ECQ-UBAF392VB Equivalent & Substitute Parts

Part Overview

The ECQ-UBAF392VB is a 3900 pF 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 X1, Y2 safety ratings. The part is currently in active production status with ROHS3 compliance and REACH unaffected designation. Substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or equivalent performance specifications across the same product family.

Substitute Part Grouping Explanation

Substitution eligibility for the ECQ-UBAF392VB is determined by strict equivalence across the following critical parameters: capacitance value (3900 pF), tolerance specification (±10%), AC voltage rating (300V), dielectric material composition (polypropylene metallized), operating temperature range (-40°C ~ 110°C), mounting configuration (through-hole radial), lead spacing (15.00mm), and safety certifications (X1, Y2). Parts meeting all these criteria are classified as parametric equivalents within the ECQUB series. The ECQ-UBAF392V5 satisfies all substitution criteria and is therefore listed as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both ECQ-UBAF392VB and ECQ-UBAF392V5 are active production components from Panasonic Electronic Components with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain requirements rather than performance differentiation. Both parts carry ROHS3 compliance certification and REACH unaffected status, meeting current regulatory requirements for industrial and commercial applications. The ECQ-UBAF392V5 variant currently maintains higher inventory levels (1995 pcs) compared to the ECQ-UBAF392VB (990 pcs), making it suitable for high-volume procurement scenarios. Either part is functionally interchangeable in circuit designs requiring 3900 pF capacitance at 300V AC with EMI/RFI suppression characteristics.

Frequently Asked Questions (FAQ)

Q: Are ECQ-UBAF392VB and ECQ-UBAF392V5 electrically identical?

A: Yes. Both parts share identical capacitance (3900 pF), tolerance (±10%), voltage rating (300V AC), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 110°C), and safety certifications (X1, Y2).

Q: Can these parts be used interchangeably on the same PCB?
