Key Parameters

Substitute Part Grouping Explanation

The ECQ-E4183JF qualifies as a direct substitute based on the following criteria:

Matching Parameters:

• Capacitance: 0.018 µF (identical)
• Tolerance: ±5% (identical)
• Dielectric Material: Polyester, Metallized (identical)
• Operating Temperature Range: -40°C ~ 105°C (identical)
• Mounting Type: Through Hole (identical)
• Package / Case: Radial (identical)
• Lead Spacing: 0.295" (7.50mm) (identical)
• Termination: PC Pins (identical)
• Series: ECQ-E(F) (identical)
• Manufacturer: Panasonic Electronic Components (identical)

Voltage Rating Difference: The ECQ-E4183JF operates at 400V DC (versus 250V DC for the main part), providing enhanced voltage capability within the same physical footprint and electrical specifications. This substitution is valid for applications where the original 250V rating is sufficient, as the higher-rated component maintains all other electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both ECQ-E2183JFW and ECQ-E4183JF maintain Active product status with identical RoHS3 compliance and REACH unaffected certifications, ensuring regulatory alignment for current and future applications. The ECQ-E4183JF provides higher voltage margin (400V DC versus 250V DC) while maintaining identical capacitance, tolerance, temperature range, and lead spacing specifications. The reduced seated height of the ECQ-E4183JF (8.50mm versus 12.50mm) may offer PCB layout advantages in space-constrained designs. Component selection should be based on circuit voltage requirements and available board clearance.

Frequently Asked Questions (FAQ)

Q: Can ECQ-E4183JF replace ECQ-E2183JFW in all applications?

A: Yes, provided the circuit voltage does not exceed 250V DC. The ECQ-E4183JF's 400V DC rating is compatible with any application designed for 250V operation. All other electrical parameters (capacitance, tolerance, temperature range, dielectric material) are identical.

Q: What is the physical difference between these parts?

A: Both components share identical length (0.406"), width (0.173"), and lead spacing (0.295"). The primary physical difference is seated height: ECQ-E2183JFW measures 0.492" (12.50mm) maximum, while ECQ-E4183JF measures 0.335" (8.50mm) maximum. This difference may affect PCB layout compatibility.
