Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the T97Z476M050ESA are qualified based on the following criteria:

Matching Parameters (Required for Substitution):

• Capacitance: 47 µF
• Voltage Rating: 50 V
• ESR: 240 mOhm
• Package / Case: 3024 (7660 Metric)
• Mounting Type: Surface Mount
• Type: Conformal Coated
• Series: TANTAMOUNT™ T97
• Operating Temperature Range: -55°C to 85°C

Variable Parameter (Allowed Variation):

• Tolerance: ±10% (tighter than the main part's ±20%)

Packaging Format Variation (Allowed):

• Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® formats are interchangeable for the same electrical component

All identified substitutes maintain identical electrical performance and mechanical compatibility while offering tighter tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and are manufactured by Vishay Sprague within the TANTAMOUNT™ T97 series. The primary distinction between the main part and substitutes is tolerance specification: the main part carries ±20% tolerance, while all substitutes offer ±10% tolerance, representing improved capacitance accuracy.

Selection between substitute parts depends on packaging format requirements:

• T97Z476K050ESA and T97Z476K050ESB are supplied in Tape & Reel (TR) format
• T97Z476K050LSA is supplied in Cut Tape (CT) & Digi-Reel® format

All parts share identical electrical characteristics, mechanical dimensions, and environmental ratings. RoHS compliance status is non-compliant for all parts. Moisture Sensitivity Level (MSL) is 2A (4 Weeks) across all variants.

Frequently Asked Questions (FAQ)

Q: Can T97Z476K050ESA, T97Z476K050ESB, or T97Z476K050LSA be used as direct replacements for T97Z476M050ESA?

A: Yes. All three parts are direct substitutes. They maintain identical capacitance (47 µF), voltage rating (50 V), ESR (240 mOhm), package footprint (3024), and operating temperature range (-55°C to 85°C). The substitutes offer tighter tolerance (±10% versus ±20%), which is a performance improvement.

Q: What is the difference between T97Z476K050ESA, T97Z476K050ESB, and T97Z476K050LSA?

A: The electrical specifications are identical. The differences are in packaging format and inventory availability. T97Z476K050ESA and T97Z476K050ESB use Tape & Reel (TR) format, while T97Z476K050LSA uses Cut Tape (CT) & Digi-Reel® format. Select based on your assembly equipment requirements.

Q: Does tolerance difference affect circuit performance?

A: The substitute parts carry ±10% tolerance compared to the main part's ±20%. This represents tighter capacitance accuracy and may improve circuit performance in applications sensitive to capacitance variation. Both tolerance levels are within the same electrical class.

Q: Are all parts in the same package footprint?

A: Yes. All parts use the 3024 (7660 Metric) package with identical dimensions: 0.299" L × 0.236" W (7.60 mm × 6.00 mm) and maximum seated height of 0.252" (6.40 mm). They are mechanically interchangeable on PCBs designed for this footprint.

Q: What packaging format should I select?

A: Choose Tape & Reel (TR) format for high-volume automated assembly. Choose Cut Tape (CT) & Digi-Reel® format for lower volumes or manual assembly processes. The electrical component is identical; only the delivery format differs.
