Engineering Selection Recommendations

Direct Equivalent Selection:

TAJW476M004RNJ (KYOCERA AVX) is the direct electrical equivalent to the TE Connectivity 1879064-8, maintaining identical capacitance (47 µF), voltage rating (4 V), tolerance (±20%), and ESR (500 mOhm) specifications. This part is active in production status and ROHS3 compliant. The primary advantage is a reduced seated height of 0.059" (1.50 mm) compared to the original 0.106" (2.70 mm), which may provide improved board-level clearance in space-constrained applications.

Upgrade Substitute Selection:

For applications requiring improved tolerance specifications, TAJW476K004RNJ (KYOCERA AVX) provides ±10% tolerance at the same 4 V rating and 500 mOhm ESR, with the same reduced height profile. This part is active and ROHS3 compliant.

For applications where circuit design permits higher voltage operation, the following upgrade substitutes are available:

TAJC476M016RNJ and TAJC476K016RNJ (KYOCERA AVX) provide 16 V ratings with ±20% and ±10% tolerances respectively, maintaining 500 mOhm ESR and 2312 package specifications.

Frequently Asked Questions (FAQ)

Q: Can TAJW476M004RNJ be used as a direct replacement for 1879064-8?

A: Yes. TAJW476M004RNJ is a direct electrical equivalent with identical capacitance (47 µF), voltage rating (4 V), tolerance (±20%), and ESR (500 mOhm). Both parts use the 2312 (6032 Metric) surface mount package. The primary difference is the reduced seated height (0.059" vs. 0.106"), which is a physical advantage in most applications.

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

A: Tolerance specifies the allowable deviation from the nominal capacitance value. A ±20% tolerance part (such as the original 1879064-8) allows capacitance values between 37.6 µF and 56.4 µF. A ±10% tolerance part allows values between 42.3 µF and 51.7 µF, providing tighter control. Applications requiring precise capacitance values should specify ±10% tolerance parts.

Q: Can I use a 10 V or 16 V rated capacitor in place of the 4 V original part?

A: Yes, provided the circuit design permits. Higher voltage-rated capacitors are electrically compatible with lower voltage applications. However, higher voltage ratings typically result in increased physical dimensions or different height profiles. Verify that the substitute part's physical dimensions (particularly seated height) are compatible with the PCB layout and component clearance requirements.

Q: What does ROHS3 compliance mean?

A: ROHS3 compliance indicates the part meets the Restriction of Hazardous Substances Directive 3, which restricts the use of specific hazardous materials in electrical and electronic equipment. All active substitute parts listed are ROHS3 compliant, ensuring regulatory compliance for new designs and production.

Q: Are Vishay Sprague TH3 series parts suitable for automotive applications?

A: Yes. The Vishay Sprague TH3C476M010C0500 and TH3C476K010C0500 parts carry AEC-Q200 automotive qualification, indicating they meet automotive industry reliability and performance standards. These parts are suitable for automotive and high-reliability applications requiring extended temperature operation (-55°C to 150°C).

Q: What is the significance of the package code "2312 (6032 Metric)"?

A: The 2312 designation is the EIA (Electronics Industries Alliance) code, while 6032 Metric is the metric equivalent. Both refer to the same physical package dimensions: 0.236" L × 0.126" W (6.00 mm × 3.20 mm). All substitute parts use this identical package, ensuring mechanical compatibility with the original design.

Q: Why does TAJW476M004RNJ have a lower seated height than the original part?

A: The KYOCERA AVX TAJ series uses optimized internal construction that achieves the same electrical specifications (47 µF, 4 V, 500 mOhm ESR) in a more compact form factor. The reduced height (0.059" vs. 0.106") provides design flexibility for space-constrained applications without compromising electrical performance.

Q: Can I mix different substitute parts in the same design?

A: All substitute parts maintain identical electrical specifications (47 µF capacitance, 500 mOhm ESR, and compatible voltage ratings). However, physical dimensions vary slightly between manufacturers. For consistency in PCB assembly and to avoid potential height-related clearance issues, use a single part number throughout a design.

Q: What is MSL (Moisture Sensitivity Level) and why is it important?

A: MSL indicates the component's sensitivity to moisture absorption during storage and handling. MSL 1 (Unlimited) means the part has no moisture sensitivity restrictions and can be stored indefinitely without special precautions. All parts listed carry MSL 1 rating, eliminating moisture-related handling concerns.
