Substitute Part Grouping Explanation

Substitution eligibility for the ECQ-UBAF152KA is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for a component to function as a direct substitute:

• Capacitance value: 1500 pF
• Tolerance specification: ±10%
• Voltage rating (AC): 300V
• Dielectric material: Polypropylene (PP), Metallized
• Operating temperature range: -40°C ~ 110°C
• Mounting type: Through Hole
• Package configuration: Radial
• Lead spacing: 0.492" (12.50mm)
• Safety ratings: X1, Y2
• Compliance certifications: ROHS3 Compliant, REACH Unaffected

The ECQ-UBAF152K meets all substitution criteria and is classified as a parametric equivalent to the ECQ-UBAF152KA.

Parameter Comparison

Engineering Selection Recommendations

The ECQ-UBAF152K is a direct parametric equivalent to the ECQ-UBAF152KA and is suitable for applications requiring identical electrical performance and mechanical compatibility. Both components share the same ECQUB series designation and are manufactured by Panasonic Electronic Components.

The identical safety ratings (X1, Y2) confirm suitability for the same application categories, including EMI and RFI suppression circuits.

The ECQ-UBAF152K provides higher current inventory availability (1610 Pcs) compared to the ECQ-UBAF152KA (905 Pcs), which may influence procurement decisions for high-volume production or maintenance stock replenishment.

Frequently Asked Questions (FAQ)

Q: Can the ECQ-UBAF152K be used as a direct replacement for the ECQ-UBAF152KA in existing circuit designs?

A: Yes. The ECQ-UBAF152K is a parametric equivalent with identical capacitance, voltage rating, tolerance, dielectric material, operating temperature range, physical dimensions, lead spacing, and safety ratings. No circuit redesign or board layout modification is required.

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

A: No. Both components have identical dimensions: 0.602" L x 0.197" W (15.30mm x 5.00mm), maximum seated height of 0.472" (12.00mm), and lead spacing of 0.492" (12.50mm). They are mechanically interchangeable on printed circuit boards.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the ECQ-UBAF152KA and ECQ-UBAF152K are ROHS3 compliant and REACH unaffected, satisfying equivalent environmental and hazardous substance requirements.

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

A: This status indicates that Panasonic has discontinued active development and support for the ECQ-UBAF152KA. For new product development, the ECQ-UBAF152K should be selected as the active equivalent. Existing designs using the ECQ-UBAF152KA can continue operation without modification.

Q: Are the safety ratings identical between these components?

A: Yes. Both parts carry X1, Y2 safety ratings, confirming their suitability for the same EMI and RFI suppression applications.

Q: What is the difference between the part numbers ECQ-UBAF152KA and ECQ-UBAF152K?

A: The suffix "A" in ECQ-UBAF152KA and the absence of this suffix in ECQ-UBAF152K represent different packaging or distribution variants within the same ECQUB series. Both parts are electrically and mechanically identical and share the same base product number ECQ-UBAF152.
