Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete DME1W1P2K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Parameters:

• Capacitance value: 1.2 µF
• Tolerance: ±10%
• Voltage rating (DC): 100V
• Voltage rating (AC): 65V
• Dielectric material: Polyester, Metallized
• Operating temperature range: -55°C ~ 125°C

Mechanical Parameters:

• Mounting type: Through Hole
• Package configuration: Radial
• Lead spacing: 0.591" (15.00mm)
• Termination style: PC Pins
• Physical dimensions: 0.728" L x 0.217" W (18.50mm x 5.50mm)
• Maximum seated height: 0.504" (12.80mm)

Compliance Parameters:

• RoHS3 Compliance
• REACH Unaffected status

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The DME1W1P2K-F is a direct parametric equivalent to the obsolete DME1W1P2K. Both parts are manufactured by Cornell Dubilier Electronics within the same DME series and share identical electrical specifications, mechanical dimensions, and compliance certifications.

The primary distinction is product status: the original DME1W1P2K is obsolete, while the DME1W1P2K-F maintains active production status. This substitution is appropriate for new designs, production continuity, and field replacements where the original part is no longer available.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications subject to environmental and hazardous substance restrictions. The identical physical footprint, lead spacing, and termination style ensure direct compatibility with existing printed circuit board layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the DME1W1P2K-F be used as a direct replacement for the DME1W1P2K?

A: Yes. The DME1W1P2K-F is a parametric equivalent with identical electrical ratings, mechanical dimensions, and compliance certifications. Direct substitution is supported without circuit modification or board redesign.

Q: Are there any differences in physical dimensions between these parts?

A: No. Both parts share identical dimensions: 0.728" L x 0.217" W (18.50mm x 5.50mm) with a maximum seated height of 0.504" (12.80mm) and lead spacing of 0.591" (15.00mm). PCB footprints are interchangeable.

Q: What is the significance of the "-F" suffix in the DME1W1P2K-F part number?

A: The "-F" suffix indicates a variant designation within the DME series. The suffix does not alter electrical performance or mechanical compatibility; it reflects manufacturing or packaging updates while maintaining full parametric equivalence.

Q: Are both parts RoHS compliant?

A: Yes. Both the DME1W1P2K and DME1W1P2K-F are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.

Q: Why is the original DME1W1P2K listed as obsolete?

A: Product obsolescence reflects manufacturing discontinuation by Cornell Dubilier Electronics. The active DME1W1P2K-F provides continued availability of equivalent functionality within the same product series.

Q: Can these parts be used in applications requiring 100V DC operation?

A: Yes. Both parts are rated for 100V DC operation with a 65V AC rating and maintain full performance across the operating temperature range of -55°C to 125°C.
