Electrical Parameters (Must Match Exactly):

• Capacitance: 47 µF
• Tolerance: ±10%
• Voltage Rating: 50 V
• Type: Conformal Coated
• ESR: 240 mOhm
• Operating Temperature Range: -55°C to 85°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: 3024 (7660 Metric)
• Mounting Type: Surface Mount
• Size / Dimension: 0.299" L x 0.236" W (7.60 mm x 6.00 mm)
• Height - Seated (Max): 0.252" (6.40 mm)
• Manufacturer Size Code: Z

Allowed Variation:

• Packaging format (Tape & Reel vs. Cut Tape & Digi-Reel®)
• Compliance certifications (RoHS status, REACH status)

All substitute parts listed maintain identical electrical performance and physical footprint compatibility with the main part number.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed—T97Z476K050ESA, T97Z476K050ESB, and T97Z476K050LSA—are direct electrical and mechanical equivalents to the T97Z476K050ESS. Selection among these parts should be based on the following factors:

Packaging Format Consideration: T97Z476K050ESS, T97Z476K050ESA, and T97Z476K050ESB are supplied in Tape & Reel (TR) format. T97Z476K050LSA is supplied in Cut Tape (CT) & Digi-Reel® format. Choose based on assembly line requirements and tape handling equipment compatibility.

Compliance and Regulatory Status: All parts maintain identical RoHS non-compliant status and EAR99 ECCN classification. T97Z476K050ESA and T97Z476K050ESB are REACH Unaffected. T97Z476K050LSA is REACH Affected. Compliance requirements for your application determine which part is appropriate.

Inventory and Availability: T97Z476K050ESB has the highest inventory level (9,288 pcs), followed by T97Z476K050ESA (2,076 pcs), T97Z476K050LSA (1,354 pcs), and T97Z476K050ESS (849 pcs). Availability may influence selection for high-volume production or urgent requirements.

All parts are Active product status from Vishay Sprague and maintain identical electrical performance, thermal characteristics, and physical dimensions.

Frequently Asked Questions (FAQ)

Q: Can T97Z476K050ESA, T97Z476K050ESB, and T97Z476K050LSA be used interchangeably with T97Z476K050ESS on the same PCB?

A: Yes. All substitute parts maintain identical electrical parameters (47 µF, ±10%, 50 V, 240 mOhm ESR) and mechanical dimensions (3024 package, 0.299" L x 0.236" W, 0.252" max height). They are direct pin-for-pin and footprint-compatible replacements.

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

A: Tape & Reel (TR) is continuous reel packaging suitable for automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® is pre-cut tape format. Selection depends on your assembly equipment and handling procedures. Both formats contain identical components.

Q: Are there differences in reliability or performance between these substitute parts?

A: No. All parts are from the same TANTAMOUNT™ T97 series, share identical electrical specifications, operating temperature range (-55°C to 85°C), and high reliability features. Performance is equivalent across all listed substitutes.

Q: What does REACH Affected vs. REACH Unaffected mean?

A: REACH Affected indicates the part may contain substances of concern under EU REACH regulations. REACH Unaffected indicates no such substances are present. Selection depends on your regulatory requirements and end-market destination.

Q: Can I substitute T97Z476K050LSA for T97Z476K050ESS in high-volume production?

A: Yes, electrically and mechanically. However, verify that your assembly line equipment supports Cut Tape (CT) & Digi-Reel® format. Tape format compatibility with your pick-and-place machinery is the primary consideration.

Q: Are all substitute parts currently in active production?

A: Yes. All listed parts—T97Z476K050ESS, T97Z476K050ESA, T97Z476K050ESB, and T97Z476K050LSA—maintain Active product status from Vishay Sprague.
