Engineering Selection Recommendations

Primary Substitute: 168682K100A-F

The 168682K100A-F is the qualified equivalent for DLR1D68K-F replacement. Selection rationale is based on the following factors:

Electrical Equivalence: All critical electrical parameters match exactly: 6800 pF capacitance, ±10% tolerance, 100V DC rating, and 63V AC rating. The polyester dielectric material family is maintained, with metallized construction providing enhanced performance characteristics.

Compliance Status: Both components maintain ROHS3 Compliant and REACH Unaffected certifications, ensuring regulatory continuity in manufacturing and supply chain operations.

Product Availability: The substitute part carries Active product status with 1030 units in current inventory, providing reliable procurement continuity compared to the Obsolete status of the original part.

Temperature Performance: The substitute component operates across -55°C to 125°C, exceeding the original part's -40°C to 85°C range. This extended capability provides additional design margin for thermal applications.

Physical Consideration: Lead spacing differs between parts (3.50mm versus 5.00mm). Circuit board layout verification is required to confirm mechanical compatibility with existing PCB hole patterns and trace routing.

Frequently Asked Questions (FAQ)

Q: Can 168682K100A-F be used as a direct replacement for DLR1D68K-F?

A: Electrical substitution is valid based on matching capacitance, tolerance, voltage rating, and dielectric material. Physical board compatibility requires verification of lead spacing (3.50mm original versus 5.00mm substitute) against existing PCB hole patterns.

Q: What is the significance of the metallized polyester construction in the substitute part?

A: Metallized polyester construction in the 168682K100A-F represents an enhanced dielectric configuration within the polyester film capacitor family. This maintains electrical equivalence while providing improved performance characteristics compared to standard polyester film construction.

Q: Why is the operating temperature range different between the two parts?

A: The substitute part 168682K100A-F operates across -55°C to 125°C versus the original -40°C to 85°C range. This extended temperature capability is a characteristic of the 168 series design and does not affect substitution validity for applications within the original part's temperature specification.

Q: Are there compliance differences between the parts?

A: No. Both DLR1D68K-F and 168682K100A-F maintain identical ROHS3 Compliant and REACH Unaffected certifications, ensuring regulatory equivalence for manufacturing and supply chain requirements.

Q: What is the primary reason for substitution?

A: The DLR1D68K-F is classified as Obsolete. The 168682K100A-F is an Active product with current manufacturing and inventory support, providing procurement continuity for ongoing production and field service applications.

Q: Does lead spacing affect circuit functionality?

A: Lead spacing affects only physical board layout and component placement. Electrical circuit function remains unchanged. PCB redesign or adapter solutions may be required if existing hole patterns cannot accommodate the 5.00mm lead spacing of the substitute part.
