TE Connectivity 2-1879063-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 2-1879063-2 is a 22 µF molded tantalum capacitor rated at 10 V with ±20% tolerance, housed in a 1411 (3528 Metric) surface mount package. This component belongs to the TYTR series and is classified as obsolete. The part features 700 mOhm equivalent series resistance and operates across a temperature range of -55°C to 125°C. Due to its obsolete product status, equivalent and substitute parts from active manufacturers are necessary for ongoing design support, production continuity, and component sourcing.

Engineering Selection Recommendations

Direct Substitutes (Identical Specifications):

The following parts provide direct electrical and mechanical equivalence to the TE Connectivity 2-1879063-2:

593D226X0010B2TE3 (Vishay Sprague TANTAMOUNT™ 593D series): Active product status with ROHS3 compliance. 2,300 units in stock.
T494B226M010AT (KEMET T494 series): Active product status with ROHS3 compliance and 2,000 hour lifetime rating at 125°C. 2,397 units in stock.
TR3B226M010C0700 (Vishay Sprague TANTAMOUNT™ TR3 series): Active product status with ROHS3 compliance. 4,400 units in stock.

All direct substitutes maintain 22 µF capacitance, 10 V voltage rating, ±20% tolerance, 700 mOhm ESR, and 1411 (3528 Metric) package specifications. All substitute parts are ROHS3 compliant and REACH unaffected.

Upgrade Options (Enhanced Performance):

Upgrade parts with improved tolerance (±10%) or higher voltage ratings (16 V) are available from both Vishay Sprague and KEMET. These upgrades maintain full electrical and mechanical compatibility while providing superior performance margins:

593D226X9010B2TE3 (Vishay Sprague, ±10% tolerance, 10 V): 6,479 units in stock.
T494B226K010AT (KEMET, ±10% tolerance, 10 V): 8,410 units in stock.

Selection between direct substitutes and upgrades depends on circuit design requirements. Direct substitutes are appropriate for applications requiring exact parameter matching. Upgrades with ±10% tolerance provide tighter capacitance control. Upgrades with 16 V rating provide increased voltage margin for applications operating near the 10 V limit.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with ±10% tolerance instead of ±20%?

A: Yes. Parts with ±10% tolerance (such as 593D226X9010B2TE3, T494B226K010AT, or TR3B226K010C0700) are electrically and mechanically compatible. The ±10% tolerance represents improved performance and tighter capacitance control compared to the original ±20% specification.

Q: Can I use a substitute part rated at 16 V instead of 10 V?

A: Yes. Parts rated at 16 V (such as 593D226X0016B2TE3, TR3B226K016C0700, or TR3B226M016C0700) are electrically and mechanically compatible. The higher voltage rating provides increased voltage margin and is suitable for applications where the original 10 V rating is adequate.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All active substitute parts listed are ROHS3 compliant. The original TE Connectivity 2-1879063-2 does not specify RoHS status due to its obsolete classification.

Q: Do all substitute parts have the same physical dimensions?

A: Yes. All substitute parts use the 1411 (3528 Metric) package with identical length (0.138" / 3.50 mm) and width (0.110" / 2.80 mm). Height specifications are 0.083" (2.10 mm) for the original part and 0.083" (2.11 mm) for substitute parts, representing negligible variation within standard manufacturing tolerances.

Q: What is the difference between the Vishay Sprague 593D and TR3 series?

A: Both series are TANTAMOUNT™ molded tantalum capacitors with identical electrical specifications for the 22 µF 10 V 700 mOhm configuration. The 593D series is available in both ±20% and ±10% tolerance options. The TR3 series is available in both ±20% and ±10% tolerance options with higher inventory availability for ±10% tolerance parts.

Q: Which substitute part has the longest operational lifetime rating?

A: The KEMET T494B226M010AT specifies 2,000 hours lifetime at 125°C. Other substitute parts do not provide explicit lifetime ratings in the provided specifications.

Q: Can I mix different substitute manufacturers in the same circuit board?

A: Yes. All substitute parts maintain identical electrical and mechanical specifications, allowing interchangeability within the same design. However, design documentation should reflect the specific part number used for traceability and future production runs.

Q: What is the MSL (Moisture Sensitivity Level) for all parts?

A: All parts, including the original and all substitutes, have MSL 1 (Unlimited), indicating no moisture sensitivity precautions are required during storage or handling.
