Substitute Part Grouping Explanation

Substitute parts for the DPM4P15K-F are identified based on strict electrical and mechanical compatibility criteria. The substitution logic is as follows:

Electrical Compatibility Requirements:

• Capacitance value must be identical: 0.15 µF
• Tolerance must be ±10% or tighter
• DC voltage rating must be equal to or greater than 400V
• AC voltage rating must be equal to or greater than 220V
• Dielectric material must be Polypropylene (PP), Metallized to maintain frequency response and ESR characteristics
• Operating temperature range must encompass -55°C to 105°C

Mechanical Compatibility Requirements:

• Mounting type must be Through Hole
• Package configuration must be Radial
• Lead spacing must be 0.886" (22.50 mm) to match PCB hole patterns
• Physical dimensions must allow installation in the same board space

Regulatory and Quality Requirements:

• RoHS3 compliance required
• MSL rating of 1 or better
• Active product status preferred for long-term availability

The 154MPR630K meets all substitution criteria and qualifies as a direct equivalent.

Engineering Selection Recommendations

Primary Selection: DPM4P15K-F

The DPM4P15K-F is the specified part for applications requiring exactly 400V DC and 220V AC ratings. This part is active in production, RoHS3 compliant, and maintains MSL-1 rating for unlimited shelf life. Use this part when the circuit design specifies the DPM series or when 400V DC rating is the design requirement.

Substitute Selection: 154MPR630K

The 154MPR630K qualifies as a direct substitute when the DPM4P15K-F is unavailable or when higher voltage margin is required. This part provides:

• Identical capacitance (0.15 µF) and tolerance (±10%)
• Higher voltage ratings (630V DC / 250V AC) providing additional safety margin
• Identical lead spacing (0.886") and radial package configuration
• Same operating temperature range (-55°C to 105°C)
• Identical dielectric material (Polypropylene, Metallized)
• Active production status with higher inventory availability (1233 pcs)
• Full RoHS3 and MSL-1 compliance

Both parts are manufactured by Cornell Dubilier or affiliated entities, ensuring consistent quality and performance standards. The 154MPR630K is suitable for direct board-level replacement without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the 154MPR630K replace the DPM4P15K-F in my circuit?

A: Yes. The 154MPR630K is electrically and mechanically compatible. It has identical capacitance (0.15 µF), tolerance (±10%), and lead spacing (0.886"). The higher voltage ratings (630V DC vs. 400V DC) provide additional safety margin without affecting circuit operation. Both parts use identical polypropylene metallized dielectric material and operate across the same temperature range (-55°C to 105°C).

Q: What are the key differences between these two parts?

A: The primary differences are voltage ratings and physical dimensions. The 154MPR630K is rated for 630V DC and 250V AC compared to the DPM4P15K-F at 400V DC and 220V AC. The 154MPR630K has a slightly larger width (0.433" vs. 0.315") and lower seated height (0.669" vs. 0.709"). Both differences are within typical PCB layout tolerances for radial capacitor mounting.

Q: Are both parts RoHS compliant?

A: Yes. Both the DPM4P15K-F and 154MPR630K are ROHS3 compliant and carry MSL-1 (Unlimited) moisture sensitivity ratings, meeting current regulatory requirements for electronic component manufacturing.

Q: What applications are these capacitors suitable for?

A: Both parts are specified for DC link and DC filtering applications in high-frequency switching circuits. The low ESR and low ESL characteristics make them suitable for power supply filtering, inverter circuits, and switching power supply applications.

Q: Does the higher voltage rating of the 154MPR630K affect performance?

A: No. Higher voltage rating does not degrade performance in lower-voltage applications. The 154MPR630K operates identically to the DPM4P15K-F when used in 400V DC circuits. The higher rating provides additional design margin and component reliability.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes, with minor layout consideration. Both parts have identical lead spacing (0.886") and radial package configuration. The 154MPR630K has slightly different physical dimensions (0.433" width vs. 0.315", and 0.669" height vs. 0.709"), but these differences are within standard PCB layout tolerances for radial capacitor mounting.

Q: Which part should I specify for new designs?

A: For new designs, specify based on your circuit voltage requirements. If 400V DC is sufficient, either part is acceptable. If higher voltage margin is desired, specify the 154MPR630K. Both parts are active in production with stable long-term availability.
