Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 5-1879064-0 are classified into three categories based on electrical and mechanical compatibility:

Direct Substitutes (Equivalent Parameters): Parts that match all critical electrical specifications including capacitance (2.2 µF), voltage rating (50 V), tolerance (±20%), ESR (1.5 Ohm), package (2312), and operating temperature range (-55°C to 125°C). These parts are interchangeable without circuit modification.

Upgrade Substitutes (Enhanced Tolerance): Parts that maintain identical capacitance, voltage, ESR, package, and temperature specifications but feature tighter tolerance (±10% instead of ±20%). These provide improved precision and are backward compatible with designs specified for ±20% tolerance.

Similar Substitutes (Modified ESR): Parts that match capacitance, voltage, tolerance, package, and temperature specifications but have different ESR values. These require circuit evaluation to confirm suitability based on application-specific ESR requirements.

The key parameters determining substitution eligibility are: capacitance value, voltage rating, package type, mounting method, operating temperature range, and ESR specification.

Engineering Selection Recommendations

Direct Substitutes (Recommended for Pin-Compatible Replacement):

The parts 593D225X0050C2TE3 (Vishay Sprague), T494C225M050AT (KEMET), and TR3C225M050C1500 (Vishay Sprague) are direct electrical and mechanical equivalents to the obsolete TE Connectivity 5-1879064-0. All three maintain identical capacitance, voltage rating, tolerance, and ESR specifications. These parts are manufactured by active suppliers with ROHS3 compliance and unlimited moisture sensitivity rating. The maximum seated height varies slightly (2.79mm to 2.80mm) but remains within acceptable PCB assembly tolerances. These parts are suitable for direct substitution without circuit redesign.

Upgrade Substitutes (Enhanced Precision):

The parts 593D225X9050C2TE3 and TR3C225K050C1500 (both Vishay Sprague) offer tighter tolerance (±10%) while maintaining all other specifications identical to the original part. These upgrades provide improved capacitance accuracy and are backward compatible with designs specified for ±20% tolerance. Both parts are active products with ROHS3 compliance. Selection of upgrade parts is appropriate when circuit performance benefits from improved capacitance precision.

Similar Substitutes (ESR Variation):

The parts 293D225X0050C2TE3 (Vishay Sprague, 2.9 Ohm ESR) and TAJC225M050RNJ (KYOCERA AVX, 3.0 Ohm ESR) maintain all specifications except ESR. These parts are suitable only when circuit design permits higher ESR values. Applications with strict ESR requirements should not use these alternatives without circuit analysis.

All recommended substitutes are from active manufacturers with current product status and ROHS3 compliance certification.

Frequently Asked Questions (FAQ)

Q: Can I use 593D225X9050C2TE3 as a direct replacement for 5-1879064-0?

A: Yes. The 593D225X9050C2TE3 is electrically and mechanically compatible. It maintains identical capacitance (2.2 µF), voltage rating (50 V), ESR (1.5 Ohm), package (2312), and operating temperature range (-55°C to 125°C). The tighter tolerance (±10% versus ±20%) represents an upgrade that improves precision without affecting compatibility.

Q: What is the difference between direct substitutes and upgrade substitutes?

A: Direct substitutes (593D225X0050C2TE3, T494C225M050AT, TR3C225M050C1500) match all specifications of the original part including ±20% tolerance. Upgrade substitutes (593D225X9050C2TE3, TR3C225K050C1500) provide the same electrical performance but with tighter ±10% tolerance, offering improved capacitance accuracy.

Q: Why do some substitute parts have different ESR values?

A: ESR (Equivalent Series Resistance) varies based on internal construction and manufacturing process. Parts 293D225X0050C2TE3 (2.9 Ohm) and TAJC225M050RNJ (3.0 Ohm) have higher ESR than the original 1.5 Ohm specification. These parts are suitable only for applications where higher ESR does not degrade circuit performance.

Q: Are all substitute parts RoHS compliant?

A: All recommended substitute parts are ROHS3 compliant. The original TE Connectivity 5-1879064-0 does not specify RoHS status. All active manufacturer alternatives meet current RoHS3 requirements.

Q: What is the maximum height difference between the original part and substitutes?

A: The original part has a maximum seated height of 0.106" (2.70mm). Substitute parts range from 0.110" (2.79mm) to 0.110" (2.80mm). This 0.04mm to 0.10mm height variation is within standard PCB assembly tolerances and does not affect mechanical fit or electrical performance.

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

A: Yes. All direct substitutes and upgrade substitutes are electrically and mechanically interchangeable. However, using parts with different ESR values (293D225X0050C2TE3 or TAJC225M050RNJ) in the same circuit may affect performance if ESR-sensitive filtering or impedance characteristics are critical to circuit function.

Q: Which substitute part has the best availability?

A: TAJC225M050RNJ (KYOCERA AVX) has the highest inventory level at 1620 pieces. 593D225X9050C2TE3 (Vishay Sprague) has 1208 pieces. T494C225M050AT (KEMET) has 1076 pieces. All three represent active products with strong supply availability.

Q: Is the moisture sensitivity level the same across all parts?

A: Yes. The original part and all substitute parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
