Engineering Selection Recommendations

The 154MWR400K is electrically and functionally equivalent to the MMP4P15K-F for general-purpose applications requiring 0.15 µF capacitance at 400V DC. Both parts maintain identical electrical specifications, dielectric material composition, and compliance certifications (ROHS3 and REACH).

Selection Considerations:

Physical dimensions differ between the two parts. The MMP4P15K-F measures 11.50mm × 6.50mm × 22.00mm, while the 154MWR400K measures 8.50mm diameter × 19.00mm length. PCB layout and mechanical clearance requirements must accommodate these dimensional differences.

Operating temperature ranges differ. The MMP4P15K-F operates across -55°C to 125°C, while the 154MWR400K operates across -40°C to 105°C. Applications requiring operation below -40°C or above 105°C must use the MMP4P15K-F.

Both parts are active products with current manufacturing status and full compliance documentation. The 154MWR400K has higher inventory availability (4,259 units) compared to the MMP4P15K-F (1,138 units).

Frequently Asked Questions (FAQ)

Q: Can the 154MWR400K directly replace the MMP4P15K-F in all applications?

A: The 154MWR400K is electrically equivalent for general-purpose applications. However, physical dimensions differ, requiring verification of PCB layout compatibility. Additionally, the operating temperature range of the 154MWR400K (-40°C to 105°C) is narrower than the MMP4P15K-F (-55°C to 125°C), so applications requiring extended temperature operation must use the MMP4P15K-F.

Q: What are the critical electrical parameters that must match for substitution?

A: Capacitance (0.15 µF), tolerance (±10%), voltage rating (400V DC / 200V AC), and dielectric material (polyester, metallized) must be identical. Both parts meet these requirements.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. No compliance differences exist.

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

A: The primary differences are physical dimensions and operating temperature range. The 154MWR400K is physically smaller and has a narrower operating temperature specification.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For standard general-purpose applications with standard temperature ranges, either part is suitable. For space-constrained designs, the 154MWR400K offers a smaller footprint. For extended temperature operation or maximum temperature headroom, the MMP4P15K-F is required.
