Substitute Part Grouping Explanation
Substitute parts are classified into two categories based on their relationship to the main part:
Upgrade Substitutes are components that maintain all critical electrical parameters (capacitance, voltage rating, temperature coefficient, tolerance) and mechanical compatibility (1206 package, surface mount) while offering enhanced certifications, features, or application-specific ratings. These parts are direct functional replacements with additional qualifications.
Parametric Equivalents are components that match all electrical specifications and package dimensions but may differ in packaging format (Tape & Reel versus Cut Tape & Digi-Reel) or originate from different manufacturers. These parts satisfy identical circuit requirements and are interchangeable at the board level.
Substitution eligibility is determined by the following parameters:
- Capacitance value: 4.7 µF (exact match required)
- Voltage rating: 50V (exact match required)
- Temperature coefficient: X7R (exact match required)
- Tolerance: ±10% (exact match required)
- Package: 1206 (3216 Metric) (exact match required)
- Operating temperature: -55°C ~ 125°C (exact match required)
- Mounting type: Surface Mount, MLCC (exact match required)
- RoHS compliance: ROHS3 (exact match required)
- MSL rating: 1 (Unlimited) (exact match required)
