Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PVC6018 is determined by the following critical electrical and mechanical parameters:

Electrical Parameters:

• Capacitance value of 0.18 µF (exact match required)
• Tolerance of ±10% or tighter
• Voltage rating equal to or exceeding 600V DC
• Polyester dielectric material
• Operating temperature range that accommodates the application requirements

Mechanical Parameters:

• Through-hole mounting type
• Radial package configuration
• PC pin termination

The ECQ-E6184KF meets these substitution criteria with a matching 0.18 µF capacitance, ±10% tolerance, and superior 630V DC voltage rating, while maintaining polyester dielectric construction and radial through-hole form factor.

Parameter Comparison

Engineering Selection Recommendations

The ECQ-E6184KF is an active, ROHS3-compliant substitute for the obsolete PVC6018. Both parts are ROHS3 Compliant and REACH Unaffected, supporting regulatory compliance requirements. The ECQ-E6184KF offers improved voltage margin with its 630V DC rating against the PVC6018's 600V specification, while maintaining identical capacitance and tolerance values.

Board-level integration requires evaluation of the reduced lead spacing (0.591" versus 1.343") and smaller physical dimensions of the ECQ-E6184KF, as these parameters directly affect PCB layout compatibility. The metallized polyester construction of the substitute provides equivalent electrical performance within the specified tolerance band.

Frequently Asked Questions (FAQ)

Q: Can the ECQ-E6184KF directly replace the PVC6018 in all applications? A: Electrical substitution is supported where capacitance (0.18 µF), tolerance (±10%), and voltage rating (≥600V DC) are the primary selection criteria. Physical dimensions and lead spacing differ and require PCB layout evaluation for mechanical compatibility.

Q: What is the significance of the metallized polyester dielectric in the ECQ-E6184KF? A: Both the PVC6018 and ECQ-E6184KF use polyester dielectric construction. The ECQ-E6184KF employs metallized polyester, which is functionally equivalent for the specified electrical parameters while providing self-healing properties under overvoltage conditions.

Q: Are there temperature range considerations for substitution? A: The PVC6018 operates from -55°C to 125°C, while the ECQ-E6184KF operates from -40°C to 105°C. Application-specific temperature requirements must be evaluated to confirm the ECQ-E6184KF operating range accommodates the intended use.

Q: Does the lead spacing difference affect electrical performance? A: Lead spacing is a mechanical parameter that affects PCB routing and component placement only. Electrical performance remains equivalent when lead spacing accommodates the design layout.

Q: Are both parts compliant with current environmental regulations? A: Both the PVC6018 and ECQ-E6184KF are ROHS3 Compliant and REACH Unaffected, supporting modern electronics manufacturing standards.
