Substitute Part Grouping Explanation

Substitution of the ECQ-UBAF472VB is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part ECQ-UBAF472V5 is classified as a parametric equivalent because it maintains identical specifications in the following key areas:

• Capacitance value: 4700 pF
• Tolerance: ±10%
• Voltage rating: 300V AC
• Dielectric material: Polypropylene (PP), Metallized
• Operating temperature range: -40°C ~ 110°C
• Mounting configuration: Through Hole, Radial
• Physical dimensions: 0.602" L x 0.197" W (15.30mm x 5.00mm)
• Lead spacing: 0.591" (15.00mm)
• Height seated: 0.669" (17.00mm)
• Termination type: PC Pins
• Safety ratings: X1, Y2
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

Both parts belong to the ECQUB series and share the base product number ECQ-UBAF472, differing only in packaging designation suffix.

Parameter Comparison

Engineering Selection Recommendations

Both the ECQ-UBAF472VB and ECQ-UBAF472V5 are active production parts manufactured by Panasonic Electronic Components and are fully compliant with ROHS3 and REACH regulations. Selection between these parts is based on availability and inventory status rather than electrical or mechanical performance differences.

The ECQ-UBAF472VB carries 818 units in current stock inventory. The ECQ-UBAF472V5 substitute carries 2582 units in stock, providing significantly greater availability for high-volume procurement or extended lead time mitigation.

Both parts maintain identical electrical performance in EMI and RFI suppression applications, identical mechanical fit for through-hole PCB assembly, and identical safety certifications for X1, Y2 rated applications. Direct substitution is electrically and mechanically valid without circuit redesign or PCB layout modification.
