• Capacitance Match: Both parts are rated 0.47 µF
• Tolerance Match: Both maintain ±10% tolerance
• Voltage Rating Match: Both rated 630V DC
• Dielectric Material Match: Both use polyester metallized construction
• Mounting Configuration Match: Both feature radial through-hole mounting with PC pin termination
• Base Product Number: Both share the same base product number ECQ-E6474, confirming functional equivalence

The ECQ-E6474KF represents an active production variant with improved specifications and compliance certifications, making it the recommended substitute for the obsolete ECQ-E6474KZ.

Parameter Comparison

Engineering Selection Recommendations

The ECQ-E6474KF is the appropriate substitute for the obsolete ECQ-E6474KZ. Both components share identical electrical specifications: 0.47 µF capacitance, ±10% tolerance, and 630V DC rating with polyester metallized dielectric construction.

The ECQ-E6474KF offers enhanced compliance certifications including ROHS3 compliance and REACH unaffected status, supporting modern regulatory requirements. The substitute maintains full functional compatibility with the original part across all critical electrical parameters.

Physical dimensions differ slightly: the ECQ-E6474KF is more compact (26.00mm x 9.30mm versus 29.00mm x 12.50mm) with reduced lead spacing (22.50mm versus 25.50mm). These dimensional changes require PCB layout verification to ensure mechanical fit within existing designs. The extended operating temperature range of the ECQ-E6474KF (-40°C ~ 105°C versus -40°C ~ 85°C) provides additional thermal margin for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the ECQ-E6474KF directly replace the ECQ-E6474KZ without circuit modification?

A: Electrical substitution is direct. Both parts maintain identical capacitance, tolerance, voltage rating, and dielectric material. PCB layout verification is required due to dimensional and lead spacing differences.

Q: What are the key dimensional differences between these parts?

A: The ECQ-E6474KF is physically smaller with dimensions of 26.00mm x 9.30mm compared to 29.00mm x 12.50mm for the ECQ-E6474KZ. Lead spacing is reduced from 25.50mm to 22.50mm. Verify PCB hole spacing and component clearances before substitution.

Q: Does the ECQ-E6474KF meet current regulatory requirements?

A: Yes. The ECQ-E6474KF is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards. The ECQ-E6474KZ status for these certifications is not specified.

Q: Are there any temperature rating considerations for substitution?

A: The ECQ-E6474KF operates across -40°C ~ 105°C, providing a 20°C higher upper temperature limit compared to the ECQ-E6474KZ (-40°C ~ 85°C). This extended range is beneficial for high-temperature applications.

Q: What is the AC voltage rating difference?

A: The ECQ-E6474KZ does not specify an AC voltage rating. The ECQ-E6474KF is rated 250V AC. For AC applications, the ECQ-E6474KF provides explicit AC voltage specification.
