Parameter Comparison

Engineering Selection Recommendations

The ECQ-UBAF102M is a direct parametric equivalent to the ECQ-UBAF102MA. 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 that neither component is recommended for new product development. For applications requiring this capacitor value and specification, evaluation of current-generation alternatives from Panasonic or other manufacturers should be conducted for new designs.

For legacy system maintenance and repair applications where the ECQ-UBAF102MA is specified, the ECQ-UBAF102M provides full functional and physical compatibility. The ECQ-UBAF102M maintains superior inventory availability (3343 pcs in stock versus 697 pcs for the ECQ-UBAF102MA), supporting continuity of supply for ongoing support requirements.

Both parts satisfy ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications in regulated markets.

Frequently Asked Questions (FAQ)

Q: Can the ECQ-UBAF102M be used as a direct replacement for the ECQ-UBAF102MA?

A: Yes. The ECQ-UBAF102M is a parametric equivalent with identical capacitance (1000 pF), tolerance (±20%), voltage rating (300V AC), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 110°C), and mechanical dimensions. Both components feature radial through-hole mounting with 0.492" (12.50mm) lead spacing and PC pin termination.

Q: Are there any differences in physical dimensions between these parts?

A: No. Both the ECQ-UBAF102MA and ECQ-UBAF102M share identical physical dimensions: 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 components.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the ECQ-UBAF102MA and ECQ-UBAF102M are ROHS3 compliant and REACH unaffected. Both carry X1, Y2 safety ratings for EMI and RFI suppression applications.

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

A: This status indicates that Panasonic has discontinued active development and support for these part numbers. While both components remain available for purchase and are suitable for maintenance and repair of existing systems, they should not be selected for new product development. Current-generation alternatives should be evaluated for new designs.

Q: Are the electrical characteristics identical between ECQ-UBAF102MA and ECQ-UBAF102M?

A: Yes. Both components are specified with 1000 pF capacitance, ±20% tolerance, 300V AC voltage rating, and -40°C ~ 110°C operating temperature range. The dielectric material is polypropylene metallized for both parts.

Q: What applications are these capacitors designed for?

A: Both the ECQ-UBAF102MA and ECQ-UBAF102M are specified for EMI and RFI suppression applications. The X1, Y2 safety ratings indicate suitability for line-to-neutral and line-to-ground filtering in AC power circuits.
