Parameter Comparison

Engineering Selection Recommendations

The ECQ-UBAF102K is a direct parametric equivalent to the ECQ-UBAF102KA. Both components are manufactured by Panasonic Electronic Components within the ECQUB series and share identical electrical specifications, mechanical dimensions, and compliance certifications.

Both parts carry "Not For New Designs" status, indicating they are legacy components. Selection between these parts should be based on component availability and inventory requirements rather than technical differentiation, as all specified parameters are identical.

Both components maintain ROHS3 compliance and are suitable for applications requiring EMI and RFI suppression with X1 and Y2 safety ratings. The operating temperature range of -40°C to 110°C and 300V AC rating remain consistent across both parts.

Frequently Asked Questions (FAQ)

Q: Can the ECQ-UBAF102K be used as a direct replacement for the ECQ-UBAF102KA?

A: Yes. The ECQ-UBAF102K is a direct parametric equivalent. All electrical specifications (capacitance, tolerance, voltage rating, dielectric material), mechanical dimensions (lead spacing, physical size, height), and compliance certifications are identical between the two parts.

Q: Are there any differences in the radial lead spacing between these parts?

A: No. Both the ECQ-UBAF102KA and ECQ-UBAF102K feature identical lead spacing of 0.492" (12.50mm), ensuring compatible PCB footprints and through-hole mounting configurations.

Q: Do both parts meet the same compliance and safety standards?

A: Yes. Both components are ROHS3 compliant and carry identical X1 and Y2 safety ratings for EMI and RFI suppression applications. Operating temperature ranges are identical at -40°C to 110°C.

Q: What is the significance of the "Not For New Designs" status on both parts?

A: This status indicates that Panasonic has discontinued active development and support for these components. While both parts remain functionally equivalent and available in inventory, they are legacy products. For new design initiatives, consultation with component suppliers regarding current-generation alternatives may be appropriate.

Q: Are the physical dimensions identical between ECQ-UBAF102KA and ECQ-UBAF102K?

A: Yes. Both parts share identical physical dimensions of 0.602" L x 0.197" W (15.30mm x 5.00mm) with a maximum seated height of 0.472" (12.00mm), ensuring compatibility with existing PCB layouts and mechanical assemblies.
