Substitute Part Grouping Explanation

Substitute parts for the ECQ-UBAF223KA are identified based on strict parametric equivalence within the ECQUB series. The substitution logic is based on the following critical parameters that must remain identical:

• Capacitance value: 0.022 µF
• Tolerance specification: ±10%
• Voltage rating (AC): 300V
• Dielectric material: Polypropylene (PP), Metallized
• Operating temperature range: -40°C ~ 110°C
• Mounting type: Through Hole
• Package configuration: Radial
• Lead spacing: 0.591" (15.00mm)
• Physical dimensions: 0.728" L x 0.236" W (18.50mm x 6.00mm)
• Height seated maximum: 0.433" (11.00mm)
• Termination type: PC Pins
• Application classification: EMI, RFI Suppression
• Ratings designation: X1
• Regulatory compliance: RoHS3 Compliant, REACH Unaffected

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection between these parts is based on availability and inventory status. The ECQ-UBAF223K maintains 1835 pieces in stock compared to 977 pieces for the ECQ-UBAF223KA. Both parts carry full RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. The identical parametric specifications ensure direct functional interchangeability in circuit applications requiring 0.022 µF, 300V AC rated film capacitors with polypropylene dielectric construction for EMI and RFI suppression.

Frequently Asked Questions (FAQ)

Q: Can ECQ-UBAF223K be used as a direct replacement for ECQ-UBAF223KA?

A: Yes. Both parts are parametric equivalents with identical capacitance (0.022 µF), voltage rating (300V AC), tolerance (±10%), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 110°C), physical dimensions, lead spacing, and termination type. They are functionally interchangeable in all applications.

Q: Are there any differences in regulatory compliance between these parts?

A: No. Both ECQ-UBAF223KA and ECQ-UBAF223K carry identical RoHS3 compliance and REACH unaffected status. They share the same ECCN (EAR99) and HTSUS (8532.25.0020) classifications.

Q: What is the significance of the different part number suffixes (KA vs K)?

A: The suffix variation indicates different packaging or distribution batches within the same base product number (ECQ-UBAF223). The electrical and mechanical specifications remain identical. Both are manufactured by Panasonic Electronic Components within the ECQUB series.

Q: Are these parts suitable for through-hole PCB assembly?

A: Yes. Both parts feature radial through-hole mounting with PC pin termination and 0.591" (15.00mm) lead spacing, compatible with standard through-hole PCB assembly processes.

Q: What applications are these capacitors designed for?

A: These capacitors are specified for EMI and RFI suppression applications with X1 rating classification, suitable for power line filtering and electromagnetic interference mitigation in electronic circuits.

Q: Can these parts operate across the full temperature range in all applications?

A: Both parts are rated for -40°C ~ 110°C operating temperature range. Application-specific thermal requirements should be evaluated based on circuit design and environmental conditions.
