DPM2P47K-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPM2P47K-F is a 0.47 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the DPM series. This radial through-hole component operates at 250V DC with polypropylene metallized dielectric construction. The part is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Film capacitors of this specification are essential in DC link filtering, DC filtering applications, and high-frequency switching circuits where low ESR and low ESL characteristics are required. Equivalent and substitute parts are identified to provide design flexibility, inventory alternatives, and supply chain continuity.

Substitute Part Grouping Explanation

Substitute parts for the DPM2P47K-F are identified based on strict electrical and mechanical parameter matching. The substitution logic requires:

Electrical Parameters (Non-Negotiable):

• Capacitance value: 0.47 µF (exact match)
• Tolerance: ±10% (matching or tighter tolerance acceptable)
• DC voltage rating: 250V minimum (equal or higher acceptable)
• Dielectric material: Polypropylene (PP), Metallized (must match for circuit performance)
• Operating temperature range: -55°C to 105°C minimum (equal or wider range acceptable)

Mechanical Parameters (Non-Negotiable):

• Mounting type: Through Hole Radial (must match for assembly compatibility)
• Lead spacing: 0.886" (22.50mm) (must match for PCB footprint)
• Termination: PC Pins (must match for soldering process)

Compliance Parameters:

• RoHS3 compliance required
• MSL rating: 1 (Unlimited) acceptable

The 474MPR250K qualifies as a direct substitute based on matching all critical electrical and mechanical parameters while maintaining regulatory compliance.

Engineering Selection Recommendations

474MPR250K as Direct Substitute:

The 474MPR250K is a qualified direct substitute for the DPM2P47K-F based on matching all critical electrical parameters: identical capacitance (0.47 µF), tolerance (±10%), DC voltage rating (250V), dielectric material (polypropylene metallized), operating temperature range (-55°C to 105°C), and mechanical specifications (through-hole radial, 22.50mm lead spacing, PC pin termination).

Both parts maintain Active product status and full RoHS3 compliance with MSL 1 rating. The substitute exhibits superior AC voltage rating (200V versus 160V), which provides additional design margin in AC filtering applications.

Physical dimensions show the substitute is more compact: narrower (8.50mm versus 10.00mm) and shorter (14.00mm versus 19.00mm seated height). This dimensional difference may provide PCB layout advantages in space-constrained designs while maintaining identical footprint compatibility through matching lead spacing.

Both parts are manufactured within the Cornell Dubilier family, ensuring consistent quality standards and performance characteristics. Selection between these parts should be based on inventory availability, packaging requirements (Bulk for 474MPR250K versus standard for DPM2P47K-F), and physical space constraints on the PCB.

Frequently Asked Questions (FAQ)

Q: Can the 474MPR250K replace the DPM2P47K-F in existing designs without PCB modification?

A: Yes. The 474MPR250K maintains identical lead spacing (22.50mm) and through-hole radial mounting configuration, ensuring direct PCB footprint compatibility. No design changes are required.

Q: What is the significance of the different physical dimensions between these parts?

A: The 474MPR250K is more compact (narrower and shorter) while maintaining identical electrical performance and lead spacing. This dimensional difference does not affect electrical function or PCB compatibility. The smaller package may provide layout advantages in space-constrained applications.

Q: Are both parts suitable for DC link and DC filtering applications?

A: Yes. Both the DPM2P47K-F and 474MPR250K are specified for DC link and DC filtering applications with identical capacitance, voltage rating, and polypropylene metallized dielectric construction.

Q: What is the difference between the AC voltage ratings?

A: The DPM2P47K-F is rated 160V AC, while the 474MPR250K is rated 200V AC. Both exceed the 250V DC rating requirement. The higher AC rating on the substitute provides additional design margin for AC filtering applications.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are RoHS3 compliant, REACH unaffected, and carry identical MSL 1 (Unlimited) moisture sensitivity ratings. Both are classified as Active products with equivalent regulatory status.

Q: What packaging formats are available?

A: The DPM2P47K-F is available in standard packaging with 1081 pieces in stock. The 474MPR250K is available in Bulk packaging with 1572 pieces in stock. Packaging selection depends on procurement and assembly requirements.

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

A: Yes. Both parts feature low ESR and low ESL characteristics suitable for high-frequency switching applications. The 474MPR250K is specified with low ESR performance, maintaining compatibility with the original part's switching circuit requirements.

Q: Is the ±10% tolerance acceptable for both parts?

A: Yes. Both parts carry ±10% tolerance specification. This tolerance is standard for film capacitors in this category and is acceptable for DC link, DC filtering, and high-frequency switching applications.
