ECQ-M2333KZ Equivalent & Substitute Parts

Part Overview

The ECQ-M2333KZ is a 0.033 µF film capacitor rated for 200V DC operation with polyester dielectric material and radial through-hole mounting. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The ECQ-M series has been superseded by newer product lines with enhanced specifications and active manufacturing status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECQ-M2333KZ is determined by the following critical parameters:

• Capacitance Value: Must match exactly at 0.033 µF
• Voltage Rating - DC: Substitute must meet or exceed 200V DC rating
• Tolerance: Must maintain ±10% tolerance specification
• Dielectric Material: Polyester-based dielectric acceptable
• Mounting Type: Through-hole radial configuration required
• Termination: PC pin termination required for PCB compatibility

The ECQ-E2333KF qualifies as a direct substitute based on these parameters. While it features a higher voltage rating (250V DC) and metallized polyester dielectric, these represent improvements over the original specification and do not compromise compatibility in applications designed for the ECQ-M2333KZ.

Engineering Selection Recommendations

The ECQ-E2333KF is the qualified substitute for the obsolete ECQ-M2333KZ. Selection is based on the following factors:

• Product Status: The ECQ-E2333KF maintains active manufacturing status, ensuring long-term availability and supply chain continuity.
• Compliance: The substitute meets ROHS3 compliance requirements, addressing modern regulatory standards not specified for the obsolete ECQ-M series.
• Electrical Compatibility: The substitute exceeds the original voltage specification (250V DC vs. 200V DC), providing enhanced safety margin in the application circuit.
• Temperature Performance: The extended operating range (-40°C ~ 105°C) accommodates broader environmental conditions compared to the original part (-40°C ~ 85°C).
• Physical Compatibility: Both parts maintain radial through-hole configuration with PC pin termination, ensuring PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can the ECQ-E2333KF be used as a direct replacement for the ECQ-M2333KZ?

A: Yes. Both parts share identical capacitance (0.033 µF), tolerance (±10%), and mounting configuration (radial through-hole with PC pins). The substitute meets or exceeds all critical electrical parameters of the original part.

Q: What is the difference in physical size between these parts?

A: The ECQ-E2333KF has a smaller footprint (0.406" L x 0.177" W, 10.30mm x 4.50mm) with reduced lead spacing (0.295" / 7.50mm) compared to the ECQ-M2333KZ lead spacing (0.492" / 12.50mm). PCB layout verification is required to confirm physical compatibility in the target application.

Q: Why does the ECQ-E2333KF have a higher voltage rating?

A: The ECQ-E series represents a newer product generation with improved specifications. The 250V DC rating (versus 200V DC) provides additional safety margin and does not negatively impact applications designed for the original 200V specification.

Q: Is the metallized polyester dielectric in the ECQ-E2333KF compatible with the original polyester specification?

A: Yes. Metallized polyester is a standard evolution of polyester film capacitor technology and maintains functional equivalence for general-purpose applications. Both materials are polyester-based with identical capacitance and tolerance characteristics.

Q: What compliance certifications apply to the substitute part?

A: The ECQ-E2333KF is ROHS3 compliant and REACH unaffected. These certifications address current regulatory requirements for electronic components in regulated markets.
