DME10P15K-F Equivalent & Substitute Parts

Part Overview

The DME10P15K-F is a 0.15 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 1000V DC voltage rating, designed for general-purpose applications. This radial through-hole component features polyester metallized dielectric construction and operates across a temperature range of -55°C to 125°C. The part is currently active in production with 980 units in stock. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when specific application requirements necessitate alternative dielectric materials or tolerance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DME10P15K-F is determined by strict equivalence in the following parameters:

Critical Parameters (Must Match):

• Capacitance: 0.15 µF
• Voltage Rating - DC: 1000V (1kV)
• Voltage Rating - AC: 250V
• Mounting Type: Through Hole
• Package / Case: Radial
• Lead Spacing: 0.886" (22.50mm)
• Termination: PC Pins

Allowable Variations:

• Tolerance: ±10% (substitute may have tighter tolerance such as ±5%)
• Dielectric Material: Polyester or Polypropylene metallized film
• Operating Temperature Range: Substitute minimum -55°C and maximum ≥105°C
• Physical dimensions: Minor variations acceptable within radial package constraints
• Manufacturer: Different manufacturer acceptable if all critical parameters match

The substitute part R75QN31504000J from KEMET meets all critical parameter requirements while offering a tighter tolerance specification and alternative dielectric material composition.

Parameter Comparison

Engineering Selection Recommendations

Both the DME10P15K-F and R75QN31504000J are active production parts with ROHS3 compliance and REACH unaffected status, making either suitable for new designs and existing applications requiring regulatory compliance.

The DME10P15K-F offers a higher maximum operating temperature of 125°C compared to the R75QN31504000J at 105°C. Selection should be based on application temperature requirements.

The R75QN31504000J provides a tighter tolerance specification (±5% versus ±10%), which may be advantageous in applications requiring closer capacitance accuracy. The KEMET part also carries AEC-Q200 automotive qualification, suitable for automotive applications.

Dielectric material differences exist: the CDE part uses polyester while the KEMET substitute uses polypropylene. Both are metallized film constructions rated for the same voltage and frequency specifications provided in the input data.

Physical dimensions show minor variations within acceptable radial package tolerances. The KEMET part is slightly shorter in seated height (0.732" versus 0.787"), which may provide advantages in space-constrained PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can R75QN31504000J replace DME10P15K-F in existing designs?

A: Yes. Both parts share identical capacitance (0.15 µF), voltage ratings (1000V DC / 250V AC), lead spacing (0.886"), mounting type (through hole radial), and termination (PC pins). Physical dimensions are within acceptable radial package variations.

Q: What is the difference between polyester and polypropylene dielectric materials?

A: Both are metallized film dielectrics meeting the specified voltage and frequency ratings. The choice between them depends on application-specific requirements not provided in the input parameters. Consult application datasheets for dielectric-specific performance characteristics.

Q: Does the tighter tolerance of R75QN31504000J (±5%) affect compatibility?

A: No. Tighter tolerance is a specification improvement. The ±5% tolerance of the KEMET part is within the ±10% allowance of the CDE part, ensuring functional compatibility.

Q: Is the lower maximum operating temperature of R75QN31504000J (105°C vs 125°C) a limitation?

A: Only if the application requires sustained operation above 105°C. For applications operating at or below 105°C, both parts are equivalent. Verify application temperature requirements before selection.

Q: Are both parts suitable for automotive applications?

A: The R75QN31504000J carries AEC-Q200 automotive qualification. The DME10P15K-F is specified for general-purpose applications. Selection depends on automotive compliance requirements.

Q: What is the significance of the slight height difference (0.787" vs 0.732")?

A: The R75QN31504000J is shorter when seated on the PCB. This may provide advantages in space-constrained designs but does not affect electrical compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both DME10P15K-F and R75QN31504000J are ROHS3 compliant and REACH unaffected.
