Both parts belong to the Panasonic ECQUB series and share the base product number ECQ-UBAF332. The substitution is valid for direct replacement in applications requiring EMI and RFI suppression.

Parameter Comparison

Engineering Selection Recommendations

Both ECQ-UBAF332KA and ECQ-UBAF332K are Active products manufactured by Panasonic Electronic Components within the ECQUB series. Selection between these parts is based on availability and inventory status rather than technical differentiation, as all electrical and mechanical parameters are identical.

The ECQ-UBAF332KA maintains 900 pieces in current inventory stock. The ECQ-UBAF332K provides an alternative source with 1642 pieces available, offering increased availability for high-volume applications.

Both parts satisfy RoHS3 compliance requirements and REACH regulatory status. Both carry X1, Y2 safety ratings appropriate for EMI and RFI suppression in AC-rated applications. The 300V AC rating, polypropylene metallized dielectric, and -40°C to 110°C operating temperature range are maintained across both part numbers.

Frequently Asked Questions (FAQ)

Q: Can ECQ-UBAF332K be used as a direct replacement for ECQ-UBAF332KA?

A: Yes. Both parts are electrically and mechanically identical. All parameters including capacitance, voltage rating, dielectric material, physical dimensions, lead spacing, and safety ratings are equivalent. Direct substitution is valid for PCB assembly and circuit design applications.

Q: Are there differences in the physical package between these two parts?

A: No. Both parts share identical dimensions of 0.602" L x 0.197" W (15.30mm x 5.00mm) with a maximum seated height of 0.472" (12.00mm). Lead spacing is 0.492" (12.50mm) for both parts. PCB footprints and mounting requirements are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ECQ-UBAF332KA and ECQ-UBAF332K are RoHS3 compliant and REACH unaffected. Both carry X1, Y2 safety ratings for use in EMI and RFI suppression applications.

Q: What is the difference between these part numbers?

A: The part numbers differ only in their suffix designation (KA versus K). This distinction reflects internal Panasonic product coding and does not indicate functional or performance differences. Both parts belong to the ECQUB series and share the base product number ECQ-UBAF332.

Q: Are there any temperature or voltage derating considerations between these parts?

A: No. Both parts operate across the identical temperature range of -40°C to 110°C and maintain the same 300V AC voltage rating. Operating specifications are equivalent.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and supply chain requirements. Both parts maintain Active product status with equivalent long-term availability from Panasonic Electronic Components.
