Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECQ-E4564KZ is determined by the following critical parameters:

• Capacitance Value: Must be 0.56 µF (exact match required)
• Tolerance: Must be ±10% or tighter
• Voltage Rating - DC: Must be equal to or greater than 400V
• Dielectric Material: Must be polyester metallized construction
• Mounting Type: Must be through-hole radial configuration
• Termination Style: Must use PC pins

The ECQ-E6564KF meets all substitution criteria. While it features a higher voltage rating (630V DC) and extended operating temperature range (-40°C ~ 105°C), these represent performance enhancements rather than deviations. Physical dimensions differ slightly due to the higher voltage rating, requiring verification of board layout compatibility.

Parameter Comparison

Engineering Selection Recommendations

The ECQ-E6564KF is a direct functional substitute for the obsolete ECQ-E4564KZ. The substitute part maintains identical capacitance and tolerance specifications while providing enhanced voltage and temperature performance margins. The ECQ-E6564KF is classified as active product status with ROHS3 compliance and REACH unaffected certification, ensuring long-term availability and regulatory alignment.

Physical dimension differences require board layout verification prior to implementation. The substitute part features reduced length (26.00mm vs. 29.00mm) and modified lead spacing (22.50mm vs. 25.50mm), with increased seated height (21.00mm vs. 18.50mm). These variations necessitate confirmation of PCB footprint compatibility and clearance requirements in the target application.

Frequently Asked Questions (FAQ)

Q: Can ECQ-E6564KF be used as a direct replacement for ECQ-E4564KZ?

A: Yes. Both components share identical capacitance (0.56 µF) and tolerance (±10%) specifications. The substitute part exceeds the voltage rating requirement (630V vs. 400V) and extends the operating temperature range. Physical dimensions differ and must be verified against PCB layout constraints.

Q: What are the key differences between these parts?

A: The primary differences are voltage rating (630V vs. 400V), operating temperature range (-40°C ~ 105°C vs. -40°C ~ 85°C), and physical dimensions. The ECQ-E6564KF is smaller in length but taller in seated height with different lead spacing.

Q: Does the higher voltage rating of ECQ-E6564KF affect circuit performance?

A: No. A higher voltage rating does not degrade performance in circuits designed for lower voltages. The substitute part operates safely at 400V and below.

Q: Are there any compliance or certification differences?

A: The ECQ-E6564KF carries ROHS3 compliance and REACH unaffected certification. The original ECQ-E4564KZ is obsolete. The substitute part ensures regulatory compliance for new designs and ongoing production.

Q: What must be verified before implementing the substitute part?

A: PCB footprint compatibility is critical. Verify that the modified lead spacing (22.50mm vs. 25.50mm) and increased seated height (21.00mm vs. 18.50mm) accommodate the physical constraints of the target application.
