TAP225K025FCS Equivalent & Substitute Parts

Part Overview

The TAP225K025FCS is a 2.2 µF conformal coated tantalum capacitor rated for 25 V operation in radial through-hole configuration. Manufactured by KYOCERA AVX, this component is classified as Active product status and is suitable for general-purpose applications requiring stable capacitance performance across industrial temperature ranges. Substitute parts may be required due to inventory constraints, supply chain availability, or specific packaging preferences while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the TAP225K025FCS is determined by strict equivalence across the following critical parameters:

Capacitance value: 2.2 µF (exact match required)
Tolerance: ±10% (exact match required)
Voltage rating: 25 V (exact match required)
Type: Conformal Coated (exact match required)
ESR: 6 Ohm (exact match required)
Operating temperature range: -55°C to 125°C (exact match required)
Lifetime specification: 1000 Hrs @ 85°C (exact match required)
Mounting type: Through Hole (exact match required)
Package: Radial (exact match required)
Size: 0.177" Dia (4.50 mm) (exact match required)
Height: 0.335" (8.50 mm) (exact match required)
Regulatory compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The identified substitute parts TAP225K025CCS and TAP225K025GSB meet all electrical and mechanical parameters. TAP225K025GSB is designated as the manufacturer-recommended substitute. A mechanical variation exists in lead spacing for TAP225K025GSB (0.125" vs. 0.197"), which must be evaluated for PCB layout compatibility.

Engineering Selection Recommendations

All three parts—TAP225K025FCS, TAP225K025CCS, and TAP225K025GSB—are Active product status from KYOCERA AVX and maintain full ROHS3 compliance and REACH Unaffected status. Selection between these parts should be based on:

PCB layout requirements: TAP225K025GSB features reduced lead spacing (0.125" vs. 0.197"), which may be advantageous for compact designs or incompatible with existing PCB footprints designed for the original 0.197" spacing.
Inventory availability: TAP225K025GSB offers the highest stock level (2934 Pcs), followed by TAP225K025CCS (1825 Pcs) and TAP225K025FCS (961 Pcs).
Direct electrical equivalence: All three parts deliver identical electrical performance across capacitance, voltage rating, ESR, temperature range, and lifetime specifications.

Frequently Asked Questions (FAQ)

Q: Can TAP225K025GSB be used as a direct replacement for TAP225K025FCS?

A: TAP225K025GSB is electrically equivalent to TAP225K025FCS across all specified parameters. However, the lead spacing differs (0.125" vs. 0.197"). Direct PCB substitution is possible only if the PCB footprint accommodates the reduced lead spacing, or if manual lead bending is acceptable for through-hole assembly.

Q: What is the difference between TAP225K025CCS and TAP225K025GSB?

A: TAP225K025CCS and TAP225K025GSB are electrically identical. The only difference is lead spacing: TAP225K025CCS maintains the standard 0.197" spacing, while TAP225K025GSB uses 0.125" spacing. Selection depends on PCB layout compatibility.

Q: Are all three parts suitable for the same circuit applications?

A: Yes. All three parts meet identical electrical specifications for capacitance, voltage rating, ESR, operating temperature range, and lifetime. Application suitability is determined by PCB layout constraints related to lead spacing.

Q: Do these parts require any special handling or storage conditions?

A: All parts are conformal coated tantalum capacitors with identical moisture sensitivity and storage requirements as specified by KYOCERA AVX. Refer to manufacturer datasheets for detailed handling and storage protocols.

Q: Are there any compliance or regulatory differences between these parts?

A: No. All three parts are ROHS3 Compliant and REACH Unaffected, with identical ECCN (EAR99) and HTSUS (8532.21.0040) classifications.
