ECW-F2225JB Equivalent & Substitute Parts
Part Overview
The ECW-F2225JB is a 2.2 µF film capacitor rated for 250V DC, manufactured by Panasonic Electronic Components. This radial through-hole component uses polypropylene (PP) metallized dielectric technology and is designed for high-frequency and switching applications. The part is currently obsolete, making equivalent substitutes necessary for ongoing design support and production requirements.

Key Parameters
| Parameter | Value |
|---|---|
| Capacitance | 2.2 µF |
| Tolerance | ±5% |
| Voltage Rating - DC | 250V |
| Dielectric Material | Polypropylene (PP), Metallized |
| Mounting Type | Through Hole |
| Package / Case | Radial |
| Termination | PC Pins |
| Operating Temperature Range | -25°C ~ 85°C |
Substitute Part Grouping Explanation
Substitution eligibility for the ECW-F2225JB is determined by the following critical parameters:
- Capacitance value: 2.2 µF (exact match required)
- Tolerance: ±5% (exact match required)
- Voltage Rating - DC: 250V (minimum requirement)
- Dielectric Material: Polypropylene (PP), Metallized (exact match required)
- Mounting Type: Through Hole (exact match required)
- Package / Case: Radial (exact match required)
- Termination: PC Pins (exact match required)
The ECW-F2225JA qualifies as a direct substitute based on these parameters. Both parts share identical capacitance, tolerance, DC voltage rating, dielectric material, mounting type, package configuration, and termination style. Variations in physical dimensions, lead spacing, and operating temperature range do not preclude substitution when the electrical and mechanical interface requirements are met.

Engineering Selection Recommendations
The ECW-F2225JA is the qualified substitute for the obsolete ECW-F2225JB. Both parts meet identical electrical specifications for capacitance, tolerance, and DC voltage rating. The ECW-F2225JA offers extended operating temperature range (-40°C ~ 105°C versus -25°C ~ 85°C) and is currently in active production status with ROHS3 compliance certification.
Physical dimensions and lead spacing differ between the two parts. The ECW-F2225JA is smaller (18.80mm x 12.60mm with 15.00mm lead spacing) compared to the ECW-F2225JB (28.00mm x 14.00mm with 25.00mm lead spacing). PCB layout modifications are required to accommodate the different lead spacing and component footprint of the substitute part.
Frequently Asked Questions (FAQ)
Q: Can ECW-F2225JA be used as a direct replacement for ECW-F2225JB without circuit modifications?
A: The electrical specifications are identical, but PCB layout changes are necessary due to different lead spacing (15.00mm versus 25.00mm) and component dimensions. The substitute part requires a modified footprint design.
Q: What is the difference in operating temperature range between these parts?
A: The ECW-F2225JB operates from -25°C to 85°C, while the ECW-F2225JA operates from -40°C to 105°C. The substitute part provides a wider temperature operating window.
Q: Are both parts compliant with current environmental regulations?
A: The ECW-F2225JA is ROHS3 compliant. Compliance information for the ECW-F2225JB is not provided in the technical data.
Q: Why is the ECW-F2225JB obsolete?
A: Product status reflects manufacturer discontinuation. The ECW-F2225JA remains in active production and serves as the current equivalent offering.
Q: Do the different physical dimensions affect electrical performance?
A: No. Electrical performance is determined by capacitance, tolerance, voltage rating, and dielectric material—all of which are identical between the two parts. Physical dimensions affect only PCB layout and mechanical fit.
