Frequently Asked Questions (FAQ)

Q: Are ECQ-UBAF272VB and ECQ-UBAF272V5 directly interchangeable?

A: Yes. Both parts are identical across all electrical parameters (capacitance, voltage rating, tolerance, dielectric material, operating temperature), mechanical parameters (package type, lead spacing, dimensions, termination), and compliance certifications (RoHS3, REACH status). They are part of the same ECQUB series with the same base product number ECQ-UBAF272.

Q: What is the difference between ECQ-UBAF272VB and ECQ-UBAF272V5?

A: The parts differ only in their specific part number suffix (VB versus V5). All functional, electrical, mechanical, and compliance specifications are identical. The suffix variation reflects internal Panasonic manufacturing or packaging designations that do not affect performance or compatibility.

Q: Can these parts be used in PCB designs without modification?

A: Yes. Both parts use identical radial through-hole mounting with 0.591" (15.00mm) lead spacing and PC pin termination. PCB footprints designed for either part number accommodate both without modification.

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

A: Yes. Both ECQ-UBAF272VB and ECQ-UBAF272V5 are specified for EMI and RFI suppression applications and carry X1, Y2 safety ratings appropriate for such use.

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

A: Both parts operate across -40°C to 110°C, providing consistent thermal performance across standard industrial and commercial temperature ranges.

Q: Are these parts RoHS compliant?

A: Yes. Both ECQ-UBAF272VB and ECQ-UBAF272V5 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.
