Substitute Part Grouping Explanation

Substitution eligibility for the T54EE157M030CSS075 is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Capacitance value (150 µF), rated voltage (30 V), and ESR (75 mOhm @ 100 kHz) must match exactly. These parameters directly affect circuit performance and reliability.

Mechanical Compatibility: Package designation (2917 / 7343 Metric), mounting type (Surface Mount), and physical dimensions (0.287" L x 0.169" W / 7.30 mm x 4.30 mm) must be identical to ensure PCB footprint compatibility.

Environmental & Reliability Ratings: Operating temperature range (-55°C ~ 125°C), lifetime specification (2000 Hrs @ 125°C), and moisture sensitivity level (MSL 3) must remain constant.

Compliance Standards: RoHS3 compliance status must be maintained for regulatory equivalence.

Substitute parts identified within this specification set are direct functional and mechanical equivalents suitable for one-to-one replacement.

Parameter Comparison

Engineering Selection Recommendations

Both the T54EE157M030CSS075 and T54EE157M030CSA075 are active production components from Vishay Polytech's vPolyTan™ T54 series. Selection between these equivalent parts may be based on inventory availability and supply chain considerations. The T54EE157M030CSS075 maintains higher stock levels (1101 pieces) compared to the T54EE157M030CSA075 (1024 pieces). Both parts carry identical electrical specifications, mechanical dimensions, and compliance certifications (RoHS3, COTS rating, REACH Unaffected status for the substitute). The difference in part number designation (CSS075 versus CSA075) reflects internal Vishay manufacturing or packaging variation codes that do not affect functional equivalence. For applications requiring immediate availability, the primary part number is preferred. For supply chain redundancy or long-term sourcing strategies, the substitute part number provides equivalent performance and reliability characteristics.

Frequently Asked Questions (FAQ)

Q: Can T54EE157M030CSA075 be used as a direct replacement for T54EE157M030CSS075?

A: Yes. Both parts are identical in electrical specifications (150 µF, 30 V, 75 mOhm ESR), mechanical dimensions (2917 package, 7.30 mm x 4.30 mm), and operating characteristics (-55°C ~ 125°C, 2000 Hrs @ 125°C). They are direct one-to-one substitutes.

Q: What determines substitution eligibility for this capacitor?

A: Substitution is based on exact matching of capacitance (150 µF), rated voltage (30 V), ESR (75 mOhm @ 100 kHz), package type (2917 / 7343 Metric), physical dimensions, operating temperature range, and compliance status (RoHS3). Any deviation in these parameters disqualifies a part from being a true equivalent.

Q: Are there any differences in the packaging or lead configuration between these parts?

A: No. Both parts use identical Tape & Reel (TR) packaging, surface mount configuration, and 2917 (7343 Metric) package format. PCB footprints and assembly processes are identical.

Q: What is the significance of the part number suffix (CSS075 vs. CSA075)?

A: The suffix variation reflects internal Vishay manufacturing or distribution codes and does not indicate functional or electrical differences. Both suffixes denote the same 75 mOhm ESR specification at 100 kHz.

Q: Are both parts RoHS3 compliant?

A: Yes. Both T54EE157M030CSS075 and T54EE157M030CSA075 are ROHS3 compliant and carry COTS (Commercial Off-The-Shelf) ratings with high reliability designations.

Q: What is the moisture sensitivity level, and how does it affect handling?

A: Both parts have MSL 3 (168 Hours) rating. This indicates standard moisture sensitivity requiring standard PCB assembly handling procedures and storage conditions per IPC standards.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection may be based on current inventory levels, supplier availability, or established procurement preferences. Both offer identical performance and reliability.
