Substitute Part Grouping Explanation

Substitution of the obsolete DME2W2P7K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match the following criteria:

Electrical Parameters:

• Capacitance: 2.7 µF (exact match)
• Tolerance: ±10% (exact match)
• Voltage Rating (DC): 250V (exact match)
• Voltage Rating (AC): 160V (exact match)
• Dielectric Material: Polyester, Metallized (exact match)
• Operating Temperature Range: -55°C to 125°C (exact match)

Mechanical Parameters:

• Mounting Type: Through Hole (exact match)
• Package Type: Radial (exact match)
• Physical Dimensions: 26.00mm L × 10.00mm W (exact match)
• Height (Seated Max): 17.50mm (exact match)
• Lead Spacing: 22.50mm (exact match)
• Termination: PC Pins (exact match)

The DME2W2P7K-F meets all substitution criteria and is classified as an active product, making it suitable for direct replacement in applications currently using the obsolete DME2W2P7K.

Parameter Comparison

Engineering Selection Recommendations

The DME2W2P7K-F is the direct equivalent substitute for the obsolete DME2W2P7K. Selection of the DME2W2P7K-F is based on the following factors:

Product Status: The DME2W2P7K-F is classified as an active product, ensuring continued availability and supply chain reliability. The original DME2W2P7K is obsolete and subject to discontinuation.

Electrical and Mechanical Equivalence: All electrical parameters (capacitance, tolerance, voltage ratings, dielectric material, temperature range) and mechanical parameters (dimensions, lead spacing, mounting type, termination) are identical between the two parts.

Regulatory Compliance: The DME2W2P7K-F is ROHS3 compliant, whereas the original part is RoHS non-compliant. This improvement in compliance status supports long-term regulatory adherence in manufacturing and procurement processes.

Inventory Availability: The DME2W2P7K-F has 866 units in stock, compared to 775 units of the obsolete part, providing superior procurement assurance.
