Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DPM2S47K-F are identified based on strict electrical and mechanical compatibility criteria. The substitution logic requires:

Mandatory Matching Parameters:

• Capacitance value: 0.047 µF (exact match required)
• Tolerance: ±10% (substitute tolerance must not exceed this range)
• Dielectric material: Polypropylene (PP), Metallized (exact match required)
• Mounting type: Through Hole Radial (exact match required)
• Lead spacing: 0.394" (10.00mm) (exact match required for PCB compatibility)

Allowable Upgrade Parameters:

• Voltage Rating - DC: Substitute must equal or exceed 250V
• Voltage Rating - AC: Substitute must equal or exceed 160V
• Operating temperature range: Substitute must maintain -55°C ~ 105°C minimum
• Physical dimensions: Substitute may vary within industry standard tolerances for radial packages
• RoHS compliance: Substitute must maintain ROHS3 Compliant status

The 473MPR400K qualifies as a direct substitute because it maintains all mandatory parameters while providing an upgraded DC voltage rating of 400V, exceeding the 250V requirement of the primary part.

Parameter Comparison

Engineering Selection Recommendations

The 473MPR400K is a qualified substitute for the DPM2S47K-F based on the following engineering criteria:

Electrical Compatibility: Both parts maintain identical capacitance (0.047 µF) and tolerance (±10%), ensuring equivalent circuit performance. The substitute's higher voltage rating (400V DC vs. 250V DC) provides additional design margin without affecting circuit operation in applications rated for 250V DC.

Mechanical Compatibility: Lead spacing is identical at 0.394" (10.00mm), ensuring direct PCB hole pattern compatibility. The substitute is physically shorter (0.433" vs. 0.551" seated height), which presents no compatibility issue for through-hole mounting and may provide advantages in space-constrained layouts.

Compliance and Certification: Both parts maintain ROHS3 compliance and identical moisture sensitivity levels (MSL 1 - Unlimited), ensuring regulatory and environmental compatibility.

Product Availability: Both parts maintain Active product status with current inventory (705 units for DPM2S47K-F; 859 units for 473MPR400K), supporting reliable sourcing.

Application Suitability: Both parts are rated for DC Link, DC Filtering, and high-frequency switching applications with low ESR and low ESL characteristics, maintaining functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can the 473MPR400K be used as a direct replacement for the DPM2S47K-F in all applications?

A: Yes. The 473MPR400K maintains all mandatory electrical and mechanical parameters. The higher voltage rating (400V vs. 250V) provides additional design margin and does not create compatibility issues in circuits designed for 250V operation.

Q: What is the significance of the different physical heights (0.551" vs. 0.433")?
