ECQ-E10104KF Equivalent & Substitute Parts

Part Overview

The ECQ-E10104KF is a 0.1 µF film capacitor manufactured by Panasonic Electronic Components, rated for 1000V DC operation with polyester metallized dielectric construction. This radial through-hole component is designed for general-purpose applications requiring high voltage performance. The part is currently active in production with full RoHS3 compliance and REACH unaffected status. Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when inventory constraints require component flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECQ-E10104KF is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.1 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 1000V minimum (equal or higher acceptable)
• Dielectric Material: Polyester, Metallized (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Lead Spacing: 0.689" (17.50mm) (exact match required)
• Termination: PC Pins (exact match required)

The substitute part DME10P1K-F meets all substitution criteria. While it features enhanced AC voltage rating (250V vs. 125V) and extended operating temperature range (-55°C to 125°C vs. -40°C to 105°C), these represent performance improvements that do not compromise compatibility or circuit functionality.

Parameter Comparison

Engineering Selection Recommendations

Both the ECQ-E10104KF and DME10P1K-F are active production components with full regulatory compliance. Selection between these parts should be based on availability and supply chain requirements. The DME10P1K-F offers enhanced performance specifications (higher AC voltage rating and extended temperature range) without introducing any compatibility constraints. Both components maintain identical RoHS3 and REACH compliance status, ensuring regulatory consistency across design revisions or production batches.

Frequently Asked Questions (FAQ)

Q: Can DME10P1K-F be used as a direct replacement for ECQ-E10104KF in existing designs?

A: Yes. The DME10P1K-F meets all electrical and mechanical substitution criteria. Identical capacitance, tolerance, DC voltage rating, dielectric material, mounting type, package configuration, and lead spacing ensure direct compatibility. The 0.5mm height difference (21.50mm vs. 21.00mm) falls within standard PCB layout tolerances.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution requires exact equivalence in capacitance (0.1 µF), tolerance (±10%), DC voltage rating (1000V minimum), dielectric material (polyester metallized), mounting type (through hole), package type (radial), lead spacing (0.689"), and termination style (PC pins). Deviations in any of these parameters disqualify a component from direct substitution.

Q: Does the higher AC voltage rating of DME10P1K-F affect circuit performance?

A: No. Higher voltage ratings represent enhanced component capability and do not negatively impact circuit operation. The DME10P1K-F operates safely in all applications designed for the ECQ-E10104KF.

Q: Are there any compliance or certification differences between these parts?

A: No. Both components are RoHS3 compliant and REACH unaffected, ensuring identical regulatory status for design documentation and supply chain requirements.

Q: How does the extended temperature range of DME10P1K-F affect suitability?

A: The wider operating temperature range (-55°C to 125°C vs. -40°C to 105°C) provides additional design margin in temperature-sensitive applications. This represents an improvement with no compatibility constraints.
