Substitute Part Grouping Explanation

Substitution of the TE Connectivity 5-1879062-2 is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria (Exact Match Required):

Capacitance: 4.7 µF
Voltage Rating: 20 V
Tolerance: ±20%
Package / Case: 1206 (3216 Metric)
Mounting Type: Surface Mount
Operating Temperature Range: -55°C to 125°C
ESR: 3.5 Ohm

Direct Equivalents maintain all primary substitution criteria and are sourced from active manufacturers. These parts are functionally interchangeable with the original component.

Upgrade Substitutes improve upon the original specification by reducing tolerance from ±20% to ±10%, or by increasing voltage rating from 20 V to 25 V, while maintaining all other parameters. These upgrades provide enhanced performance characteristics suitable for applications requiring tighter capacitance tolerances or higher voltage margins.

Similar Substitutes deviate from the original ESR specification (ranging from 1.8 Ohm to 5 Ohm) or differ in packaging format (Cut Tape vs. Tape & Reel). These parts maintain electrical functionality but introduce variations in series resistance or supply format that may affect circuit performance or procurement logistics.

Engineering Selection Recommendations

Direct Equivalent Selection (Preferred for Drop-In Replacement):

The Vishay Sprague parts 593D475X0020A2TE3 and TR3A475M020C3500 provide direct electrical and mechanical equivalence to the TE Connectivity 5-1879062-2. Both components maintain identical capacitance (4.7 µF), voltage rating (20 V), tolerance (±20%), ESR (3.5 Ohm), and package specifications (1206). Both manufacturers are active, ROHS3 compliant, and maintain unlimited moisture sensitivity levels. These parts are suitable for direct substitution in applications where the original specification must be preserved.

Upgrade Substitute Selection (Enhanced Performance):

The Vishay Sprague parts 593D475X9020A2TE3 and TR3A475K020C3500 offer improved tolerance specifications (±10% versus ±20%) while maintaining all other electrical parameters. These upgrades are appropriate for applications requiring tighter capacitance tolerances. The parts TR3A475K025C3500 and TR3A475M025C3500 provide increased voltage ratings (25 V versus 20 V) with either ±10% or ±20% tolerance, offering enhanced voltage margin for circuits operating near the original 20 V specification limit.

Similar Substitute Selection (Alternative Considerations):

The KYOCERA AVX TAJA475M020RNJ, TAJA475M020SNJ, and TPSA475M020R1800 maintain the core electrical specifications (4.7 µF, 20 V, ±20%) but introduce variations in ESR (ranging from 1.8 Ohm to 4 Ohm). The TPSA475M020R1800 features significantly lower ESR (1.8 Ohm) compared to the original 3.5 Ohm specification, which may alter circuit performance in applications sensitive to series resistance. The Vishay Sprague 293D475X0020A2TE3 presents higher ESR (5 Ohm) than the original specification. These parts are suitable only when ESR variation is acceptable to the application design.

All recommended substitutes are ROHS3 compliant and maintain the -55°C to 125°C operating temperature range of the original component.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with different ESR than the original 5-1879062-2?

A: ESR variation affects circuit performance, particularly in high-frequency applications and power supply circuits. The original part specifies 3.5 Ohm ESR. Substitutes with different ESR values (such as TPSA475M020R1800 at 1.8 Ohm or 293D475X0020A2TE3 at 5 Ohm) will alter impedance characteristics. Use only when circuit design tolerates ESR variation.

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

A: Direct equivalents (593D475X0020A2TE3, TR3A475M020C3500) match all specifications of the original part, including ±20% tolerance and 3.5 Ohm ESR. Upgrade substitutes improve specific parameters: tolerance upgrades reduce tolerance to ±10%, and voltage upgrades increase the rating to 25 V. Upgrades are backward compatible but provide enhanced performance characteristics.

Q: Can I substitute a 25 V rated part for the original 20 V specification?

A: Yes. The TR3A475K025C3500 and TR3A475M025C3500 are rated for 25 V, which exceeds the original 20 V requirement. Higher voltage ratings provide additional safety margin and are suitable for applications where the circuit voltage does not exceed 20 V. This substitution is appropriate for long-term reliability improvement.

Q: Are all substitute parts ROHS3 compliant?

A: All active substitute parts listed are ROHS3 compliant. The original TE Connectivity 5-1879062-2 is classified as REACH Unaffected. All Vishay Sprague and KYOCERA AVX substitutes maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on continuous reels suitable for automated assembly equipment. Cut Tape & Digi-Reel packaging provides components in tape format cut to specific lengths, typically for smaller quantity orders or manual assembly. The TAJA475M020RNJ is supplied in Cut Tape & Digi-Reel format, while most other substitutes use Tape & Reel format. Packaging format does not affect electrical performance but impacts procurement and assembly logistics.

Q: Which substitute part has the highest inventory availability?

A: The KYOCERA AVX TPSA475M020R1800 maintains the highest inventory level at 13,696 pieces. This part features the lowest ESR (1.8 Ohm) among available substitutes. The KYOCERA AVX TAJA475M020RNJ provides 2,400 pieces with 4 Ohm ESR and Cut Tape packaging. Both parts are suitable for high-volume procurement requirements.

Q: Can I use a ±10% tolerance part in place of the original ±20% tolerance specification?

A: Yes. The ±10% tolerance parts (593D475X9020A2TE3, TR3A475K020C3500) provide tighter capacitance accuracy than the original ±20% specification. This upgrade is suitable for applications requiring improved capacitance stability and is backward compatible with designs that accept the original ±20% tolerance.
