Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECQ-E4823KZ is determined by the following critical parameters:

• Capacitance Value: Must be 0.082 µF (exact match required)
• Tolerance: ±10% (standard tolerance maintained)
• Dielectric Type: Polyester, Metallized (material class must match)
• Mounting Configuration: Through Hole, Radial package (physical form factor)
• Voltage Rating: Minimum 400V DC (equal or higher voltage rating acceptable)
• Termination Style: PC Pins (lead configuration)

The ECQ-E6823KF qualifies as a substitute because it maintains identical capacitance, tolerance, dielectric material, mounting type, and termination style. The higher voltage rating (630V DC vs. 400V DC) and extended operating temperature range represent enhanced specifications suitable for the original application.

Parameter Comparison

Engineering Selection Recommendations

The ECQ-E6823KF is the designated substitute for ECQ-E4823KZ applications. Selection is based on the following factors:

Product Status: The ECQ-E6823KF maintains Active product status, ensuring continued availability and manufacturing support, whereas the ECQ-E4823KZ is Obsolete.

Electrical Compatibility: The substitute maintains identical capacitance (0.082 µF) and tolerance (±10%), with voltage rating increased from 400V DC to 630V DC. This higher rating provides margin in the original circuit application.

Environmental Compliance: The ECQ-E6823KF is ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component procurement.

Physical Considerations: Lead spacing differs between parts (0.531" vs. 0.591"), requiring PCB layout verification. Overall dimensions show minor variations; physical fit must be confirmed for the target application.

Frequently Asked Questions (FAQ)

Q: Can ECQ-E6823KF directly replace ECQ-E4823KZ without circuit modification?

A: Electrical substitution is valid. The higher voltage rating (630V vs. 400V) and extended temperature range (-40°C to 105°C vs. -40°C to 85°C) are compatible with the original application. Physical fit requires verification due to different lead spacing (0.591" vs. 0.531") and dimensional variations.

Q: What is the significance of the different lead spacing?

A: Lead spacing of 0.591" (ECQ-E6823KF) versus 0.531" (ECQ-E4823KZ) affects PCB hole positioning. PCB layout must accommodate the substitute's lead spacing to ensure proper mounting and electrical connection.

Q: Are there compliance differences between these parts?

A: The ECQ-E6823KF is ROHS3 Compliant and REACH Unaffected. The ECQ-E4823KZ compliance status is not specified. For applications requiring regulatory compliance documentation, the substitute provides certified compliance.

Q: Does the higher voltage rating affect circuit performance?

A: No. A component rated for higher voltage than required operates within specification. The 630V rating of ECQ-E6823KF exceeds the 400V requirement, providing additional safety margin without altering circuit function.

Q: What is the impact of the extended operating temperature range?

A: The ECQ-E6823KF operates to 105°C versus 85°C for the original part. This extended range provides greater thermal margin in applications approaching the upper temperature limit.
