ECW-FD2W105JC Equivalent & Substitute Parts

Part Overview

The ECW-FD2W105JC is a 1 µF film capacitor manufactured by Panasonic Electronic Components, rated for 450V DC operation with polypropylene (PP) metallized dielectric construction. This radial through-hole component is designed for EMI/RFI suppression, high-frequency switching, and high pulse/DV/DT applications. The part maintains Active product status with 1393 units in current inventory stock. Substitute parts are identified to provide alternative sourcing options when the primary part number becomes unavailable or when inventory constraints require component alternatives that maintain equivalent electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the ECW-FD2W105JC is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 1 µF
• Tolerance: ±5%
• Voltage Rating - DC: 450V
• Dielectric Material: Polypropylene (PP), Metallized
• Operating Temperature Range: -40°C ~ 110°C
• Mounting Type: Through Hole
• Package / Case: Radial
• Physical Dimensions: 0.689" L x 0.307" W (17.50mm x 7.80mm)
• Height - Seated (Max): 0.630" (16.00mm)
• Lead Spacing: 0.295" (7.50mm)
• Termination: PC Pins
• Series: ECW-F(D)

The substitute part ECW-FD2W105JB meets all mandatory matching parameters and is therefore classified as a parametric equivalent. Both parts share identical capacitance, tolerance, DC voltage rating, dielectric composition, temperature range, mechanical form factor, and termination specifications. The presence of an AC voltage rating specification in the substitute part does not alter its DC circuit equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the ECW-FD2W105JC and ECW-FD2W105JB maintain Active product status with full ROHS3 compliance and REACH Unaffected classification, confirming ongoing manufacturer support and regulatory compliance for both components. Selection between these parts should be based on inventory availability and supply chain requirements, as both parts satisfy identical electrical and mechanical specifications for DC circuit applications.

The ECW-FD2W105JB currently maintains higher inventory levels (1810 units) compared to the ECW-FD2W105JC (1393 units), which may influence procurement decisions when component availability is a consideration. Both parts are manufactured by Panasonic Electronic Components within the ECW-F(D) series and are suitable for direct substitution in through-hole PCB applications requiring 1 µF capacitance at 450V DC with polypropylene dielectric construction.

Frequently Asked Questions (FAQ)

Q: Can ECW-FD2W105JB be used as a direct replacement for ECW-FD2W105JC?

A: Yes. Both parts are parametric equivalents sharing identical capacitance (1 µF), tolerance (±5%), DC voltage rating (450V), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 110°C), and physical dimensions (0.689" L x 0.307" W, 7.50mm lead spacing). The parts are mechanically and electrically interchangeable in through-hole PCB applications.

Q: What is the significance of the AC voltage rating difference between these parts?

A: The ECW-FD2W105JB specifies an 84V AC rating while the ECW-FD2W105JC does not include an AC specification. For DC-only circuit applications, this difference is not relevant to component selection. Both parts maintain identical 450V DC ratings and are suitable for DC circuit operation.

Q: Are both parts suitable for EMI/RFI suppression applications?

A: Yes. Both ECW-FD2W105JC and ECW-FD2W105JB are specified for EMI/RFI suppression, high-frequency switching, and high pulse/DV/DT applications. The polypropylene metallized dielectric construction and 450V DC rating support these application requirements in both parts.

Q: Do these parts require any special handling or storage considerations?

A: Both parts carry ROHS3 compliance and REACH Unaffected status. Moisture Sensitivity Level (MSL) is Not Applicable for both components. Standard through-hole component handling and storage procedures apply.

Q: What is the lead spacing for PCB layout purposes?

A: Both parts feature 0.295" (7.50mm) lead spacing, enabling direct PCB footprint compatibility. The radial package configuration with PC pin termination supports standard through-hole soldering processes.

Q: Are there any differences in the base product number between these parts?

A: Both parts share the same base product number ECW-FD, confirming they belong to the same product family within the Panasonic ECW-F(D) series. The suffix variations (JC versus JB) indicate minor specification differences while maintaining core electrical equivalence.
