Substitute Part Grouping Explanation

Substitution of the DPM2W2P2K is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 2.2 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 250V (minimum requirement; higher ratings acceptable)
• Voltage Rating - AC: 160V (minimum requirement; higher ratings acceptable)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Lead Spacing: 1.083" (27.50mm) (exact match required)
• Termination: PC Pins (exact match required)

Substitute parts must satisfy all parameters listed above. Physical dimensions, electrical characteristics, and environmental ratings must remain within specified tolerances to ensure functional and mechanical compatibility in the original application circuit.

Engineering Selection Recommendations

DPM2W2P2K-F is the direct active equivalent of the obsolete DPM2W2P2K. This substitute maintains identical electrical specifications, physical dimensions, and mechanical compatibility. The primary distinction is product status: DPM2W2P2K-F is currently in active production, whereas the original part is obsolete.

Additional compliance advantages of DPM2W2P2K-F include ROHS3 compliance and MSL rating of 1 (Unlimited), compared to the non-compliant RoHS status of the original part. These certifications support modern manufacturing and supply chain requirements.

For applications requiring the 2.2 µF, 250V DC film capacitor in radial through-hole configuration, DPM2W2P2K-F provides full functional and mechanical substitution with improved regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can DPM2W2P2K-F be used as a direct replacement for DPM2W2P2K?

A: Yes. DPM2W2P2K-F is electrically and mechanically identical to DPM2W2P2K. All electrical parameters, physical dimensions, lead spacing, and termination specifications are equivalent. The substitute is suitable for direct PCB mounting without circuit modification.

Q: What is the difference between DPM2W2P2K and DPM2W2P2K-F?

A: The primary differences are product status and regulatory compliance. DPM2W2P2K is obsolete; DPM2W2P2K-F is active production. DPM2W2P2K-F carries ROHS3 compliance and MSL rating 1, whereas the original part is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there physical dimension differences between these parts?
