ECQ-M2183KZ Equivalent & Substitute Parts

Part Overview

The ECQ-M2183KZ is a 0.018 µF film capacitor rated for 200V DC operation with polyester dielectric material and radial through-hole mounting. Manufactured by Panasonic Electronic Components, this component is classified as obsolete. Due to its obsolete status and limited availability relative to active alternatives, identifying equivalent substitute parts is essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ECQ-M2183KZ are identified based on the following critical parameters that determine functional equivalence:

• Capacitance Value: Must match exactly at 0.018 µF
• Tolerance: Must be ±10% or tighter
• Voltage Rating - DC: Must be equal to or greater than 200V
• Dielectric Material: Polyester or metallized polyester acceptable
• Mounting Type: Through hole radial configuration required
• Termination: PC pins required

The ECQ-E2183KF meets all substitution criteria while offering improved specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

The ECQ-E2183KF is a direct functional substitute for the ECQ-M2183KZ. The substitute part exceeds the minimum requirements with a higher DC voltage rating (250V versus 200V) and extended operating temperature range (-40°C to 105°C versus -40°C to 85°C). The ECQ-E2183KF carries active product status and is ROHS3 compliant, making it suitable for new designs and ongoing production support. The metallized polyester dielectric in the substitute provides equivalent performance characteristics for general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can the ECQ-E2183KF be used as a direct replacement for the ECQ-M2183KZ?

A: Yes. Both parts share identical capacitance (0.018 µF), tolerance (±10%), and mounting configuration (through-hole radial with PC pins). The substitute meets or exceeds all electrical specifications of the original part.

Q: What are the physical differences between these parts?

A: The ECQ-E2183KF has different physical dimensions (0.406" L x 0.173" W, height 0.335") and reduced lead spacing (0.295" versus 0.492"). PCB layout verification is required before substitution to confirm mechanical compatibility.

Q: Why is the substitute rated for 250V DC instead of 200V DC?

A: The ECQ-E2183KF is designed with a higher voltage rating as a standard specification in the ECQ-E series. This higher rating does not affect circuit operation at 200V and provides additional design margin.

Q: Is the ECQ-E2183KF suitable for applications requiring the original operating temperature range?

A: Yes. The substitute operates across -40°C to 105°C, which encompasses the original part's -40°C to 85°C range and extends capability to higher temperatures.

Q: What compliance certifications apply to the substitute part?

A: The ECQ-E2183KF is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.
