Substitution of the 1-1879062-6 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters for Direct Substitution:

Capacitance: 10 µF (exact match required)
Voltage Rating: 10 V (minimum; higher ratings acceptable)
Tolerance: ±20% (exact match or tighter tolerance acceptable)
Type: Molded Tantalum (exact match required)
Package / Case: 1206 (3216 Metric) (exact match required)
Mounting Type: Surface Mount (exact match required)
Operating Temperature Range: -55°C to 125°C (exact match required)
ESR: 2Ohm (exact match or lower acceptable)

Substitution Categories:

Direct Equivalents maintain all critical parameters including 10 V rating, ±20% tolerance, and 2Ohm ESR.

Upgrade Substitutes provide improved tolerance (±10% instead of ±20%) while maintaining all other critical parameters at the 10 V rating.

Similar Substitutes maintain all critical parameters but feature variations in ESR (higher than 2Ohm) or different lifetime specifications.

Voltage-Upgraded Substitutes provide higher voltage ratings (16 V) with different coating types (conformal coated instead of molded) and modified MSL classifications.

Engineering Selection Recommendations

Direct Equivalent Selection (Preferred for Obsolete Part Replacement):

The following parts provide direct electrical and mechanical equivalence to the 1-1879062-6:

593D106X0010A2TE3 (Vishay Sprague): Active product status, ROHS3 compliant, identical electrical specifications and physical dimensions. Recommended as primary replacement.
TR3A106M010C2000 (Vishay Sprague): Active product status, ROHS3 compliant, identical electrical specifications and physical dimensions. Recommended as secondary replacement.
TACV106M010RTA (KYOCERA AVX): Active product status, ROHS3 compliant, identical electrical specifications. Features reduced seated height (0.030" vs. 0.071"), suitable for space-constrained applications.

Upgrade Substitute Selection (Enhanced Tolerance):

The following parts provide improved tolerance specifications while maintaining all other critical parameters:

593D106X9010A2TE3 (Vishay Sprague): ±10% tolerance (vs. ±20%), active product status, ROHS3 compliant. Suitable for applications requiring tighter capacitance tolerance.
TR3A106K010C2000 (Vishay Sprague): ±10% tolerance (vs. ±20%), active product status, ROHS3 compliant. Suitable for applications requiring tighter capacitance tolerance.

Similar Substitute Selection (ESR Variation):

The following parts maintain all critical parameters but feature higher ESR values:

293D106X0010A2TE3 (Vishay Sprague): 3.4Ohm ESR (vs. 2Ohm), active product status, ROHS3 compliant. Acceptable where ESR increase does not impact circuit performance.
T491A106M010AT (KEMET): 3.8Ohm ESR (vs. 2Ohm), active product status, ROHS3 compliant, 2000 Hrs @ 125°C lifetime rating. Acceptable where ESR increase does not impact circuit performance.
T494A106M010AH (KEMET): 1.8Ohm ESR (vs. 2Ohm), active product status, RoHS non-compliant. Lower ESR provides performance advantage but non-compliance with RoHS3 may restrict use in regulated applications.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher voltage rating than the original 1-1879062-6?

A: Yes. Parts rated at 16 V (F951C106MSAAQ2 and F951C106KSAAQ2) are electrically compatible in circuits designed for 10 V operation. Higher voltage ratings provide additional safety margin. However, these parts feature conformal coating instead of molding and MSL 3 classification, requiring controlled moisture handling during assembly.

Q: What is the difference between molded and conformal coated tantalum capacitors?

A: The 1-1879062-6 uses molded construction with MSL 1 (unlimited moisture sensitivity). Conformal coated alternatives (F951C106MSAAQ2, F951C106KSAAQ2) feature protective coating and MSL 3 classification, requiring moisture bake-out procedures before soldering. Molded types are preferred for standard manufacturing environments.

Q: Are there differences in physical dimensions between substitute parts?

A: Yes. The TACV106M010RTA features a reduced seated height of 0.030" (0.75mm) compared to the original 0.071" (1.80mm). All other substitutes maintain the original 0.071" height. The reduced height option is suitable for applications with space constraints but must be verified for mechanical clearance.

Q: What does ESR variation mean for circuit performance?

A: ESR (Equivalent Series Resistance) affects ripple current handling and voltage transient response. The original part specifies 2Ohm. Substitutes with higher ESR (3.4Ohm, 3.8Ohm) generate more heat under AC current conditions. The T494A106M010AH with 1.8Ohm ESR provides improved performance. ESR differences are significant only in high-frequency or high-ripple-current applications.

Q: Which substitute offers the best direct replacement?

A: The 593D106X0010A2TE3 (Vishay Sprague) provides the most direct replacement, matching all electrical specifications (10 µF, 10 V, ±20%, 2Ohm ESR), physical dimensions, and product status (active, ROHS3 compliant).

Q: Can I use parts with ±10% tolerance instead of ±20%?

A: Yes. Parts with ±10% tolerance (593D106X9010A2TE3, TR3A106K010C2000) are compatible replacements. Tighter tolerance provides improved capacitance accuracy and is suitable for applications requiring stricter component specifications.

Q: What is MSL and why does it matter?

A: MSL (Moisture Sensitivity Level) indicates moisture absorption characteristics. MSL 1 (original part) requires no special handling. MSL 3 parts (conformal coated options) require moisture bake-out at 125°C for 24 hours before soldering to prevent delamination. MSL classification affects manufacturing procedures and storage requirements.

Q: Are all substitute parts RoHS compliant?

A: Most substitutes are ROHS3 compliant. The exception is T494A106M010AH, which is RoHS non-compliant. RoHS compliance is required for applications subject to EU regulations or customer specifications restricting hazardous substances.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Tape & Reel (TR) packaging is supplied on continuous reels for automated assembly. Cut Tape (CT) & Digi-Reel® packaging is supplied in smaller quantities on tape segments. Both are surface mount compatible. Selection depends on production volume and assembly equipment compatibility.
