DMM1W6P8K-F Equivalent & Substitute Parts

Part Overview

The DMM1W6P8K-F is a 6.8 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 100V DC operation with polyester metallized dielectric construction. This radial through-hole component is designed for general-purpose applications and maintains active product status with full ROHS3 compliance and REACH unaffected certification.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the allowed parameter specifications for this product category. The DME2W6P8K-F represents an upgrade option with enhanced voltage rating capability while preserving core electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DMM1W6P8K-F is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance value: 6.8 µF
• Tolerance: ±10%
• Dielectric material: Polyester, Metallized
• Mounting type: Through Hole
• Package type: Radial
• Termination: PC Pins
• Lead spacing: 1.083 inches (27.50 mm)
• Operating temperature range: -55°C to 125°C

Allowable Variation Parameters:

• Voltage rating (DC and AC): Substitute parts may exceed the original voltage rating without compromising compatibility
• Physical dimensions (length, width, height): Minor variations are acceptable provided lead spacing and mounting footprint remain unchanged
• Packaging format: Variations in packaging presentation (Bulk vs. standard) do not affect electrical or mechanical compatibility

The DME2W6P8K-F qualifies as a substitute because it maintains all mandatory matching parameters while providing enhanced voltage rating (250V DC / 160V AC versus 100V DC / 65V AC).

Parameter Comparison

Engineering Selection Recommendations

DMM1W6P8K-F Selection Criteria: Select the DMM1W6P8K-F when circuit design specifications require a 100V DC / 65V AC rated capacitor with 6.8 µF capacitance. This part maintains active product status with 612 units in current inventory. Full ROHS3 compliance and REACH unaffected certification confirm regulatory alignment for industrial and commercial applications.

DME2W6P8K-F Selection Criteria: Select the DME2W6P8K-F when higher voltage margin is required within the same footprint and electrical specifications. The 250V DC / 160V AC rating provides enhanced safety margin in applications subject to voltage transients or design margin requirements. This part maintains active product status with 1567 units in current inventory. Full ROHS3 compliance and REACH unaffected certification confirm regulatory alignment. Physical dimensions are reduced (0.886" height versus 1.024" height), providing potential PCB layout advantages.

Both parts are manufactured by Cornell Dubilier Electronics (CDE) and carry identical compliance certifications. Selection between these parts depends solely on circuit voltage requirements and available PCB space.

Frequently Asked Questions (FAQ)

Q: Can DME2W6P8K-F replace DMM1W6P8K-F in existing designs?

A: Yes. The DME2W6P8K-F maintains identical capacitance (6.8 µF), tolerance (±10%), dielectric material (polyester metallized), mounting type (through hole radial), lead spacing (1.083 inches), and operating temperature range (-55°C to 125°C). The substitute part is electrically and mechanically compatible with the original design footprint.

Q: What is the primary difference between these parts?

A: The DME2W6P8K-F provides higher voltage rating (250V DC / 160V AC) compared to the DMM1W6P8K-F (100V DC / 65V AC). Both parts deliver identical 6.8 µF capacitance. The substitute part also features reduced physical height (0.886 inches versus 1.024 inches).

Q: Are both parts RoHS compliant?

A: Yes. Both DMM1W6P8K-F and DME2W6P8K-F are ROHS3 compliant and REACH unaffected, confirming regulatory compliance for industrial and commercial applications.

Q: Does lead spacing remain identical between these parts?

A: Yes. Both parts maintain 1.083 inches (27.50 mm) lead spacing, ensuring PCB footprint compatibility without modification.

Q: Which part should be selected for new designs?

A: Selection depends on circuit voltage requirements. If the application operates at or below 100V DC / 65V AC, either part is suitable. If higher voltage margin is desired or if circuit conditions may exceed 100V DC / 65V AC, the DME2W6P8K-F is the appropriate selection.
