Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1879063-9 is determined by strict equivalence across the following parameters: capacitance value (33 µF), tolerance (±10%), voltage rating, equivalent series resistance (500mOhm), package type (1411/3528 Metric), operating temperature range (-55°C ~ 125°C), and mounting configuration (surface mount).

Direct substitutes maintain identical electrical and mechanical specifications across all parameters. Upgrade substitutes provide higher voltage ratings while maintaining all other electrical and physical characteristics, permitting use in applications with lower voltage requirements.

The substitute parts are classified into two categories:

Direct Equivalents: Parts with identical voltage ratings (4 V) and all other specifications matching the original component.

Upgrade Substitutes: Parts with elevated voltage ratings (6.3 V or 16 V) that maintain identical capacitance, tolerance, ESR, package dimensions, and temperature range, suitable for applications where voltage margin enhancement is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection: For applications requiring exact electrical and mechanical compatibility with the original TE Connectivity 1879063-9, select either 593D336X9004B2TE3 or TR3B336K004C0500. Both parts are manufactured by Vishay Sprague, maintain active product status, and provide identical 4 V voltage rating with matching ESR and package specifications. The TR3B336K004C0500 offers ROHS3 compliance, providing enhanced regulatory alignment for new designs.

Upgrade Substitute Selection: The TR3B336K6R3C0500 (6.3 V) and TR3B336K016C0500 (16 V) are suitable for applications where voltage margin enhancement is required. These parts maintain identical capacitance, tolerance, ESR, and package dimensions while providing higher voltage ratings. Both parts are active products with ROHS3 compliance. The TR3B336K016C0500 offers the highest voltage margin and maintains the largest inventory availability (11,303 units).

All substitute parts maintain the same operating temperature range, moisture sensitivity level (MSL 1), and general-purpose feature set as the original component. Selection should be based on circuit voltage requirements and compliance certifications applicable to the end application.

Frequently Asked Questions (FAQ)

Q: Can the TR3B336K6R3C0500 or TR3B336K016C0500 be used as direct replacements for the 1879063-9?

A: Yes. Both upgrade substitutes maintain identical capacitance (33 µF), tolerance (±10%), ESR (500mOhm), package dimensions (1411/3528 Metric), and operating temperature range (-55°C ~ 125°C). The higher voltage ratings (6.3 V and 16 V respectively) are compatible with circuits designed for 4 V operation, as they provide additional voltage margin without affecting performance in lower-voltage applications.

Q: What is the difference between 593D336X9004B2TE3 and TR3B336K004C0500?

A: Both parts are direct equivalents with identical electrical specifications (33 µF, ±10%, 4 V, 500mOhm ESR) and package dimensions. The primary difference is that TR3B336K004C0500 carries ROHS3 compliance certification, while 593D336X9004B2TE3 does not specify this compliance. For new designs subject to ROHS3 requirements, TR3B336K004C0500 is the preferred selection.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts are supplied in Tape & Reel (TR) packaging. The original TE Connectivity 1879063-9 does not specify packaging format in the provided data. Verify packaging requirements for your procurement process, as Tape & Reel format is standard for surface mount tantalum capacitors in production environments.

Q: What is the significance of the height difference between the original part (2.10mm) and substitute parts (2.11mm)?

A: The height difference of 0.01mm (0.01 inches) is negligible for PCB assembly and does not affect mechanical compatibility. Both dimensions fall within standard surface mount assembly tolerances and do not require design modifications.

Q: Can these parts be used interchangeably in existing designs?

A: Direct equivalents (593D336X9004B2TE3 and TR3B336K004C0500) are fully interchangeable with the original 1879063-9 without design modification. Upgrade substitutes (TR3B336K6R3C0500 and TR3B336K016C0500) are compatible with existing designs but should be evaluated for compliance with circuit voltage specifications and any design margin requirements.

Q: What is the inventory status for each substitute part?

A: Current inventory levels are: 593D336X9004B2TE3 (854 units), TR3B336K004C0500 (783 units), TR3B336K6R3C0500 (1,006 units), and TR3B336K016C0500 (11,303 units). The TR3B336K016C0500 offers the highest availability for high-volume procurement requirements.
