DPP1S68K Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPP1S68K is a 0.068 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) from the DPP series. This radial polypropylene metallized film capacitor is rated for 100V DC operation with ±10% tolerance and features low ESR characteristics suitable for high-frequency and switching applications. The DPP1S68K is classified as obsolete, necessitating identification of active equivalent parts to ensure design continuity and procurement availability for new production and maintenance applications.

Substitute Part Grouping Explanation

Substitution of the DPP1S68K is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Parameters (Non-negotiable):

• Capacitance value: 0.068 µF
• Tolerance: ±10%
• Voltage rating (DC): 100V minimum
• Voltage rating (AC): 70V minimum
• Dielectric material: Polypropylene (PP), Metallized
• Operating temperature range: -55°C to +105°C minimum

Mechanical Parameters (Non-negotiable):

• Mounting type: Through Hole
• Package type: Radial
• Physical dimensions: 20.00mm L × 9.50mm W
• Lead spacing: 15.00mm
• Termination: PC Pins

Application Compatibility:

• High-frequency and switching circuit applications
• Low ESR performance requirement

The DPP1S68K-F meets all specified electrical and mechanical parameters and is classified as an active product, making it a direct functional equivalent suitable for replacement in all applications where the DPP1S68K was originally specified.

Engineering Selection Recommendations

The DPP1S68K-F is the direct equivalent replacement for the obsolete DPP1S68K. Selection of the DPP1S68K-F is based on the following factors:

Product Status: The DPP1S68K-F is classified as an active product, ensuring long-term availability and supply chain continuity. The DPP1S68K is obsolete and subject to discontinuation.

Regulatory Compliance: The DPP1S68K-F is ROHS3 compliant, meeting current environmental and hazardous substance restrictions. The DPP1S68K is RoHS non-compliant and does not meet modern regulatory requirements for new designs and production.

Electrical and Mechanical Equivalence: All electrical parameters (capacitance, voltage ratings, dielectric material, temperature range) and mechanical parameters (dimensions, lead spacing, termination type, mounting configuration) are identical between the two parts.

Application Compatibility: Both parts are suitable for high-frequency and switching applications with identical low ESR performance characteristics. The DPP1S68K-F maintains full functional compatibility with all original DPP1S68K circuit designs.

For new designs, production runs, and maintenance applications requiring the DPP1S68K specification, the DPP1S68K-F is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the DPP1S68K-F be used as a direct replacement for the DPP1S68K in existing circuit designs?

A: Yes. The DPP1S68K-F is electrically and mechanically identical to the DPP1S68K. All electrical parameters (0.068 µF capacitance, 100V DC rating, ±10% tolerance, polypropylene dielectric) and mechanical parameters (radial package, 15.00mm lead spacing, 20.00mm × 9.50mm dimensions) are equivalent. The DPP1S68K-F is a direct functional equivalent suitable for all applications where the DPP1S68K was originally specified.

Q: What is the primary difference between the DPP1S68K and DPP1S68K-F?

A: The primary differences are product status and regulatory compliance. The DPP1S68K is obsolete and RoHS non-compliant. The DPP1S68K-F is an active product and ROHS3 compliant, meeting current environmental regulations and ensuring ongoing supply availability.

Q: Are the physical dimensions and lead spacing identical?

A: Yes. Both parts have identical physical dimensions of 20.00mm length × 9.50mm width, maximum seated height of 19.50mm, and lead spacing of 15.00mm. The DPP1S68K-F will fit existing PCB layouts designed for the DPP1S68K without modification.

Q: Can the DPP1S68K-F be used in high-frequency and switching applications?

A: Yes. The DPP1S68K-F is specified for high-frequency and switching applications and features low ESR characteristics identical to the DPP1S68K, making it suitable for these application categories.

Q: Is the DPP1S68K-F suitable for new product designs?

A: Yes. The DPP1S68K-F is an active product with ROHS3 compliance, making it the appropriate choice for new designs. The obsolete DPP1S68K should not be specified for new products.

Q: What is the operating temperature range for the DPP1S68K-F?

A: The operating temperature range is -55°C to +105°C, identical to the DPP1S68K. This range supports operation across industrial and commercial temperature environments.
