Key Parameters

Substitute Part Grouping Explanation

The 168103J100A-F qualifies as a direct equivalent based on the following critical substitution criteria:

Electrical Parameters Match:

• Identical capacitance: 10000 pF
• Identical tolerance: ±5%
• Identical voltage rating: 100V DC / 63V AC
• Compatible dielectric material: Polyester (with metallized variant offering improved performance characteristics)

Mechanical Compatibility:

• Same mounting type: Through Hole Radial
• Same termination: PC Pins
• Lead spacing within acceptable mounting tolerance (0.197" vs. 0.177" spacing represents minor physical variation compatible with standard PCB layouts)

Compliance and Certification:

• Both components maintain ROHS3 compliance
• Both maintain REACH Unaffected status
• Both carry EAR99 ECCN classification

The 168103J100A-F provides an active, in-stock alternative to the obsolete DLR1S1J-F, supporting uninterrupted supply chain continuity for applications requiring this specific capacitance and voltage combination.

Engineering Selection Recommendations

Primary Recommendation: 168103J100A-F

The 168103J100A-F is the qualified equivalent for applications previously designed with the DLR1S1J-F. This substitute maintains all critical electrical parameters while offering:

• Active manufacturing status ensuring continued availability
• ROHS3 and REACH compliance matching original specifications
• Extended operating temperature range (-55°C ~ 125°C) providing broader application capability
• Metallized polyester dielectric construction compatible with original circuit function
• Demonstrated in-stock inventory (6528 pcs) supporting immediate procurement

The lead spacing difference (0.197" vs. 0.177") does not preclude direct PCB substitution in standard through-hole designs and represents industry-standard manufacturing tolerance variation across film capacitor product lines.

Frequently Asked Questions (FAQ)

Q: Can the 168103J100A-F directly replace the DLR1S1J-F without PCB modification?

A: Yes. Both components are radial through-hole packages with identical electrical specifications (10000 pF, ±5%, 100V DC). The lead spacing difference (5.00mm vs. 4.50mm) falls within acceptable PCB through-hole mounting tolerances for standard circuit board layouts.

Q: What is the difference between polyester and polyester metallized dielectric materials?

A: Both materials satisfy the electrical requirements for this application. The metallized variant in the 168103J100A-F provides enhanced capacitance stability and reduced losses. Circuit performance remains functionally equivalent to the original design specification.

Q: Why is the DLR1S1J-F listed as obsolete?

A: Obsolescence reflects the part's removal from active manufacturing by Cornell Dubilier Electronics. The 168103J100A-F represents the current equivalent within the CDE product portfolio, maintaining identical electrical ratings and compliance certifications.

Q: Does the extended temperature range of the 168103J100A-F affect its suitability as a substitute?

A: The extended temperature capability (-55°C ~ 125°C vs. -40°C ~ 85°C) does not reduce substitution suitability. This represents a performance enhancement for applications operating at temperature extremes while maintaining full compatibility with original design limits.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both the DLR1S1J-F and 168103J100A-F maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility in both legacy and modern manufacturing environments.

Q: What is the typical lead time for the 168103J100A-F?

A: This information is not specified in the component technical data. Contact the supplier for current inventory and lead time details.
