Key Parameters

Substitute Part Grouping Explanation

Substitution of the DSF050J224 is determined by the following critical parameters:

Electrical Compatibility:

• Capacitance value must be 0.22 µF
• Tolerance must be ±5%
• Voltage rating must equal or exceed 50V DC
• Dielectric material must be polyester-based metallized construction

Mechanical Compatibility:

• Mounting type must be through-hole
• Package configuration must be radial
• Lead spacing must be 0.197" (5.00mm)
• Termination must be PC pins

Environmental & Compliance:

• Operating temperature range must encompass or exceed -40°C to 85°C
• RoHS3 compliance required

The substitute part R82EC3220Z370J from KEMET meets all electrical and mechanical compatibility criteria. This part maintains identical capacitance, tolerance, lead spacing, and termination specifications while providing enhanced voltage rating (100V DC) and extended operating temperature range (-55°C to 105°C).

Parameter Comparison

Engineering Selection Recommendations

The R82EC3220Z370J is a direct functional substitute for the DSF050J224 based on the following criteria:

Electrical Equivalence: Both parts share identical capacitance (0.22 µF) and tolerance (±5%). The R82EC3220Z370J provides a higher voltage rating (100V DC versus 50V DC), which is compatible with applications designed for the original 50V specification.

Mechanical Compatibility: Lead spacing, termination type, and radial package configuration are identical between both parts, ensuring direct PCB mounting compatibility without layout modifications.

Compliance & Availability: The R82EC3220Z370J maintains ROHS3 compliance and is classified as active product status with established supply chain availability (7129 pcs in stock), whereas the DSF050J224 is obsolete. The substitute part includes AEC-Q200 automotive qualification, providing additional reliability assurance.

Temperature Performance: The extended operating temperature range (-55°C to 105°C) of the R82EC3220Z370J encompasses the original specification range, ensuring thermal compatibility across all intended operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the R82EC3220Z370J replace the DSF050J224 in existing designs?

A: Yes. The R82EC3220Z370J is electrically and mechanically compatible. Both parts have identical capacitance (0.22 µF), tolerance (±5%), lead spacing (5.00mm), and radial through-hole configuration. The substitute part's higher voltage rating (100V versus 50V) and extended temperature range provide enhanced performance margins.

Q: Are there physical size differences between these parts?

A: Minor dimensional variations exist. The DSF050J224 measures 0.287" L x 0.189" W with 0.256" seated height. The R82EC3220Z370J measures 0.283" L x 0.138" W with 0.299" seated height. Lead spacing remains identical at 0.197" (5.00mm), ensuring PCB compatibility. Verify clearance in confined mounting areas.

Q: What is the difference between polyester and PET dielectric materials?

A: Both materials are polyester-based. Polyethylene Terephthalate (PET) is a specific polyester formulation. The R82EC3220Z370J uses PET with metallized-stacked construction, providing equivalent electrical performance to the original polyester metallized-stacked design of the DSF050J224.

Q: Why does the substitute part have a higher voltage rating?

A: The R82EC3220Z370J is rated for 100V DC, exceeding the original 50V specification. This higher rating does not affect circuit operation at 50V or lower. Higher voltage-rated capacitors typically offer improved reliability margins and extended operational life in the specified voltage range.

Q: Is the R82EC3220Z370J suitable for automotive applications?

A: Yes. The R82EC3220Z370J carries AEC-Q200 automotive qualification. The original DSF050J224 was specified for general-purpose applications. The substitute part's automotive qualification provides additional reliability assurance if required by updated design standards.

Q: What is the lead spacing and is it compatible with standard PCB layouts?

A: Both parts have 0.197" (5.00mm) lead spacing, which is a standard radial capacitor pitch. This spacing is compatible with conventional through-hole PCB designs without modification.
