Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 08055C501MAT2A is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 500 pF (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Physical dimensions: 0.079" L x 0.049" W (2.01mm x 1.25mm) (exact match required)
• Thickness (Max): 0.037" (0.94mm) (exact match required)

Allowable Variation Parameters:

• Tolerance: May be tighter (lower value) than ±20%
• Voltage - Rated: May be equal or higher than 50V
• Temperature Coefficient: May differ (X7R, C0G/NP0, etc.) based on application requirements
• RoHS and REACH compliance: Must maintain or exceed current compliance level

The two substitute parts listed below maintain identical capacitance, package, and physical dimensions while offering improvements in either voltage rating or tolerance specification.

Parameter Comparison

Engineering Selection Recommendations

08052C501KAT2A Selection Criteria: This substitute provides a 4x voltage rating increase (200V vs. 50V) while maintaining X7R temperature coefficient and improving tolerance to ±10%. All three parts are ROHS3 compliant and REACH unaffected. This part is suitable for applications requiring higher voltage margin or derating considerations. Inventory availability is significantly higher (22,734 units).

08055A501GAT2A Selection Criteria: This substitute maintains the 50V voltage rating while offering superior tolerance specification (±2% vs. ±20%) and C0G/NP0 temperature coefficient. C0G/NP0 provides superior temperature stability compared to X7R. All compliance certifications are maintained. This part is suitable for precision applications requiring tighter capacitance tolerance and minimal temperature-dependent capacitance drift. Inventory availability is high (24,605 units).

Both substitute parts maintain identical physical dimensions, package specifications, and mounting characteristics, ensuring direct PCB compatibility with the original 08055C501MAT2A design.

Frequently Asked Questions (FAQ)

Q: Can 08052C501KAT2A replace 08055C501MAT2A in my circuit? A: Yes. Both parts share identical 500 pF capacitance, 0805 package dimensions, and surface mount characteristics. The 08052C501KAT2A provides higher voltage rating (200V vs. 50V) and tighter tolerance (±10% vs. ±20%), making it a direct electrical and mechanical substitute. Temperature coefficient remains X7R.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients? A: X7R (08055C501MAT2A and 08052C501KAT2A) provides ±15% capacitance change across the -55°C to 125°C operating range. C0G/NP0 (08055A501GAT2A) provides superior stability with minimal capacitance drift across temperature. Selection depends on application sensitivity to temperature-induced capacitance variation.

Q: Why would I choose the ±20% tolerance part over ±10% or ±2%? A: Applications with loose capacitance requirements may select ±20% tolerance parts for cost optimization. However, both substitute parts offer improved tolerance specifications while maintaining identical capacitance value and package form factor.

Q: Are all three parts PCB-compatible? A: Yes. All three parts use identical 0805 (2012 Metric) package dimensions (0.079" L x 0.049" W, 0.037" max thickness) and surface mount mounting type. Direct PCB footprint compatibility is guaranteed.

Q: Do all parts meet the same compliance requirements? A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity level rating. Compliance certifications are equivalent across all options.

Q: Which substitute should I select for a high-reliability application? A: Selection depends on specific circuit requirements. For voltage margin: 08052C501KAT2A (200V rating). For tolerance and temperature stability: 08055A501GAT2A (±2% tolerance, C0G/NP0 coefficient). Both maintain active product status and full compliance certifications.
