DPM4P47K-F Equivalent & Substitute Parts

Part Overview

The DPM4P47K-F is a 0.47 µF polypropylene film capacitor rated for 400V DC operation, manufactured by Cornell Dubilier Electronics (CDE). This radial through-hole capacitor is designed for DC link and high-frequency switching applications where low equivalent series resistance (ESR) and low equivalent series inductance (ESL) are critical. The part is active, in full stock (717 pcs), and fully compliant with RoHS3 and REACH regulations. Alternative models are necessary to accommodate varying inventory levels, lead times, packaging preferences, and specific mechanical or performance constraints in system designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DPM4P47K-F is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 0.47 µF (exact match required)
• Tolerance: ±10% (exact match required)
• DC Voltage Rating: 400V minimum (equal or higher acceptable)
• AC Voltage Rating: 220V minimum (equal or higher acceptable)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required for electrical consistency)
• Operating Temperature Range: -55°C to +105°C minimum (equal or broader acceptable)
• Mounting Type: Through Hole (exact match required for board compatibility)
• Package Type: Radial (exact match required for form factor)
• Termination: PC Pins (exact match required for connection compatibility)
• Lead Spacing: 1.083" (27.50mm) (exact match required for PCB footprint compatibility)
• Compliance: RoHS3 Compliant and REACH Unaffected (minimum standards for modern applications)

The 474MPR400K (Cornell Dubilier / Illinois Capacitor, MPR Series) meets all critical substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution: The 474MPR400K is a direct, pin-for-pin compatible equivalent to the DPM4P47K-F for all DC link and high-frequency switching applications within the specified operating parameters.

Compliance & Certification: Both parts maintain identical RoHS3 Compliance and REACH Unaffected status, meeting modern regulatory requirements for electronic component design and assembly.

Electrical Performance: Both capacitors provide equivalent electrical characteristics for the specified application envelope. The 474MPR400K delivers documented ESR of 376 mOhms, confirming low ESR performance critical for DC filtering and switching circuit operation.

Mechanical Fit: While the 474MPR400K exhibits slightly reduced physical dimensions (31.00mm length vs. 32.00mm, 10.50mm width vs. 11.00mm), it maintains identical lead spacing (27.50mm) and PCB footprint compatibility. The lower seated height (16.50mm vs. 21.00mm) provides additional board clearance in space-constrained designs.

Inventory & Supply: The 474MPR400K offers superior stock availability (1139 pcs vs. 717 pcs), supporting production continuity and supply chain resilience.

Frequently Asked Questions (FAQ)

Q: Can the 474MPR400K be used as a direct replacement for the DPM4P47K-F without PCB layout modification?

A: Yes. Both parts maintain identical lead spacing (27.50mm) and radial through-hole termination. No PCB footprint changes are required. The slightly reduced physical dimensions of the 474MPR400K improve clearance margins but do not impact electrical connection or mounting compatibility.

Q: Are the electrical operating characteristics identical between these two capacitors?

A: Yes, within the specified parameters. Both parts are 0.47 µF ±10%, rated for 400V DC / 220V AC operation, use polypropylene metallized dielectric, and feature low ESR performance. Both operate across -55°C to +105°C without derating within this range.

Q: Why does the 474MPR400K have a lower seated height than the DPM4P47K-F?

A: The 474MPR400K (16.50mm) is mechanically optimized for compact form factor while maintaining all electrical and functional equivalence. This is a design variation within the same capacitor family and offers practical advantages in space-constrained applications.

Q: What is the significance of the documented 376 mOhms ESR on the 474MPR400K?

A: The 376 mOhms ESR confirms low equivalent series resistance performance, critical for DC filtering and high-frequency switching applications. This specification is typical for modern polypropylene metallized film capacitors in this voltage class and validates suitability for the intended circuit role.

Q: Are both parts RoHS3 and REACH compliant?

A: Yes. Both the DPM4P47K-F and 474MPR400K maintain RoHS3 Compliance and REACH Unaffected status, meeting regulatory requirements for modern electronics manufacturing and international supply chain operations.

Q: Which part should be selected between DPM4P47K-F and 474MPR400K?

A: Selection depends on supply availability and design priorities. For applications where space clearance is a consideration, the 474MPR400K offers a lower profile (16.50mm vs. 21.00mm seated height). For immediate availability within standard stock levels, verify current inventory with your distributor. Both parts are electrically and mechanically equivalent for the specified application envelope.
