ECQ-UBAF474MA Film Capacitor Equivalent & Substitute Parts

Part Overview

The ECQ-UBAF474MA is a 0.47 µF film capacitor manufactured by Panasonic Electronic Components, designed for EMI and RFI suppression applications. This radial through-hole capacitor operates at 300V AC with a polypropylene metallized dielectric and maintains an operating temperature range of -40°C to 110°C. The part is currently in active production status with ROHS3 compliance and REACH unaffected classification. Substitute parts are identified when identical electrical specifications, mechanical dimensions, and compliance certifications are maintained across alternative part numbers within the same manufacturer series.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ECQ-UBAF474MA are identified based on strict parametric equivalence within the Panasonic ECQUB series. The substitution criteria are limited to the following parameters:

• Capacitance value: 0.47 µF
• Tolerance: ±20%
• Voltage rating (AC): 300V
• Dielectric type: Polypropylene (PP), Metallized
• Operating temperature range: -40°C ~ 110°C
• Mounting configuration: Through Hole Radial
• Lead spacing: 0.886" (22.50mm)
• Physical dimensions: 1.024" L x 0.551" W (26.00mm x 14.00mm)
• Height seated maximum: 0.846" (21.50mm)
• Termination type: PC Pins
• Compliance certifications: ROHS3 Compliant, REACH Unaffected

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. No electrical performance degradation or circuit redesign is required when substituting between equivalent parts.

Parameter Comparison

Engineering Selection Recommendations

Both ECQ-UBAF474MA and ECQ-UBAF474M are active production parts from Panasonic Electronic Components with identical electrical and mechanical specifications. Selection between these parts is based on availability and inventory status rather than technical performance differences.

ECQ-UBAF474MA carries 868 pieces in current inventory stock. ECQ-UBAF474M carries 1254 pieces in current inventory stock, providing higher availability for procurement.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications. The identical capacitance value (0.47 µF), voltage rating (300V AC), tolerance (±20%), and physical dimensions ensure direct interchangeability in PCB layouts and circuit designs without modification.

Frequently Asked Questions (FAQ)

Q: Can ECQ-UBAF474M be used as a direct replacement for ECQ-UBAF474MA?

A: Yes. Both parts are parametric equivalents with identical capacitance (0.47 µF), voltage rating (300V AC), tolerance (±20%), dielectric material (polypropylene metallized), operating temperature range (-40°C to 110°C), physical dimensions, lead spacing (22.50mm), and termination type (PC pins).
