The T95D336K025HZSS from Vishay Sprague is classified as a direct manufacturer substitute with a higher voltage rating of 25 V. This part maintains the 33 µF capacitance, ±10% tolerance, and 2917 package specification. The conformal coated construction provides enhanced environmental protection compared to the molded type of the original part. ESR is 260 mOhm, marginally higher than the original 250 mOhm. This part carries active product status and ROHS3 compliance.

Upgrade Substitutes (Higher Voltage Rating):

The KEMET T494D336K016AT offers a 16 V rated voltage with identical 33 µF capacitance and ±10% tolerance in the 2917 package. This molded tantalum capacitor maintains 250 mOhm ESR matching the original specification. The part is active, ROHS3 compliant, and carries REACH Unaffected status. Lifetime rating of 2000 hours at 125°C is specified.

Frequently Asked Questions (FAQ)

Q: Can I use a 25 V rated substitute in place of the 10 V original part?

A: Yes. Higher voltage ratings are acceptable substitutes for lower voltage applications. The 25 V rated parts (T95D336K025HZSS, T95D336K025CSSS, T95D336K025CSZS, T95D336K025CZSS, T95D336K025HSAS, T95D336K025HZAS) function correctly in circuits designed for 10 V operation. The higher voltage rating provides additional safety margin.

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

A: Molded tantalum capacitors feature a plastic encapsulation, while conformal coated variants have a thin polymer coating applied directly to the component. Conformal coated types generally offer improved moisture resistance and environmental protection. Both types are acceptable substitutes provided all other electrical parameters match.

Q: Why do some substitute parts have higher ESR values?

A: ESR (Equivalent Series Resistance) varies based on construction type and manufacturing process. The original part specifies 250 mOhm ESR. Substitute parts with 260 mOhm ESR (Vishay T95 series) are marginally higher but functionally equivalent. Parts with 300 mOhm or 800 mOhm ESR represent significant variations and should be evaluated for specific circuit requirements related to ripple current handling and thermal performance.

Q: Are there physical size differences between substitute parts?

A: Minor dimensional variations exist. The original part measures 0.287" L x 0.169" W with 0.118" maximum seated height. Most substitute parts measure 0.293" L x 0.170" W with 0.122" maximum seated height. The 592D336X9010D2T15H variant has significantly reduced height at 0.059" (1.50mm). These variations are within typical PCB layout tolerances for 2917 package components.

Q: What is MSL (Moisture Sensitivity Level) and why does it matter?

A: MSL indicates the component's sensitivity to moisture absorption during storage and handling. MSL 1 (Unlimited) means the part has no moisture sensitivity restrictions. MSL 2A (4 Weeks) requires the component to be used within 4 weeks of package opening or requires baking before reflow soldering. The original part carries MSL 1 rating. Substitute parts with MSL 2A require appropriate moisture control procedures.

Q: Which substitute part is the best direct replacement?

A: The KEMET T494D336K016AT provides the closest electrical match with identical 250 mOhm ESR, molded construction, and MSL 1 rating. It offers 16 V rated voltage, providing voltage margin above the original 10 V specification. This part is active, ROHS3 compliant, and carries specified lifetime rating of 2000 hours at 125°C.

Q: Can I use the 592D336X9010D2T15H with its significantly lower height?

A: The 592D336X9010D2T15H maintains the 2917 package specification and electrical parameters (33 µF, ±10%, 10 V). However, its height of 0.059" (1.50mm) is substantially lower than the original 0.118" (3.00mm). This part is suitable only if PCB layout and component clearance constraints permit the reduced height. Conformal coated construction and 300 mOhm ESR are acceptable for most applications.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts carry ROHS3 compliance status. The original TE Connectivity part does not specify RoHS status. All active substitute parts meet current RoHS3 requirements for lead-free and restricted substance compliance.
