• Voltage rating: Minimum 63V DC, 40V AC (equal or higher ratings acceptable)
• Dielectric type: Polyester metallized construction
• Mounting: Through-hole radial configuration
• Lead spacing: Compatible with 0.200" (5.08mm) pitch or equivalent mechanical fit
• Termination: PC pins for PCB insertion

The B32529C0334J000 from EPCOS - TDK Electronics meets all electrical and mechanical substitution criteria for the BF024D0334J.

Parameter Comparison

Engineering Selection Recommendations

The B32529C0334J000 is the direct electrical equivalent for the BF024D0334J. Selection of this substitute is based on the following factors:

• Electrical parameters are identical across capacitance, tolerance, and voltage ratings
• Operating temperature range of the substitute extends to 125°C, exceeding the original specification of 100°C
• The substitute maintains active product status, ensuring long-term availability and supply chain continuity
• ROHS3 compliance of the substitute aligns with current regulatory requirements, whereas the original part is non-compliant
• Lead spacing difference of 0.003" (0.08mm) is within typical PCB tolerance for radial through-hole components
• Both components feature identical termination and mounting configurations

Frequently Asked Questions (FAQ)

Q: Can the B32529C0334J000 be used as a direct replacement for the BF024D0334J?

A: Yes. Both components share identical electrical specifications: 0.33 µF capacitance, ±5% tolerance, and 63V DC / 40V AC voltage ratings. The radial through-hole package and PC pin termination are compatible. Lead spacing differs by 0.003" (0.08mm), which is within acceptable mechanical tolerance for PCB insertion.

Q: What is the primary reason for substitution?

A: The BF024D0334J is classified as obsolete. The B32529C0334J000 is an active product with confirmed inventory availability and ongoing manufacturer support.

Q: Are there compliance differences between these parts?

A: Yes. The BF024D0334J is RoHS non-compliant, while the B32529C0334J000 is ROHS3 compliant. Both are REACH unaffected and classified as EAR99 for export control purposes.

Q: Does the extended operating temperature range of the substitute affect compatibility?

A: No. The substitute's operating range of -55°C to 125°C encompasses the original specification of -55°C to 100°C. This provides additional thermal margin without affecting electrical performance within the original operating envelope.

Q: Are there any mechanical considerations for PCB layout?

A: Lead spacing differs by 0.003" (0.08mm) between the two parts. Standard PCB design tolerances for radial through-hole components accommodate this variation. Verify PCB hole spacing during layout review if transitioning between these parts.
