DMT2D22K-F Film Capacitor: Equivalent & Substitute Parts

Part Overview

The DMT2D22K-F is a 2200 pF film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 250V DC operation with ±10% tolerance. This radial through-hole component utilizes polyester metallized dielectric technology and operates across the temperature range of -55°C to 125°C. The part is Active in product status and ROHS3 compliant. Substitute parts are identified when equivalent capacitance and voltage ratings are required but alternative manufacturers, improved tolerance specifications, or enhanced voltage performance are preferred for specific application requirements.

Substitute Part Grouping Explanation

Substitute parts for the DMT2D22K-F are classified into two categories based on substitution logic:

Upgrade Substitute (160222J1000C-F): This part maintains the identical capacitance value (2200 pF) and lead spacing (0.394" / 10.00mm) while providing enhanced electrical performance. The upgrade substitute offers superior voltage rating (1000V DC versus 250V DC), improved tolerance specification (±5% versus ±10%), and maintains through-hole radial mounting. Both parts use polyester metallized dielectric technology and are ROHS3 compliant. The upgrade substitute is suitable for applications requiring higher voltage margin or tighter capacitance tolerance.

Similar Substitute (B32529C3222K000): This part matches the capacitance (2200 pF), tolerance (±10%), and voltage rating (250V DC) of the original part. Manufactured by EPCOS - TDK Electronics, it uses polyester metallized dielectric in a stacked radial configuration. The similar substitute features a more compact physical footprint (0.287" L x 0.098" W versus 0.512" L x 0.217" W) and reduced lead spacing (0.197" versus 0.394"), making it suitable for space-constrained applications. This part carries AEC-Q200 automotive qualification and is ROHS3 compliant.

Substitution eligibility is determined by: matching capacitance value, voltage rating equal to or exceeding the original specification, tolerance equal to or tighter than ±10%, through-hole radial mounting configuration, and ROHS3 compliance status.

Engineering Selection Recommendations

For Direct Replacement (Same Electrical Performance): The B32529C3222K000 provides equivalent electrical specifications with identical capacitance (2200 pF), tolerance (±10%), and voltage rating (250V DC). This part is suitable for applications where the original DMT2D22K-F footprint cannot be accommodated due to PCB layout constraints. Both parts maintain ROHS3 compliance and Active product status. The B32529C3222K000 includes AEC-Q200 automotive qualification, making it appropriate for automotive applications.

For Enhanced Performance (Higher Voltage Margin): The 160222J1000C-F upgrade substitute provides 1000V DC rating with improved ±5% tolerance while maintaining the same lead spacing (0.394" / 10.00mm) as the original part. This substitute is selected when applications require higher voltage safety margin or when tighter capacitance tolerance improves circuit performance. The upgrade substitute is ROHS3 compliant and Active in product status. Operating temperature range is -55°C to 105°C, which is acceptable for most general-purpose applications.

For Space-Constrained Applications: The B32529C3222K000 offers the most compact physical footprint (7.30mm x 2.50mm) with reduced lead spacing (5.00mm), enabling use in densely populated PCB designs. This configuration maintains electrical equivalence while optimizing board real estate.

All substitute parts are ROHS3 compliant and Active in product status, ensuring regulatory compliance and ongoing manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the 160222J1000C-F be used as a direct replacement for the DMT2D22K-F? A: Yes. The 160222J1000C-F maintains identical capacitance (2200 pF) and lead spacing (10.00mm), with superior voltage rating (1000V DC) and tighter tolerance (±5%). The higher voltage rating provides additional safety margin. Both parts use polyester metallized dielectric and are ROHS3 compliant. The operating temperature range differs slightly (-55°C to 105°C versus -55°C to 125°C), which is acceptable for most applications.

Q: What are the physical differences between the DMT2D22K-F and B32529C3222K000? A: The B32529C3222K000 is significantly more compact (7.30mm x 2.50mm versus 13.00mm x 5.50mm) with reduced lead spacing (5.00mm versus 10.00mm). This smaller footprint requires PCB layout modification but provides equivalent electrical performance. The B32529C3222K000 uses a stacked radial configuration versus the standard radial design of the original part.

Q: Are all substitute parts ROHS3 compliant? A: Yes. Both the 160222J1000C-F and B32529C3222K000 are ROHS3 compliant, matching the compliance status of the original DMT2D22K-F.

Q: Which substitute part should be selected for automotive applications? A: The B32529C3222K000 carries AEC-Q200 automotive qualification, making it the appropriate choice for automotive applications. It maintains equivalent electrical specifications (2200 pF, ±10%, 250V DC) while meeting automotive reliability standards.

Q: Does the 160222J1000C-F require PCB layout changes? A: No. The 160222J1000C-F maintains the same lead spacing (10.00mm) as the original DMT2D22K-F, allowing direct PCB footprint compatibility. Physical dimensions are slightly reduced (13.00mm x 4.00mm versus 13.00mm x 5.50mm), which does not affect mounting.

Q: Can the B32529C3222K000 be used in high-temperature applications? A: Yes. The B32529C3222K000 operates across -55°C to 125°C, matching the original DMT2D22K-F temperature range. The 160222J1000C-F operates to 105°C, which is suitable for most applications but may not be appropriate for extreme high-temperature environments.

Q: What is the tolerance difference between the original part and substitutes? A: The DMT2D22K-F and B32529C3222K000 both specify ±10% tolerance. The 160222J1000C-F provides tighter ±5% tolerance, which reduces capacitance variance and may improve circuit performance in precision applications.
