Substitute Part Grouping Explanation

Substitution eligibility for the ECQ-UBAF472MC is determined by strict parametric matching across the following critical criteria:

• Capacitance value: 4700 pF (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)
• Ratings: X1, Y2 (exact match required)

The ECQ-UBAF472M qualifies as a parametric equivalent based on complete alignment with all specified electrical and mechanical parameters. Both parts share the same base product number (ECQ-UBAF472) and series designation (ECQUB), confirming their functional interchangeability within the defined application scope.

Parameter Comparison

Engineering Selection Recommendations

Both ECQ-UBAF472MC and ECQ-UBAF472M are active production components from Panasonic Electronic Components with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability and supply chain requirements. The ECQ-UBAF472M currently maintains higher stock levels (1259 units versus 783 units), which may support extended lead time requirements or volume procurement scenarios. Both parts comply with applicable regulatory standards including RoHS3 compliance and REACH unaffected status for the ECQ-UBAF472M variant. ECCN classification (EAR99) applies to both parts.

Frequently Asked Questions (FAQ)
