Key Parameters

Substitute Part Grouping Explanation

Substitution for the ECJ-0EF1E682Z is determined by the following mandatory parameters:

• Capacitance Value: 6800 pF (exact match required)
• Voltage Rating: 25V (minimum requirement; higher ratings acceptable)
• Package / Case: 0402 (1005 Metric) (physical compatibility required)
• Mounting Type: Surface Mount, MLCC (assembly compatibility required)

The GRM155R71E682KA01D from Murata Electronics meets all mandatory substitution criteria. While the temperature coefficient differs (X7R versus Y5V), both coefficients are standard ceramic capacitor classifications suitable for general purpose applications at the specified voltage and capacitance. The X7R coefficient provides a wider operating temperature range (-55°C ~ 125°C) compared to the Y5V specification (-30°C ~ 85°C).

Parameter Comparison

Engineering Selection Recommendations

The GRM155R71E682KA01D is the direct functional equivalent for the ECJ-0EF1E682Z based on matching capacitance, voltage rating, and 0402 package specifications. The substitute part offers improved RoHS3 compliance status, whereas the original part is RoHS non-compliant. The X7R temperature coefficient of the substitute provides a wider operating temperature range, which may be advantageous in applications requiring extended thermal performance beyond the original Y5V specification. The tighter tolerance (±10% versus -20%, +80%) of the substitute part offers improved capacitance stability. Both parts share identical MSL ratings and physical dimensions, ensuring direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can the GRM155R71E682KA01D replace the ECJ-0EF1E682Z in existing designs?

A: Yes. Both parts share identical capacitance (6800 pF), voltage rating (25V), and 0402 package dimensions. Physical and electrical compatibility is confirmed for direct substitution on PCBs designed for the original part.

Q: What is the significance of the temperature coefficient difference (Y5V versus X7R)?

A: Temperature coefficient designates how capacitance changes across operating temperature ranges. Y5V provides ±15% capacitance change from -30°C to 85°C. X7R provides ±15% capacitance change from -55°C to 125°C. For applications operating within the original -30°C to 85°C range, both coefficients are functionally equivalent. Applications requiring extended temperature operation benefit from the X7R specification.

Q: Does the tolerance difference affect substitution suitability?

A: The substitute part features tighter tolerance (±10% versus -20%, +80%). This provides improved capacitance accuracy and stability. Circuits designed for the wider tolerance of the original part remain compatible with the substitute's tighter tolerance.

Q: Are there packaging or moisture sensitivity concerns?

A: No. Both parts are rated MSL 1 (Unlimited moisture sensitivity), indicating no special moisture handling requirements. Physical dimensions and thickness are identical, confirming direct PCB compatibility without layout modifications.

Q: What is the significance of the RoHS compliance difference?

A: The original ECJ-0EF1E682Z is RoHS non-compliant, while the GRM155R71E682KA01D is ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the substitute part satisfies compliance requirements.
