Key Parameters

Substitute Part Grouping Explanation

Substitution of the DSF050J334 is determined by the following critical parameters:

Electrical Compatibility:

• Capacitance value must equal 0.33 µF
• Tolerance must be ±5% or tighter
• Voltage rating must meet 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 ~ 85°C
• RoHS3 compliance required

The R82DC3330Z360J from KEMET satisfies all substitution criteria through equivalent capacitance, tolerance, dielectric composition, mechanical form factor, and lead spacing, while providing enhanced voltage rating and extended temperature range.

Parameter Comparison

Engineering Selection Recommendations

The R82DC3330Z360J is a direct substitute for the DSF050J334 based on the following factors:

Electrical Equivalence: Both components share identical capacitance (0.33 µF) and tolerance (±5%). The R82DC3330Z360J provides a higher DC voltage rating (63V versus 50V), which is compatible with applications designed for 50V operation.

Mechanical Compatibility: Lead spacing, termination style, and radial package configuration are identical, enabling direct board-level replacement without PCB modification.

Compliance & Availability: The R82DC3330Z360J holds active product status with ROHS3 compliance and AEC-Q200 automotive qualification. The substitute part is available in production quantities (9652 pcs in stock), whereas the original DSF050J334 is obsolete.

Temperature Performance: The R82DC3330Z360J operates across -55°C ~ 105°C, exceeding the original -40°C ~ 85°C range and providing enhanced thermal margin for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the R82DC3330Z360J replace the DSF050J334 in existing designs?

A: Yes. The R82DC3330Z360J meets all electrical and mechanical substitution criteria. Identical capacitance, tolerance, lead spacing, and radial through-hole configuration enable direct replacement. The higher voltage rating (63V) is compatible with 50V-rated circuit designs.

Q: What is the significance of the higher 63V rating on the substitute part?

A: The R82DC3330Z360J's 63V DC rating exceeds the original 50V specification. This provides additional voltage margin and does not create incompatibility; circuits designed for 50V operation function correctly with higher-rated components.

Q: Are there physical size differences between these parts?

A: Yes. The R82DC3330Z360J has slightly smaller dimensions (0.283" L x 0.138" W, 7.60mm height) compared to the DSF050J334 (0.287" L x 0.205" W, 8.00mm height). Lead spacing remains identical at 0.197" (5.00mm), ensuring PCB compatibility. Verify available board space for the substitute component.

Q: Does the R82DC3330Z360J meet automotive standards?

A: The R82DC3330Z360J carries AEC-Q200 qualification, indicating suitability for automotive applications. The original DSF050J334 does not specify automotive certification.

Q: Are both parts RoHS compliant?

A: Yes. Both the DSF050J334 and R82DC3330Z360J are ROHS3 compliant and REACH unaffected.
