Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECQ-E1184KZ is determined by the following critical parameters:

• Capacitance Value: Must remain 0.18 µF (no tolerance deviation acceptable for direct substitution)
• Tolerance: Must maintain ±10% specification
• Dielectric Type: Polyester, metallized construction required
• Mounting Configuration: Through-hole radial package with 0.394" (10.00mm) lead spacing
• Termination Style: PC pins required for PCB compatibility

The ECQ-E2184KF qualifies as a functional substitute based on matching capacitance, tolerance, dielectric material, mounting type, and lead spacing. The substitute part provides enhanced electrical performance through higher voltage rating (250V DC vs. 100V DC) and extended operating temperature range (-40°C ~ 105°C vs. -40°C ~ 85°C), with active product status and RoHS3 compliance.

Engineering Selection Recommendations

The ECQ-E2184KF is the qualified substitute for ECQ-E1184KZ applications. Selection is based on the following engineering criteria:

• Product Continuity: ECQ-E2184KF maintains active product status, ensuring long-term availability and supply chain stability compared to the obsolete ECQ-E1184KZ.
• Regulatory Compliance: ECQ-E2184KF achieves RoHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for new designs and production.
• Electrical Compatibility: Identical capacitance (0.18 µF), tolerance (±10%), and dielectric material (polyester, metallized) ensure functional equivalence in circuit operation.
• Physical Compatibility: Matching lead spacing (0.394" / 10.00mm), radial through-hole package, and PC pin termination provide direct PCB footprint compatibility without layout modification.
• Performance Enhancement: Higher voltage rating (250V DC) and extended operating temperature range (-40°C ~ 105°C) provide design margin and operational flexibility beyond the original specification.

Frequently Asked Questions (FAQ)

Q: Can ECQ-E2184KF be used as a direct replacement for ECQ-E1184KZ in existing designs?

A: Yes. The substitute part maintains identical capacitance (0.18 µF), tolerance (±10%), dielectric material (polyester, metallized), lead spacing (0.394" / 10.00mm), and radial through-hole package configuration. No PCB layout or schematic modifications are required.

Q: What are the key differences between ECQ-E1184KZ and ECQ-E2184KF?

A: The primary differences are voltage rating (100V DC vs. 250V DC), operating temperature range (-40°C ~ 85°C vs. -40°C ~ 105°C), product status (obsolete vs. active), and regulatory compliance (RoHS non-compliant vs. RoHS3 compliant). Physical dimensions show minor variation in width (0.177" vs. 0.197") and height (0.433" vs. 0.445").

Q: Are there any circuit performance implications when substituting ECQ-E2184KF for ECQ-E1184KZ?

A: No. Identical capacitance and tolerance values ensure equivalent circuit performance. The higher voltage rating of ECQ-E2184KF provides additional design margin without affecting capacitive behavior in the application.

Q: Does the physical size difference between these parts affect PCB compatibility?

A: Lead spacing remains identical at 0.394" (10.00mm), ensuring PCB footprint compatibility. Minor dimensional variations in length, width, and height do not impact through-hole mounting or electrical connection.

Q: What is the compliance status of each part?

A: ECQ-E1184KZ is RoHS non-compliant. ECQ-E2184KF is RoHS3 compliant and REACH unaffected, meeting current environmental regulations for new production and design implementations.
