Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 4-1879064-5 is determined by strict equivalence across the following parameters: capacitance value (1 µF), tolerance (±10%), voltage rating (50 V), package type (2312/6032 Metric), mounting method (surface mount), and operating temperature range (-55°C to 125°C). All substitute parts must maintain these electrical and mechanical specifications to ensure direct compatibility in circuit applications.

Equivalent series resistance (ESR) varies among substitute options and is provided for engineering evaluation. Parts are grouped into two categories: direct equivalents with matching ESR specifications (1.6 Ohm), and similar alternatives with higher ESR values (2.5 Ohm to 5.5 Ohm). All substitute parts maintain MSL 1 rating and REACH compliance status.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Matching ESR 1.6 Ohm):

The Vishay Sprague 593D105X9050C2TE3 and TR3C105K050C1600 provide direct electrical equivalence to the TE Connectivity 4-1879064-5, maintaining the 1.6 Ohm ESR specification. Both parts are active products with ROHS3 compliance and unlimited moisture sensitivity rating. The TR3C105K050C1600 offers higher inventory availability (2267 pcs) compared to the 593D variant (966 pcs). These parts are suitable for direct replacement in applications where ESR performance is critical.

Alternative Options (Higher ESR Values):

The KYOCERA AVX TPSC105K050R2500 provides the lowest ESR alternative at 2.5 Ohm with substantial inventory (25400 pcs) and active product status. The Vishay Sprague 293D105X9050C2TE3 offers 4.6 Ohm ESR with high availability (2400 pcs). The KEMET T491C105K050AT and KYOCERA AVX TAJC105K050RNJ both feature 5.5 Ohm ESR; the TAJC variant provides significantly higher inventory (45200 pcs).

All substitute parts maintain compliance with REACH regulations and MSL 1 moisture sensitivity classification. Selection should prioritize direct equivalents where ESR specifications are design-critical, or alternative options where ESR tolerance permits higher values.

Frequently Asked Questions (FAQ)

Q: Can the Vishay Sprague 593D105X9050C2TE3 directly replace the TE Connectivity 4-1879064-5?

A: Yes. The 593D105X9050C2TE3 maintains identical electrical specifications (1 µF, 50 V, ±10% tolerance, 1.6 Ohm ESR) and mechanical compatibility (2312 package, surface mount). Both parts operate across -55°C to 125°C and carry MSL 1 rating. The substitute is an active product with ROHS3 compliance.

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

A: Equivalent series resistance affects capacitor performance in high-frequency applications and ripple current handling. The original part specifies 1.6 Ohm ESR. Direct equivalents (593D105X9050C2TE3, TR3C105K050C1600) maintain this value. Alternative parts with higher ESR (2.5 to 5.5 Ohm) may be suitable for applications with less stringent ESR requirements but should be evaluated against circuit specifications.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed are ROHS3 compliant. The original TE Connectivity part does not specify RoHS status. All alternatives meet current environmental compliance standards.

Q: What packaging formats are available for these substitutes?

A: The Vishay Sprague 593D105X9050C2TE3 and TR3C105K050C1600 are supplied in Tape & Reel (TR) format. The KEMET T491C105K050AT and KYOCERA AVX TPSC105K050R2500 are available in Cut Tape (CT) & Digi-Reel® format. The KYOCERA AVX TAJC105K050RNJ is supplied in Tape & Reel format. Packaging selection depends on production volume and assembly requirements.

Q: Do all substitute parts share the same operating temperature range?

A: Yes. All substitute parts operate across the identical temperature range of -55°C to 125°C, matching the original TE Connectivity specification.

Q: Is the height difference between the original part (2.70 mm) and substitutes (2.79-2.80 mm) significant?

A: The height variation of 0.09-0.10 mm falls within typical PCB design tolerances for surface mount components. This difference is not significant for standard applications but should be verified against specific board clearance requirements in space-constrained designs.
