Parameter Comparison

Engineering Selection Recommendations

The BFC237341475 (Vishay Beyschlag/Draloric/BC Components) is a qualified substitute for the DMM2W4P7K-F based on the following engineering criteria:

Electrical Compatibility: Both parts share identical capacitance (4.7 µF), tolerance (±10%), and voltage ratings (250V DC / 160V AC). The polyester metallized dielectric technology is identical, ensuring equivalent electrical performance in circuit applications.

Mechanical Compatibility: Lead spacing matches at 1.083" (27.50mm), enabling direct PCB footprint compatibility. Both components use radial through-hole mounting with PC pin termination. Minor dimensional variations (width 1mm difference, height 2mm difference) do not affect circuit board assembly or electrical function.

Compliance Status: Both parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes. Moisture Sensitivity Level 1 (Unlimited) is identical for both parts.

Temperature Rating Consideration: The DMM2W4P7K-F operates to 125°C, while the BFC237341475 operates to 105°C. For applications operating above 105°C, the CDE part is required. For applications operating at or below 105°C, both parts are functionally equivalent.

Product Status: Both parts are Active in product status with current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can BFC237341475 be used as a direct replacement for DMM2W4P7K-F in all applications?

A: Yes, for applications operating at or below 105°C. The BFC237341475 has a maximum operating temperature of 105°C, while the DMM2W4P7K-F is rated to 125°C. If your circuit operates above 105°C, the DMM2W4P7K-F must be used.

Q: Are the physical dimensions compatible with existing PCB layouts?

A: Yes. The lead spacing is identical at 1.083" (27.50mm), which determines PCB hole pattern compatibility. Minor differences in body width (1mm) and height (2mm) do not affect circuit board assembly. Both components fit standard radial capacitor footprints designed for 27.50mm lead spacing.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the DMM2W4P7K-F and BFC237341475 are ROHS3 Compliant, REACH Unaffected, and classified as EAR99. Both have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements.

Q: What is the key difference between these two parts?

A: The primary difference is the maximum operating temperature. The DMM2W4P7K-F operates from -55°C to 125°C, while the BFC237341475 operates from -55°C to 105°C. All other electrical and mechanical parameters are identical.

Q: Are there any packaging differences?

A: The DMM2W4P7K-F is packaged in standard inventory format, while the BFC237341475 is supplied in Bulk packaging. Both are through-hole radial components with identical lead spacing and termination type.

Q: Can I mix these parts in the same production batch?

A: Yes, provided your application operates at or below 105°C. Both parts are electrically and mechanically compatible and meet identical compliance standards. Lead spacing and termination are identical, allowing use of the same PCB footprint.
