Substitute Part Grouping Explanation

Substitute parts for the 2-1879062-8 are classified into two categories based on electrical and mechanical compatibility:

Direct Equivalents maintain identical electrical specifications: 6.8 µF capacitance, 10 V voltage rating, ±20% tolerance, 3 Ohm ESR, and 1206 package format. These parts are functionally interchangeable without circuit modification.

Upgrade Options provide enhanced performance through improved tolerance (±10% instead of ±20%) or higher voltage ratings (16 V or 20 V instead of 10 V). These upgrades maintain the same capacitance value, package size, ESR, and temperature range, allowing direct substitution with potential circuit reliability improvements.

The critical parameters determining substitution eligibility are:

Capacitance value (6.8 µF)
Package / Case format (1206 / 3216 Metric)
Mounting type (Surface Mount)
ESR specification (3 Ohm)
Operating temperature range (-55°C to 125°C)

Engineering Selection Recommendations

Direct Equivalent Selection

For applications requiring exact electrical and mechanical compatibility with the 2-1879062-8, the following active parts provide direct substitution:

T494A685M010AT (KEMET T494 series): Offers the highest inventory availability at 2766 pieces with active product status and RoHS3 compliance. Rated lifetime of 2000 hours at 125°C provides documented reliability data.
TR3A685M010C3000 (Vishay Sprague TANTAMOUNT™ TR3 series): Active status with 770 pieces in stock and RoHS3 compliance. Suitable for applications where Vishay component qualification is required.
593D685X0010A2TE3 (Vishay Sprague TANTAMOUNT™ 593D series): Active status with 731 pieces available and RoHS3 compliance. Represents the 593D series alternative.

All direct equivalents maintain ±20% tolerance, 10 V rating, and 3 Ohm ESR specifications identical to the original part.

Upgrade Option Selection

For applications where circuit design permits enhanced specifications:

±10% Tolerance Upgrades: T494A685K010AT, TR3A685K010C3000, 593D685X9010A2TE3, and TR3A685K016C3000 provide tighter capacitance tolerance while maintaining 10 V or 16 V ratings. These upgrades improve circuit performance without package or mounting changes.
Higher Voltage Upgrades: 593D685X0016A2TE3 (16 V, ±20%) and T494A685M020AT (20 V, ±20%) accommodate circuits requiring increased voltage margin. These parts are direct mechanical and electrical substitutes with enhanced voltage headroom.

All substitute parts carry RoHS3 compliance and REACH Unaffected status, matching the regulatory profile of the original component.

Frequently Asked Questions (FAQ)

Q: Can I use a 16 V rated capacitor in place of the 10 V rated 2-1879062-8?

A: Yes. The 16 V and 20 V rated alternatives (593D685X0016A2TE3, 593D685X9016A2TE3, T494A685M020AT) are mechanically and electrically compatible substitutes. Higher voltage ratings provide additional safety margin in the circuit without affecting capacitance or package dimensions. These parts maintain the same 6.8 µF capacitance, 1206 package format, and 3 Ohm ESR.

Q: What is the difference between ±20% and ±10% tolerance options?

A: Tolerance specifies the allowable deviation from the nominal 6.8 µF capacitance value. The ±20% tolerance of the original part allows capacitance between 5.44 µF and 8.16 µF. The ±10% tolerance upgrades (T494A685K010AT, TR3A685K010C3000, 593D685X9010A2TE3, TR3A685K016C3000) restrict capacitance to 6.12 µF to 7.48 µF, providing tighter performance for applications requiring more precise capacitance values.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All active substitute parts listed are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The original 2-1879062-8 does not specify packaging format, but all equivalents are standardized in TR format for production environments.

Q: Do the substitute parts have the same operating temperature range?

A: Yes. All substitute parts operate across the identical temperature range of -55°C to 125°C, matching the original 2-1879062-8 specification. The KEMET T494 series provides documented lifetime of 2000 hours at 125°C.

Q: What is the Moisture Sensitivity Level (MSL) for these capacitors?

A: All parts, including the original and all substitutes, carry MSL 1 (Unlimited) rating. This indicates no moisture sensitivity restrictions and no special handling or storage requirements during assembly.

Q: Can I substitute between different manufacturers (TE Connectivity, KEMET, Vishay Sprague)?

A: Yes. All substitute parts maintain identical electrical specifications (6.8 µF, 10 V, ±20%, 3 Ohm ESR) and mechanical compatibility (1206 package, surface mount). Cross-manufacturer substitution is valid provided the specific part number specifications match your circuit requirements. Verify manufacturer qualification requirements for your application.

Q: What is the significance of the 3 Ohm ESR specification?

A: Equivalent Series Resistance (ESR) of 3 Ohm is a critical parameter for tantalum capacitor performance, affecting ripple current handling and frequency response. All listed substitutes maintain this 3 Ohm ESR specification, ensuring equivalent electrical behavior in the circuit.
