ECQ-UBAF683KA Equivalent & Substitute Parts

Part Overview

The ECQ-UBAF683KA is a 0.068 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 and carries an X1 rating classification. The part is Active in product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when electrical specifications, mechanical dimensions, and regulatory compliance remain identical across alternative part numbers within the same manufacturer series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECQ-UBAF683KA is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Capacitance value: 0.068 µF
• Tolerance: ±10%
• Voltage rating (AC): 300V
• Dielectric material: Polypropylene (PP), Metallized

Mechanical Specifications:

• Mounting type: Through Hole
• Package configuration: Radial
• Lead spacing: 0.591" (15.00mm)
• Physical dimensions: 0.728" L x 0.315" W (18.50mm x 8.00mm)
• Maximum seated height: 0.512" (13.00mm)
• Termination style: PC Pins

Regulatory & Compliance:

• RoHS3 Compliant
• REACH Unaffected
• X1 rating classification

Substitute parts must match all parameters listed above. Parts sharing the same base product number (ECQ-UBAF683) within the ECQUB series and maintaining identical electrical and mechanical specifications are classified as parametric equivalents.

Parameter Comparison

Engineering Selection Recommendations

Both the ECQ-UBAF683KA and ECQ-UBAF683K are Active products manufactured by Panasonic Electronic Components within the ECQUB series. Selection between these parts is based on availability and inventory status rather than technical differentiation.

ECQ-UBAF683KA is suitable for applications where current inventory allocation is available (725 Pcs in stock).

ECQ-UBAF683K is suitable for applications where higher inventory availability is required (2149 Pcs in stock) and serves as a direct parametric equivalent with identical electrical, mechanical, and compliance specifications.

Both parts maintain full RoHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in all applicable markets. The X1 rating classification applies uniformly across both part numbers for EMI and RFI suppression applications.

Frequently Asked Questions (FAQ)
