TAC105K035P02-F Equivalent & Substitute Parts

Part Overview

The TAC105K035P02-F is a 1 µF molded tantalum capacitor rated at 35 V with ±10% tolerance, manufactured by Cornell Dubilier Electronics (CDE) in axial through-hole configuration. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing design support and procurement continuity. Active alternatives from Vishay Sprague and KEMET provide direct functional equivalence while maintaining identical electrical specifications and physical dimensions.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical and mechanical compatibility with the TAC105K035P02-F:

Direct Equivalents (Same Specifications): Parts maintaining identical capacitance (1 µF), voltage rating (35 V), tolerance (±10%), physical dimensions (0.110" Dia x 0.290" L), and operating temperature range (-55°C ~ 125°C). These parts are interchangeable without circuit redesign:

• 173D105X9035VE3 (Vishay Sprague)
• 173D105X9035VWE3 (Vishay Sprague)
• T322B105K035AT (KEMET)

Upgrade Alternatives: Parts that exceed the original specifications in tolerance or voltage rating while maintaining the same capacitance, physical dimensions, and operating temperature range. These provide enhanced performance characteristics:

• 173D105X5035VE3 (Vishay Sprague) – Tighter tolerance (±5% vs ±10%)
• 173D105X9050VWE3 (Vishay Sprague) – Higher voltage rating (50 V vs 35 V)
• 173D105X5050VWE3 (Vishay Sprague) – Higher voltage rating (50 V) with tighter tolerance (±5%)
• T322B105K050AT (KEMET) – Higher voltage rating (50 V vs 35 V)

Substitution eligibility is determined by: capacitance value, voltage rating (equal or higher), tolerance (equal or tighter), physical dimensions, mounting type, and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No Circuit Modification Required):

Select from the direct equivalent group when the original 35 V rating and ±10% tolerance are specified in the circuit design:

• 173D105X9035VWE3 (Vishay Sprague TANTALEX™ 173D series) – Highest inventory availability (13,346 pcs), active product status, ROHS3 compliant, REACH unaffected
• 173D105X9035VE3 (Vishay Sprague TANTALEX™ 173D series) – Active product status, ROHS3 compliant, REACH unaffected
• T322B105K035AT (KEMET T322 series) – Active product status, ROHS3 compliant, REACH unaffected, 8Ω ESR specification

For Enhanced Performance (Circuit Redesign Not Required):

Upgrade alternatives provide superior specifications while maintaining physical and thermal compatibility:

• 173D105X5035VE3 – Tighter ±5% tolerance at 35 V rating for applications requiring improved capacitance accuracy
• 173D105X9050VWE3 – Higher 50 V rating for circuits operating at lower voltage margins or requiring additional safety margin
• 173D105X5050VWE3 – Combined benefits of higher 50 V rating and ±5% tolerance for demanding applications
• T322B105K050AT – Higher 50 V rating with 8Ω ESR specification

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

Frequently Asked Questions (FAQ)

Q: Can I use 173D105X9035VWE3 as a direct replacement for TAC105K035P02-F?

A: Yes. The 173D105X9035VWE3 is a direct equivalent with identical capacitance (1 µF), voltage rating (35 V), tolerance (±10%), physical dimensions (0.110" Dia x 0.290" L), and operating temperature range (-55°C ~ 125°C). No circuit modification is required.

Q: What is the difference between 173D105X9035VE3 and 173D105X9035VWE3?

A: Both parts are electrically and mechanically identical (1 µF, 35 V, ±10%, axial, same dimensions). The difference is packaging: 173D105X9035VE3 is supplied in Cut Tape (CT), while 173D105X9035VWE3 is supplied in Cut Tape (CT) with higher inventory availability. Selection depends on procurement and assembly requirements.

Q: Can I substitute a 50 V rated part (173D105X9050VWE3) for the 35 V original?

A: Yes. A higher voltage rating (50 V) is a valid upgrade substitute for a 35 V application. The circuit will operate safely with the higher-rated component. This substitution is appropriate when the original 35 V part is unavailable or when additional voltage margin is desired.

Q: What does ±5% tolerance mean compared to ±10%?

A: Tolerance specifies the allowable deviation from the nominal capacitance value. ±5% tolerance (173D105X5035VE3) provides tighter capacitance accuracy than ±10% tolerance (TAC105K035P02-F). A ±5% part is a valid upgrade substitute for a ±10% application, as it meets or exceeds the original specification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the compliance status of the original TAC105K035P02-F.

Q: What is the significance of the KEMET T322B105K035AT having 8Ω ESR?

A: ESR (Equivalent Series Resistance) of 8Ω is a specified electrical characteristic of the KEMET T322 series. This value is provided for applications where ESR performance is a design consideration. The original TAC105K035P02-F does not specify ESR, so this parameter does not affect substitution eligibility.

Q: Can I use T322B105K035AT in place of the Vishay 173D105X9035VE3?

A: Yes. Both parts are direct equivalents with identical capacitance (1 µF), voltage rating (35 V), tolerance (±10%), physical dimensions, and operating temperature range. Selection between manufacturers depends on procurement availability, lead time, and packaging requirements.

Q: Which substitute part has the highest inventory availability?

A: 173D105X9035VWE3 (Vishay Sprague) has the highest inventory with 13,346 pcs in stock, followed by 173D105X9050VWE3 with 4,240 pcs.
