Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 2-1879063-9 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 15 µF (exact match required)
• Voltage Rating: 16 V (exact match required)
• Tolerance: ±10% (exact match required)
• ESR: 800 mOhm (exact match required)
• Package / Case: 1411 (3528 Metric) (exact match required)
• Physical Dimensions: 0.138" L x 0.110" W (3.50 mm x 2.80 mm) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Type: Molded Tantalum (exact match required)

All identified substitute parts meet these criteria and are sourced from active manufacturers with current product status and RoHS3 compliance certification.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts provide direct functional equivalence to the obsolete TE Connectivity 2-1879063-9. Selection among active alternatives is based on the following criteria:

Product Status and Compliance: All substitute parts carry active product status from established manufacturers (Vishay Sprague and KEMET), ensuring long-term availability and supply chain continuity. All substitutes are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Packaging Availability:

• 593D156X9016B2TE3 (Vishay Sprague): Available in Tape & Reel (TR) packaging with 1936 units in stock
• T494B156K016AT (KEMET): Available in Tape & Reel (TR) packaging with 2538 units in stock
• T495B156K016ATE800 (KEMET): Available in Cut Tape (CT) & Digi-Reel® packaging with 2842 units in stock
• TR3B156K016C0800 (Vishay Sprague): Available in Tape & Reel (TR) packaging with 1053 units in stock

Thermal Performance: T494B156K016AT specifies 2000 hours lifetime at 125°C. T495B156K016ATE800 specifies 2000 hours lifetime at 85°C. Vishay Sprague parts (593D156X9016B2TE3 and TR3B156K016C0800) do not specify lifetime ratings but maintain full operating temperature range equivalence.

Physical Compatibility: All substitutes maintain identical footprint dimensions (0.138" L x 0.110" W) and maximum seated height within 0.01 mm variance, ensuring direct board-level compatibility without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the 2-1879063-9 be directly replaced with any of these substitute parts?

A: Yes. All four substitute parts are electrically and mechanically equivalent. They share identical capacitance (15 µF), voltage rating (16 V), tolerance (±10%), ESR (800 mOhm), package type (1411 / 3528 Metric), and operating temperature range (-55°C to 125°C). Direct substitution on the PCB is possible without circuit modification.

Q: What is the difference between the Vishay Sprague and KEMET options?

A: Both manufacturers provide equivalent parts meeting all electrical and mechanical specifications. Vishay Sprague offers the 593D156X9016B2TE3 and TR3B156K016C0800 in Tape & Reel packaging. KEMET offers the T494B156K016AT in Tape & Reel and T495B156K016ATE800 in Cut Tape & Digi-Reel packaging. Selection depends on packaging preference and inventory availability.

Q: Are there packaging differences that affect compatibility?

A: Packaging format (Tape & Reel vs. Cut Tape & Digi-Reel) affects handling and assembly processes but does not impact electrical or mechanical compatibility. The component itself remains identical regardless of packaging format.

Q: Do all substitutes meet current regulatory standards?

A: Yes. All four substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The original TE Connectivity part does not specify RoHS status.

Q: What is the height difference between parts, and does it matter?

A: The original part specifies maximum seated height of 0.083" (2.10 mm). Vishay Sprague substitutes specify 0.083" (2.11 mm), a variance of 0.01 mm. KEMET parts specify 0.083" (2.10 mm). This minimal variance is within standard PCB assembly tolerances and does not affect board-level compatibility.

Q: Which substitute has the best thermal performance?

A: Both KEMET parts specify 2000-hour lifetime ratings: T494B156K016AT at 125°C and T495B156K016ATE800 at 85°C. Vishay Sprague parts do not provide lifetime specifications but maintain full operating temperature range equivalence.

Q: Can I mix different substitute parts in the same design?

A: Yes. All substitutes are electrically and mechanically equivalent and can be used interchangeably within the same circuit or across multiple production batches without performance variation.
