Substitute Part Grouping Explanation

Substitution of the TE Connectivity 7-1676903-2 is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Capacitance: 6.8 µF (exact match required)
• Voltage Rating: 10 V (exact match required)
• Package / Case: 1411 (3528 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Type: Molded Tantalum (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Allowable Variation Parameters:

• Tolerance: ±20% (original) to ±10% (upgrade) — tighter tolerance represents an upgrade
• ESR: 3 Ohm (original) to 2.9 Ohm (substitute) — lower ESR represents an improvement
• Product Status: Obsolete (original) to Active (substitute) — active status ensures continued availability

The identified substitute parts from Vishay Sprague maintain all critical parameters while offering improved electrical characteristics and active product status.

Frequently Asked Questions (FAQ)

Q: Can the Vishay 293D685X0010B2TE3 be used as a direct replacement for the TE Connectivity 7-1676903-2?

A: Yes. The Vishay 293D685X0010B2TE3 maintains identical electrical specifications (6.8 µF, 10 V, ±20% tolerance) and mechanical package dimensions (1411 / 3528 Metric). The lower ESR (2.9 Ohm versus 3 Ohm) represents an improvement and does not create compatibility issues. No circuit modifications are required.

Q: What is the difference between the two Vishay substitute parts?

A: Both Vishay parts (293D685X0010B2TE3 and 293D685X9010B2TE3) are electrically and mechanically identical except for capacitance tolerance. The 293D685X0010B2TE3 maintains the original ±20% tolerance, while the 293D685X9010B2TE3 offers tighter ±10% tolerance. The upgraded tolerance part is suitable for applications requiring improved capacitance accuracy.

Q: Are the package dimensions identical across all three parts?

A: Yes. All three parts use the 1411 (3528 Metric) surface mount package with identical length (0.138" / 3.50mm) and width (0.110" / 2.80mm). Maximum seated height is 0.083" (2.10mm to 2.11mm), representing negligible variation within manufacturing tolerances.

Q: What is the significance of the obsolete status of the TE Connectivity part?

A: Obsolete status indicates the TE Connectivity 7-1676903-2 is no longer manufactured and will eventually become unavailable. The identified Vishay substitutes are active products with confirmed ongoing production, ensuring long-term supply chain continuity.

Q: Do the substitute parts meet the same regulatory requirements?

A: Yes. Both Vishay substitute parts maintain REACH unaffected status, ROHS3 compliance, EAR99 ECCN classification, and identical HTSUS code (8532.21.0050) as the original TE Connectivity part. Regulatory compliance is maintained across all three parts.

Q: Is the ESR difference between 3 Ohm and 2.9 Ohm significant?

A: The ESR difference of 0.1 Ohm represents a 3.3% improvement in the Vishay parts. This marginal reduction does not create compatibility issues and may provide slight performance benefits in applications sensitive to ESR characteristics. The lower ESR is not detrimental to circuit operation.

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. No desiccant packaging or baking procedures are required prior to soldering.
