DMT2P68K-F Equivalent & Substitute Parts

Part Overview

The DMT2P68K-F is a 0.68 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE), designed for general-purpose applications requiring polyester metallized dielectric construction. This radial through-hole component operates across a temperature range of -55°C to 125°C and is rated for 250V DC operation. The part is currently in active production status with ROHS3 compliance and REACH unaffected certification. Substitute parts are identified when equivalent electrical performance can be maintained within the specified parameter tolerances while accommodating different physical packaging or series designations.

Substitute Part Grouping Explanation

Substitution of the DMT2P68K-F is permissible with the DME2P68K-F based on the following electrical and mechanical equivalence criteria:

Electrical Equivalence:

• Identical capacitance value: 0.68 µF
• Identical tolerance specification: ±10%
• Identical DC voltage rating: 250V
• Identical dielectric material: Polyester, Metallized
• Identical operating temperature range: -55°C to 125°C
• AC voltage rating of 160V (DME2P68K-F) exceeds the 125V AC requirement of the main part

Mechanical Compatibility:

• Both parts utilize radial through-hole mounting with PC pin termination
• Both parts are manufactured by Cornell Dubilier Electronics (CDE)
• Physical dimensions differ; lead spacing differs between series

Compliance Equivalence:

• Both parts maintain ROHS3 compliance
• Both parts are REACH unaffected
• Both parts carry identical ECCN and HTSUS classifications

Parameter Comparison

Engineering Selection Recommendations

The DME2P68K-F qualifies as an electrical and compliance equivalent to the DMT2P68K-F. Both parts are manufactured by Cornell Dubilier Electronics and maintain identical electrical specifications for capacitance, tolerance, DC voltage rating, dielectric material, and operating temperature range. Both parts carry active product status and maintain ROHS3 compliance with REACH unaffected certification.

The primary consideration for substitution is mechanical fit. The DME2P68K-F features a reduced physical footprint (18.50mm x 6.50mm versus 28.70mm x 16.00mm) and lower seated height (15.00mm versus 23.40mm). The lead spacing differs significantly: 15.00mm for the DME2P68K-F versus 25.00mm for the DMT2P68K-F. PCB layout verification is necessary to confirm that the substitute part's lead spacing accommodates existing through-hole pad patterns. If the original PCB design requires the 25.00mm lead spacing of the DMT2P68K-F, the DME2P68K-F cannot be used without PCB modification.

The DME2P68K-F's AC voltage rating of 160V exceeds the 125V AC specification of the main part, providing additional margin in AC applications.

Frequently Asked Questions (FAQ)

Q: Can the DME2P68K-F be used as a direct replacement for the DMT2P68K-F?

A: Electrical substitution is valid. Both parts share identical capacitance (0.68 µF), tolerance (±10%), DC voltage rating (250V), dielectric material (polyester metallized), and operating temperature range (-55°C to 125°C). However, mechanical compatibility depends on PCB layout. The lead spacing differs: DME2P68K-F uses 15.00mm spacing while DMT2P68K-F uses 25.00mm spacing. Verify that existing through-hole pad patterns accommodate the substitute part's lead spacing before implementation.

Q: What are the key electrical parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: capacitance value (0.68 µF), tolerance specification (±10%), DC voltage rating (250V), dielectric material (polyester metallized), and operating temperature range (-55°C to 125°C). The DME2P68K-F meets all these criteria. AC voltage rating is an additional consideration; the substitute's 160V AC rating exceeds the main part's 125V AC requirement.

Q: Does the DME2P68K-F meet the same compliance requirements?

A: Yes. Both the DMT2P68K-F and DME2P68K-F are ROHS3 compliant and REACH unaffected. Both carry identical ECCN (EAR99) and HTSUS (8532.25.0070) classifications.

Q: What is the primary difference between these two parts?

A: The primary differences are physical dimensions and lead spacing. The DME2P68K-F is more compact (18.50mm x 6.50mm versus 28.70mm x 16.00mm) with lower seated height (15.00mm versus 23.40mm) and different lead spacing (15.00mm versus 25.00mm). Electrical performance and compliance are equivalent.

Q: Is the smaller size of the DME2P68K-F an advantage?

A: The reduced footprint and lower profile of the DME2P68K-F may provide advantages in space-constrained applications. However, substitution requires PCB layout compatibility verification due to the different lead spacing. If the original design requires 25.00mm lead spacing, the compact dimensions of the substitute cannot be utilized without PCB modification.

Q: Are both parts currently available?

A: Yes. Both the DMT2P68K-F (1073 pcs in stock) and DME2P68K-F (1595 pcs in stock) are listed as active products with current inventory availability.
