ECQ-M2102KZ Equivalent & Substitute Parts

Part Overview

The ECQ-M2102KZ is a 1000 pF 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 newer alternatives, identifying equivalent substitute parts is essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECQ-M2102KZ is determined by the following critical parameters:

• Capacitance Value: Must be 1000 pF (exact match required)
• 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
• Package Compatibility: Radial case format with compatible lead spacing

The ECQ-E6102KF meets these substitution criteria with identical capacitance and tolerance values, higher voltage rating capability (630V DC), and compatible through-hole radial mounting. The metallized polyester dielectric provides enhanced performance characteristics while maintaining functional equivalence for 200V DC applications.

Parameter Comparison

Engineering Selection Recommendations

The ECQ-E6102KF serves as a direct functional substitute for the ECQ-M2102KZ in applications requiring 1000 pF capacitance at 200V DC or lower voltage levels. The substitute part provides superior voltage margin (630V DC rating versus 200V DC), extended operating temperature range (-40°C to 105°C versus -40°C to 85°C), and metallized polyester dielectric construction.

Both components are classified as obsolete products. The ECQ-E6102KF is ROHS3 compliant and REACH unaffected, providing regulatory alignment for new designs. Selection between these parts should be based on application voltage requirements, thermal operating conditions, and inventory availability. The higher voltage rating of the substitute part introduces no functional penalty for 200V DC applications and provides additional design margin.

Frequently Asked Questions (FAQ)

Q: Can the ECQ-E6102KF replace the ECQ-M2102KZ in a 200V DC circuit?

A: Yes. The ECQ-E6102KF has a 630V DC rating, which exceeds the 200V DC requirement of the original part. Capacitance value (1000 pF) and tolerance (±10%) are identical. Through-hole radial mounting and PC pin termination are compatible.

Q: What is the difference between polyester and metallized polyester dielectric?

A: Both are polyester-based dielectrics. The metallized polyester construction in the ECQ-E6102KF provides enhanced performance characteristics while maintaining the same capacitance and tolerance specifications required for substitution.

Q: Are there physical dimension differences between these parts?

A: The ECQ-M2102KZ specifies a lead spacing of 0.217" (5.50mm). The ECQ-E6102KF lead spacing is not specified in the provided data. Physical verification is necessary before PCB layout finalization to confirm mechanical compatibility.

Q: Why is the operating temperature range different?

A: The ECQ-E6102KF supports -40°C to 105°C operation, compared to -40°C to 85°C for the ECQ-M2102KZ. This extended range does not affect substitution for applications operating within the original part's temperature limits.

Q: Are both parts subject to the same export classifications?

A: Yes. Both components are classified under ECCN EAR99, indicating identical export control treatment.
