ECQ-E1474KZ Equivalent & Substitute Parts

Part Overview

The ECQ-E1474KZ is a 0.47 µF film capacitor manufactured by Panasonic Electronic Components, rated for 100V DC operation with polyester metallized dielectric construction. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The radial through-hole configuration and ±10% tolerance specification define its primary application scope in general-purpose filtering and coupling circuits.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECQ-E1474KZ is determined by the following critical parameters:

• Capacitance Value: Must be 0.47 µF (exact match required)
• Tolerance: Must be ±10% or tighter
• Dielectric Type: Must be polyester metallized film
• Mounting Configuration: Must be through-hole radial
• Lead Spacing: Must be 0.591" (15.00mm) to ensure PCB compatibility
• Termination Type: Must be PC pins

The ECQ-E2474KF qualifies as a direct substitute based on these parameters. While the substitute part features enhanced voltage rating (250V DC versus 100V DC) and extended operating temperature range (-40°C ~ 105°C versus -40°C ~ 85°C), these represent performance improvements that do not compromise compatibility in applications designed for the original part's specifications.

Parameter Comparison

Engineering Selection Recommendations

The ECQ-E2474KF is the qualified substitute for ECQ-E1474KZ applications. Selection is justified on the following basis:

Product Status: The ECQ-E2474KF maintains active product status with current manufacturing support, whereas the ECQ-E1474KZ is obsolete. This ensures long-term availability and supply chain continuity.

Compliance Certifications: The ECQ-E2474KF is ROHS3 compliant and REACH unaffected, meeting modern regulatory requirements for electronic component procurement.

Electrical Compatibility: The substitute part maintains identical capacitance (0.47 µF), tolerance (±10%), dielectric composition (polyester metallized), and lead spacing (15.00mm). The elevated voltage rating (250V DC) and extended temperature range (-40°C ~ 105°C) provide operational margin without introducing incompatibility.

Physical Compatibility: Both parts share identical lead spacing and through-hole radial configuration, enabling direct PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can ECQ-E2474KF be used as a direct replacement for ECQ-E1474KZ?

A: Yes. The ECQ-E2474KF meets all substitution criteria: identical capacitance value (0.47 µF), matching tolerance (±10%), same dielectric material (polyester metallized), identical lead spacing (15.00mm), and compatible through-hole radial package configuration.

Q: What are the physical differences between these parts?

A: The ECQ-E2474KF has slightly larger dimensions (18.50mm L x 5.30mm W versus 17.00mm L x 5.50mm W) and greater seated height (14.60mm versus 12.00mm). Lead spacing remains identical at 15.00mm, ensuring PCB compatibility. Verify available board space before substitution.

Q: Does the higher voltage rating of ECQ-E2474KF affect circuit performance?

A: No. The 250V DC rating of the substitute part is a performance enhancement that does not alter electrical behavior in circuits designed for 100V operation. The part will function identically in the original application.

Q: Are there temperature range considerations for substitution?

A: The ECQ-E2474KF operates across -40°C ~ 105°C, compared to the original part's -40°C ~ 85°C range. This extended range provides additional operational margin and does not introduce compatibility issues.

Q: What compliance advantages does the substitute part offer?

A: The ECQ-E2474KF is ROHS3 compliant and REACH unaffected, meeting current regulatory standards. The original ECQ-E1474KZ compliance status is not specified. Modern procurement typically requires these certifications.
