Substitute Part Grouping Explanation

Substitution eligibility for the ECQ-E4473KFZ is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.047 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 400V (minimum requirement; higher ratings acceptable)
• Dielectric Material: Polyester, Metallized (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Physical dimensions and lead spacing (exact match required for PCB compatibility)
• Termination type: PC Pins (exact match required)

The ECQ-E4473KF meets all substitution criteria as a parametric equivalent within the ECQ-E(F) series.

Parameter Comparison

Engineering Selection Recommendations

Both the ECQ-E4473KFZ and ECQ-E4473KF are Active status components manufactured by Panasonic Electronic Components within the ECQ-E(F) series. Both parts maintain ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component procurement. The ECQ-E4473KF provides equivalent electrical performance and mechanical compatibility for direct substitution in applications requiring 0.047 µF, 400V DC rated film capacitors with polyester metallized dielectric construction.

Frequently Asked Questions (FAQ)

Q: Can ECQ-E4473KF replace ECQ-E4473KFZ in my circuit?

A: Yes. The ECQ-E4473KF is a parametric equivalent with identical capacitance (0.047 µF), tolerance (±10%), DC voltage rating (400V), dielectric material (polyester metallized), operating temperature range (-40°C ~ 105°C), and physical dimensions. Both components feature radial through-hole mounting with identical lead spacing (10.00mm) and PC pin termination, ensuring direct PCB compatibility.

Q: What is the difference between these two part numbers?

A: The ECQ-E4473KF includes an AC voltage rating specification (200V AC) not listed for the ECQ-E4473KFZ. All other electrical and mechanical parameters are identical. Both parts are from the same ECQ-E(F) series and maintain equivalent performance characteristics.

Q: Are there any compliance or regulatory differences?

A: No. Both parts carry identical compliance certifications: ROHS3 Compliant and REACH Unaffected status. Both are classified as Active products by Panasonic Electronic Components.

Q: Can I use a higher voltage rated capacitor as a substitute?

A: Substitution is based on exact parameter matching for the specified voltage rating. The ECQ-E4473KF at 400V DC is equivalent to the ECQ-E4473KFZ at 400V DC. Use only parts meeting the exact voltage specification required by your application.

Q: Does package size affect substitution eligibility?

A: Yes. Both parts share identical physical dimensions (12.00mm x 5.00mm), height (9.30mm maximum seated), and lead spacing (10.00mm). These mechanical parameters must match exactly for PCB compatibility and direct substitution.
