Substitute Part Grouping Explanation

Substitution of the ECQ-UBAF102VB is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must remain identical for a component to function as a direct substitute:

• Capacitance Value: 1000 pF (no tolerance deviation acceptable)
• Voltage Rating - AC: 300V minimum
• Dielectric Material: Polypropylene (PP), Metallized
• Tolerance: ±10%
• Operating Temperature Range: -40°C ~ 110°C minimum
• Mounting Type: Through Hole
• Package Configuration: Radial
• Lead Spacing: 0.591" (15.00mm)
• Termination Style: PC Pins
• Application Classification: EMI, RFI Suppression
• Safety Ratings: X1, Y2

The ECQ-UBAF102V5 meets all substitution criteria and is classified as a parametric equivalent. Both components share identical electrical specifications, physical dimensions, and safety certifications, enabling direct replacement in existing circuit designs.

Parameter Comparison

Engineering Selection Recommendations

The ECQ-UBAF102V5 is a direct parametric equivalent to the ECQ-UBAF102VB and functions as a complete substitute for all applications requiring 1000 pF film capacitors with 300V AC rating and polypropylene dielectric construction.

Both components maintain identical compliance certifications: ROHS3 compliance and REACH unaffected status. Both carry the same safety ratings (X1, Y2) for EMI and RFI suppression applications. The electrical performance, physical footprint, and thermal operating range are fully equivalent.

Selection between these two part numbers should be based on inventory availability and supply chain considerations. The ECQ-UBAF102V5 currently maintains higher inventory levels (2036 pcs) compared to the ECQ-UBAF102VB (623 pcs), which may influence procurement decisions for high-volume requirements or extended lead-time mitigation strategies.

Frequently Asked Questions (FAQ)
