DMM2P1K-F Equivalent & Substitute Parts Reference

Part Overview

The DMM2P1K-F is a 0.1 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 250V DC voltage rating, ±10% tolerance, and polyester metallized dielectric construction. This radial through-hole component operates across -55°C to 125°C and is classified as Active product status. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained within the allowed parameter ranges for this film capacitor category.

Substitute Part Grouping Explanation

Substitute parts for the DMM2P1K-F are classified into three categories based on electrical and mechanical parameter alignment:

Direct Substitutes (Equivalent Specifications): Parts maintaining identical capacitance (0.1 µF), voltage rating (250V DC), tolerance (±10%), dielectric type (polyester metallized), mounting configuration (radial through-hole), and lead spacing (10.00mm). These parts are interchangeable without circuit redesign.

Upgrade Substitutes (Improved Tolerance or Voltage Rating): Parts with the same capacitance and voltage rating but featuring tighter tolerance (±5% instead of ±10%), or higher voltage ratings (400V DC) while maintaining 250V AC/DC compatibility. These provide enhanced performance margins.

Similar Substitutes (Dimensional or Series Variations): Parts from alternative manufacturer series with matching electrical specifications but different physical dimensions or lead spacing. These require PCB layout verification before implementation.

The following parameters determine substitution validity:

Capacitance value must equal 0.1 µF
Voltage rating must be 250V DC minimum
Dielectric must be polyester metallized
Mounting must be radial through-hole
Lead spacing must accommodate 10.00mm PCB hole patterns or be verified for compatibility
Operating temperature range must support -55°C to 125°C minimum
RoHS3 compliance must be maintained

Engineering Selection Recommendations

For Direct Replacement (No Circuit Redesign Required):

Select 160104K250D-F or 160104J250D-F when PCB layout accommodates the 13.00mm x 5.00mm footprint. Both maintain Active product status. The 160104J250D-F offers ±5% tolerance improvement over the original ±10% specification. Both parts are CDE manufactured and maintain full RoHS3 compliance and REACH unaffected status.

Select B32521C3104K000 or B32521C3104J000 when EPCOS-TDK sourcing is required. Both maintain 10.00mm lead spacing and Active product status. The B32521C3104J000 provides ±5% tolerance. Both are AEC-Q200 rated for automotive applications and maintain RoHS3 compliance.

For Voltage Margin Enhancement:

Select DME4P1K-F, B32521C6104J, or B32521C6104K when 400V DC rating is required for circuit protection margin. All three maintain 10.00mm lead spacing and -55°C to 125°C operating range. DME4P1K-F is Active status. B32521C6104J and B32521C6104K are marked Not For New Designs but remain available in inventory.

For Space-Constrained Applications:

Select DME2P1K-F when reduced physical dimensions are required (10.30mm x 5.80mm). This part maintains Active status and full temperature range but uses 7.50mm lead spacing, requiring PCB layout verification.

Product Status Considerations:

Parts marked Active status (DMM2P1K-F, 160104K250D-F, 160104J250D-F, DME4P1K-F, DME2P1K-F, B32521C3104K000, B32521C3104J000, B32521C3104J289) are recommended for new designs. Parts marked Not For New Designs (B32521C6104J, B32521C6104K, B32521C6104K289) are suitable for legacy system maintenance and repair only.

Frequently Asked Questions (FAQ)

Q: Can I substitute DMM2P1K-F with 160104K250D-F directly on the PCB?

A: Yes, if your PCB accommodates the 13.00mm x 5.00mm footprint with 10.00mm lead spacing. Both parts share identical electrical specifications (0.1 µF, 250V DC, ±10%, polyester metallized). Verify PCB hole pattern compatibility before assembly.

Q: What is the difference between ±10% and ±5% tolerance parts?

A: Tolerance defines the acceptable capacitance deviation from the nominal 0.1 µF value. ±10% allows 0.09 µF to 0.11 µF; ±5% allows 0.095 µF to 0.105 µF. Tighter tolerance (±5%) provides more precise capacitance for circuits requiring strict value control. Both are electrically compatible in applications tolerating the original ±10% specification.

Q: Why are some EPCOS parts marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued these parts for new product development. They remain available for existing inventory and legacy system support. For new designs, select Active status alternatives such as B32521C3104K000 or B32521C3104J000.

Q: Can I use a 400V rated capacitor in place of a 250V rated capacitor?

A: Yes. Higher voltage rating provides additional safety margin. DME4P1K-F (400V) and B32521C6104K (400V) are electrically compatible with 250V circuits. Physical dimensions differ; verify PCB layout compatibility. All other electrical parameters remain equivalent.

Q: What does lead spacing mean, and why does it matter?

A: Lead spacing is the distance between capacitor pins (10.00mm for most substitutes, 7.50mm for DME2P1K-F). This dimension must match PCB hole patterns. Mismatched spacing prevents proper component insertion. Verify your PCB design before selecting parts with non-standard spacing.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 Compliant status and REACH Unaffected designation, meeting environmental and regulatory requirements equivalent to the original DMM2P1K-F.

Q: What is the difference between Bulk and Tape & Box packaging?

A: Bulk packaging is loose components suitable for manual assembly or small-quantity applications. Tape & Box (TB) packaging uses reel format for automated pick-and-place assembly. Electrical specifications are identical; packaging selection depends on assembly process requirements.

Q: Can I substitute CDE parts with EPCOS-TDK parts?

A: Yes, when electrical specifications match. B32521C3104K000 and B32521C3104J000 are direct EPCOS-TDK equivalents to CDE 160104 series parts. Both manufacturers provide equivalent polyester metallized film capacitors with identical voltage, capacitance, and tolerance ratings. Verify supplier availability and lead time requirements.

Q: What is AEC-Q200 rating on EPCOS parts?

A: AEC-Q200 is an automotive electronics qualification standard. EPCOS B3252* series parts carrying this rating meet automotive reliability and performance requirements. This certification is not present on CDE DMM/160 series parts but does not affect electrical compatibility for general-purpose applications.
