ECW-F6183JLB Film Capacitor Equivalent & Substitute Parts

Part Overview

The ECW-F6183JLB is a 0.018 µF film capacitor rated for 630V DC, manufactured by Panasonic Electronic Components. This radial through-hole component uses polypropylene (PP) metallized dielectric technology and operates across a temperature range of -40°C to 105°C. The part is currently active in production with 823 units in stock. Film capacitors of this specification are essential in high-frequency switching applications, EMI/RFI suppression circuits, and high-pulse environments where reliability and frequency response are critical design parameters.

Key Parameters

Substitute Part Grouping Explanation

The ECW-FD2J183JB qualifies as a direct substitute for the ECW-F6183JLB based on the following critical parameters:

Matching Parameters (Substitution Basis):

• Capacitance: 0.018 µF (identical)
• Voltage Rating (DC): 630V (identical)
• Tolerance: ±5% (identical)
• Dielectric Material: Polypropylene (PP), Metallized (identical)
• Mounting Type: Through Hole (identical)
• Package Type: Radial (identical)
• Lead Spacing: 0.295" (7.50mm) (identical)
• Operating Temperature Range: -40°C to 105°C (identical)
• Termination: PC Pins (identical)
• RoHS Status: ROHS3 Compliant (identical)

Mechanical Variations (Non-Critical): The substitute part exhibits minor dimensional differences in length (0.496" vs 0.492") and height (0.351" vs 0.555"), which reflect design optimization within the same product family but do not affect electrical performance or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the ECW-F6183JLB and ECW-FD2J183JB are active production components manufactured by Panasonic Electronic Components and carry ROHS3 compliance certification. The electrical specifications are identical across all critical parameters: capacitance, voltage rating, tolerance, dielectric material, and operating temperature range. The substitute part (ECW-FD2J183JB) offers higher inventory availability (1729 units versus 823 units) and a more compact form factor with reduced seated height (0.351" versus 0.555"), which may provide advantages in space-constrained PCB layouts. Both parts are suitable for high-frequency switching, EMI/RFI suppression, and high-pulse applications. Selection between these parts should be based on PCB layout constraints and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can ECW-FD2J183JB be used as a direct replacement for ECW-F6183JLB in existing designs?

A: Yes. The substitute part maintains identical electrical specifications across all critical parameters: 0.018 µF capacitance, 630V DC rating, ±5% tolerance, polypropylene metallized dielectric, and identical lead spacing (0.295" / 7.50mm). Both parts are through-hole radial components with PC pin termination. The primary difference is physical form factor, with the substitute offering a more compact height profile.

Q: What are the dimensional differences between these parts?

A: The ECW-FD2J183JB is slightly longer (0.496" vs 0.492") and narrower (0.232" vs 0.244"), with significantly reduced seated height (0.351" vs 0.555"). These variations reflect design optimization within the ECW-F product family but do not affect electrical performance or circuit compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both ECW-F6183JLB and ECW-FD2J183JB carry ROHS3 compliance certification and are manufactured by Panasonic Electronic Components.

Q: Which part should be selected for new designs?

A: Selection should be based on PCB layout requirements and supply availability. The ECW-FD2J183JB offers superior inventory availability and a more compact form factor suitable for space-constrained applications. Both parts are active production components with identical electrical performance.

Q: Do these parts have different application suitability?

A: Both parts are rated for identical applications: high-frequency switching, EMI/RFI suppression, and high-pulse environments. The operating temperature range (-40°C to 105°C) is identical for both components.
