TE Connectivity 3-1879062-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 3-1879062-1 is a 10 µF molded tantalum capacitor rated at 16 V in a 1206 (3216 Metric) surface mount package. This component belongs to the TYTR series and is classified as obsolete. The part features a 3 Ohm equivalent series resistance (ESR) and operates across a temperature range of -55°C to 125°C, making it suitable for general-purpose applications in compact form factors.

Due to the obsolete product status of the 3-1879062-1, identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production, repair, and redesign activities. Active alternatives with identical or compatible electrical and mechanical specifications are available from multiple manufacturers.

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 3-1879062-1 is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

Capacitance: 10 µF (exact match required)
Voltage Rating: 16 V (exact match required)
Tolerance: ±10% (exact match required)
Package / Case: 1206 (3216 Metric) (exact match required)
Mounting Type: Surface Mount (exact match required)
Operating Temperature Range: -55°C to 125°C (exact match required)

Secondary Compatibility Criteria:

ESR (Equivalent Series Resistance): 3 Ohm (primary specification) or lower ESR values (1.7 Ohm) are acceptable as they represent improved performance
Type: Molded tantalum (primary) or conformal coated tantalum (acceptable with MSL consideration)
Moisture Sensitivity Level: MSL 1 (preferred) or MSL 3 (acceptable with appropriate handling)

Parts are grouped into two categories:

Direct Substitutes (Molded Tantalum, 3 Ohm ESR): Parts with identical electrical and mechanical specifications, including ESR of 3 Ohm and molded construction.

Compatible Alternatives (Lower ESR or Conformal Coating): Parts meeting all primary criteria but with improved ESR performance (1.7 Ohm) or alternative construction (conformal coated), which provide enhanced reliability or environmental protection while maintaining full functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with lower ESR (1.7 Ohm instead of 3 Ohm)?

A: Yes. Lower ESR values represent improved electrical performance. Parts such as 593D106X9016A2TE3 and TR3A106K016C1700 with 1.7 Ohm ESR are fully compatible substitutes. Lower ESR reduces heat dissipation and improves transient response, providing a performance margin over the original specification.

Q: What is the difference between molded and conformal coated tantalum capacitors?

A: Molded tantalum capacitors feature a standard epoxy molded case. Conformal coated tantalum capacitors (such as F951C106KQAAQ2) have an additional protective coating applied to the component surface, providing enhanced environmental protection against moisture and contaminants. Conformal coated parts carry a higher MSL rating (MSL 3 vs. MSL 1) and require controlled moisture handling during assembly.

Q: Are all substitute parts RoHS compliant?

A: Yes. All active substitute parts listed are ROHS3 compliant. The original TE Connectivity 3-1879062-1 does not specify RoHS status due to its obsolete classification, but all recommended substitutes meet current RoHS3 requirements.

Q: What does MSL 1 (Unlimited) mean?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture sensitivity concerns. Components with MSL 1 do not require special moisture-controlled storage or baking procedures prior to assembly. This applies to most substitute parts listed, with the exception of F951C106KQAAQ2, which carries MSL 3 (168 hours).

Q: Can I substitute the TE Connectivity part with a KYOCERA AVX TAJ series part?

A: Yes. KYOCERA AVX TAJ series parts (TAJA106K016RNJ, TAJA106K016SNJ, TAJA106K016YNJ) are direct substitutes with identical electrical and mechanical specifications. The primary difference is packaging format: some are supplied in Cut Tape and Digi-Reel format, while others are supplied in Tape and Reel format. Select based on your assembly equipment requirements.

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

A: Cut Tape and Digi-Reel packaging is supplied on individual tape segments suitable for manual or semi-automated assembly. Tape and Reel packaging is supplied on continuous reels suitable for high-speed automated assembly equipment. Both formats contain identical components; selection depends on your production assembly process.

Q: Does the seated height difference in F951C106KQAAQ2 affect compatibility?

A: The F951C106KQAAQ2 has a maximum seated height of 0.063" (1.60mm) compared to 0.071" (1.80mm) for the original part. This lower profile is advantageous in space-constrained applications and does not create compatibility issues. The component will fit in any PCB footprint designed for the original part. Verify clearance if the application has height restrictions.

Q: Which substitute part has the highest inventory availability?

A: TAJA106K016RNJ (KYOCERA AVX) has the highest inventory availability at 1,313,400 pieces in stock, followed by F931C106KAA (KYOCERA AVX) at 327,584 pieces. These parts are suitable for high-volume production requirements.

Q: Are all substitute parts rated for -55°C to 125°C operation?

A: Yes. All substitute parts listed maintain the same operating temperature range of -55°C to 125°C as the original TE Connectivity 3-1879062-1. This ensures thermal compatibility across all specified operating conditions.

Q: Which substitute parts include lifetime specifications?

A: F931C106KAA (KYOCERA AVX) and T491A106K016AT (KEMET) both include specified lifetime ratings of 2000 hours at 125°C. These documented reliability specifications provide additional confidence for critical applications requiring extended operational life data.
