Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TAC474K035P01-F are categorized based on strict electrical and mechanical parameter matching:

Direct Substitutes (Identical Electrical & Mechanical Parameters): Direct substitutes maintain all critical parameters: 0.47 µF capacitance, ±10% tolerance, 35 V voltage rating, axial through-hole mounting, and identical physical dimensions (0.095" Dia x 0.260" L). These parts are interchangeable without circuit redesign. Differences exist only in packaging format (Tape & Box, Cut Tape, or Bulk) and manufacturer (Vishay Sprague TANTALEX™ 173D series or KEMET T322 series).

Upgrade Substitutes (Enhanced Specifications): Upgrade substitutes provide improved performance through tighter tolerance (±5% instead of ±10%) or higher voltage rating (50 V instead of 35 V). These parts are electrically compatible but offer enhanced reliability margins. Physical dimensions may increase with higher voltage ratings.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No Circuit Modification Required):

Select from active-status direct substitutes when the original TAC474K035P01-F is unavailable:

• 173D474X9035UWE3 (Vishay Sprague TANTALEX™ 173D): Highest inventory availability (2699 Pcs) in Cut Tape packaging. Suitable for high-volume production and automated assembly.
• 173D474X9035UE3 (Vishay Sprague TANTALEX™ 173D): Available in Tape & Box packaging (613 Pcs). Appropriate for lower-volume applications.
• T322A474K035AT (KEMET T322): Available in Bulk packaging (1136 Pcs). Specified ESR of 13 Ohm provides documented performance characteristics.

All three direct substitutes are ROHS3 compliant and maintain identical electrical and mechanical specifications.

For Enhanced Reliability (Circuit Redesign Not Required):

Upgrade substitutes provide improved performance margins while maintaining backward compatibility:

• 173D474X5035UE3 (Vishay Sprague): Tighter ±5% tolerance at 35 V rating. Identical physical dimensions. Suitable when tolerance-sensitive applications require improved capacitance stability.
• 173D474X9050VWE3 (Vishay Sprague) or T322B474K050AT (KEMET): Higher 50 V rating with same 0.47 µF capacitance. Larger physical dimensions (0.110" Dia x 0.290" L). Provides increased voltage margin for circuits operating near the 35 V limit.

All substitute parts maintain the -55°C to 125°C operating temperature range and ROHS3 compliance of the original component.

Frequently Asked Questions (FAQ)

Q: Can I use 173D474X9035UWE3 as a direct replacement for TAC474K035P01-F?

A: Yes. The 173D474X9035UWE3 is a direct substitute with identical electrical parameters (0.47 µF, ±10%, 35 V) and physical dimensions (0.095" Dia x 0.260" L). The only difference is packaging format (Cut Tape versus the original format). No circuit modification is required.

Q: What is the difference between the Vishay Sprague and KEMET substitutes?

A: Both manufacturers provide direct substitutes with identical capacitance, tolerance, and voltage ratings. The KEMET T322A474K035AT specifies an ESR of 13 Ohm, providing documented equivalent series resistance. Vishay Sprague parts do not specify ESR in the provided data. Packaging differs: KEMET offers Bulk format, while Vishay Sprague offers Tape & Box or Cut Tape options.

Q: Can I use the 50 V rated parts (173D474X9050VWE3 or T322B474K050AT) in place of the 35 V original?

A: Yes, electrically these are compatible upgrades. The 50 V rating provides additional voltage margin. However, physical dimensions increase (0.110" Dia x 0.290" L versus 0.095" Dia x 0.260" L). Verify that the larger size fits within the available PCB space before substitution.

Q: What advantage does the ±5% tolerance version (173D474X5035UE3) provide?

A: The ±5% tolerance version maintains tighter capacitance accuracy compared to the ±10% original specification. This is beneficial in applications where capacitance value stability directly affects circuit performance. Physical dimensions remain identical to the original.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the compliance status of the original TAC474K035P01-F.

Q: Which substitute has the highest inventory availability?

A: The 173D474X9035UWE3 (Vishay Sprague TANTALEX™ 173D in Cut Tape packaging) has the highest inventory with 2699 Pcs available.
