ECQ-UBAF473VG Film Capacitor Equivalent & Substitute Parts

Part Overview

The ECQ-UBAF473VG is a 0.047 µF film capacitor manufactured by Panasonic Electronic Components, designed for EMI and RFI suppression applications. This radial polypropylene metallized film capacitor operates at 300V AC with a ±20% tolerance and is rated for X1 applications. The part is Active in product status and ROHS3 compliant. Substitute parts are identified when inventory constraints, lead time requirements, or procurement preferences necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the ECQ-UBAF473VG and ECQ-UBAF473V2 are Active products from Panasonic Electronic Components within the ECQUB series. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement. The parts are electrically and mechanically identical across all specified parameters, including capacitance, voltage rating, dielectric composition, temperature range, physical dimensions, and lead configuration. Selection between these parts is based on inventory availability and procurement lead time rather than technical performance differences. The ECQ-UBAF473V2 variant currently maintains higher inventory levels (3686 Pcs) compared to the ECQ-UBAF473VG (692 Pcs), which may influence sourcing decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can ECQ-UBAF473V2 be used as a direct replacement for ECQ-UBAF473VG?

A: Yes. The ECQ-UBAF473V2 is a parametric equivalent with identical electrical specifications (0.047 µF, ±20%, 300V AC), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 110°C), and mechanical configuration (radial through-hole, 12.50mm lead spacing). Both parts are ROHS3 compliant and rated for X1 applications in EMI/RFI suppression circuits.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical dimensions: 0.728" L x 0.276" W (18.50mm x 7.00mm) with a maximum seated height of 0.669" (17.00mm) and lead spacing of 0.492" (12.50mm). PCB layout and mounting hole spacing require no modification when substituting between these parts.

Q: What is the difference between ECQ-UBAF473VG and ECQ-UBAF473V2?

A: Both parts are from the same ECQUB series and share identical electrical and mechanical specifications. The designation difference (VG vs. V2) reflects internal Panasonic product line variants. No functional or performance differences exist between the two parts.

Q: Are both parts suitable for EMI and RFI suppression applications?

A: Yes. Both the ECQ-UBAF473VG and ECQ-UBAF473V2 are rated for EMI and RFI suppression with X1 application classification. The polypropylene metallized dielectric and 300V AC rating support these filtering applications.

Q: What is the operating temperature range for these capacitors?

A: Both parts operate across -40°C to 110°C. This temperature range applies to all electrical and mechanical specifications throughout the operating life of the component.

Q: Are these parts RoHS and REACH compliant?

A: Yes. Both ECQ-UBAF473VG and ECQ-UBAF473V2 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component procurement in regulated markets.
