DME2P82K Film Capacitor Equivalent & Substitute Parts

Part Overview

The DME2P82K is a 0.82 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the DME series. This radial through-hole component features polyester metallized dielectric construction with a 250V DC voltage rating and ±10% capacitance tolerance. The part is classified as obsolete, necessitating identification of active equivalent alternatives for ongoing procurement and design continuity. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement capability in existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete DME2P82K is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Equivalence Requirements:

• Capacitance value: 0.82 µF (identical)
• Capacitance tolerance: ±10% (identical)
• Voltage rating - DC: 250V (identical or higher)
• Voltage rating - AC: 160V (identical or higher)
• Dielectric material: Polyester, Metallized (identical)
• Operating temperature range: -55°C to 125°C (identical or wider)

Mechanical Compatibility Requirements:

• Mounting type: Through Hole (identical)
• Package configuration: Radial (identical)
• Lead spacing: 0.591" / 15.00mm (identical)
• Physical dimensions: 0.728" L x 0.276" W / 18.50mm x 7.00mm (identical)
• Termination: PC Pins (identical)

Only parts meeting all specified parameters are classified as direct substitutes. Compliance status and product availability are secondary considerations that do not affect substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

The DME2P82K-F is the direct substitute for the obsolete DME2P82K. Both parts are manufactured by Cornell Dubilier Electronics within the DME series and share identical electrical and mechanical specifications across all critical parameters.

Selection Basis:

The DME2P82K-F maintains complete parameter equivalence with the main part, ensuring pin-for-pin and form-factor compatibility. The substitute part is currently in active production status with confirmed inventory availability (714 pcs), whereas the main part is obsolete. The DME2P82K-F additionally provides ROHS3 compliance, representing an improvement in regulatory alignment compared to the non-compliant main part. Both parts carry identical REACH and ECCN classifications.

For applications requiring the 0.82 µF, 250V DC, polyester metallized film capacitor in radial through-hole configuration, the DME2P82K-F provides direct functional and mechanical replacement without design modification.

Frequently Asked Questions (FAQ)

Q: Can DME2P82K-F be used as a direct replacement for DME2P82K in existing designs?

A: Yes. The DME2P82K-F is electrically and mechanically identical to the DME2P82K across all specified parameters, including capacitance, voltage ratings, dielectric material, operating temperature range, physical dimensions, lead spacing, and termination type. Direct substitution is supported without circuit modification.

Q: What is the difference between DME2P82K and DME2P82K-F?

A: The primary differences are product status and compliance certification. The DME2P82K is obsolete and RoHS non-compliant, while the DME2P82K-F is an active production part with ROHS3 compliance. All electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: The main part (DME2P82K) is specified with standard packaging, while the substitute (DME2P82K-F) is supplied in bulk packaging. Both maintain identical component specifications and radial through-hole form factor. Packaging type does not affect electrical or mechanical compatibility.

Q: What are the key parameters that define substitution eligibility for this capacitor?

A: Substitution eligibility is determined by: capacitance value (0.82 µF), tolerance (±10%), DC voltage rating (250V), AC voltage rating (160V), dielectric material (polyester metallized), operating temperature range (-55°C to 125°C), mounting type (through hole), package configuration (radial), lead spacing (15.00mm), physical dimensions (18.50mm x 7.00mm), and termination type (PC pins). All parameters must match exactly.

Q: Is the DME2P82K-F suitable for new designs?

A: Yes. The DME2P82K-F is an active production part suitable for new designs requiring a 0.82 µF, 250V DC polyester metallized film capacitor in radial through-hole configuration. The part carries ROHS3 compliance and is available in production quantities.

Q: What is the lead spacing for these capacitors?

A: The lead spacing is 0.591 inches (15.00mm) for both the DME2P82K and DME2P82K-F, ensuring compatibility with standard PCB hole patterns designed for radial through-hole film capacitors in this series.
