Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MBASU105SB5102MFNA01 is determined by strict equivalence across the following parameters:

Critical Electrical Parameters:

• Capacitance: 1000 pF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 50V (exact match required)
• Temperature Coefficient: X5R (exact match required)
• Operating Temperature: -55°C ~ 85°C (exact match required)

Critical Mechanical Parameters:

• Package / Case: 0402 (1005 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Size / Dimension: 0.039" L x 0.020" W (1.00mm x 0.50mm) (exact match required)
• Thickness (Max): 0.022" (0.55mm) (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All substitute parts listed meet these criteria and are therefore electrically and mechanically interchangeable with the main part number.
