DPM4S47K-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPM4S47K-F is a 0.047 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the DPM series. This radial polypropylene metallized capacitor is rated for 400V DC operation and is designed for DC link and DC filtering applications in high-frequency switching circuits. The part is currently in active production status with 977 pieces available in new original inventory.

Substitute parts are identified when equivalent electrical performance can be achieved within the allowed parameter tolerances for the application, while maintaining compatibility with the through-hole radial mounting configuration and PC pin termination standard.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DPM4S47K-F is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance value: 0.047 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Dielectric material: Polypropylene (PP), Metallized (exact match required)
• Mounting type: Through Hole, Radial (exact match required)
• Termination: PC Pins (exact match required)
• Lead spacing: 0.591" (15.00mm) (exact match required)
• Operating temperature range: -55°C ~ 105°C (exact match required)

Allowable Parameter Variance:

• Voltage Rating - DC: Substitute must equal or exceed 400V DC
• Physical dimensions (length, width, height): Minor variations permitted within standard radial package tolerances
• RoHS and MSL compliance: Substitute must maintain or exceed compliance level

The substitute part 473MPR630K meets all mandatory matching parameters and exceeds the voltage rating requirement, making it electrically and mechanically compatible with the DPM4S47K-F.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The 473MPR630K substitute part is electrically and mechanically compatible with the DPM4S47K-F based on the following engineering factors:

1. Electrical Equivalence: Both parts share identical capacitance (0.047 µF), tolerance (±10%), dielectric material (polypropylene metallized), and operating temperature range (-55°C ~ 105°C). The substitute's 630V DC rating exceeds the 400V requirement, providing additional voltage margin.

2. Mechanical Compatibility: Both parts feature identical lead spacing (0.591" / 15.00mm), through-hole radial mounting configuration, and PC pin termination. Physical dimension variations (width 0.335" vs. 0.315"; height 0.532" vs. 0.591") remain within standard radial package tolerances and do not affect PCB footprint compatibility.

3. Regulatory Compliance: Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating, meeting current environmental and moisture handling standards.

4. Production Status: Both parts are in active production with confirmed inventory availability, ensuring supply chain continuity.

Application Suitability:

The 473MPR630K is suitable for DC link and DC filtering applications in high-frequency switching circuits where the DPM4S47K-F is specified. The higher voltage rating of the substitute provides enhanced reliability margin in applications subject to voltage transients or overvoltage conditions.

Frequently Asked Questions (FAQ)

Q: Can the 473MPR630K be used as a direct replacement for the DPM4S47K-F?

A: Yes. The 473MPR630K meets all mandatory electrical and mechanical parameters required for direct substitution. Capacitance, tolerance, dielectric material, mounting type, termination style, and lead spacing are identical. The substitute's higher voltage rating (630V vs. 400V) is compatible with applications designed for the original part.

Q: What is the significance of the higher voltage rating on the substitute part?

A: The 473MPR630K's 630V DC rating exceeds the DPM4S47K-F's 400V DC rating. This provides additional voltage margin and is compatible with circuits designed for 400V operation. Higher voltage-rated capacitors do not negatively affect performance in lower-voltage applications.

Q: Are there physical dimension differences between these parts?

A: Minor physical dimension variations exist. The 473MPR630K is 0.020" (0.50mm) wider and 0.059" (1.50mm) shorter than the DPM4S47K-F. These variations remain within standard radial package tolerances and do not affect PCB footprint compatibility, as lead spacing is identical (0.591" / 15.00mm).

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the DPM4S47K-F and 473MPR630K are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, meeting current environmental and handling requirements.

Q: What applications are these capacitors designed for?

A: Both parts are specified for DC link and DC filtering applications in high-frequency switching circuits. The polypropylene metallized dielectric and low ESR characteristics make them suitable for power conversion and energy storage functions.

Q: Is inventory availability a consideration in part selection?

A: Both parts are in active production. The 473MPR630K has higher inventory availability (2486 pieces) compared to the DPM4S47K-F (977 pieces), which may be relevant for high-volume procurement scenarios.
