Engineering Selection Recommendations

Direct Substitutes (4 V, 150 mOhm):

The Vishay Sprague 593D227X9004D2TE3 and TR3D227K004C0150 are direct functional equivalents to the 1879065-5. Both parts maintain identical electrical specifications (220 µF, ±10%, 4 V, 150 mOhm) and package geometry. Both are ROHS3 compliant and carry active product status, ensuring long-term availability and supply chain stability. The 593D227X9004D2TE3 is supplied in Tape & Reel packaging with 1159 units in stock, while the TR3D227K004C0150 is supplied in Tape & Reel packaging with 909 units in stock.

Upgrade Options (Higher Voltage Rating):

For applications requiring enhanced voltage margin, the KEMET T494D227K006AT (6.3 V) and T494D227K010AT (10 V) provide identical capacitance, tolerance, and ESR specifications with increased voltage ratings. The KYOCERA AVX TPSD227K010R0150 and TPSD227K010Y0150 (both 10 V) and Vishay Sprague TR3D227K010C0150 (10 V) similarly provide voltage upgrades. All upgrade options are ROHS3 compliant and active products. The KEMET T494 series includes specified lifetime ratings of 2000 hours at 125°C.

Similar Alternatives (Differing ESR):

The Vishay Sprague 293D227X9004D2TE3 (600 mOhm ESR) and 293D227X9004E2TE3 (500 mOhm ESR) maintain the 4 V rating and 2917 package but feature higher ESR values. These parts are suitable for applications where ESR specifications are less stringent. The 592D227X9004D2T15H is a conformal-coated variant with 200 mOhm ESR and Moisture Sensitivity Level 2A, appropriate for environments requiring protective coating.

All substitute parts carry REACH Unaffected status and EAR99 ECCN classification, matching the regulatory profile of the original component.

Frequently Asked Questions (FAQ)

Q: Can I use a 10 V rated capacitor in place of the 4 V 1879065-5?

A: Yes. A 10 V rated capacitor with identical capacitance (220 µF), tolerance (±10%), ESR (150 mOhm), and package (2917) functions as a direct upgrade. The higher voltage rating provides additional safety margin and does not degrade circuit performance in applications designed for 4 V operation. Parts such as T494D227K010AT, TPSD227K010R0150, and TR3D227K010C0150 are suitable upgrades.

Q: What is the difference between the Vishay Sprague 593D227X9004D2TE3 and TR3D227K004C0150?

A: Both parts are direct equivalents with identical electrical specifications (220 µF, ±10%, 4 V, 150 mOhm, 2917 package). The primary difference is packaging format: the 593D227X9004D2TE3 is supplied in Tape & Reel format, while the TR3D227K004C0150 is supplied in Cut Tape & Digi-Reel format. Selection depends on assembly equipment compatibility and procurement requirements.

Q: Can I substitute a part with higher ESR, such as the 293D227X9004D2TE3 (600 mOhm)?

A: The 293D227X9004D2TE3 maintains the same capacitance, tolerance, voltage, and package but features 600 mOhm ESR compared to the original 150 mOhm. This higher ESR increases impedance and heat generation. Substitution is permissible only if circuit design specifications allow for the higher ESR value. Applications with strict ESR requirements must use parts with matching 150 mOhm specifications.

Q: What is the difference between molded and conformal-coated tantalum capacitors?

A: The 592D227X9004D2T15H is a conformal-coated variant, meaning the capacitor element is coated with a protective polymer layer. This provides enhanced moisture resistance (MSL 2A versus MSL 1) and is suitable for harsh environmental conditions. Conformal coating increases physical dimensions and may affect board layout. Use conformal-coated variants only when environmental protection is required.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All active substitute parts listed (Vishay Sprague 593D227X9004D2TE3, TR3D227K004C0150, TR3D227K010C0150; KEMET T494D227K006AT, T494D227K010AT; KYOCERA AVX TPSD227K010R0150, TPSD227K010Y0150; and Vishay Sprague 293D227X9004D2TE3, 293D227X9004E2TE3, 592D227X9004D2T15H) are ROHS3 compliant, ensuring compatibility with modern manufacturing and environmental regulations.

Q: What inventory levels are available for direct substitutes?

A: The Vishay Sprague 593D227X9004D2TE3 has 1159 units in stock, and the TR3D227K004C0150 has 909 units in stock. For 10 V upgrades, the KYOCERA AVX TPSD227K010R0150 has the highest inventory at 1,000,400 units, followed by TR3D227K010C0150 with 5600 units and TPSD227K010Y0150 with 1072 units.

Q: Do all substitute parts operate across the same temperature range?

A: Yes. All substitute parts operate across the -55°C to 125°C temperature range, matching the original 1879065-5 specification. The KEMET T494 series provides additional lifetime specification of 2000 hours at 125°C.
