Key Parameters

Substitute Part Grouping Explanation

Substitution of the DSF100J103 is determined by strict equivalence across the following parameters:

Critical Electrical Parameters:

• Capacitance value: 10000 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating - DC: 100V (minimum requirement; higher ratings acceptable)
• Dielectric Material: Polyester, Metallized (functional equivalence)

Critical Mechanical Parameters:

• 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)

Compliance Parameters:

• RoHS3 Compliance (required for modern applications)
• REACH Unaffected status (required for regulatory compliance)

The identified substitute parts meet all critical electrical and mechanical parameters while offering active product status and enhanced operating temperature ranges.

Engineering Selection Recommendations

168103J100A-F (Cornell Dubilier Electronics - Direct Manufacturer Substitute)

The 168103J100A-F represents a direct manufacturer equivalent from Cornell Dubilier Electronics. This part maintains identical electrical specifications (10000 pF, ±5%, 100V DC) and mechanical compatibility (radial through-hole, 5.00mm lead spacing). The substitute offers an extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 85°C) and active product status. Physical dimensions are reduced (7.20mm x 2.50mm versus 7.50mm x 3.20mm), providing improved board space efficiency. ROHS3 compliance and REACH unaffected status ensure regulatory alignment with current manufacturing standards.

R82EC2100AA50J (KEMET - Cross-Manufacturer Substitute)

The R82EC2100AA50J from KEMET provides electrical equivalence with identical capacitance, tolerance, and DC voltage rating. This part features polyethylene terephthalate (PET) metallized-stacked dielectric construction and maintains mechanical compatibility through identical lead spacing and radial through-hole mounting. The operating temperature range (-55°C ~ 105°C) exceeds the original specification. AEC-Q200 automotive qualification and ROHS3 compliance support applications requiring automotive-grade reliability. Physical dimensions match the 168103J100A-F (7.20mm x 2.50mm), enabling direct board-level substitution.

Both substitute parts satisfy all critical electrical and mechanical parameters required for functional equivalence. Selection between alternatives depends on supply chain availability, cost considerations, and application-specific requirements for automotive qualification or extended temperature performance.

Frequently Asked Questions (FAQ)

Q: Can the 168103J100A-F be used as a direct replacement for the DSF100J103?

A: Yes. The 168103J100A-F meets all critical electrical parameters (10000 pF, ±5%, 100V DC) and mechanical requirements (radial through-hole, 5.00mm lead spacing, PC pins). Physical dimensions are smaller, but the component occupies less board space without affecting electrical function. Both parts are ROHS3 compliant and REACH unaffected.

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

A: Both 168103J100A-F and R82EC2100AA50J provide electrical equivalence. The primary differences are manufacturer (CDE versus KEMET), dielectric material specification (polyester metallized versus polyester PET metallized-stacked), and automotive qualification (R82EC2100AA50J carries AEC-Q200 rating). Operating temperature ranges differ slightly (-55°C ~ 125°C for CDE versus -55°C ~ 105°C for KEMET). Physical dimensions are identical between the two substitutes.

Q: Are the physical dimensions of the substitute parts compatible with the original PCB layout?

A: The substitute parts feature reduced physical dimensions (7.20mm x 2.50mm versus 7.50mm x 3.20mm for the original). Lead spacing remains identical at 5.00mm, ensuring through-hole compatibility. The reduced height (6.50mm to 6.60mm versus 8.00mm) provides additional clearance. PCB layouts designed for the DSF100J103 accommodate these smaller substitutes without modification.

Q: Do the substitute parts maintain the same moisture sensitivity level?

A: The 168103J100A-F maintains MSL 1 (Unlimited) classification, identical to the original. The R82EC2100AA50J lists MSL as Not Applicable, indicating no moisture sensitivity restrictions. Both substitutes are suitable for standard handling and storage procedures.

Q: Which substitute part should be selected for automotive applications?

A: The R82EC2100AA50J is qualified to AEC-Q200 automotive standards and is designated for automotive applications. The 168103J100A-F does not carry automotive qualification but remains suitable for general-purpose applications. Application requirements determine the appropriate selection.

Q: Are both substitute parts available in equivalent quantities?

A: Inventory levels differ between substitutes. The 168103J100A-F has 6528 pieces in stock, while the R82EC2100AA50J has 32350 pieces available. Supply chain requirements may influence part selection based on project timelines and volume needs.
