Key Parameters

Substitute Part Grouping Explanation

Substitution of the DMT2D47K-F is determined by strict equivalence in the following parameters: capacitance value (4700 pF), tolerance (±10%), dielectric material (polyester, metallized), mounting type (through hole radial), lead spacing (10.00mm), and termination style (PC pins). Substitute parts must maintain these core electrical and mechanical characteristics.

Voltage rating elevation is permitted when the application circuit operates below the original rated voltage. Operating temperature range differences are acceptable when the application environment remains within the substitute part's specified limits. Physical dimensions may vary within the radial package category provided lead spacing remains constant at 10.00mm.

The identified substitutes are classified as follows:

Upgrade Substitute (Higher Voltage Rating): 160472K630C-F provides elevated DC voltage capability (630V) while maintaining identical capacitance, tolerance, and lead spacing.

Similar Substitute (Intermediate Voltage Rating): BFC237251472 offers intermediate DC voltage rating (400V) with comparable physical and electrical characteristics.

Engineering Selection Recommendations

DMT2D47K-F Selection Criteria: Use the original DMT2D47K-F when the application requires the extended operating temperature range of -55°C to 125°C and operates at or below 250V DC / 125V AC. This part maintains Active product status and ROHS3 compliance.

160472K630C-F Selection Criteria: Select the 160472K630C-F upgrade substitute when the application circuit operates below 250V DC but benefits from elevated voltage margin (630V DC capability). This part is suitable for designs requiring higher voltage headroom. Note the reduced maximum operating temperature of 105°C and compact physical dimensions (9.50mm seated height versus 12.40mm for the main part). Lead spacing remains constant at 10.00mm, ensuring PCB compatibility.

BFC237251472 Selection Criteria: Select the BFC237251472 similar substitute when sourcing from Vishay Beyschlag/Draloric/BC Components is preferred or when the application operates below 400V DC. This part offers intermediate voltage rating and compact form factor (10.00mm seated height). Maximum operating temperature is 105°C. The MKT372 series designation indicates Long Life feature classification.

All three parts maintain ROHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification, supporting regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the 160472K630C-F replace the DMT2D47K-F in all applications?

A: The 160472K630C-F is electrically compatible for applications operating below 250V DC. However, verify that the application environment does not exceed 105°C, as this substitute has a lower maximum operating temperature than the original part. Lead spacing is identical (10.00mm), ensuring PCB footprint compatibility. Physical dimensions are more compact.

Q: What is the primary difference between the upgrade and similar substitutes?

A: The 160472K630C-F (upgrade) provides the highest DC voltage rating at 630V and is manufactured by CDE, matching the original manufacturer. The BFC237251472 (similar) offers 400V DC rating and is manufactured by Vishay Beyschlag/Draloric/BC Components. Both maintain identical capacitance, tolerance, and lead spacing.

Q: Are there any PCB layout considerations when substituting parts?

A: All three parts maintain 10.00mm lead spacing, allowing direct PCB footprint compatibility. However, physical dimensions differ: the main part measures 13.00mm x 6.00mm with 12.40mm seated height, while both substitutes measure approximately 13.00mm x 4.00mm and 12.50mm x 4.00mm with seated heights of 9.50mm to 10.00mm. Verify clearance in confined spaces.

Q: Do all parts meet the same compliance standards?

A: Yes. The DMT2D47K-F, 160472K630C-F, and BFC237251472 are all ROHS3 compliant, REACH Unaffected, and classified as EAR99 for export control purposes.

Q: What is the operating temperature consideration for substitution?

A: The original DMT2D47K-F operates from -55°C to 125°C. Both substitutes operate from -55°C to 105°C. If the application requires operation above 105°C, only the original part is suitable.

Q: Can these parts be used interchangeably in high-frequency applications?

A: All three parts are specified for general-purpose applications with polyester, metallized dielectric construction. Frequency-dependent performance characteristics are not provided in the technical parameters. Consult detailed frequency response data for high-frequency circuit applications.
