Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECQ-E6224KZ is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 0.22 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 630V (minimum requirement; higher ratings acceptable)
• Dielectric Material: Polyester, Metallized (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Termination: PC Pins (exact match required)

The ECQ-E6224KF meets all substitution criteria. Physical dimensions and lead spacing may vary within acceptable mechanical tolerances for through-hole mounting applications, provided the component fits within the designated PCB footprint.

Parameter Comparison

Engineering Selection Recommendations

The ECQ-E6224KF is the direct functional equivalent for the obsolete ECQ-E6224KZ. Both components share identical electrical specifications for capacitance, tolerance, DC voltage rating, and dielectric material. The ECQ-E6224KF offers the following advantages:

• Active Product Status: Currently manufactured by Panasonic Electronic Components, ensuring long-term availability and supply chain stability.
• Extended Operating Temperature: Upper temperature limit of 105°C versus 85°C provides additional thermal margin in high-temperature environments.
• Compliance Certifications: ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.
• Compact Form Factor: Smaller physical dimensions (18.50mm x 9.00mm) reduce PCB space requirements compared to the original part.

Critical Consideration: Lead spacing differs between the two parts (25.50mm versus 15.00mm). PCB footprint verification is mandatory before component substitution to ensure mechanical fit and electrical connection integrity.

Frequently Asked Questions (FAQ)

Q: Can the ECQ-E6224KF be used as a direct replacement for the ECQ-E6224KZ?

A: Electrically, yes. Both components have identical capacitance (0.22 µF), tolerance (±10%), and DC voltage rating (630V). However, lead spacing differs (25.50mm versus 15.00mm), requiring PCB footprint verification before substitution.

Q: Why is the ECQ-E6224KZ classified as obsolete?

A: The ECQ-E6224KZ has been discontinued by Panasonic Electronic Components. The ECQ-E6224KF represents the current active equivalent in the ECQ-E series.

Q: Does the extended operating temperature range of the ECQ-E6224KF affect compatibility?

A: No. The extended range (-40°C ~ 105°C versus -40°C ~ 85°C) is a performance enhancement that maintains full compatibility with applications designed for the original part's temperature specifications.

Q: Are there compliance differences between the two parts?

A: The ECQ-E6224KF is ROHS3 compliant and REACH unaffected. The ECQ-E6224KZ compliance status is not specified. For applications requiring current regulatory compliance, the ECQ-E6224KF is the appropriate selection.

Q: What is the impact of the smaller physical dimensions of the ECQ-E6224KF?

A: The substitute is physically smaller (18.50mm x 9.00mm versus 29.00mm x 8.50mm), which reduces PCB space requirements. This is advantageous for compact designs but requires verification that the component fits within the designated mounting area.

Q: How should lead spacing differences be addressed in PCB design?

A: Lead spacing must be verified against the PCB footprint before component substitution. If the original PCB is designed for 25.50mm spacing and the substitute uses 15.00mm spacing, mechanical rework or PCB redesign may be necessary.
