ECK-TFC152MF Equivalent & Substitute Parts

Part Overview

The ECK-TFC152MF is a 1500 pF ceramic capacitor rated for 250VAC with Y5V temperature coefficient, manufactured by Panasonic Electronic Components. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The part is designed for safety-rated applications requiring Y2 classification and operates across a temperature range of -25°C to 100°C in a nonstandard SMD package.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECK-TFC152MF is determined by the following critical parameters:

• Capacitance Value: Must be 1500 pF
• Voltage Rating: Must be rated for 250VAC minimum
• Safety Classification: Must maintain Y2 or equivalent safety rating for the intended application
• Mounting Type: Must be Surface Mount MLCC compatible with standard PCB assembly processes
• Moisture Sensitivity: MSL 1 rating ensures compatibility with standard handling and storage

The GA352QR7GF152KW01L from Murata Electronics meets these substitution criteria. While it features X7R temperature coefficient (superior stability compared to Y5V) and tighter ±10% tolerance, it maintains the required 1500 pF capacitance, 250VAC rating, and Y2 safety classification necessary for direct substitution in safety-rated applications.

Parameter Comparison

Engineering Selection Recommendations

The GA352QR7GF152KW01L is a direct functional substitute for the obsolete ECK-TFC152MF. Selection of this substitute is supported by:

• Product Availability: The Murata part is active in production with 2102 units in stock, compared to the Panasonic part's obsolete status
• Compliance: Both parts maintain REACH Unaffected status and EAR99 ECCN classification
• Safety Certification: Both parts carry Y2 safety rating, meeting the requirements of safety-rated applications
• Electrical Equivalence: Identical capacitance and voltage ratings ensure functional compatibility in the circuit
• Enhanced Performance: The X7R temperature coefficient provides superior capacitance stability across the operating temperature range compared to Y5V, with tighter tolerance specification

Physical package differences exist between the nonstandard SMD of the original part and the 2211 (5728 Metric) package of the substitute. PCB layout verification is necessary to confirm footprint compatibility before implementation.

Frequently Asked Questions (FAQ)

Q: Can the GA352QR7GF152KW01L replace the ECK-TFC152MF in all applications?

A: The GA352QR7GF152KW01L meets all electrical and safety requirements for substitution. However, the package format differs (2211 Metric vs. Nonstandard SMD), requiring PCB footprint verification before deployment.

Q: What is the difference between Y5V and X7R temperature coefficients?

A: Y5V exhibits greater capacitance variation across temperature (-82% to +22% over operating range), while X7R provides superior stability (±15% over -55°C to 125°C). For the ECK-TFC152MF application, X7R offers improved performance characteristics.

Q: Are both parts compliant with REACH regulations?

A: Yes, both the ECK-TFC152MF and GA352QR7GF152KW01L are REACH Unaffected, indicating compliance with current environmental regulations.

Q: What does MSL 1 (Unlimited) moisture sensitivity mean?

A: MSL 1 indicates the component has unlimited shelf life under standard storage conditions and requires no special moisture control during handling or assembly, simplifying logistics and manufacturing processes.

Q: Why is the Panasonic part listed as obsolete?

A: The ECK-TFC152MF has been discontinued by Panasonic. The Murata GA352QR7GF152KW01L remains in active production and serves as the recommended equivalent for new designs and ongoing supply requirements.
