DSF100J683 Film Capacitor Equivalent & Substitute Parts

Part Overview

The DSF100J683 is a 0.068 µF film capacitor rated for 100V DC, manufactured by Cornell Dubilier Electronics (CDE) in the DSF series. This component features a polyester metallized-stacked dielectric with radial through-hole mounting, designed for general-purpose applications across an operating temperature range of -40°C to 85°C.

The DSF100J683 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DSF100J683 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must align for substitution:

Critical Matching Parameters:

• Capacitance: 0.068 µF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating - DC: 100V (minimum requirement; higher ratings acceptable)
• Dielectric Material: Polyester, Metallized (functional equivalence)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Lead Spacing: 0.197" (5.00mm) (exact match required)
• Termination: PC Pins (exact match required)

Acceptable Variation Parameters:

• Operating Temperature Range: Substitute parts may exceed the original range
• Physical Dimensions: Minor variations acceptable if lead spacing and mounting type remain unchanged
• Voltage Rating - AC: Presence of AC rating in substitute does not disqualify compatibility
• Product Status: Active parts are preferred over obsolete parts for ongoing supply

Two substitute parts meet these criteria and are listed below.

Engineering Selection Recommendations

168683J100H-F (Cornell Dubilier Electronics - Direct Manufacturer Substitute)

This part is manufactured by the same original equipment manufacturer (CDE) and represents a direct successor within the CDE product line. It maintains identical electrical specifications (0.068 µF, ±5%, 100V DC) and mechanical compatibility (radial, 5.00mm lead spacing, PC pins). The operating temperature range is extended (-55°C ~ 125°C versus -40°C ~ 85°C), providing enhanced thermal performance. Physical dimensions are reduced, resulting in a smaller footprint while maintaining full electrical equivalence. Product status is active, ensuring long-term availability. ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1) are maintained.

R82EC2680AA60J (KEMET - Cross-Manufacturer Substitute)

This part is manufactured by KEMET, a major capacitor supplier, and provides functional equivalence across all critical electrical parameters. Capacitance, tolerance, and DC voltage rating are identical to the original part. The dielectric material is polyester with PET metallization in a stacked configuration, functionally equivalent to the original polyester metallized design. Operating temperature range is extended (-55°C ~ 105°C), and the part carries AEC-Q200 automotive qualification. Physical dimensions match the 168683J100H-F substitute. Product status is active with robust inventory availability (71,453 units in stock). ROHS3 compliance is maintained.

Both substitutes are electrically and mechanically compatible with the DSF100J683. Selection between them depends on supply chain preference, inventory availability, and any application-specific requirements related to automotive qualification (R82EC2680AA60J carries AEC-Q200 rating).

Frequently Asked Questions (FAQ)

Q: Can the 168683J100H-F be used as a direct replacement for the DSF100J683?

A: Yes. The 168683J100H-F meets all critical electrical and mechanical compatibility criteria. It maintains identical capacitance (0.068 µF), tolerance (±5%), DC voltage rating (100V), mounting type (through-hole radial), lead spacing (5.00mm), and termination (PC pins). The extended operating temperature range and reduced physical dimensions present no compatibility issues for standard applications.

Q: What is the difference between the two substitute parts?

A: Both substitutes are electrically equivalent. The primary differences are manufacturer (CDE versus KEMET) and dielectric composition (polyester metallized versus polyester PET metallized). The KEMET part (R82EC2680AA60J) carries AEC-Q200 automotive qualification, making it suitable for automotive applications. Physical dimensions are identical between the two substitutes but smaller than the original DSF100J683.

Q: Will the smaller physical dimensions of the substitute parts affect PCB layout?

A: The substitute parts (168683J100H-F and R82EC2680AA60J) are physically smaller than the original DSF100J683 but maintain the same lead spacing (5.00mm). PCB footprints designed for the original part will accommodate the substitutes. The reduced height may provide additional clearance in space-constrained designs.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both 168683J100H-F and R82EC2680AA60J are ROHS3 compliant, matching the compliance status of the original DSF100J683.

Q: Which substitute part should be selected for new designs?

A: Both parts are suitable for new designs. The 168683J100H-F is recommended for direct CDE product line continuity. The R82EC2680AA60J is recommended for applications requiring automotive qualification (AEC-Q200) or when KEMET supply chain preference exists.

Q: Can these substitutes be used in AC applications?

A: The substitute parts include AC voltage ratings (63V AC), whereas the original DSF100J683 does not specify an AC rating. For AC applications, the 63V AC rating of the substitutes applies. Verify that the AC voltage in the application does not exceed 63V.
