ECQ-E10102KE Equivalent & Substitute Parts

Part Overview

The ECQ-E10102KE is a 1000 pF film capacitor rated for 1000V DC, manufactured by Panasonic Electronic Components as part of the ECQ-E(F) series. This radial polyester metallized film capacitor is designed for general-purpose applications requiring high voltage performance. The part is classified as obsolete, making identification of functionally equivalent substitutes essential for ongoing system maintenance and new design implementations where legacy component specifications must be maintained.

Substitute Part Grouping Explanation

Substitution of the ECQ-E10102KE is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 1000 pF (exact match required)
• DC Voltage Rating: 1000V minimum (equal or higher acceptable)
• Dielectric Type: Polyester, Metallized (material compatibility)
• Mounting Configuration: Through Hole, Radial package with PC Pins termination
• Physical Dimensions: Lead spacing 0.492" (12.50mm) for PCB compatibility
• Temperature Range: -40°C ~ 105°C operating specification
• Regulatory Compliance: ROHS3 Compliant status

The ECQ-E10102KF meets all substitution criteria as a direct functional equivalent within the same ECQ-E(F) series.

Parameter Comparison

Engineering Selection Recommendations

The ECQ-E10102KF is a direct parametric equivalent to the ECQ-E10102KE. Both components share identical capacitance, DC voltage rating, dielectric composition, physical dimensions, and lead spacing. Both maintain ROHS3 compliance and operate within the same temperature range. The ECQ-E10102KF includes an AC voltage rating specification (125V) not listed for the main part, which does not restrict its use in DC-primary applications. Given the obsolete status of both parts, the ECQ-E10102KF is suitable for direct substitution in applications currently specified for the ECQ-E10102KE.

Frequently Asked Questions (FAQ)

Q: Can the ECQ-E10102KF replace the ECQ-E10102KE in existing designs?

A: Yes. Both parts are identical in capacitance (1000 pF), DC voltage rating (1000V), dielectric material (polyester metallized), physical dimensions, and lead spacing. They are interchangeable for through-hole PCB applications.

Q: What is the significance of the AC voltage rating on the ECQ-E10102KF?

A: The ECQ-E10102KF specifies 125V AC rating, while the ECQ-E10102KE does not list an AC specification. This additional parameter does not affect DC circuit performance and does not restrict substitution in DC applications.

Q: Are there any packaging differences between these parts?

A: The ECQ-E10102KE is specified with standard packaging, while the ECQ-E10102KF is supplied in bulk packaging. Both use identical radial through-hole packages with PC pin termination and 12.50mm lead spacing.

Q: Do both parts meet current regulatory requirements?

A: Both the ECQ-E10102KE and ECQ-E10102KF are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component use.

Q: What is the lead spacing requirement for PCB design?

A: Both parts require 0.492" (12.50mm) lead spacing for proper PCB pad layout and component mounting.
