Substitute Part Grouping Explanation

Substitution eligibility for the ECQ-UBAF104VG is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 0.1 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating - AC: 300V (exact match required)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)
• Operating Temperature Range: -40°C ~ 110°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Configuration: Radial (exact match required)
• Lead Spacing: 0.492" (12.50mm) (exact match required)
• Safety Rating: X1 (exact match required)

The ECQ-UBAF104V2 meets all substitution criteria as a parametric equivalent. Both parts share identical electrical specifications, physical dimensions, thermal characteristics, and application suitability. Substitution between these parts is valid for direct component replacement in existing designs and repair applications.
