Substitute Part Grouping Explanation

Substitute parts for the T322D476K006AS are classified into two categories based on allowed electrical and mechanical parameters:

Direct Equivalent Substitutes maintain identical electrical specifications (47 µF, ±10% tolerance, 6 V rating, 2 Ohm ESR) and mechanical dimensions. These parts are interchangeable at the circuit level with no design modifications required.

Upgrade Substitutes maintain the same capacitance value (47 µF) and tolerance (±10%), identical physical dimensions, and compatible mounting type, but feature an elevated voltage rating (10 V instead of 6 V) and reduced ESR (1.7 Ohm instead of 2 Ohm). These parts provide enhanced performance margins and are electrically compatible with circuits designed for the original 6 V specification.

The substitution logic is based strictly on the following parameters:

  • Capacitance value (47 µF)
  • Tolerance (±10%)
  • Package type (Axial, Through Hole)
  • Physical dimensions (0.180" Dia x 0.420" L)
  • Operating temperature range (-55°C ~ 125°C)
  • Series designation (T322)

Engineering Selection Recommendations

T322D476K006AT (Direct Equivalent) is selected when direct replacement with identical electrical performance is required. This part maintains all specifications of the main part number while offering ROHS3 compliance, providing regulatory advantage for applications subject to RoHS requirements. Inventory availability is 937 units.

T322D476K010AS (Upgrade) is selected when enhanced performance margins are beneficial within the circuit design constraints. The elevated 10 V voltage rating provides increased safety margin for circuits operating at or near 6 V nominal levels. The reduced ESR (1.7 Ohm versus 2 Ohm) improves transient response characteristics. This part is electrically backward-compatible with 6 V circuit designs. Inventory availability is 1034 units.

Selection between substitute parts is determined by compliance requirements and performance optimization needs. All three parts maintain identical physical dimensions, mounting type, and core electrical parameters (capacitance and tolerance), ensuring mechanical and functional interchangeability within the T322 series.

Frequently Asked Questions (FAQ)

Q: Can T322D476K006AT be used as a direct replacement for T322D476K006AS?

A: Yes. T322D476K006AT maintains identical electrical specifications (47 µF, ±10%, 6 V, 2 Ohm ESR) and physical dimensions. The primary difference is ROHS3 compliance status. No circuit modifications are required.

Q: Is T322D476K010AS compatible with circuits designed for T322D476K006AS?

A: Yes. T322D476K010AS is electrically compatible with 6 V circuit designs. The 10 V voltage rating is higher than the circuit requirement, and the reduced ESR (1.7 Ohm) provides improved performance. Physical dimensions are identical, enabling direct mechanical substitution.

Q: What are the key differences between the three parts?

A: T322D476K006AS and T322D476K006AT are electrically identical at 6 V, 2 Ohm ESR, differing only in RoHS compliance. T322D476K010AS differs by offering 10 V rating and 1.7 Ohm ESR while maintaining the same 47 µF capacitance and physical form factor.

Q: Are all three parts in the same physical package?

A: Yes. All three parts share identical dimensions (0.180" Dia x 0.420" L / 4.57mm x 10.67mm), axial package type, and through-hole mounting configuration. They are mechanically interchangeable.

Q: Which part should be selected for new designs?

A: Selection depends on compliance and performance requirements. For RoHS3-compliant applications, T322D476K006AT is appropriate. For applications benefiting from higher voltage margin and lower ESR, T322D476K010AS is suitable. For legacy designs without compliance constraints, T322D476K006AS remains valid.

Q: Do all parts operate across the same temperature range?

A: Yes. All three parts operate across -55°C to 125°C, maintaining consistent performance across the full temperature spectrum.
