Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECQ-E4683KZ is determined by strict equivalence in the following parameters:

• Capacitance Value: 0.068 µF (exact match required)
• Tolerance: ±10% (matching tolerance band)
• Dielectric Type: Polyester, Metallized (material consistency)
• Mounting Configuration: Through Hole, Radial (physical and electrical interface compatibility)
• Termination Style: PC Pins (board connection method)

The ECQ-E6683KF qualifies as a substitute based on matching all core electrical and mechanical parameters. The substitute component exhibits higher voltage rating (630V DC versus 400V DC) and extended operating temperature range (-40°C ~ 105°C versus -40°C ~ 85°C), both of which represent performance enhancements compatible with the original application requirements.

Parameter Comparison

Engineering Selection Recommendations

The ECQ-E6683KF is a direct functional substitute for the ECQ-E4683KZ. Both components are manufactured by Panasonic Electronic Components and share identical capacitance, tolerance, dielectric material, and mounting configuration. The substitute component is currently in active production status, ensuring long-term availability and supply chain continuity.

The ECQ-E6683KF provides enhanced electrical performance through higher voltage rating (630V DC) and extended operating temperature range (105°C maximum), making it suitable for applications requiring the original 400V specification. The substitute carries ROHS3 compliance and REACH unaffected status, meeting modern regulatory requirements.

Physical dimensions differ slightly between the two components. The ECQ-E6683KF exhibits increased length (18.50mm versus 16.50mm) and lead spacing (15.00mm versus 14.60mm), while seated height is reduced (12.00mm versus 13.00mm). PCB layout verification is required to confirm mechanical compatibility in the target application.

Frequently Asked Questions (FAQ)

Q: Can the ECQ-E6683KF replace the ECQ-E4683KZ in all applications?

A: The ECQ-E6683KF matches the core electrical specifications (0.068 µF capacitance, ±10% tolerance, polyester metallized dielectric, through-hole radial configuration). Physical dimensions differ, requiring PCB layout verification. The higher voltage rating and extended temperature range of the substitute are compatible with applications designed for the original component.

Q: What are the key differences between these two capacitors?

A: The primary differences are voltage rating (630V versus 400V), operating temperature range (-40°C ~ 105°C versus -40°C ~ 85°C), physical dimensions, and product status (active versus obsolete). Capacitance, tolerance, dielectric material, and termination style are identical.

Q: Does the ECQ-E6683KF fit the same PCB footprint as the ECQ-E4683KZ?

A: No. The lead spacing differs (15.00mm versus 14.60mm), and overall dimensions vary. PCB layout must be reviewed to confirm mechanical fit. The radial through-hole configuration remains compatible, but hole spacing must match the substitute component specifications.

Q: Are there compliance or regulatory differences between these parts?

A: The ECQ-E6683KF carries ROHS3 compliance and REACH unaffected status. The ECQ-E4683KZ compliance information is not provided in the available data. For applications requiring specific regulatory certifications, compliance documentation should be verified with the manufacturer.

Q: Why is the ECQ-E4683KZ obsolete?

A: The ECQ-E4683KZ is classified as obsolete by Panasonic Electronic Components. The ECQ-E6683KF represents the active equivalent in the ECQ-E series, offering improved specifications and continued manufacturing support.
