Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECQ-UBAF472KA is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 4700 pF
• Tolerance: ±10%
• Voltage Rating - AC: 300V
• Dielectric Material: Polypropylene (PP), Metallized

Mechanical Parameters:

• Mounting Type: Through Hole
• Package / Case: Radial
• Lead Spacing: 0.492" (12.50mm)
• Termination: PC Pins

Environmental & Compliance Parameters:

• Operating Temperature Range: -40°C ~ 110°C
• Safety Ratings: X1, Y2
• RoHS Status: ROHS3 Compliant

Parts meeting all these criteria within the ECQUB series are classified as parametric equivalents and direct substitutes. The ECQ-UBAF472K variant is identified as a substitute based on identical electrical specifications, mechanical dimensions, and compliance certifications.
