Parameter Comparison

Engineering Selection Recommendations

DME6W1P2K-F is the direct functional equivalent and substitute for the obsolete DME6W1P2K. Both components are manufactured by Cornell Dubilier Electronics within the DME series and share identical electrical and mechanical specifications.

Key Distinctions:

The DME6W1P2K-F carries an Active product status, ensuring ongoing availability and manufacturing support. The original DME6W1P2K is classified as Obsolete and should not be specified for new designs or long-term procurement.

The DME6W1P2K-F achieves ROHS3 compliance, whereas the DME6W1P2K is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the DME6W1P2K-F is the appropriate selection.

Both components maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99), indicating equivalent regulatory treatment for export and environmental compliance purposes.

Frequently Asked Questions (FAQ)

Q: Can the DME6W1P2K-F be used as a direct replacement for the DME6W1P2K?

A: Yes. The DME6W1P2K-F is a direct substitute. All electrical parameters (capacitance, voltage ratings, tolerance, dielectric material, temperature range) and mechanical parameters (dimensions, lead spacing, mounting type, termination) are identical. The component can be substituted without circuit modification or PCB redesign.

Q: What is the primary reason to transition from DME6W1P2K to DME6W1P2K-F?

A: The DME6W1P2K is obsolete and no longer manufactured. The DME6W1P2K-F is the active production equivalent from the same manufacturer and series, ensuring component availability and supply chain continuity.

Q: Are there compliance differences between these two parts?

A: Yes. The DME6W1P2K-F is ROHS3 compliant, while the DME6W1P2K is RoHS non-compliant. For applications requiring RoHS compliance, the DME6W1P2K-F must be specified.

Q: Will the DME6W1P2K-F fit the same PCB footprint as the DME6W1P2K?

A: Yes. Both components have identical physical dimensions (31.00mm L × 13.50mm W × 23.00mm H) and lead spacing (27.50mm). No PCB layout modifications are required.

Q: Are the electrical performance characteristics identical?

A: Yes. Both components are rated for 630V DC and 250V AC operation with 1.2 µF capacitance at ±10% tolerance. Operating temperature range, dielectric material, and all other electrical specifications are identical.
