at 85°C.

Q: What does ESR mean and why is it the same for both parts?

A: ESR (Equivalent Series Resistance) represents the internal resistance of the capacitor at operating frequency. Both parts have 2 Ohm ESR, indicating identical high-frequency performance characteristics and ripple current handling capability.
