The Vishay Sprague 195D106X9035Z2T is a surface-mount tantalum capacitor delivering 10 µF capacitance at a rated voltage of 35 V with ±10% tolerance. This component belongs to the TANTAMOUNT™ 195D series and features conformal coating, providing enhanced environmental protection for general-purpose applications across industrial and commercial electronics. The 2910 (7227 Metric) package measures 0.285" × 0.104" (7.24mm × 2.65mm) with a maximum seated height of 0.114" (2.90mm), offering a compact footprint suitable for space-constrained PCB layouts.
Conformal coating distinguishes this tantalum capacitor from standard molded variants by adding a protective layer that improves resistance to moisture, contaminants, and mechanical stress. This construction makes the 195D106X9035Z2T well-suited for environments where exposure to humidity or temperature cycling is expected. The operating temperature range of -55°C to 125°C supports deployment in automotive underhood systems, industrial control units, power conversion circuits, and outdoor telecommunications equipment where thermal excursions are routine.
The 10 µF capacitance value positions this component effectively in filtering and decoupling roles, particularly in voltage regulation stages, DC-DC converter output stages, and power supply bypass networks. At 35 V rated voltage, the capacitor provides adequate margin for 12 V, 24 V, and similar intermediate voltage rails commonly found in industrial motor drives, LED lighting drivers, and battery-powered systems. The ±10% tolerance ensures predictable performance in applications where precise capacitance is less stringent than volumetric efficiency.
Surface-mount construction in the 2910 case size enables automated pick-and-place assembly, reducing production time and improving placement accuracy compared to through-hole alternatives. The manufacturer size code Z corresponds to the physical dimensions and voltage rating within the Vishay Sprague nomenclature. Moisture Sensitivity Level 2A permits floor life of up to four weeks after bag opening at controlled ambient conditions, simplifying inventory management and production scheduling in high-volume manufacturing environments.
Tantalum capacitors are valued for stable capacitance across frequency and temperature, low leakage current, and higher volumetric efficiency than aluminum electrolytics of equivalent capacitance and voltage rating. The 195D series addresses general-purpose needs where cost-effectiveness and reliability intersect, making the 195D106X9035Z2T a practical choice for filtering high-frequency noise in switched-mode power supplies, supporting transient load response in point-of-load regulators, and stabilizing reference voltages in analog signal conditioning circuits. RoHS3 compliance and REACH unaffected status align with global electronics manufacturing standards for hazardous substance restrictions.

Replacing Vishay Sprague 195D106X9035Z2T: What Must Be Checked Before Choosing an Equivalent Tantalum Capacitor
When Vishay Sprague 195D106X9035Z2T is unavailable, approaching end-of-life in an approved BOM, or difficult to source in the required reel quantity, the replacement decision is not just a matter of matching “10 µF, 35 V.” This part is a surface-mount conformal-coated tantalum capacitor in a 2910 / 7227 metric package, so electrical rating, polarity, footprint, height, leakage behavior, surge robustness, and assembly compatibility all affect whether an alternative can be used safely.

These parts are not automatically interchangeable in every design. Some are closer electrical alternatives, while others use a different molded tantalum package that may require PCB land-pattern verification. A suitable 195D106X9035Z2T replacement should be selected by comparing capacitance tolerance, voltage derating margin, case size, soldering process, ESR expectations, reliability requirements, and the circuit function of the capacitor.
Understanding Vishay Sprague 195D106X9035Z2T Before Selecting a Replacement
Vishay Sprague 195D106X9035Z2T is a TANTAMOUNT 195D series conformal-coated tantalum capacitor. Its nominal capacitance is 10 µF with ±10% tolerance and a 35 V rated voltage. The package is 2910, also described as 7227 metric, with a Vishay size code Z. Its approximate body dimensions are 7.24 mm x 2.65 mm, with a maximum seated height of 2.90 mm. It is supplied in tape and reel for surface-mount assembly and is rated for operation from -55°C to +125°C.
These characteristics guide replacement evaluation in several ways. The 35 V voltage rating provides headroom for circuits using lower operating rails, but tantalum capacitors are commonly derated in practical designs, especially where surge current, hot-plug events, or low-impedance power sources are present. A replacement should therefore maintain the same 35 V rating unless the circuit has been reviewed for voltage stress, surge profile, and derating policy.
The conformal-coated 2910 body is another major factor. Many 10 µF 35 V tantalum alternatives are available in molded D-case / 2917 / 7343 packages. Electrically, these may be suitable, but mechanically they are wider than the original 7227-style device. If the PCB pads, component spacing, pick-and-place profile, or enclosure clearance were designed around the Vishay 195D Z case, a molded D-case replacement may not be a drop-in substitute.
The original part is intended for general-purpose functions such as local DC rail filtering, bulk decoupling near ICs, industrial control boards, instrumentation modules, telecom interface circuits, and power conditioning sections where stable capacitance over temperature is useful. In these applications, replacement suitability depends on the capacitor’s role. For bulk energy storage, capacitance and voltage rating may dominate. For regulator output filtering, ESR range and stability requirements may be more relevant. For dense boards, footprint and height can determine whether an otherwise suitable alternative can be used.

Among these candidates, 195D106X9035Z2TE3 is the closest replacement path because it remains in the same Vishay Sprague 195D family. The Vishay 293D106X9035D2TE3 and KEMET T491D106K035AT are stronger candidates when a standard molded tantalum D-case footprint is acceptable. The Vishay 593D106X9035D2TE3, KEMET T494D106K035AT, and KYOCERA AVX TPSD106K035R0300 should be evaluated when lower ESR is desired, especially in power filtering positions.
Engineering Trade-Offs When Comparing 195D106X9035Z2T Replacement Options
A practical comparison should focus on the risks introduced by substitution. The same capacitance and voltage rating do not guarantee the same board fit, solder profile behavior, ESR effect, or regulator stability. The table below summarizes the main engineering trade-offs between the candidate replacements.

For a near drop-in replacement of Vishay Sprague 195D106X9035Z2T, start with 195D106X9035Z2TE3 and confirm the ordering suffix, termination, packaging, and compliance status. If the PCB can accept a molded D-case tantalum, 293D106X9035D2TE3, T491D106K035AT, and TAJD106K035RNJ are practical general-purpose alternatives. If the capacitor is used in a power rail where lower ESR is beneficial, 593D106X9035D2TE3, T494D106K035AT, and TPSD106K035R0300 may provide better filtering performance, provided loop stability and surge current are reviewed.
