ECK-TFC471KB Equivalent & Substitute Parts

Part Overview

The ECK-TFC471KB is a 470 pF ceramic capacitor rated for 250VAC with Y5P temperature coefficient, manufactured by Panasonic Electronic Components. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement continuity. The part is designed for safety-rated applications requiring nonstandard SMD packaging with unlimited moisture sensitivity level (MSL 1).

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECK-TFC471KB is determined by strict alignment of the following critical parameters:

• Capacitance Value: 470 pF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating: 250V minimum (equal or higher acceptable)
• Temperature Coefficient: Y5P or equivalent performance class (X7R acceptable for extended temperature range)
• Mounting Type: Surface Mount MLCC (required)
• Safety Rating: Y2 classification (required for safety applications)
• Moisture Sensitivity: MSL 1 or better (required)

The substitute part GA352QR7GF471KW01L meets these criteria with equivalent electrical performance and enhanced temperature stability through X7R coefficient, while maintaining safety-rated Y2 classification and MSL 1 moisture sensitivity.

Parameter Comparison

Engineering Selection Recommendations

The GA352QR7GF471KW01L from Murata Electronics is a direct functional substitute for the obsolete ECK-TFC471KB. Both components meet identical electrical specifications for capacitance, tolerance, and voltage rating. The substitute provides enhanced performance through X7R temperature coefficient, which offers superior stability across the extended operating range of -55°C to 125°C compared to the original Y5P specification.

The substitute maintains full compliance with safety-rated Y2 classification and REACH regulations. Both components carry MSL 1 rating, eliminating moisture sensitivity concerns. The substitute is currently in active production status with 2630 units available in inventory, ensuring procurement reliability.

Physical dimensions differ slightly: the substitute is more compact in width (2.80mm vs 4.50mm) and thickness (1.50mm vs 2.30mm), which may require PCB layout verification to confirm mechanical compatibility within the original design footprint.

Frequently Asked Questions (FAQ)

Q: Can GA352QR7GF471KW01L be used as a direct replacement for ECK-TFC471KB?

A: Yes. Both components share identical capacitance (470 pF), tolerance (±10%), and voltage rating (250VAC). The substitute meets all electrical requirements for safety-rated applications with Y2 classification and MSL 1 moisture sensitivity.

Q: What is the difference between Y5P and X7R temperature coefficients?

A: Y5P provides ±10% capacitance change over -25°C to 100°C. X7R provides ±15% capacitance change over -55°C to 125°C. X7R offers wider temperature range and more predictable performance characteristics, making it suitable for applications requiring extended thermal stability.

Q: Will the physical size difference affect PCB compatibility?

A: The substitute is smaller in width and thickness. Verify that the PCB footprint and component placement accommodate the reduced dimensions (5.70mm L x 2.80mm W x 1.50mm thickness). If the original design requires the larger nonstandard SMD footprint, mechanical compatibility must be confirmed before implementation.

Q: Are both components RoHS compliant?

A: The main part (ECK-TFC471KB) status is not specified. The substitute (GA352QR7GF471KW01L) is ROHS3 compliant. Both are REACH unaffected and carry EAR99 ECCN classification.

Q: What is the inventory status for each part?

A: ECK-TFC471KB: 696 units available (obsolete status). GA352QR7GF471KW01L: 2630 units available (active production). The substitute offers superior long-term procurement availability.

Q: Are there any safety rating differences?

A: The main part carries Y2 safety rating. The substitute carries both X1 and Y2 ratings, providing broader safety classification coverage for different application requirements.
