Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-1879063-3 is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Capacitance value: 68 µF
• Tolerance: ±10%
• Voltage rating: 4 V
• Package designation: 1411 (3528 Metric)
• Mounting type: Surface Mount
• Operating temperature range: -55°C ~ 125°C
• Moisture sensitivity level: 1 (Unlimited)

The Vishay Sprague 293D686X9004B2TE3 satisfies all critical matching parameters. Both components are molded tantalum capacitors with identical electrical ratings and physical package specifications. The substitute part is classified as active product status, providing continued availability for new designs and replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The Vishay Sprague 293D686X9004B2TE3 is the direct equivalent substitute for the obsolete TE Connectivity 1-1879063-3. Selection of the substitute part is supported by the following factors:

Product Status: The Vishay Sprague component maintains active product status, ensuring long-term availability and supply chain continuity compared to the obsolete TE Connectivity part.

Electrical Equivalence: Both capacitors deliver identical capacitance (68 µF), voltage rating (4 V), and tolerance (±10%). The substitute exhibits marginally lower ESR (1.9 Ohm versus 2 Ohm), which provides equivalent or improved performance characteristics in filtering and energy storage applications.

Mechanical Compatibility: Identical package designation (1411/3528 Metric), physical dimensions, and surface mount configuration ensure direct board-level substitution without layout modifications.

Regulatory Compliance: Both components maintain REACH Unaffected status and EAR99 export classification. The substitute part carries RoHS3 Compliance certification, meeting current environmental and regulatory requirements.

Thermal Performance: Matching operating temperature range (-55°C ~ 125°C) and moisture sensitivity level (MSL 1) confirm functional equivalence across specified environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the Vishay Sprague 293D686X9004B2TE3 be used as a direct replacement for the TE Connectivity 1-1879063-3?

A: Yes. Both components are 68 µF, 4 V molded tantalum capacitors in identical 1411 (3528 Metric) surface mount packages with matching electrical ratings and operating temperature ranges. No circuit modifications or board layout changes are required.

Q: What is the significance of the ESR difference between the two parts?

A: The Vishay Sprague substitute exhibits 1.9 Ohm ESR compared to 2 Ohm for the TE Connectivity original. This marginal reduction in equivalent series resistance provides equivalent or improved performance in filtering applications and does not introduce compatibility concerns.

Q: Are there any packaging or moisture sensitivity differences?

A: No. Both components feature identical MSL 1 (Unlimited) moisture sensitivity classification and are supplied in equivalent surface mount packaging configurations. Storage and handling requirements are identical.

Q: Does the substitute part meet current regulatory requirements?

A: Yes. The Vishay Sprague 293D686X9004B2TE3 carries RoHS3 Compliance certification and maintains REACH Unaffected status, meeting current environmental and export regulations. The original TE Connectivity part is classified as REACH Unaffected but does not carry RoHS3 certification.

Q: Are the physical dimensions identical between the two parts?

A: Yes. Both components measure 0.138" L x 0.110" W (3.50mm x 2.80mm) with maximum seated heights of 0.083" (2.10mm and 2.11mm respectively). These dimensions are functionally equivalent for PCB assembly and clearance calculations.

Q: What is the availability status of each part?

A: The TE Connectivity 1-1879063-3 is classified as obsolete. The Vishay Sprague 293D686X9004B2TE3 maintains active product status with established supply chain availability.
