Equivalent & Substitute Parts for ECQ-E1475KZ

Part Overview

The ECQ-E1475KZ is a 4.7 µF film capacitor rated at 100V DC with polyester metallized dielectric, manufactured by Panasonic Electronic Components in the ECQ-E(K) series. This part is classified as obsolete, making substitute components necessary for ongoing design support and procurement. The radial through-hole configuration and ±10% tolerance make it suitable for general-purpose applications requiring stable capacitance performance across the -40°C to 85°C operating range.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ECQ-E1475KZ is determined by the following critical parameters:

• Capacitance Value: Must be 4.7 µF
• Tolerance: Must be ±10%
• Dielectric Type: Must be polyester metallized film
• Mounting Configuration: Must be through-hole radial
• Termination Style: Must be PC pins
• Lead Spacing: Must accommodate 1.083" (27.50mm) spacing or be mechanically compatible

Substitute parts may exceed the original voltage rating (100V DC) while maintaining all other electrical and mechanical specifications. Higher voltage ratings provide design margin and are acceptable in applications originally specified for 100V operation.

Parameter Comparison

Engineering Selection Recommendations

ECQ-E2475KF (Panasonic Electronic Components): This substitute maintains manufacturer continuity within the Panasonic ECQ-E series and is actively produced. It provides 250V DC rating with extended operating temperature range to 105°C. The lead spacing of 0.886" (22.50mm) differs from the original 1.083" (27.50mm), requiring PCB layout verification before implementation. ROHS3 compliance is confirmed.

890273427005CS (Würth Elektronik): This substitute preserves the original lead spacing of 1.083" (27.50mm), enabling direct PCB compatibility without layout modification. The 250V DC rating and ROHS3 compliance are confirmed. Physical dimensions are comparable to the original part. This option is preferred when PCB layout changes must be minimized.

Both substitutes are actively produced and carry appropriate regulatory certifications. Selection between them depends on PCB layout constraints and supply chain preferences.

Frequently Asked Questions (FAQ)

Q: Can ECQ-E2475KF be used as a direct replacement for ECQ-E1475KZ?

A: Electrical substitution is valid. The 4.7 µF capacitance, ±10% tolerance, polyester metallized dielectric, and through-hole radial configuration are identical. However, the lead spacing differs (0.886" versus 1.083"), requiring PCB layout verification and potential trace rerouting.

Q: What is the impact of the higher voltage rating in substitute parts?

A: Both substitutes are rated at 250V DC compared to the original 100V DC. Higher voltage ratings do not degrade performance in 100V applications; they provide additional design margin and are electrically compatible.

Q: Is the 890273427005CS mechanically compatible without PCB modification?

A: Yes. The 890273427005CS maintains the original 1.083" (27.50mm) lead spacing, allowing direct PCB footprint compatibility. Physical dimensions are within acceptable tolerance of the original part.

Q: Are both substitutes RoHS compliant?

A: Yes. Both ECQ-E2475KF and 890273427005CS are ROHS3 compliant. RoHS compliance status was not specified for the original ECQ-E1475KZ.

Q: What is the temperature operating range difference?

A: The ECQ-E2475KF extends the upper operating temperature to 105°C compared to 85°C for both the original part and the 890273427005CS. This provides additional thermal margin in high-temperature applications.

Q: Can lead spacing differences affect circuit performance?

A: Lead spacing affects PCB layout only. Electrical performance is not impacted. However, PCB trace routing and component placement must accommodate the different spacing to avoid design conflicts.
