ECQ-UBAF153VG Film Capacitor Equivalent & Substitute Parts

Part Overview

The ECQ-UBAF153VG is a 0.015 µF film capacitor manufactured by Panasonic Electronic Components, rated for 300V AC operation with polypropylene (PP) metallized dielectric construction. This radial through-hole component is designed for EMI and RFI suppression applications with an operating temperature range of -40°C to 110°C.

The ECQ-UBAF153VG carries a "Not For New Designs" product status designation. This status indicates the part is in mature or obsolescence phase. Identifying equivalent substitute parts ensures design continuity, maintains supply chain flexibility, and supports long-term production requirements for existing applications utilizing this capacitor specification.

Substitute Part Grouping Explanation

Substitution of the ECQ-UBAF153VG is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 0.015 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating - AC: 300V (exact match required)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)

Mechanical Parameters:

• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Size / Dimension: 0.728" L x 0.236" W / 18.50mm x 6.00mm (exact match required)
• Height - Seated (Max): 0.630" / 16.00mm (exact match required)
• Lead Spacing: 0.492" / 12.50mm (exact match required)
• Termination: PC Pins (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 match all parameters listed above to ensure functional and physical compatibility within existing circuit designs and PCB layouts.

Parameter Comparison
