TARS335K035 Equivalent & Substitute Parts

Part Overview

The TARS335K035 is a 3.3 µF molded tantalum capacitor rated for 35 V with axial through-hole mounting, manufactured by KYOCERA AVX. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. Substitute parts must maintain identical electrical specifications (capacitance, voltage rating, tolerance) and compatible physical dimensions to ensure direct replacement in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TARS335K035 are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Capacitance: 3.3 µF (exact match required)
• Voltage Rating: 35 V (exact match required)
• Tolerance: ±10% (exact match required)
• Type: Molded Tantalum (exact match required)
• Mounting Type: Through Hole Axial (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

Compatible Variation Parameters:

• ESR: Specifications provided where available; absence of ESR data does not disqualify a substitute
• Physical Dimensions: Minor variations within 0.180" Dia x 0.345" L (4.57mm x 8.76mm) are acceptable for axial through-hole mounting
• Packaging Format: Tape & Reel (TR) or Bulk packaging formats are interchangeable for component-level substitution
• RoHS Compliance: Both RoHS non-compliant and ROHS3 compliant variants are functionally equivalent

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts meet the core electrical and mechanical requirements for direct replacement of the TARS335K035. Selection among available substitutes should be based on the following criteria:

For RoHS non-compliant applications: 173D335X9035W (Vishay Sprague) or T322C335K035AS (KEMET) are suitable. Both maintain the original RoHS non-compliant status and provide active product support.

For ROHS3 compliant applications: 173D335X9035WE3, 173D335X9035WWE3 (Vishay Sprague), or T322C335K035AT (KEMET) are suitable. These parts meet ROHS3 compliance requirements while maintaining all electrical specifications.

For ESR-critical applications: T322C335K035AS and T322C335K035AT (KEMET) specify 4 Ohm ESR, matching the original TARS335K035. Vishay Sprague 173D series parts do not provide ESR specifications in available documentation.

For packaging considerations: Vishay Sprague parts are supplied in Tape & Reel format; KEMET parts are supplied in Bulk format. Packaging selection depends on procurement and assembly requirements.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with different physical dimensions? A: Substitute parts with dimensions of 0.180" Dia x 0.345" L (4.57mm x 8.76mm) are compatible with the original 0.169" Dia x 0.339" L (4.30mm x 8.60mm) specification for through-hole axial mounting. The slight dimensional increase does not affect electrical performance or board-level compatibility.

Q: Are Vishay Sprague and KEMET parts interchangeable? A: Yes. Both manufacturers' parts listed meet identical electrical specifications (3.3 µF, 35 V, ±10% tolerance, -55°C ~ 125°C operating range) and axial through-hole mounting requirements. Selection between manufacturers depends on availability, packaging format preference, and RoHS compliance requirements.

Q: What is the difference between RoHS non-compliant and ROHS3 compliant variants? A: ROHS3 compliant parts meet Restriction of Hazardous Substances Directive 3 requirements and are suitable for applications with environmental or regulatory compliance mandates. RoHS non-compliant parts are suitable for legacy systems or applications without such requirements. Both variants are electrically and mechanically equivalent.

Q: Does the absence of ESR specification in Vishay Sprague parts affect compatibility? A: ESR is not a disqualifying factor for substitution. KEMET T322 series parts specify 4 Ohm ESR, matching the original TARS335K035. Vishay Sprague 173D series parts do not provide ESR data in available documentation but are functionally equivalent for general-purpose applications. For ESR-critical circuit designs, KEMET parts are the preferred choice.

Q: Can I mix packaging formats (Tape & Reel vs. Bulk) in production? A: Yes. Packaging format is a procurement and assembly consideration only. Tape & Reel and Bulk formats contain identical components and are interchangeable at the component level.

Q: Is the TARS335K035 still available? A: The TARS335K035 is classified as obsolete. Current inventory of 856 pieces is available, but long-term availability is not assured. Migration to active substitute parts (173D335X9035WE3, 173D335X9035WWE3, T322C335K035AT) is recommended for new designs and ongoing production.
