Engineering Selection Recommendations

All four parts—T54EE477M016CSS025, T54EE477M016CSA025, T54EE477M016HSA025, and T54EE477M016LZA025—are electrically and mechanically identical and interchangeable in circuit applications. Selection between these parts is determined by compliance requirements and supply availability.

For applications requiring ROHS3 compliance, select from T54EE477M016CSS025, T54EE477M016CSA025, or T54EE477M016HSA025. The T54EE477M016LZA025 is RoHS non-compliant and is suitable only for applications where RoHS compliance is not mandated.

All parts carry active product status from Vishay Polytech and are rated for COTS (Commercial Off-The-Shelf) applications with high reliability features. Selection among the three ROHS3-compliant options is based on inventory availability and procurement lead times.

Frequently Asked Questions (FAQ)

Q: Are all four parts electrically interchangeable?

A: Yes. T54EE477M016CSS025, T54EE477M016CSA025, T54EE477M016HSA025, and T54EE477M016LZA025 share identical electrical specifications: 470 µF capacitance, 16 V rating, 25 mOhm ESR at 100 kHz, and identical operating temperature range. They are direct substitutes in circuit design.

Q: Can T54EE477M016LZA025 be used in place of T54EE477M016CSS025?

A: Electrical and mechanical substitution is valid. However, T54EE477M016LZA025 is RoHS non-compliant, while T54EE477M016CSS025 is ROHS3 compliant. Use T54EE477M016LZA025 only in applications where RoHS compliance is not required.

Q: Do all parts fit the same PCB footprint?

A: Yes. All four parts use the 2917 (7343 Metric) package with identical dimensions: 0.287" L x 0.169" W (7.30 mm x 4.30 mm) and maximum seated height of 0.169" (4.30 mm). PCB layout and assembly are identical.

Q: What is the difference between the part numbers?

A: The part numbers differ only in internal Vishay Polytech manufacturing codes (CSS, CSA, HSA, LZA). These designations reflect different manufacturing batches or process variations but do not affect electrical performance or mechanical fit.

Q: Are there any temperature or reliability differences?

A: No. All parts operate across -55°C to 125°C and maintain a lifetime rating of 2000 hours at 125°C. Reliability and thermal performance are identical.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All parts are rated MSL 3 with a floor life of 168 hours. Proper storage and handling procedures for MSL 3 components must be followed.
