DPM2W3P3K: Equivalent & Substitute Parts

Part Overview

The DPM2W3P3K is a 3.3 µF film capacitor rated for 250V DC operation with polypropylene metallized dielectric, designed for through-hole radial mounting. This component is classified as obsolete product status, necessitating the identification of functionally equivalent alternatives for new designs and procurement continuity. The substitute part DPM2W3P3K-F provides direct functional equivalence with updated compliance certifications and active product availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by equivalence across the following critical electrical and mechanical parameters: capacitance value (3.3 µF), capacitance tolerance (±10%), DC voltage rating (250V), AC voltage rating (160V), dielectric material (polypropylene metallized), operating temperature range (-55°C to 105°C), mounting configuration (through-hole radial), and lead spacing (1.575" or 40.00mm). The substitute part DPM2W3P3K-F satisfies all these requirements, with the primary differences being product lifecycle status (active versus obsolete), physical height reduction, and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The DPM2W3P3K-F is the direct functional equivalent for applications requiring a 3.3 µF, 250V DC polypropylene metallized film capacitor. Selection of the DPM2W3P3K-F is appropriate for new designs and procurement of replacement components, as it maintains electrical equivalence with the original DPM2W3P3K while offering active product status and current compliance certifications. The DPM2W3P3K-F achieves RoHS3 compliance and carries MSL rating of 1 (unlimited moisture sensitivity level), addressing contemporary manufacturing and environmental standards. The physical height reduction (27.00mm versus 30.00mm) presents a potential benefit for space-constrained PCB layouts while maintaining identical lead spacing and termination characteristics. For legacy systems using the obsolete DPM2W3P3K, direct substitution is supported by the equivalence across all critical electrical parameters and mechanical form factors.

Frequently Asked Questions (FAQ)

Q: Can DPM2W3P3K-F directly replace DPM2W3P3K in existing assemblies? A: Yes. Both parts are electrically and mechanically equivalent across all functional parameters: 3.3 µF capacitance, ±10% tolerance, 250V DC rating, 160V AC rating, polypropylene metallized dielectric, identical operating temperature range, through-hole radial mounting, and 1.575" lead spacing. The DPM2W3P3K-F requires no circuit modifications for substitution.

Q: What is the significance of the height difference between these parts? A: The DPM2W3P3K-F height of 27.00mm (versus 30.00mm for the original) provides improved compatibility with tighter PCB clearance requirements. This dimension reduction does not affect electrical performance or lead spacing, making it beneficial for compact designs while maintaining identical mounting characteristics.

Q: Are there compliance or regulatory differences between these parts? A: Yes. The DPM2W3P3K is RoHS non-compliant, while the DPM2W3P3K-F achieves RoHS3 compliance. The substitute part also carries an MSL rating of 1 (unlimited), versus not applicable for the original. These certifications align with current manufacturing and environmental regulations.

Q: What applications are these capacitors designed for? A: Both parts are specified for DC Link, DC Filtering, High Frequency, and Switching applications. The low ESR and low ESL characteristics support their use in power conversion, filtering, and high-frequency signal processing circuits.

Q: Are there any mechanical considerations for PCB layout? A: Lead spacing is identical at 1.575" (40.00mm) for both parts, ensuring equivalent footprint compatibility. Verify PCB hole spacing and clearances to this dimension. The reduced height of the DPM2W3P3K-F may be verified during design review for space-critical applications.
