Substitute Part Grouping Explanation

Substitution of the ECQ-UBAF683MA is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part ECQ-UBAF683M maintains identical specifications in the following areas:

  • Capacitance value: 0.068 µF
  • Tolerance: ±20%
  • Voltage rating: 300V AC
  • Dielectric composition: Polypropylene (PP), Metallized
  • Operating temperature range: -40°C ~ 110°C
  • Mounting configuration: Through Hole, Radial
  • Physical dimensions: 0.728" L x 0.315" W (18.50mm x 8.00mm)
  • Lead spacing: 0.591" (15.00mm)
  • Termination type: PC Pins
  • Series classification: ECQUB
  • Ratings designation: X1

Both parts belong to the same ECQUB series and share identical base product number ECQ-UBAF683, with substitution occurring only at the packaging designation level. This ensures complete functional and mechanical interchangeability in circuit designs requiring 0.068 µF film capacitors at 300V AC for EMI/RFI suppression.

Engineering Selection Recommendations

Both ECQ-UBAF683MA and ECQ-UBAF683M are active production parts from Panasonic Electronic Components with identical compliance certifications. Selection between these parts is based on packaging designation and inventory availability rather than electrical or mechanical performance differences.

The ECQ-UBAF683MA is available with 831 pieces in stock, while the ECQ-UBAF683M offers higher inventory availability at 1668 pieces. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory conformance for applications requiring 0.068 µF film capacitors at 300V AC.

For applications requiring immediate availability or higher stock quantities, the ECQ-UBAF683M is the preferred selection. For applications with existing design documentation specifying the ECQ-UBAF683MA designation, direct substitution with ECQ-UBAF683M is electrically and mechanically valid without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can ECQ-UBAF683M be used as a direct replacement for ECQ-UBAF683MA?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including capacitance, voltage rating, tolerance, dielectric material, operating temperature range, physical dimensions, and lead spacing. Direct substitution is valid for circuit applications.

Q: What is the difference between ECQ-UBAF683MA and ECQ-UBAF683M?

A: The parts differ only in packaging designation. Both share the same base product number ECQ-UBAF683 and are part of the ECQUB series. The designation suffix indicates packaging configuration, not electrical performance.

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

A: Yes. Both ECQ-UBAF683MA and ECQ-UBAF683M are rated for EMI and RFI suppression with X1 ratings and identical electrical specifications.

Q: What is the lead spacing for these radial capacitors?

A: The lead spacing is 0.591 inches (15.00mm) for both parts, ensuring compatibility with standard through-hole PCB layouts.

Q: Do these parts require moisture sensitivity handling?

A: No. Moisture Sensitivity Level (MSL) is not applicable to these film capacitors, eliminating special storage and handling requirements.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both ECQ-UBAF683MA and ECQ-UBAF683M are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for electronic component applications.

Q: What is the operating temperature range for these capacitors?

A: Both parts operate across -40°C to 110°C, providing performance stability across industrial and commercial temperature environments.
