Engineering Selection Recommendations

All listed substitute parts maintain identical electrical performance and mechanical compatibility with the T97Z476K050LSB. Selection between equivalent parts should be based on:

Packaging Format Availability: T97Z476K050ESA, T97Z476K050ESB, and T97Z476K050LSB are supplied in Tape & Reel (TR) format. T97Z476K050LSA is supplied in Cut Tape (CT) & Digi-Reel® format. Choose based on assembly line requirements and minimum order quantities.

Inventory Considerations: T97Z476K050ESB offers the highest inventory level (9288 Pcs), followed by T97Z476K050ESA (2076 Pcs), T97Z476K050LSA (1354 Pcs), and T97Z476K050LSB (1127 Pcs).

Compliance Status: All parts are RoHS non-compliant and carry identical ECCN (EAR99) and HTSUS (8532.21.0050) classifications. T97Z476K050ESA and T97Z476K050ESB list REACH Unaffected status, while T97Z476K050LSA lists REACH Affected status.

Moisture Sensitivity: All parts maintain MSL 2A (4 Weeks) rating, requiring identical handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can T97Z476K050ESA, T97Z476K050ESB, and T97Z476K050LSA be used interchangeably with T97Z476K050LSB?

A: Yes. All parts share identical electrical specifications (47 µF, ±10%, 50 V, 240 mOhm ESR), operating temperature range (-55°C to 85°C), and mechanical dimensions (3024 package, 0.299" L x 0.236" W, 0.252" max height). Direct substitution is supported at the circuit level.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging?

A: Packaging format affects distribution and assembly handling only. Tape & Reel (TR) is supplied on continuous reels for automated pick-and-place equipment. Cut Tape (CT) & Digi-Reel® provides smaller quantities on cut tape segments. Component performance and specifications remain identical.

Q: Are there compliance differences between the substitute parts?

A: All parts are RoHS non-compliant with matching ECCN and HTSUS codes. REACH status differs: T97Z476K050ESA and T97Z476K050ESB are REACH Unaffected, while T97Z476K050LSA is REACH Affected. Verify REACH compliance requirements for your application before selection.

Q: Does the conformal coating type differ between parts?

A: All parts are specified as conformal coated tantalum capacitors with identical coating characteristics. No functional differences exist in coating type or performance.

Q: What is the significance of the part number suffix (LSB, ESA, ESB, LSA)?

A: Suffixes indicate packaging format and internal manufacturing designations. LSB and LSA denote one packaging variant, while ESA and ESB denote another. Electrical and mechanical specifications remain constant across all variants.
