DME6S39K Film Capacitor Equivalent & Substitute Parts

Part Overview

The DME6S39K is a 0.039 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the DME series. This radial through-hole component is rated for 630V DC and 250V AC operation with polyester metallized dielectric construction. The part is classified as obsolete, necessitating identification of active equivalent alternatives for continued system support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete DME6S39K is determined by strict equivalence across all electrical and mechanical parameters. The substitute must maintain identical specifications in capacitance value, voltage ratings, dielectric composition, temperature operating range, physical dimensions, lead spacing, and termination type. The DME6S39K-F qualifies as a direct substitute based on complete parameter alignment with the original part, with the distinction that it maintains active product status and current manufacturing compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The DME6S39K-F is the direct functional equivalent for applications currently utilizing the obsolete DME6S39K. Both parts are manufactured by Cornell Dubilier Electronics within the DME series and share identical electrical and mechanical specifications. The primary distinction is product lifecycle status: the DME6S39K-F maintains active manufacturing status with ROHS3 compliance certification, whereas the original DME6S39K is obsolete and RoHS non-compliant. For new designs or system redesigns, the DME6S39K-F is the appropriate selection. For legacy system maintenance where original part specifications must be preserved, the DME6S39K-F provides complete electrical and mechanical compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can DME6S39K-F be used as a direct replacement for DME6S39K in existing assemblies?

A: Yes. The DME6S39K-F is electrically and mechanically identical to the DME6S39K. All electrical parameters (capacitance, voltage ratings, tolerance, temperature range) and physical dimensions (lead spacing, package size, termination type) are equivalent. No circuit modifications or PCB layout changes are required.

Q: What is the difference between DME6S39K and DME6S39K-F?

A: The primary differences are product status and compliance certification. The DME6S39K is obsolete and RoHS non-compliant. The DME6S39K-F is an active product with ROHS3 compliance. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: The DME6S39K-F is supplied in bulk packaging, whereas the original DME6S39K packaging format is not specified. Both parts use identical radial through-hole package construction with 0.394" (10.00mm) lead spacing and PC pin termination.

Q: What compliance certifications apply to the substitute part?

A: The DME6S39K-F carries ROHS3 compliance certification and is REACH Unaffected. Both parts share the same ECCN (EAR99) and HTSUS (8532.25.0070) classifications.

Q: Is the operating temperature range the same for both parts?

A: Yes. Both the DME6S39K and DME6S39K-F operate across the identical temperature range of -55°C to 125°C.
