TARR685M015 Equivalent & Substitute Parts

Part Overview

The TARR685M015 is a 6.8 µF molded tantalum capacitor rated at 15 V with ±20% tolerance, manufactured by KYOCERA AVX in axial through-hole configuration. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing production and maintenance applications. Substitute parts must maintain electrical equivalence across capacitance, voltage rating, tolerance, and operating temperature specifications while accommodating variations in physical dimensions and packaging formats.

Substitute Part Grouping Explanation

Substitute parts are grouped into three categories based on substitution type and compliance status:

Direct Equivalents (Same Tolerance ±20%):

• 173D685X0015V (Vishay Sprague, Tape & Box)
• 173D685X0015VW (Vishay Sprague, Tape & Reel)
• 173D685X0015VE3 (Vishay Sprague, Tape & Box, RoHS3 Compliant)
• 173D685X0015VWE3 (Vishay Sprague, Tape & Reel, RoHS3 Compliant)

These parts maintain identical electrical specifications: 6.8 µF capacitance, 15 V rating, ±20% tolerance, and -55°C to 125°C operating range. Physical dimensions vary slightly (0.110" Dia × 0.290" L vs. 0.098" Dia × 0.291" L), but remain compatible with axial through-hole mounting.

Upgraded Tolerance Parts (±10%):

• 173D685X9015VW (Vishay Sprague, Tape & Reel)
• 173D685X9015VWE3 (Vishay Sprague, Tape & Reel, RoHS3 Compliant)
• T322B685K015AS (KEMET, Bulk)
• T322B685K015AT (KEMET, referenced as substitute)

These parts provide tighter tolerance (±10%) while maintaining 6.8 µF, 15 V, and -55°C to 125°C specifications. Tighter tolerance represents an upgrade path for applications requiring improved capacitance accuracy.

Compliance Variants: RoHS3-compliant versions (173D685X0015VE3, 173D685X0015VWE3, 173D685X9015VWE3) are available for applications requiring regulatory compliance, while non-compliant versions remain available for legacy systems.

Engineering Selection Recommendations

For Direct Replacement (Legacy Systems): Select 173D685X0015VW or 173D685X0015V from Vishay Sprague. Both maintain identical electrical specifications to the obsolete TARR685M015. The 173D685X0015VW in Tape & Reel format is suitable for automated assembly, while 173D685X0015V in Tape & Box format accommodates manual placement. Both are active products with established supply chains.

For RoHS3 Compliance: Select 173D685X0015VWE3 (Tape & Reel) or 173D685X0015VE3 (Tape & Box) from Vishay Sprague. These parts provide identical electrical performance with RoHS3 compliance certification, required for applications subject to regulatory restrictions on hazardous substances.

For Improved Tolerance Requirements: Select 173D685X9015VW or 173D685X9015VWE3 from Vishay Sprague, or T322B685K015AS from KEMET. These parts upgrade tolerance to ±10%, providing tighter capacitance accuracy while maintaining all other electrical specifications. The KEMET T322B685K015AS offers bulk packaging for high-volume applications.

Packaging Considerations: Tape & Reel formats (VW, VWE3 designations) are optimized for pick-and-place assembly. Tape & Box formats (V, VE3 designations) support manual or semi-automated placement. Bulk packaging (KEMET T322B) is suitable for manual assembly or custom packaging workflows.

Frequently Asked Questions (FAQ)

Q: Can 173D685X0015VW directly replace TARR685M015 in existing designs? A: Yes. Both parts share identical electrical specifications: 6.8 µF, 15 V, ±20% tolerance, and -55°C to 125°C operating range. Physical dimensions vary slightly but remain compatible with standard axial through-hole PCB layouts. Verify PCB hole spacing accommodates the 0.110" diameter lead (vs. 0.098" original) if space constraints exist.

Q: What is the difference between 173D685X0015VW and 173D685X0015VWE3? A: Both parts are electrically identical. The VWE3 variant is RoHS3 compliant, while the standard VW is non-compliant. Select VWE3 for applications requiring regulatory compliance with hazardous substance restrictions. Both use Tape & Reel packaging.

Q: Should I use the ±10% tolerance parts (173D685X9015VW or T322B685K015AS)? A: The ±10% tolerance variants are upgrades suitable for applications requiring tighter capacitance accuracy. They are not required for direct replacement but offer improved performance. Verify circuit design tolerances before substitution.

Q: What packaging format should I select? A: Tape & Reel (VW, VWE3) is standard for automated assembly lines. Tape & Box (V, VE3) supports manual or semi-automated placement. Bulk (KEMET T322B) is used for custom packaging or manual assembly workflows. Confirm your assembly process requirements before selection.

Q: Are there any physical dimension incompatibilities? A: The substitute parts measure 0.110" Dia × 0.290" L compared to the original 0.098" Dia × 0.291" L. Verify PCB hole spacing and component clearance in confined layouts. Standard through-hole spacing typically accommodates this variation without modification.

Q: Can I mix compliance variants in the same production run? A: No. Maintain consistency within a production batch. Select either compliant (VE3) or non-compliant (standard) variants based on final product requirements. Mixing variants complicates traceability and compliance documentation.
