Substitute Part Grouping Explanation
Substitute parts for the 4-1879064-6 are categorized based on electrical parameter alignment and product status. The primary substitution criteria are:
Direct Electrical Equivalents (±20% Tolerance, 1.6 Ohm ESR): Parts maintaining identical capacitance (1 µF), voltage rating (50 V), tolerance (±20%), and ESR (1.6 Ohm) specifications. These parts are mechanically compatible within the 2312 package and support direct replacement without circuit redesign.
Upgraded Tolerance Variants (±10% Tolerance, 1.6 Ohm ESR): Parts with improved tolerance specification (±10% versus ±20%) while maintaining all other electrical parameters. These parts provide enhanced capacitance accuracy and are suitable for applications requiring tighter tolerance control.
Similar Performance Alternatives (±20% Tolerance, Higher ESR): Parts matching capacitance, voltage, and tolerance specifications but with elevated ESR values (4.4 Ohm to 5.5 Ohm). These parts maintain electrical functionality within the 2312 package but exhibit different impedance characteristics.
All substitute parts operate across the -55°C to 125°C temperature range, feature surface mount configuration, and comply with MSL 1 (Unlimited) moisture sensitivity classification.

Engineering Selection Recommendations
Direct Replacement (Electrical Equivalence): The Vishay Sprague 593D105X0050C2TE3 and TR3C105M050C1600 provide direct electrical equivalence to the 4-1879064-6, maintaining 1 µF capacitance, ±20% tolerance, 50 V rating, and 1.6 Ohm ESR. Both parts carry Active product status and ROHS3 compliance, ensuring long-term availability and regulatory conformance.
Upgraded Tolerance Selection: The Vishay Sprague 593D105X9050C2TE3 and TR3C105K050C1600 offer improved tolerance specification (±10%) while preserving all other electrical parameters. These parts are suitable for applications requiring enhanced capacitance accuracy and are available in Active status with ROHS3 compliance.
Alternative Performance Options: The TPSC105M050R2500 (KYOCERA AVX) provides the lowest ESR among alternatives at 2.5 Ohm while maintaining ±20% tolerance and 50 V rating. The T491C105M050AT (KEMET) and TAJC105M050RNJ (KYOCERA AVX) offer higher ESR values (4.8 Ohm and 5.5 Ohm respectively) and are suitable for general-purpose applications where ESR sensitivity is not critical.
Height Consideration: The TAJW105M050RNJ features a reduced seated height of 1.50 mm compared to the standard 2.70 mm to 2.80 mm range. This variant is applicable only to designs with specific height constraints within the 2312 package footprint.
All recommended substitute parts maintain the -55°C to 125°C operating temperature range, surface mount configuration, and MSL 1 (Unlimited) moisture sensitivity classification of the original component.
Frequently Asked Questions (FAQ)
Q: Can the 593D105X0050C2TE3 directly replace the 4-1879064-6 without circuit modification?
A: Yes. The 593D105X0050C2TE3 maintains identical electrical specifications: 1 µF capacitance, ±20% tolerance, 50 V rating, and 1.6 Ohm ESR. The 2312 package footprint and surface mount configuration are compatible. The seated height difference (2.79 mm versus 2.70 mm) is within standard PCB assembly tolerances.
Q: What is the difference between the ±20% and ±10% tolerance variants?
A: The ±10% tolerance variants (593D105X9050C2TE3 and TR3C105K050C1600) provide tighter capacitance accuracy compared to ±20% tolerance parts. Selection depends on circuit requirements for capacitance precision. Both tolerance grades maintain identical voltage, ESR, and temperature specifications.
Q: Why do some substitute parts have higher ESR values?
A: ESR (Equivalent Series Resistance) varies by manufacturer design and internal construction. Parts with higher ESR (4.4 Ohm to 5.5 Ohm) remain functionally equivalent for general-purpose applications but exhibit different impedance characteristics. Applications sensitive to ESR performance should select parts with matching or lower ESR specifications.
Q: Is the TAJW105M050RNJ suitable for all applications?
A: The TAJW105M050RNJ is suitable only for designs with specific height constraints. Its seated height of 1.50 mm is significantly lower than standard variants (2.70 mm to 2.80 mm). Verify PCB assembly clearance and component placement requirements before selection.
Q: Are all substitute parts RoHS3 compliant?
A: All substitute parts listed carry ROHS3 compliance certification. The original 4-1879064-6 does not specify RoHS status. Substitute parts provide regulatory compliance for applications requiring RoHS3 adherence.
Q: What is the inventory status of substitute parts?
A: All substitute parts are classified as Active product status with confirmed inventory availability. The original 4-1879064-6 is Obsolete. Active status ensures continued manufacturing and supply chain availability for production requirements.
Q: Can I use multiple substitute parts interchangeably in the same design?
A: Parts within the same tolerance and ESR classification (±20% tolerance, 1.6 Ohm ESR group) are interchangeable. Parts with different ESR values or tolerance specifications should not be mixed within the same circuit unless ESR variation is acceptable to circuit design parameters.
