Equivalent & Substitute Parts for DME2S82K

Part Overview

The DME2S82K is a 0.082 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, which necessitates identification of active equivalent alternatives for ongoing procurement and system maintenance. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement without circuit redesign.

Substitute Part Grouping Explanation

Substitution of the obsolete DME2S82K is based on strict equivalence across all electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Equivalence Requirements:

• Capacitance value: 0.082 µF (exact match)
• Tolerance: ±10% (exact match)
• Voltage Rating DC: 250V (minimum requirement)
• Voltage Rating AC: 160V (minimum requirement)
• Dielectric Material: Polyester, Metallized (exact match)
• Operating Temperature Range: -55°C to 125°C (minimum requirement)

Mechanical Equivalence Requirements:

• Mounting Type: Through Hole (exact match)
• Package / Case: Radial (exact match)
• Lead Spacing: 0.295" / 7.50mm (exact match)
• Physical Dimensions: 0.406" L x 0.197" W / 10.30mm x 5.00mm (exact match)
• Height - Seated (Max): 0.315" / 8.00mm (exact match)
• Termination: PC Pins (exact match)

The DME2S82K-F meets all substitution criteria and is classified as an active product, making it suitable for direct replacement in applications currently using the obsolete DME2S82K.

Engineering Selection Recommendations

The DME2S82K-F is the direct equivalent substitute for the obsolete DME2S82K. Selection of the DME2S82K-F is based on the following engineering factors:

Product Status: The DME2S82K is classified as obsolete, creating supply chain risk. The DME2S82K-F maintains active product status with confirmed inventory availability, ensuring long-term procurement viability.

Electrical Compatibility: All electrical parameters are identical between the main part and substitute, including capacitance, tolerance, voltage ratings, dielectric material, and operating temperature range. No circuit redesign or performance adjustment is required.

Mechanical Compatibility: Physical dimensions, lead spacing, mounting type, and package configuration are identical. The substitute part is a direct drop-in replacement requiring no PCB layout modifications.

Regulatory Compliance: The DME2S82K-F achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. This improvement aligns with current regulatory requirements for electronic components in many jurisdictions. Both parts maintain REACH Unaffected status and EAR99 export classification.

Packaging: The DME2S82K-F is supplied in bulk packaging, which may differ from the original part's packaging configuration. Verify packaging requirements for your procurement process.

Frequently Asked Questions (FAQ)

Q: Can the DME2S82K-F be used as a direct replacement for the DME2S82K?

A: Yes. The DME2S82K-F is electrically and mechanically identical to the DME2S82K across all specified parameters. It functions as a direct drop-in replacement without requiring circuit modifications or PCB redesign.

Q: What is the primary reason for substitution?

A: The DME2S82K is classified as obsolete. The DME2S82K-F is the active equivalent from the same manufacturer and series, ensuring continued component availability and supply chain stability.

Q: Are there any differences in electrical performance between the two parts?

A: No. Both parts have identical capacitance (0.082 µF), tolerance (±10%), voltage ratings (250V DC / 160V AC), dielectric material (polyester metallized), and operating temperature range (-55°C to 125°C).

Q: Will the DME2S82K-F fit the existing PCB footprint?

A: Yes. The substitute part has identical physical dimensions (0.406" L x 0.197" W), lead spacing (0.295" / 7.50mm), and height (0.315" maximum). No PCB layout changes are necessary.

Q: What is the difference in RoHS compliance?

A: The original DME2S82K is RoHS non-compliant, while the DME2S82K-F is ROHS3 compliant. This represents an improvement in regulatory alignment for new designs and applications subject to RoHS requirements.

Q: Is the packaging different between the two parts?

A: The DME2S82K-F is supplied in bulk packaging. Confirm that bulk packaging meets your procurement and handling requirements. Contact your supplier for packaging options if needed.

Q: Are both parts from the same manufacturer?

A: Yes. Both the DME2S82K and DME2S82K-F are manufactured by Cornell Dubilier Electronics (CDE) and belong to the DME series.

Q: What is the lead spacing specification?

A: The lead spacing is 0.295 inches (7.50 millimeters) for both parts. This specification is critical for PCB footprint compatibility and must match your board design.
