TAC475K050P06-F Equivalent & Substitute Parts

Part Overview

The TAC475K050P06-F is a 4.7 µF molded tantalum capacitor rated for 50 V operation in axial through-hole configuration. Manufactured by Cornell Dubilier Electronics (CDE), this part operates across the industrial temperature range of -55°C to 125°C with ±10% capacitance tolerance and ROHS3 compliance. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing board repairs, refurbishment, and legacy system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TAC475K050P06-F is determined by strict equivalence of the following parameters: capacitance (4.7 µF), voltage rating (50 V), tolerance (±10%), type (molded tantalum), mounting method (through hole axial), and physical dimensions (0.180" Dia × 0.420" L). All identified substitute parts maintain these core electrical and mechanical specifications, ensuring functional and physical compatibility within legacy circuit designs.

The substitute parts are categorized as follows:

Direct Substitutes (Active): Parts matching all key parameters with equivalent electrical performance across the operating temperature range.

Upgraded Substitute: Parts exceeding original specifications in tolerance (±5% vs. ±10%), providing enhanced precision while maintaining full backward compatibility with the original design intent.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are manufactured by active, established suppliers and maintain ROHS3 compliance, ensuring compatibility with current manufacturing and environmental standards. The TAC475K050P06-F, being obsolete, necessitates selection from the active substitute options.

For direct replacement applications requiring equivalent performance: 173D475X9050XE3, 173D475X9050XWE3, and T322D475K050AT provide specification-identical substitution across all electrical and mechanical parameters.

For applications where tolerance precision is beneficial: 173D475X5050XWE3 offers ±5% tolerance, representing an upgrade specification while maintaining full functional compatibility.

Packaging format selection should align with procurement requirements: Tape & Box (173D475X9050XE3) for smaller quantities, Tape & Reel (173D475X9050XWE3, 173D475X5050XWE3) for manufacturing automation and bulk operations, or Bulk (T322D475K050AT) for consolidated ordering.

Frequently Asked Questions (FAQ)

Q: Are these parts drop-in replacements for the TAC475K050P06-F? A: Yes. The substitute parts maintain identical capacitance (4.7 µF), voltage rating (50 V), type (molded tantalum), axial through-hole mounting, and physical dimensions (0.180" Dia × 0.420" L), enabling direct substitution in PCB footprints and circuit designs without modification.

Q: What is the difference between the direct substitutes and the 173D475X5050XWE3? A: The 173D475X5050XWE3 has ±5% tolerance compared to the ±10% tolerance of other substitutes. This provides tighter capacitance accuracy and is suitable for applications requiring precision filtering or timing circuits, while remaining fully backward compatible with the original specification.

Q: Does packaging format affect electrical performance? A: No. The Tape & Box (TB), Tape & Reel (TR), and Bulk packaging formats contain electrically identical components. Selection should be based on assembly process requirements and quantity needs. Tape & Reel format is preferred for automated surface-mount and through-hole assembly lines, while Bulk and Tape & Box formats support lower-volume or manual assembly operations.

Q: Is the Moisture Sensitivity Level difference significant? A: The MSL 1 classification of the original TAC475K050P06-F (Unlimited) and the Not Applicable designation for substitute parts reflect differences in manufacturer classification methodologies. Molded tantalum capacitors in both classifications are suitable for standard PCB assembly, storage, and handling without specialized moisture-control requirements.

Q: Can T322D475K050AT be used if ESR specification is critical? A: Yes. The T322D475K050AT provides a specified ESR of 2.5 Ω. If ESR is a design requirement, this part explicitly documents the value. The other substitutes do not provide ESR specifications but are functionally equivalent for general-purpose tantalum capacitor applications.
