Equivalent & Substitute Parts for TE Connectivity 2-1879063-8

Part Overview

The TE Connectivity 2-1879063-8 is a 6.8 µF molded tantalum capacitor rated at 10 V with ±20% tolerance, housed in a 1411 (3528 Metric) surface mount package. This component is classified as obsolete, necessitating identification of active substitute parts that maintain electrical and mechanical compatibility. Substitute parts must preserve the capacitance value, package dimensions, mounting type, and operating temperature range while accommodating variations in voltage rating and tolerance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 2-1879063-8 are qualified based on the following critical parameters:

Mandatory Compatibility Parameters:

• Capacitance: 6.8 µF (exact match required)
• Package / Case: 1411 (3528 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• ESR: 1.2 Ohm (exact match required)
• Type: Molded Tantalum (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: Substitutes must equal or exceed 10 V
• Tolerance: Substitutes may vary from ±20%
• Product Status: Active substitutes preferred over obsolete

The substitute parts identified (TR3B685K025C1200 and TR3B685M025C1200) maintain all mandatory parameters while providing upgraded voltage ratings of 25 V, representing a direct functional upgrade with enhanced voltage margin.

Parameter Comparison

Engineering Selection Recommendations

TR3B685K025C1200 (Vishay Sprague TANTAMOUNT™ TR3 Series)

This substitute provides a 6.8 µF capacitor with improved tolerance specification (±10% versus ±20%) and elevated voltage rating (25 V versus 10 V). The part is active in production status and carries ROHS3 compliance certification. The tighter tolerance specification offers enhanced capacitance accuracy for applications requiring precision. This configuration is suitable for designs where improved tolerance performance and regulatory compliance are required.

TR3B685M025C1200 (Vishay Sprague TANTAMOUNT™ TR3 Series)

This substitute maintains the original ±20% tolerance specification while providing the same 25 V voltage upgrade and active product status. The part carries ROHS3 compliance certification. This configuration is suitable for direct replacement in applications where tolerance specifications match the original design and regulatory compliance is required.

Both substitutes are electrically and mechanically compatible with the original TE Connectivity 2-1879063-8 component. Selection between the two Vishay Sprague options depends on tolerance requirements: TR3B685K025C1200 for ±10% tolerance applications, or TR3B685M025C1200 for ±20% tolerance applications.

Frequently Asked Questions (FAQ)

Q: Can TR3B685K025C1200 or TR3B685M025C1200 be used as direct replacements for 2-1879063-8?

A: Yes. Both Vishay Sprague parts maintain identical capacitance (6.8 µF), package dimensions (1411/3528 Metric), ESR (1.2 Ohm), operating temperature range (-55°C ~ 125°C), and mounting type (surface mount). The 25 V voltage rating exceeds the original 10 V specification, providing functional compatibility with voltage margin.

Q: What is the difference between TR3B685K025C1200 and TR3B685M025C1200?

A: The primary difference is tolerance specification. TR3B685K025C1200 provides ±10% tolerance, while TR3B685M025C1200 provides ±20% tolerance. Both parts share identical voltage rating (25 V), capacitance (6.8 µF), ESR (1.2 Ohm), and package specifications.

Q: Are the physical dimensions identical between the original and substitute parts?

A: Physical dimensions are equivalent. Length and width are identical at 0.138" L x 0.110" W (3.50mm x 2.80mm). Maximum seated height differs marginally: original at 0.083" (2.10mm) and substitutes at 0.083" (2.11mm), representing a 0.01mm variation within standard manufacturing tolerances.

Q: Do the substitute parts meet regulatory compliance requirements?

A: Both Vishay Sprague substitutes carry ROHS3 compliance certification. Both parts maintain REACH Unaffected status and EAR99 ECCN classification, consistent with the original component.

Q: What is the moisture sensitivity level for the substitute parts?

A: Both substitute parts maintain MSL 1 (Unlimited) classification, identical to the original TE Connectivity component.

Q: Can these parts be used interchangeably in the same circuit board design?

A: Yes. The identical package footprint (1411/3528 Metric), mounting type (surface mount), and physical dimensions enable direct board-level substitution without design modification.
