Substitute Part Grouping Explanation

Substitution eligibility for the T496X475K050AS is determined by strict equivalence across the following parameters:

• Capacitance Value: 4.7 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating: 50 V (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Type: Molded Tantalum (exact match required)

The substitute part T496X475K050ATE1K5 meets all these criteria. This part belongs to the same T496 series and maintains identical electrical and mechanical specifications. The primary distinction is product status: T496X475K050ATE1K5 is active in production, whereas T496X475K050AS is obsolete.
