TE Connectivity 4-1879063-8 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 4-1879063-8 is a 6.8 µF molded tantalum capacitor rated for 20 V operation in a 1411 (3528 Metric) surface mount package. This component belongs to the TYTR series and is classified as obsolete. The part features 1 Ohm equivalent series resistance and operates across a temperature range of -55°C to 125°C with ±20% capacitance tolerance.

Due to the obsolete product status of the TE Connectivity 4-1879063-8, equivalent and upgraded substitute parts are available from Vishay Sprague. These alternatives maintain identical electrical and mechanical specifications while offering active product status and enhanced compliance certifications.

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 4-1879063-8 is determined by strict equivalence across the following parameters:

Direct Equivalents (±20% Tolerance): Direct substitutes maintain identical electrical specifications including 6.8 µF capacitance, 20 V voltage rating, ±20% tolerance, 1 Ohm ESR, and identical package dimensions. These parts are functionally interchangeable without circuit redesign.

Upgraded Alternatives (±10% Tolerance): Upgraded substitutes provide tighter capacitance tolerance (±10% versus ±20%) while maintaining all other electrical and mechanical parameters. These parts offer improved precision for applications requiring stricter capacitance control.

All substitute parts share the following mandatory compatibility criteria:

• Capacitance: 6.8 µF
• Voltage Rating: 20 V
• Package / Case: 1411 (3528 Metric)
• Mounting Type: Surface Mount
• ESR: 1 Ohm
• Operating Temperature: -55°C to 125°C
• Moisture Sensitivity Level: MSL 1

Engineering Selection Recommendations

For Direct Replacement (Functional Equivalence): Parts 593D685X0020B2TE3 and TR3B685M020C1000 provide direct functional equivalence to the TE Connectivity 4-1879063-8. Both are manufactured by Vishay Sprague, carry active product status, and maintain ROHS3 compliance. These parts are suitable for applications where the original ±20% tolerance specification is acceptable.

For Upgraded Performance (Tighter Tolerance): Parts 593D685X9020B2TE3 and TR3B685K020C1000 offer improved capacitance tolerance at ±10%, providing enhanced precision for circuits sensitive to capacitance variation. These upgrades maintain all other electrical and mechanical parameters while delivering active product status and ROHS3 compliance.

Compliance Considerations: All Vishay Sprague substitute parts are ROHS3 compliant and REACH unaffected, providing regulatory alignment for modern manufacturing environments. The TE Connectivity original part does not specify RoHS status, making the Vishay alternatives preferable for applications requiring documented compliance certifications.

Packaging and Logistics: All substitute parts are supplied in Tape & Reel (TR) packaging format, suitable for automated assembly processes. Physical dimensions remain consistent across all alternatives, with maximum seated height varying minimally (2.10mm to 2.11mm), presenting no practical impact on PCB layout or component clearance.

Frequently Asked Questions (FAQ)

Q: Can the Vishay Sprague parts directly replace the TE Connectivity 4-1879063-8 without circuit modification?

A: Yes. Parts 593D685X0020B2TE3 and TR3B685M020C1000 are direct functional equivalents. They maintain identical capacitance (6.8 µF), voltage rating (20 V), tolerance (±20%), ESR (1 Ohm), package dimensions (1411 / 3528 Metric), and operating temperature range (-55°C to 125°C). No circuit redesign is required.

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

A: The ±20% tolerance parts (593D685X0020B2TE3 and TR3B685M020C1000) allow capacitance values to vary within ±20% of the nominal 6.8 µF specification. The ±10% tolerance parts (593D685X9020B2TE3 and TR3B685K020C1000) provide tighter control, with capacitance values constrained to ±10% of nominal. Select ±10% parts for applications requiring stricter capacitance precision.

Q: Are there any physical dimension differences between the original and substitute parts?

A: Maximum seated height differs minimally: the TE Connectivity original specifies 0.083" (2.10mm), while Vishay Sprague substitutes specify 0.083" (2.11mm). This 0.01mm variation presents no practical impact on PCB layout, component clearance, or assembly processes.

Q: What packaging formats are available for the substitute parts?

A: All Vishay Sprague substitute parts are supplied in Tape & Reel (TR) packaging, optimized for automated surface mount assembly. This format differs from the original part's unspecified packaging but is standard for modern manufacturing environments.

Q: Do the substitute parts meet current compliance requirements?

A: Yes. All Vishay Sprague substitute parts are ROHS3 compliant and REACH unaffected. The original TE Connectivity part does not specify RoHS status. For applications requiring documented regulatory compliance, the Vishay alternatives provide certified compliance certifications.

Q: Which substitute part should be selected for new designs?

A: For new designs, select either 593D685X0020B2TE3 or TR3B685M020C1000 if ±20% tolerance is acceptable. If tighter capacitance control is required, select 593D685X9020B2TE3 or TR3B685K020C1000 (±10% tolerance). All four parts carry active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

Q: Are the substitute parts available in the same quantities as the original?

A: Inventory levels vary. The original TE Connectivity part shows 954 pieces in stock. Vishay Sprague substitutes show: 593D685X0020B2TE3 (1032 pieces), TR3B685M020C1000 (1048 pieces), 593D685X9020B2TE3 (689 pieces), and TR3B685K020C1000 (888 pieces).
