The substitute part 199D476X9035F6V1E3 (Vishay Sprague TANTALEX™ 199D series) meets all specified electrical and mechanical parameters. The component is currently in active production status, ensuring long-term availability and supply chain stability.

Parameter Comparison

Engineering Selection Recommendations

The 199D476X9035F6V1E3 is a direct functional equivalent for replacement applications. Both components are ROHS3 compliant and share identical electrical specifications. The substitute part holds active product status, ensuring continued availability and support through the manufacturing lifecycle. The Vishay Sprague component provides documented lifetime performance data (1000 Hrs @ 85°C), offering additional reliability transparency compared to the original CDE part.

Mechanical fit considerations require verification during PCB design transition. The substitute exhibits a smaller diameter body (0.378" vs 0.440") and greater maximum height (0.748" vs 0.680"). Lead spacing remains identical at 0.200", maintaining footprint compatibility. Clearance validation is necessary in confined applications or assemblies with tight component spacing constraints.

Frequently Asked Questions (FAQ)

Q: Are the electrical characteristics identical between TDL476K035M1F-F and 199D476X9035F6V1E3? A: Yes. Both components share identical capacitance (47 µF), tolerance (±10%), voltage rating (35 V), and operating temperature range (-55°C ~ 125°C). Both are conformal coated tantalum capacitors with radial through-hole configuration.

Q: What physical differences exist between these parts? A: The substitute part exhibits a smaller body diameter (0.378" vs 0.440") but greater maximum height (0.748" vs 0.680"). Lead spacing and pitch remain unchanged at 0.200" (5.08mm). Physical clearance verification is required for high-density layouts.

Q: Can 199D476X9035F6V1E3 replace TDL476K035M1F-F in existing designs? A: Electrical substitution is direct due to matched specifications. PCB layout modification may be necessary to accommodate the dimensional differences. The identical lead spacing allows direct footprint usage if height and width constraints are satisfied.

Q: What compliance certifications apply to both parts? A: Both components meet ROHS3 compliance standards. The 199D476X9035F6V1E3 carries REACH Unaffected status. Both are classified under ECCN EAR99 and HTSUS 8532.21.0040.

Q: Why is the CDE part listed as obsolete? A: Cornell Dubilier Electronics has discontinued the TDL series. The Vishay Sprague 199D series provides active, ongoing production with established supply chain availability.
