DMM6P15K-F Equivalent & Substitute Parts

Part Overview

The DMM6P15K-F is a 0.15 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 630V DC voltage rating and ±10% tolerance. This radial through-hole component utilizes polyester metallized dielectric technology and operates across a temperature range of -55°C to 125°C. The part is classified as Active product status with ROHS3 compliance and REACH unaffected designation. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility parameters are maintained across the component's critical functional requirements.

Substitute Part Grouping Explanation

Substitute parts for the DMM6P15K-F are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

Capacitance value: 0.15 µF (exact match required)
Tolerance: ±10% (exact match required)
Voltage Rating - DC: 630V (exact match required)
Voltage Rating - AC: 250V (exact match required)
Dielectric Material: Polyester, Metallized (exact match required)

Mechanical Compatibility Criteria:

Mounting Type: Through Hole (exact match required)
Package / Case: Radial (exact match required)
Termination: PC Pins (exact match required)

Compliance Criteria:

RoHS Status: ROHS3 Compliant (exact match required)
Product Status: Active (exact match required)

Two substitute parts meet these criteria: DME6P15K-F (Cornell Dubilier Electronics) and QXK2J154KTPTZH (Nichicon). Both maintain identical electrical specifications and mounting characteristics while differing in physical dimensions and operating temperature ranges.

Engineering Selection Recommendations

DME6P15K-F Substitution: The DME6P15K-F maintains identical electrical specifications and operating temperature range as the DMM6P15K-F. Both components are manufactured by Cornell Dubilier Electronics and carry ROHS3 compliance. The primary distinction is physical footprint: the DME6P15K-F features reduced length (0.728" vs 1.024") and width (0.315" vs 0.394"), with modified lead spacing (0.591" vs 0.886"). This substitute is suitable for applications where PCB space constraints permit the smaller form factor and lead spacing accommodation.

QXK2J154KTPTZH Substitution: The QXK2J154KTPTZH (Nichicon) provides electrical equivalence with identical capacitance, tolerance, and voltage ratings. This substitute maintains the same lead spacing (0.886") as the main part, facilitating direct PCB footprint compatibility. The operating temperature range is narrower (-40°C to 105°C versus -55°C to 125°C). This substitute is suitable for applications operating within the -40°C to 105°C temperature envelope. Both parts carry ROHS3 compliance and Active product status.

Frequently Asked Questions (FAQ)

Q: Can DME6P15K-F be used as a direct replacement for DMM6P15K-F on existing PCBs?

A: Electrical substitution is valid; however, mechanical compatibility requires verification. The DME6P15K-F has different lead spacing (0.591" versus 0.886") and physical dimensions. PCB layout modification may be necessary to accommodate the smaller footprint.

Q: What is the primary difference between DMM6P15K-F and QXK2J154KTPTZH?

A: Both parts are electrically equivalent with identical capacitance (0.15 µF), tolerance (±10%), and voltage ratings (630V DC / 250V AC). The main differences are manufacturer (Cornell Dubilier versus Nichicon), operating temperature range (DMM6P15K-F: -55°C to 125°C; QXK2J154KTPTZH: -40°C to 105°C), and physical dimensions. Lead spacing is identical (0.886"), permitting direct PCB footprint compatibility.

Q: Are all three parts ROHS3 compliant?

A: Yes. DMM6P15K-F, DME6P15K-F, and QXK2J154KTPTZH all carry ROHS3 compliance certification and REACH unaffected status.

Q: Which substitute should be selected for applications requiring the full -55°C to 125°C temperature range?

A: The DME6P15K-F maintains the identical -55°C to 125°C operating temperature range as the DMM6P15K-F. The QXK2J154KTPTZH operates within a narrower range (-40°C to 105°C) and is not suitable for applications requiring the extended low-temperature specification.

Q: Can lead spacing differences affect circuit performance?

A: Lead spacing affects PCB layout and assembly compatibility, not electrical performance. The DME6P15K-F (0.591" spacing) requires PCB redesign. The QXK2J154KTPTZH (0.886" spacing) matches the main part and permits direct substitution without layout modification.
