Frequently Asked Questions (FAQ)

Q: Can ECQ-UBAF182V5 be used as a direct replacement for ECQ-UBAF182VB?

A: Yes. The ECQ-UBAF182V5 is a parametric equivalent with identical capacitance (1800 pF), voltage rating (300V AC), tolerance (±10%), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 110°C), mechanical dimensions, lead spacing, and safety ratings (X1, Y2). Both parts are through-hole radial capacitors with PC pin termination and identical physical footprints.

Q: Are there any differences in compliance or certifications between these parts?

A: No. Both ECQ-UBAF182VB and ECQ-UBAF182V5 are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8532.25.0020) classifications. Both parts maintain active production status.

Q: What is the difference between the part numbers ECQ-UBAF182VB and ECQ-UBAF182V5?

A: The part numbers differ only in the suffix designation (VB versus V5). Both parts share the same base product number ECQ-UBAF182 and are manufactured within the same ECQUB series. The suffix variation does not affect electrical performance, mechanical compatibility, or application suitability.

Q: Are these parts suitable for PCB assembly with standard through-hole mounting?

A: Yes. Both parts feature through-hole mounting with PC pin termination, 0.591" (15.00mm) lead spacing, and radial package configuration. The maximum seated height of 0.669" (17.00mm) accommodates standard PCB assembly processes.

Q: Can these capacitors be used in safety-critical applications?

A: Both parts carry X1, Y2 safety ratings, which designate them for use in EMI and RFI suppression applications. The specific application requirements and circuit design must be evaluated according to relevant safety standards and regulatory requirements.
