DMM4P15K-F Equivalent & Substitute Parts Reference

Part Overview

The DMM4P15K-F is a 0.15 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 400V DC voltage rating and ±10% tolerance. This radial through-hole component utilizes polyester metallized dielectric technology and operates across a temperature range of -55°C to 125°C. The part is currently in active production status with 963 units in stock.

Substitute parts are identified when equivalent electrical performance can be achieved while maintaining compatibility with the application's circuit requirements. Alternative models may be necessary due to inventory availability, voltage rating upgrades, tolerance improvements, or dimensional constraints specific to PCB layout requirements.

Engineering Selection Recommendations

DME6P15K-F (Upgrade Substitute - Recommended for New Designs)

The DME6P15K-F is a direct upgrade substitute with identical capacitance, tolerance, and operating temperature range. The elevated 630V DC rating provides enhanced voltage margin for applications subject to transient overvoltage conditions. Both parts maintain ROHS3 compliance and identical lead spacing for PCB compatibility. The DME6P15K-F is in active production status, ensuring long-term availability. Physical dimensions are slightly larger (0.728" L x 0.315" W versus 0.709" L x 0.276" W), requiring verification of available PCB space.

B32522C6154J (Upgrade Substitute - Legacy Status)

The B32522C6154J offers improved ±5% tolerance compared to the ±10% specification of the DMM4P15K-F while maintaining 400V DC rating and identical lead spacing. This EPCOS part is manufactured using polyester PET metallized stacked dielectric technology. However, this part carries "Not For New Designs" status, limiting its application to legacy system maintenance or replacement scenarios. The compact physical dimensions (0.709" L x 0.236" W) may provide space advantages in constrained layouts.

154MMR400K (Similar Substitute - Active Status)

The 154MMR400K provides identical electrical specifications (0.15 µF, ±10%, 400V DC) with matching lead spacing and through-hole radial configuration. This part is manufactured by Cornell Dubilier / Illinois Capacitor and maintains active production status. The operating temperature range is restricted to -40°C to 105°C, which is narrower than the DMM4P15K-F specification. Physical dimensions are compact (0.728" L x 0.217" W), offering potential space savings. This substitute is suitable for applications where the reduced temperature range is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the DME6P15K-F be used as a direct replacement for the DMM4P15K-F?

A: Yes. The DME6P15K-F is electrically and mechanically compatible. Both parts share identical capacitance (0.15 µF), tolerance (±10%), operating temperature range (-55°C to 125°C), lead spacing (15.00mm), and termination type (PC pins). The DME6P15K-F provides higher voltage rating (630V versus 400V), which is a beneficial upgrade. Physical dimensions are slightly larger; verify PCB layout clearance before substitution.

Q: What is the difference between the B32522C6154J and the DMM4P15K-F?

A: Both parts have identical capacitance (0.15 µF) and voltage rating (400V DC). The B32522C6154J offers tighter tolerance (±5% versus ±10%) and uses polyester PET metallized stacked dielectric technology. The B32522C6154J is smaller (0.709" L x 0.236" W versus 0.709" L x 0.276" W). The critical difference is product status: B32522C6154J is marked "Not For New Designs," restricting its use to legacy applications.

Q: Is the 154MMR400K suitable for all applications where the DMM4P15K-F is used?

A: The 154MMR400K is suitable for applications where the operating temperature range of -40°C to 105°C is acceptable. The DMM4P15K-F operates to -55°C and 125°C. If your application requires the full -55°C to 125°C range, the 154MMR400K is not appropriate. All other electrical and mechanical parameters are compatible.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All substitute parts listed (DME6P15K-F, B32522C6154J, and 154MMR400K) are ROHS3 compliant, matching the compliance status of the DMM4P15K-F.

Q: What is the significance of lead spacing in substitution?

A: Lead spacing (15.00mm for all listed parts) determines PCB footprint compatibility. All substitute parts maintain identical 0.591" (15.00mm) lead spacing, ensuring they fit existing PCB hole patterns without layout modification.

Q: Can I use the B32522C6154J in new product designs?

A: No. The B32522C6154J carries "Not For New Designs" status. This designation indicates the manufacturer has discontinued active development and support for this part. Use this part only for maintenance, repair, or replacement of existing legacy systems. For new designs, select DME6P15K-F or 154MMR400K.

Q: How do physical dimensions affect substitution?

A: Physical dimensions determine whether a substitute part fits within available PCB space. The DMM4P15K-F measures 0.709" L x 0.276" W (height 0.551"). The DME6P15K-F is slightly larger (0.728" L x 0.315" W, height 0.689"), while the B32522C6154J and 154MMR400K are more compact. Verify clearance around the capacitor location before substitution.
