Substitute Part Grouping Explanation

Substitution of the T54EE227M016CSS025 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 220 µF (exact match required)
• Voltage rating: 16 V (exact match required)
• ESR specification: 25 mOhm @ 100kHz (exact match required)
• Tolerance: ±20% (exact match required)

Mechanical Parameters:

• Package designation: 2917 (7343 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Physical dimensions: 0.287" L x 0.169" W (7.30mm x 4.30mm) (exact match required)

Environmental & Compliance Parameters:

• Operating temperature range: -55°C to 125°C (exact match required)
• Lifetime specification: 2000 Hrs @ 125°C (exact match required)
• RoHS compliance: ROHS3 (exact match required)
• Moisture sensitivity level: MSL 3 (168 Hours) (exact match required)

The substitute part T54EE227M016CSA025 meets all these criteria and is therefore classified as a parametric equivalent.

Parameter Comparison

The choice between these part numbers does not affect circuit performance, thermal characteristics, or compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can T54EE227M016CSA025 be used as a direct replacement for T54EE227M016CSS025?

A: Yes. Both parts are parametric equivalents with identical capacitance (220 µF), voltage rating (16 V), ESR (25 mOhm @ 100kHz), package dimensions (2917/7343 Metric), operating temperature range (-55°C to 125°C), and lifetime specifications (2000 Hrs @ 125°C). No circuit modifications are required.

Q: Are there any differences in the physical footprint between these two parts?

A: No. Both parts have identical dimensions of 0.287" L x 0.169" W (7.30mm x 4.30mm) with a maximum seated height of 0.169" (4.30mm). PCB layout and assembly tooling remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both T54EE227M016CSS025 and T54EE227M016CSA025 are ROHS3 compliant with MSL 3 (168 Hours) moisture sensitivity rating. Both carry COTS ratings and high reliability designations.

Q: What is the difference between the part numbers CSS025 and CSA025?

A: The difference in the suffix (CSS versus CSA) indicates a variation in packaging or manufacturing process within the same electrical and mechanical specification class. Both parts are functionally equivalent for circuit applications.

Q: Can these parts be used interchangeably in high-reliability applications?

A: Yes. Both parts are rated for high reliability with identical lifetime specifications of 2000 hours at 125°C and active product status. They are suitable for equivalent use in high-reliability circuit designs.
