Key Parameters

Substitute Part Grouping Explanation

Substitution of the TCOB0J476M8R is determined by strict equivalence across the following parameters:

• Capacitance value: 47 µF (exact match required)
• Voltage rating: 6.3 V (exact match required)
• ESR specification: 150 mOhm @ 100kHz (exact match required)
• Package / Case: 1411 (3528 Metric) (exact match required)
• Tolerance: ±20% (exact match required)
• Operating temperature range: -55°C to 105°C (exact match required)
• Mounting type: Surface Mount (exact match required)

The substitute part T55B476M6R3C0150 from Vishay Sprague meets all these criteria and is classified as a parametric equivalent. This part maintains identical electrical and mechanical specifications while offering active product status and improved availability.
