Engineering Selection Recommendations

Direct Substitutes (10 V Rating):

TAJA106M010RNJ (KYOCERA AVX) and F931A106MAA (KYOCERA AVX) are direct electrical and mechanical substitutes for the TE Connectivity 7-1676903-3. Both parts maintain the 10 V voltage rating, ±20% tolerance, 10 µF capacitance, and 1206 package dimensions. Both are active product status with ROHS3 compliance, providing superior availability and regulatory compliance compared to the obsolete original part.

Upgrade Substitutes (16 V Rating):

Parts with 16 V voltage ratings provide higher voltage margin while maintaining all other electrical and mechanical specifications. These include F931C106MAA, F931C106KAA, 293D106X0016A2TE3, 293D106X9016A2TE3, and T494A106M016AH. The 16 V rating is backward compatible with 10 V circuit requirements and provides design flexibility for future applications.

Alternative Construction (Conformal Coated):

F951C106KQAAQ2 and F951C106MQAAQ2 (KYOCERA AVX) offer conformal coated tantalum construction at 16 V rating. These parts feature reduced seated height (0.063" versus 0.071") and MSL 3 rating. Conformal coating provides enhanced environmental protection for applications requiring moisture resistance.

Compliance Considerations:

All substitute parts except T494A106M016AH carry ROHS3 compliance certification. T494A106M016AH is RoHS non-compliant and should be selected only when legacy compliance requirements apply. KYOCERA AVX and Vishay Sprague substitutes provide active product status with established supply chains and manufacturing continuity.

Frequently Asked Questions (FAQ)

Q: Can F931A106MAA replace the TE Connectivity 7-1676903-3 directly?

A: Yes. F931A106MAA maintains identical electrical specifications (10 µF, 10 V, ±20% tolerance, 3 Ohm ESR) and mechanical compatibility (1206 package, 0.071" height, surface mount). The part is active status with ROHS3 compliance, providing improved availability over the obsolete original.

Q: What is the difference between direct substitutes and upgrade substitutes?

A: Direct substitutes maintain the 10 V voltage rating of the original part. Upgrade substitutes feature 16 V voltage rating, providing higher voltage margin while remaining electrically compatible with 10 V circuit applications. Upgrade substitutes are backward compatible and suitable for designs requiring additional voltage headroom.

Q: Are conformal coated tantalum capacitors (F951 series) compatible with molded tantalum designs?

A: Conformal coated parts are electrically compatible but feature different physical characteristics. F951C106KQAAQ2 and F951C106MQAAQ2 have reduced seated height (0.063" versus 0.071") and higher moisture sensitivity level (MSL 3 versus MSL 1). Conformal coating provides enhanced environmental protection for specific application requirements.

Q: What does ±10% tolerance mean compared to ±20%?

A: Tolerance specifies the allowable deviation from the nominal 10 µF capacitance value. ±10% tolerance (F931A106KAA, F931C106KAA, 293D106X9016A2TE3) provides tighter capacitance accuracy with acceptable deviation between 9.0 µF and 11.0 µF. ±20% tolerance (original part and most substitutes) allows deviation between 8.0 µF and 12.0 µF. Tighter tolerance parts are suitable for applications requiring precise capacitance values.

Q: Is the 1206 package dimension identical across all substitute parts?

A: Yes. All substitute parts use the 1206 (3216 Metric) package with identical length (0.126") and width (0.063") dimensions. Molded tantalum substitutes maintain 0.071" maximum seated height. Conformal coated substitutes (F951 series) feature reduced 0.063" maximum seated height due to alternative construction. Physical footprint compatibility is maintained across all molded variants.

Q: Why do some parts specify ESR at 100kHz while others do not?

A: ESR (Equivalent Series Resistance) is frequency-dependent. KYOCERA AVX parts specify ESR @ 100kHz as a standard measurement condition. TE Connectivity and other manufacturers specify ESR without frequency notation, typically measured at standard test conditions. All parts maintain 3 Ohm ESR specification, ensuring equivalent performance in circuit applications.

Q: What is the significance of MSL (Moisture Sensitivity Level)?

A: MSL indicates the component's sensitivity to moisture absorption during storage and handling. MSL 1 (unlimited shelf life) applies to most molded tantalum substitutes, allowing indefinite storage without baking requirements. MSL 3 (168 hours) applies to conformal coated parts, requiring moisture control during storage and baking before reflow soldering. MSL rating affects component handling procedures but does not affect electrical performance.

Q: Are ROHS3 compliant parts required for all applications?

A: ROHS3 compliance is mandatory for products sold in European Union markets and many other regulated regions. All substitute parts except T494A106M016AH carry ROHS3 certification. T494A106M016AH is RoHS non-compliant and suitable only for legacy applications or markets without RoHS requirements. Verify regulatory requirements for your specific application before part selection.

Q: Can parts with different manufacturers be mixed in the same design?

A: Yes. All substitute parts maintain identical electrical specifications and mechanical compatibility. Mixing manufacturers (KYOCERA AVX, Vishay Sprague, KEMET) is acceptable from an engineering standpoint. However, supply chain and procurement considerations may favor single-manufacturer selections for production consistency and inventory management.
