Key Parameters

Substitute Part Grouping Explanation

Substitution for the FK24X7R2E472KN006 is determined by the following critical parameters: capacitance value (4700 pF), lead spacing (5.00mm), mounting type (through-hole radial), and compliance certifications (ROHS3).

The substitute parts are grouped into two categories:

Direct Equivalent (Same Electrical Specifications): FG24X7R2E472KNT06 maintains identical capacitance, voltage rating, temperature coefficient, and tolerance. This part differs only in packaging format (Cut Tape vs. Tape & Box) and series designation, representing the active production equivalent.

Higher-Rated Alternatives (Enhanced Voltage Performance): FG26X7R2J472KNT06 and FG26C0G2J472JNT06 provide increased voltage ratings (630V) while maintaining the same 4700 pF capacitance and 5.00mm lead spacing. These parts accommodate applications requiring higher voltage margins or operating in elevated voltage environments. Physical dimensions increase slightly due to higher voltage requirements, but lead spacing remains compatible.

Engineering Selection Recommendations

For Direct Replacement: FG24X7R2E472KNT06 is the primary substitute, offering identical electrical performance with active product status and full ROHS3 compliance. This part is recommended for applications where the original 250V rating is sufficient and component availability is the primary concern.

For Enhanced Voltage Margin Applications: FG26X7R2J472KNT06 provides 630V rating with X7R temperature coefficient, suitable for circuits requiring higher voltage headroom while maintaining the same capacitance and tolerance specifications.

For Precision and Stability Requirements: FG26C0G2J472JNT06 offers C0G (NP0) temperature coefficient with tighter ±5% tolerance and 630V rating, appropriate for applications demanding superior temperature stability and capacitance accuracy.

All substitute parts maintain ROHS3 compliance and are currently in active production status, ensuring long-term availability and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can FG24X7R2E472KNT06 be used as a direct replacement for FK24X7R2E472KN006?

A: Yes. Both parts share identical capacitance (4700 pF), voltage rating (250V), temperature coefficient (X7R), tolerance (±10%), and lead spacing (5.00mm). The primary difference is packaging format and series designation. FG24X7R2E472KNT06 is the active production equivalent.

Q: What is the difference between X7R and C0G temperature coefficients?

A: X7R provides ±15% capacitance variation across the -55°C to 125°C operating range. C0G (NP0) provides superior stability with ±0.3% variation over the same range. C0G is preferred for precision timing and filtering circuits where capacitance stability is critical.

Q: Can I use the 630V-rated parts in a 250V circuit?

A: Yes. Higher voltage-rated capacitors are electrically compatible with lower voltage applications. FG26X7R2J472KNT06 and FG26C0G2J472JNT06 will function correctly in 250V circuits. Physical dimensions are slightly larger due to higher voltage requirements, but lead spacing remains at 5.00mm for PCB compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. FK24X7R2E472KN006, FG24X7R2E472KNT06, FG26X7R2J472KNT06, and FG26C0G2J472JNT06 are all ROHS3 compliant.

Q: What is the significance of "Not For New Designs" status?

A: This designation indicates the FK24X7R2E472KN006 has been superseded in TDK's product line. While suitable for maintenance and repair of existing systems, new circuit designs should specify active production parts such as FG24X7R2E472KNT06 or higher-rated alternatives to ensure long-term supply availability.

Q: How do physical dimensions affect PCB layout compatibility?

A: All substitute parts maintain the same 5.00mm lead spacing, ensuring PCB footprint compatibility. FK24X7R2E472KN006 and FG24X7R2E472KNT06 have identical body dimensions (0.177" L x 0.098-0.118" W). FG26X7R2J472KNT06 and FG26C0G2J472JNT06 have larger bodies (0.217" L x 0.138" W) due to higher voltage rating but retain the same lead spacing for through-hole mounting.
