Frequently Asked Questions (FAQ)
Q: What electrical parameters must remain identical for a part to be considered a direct substitute?
A: Direct substitutes must maintain the following electrical parameters: 3 pF capacitance, ±0.25pF tolerance, 50V voltage rating, and C0G/NP0 temperature coefficient. The operating temperature range must remain -55°C to 125°C.
Q: Are all substitute parts mechanically compatible with the original MBASU105SCG030CFNA01?
A: Yes. All substitute parts use the 0402 (1005 Metric) package with identical physical dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm) and maximum thickness (0.022" / 0.55mm). They are surface mount MLCCs with identical mounting characteristics.
Q: What is the difference between upgrade parts and parametric equivalents?
A: Upgrade parts (AC0402CRNPO9BN3R0, GCM1555C1H3R0CA16D, GCQ1555C1H3R0CB01D) carry AEC-Q200 automotive qualification, making them suitable for automotive applications. Parametric equivalents maintain identical electrical and mechanical specifications but are designated for general purpose applications unless otherwise specified.
Q: Can I use C1005C0G1H030C050BA (TDK) in a new design?
