ECQ-E2103RKF Film Capacitor Equivalent & Substitute Parts

Part Overview

The ECQ-E2103RKF is a 10000 pF film capacitor manufactured by Panasonic Electronic Components, rated for 250V DC operation with polyester metallized dielectric construction. This radial through-hole component is designed for general-purpose applications requiring stable capacitance and reliable performance across industrial temperature ranges. The part maintains Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when packaging configurations, inventory availability, or specific application constraints necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECQ-E2103RKF is determined by strict equivalence across the following critical parameters:

• Capacitance value: 10000 pF (exact match required)
• Tolerance: ±10% (exact match required)
• DC voltage rating: 250V minimum (equal or higher acceptable)
• Dielectric material: Polyester, Metallized (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• Mounting type: Through Hole (exact match required)
• Package configuration: Radial (exact match required)
• Lead spacing: 0.295" (7.50mm) (exact match required)
• Termination style: PC Pins (exact match required)
• Compliance certifications: RoHS3 Compliant, REACH Unaffected (exact match required)

The ECQ-E2103KF qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Packaging format differences (Tape & Box versus Bulk) do not affect functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both ECQ-E2103RKF and ECQ-E2103KF maintain Active product status with identical RoHS3 compliance and REACH unaffected certifications, ensuring regulatory alignment for current and future applications. Selection between these parts should be based on:

• Packaging requirements: ECQ-E2103RKF is supplied in Tape & Box format; ECQ-E2103KF is supplied in Bulk format
• Physical space constraints: ECQ-E2103KF provides a lower seated height (0.331" versus 0.488"), which may be advantageous in compact PCB layouts
• Inventory availability: Current stock levels differ (944 pcs for ECQ-E2103RKF; 1575 pcs for ECQ-E2103KF)
• Supply chain continuity: Both parts share identical base product number (ECQ-E2103) and series designation, ensuring long-term sourcing stability

No functional performance differences exist between these parts for DC voltage applications at 250V or below.

Frequently Asked Questions (FAQ)

Q: Can ECQ-E2103KF be used as a direct replacement for ECQ-E2103RKF in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 10000 pF capacitance, ±10% tolerance, 250V DC rating, polyester metallized dielectric, -40°C to 105°C operating range, radial through-hole configuration, and 7.50mm lead spacing. The only differences are packaging format and seated height.

Q: What is the significance of the different seated heights (12.40mm versus 8.40mm)?

A: Seated height affects PCB layout clearance and component density. The ECQ-E2103KF's lower profile (8.40mm) may be preferred for applications with vertical space constraints or higher component density requirements. Both heights are compatible with standard through-hole PCB designs.

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

A: No. Both ECQ-E2103RKF and ECQ-E2103KF carry identical RoHS3 compliance and REACH unaffected status, ensuring regulatory equivalence for all applications.

Q: Does packaging format (Tape & Box versus Bulk) affect electrical performance?

A: No. Packaging format is a logistics and handling consideration only. It does not affect the electrical characteristics, reliability, or performance of the capacitor in circuit operation.

Q: What determines substitution eligibility for this capacitor series?

A: Substitution requires exact matching of capacitance value, tolerance, DC voltage rating, dielectric material, operating temperature range, mounting type, package configuration, lead spacing, termination style, and compliance certifications. Deviations in any of these parameters disqualify a part from direct substitution.
