Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DMT1D68K is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 6800 pF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 100V (minimum requirement; higher ratings acceptable)
• Voltage Rating - AC: 65V (minimum requirement; higher ratings acceptable)
• Dielectric Material: Polyester, Metallized (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Physical Dimensions: 0.512" L x 0.209" W (13.00mm x 5.30mm) (exact match required)
• Termination: PC Pins (exact match required)

Substitute parts must satisfy all parameters listed above to ensure mechanical and electrical compatibility with existing PCB layouts and circuit designs.

Parameter Comparison

Engineering Selection Recommendations

The DMT1D68K-F serves as the direct substitute for the obsolete DMT1D68K. Both components are manufactured by Cornell Dubilier Electronics within the DMT series and maintain identical electrical and mechanical specifications across all critical parameters.

Product Status Consideration: The DMT1D68K is classified as obsolete, while the DMT1D68K-F maintains active product status. Selection of the DMT1D68K-F ensures access to current manufacturing inventory and ongoing supplier support.

Compliance Advantage: The DMT1D68K-F achieves ROHS3 compliance, whereas the original DMT1D68K is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the DMT1D68K-F provides compliance alignment without electrical or mechanical design modification.

Packaging Availability: The DMT1D68K-F is available in bulk packaging, supporting higher-volume procurement requirements. Both parts maintain identical lead spacing (0.394" / 10.00mm) and physical dimensions, ensuring direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can the DMT1D68K-F be used as a direct replacement for the DMT1D68K?
