Substitute Part Grouping Explanation

Substitution of the T54EE337M016CSS025 is determined by strict equivalence across the following critical parameters: capacitance value (330 µF), voltage rating (16 V), ESR specification (25 mOhm @ 100kHz), package configuration (2917 / 7343 Metric), tolerance (±20%), operating temperature range (-55°C to 125°C), and lifetime rating (2000 Hrs @ 125°C). The substitute part T54EE337M016CSA025 maintains identical electrical and mechanical specifications across all these parameters. The only distinction between the main part and its substitute is the packaging format designation (CSS025 versus CSA025), which reflects different tape and reel configurations from the same manufacturer series. Both parts are manufactured by Vishay Polytech within the vPolyTan™ T54 series and carry identical compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the T54EE337M016CSS025 and T54EE337M016CSA025 are qualified for direct substitution based on complete electrical and mechanical parameter equivalence. Both parts maintain active production status within the vPolyTan™ T54 series and carry identical ROHS3 compliance certification. Selection between these two part numbers is determined solely by packaging and tape reel configuration requirements specified by the assembly process or procurement system. The CSS025 and CSA025 designations represent different tape and reel specifications from Vishay Polytech; the electrical performance, thermal characteristics, reliability ratings, and physical dimensions are identical. Component selection should be based on the specific tape and reel format required by the manufacturing or assembly equipment. Both parts are suitable for applications requiring 330 µF capacitance at 16 V with 25 mOhm ESR in surface mount 2917 package configurations.

Frequently Asked Questions (FAQ)

Q: Can T54EE337M016CSA025 be used as a direct replacement for T54EE337M016CSS025?

A: Yes. Both parts are electrically and mechanically identical. The difference between CSS025 and CSA025 designations refers only to the tape and reel packaging configuration. If the assembly equipment or procurement specification does not mandate a specific tape reel format, either part number can be used interchangeably.

Q: What is the difference between CSS025 and CSA025 packaging designations?

A: CSS025 and CSA025 are Vishay Polytech's internal designations for different tape and reel configurations. Both deliver the same 330 µF, 16 V molded tantalum polymer capacitor in the 2917 (7343 Metric) package. The distinction is in the physical tape and reel format used for automated assembly line feeding. Verify your assembly equipment specifications to determine which format is required.

Q: Are both parts ROHS3 compliant?

A: Yes. Both T54EE337M016CSS025 and T54EE337M016CSA025 are ROHS3 compliant and carry identical environmental and regulatory certifications.

Q: What is the MSL rating for these capacitors?

A: Both parts carry MSL 3 rating with a 168-hour moisture sensitivity window. This indicates the maximum time the component can be exposed to ambient conditions (typically 30°C / 85% RH) before soldering must be completed.

Q: Can these parts be used in applications requiring operation below -55°C or above 125°C?

A: No. The specified operating temperature range is -55°C to 125°C. Applications requiring operation outside this range require alternative component selection.

Q: What is the significance of the 25 mOhm ESR specification?

A: The 25 mOhm ESR (Equivalent Series Resistance) at 100 kHz is a critical electrical parameter that determines the capacitor's impedance characteristics at high frequencies. This specification is identical between both part numbers and must be maintained for circuit performance equivalence.

Q: Are inventory levels a factor in component substitution?

A: Inventory availability is a supply chain consideration but does not affect electrical or mechanical substitution eligibility. Both parts are manufactured by Vishay Polytech and are in active production status.
