Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECQ-E4153KZ is determined by the following critical parameters:

• Capacitance Value: Must match exactly at 0.015 µF
• Tolerance: Must be ±10% or tighter
• Dielectric Type: Polyester, Metallized construction required
• Mounting Configuration: Through-hole radial package with PC pin termination
• Voltage Rating: Substitute must meet or exceed the 400V DC requirement
• Lead Spacing: Physical compatibility with 10.50mm nominal spacing

The ECQ-E6153KF qualifies as a direct substitute based on matching capacitance, tolerance, dielectric material, mounting type, and package configuration. The substitute provides enhanced voltage rating (630V DC) and extended operating temperature range (-40°C ~ 105°C), making it suitable for applications requiring the original ECQ-E4153KZ specifications.

Engineering Selection Recommendations

The ECQ-E6153KF is the qualified substitute for the obsolete ECQ-E4153KZ. Selection is based on:

• Functional Equivalence: Identical capacitance and tolerance specifications ensure electrical performance parity in DC link, DC filtering, high frequency switching, and high pulse DV/DT applications.
• Enhanced Ratings: The 630V DC rating of the ECQ-E6153KF exceeds the 400V requirement of the original part, providing operational margin in the target application.
• Compliance Status: The ECQ-E6153KF is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for new designs and system updates.
• Active Product Status: The ECQ-E6153KF is currently in active production, ensuring long-term availability and supply chain continuity.
• Physical Compatibility: Lead spacing and mounting configuration are compatible with existing PCB layouts designed for the ECQ-E4153KZ, with minor dimensional variations within acceptable tolerances.

Frequently Asked Questions (FAQ)

Q: Can the ECQ-E6153KF be used as a direct replacement for the ECQ-E4153KZ in existing designs?

A: Yes. Both parts share identical capacitance (0.015 µF), tolerance (±10%), dielectric material (polyester metallized), and mounting configuration (through-hole radial). The ECQ-E6153KF provides higher voltage rating (630V vs. 400V) and extended temperature range (-40°C to 105°C vs. -40°C to 85°C), making it functionally equivalent and suitable for the same applications.

Q: What are the physical differences between these parts?

A: The ECQ-E6153KF has slightly different dimensions (12.00mm x 5.00mm vs. 14.60mm x 4.50mm) and lead spacing (10.00mm vs. 10.50mm). These variations are minor and typically accommodate standard PCB hole patterns. Height differences (9.20mm vs. 9.00mm) are negligible for most applications.

Q: Why is the ECQ-E4153KZ obsolete?

A: The ECQ-E4153KZ has been discontinued by Panasonic Electronic Components. The ECQ-E6153KF represents the current active equivalent in the ECQ-E series, offering improved specifications and regulatory compliance.

Q: Are there compliance differences between the two parts?

A: The ECQ-E6153KF is ROHS3 compliant and REACH unaffected, meeting modern environmental and regulatory standards. The ECQ-E4153KZ compliance status is not specified. For new designs and systems requiring regulatory certification, the ECQ-E6153KF is the appropriate choice.

Q: What applications are these capacitors suitable for?

A: Both parts are designed for DC link, DC filtering, high frequency switching, and high pulse DV/DT applications. The enhanced voltage rating of the ECQ-E6153KF provides additional operational flexibility in demanding switching and filtering circuits.
