Key Parameters

Substitute Part Grouping Explanation

Substitution of the T86C155K035EBAL is based on the following critical parameters that must remain constant:

• Capacitance value: 1.5 µF
• Tolerance: ±10%
• Voltage rating: 35 V
• Package type: 2312 (6032 Metric)
• Mounting type: Surface Mount
• Physical dimensions: 0.236" L x 0.126" W (6.00mm x 3.20mm)
• Height: 0.110" (2.80mm) maximum

The substitute part TH3C155K035D3300 meets all these core electrical and mechanical requirements, maintaining full compatibility with the original design specifications.

Parameter Comparison

Engineering Selection Recommendations

The TH3C155K035D3300 is a direct functional substitute for the obsolete T86C155K035EBAL. Both components are manufactured by Vishay Sprague and share identical electrical specifications (1.5 µF, ±10%, 35 V) and mechanical form factors (2312 package, surface mount).

The substitute part offers several advantages:

• Active production status ensures long-term availability
• ROHS3 compliance meets current regulatory requirements
• AEC-Q200 automotive qualification provides additional reliability assurance
• Extended operating temperature range (-55°C to 150°C versus -55°C to 125°C)
• Slightly higher ESR (3.3 Ohm versus 2.6 Ohm) remains within acceptable operational parameters for most applications

Selection of the TH3C155K035D3300 is appropriate for new designs and replacement applications where the original T86C155K035EBAL is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the TH3C155K035D3300 be used as a direct replacement for the T86C155K035EBAL?

A: Yes. Both parts share identical capacitance (1.5 µF), tolerance (±10%), voltage rating (35 V), package type (2312), and physical dimensions. The substitute is electrically and mechanically compatible.

Q: What is the difference in ESR between these parts?

A: The T86C155K035EBAL has an ESR of 2.6 Ohm, while the TH3C155K035D3300 has an ESR of 3.3 Ohm. This difference is within acceptable operational limits for molded tantalum capacitors in this class and does not affect functional compatibility.

Q: Why does the substitute part have a higher operating temperature maximum?

A: The TH3C155K035D3300 is rated to 150°C versus the original part's 125°C. This extended range is a design improvement in the newer TH3 series and provides additional thermal margin without compromising compatibility.

Q: Are there compliance differences between these parts?

A: Yes. The T86C155K035EBAL is RoHS non-compliant, while the TH3C155K035D3300 is ROHS3 compliant. The substitute also carries AEC-Q200 automotive qualification, making it suitable for applications requiring current regulatory compliance.

Q: Will the substitute part fit in the same PCB footprint?

A: Yes. Both parts use the 2312 (6032 Metric) package with identical dimensions (0.236" L x 0.126" W, 6.00mm x 3.20mm) and maximum seated height (0.110", 2.80mm).
