Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 4-1879064-7 is determined by strict equivalence across the following parameters: capacitance value (1.5 µF), tolerance (±10%), rated voltage (50 V), package type (2312/6032 Metric), mounting method (Surface Mount), and operating temperature range (-55°C ~ 125°C). All substitute parts listed maintain these core electrical and mechanical specifications. Variations in ESR (Equivalent Series Resistance) are noted where they differ from the main part specification of 1.5 Ohm, as this parameter affects circuit performance characteristics. All substitute parts are classified as active product status from established manufacturers, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Identical ESR):

The parts 593D155X9050C2TE3 (Vishay Sprague), TPSC155K050R1500 (KYOCERA AVX), and TR3C155K050C1500 (Vishay Sprague) provide direct electrical equivalence to the TE Connectivity 4-1879064-7, maintaining the 1.5 Ohm ESR specification. All three are active product status with ROHS3 compliance, ensuring supply chain continuity and regulatory alignment. These parts are suitable for direct substitution in applications where ESR characteristics are critical to circuit performance.

Alternative Substitutes (Higher ESR):

The parts 293D155X9050C2TE3 (3.4 Ohm ESR), TAJC155K050RNJ (4.5 Ohm ESR), and TAJC155K050SNJ (4.5 Ohm ESR) maintain all core electrical specifications but feature elevated ESR values. These parts are active product status with ROHS3 compliance. Selection of these alternatives is appropriate when circuit design tolerates higher ESR or when supply availability of direct equivalents is constrained.

Compliance and Availability:

All substitute parts carry REACH Unaffected status and EAR99 ECCN classification, matching the regulatory profile of the original component. All substitute parts are available in active production status, eliminating obsolescence risk associated with the original TE Connectivity part.

Frequently Asked Questions (FAQ)

Q: Can the 593D155X9050C2TE3 directly replace the TE Connectivity 4-1879064-7?

A: Yes. The 593D155X9050C2TE3 maintains identical capacitance (1.5 µF), tolerance (±10%), voltage rating (50 V), ESR (1.5 Ohm), package (2312/6032 Metric), and operating temperature range (-55°C ~ 125°C). The seated height difference of 0.004" (0.09mm) is within standard PCB assembly tolerances.

Q: What is the significance of ESR differences among the substitute parts?

A: ESR (Equivalent Series Resistance) affects ripple current handling, thermal performance, and frequency response characteristics. Parts with 1.5 Ohm ESR (593D155X9050C2TE3, TPSC155K050R1500, TR3C155K050C1500) match the original specification. Parts with 3.4 Ohm or 4.5 Ohm ESR are suitable for applications where higher ESR is acceptable or where circuit design margins accommodate this variation.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed carry ROHS3 Compliant status, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the difference between the TAJC155K050RNJ and TAJC155K050SNJ parts?

A: Both parts are KYOCERA AVX TAJ series 1.5 µF, 50 V, 2312 package capacitors with 4.5 Ohm ESR. The parts maintain identical electrical specifications and are functionally equivalent. Packaging designation (RNJ vs. SNJ) reflects different tape and reel configurations for automated assembly.

Q: Can I use the 293D155X9050C2TE3 as a substitute if the original part is no longer available?

A: The 293D155X9050C2TE3 maintains all core electrical specifications (1.5 µF, ±10%, 50 V, 2312 package) but features 3.4 Ohm ESR compared to the original 1.5 Ohm. This part is suitable for substitution in applications where circuit design accommodates higher ESR or where performance margins are sufficient.

Q: What is the MSL (Moisture Sensitivity Level) for these capacitors?

A: All parts, including the original and all substitutes, carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: Are there any height clearance concerns when substituting these parts?

A: The original TE Connectivity part has a maximum seated height of 0.106" (2.70mm). All substitute parts have maximum seated heights of 0.110" (2.79mm or 2.80mm), representing a difference of 0.004" to 0.010" (0.09mm to 0.25mm). Standard PCB design clearances accommodate this variation.
