Engineering Selection Recommendations

The R73TN21504000J from KEMET is a qualified substitute for the DPPM12S15K-F based on the following engineering criteria:

Electrical Compatibility: Both components share identical capacitance values (0.015 µF) and dielectric material composition (polypropylene metallized). The KEMET substitute provides a higher DC voltage rating (1600V versus 1200V), which ensures operation within safe margins in the specified application. The AC voltage rating of 450V on the substitute meets the 475V requirement of the original specification.

Mechanical Compatibility: Both parts are radial through-hole components with PC pin terminations, ensuring direct board-level compatibility. Physical dimensions differ slightly, but both are designed for standard radial capacitor footprints.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH Unaffected status, satisfying environmental and regulatory requirements. The KEMET part carries AEC-Q200 automotive qualification, providing additional reliability assurance.

Tolerance and Temperature Performance: The KEMET substitute offers tighter tolerance (±5% versus ±10%) and an extended lower operating temperature limit (-55°C versus -40°C), providing enhanced performance margins in temperature-sensitive applications.

Product Status: Both components are active production items with confirmed inventory availability, ensuring supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the R73TN21504000J directly replace the DPPM12S15K-F in existing designs?

A: Yes. Both components share identical capacitance (0.015 µF), dielectric material (polypropylene metallized), mounting type (through-hole radial), and termination style (PC pins). The substitute meets or exceeds all electrical specifications of the original part.

Q: What are the physical dimension differences between these parts?

A: The DPPM12S15K-F measures 1.220" L x 0.413" W with a maximum seated height of 0.768" and lead spacing of 1.043". The R73TN21504000J measures 1.043" L x 0.335" W with a maximum seated height of 0.673" and lead spacing of 0.886". Both are radial configurations suitable for standard through-hole PCB layouts, though board-level spacing verification is necessary.

Q: Does the higher voltage rating of the substitute part affect circuit performance?

A: No. The higher DC voltage rating (1600V versus 1200V) of the KEMET substitute provides additional safety margin without affecting circuit operation. The component will function identically at the specified operating voltage of 1200V DC.

Q: Are there tolerance differences between these parts?

A: Yes. The DPPM12S15K-F has a tolerance of ±10%, while the R73TN21504000J has a tolerance of ±5%. The tighter tolerance of the substitute part provides improved capacitance accuracy without affecting compatibility.

Q: What is the temperature operating range difference?

A: The DPPM12S15K-F operates from -40°C to 105°C, while the R73TN21504000J operates from -55°C to 105°C. The extended lower temperature range of the substitute provides additional operational flexibility in cold-environment applications.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the DPPM12S15K-F and R73TN21504000J are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: What additional certifications does the substitute part carry?

A: The R73TN21504000J carries AEC-Q200 automotive qualification, indicating compliance with automotive industry reliability and quality standards. This certification is not listed for the original DPPM12S15K-F.
