TE Connectivity 7-1879062-7 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 7-1879062-7 is a 0.47 µF molded tantalum capacitor rated for 35 V with 1206 (3216 Metric) surface mount packaging. This component is classified as obsolete, necessitating identification of active equivalent alternatives that maintain identical electrical and mechanical specifications. Substitute parts must match the core parameters: 0.47 µF capacitance, ±10% tolerance, 35 V rated voltage, 1206 package format, and surface mount configuration.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: capacitance value (0.47 µF), voltage rating (35 V), tolerance (±10%), package type (1206/3216 Metric), and mounting method (surface mount). All substitute parts listed maintain these core electrical and mechanical specifications.

Equivalent Series Resistance (ESR) varies among substitute options (ranging from 4Ohm to 12Ohm) and represents a secondary parameter that does not disqualify substitution but indicates performance variation. Parts are grouped into two categories: direct equivalents with matching ESR specifications and similar alternatives with acceptable ESR variance within typical application tolerances.

Engineering Selection Recommendations

Direct Equivalents (Matching ESR - 4Ohm):

The Vishay Sprague parts 593D474X9035A2TE3 and TR3A474K035C4000 provide direct electrical equivalence to the TE Connectivity 7-1879062-7, maintaining identical ESR specifications of 4Ohm. Both parts are active products with ROHS3 compliance and are available in high inventory quantities. These parts are the primary recommendation for direct replacement applications.

Secondary Equivalents (ESR Variance - 6Ohm to 12Ohm):

Parts with higher ESR values (TPSA474K035R6000 at 6Ohm, 293D474X9035A2TE3 at 10Ohm, and KEMET/KYOCERA AVX options at 12Ohm) maintain all core electrical specifications but exhibit increased equivalent series resistance. These alternatives are suitable for applications where ESR variance does not impact circuit performance. All secondary equivalents are active products with ROHS3 compliance, except T491A474K035AH which is RoHS non-compliant.

Compliance Considerations:

For applications requiring RoHS3 compliance, all substitute parts except T491A474K035AH meet this requirement. All parts maintain REACH Unaffected status and EAR99 export classification consistent with the original component.

Height Variation:

TAJS474K035RNJ features a reduced seated height of 0.047" (1.20mm) compared to the standard 0.071" (1.80mm) specification. This part is suitable only for applications where reduced height clearance is required or beneficial.

Frequently Asked Questions (FAQ)

Q: Can I substitute the TE Connectivity 7-1879062-7 with any of the listed alternatives?

A: All listed parts maintain the core specifications of 0.47 µF capacitance, 35 V rating, ±10% tolerance, 1206 package, and surface mount configuration. Direct substitution is supported for all alternatives. ESR differences do not prevent substitution but may affect circuit performance in applications sensitive to impedance characteristics.

Q: What is the difference between direct equivalents and secondary equivalents?

A: Direct equivalents (593D474X9035A2TE3 and TR3A474K035C4000) match the original 4Ohm ESR specification. Secondary equivalents have higher ESR values (6Ohm to 12Ohm) but maintain all other electrical and mechanical parameters. Selection depends on circuit requirements for impedance characteristics.

Q: Are all substitute parts RoHS compliant?

A: Seven of the eight substitute parts are ROHS3 compliant. T491A474K035AH is RoHS non-compliant. For applications requiring RoHS compliance, select from the seven ROHS3-compliant alternatives.

Q: Does the height difference of TAJS474K035RNJ affect compatibility?

A: TAJS474K035RNJ has a seated height of 0.047" (1.20mm) versus the standard 0.071" (1.80mm). This reduced height is compatible with PCB layouts designed for standard 1206 packages but provides additional clearance. Verify PCB design requirements before selecting this part.

Q: What packaging options are available?

A: Substitute parts are available in Cut Tape (CT), Digi-Reel, and Tape & Reel (TR) packaging formats. Verify packaging requirements for your procurement and assembly processes.

Q: Can I use parts with different ESR values interchangeably?

A: All parts are electrically equivalent in terms of capacitance, voltage, and tolerance. ESR differences may affect circuit performance in applications with specific impedance requirements, such as high-frequency filtering or low-noise applications. Evaluate circuit sensitivity to ESR before selecting alternatives with ESR values differing from the original 4Ohm specification.
