Key Parameters

Substitute Part Grouping Explanation

The ECQ-E2823KF qualifies as a functional substitute based on the following critical parameters:

Matching Parameters:

• Capacitance: 0.082 µF (identical)
• Tolerance: ±10% (identical)
• Dielectric Material: Polyester (identical base material; ECQ-E2823KF uses metallized polyester, which is a compatible variant)
• Mounting Type: Through Hole (identical)
• Package / Case: Radial (identical)
• Termination: PC Pins (identical)
• Applications: General Purpose (identical)

Enhanced Parameters:

• Voltage Rating - DC: 250V (exceeds 200V requirement)
• Operating Temperature Range: -40°C ~ 105°C (exceeds -40°C ~ 85°C range)
• Product Status: Active (ensures ongoing availability)
• RoHS Compliance: ROHS3 Compliant (improved regulatory status)

The ECQ-E2823KF maintains electrical and mechanical compatibility while providing superior voltage margin and extended temperature capability. The metallized polyester dielectric is a direct advancement over standard polyester film technology for this capacitance and voltage class.

Parameter Comparison

Engineering Selection Recommendations

The ECQ-E2823KF is the appropriate substitute for ECQ-M2823KZ applications based on the following factors:

Availability & Compliance: The ECQ-M2823KZ is obsolete with no ongoing production. The ECQ-E2823KF is an active product with 12,084 units in stock, ensuring supply chain continuity. The ECQ-E2823KF meets ROHS3 compliance requirements, whereas the ECQ-M2823KZ does not.

Electrical Performance: The ECQ-E2823KF provides 250V DC rating against the original 200V requirement, delivering a 25% voltage safety margin. Both parts maintain identical capacitance (0.082 µF) and tolerance (±10%), ensuring circuit performance equivalence.

Thermal Capability: The ECQ-E2823KF operates across -40°C to 105°C, extending the upper temperature limit by 20°C compared to the ECQ-M2823KZ (-40°C to 85°C), providing improved thermal headroom for demanding applications.

Physical Considerations: Lead spacing differs between the two parts (15.00mm vs. 7.50mm). PCB layout modifications are required for the ECQ-E2823KF installation. Both maintain radial through-hole mounting with PC pin termination, ensuring mechanical compatibility with standard through-hole assembly processes.

Frequently Asked Questions (FAQ)

Q: Can ECQ-E2823KF directly replace ECQ-M2823KZ without circuit modification?

A: Electrical substitution is direct. The capacitance, tolerance, and voltage rating are compatible. However, the lead spacing differs (15.00mm vs. 7.50mm), requiring PCB layout adjustment. No circuit schematic changes are necessary.

Q: What is the significance of the metallized polyester dielectric in ECQ-E2823KF?

A: Metallized polyester is a standard advancement in film capacitor technology. It provides equivalent electrical performance to standard polyester film while enabling more compact packaging. For this 0.082 µF / 250V application, metallized polyester is a proven, reliable dielectric material.

Q: Does the higher voltage rating (250V vs. 200V) affect circuit operation?

A: No. A higher voltage rating does not change capacitance or circuit behavior. It provides additional safety margin and reliability in the application. The part operates identically at 200V or below.

Q: Is the extended temperature range (-40°C to 105°C vs. -40°C to 85°C) relevant for my application?

A: The extended range provides design flexibility for high-temperature environments. If your application operates within -40°C to 85°C, both parts perform equivalently. The ECQ-E2823KF offers additional thermal margin for future design iterations or harsh operating conditions.

Q: What compliance advantages does ECQ-E2823KF offer?

A: The ECQ-E2823KF is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronics manufacturing and distribution. The ECQ-M2823KZ is RoHS non-compliant, which may restrict its use in regulated markets or OEM supply chains.

Q: Are there any performance differences between the two parts in general-purpose applications?

A: Both parts are rated for general-purpose applications with identical capacitance and tolerance. The ECQ-E2823KF provides superior voltage and temperature margins without performance trade-offs, making it the preferred choice for new designs and replacements.
