ECW-F2275JB Film Capacitor Equivalent & Substitute Parts

Part Overview

The ECW-F2275JB is a 2.7 µF film capacitor manufactured by Panasonic Electronic Components, rated for 250V DC operation with polypropylene (PP) metallized dielectric. This component is designed for high-frequency and switching applications requiring radial through-hole mounting. The ECW-F2275JB is classified as obsolete, making identification of compatible substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECW-F2275JB is determined by the following critical parameters:

• Capacitance Value: Must be 2.7 µF (±5% tolerance acceptable)
• Voltage Rating - DC: Must be rated for minimum 250V DC
• Dielectric Material: Must be Polypropylene (PP), Metallized
• Mounting Type: Must be Through Hole
• Package / Case: Must be Radial configuration
• Termination: Must use PC Pins

The ECW-F2275JA meets all substitution criteria. While it features a smaller physical footprint and extended operating temperature range (-40°C ~ 105°C versus -25°C ~ 85°C), these differences represent improvements in performance envelope and do not restrict substitution. The ECW-F2275JA maintains identical electrical specifications for capacitance, tolerance, voltage rating, and dielectric material.

Parameter Comparison

Engineering Selection Recommendations

The ECW-F2275JA is a direct electrical substitute for the obsolete ECW-F2275JB. Both components share identical capacitance, tolerance, DC voltage rating, and dielectric material specifications. The ECW-F2275JA is currently in active production status with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment.

Physical dimensions differ between the two parts. The ECW-F2275JA is smaller in length, width, and height, with reduced lead spacing (0.787" versus 0.984"). PCB layout modifications may be required to accommodate the smaller footprint. The extended operating temperature range of the ECW-F2275JA (-40°C ~ 105°C) provides broader environmental performance compared to the ECW-F2275JB (-25°C ~ 85°C).

Frequently Asked Questions (FAQ)

Q: Can the ECW-F2275JA replace the ECW-F2275JB in existing designs?

A: Yes. Both components meet identical electrical requirements: 2.7 µF capacitance, ±5% tolerance, 250V DC rating, and polypropylene metallized dielectric. PCB layout verification is required due to differences in physical dimensions and lead spacing.

Q: What are the key differences between these parts?

A: The ECW-F2275JA features a smaller physical footprint (23.80mm x 11.40mm versus 28.00mm x 15.50mm), reduced lead spacing (20.00mm versus 25.00mm), and an extended operating temperature range (-40°C ~ 105°C versus -25°C ~ 85°C). The ECW-F2275JA is currently in active production with ROHS3 compliance.

Q: Are there any compatibility concerns with lead spacing differences?

A: Lead spacing differs between the two parts (0.787" for ECW-F2275JA versus 0.984" for ECW-F2275JB). PCB hole patterns must be verified for compatibility. If the original design uses the 0.984" spacing, the PCB layout must be modified to accommodate the 0.787" spacing of the substitute part.

Q: What is the inventory status of these parts?

A: The ECW-F2275JB (obsolete) has 852 pieces in stock. The ECW-F2275JA (active) has 1003 pieces in stock and represents the recommended long-term solution.

Q: Are both parts compliant with environmental regulations?

A: Both components are REACH Unaffected. The ECW-F2275JA carries ROHS3 compliance certification, while the ECW-F2275JB compliance status is not specified.
