DMM2P15K-F Equivalent & Substitute Parts

Part Overview

The DMM2P15K-F is a 0.15 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 -55°C to 125°C and is designed for general-purpose applications. The part is currently active in production with 840 pieces in stock.

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. Substitutes are necessary when the primary part becomes unavailable, when design upgrades require enhanced voltage ratings, or when alternative tolerance specifications are acceptable.

Engineering Selection Recommendations

Direct Substitution (Same Electrical and Mechanical Specifications):

BFC237341154 (Vishay Beyschlag/Draloric/BC Components) is a direct equivalent substitute with identical electrical specifications (0.15 µF, ±10%, 250V DC, 160V AC) and matching lead spacing (0.591"). This part is active in production and RoHS3 compliant. Physical dimensions are slightly reduced (0.689" L vs. 0.709" L), which provides improved PCB space efficiency. Operating temperature range is -55°C to 105°C, which meets the minimum requirement of -55°C to 125°C for most applications, though it does not extend to the upper limit. This substitute is suitable for applications where the upper temperature limit of 105°C is acceptable.

Upgrade Substitution (Enhanced Voltage Rating, Same Lead Spacing):

DME6P15K-F (Cornell Dubilier Electronics) provides a voltage upgrade to 630V DC while maintaining the same 0.15 µF capacitance, ±10% tolerance, and 0.591" lead spacing. This part is active in production with higher inventory availability (1192 pcs). Physical dimensions are slightly larger (0.728" L x 0.315" W vs. 0.709" L x 0.276" W), and seated height increases to 0.689". This substitute is appropriate for applications requiring enhanced voltage margin or operating in higher voltage environments.

Upgrade Substitution (Tighter Tolerance, Same Voltage Rating):

B32522C3154J000 (EPCOS - TDK Electronics) offers tighter tolerance (±5% vs. ±10%) while maintaining 250V DC and 160V AC ratings with matching 0.591" lead spacing. This part is active in production and rated for automotive applications (AEC-Q200). Physical dimensions are reduced (0.709" L x 0.197" W), providing improved PCB space efficiency. This substitute is suitable for applications requiring tighter capacitance tolerance.

Upgrade Substitution (Higher Voltage with Tighter Tolerance):

B32522C6154J (EPCOS - TDK Electronics) combines 400V DC voltage rating with ±5% tolerance. Lead spacing matches at 0.591". However, this part is marked "Not For New Designs," indicating it is in end-of-life status. While 16900 pieces are in inventory, this part should not be selected for new designs. It may be considered only for legacy system maintenance or repair where existing designs already incorporate this part number.

Compact Form Factor Substitution (Different Lead Spacing):

DME2P15K-F (Cornell Dubilier Electronics) provides equivalent electrical specifications (0.15 µF, ±10%, 250V DC, 160V AC) in a significantly reduced physical package (0.406" L x 0.236" W). However, lead spacing is reduced to 0.295" (7.50mm) versus the original 0.591" (15.00mm). This part is suitable only for applications where PCB hole patterns can accommodate the reduced lead spacing. Inventory availability is high (4130 pcs). This substitute requires PCB redesign and is not a direct drop-in replacement.

Frequently Asked Questions (FAQ)

Q: Can DME2P15K-F be used as a direct replacement for DMM2P15K-F?

A: No. While DME2P15K-F has identical electrical specifications (0.15 µF, ±10%, 250V DC, 160V AC), the lead spacing differs significantly (0.295" vs. 0.591"). Direct substitution requires matching lead spacing for PCB hole pattern compatibility. DME2P15K-F requires PCB redesign and is not a drop-in replacement.

Q: What is the difference between the CDE DMM and DME series?

A: Both series are manufactured by Cornell Dubilier Electronics and use polyester metallized dielectric. The DMM series (DMM2P15K-F) and DME series (DME2P15K-F, DME6P15K-F) differ in physical dimensions and voltage ratings. The DME2P15K-F matches the electrical specifications of DMM2P15K-F but in a smaller package with different lead spacing. The DME6P15K-F offers higher voltage rating (630V DC) in a larger package.

Q: Can B32522C6154J be used in new designs?

A: No. B32522C6154J is marked "Not For New Designs" by the manufacturer EPCOS - TDK Electronics, indicating end-of-life status. While inventory is currently available (16900 pcs), this part should not be selected for new product designs. It may be used only for maintenance or repair of existing systems already incorporating this part number.

Q: What is the significance of the ±5% tolerance in B32522C3154J000 compared to the ±10% tolerance of DMM2P15K-F?

A: Tolerance specifies the acceptable deviation from the nominal capacitance value. The ±5% tolerance of B32522C3154J000 provides tighter capacitance accuracy compared to the ±10% tolerance of DMM2P15K-F. For a 0.15 µF capacitor, ±10% tolerance allows 0.135 µF to 0.165 µF, while ±5% tolerance allows 0.1425 µF to 0.1575 µF. Tighter tolerance is beneficial for applications requiring precise capacitance values but is not necessary for general-purpose applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (DME6P15K-F, DME2P15K-F, B32522C3154J000, B32522C6154J, BFC237341154) are RoHS3 compliant and REACH Unaffected, matching the regulatory compliance of the original DMM2P15K-F.

Q: What is the maximum operating temperature difference between BFC237341154 and DMM2P15K-F?

A: BFC237341154 operates to 105°C maximum, while DMM2P15K-F operates to 125°C maximum. The difference is 20°C at the upper temperature limit. BFC237341154 is suitable for applications where the operating environment does not exceed 105°C. For applications requiring operation up to 125°C, BFC237341154 is not appropriate.

Q: Why is the physical size of B32522C3154J000 smaller than DMM2P15K-F despite identical electrical ratings?

A: Physical size differences result from different manufacturing designs and dielectric material configurations. B32522C3154J000 uses a metallized-stacked dielectric configuration, while DMM2P15K-F uses standard metallized polyester. The stacked configuration allows more efficient use of space while maintaining the same electrical performance. Smaller physical size provides PCB space advantages but does not affect electrical compatibility.

Q: Can DME6P15K-F be used in place of DMM2P15K-F without circuit modification?

A: Yes. DME6P15K-F has the same capacitance (0.15 µF), tolerance (±10%), and lead spacing (0.591") as DMM2P15K-F. The higher voltage rating (630V DC vs. 250V DC) is a beneficial upgrade that does not require circuit modification. Physical dimensions are slightly larger (0.728" L x 0.315" W vs. 0.709" L x 0.276" W), so PCB layout space must be verified. No electrical circuit changes are required.
