DMM2P22K-F Equivalent & Substitute Parts Reference

Part Overview

The DMM2P22K-F is a 0.22 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 250V DC voltage rating and ±10% tolerance. This radial polyester metallized capacitor operates across a temperature range of -55°C to 125°C and is designed for general-purpose applications. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance can be achieved through alternative manufacturers or upgraded specifications while maintaining compatibility with the original application requirements.

Substitute Part Grouping Explanation

Substitution logic for the DMM2P22K-F is based on the following criteria:

Direct Substitutes maintain identical electrical specifications (0.22 µF, 250V DC, ±10% tolerance) with compatible physical dimensions and lead spacing (15.00mm). These parts are interchangeable without circuit redesign.

Upgrade Substitutes provide enhanced specifications such as tighter tolerance (±5% instead of ±10%), higher voltage ratings (400V or 450V DC), or improved temperature performance. These parts are electrically compatible and can replace the original part in applications where enhanced performance is acceptable.

Similar Parts share the same capacitance and voltage rating but differ in physical dimensions or lead spacing (10.00mm vs. 15.00mm). These require PCB layout verification before substitution.

All substitute candidates must maintain:

Identical capacitance value (0.22 µF)
Equal or higher DC voltage rating
Equal or tighter tolerance specification
Through-hole radial mounting configuration
ROHS3 compliance status

Engineering Selection Recommendations

Direct Substitution (No Circuit Redesign Required)

160224K250F-F serves as a direct electrical equivalent with identical voltage and tolerance specifications. This CDE part maintains Active product status. The operating temperature range is reduced to -55°C to 105°C compared to the original -55°C to 125°C specification. Selection of this part is appropriate when the application does not require operation above 105°C.

Upgrade Substitution (Enhanced Specifications)

160224J250F-F provides tighter tolerance (±5% vs. ±10%) while maintaining 250V DC rating and Active product status. This upgrade is suitable for applications requiring improved capacitance accuracy. Temperature range limitation to 105°C applies.

DME4P22K-F offers 400V DC rating with ±10% tolerance and extended temperature range (-55°C to 125°C). This CDE part is appropriate for applications requiring higher voltage margin or operation at elevated temperatures. Physical dimensions increase slightly but lead spacing remains compatible.

Cross-Manufacturer Substitution (EPCOS - TDK Electronics)

B32522C3224J000 provides equivalent 250V DC performance with ±5% tolerance and AEC-Q200 automotive rating. This part maintains the full -55°C to 125°C temperature range. Selection is appropriate for automotive applications requiring enhanced reliability certification.

B32522N6224J000 offers the highest voltage rating (450V DC) with ±5% tolerance and AEC-Q200 certification. This part is suitable for applications requiring maximum voltage headroom and automotive-grade reliability. Active product status confirms ongoing availability.

Parts Not Recommended for New Designs

B32522C6224J and B32522C6224K carry "Not For New Designs" status. While electrically compatible, these EPCOS parts should not be selected for new product development. Existing designs using these parts may continue with them, but new applications should select Active-status alternatives.

Lead Spacing Consideration

B32521C3224K000 features 10.00mm lead spacing compared to the standard 15.00mm. This part requires PCB layout verification and is classified as similar rather than direct substitute. Selection requires confirmation that PCB hole pattern accommodates the reduced spacing.

Frequently Asked Questions (FAQ)

A: 160224J250F-F provides tighter tolerance specification (±5% vs. ±10%), resulting in improved capacitance accuracy. This upgrade is beneficial for applications with strict capacitance tolerances. The 250V DC rating and 15.00mm lead spacing remain compatible. Temperature range is limited to 105°C.

Q: When should I select DME4P22K-F instead of the original part?

A: Select DME4P22K-F when your application requires higher voltage margin (400V vs. 250V DC) or operation at temperatures above 105°C. This CDE part maintains the full -55°C to 125°C temperature range and ±10% tolerance. Physical dimensions increase slightly but remain within typical PCB layout tolerances.

Q: Are EPCOS B32522 series parts compatible with the DMM2P22K-F?

A: EPCOS B32522 series parts are electrically compatible when specifications match. B32522C3224J000 (250V, ±5%) and B32522N6224J000 (450V, ±5%) are Active-status alternatives. Both maintain 15.00mm lead spacing and -55°C to 125°C temperature range. B32522C6224J and B32522C6224K carry "Not For New Designs" status and should not be selected for new applications.

Q: What does "Not For New Designs" status mean?

A: Parts marked "Not For New Designs" are still available and functional but are being phased out by the manufacturer. Existing designs using these parts may continue production. New product development should select Active-status alternatives to ensure long-term supply availability and manufacturer support.

Q: Can I use B32521C3224K000 as a substitute?

A: B32521C3224K000 is electrically compatible (0.22 µF, 250V DC, ±10%) but features 10.00mm lead spacing instead of 15.00mm. This requires PCB layout verification to confirm hole pattern compatibility. Physical dimensions are also reduced. Use only if your PCB accommodates the different lead spacing.

Q: Which substitute offers the best reliability for automotive applications?

A: B32522C3224J000 and B32522N6224J000 both carry AEC-Q200 automotive qualification. B32522N6224J000 provides the highest voltage rating (450V DC) with ±5% tolerance and Active product status, making it the preferred choice for automotive applications requiring enhanced reliability certification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts maintain ROHS3 compliance status, matching the original DMM2P22K-F specification. This ensures compatibility with environmental and regulatory requirements across all alternatives.
