Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECQ-UBAF122VB is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 1200 pF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - AC: 300V (exact match required)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)
• Safety Ratings: X1, Y2 (exact match required)

Mechanical Parameters:

• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Lead Spacing: 0.591" (15.00mm) (exact match required)

Environmental & Compliance Parameters:

• Operating Temperature Range: -40°C ~ 110°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

Substitute parts must satisfy all parameters listed above without deviation. Parts meeting these criteria are classified as parametric equivalents and direct functional replacements.

Parameter Comparison

Engineering Selection Recommendations

The ECQ-UBAF122V5 is a direct parametric equivalent to the ECQ-UBAF122VB. Both components are manufactured by Panasonic Electronic Components within the ECQUB series and share identical electrical, mechanical, and environmental specifications.
