Substitute Part Grouping Explanation

Substitution of the 1808SA221MAT1A is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Capacitance value: 220 pF (exact match required)
• Temperature coefficient: C0G/NP0 (ensures stable performance across operating temperature range)
• Package / Case: 1808 (4520 Metric) (ensures mechanical and electrical compatibility)
• Mounting type: Surface Mount, MLCC (maintains assembly compatibility)
• Physical dimensions: 0.181" L x 0.079" W (4.60mm x 2.00mm) with maximum thickness of 0.087" (2.20mm)

Secondary Substitution Parameters:

• Voltage rating: Equal to or greater than 1500V (1.5kV)
• Tolerance: Equal to or tighter than ±20%
• Operating temperature range: Must encompass -55°C ~ 125°C
• Compliance: ROHS3 compliant, MSL 1 rating

The substitute part 1808GA221JAT1A meets all primary criteria and provides improved performance through higher voltage rating (2000V) and tighter tolerance (±5%).

Parameter Comparison

Engineering Selection Recommendations

Both the 1808SA221MAT1A and 1808GA221JAT1A are active production parts with ROHS3 compliance and MSL 1 rating, ensuring regulatory compliance and handling flexibility. The 1808GA221JAT1A provides an upgrade path with higher voltage rating (2000V versus 1500V) and improved tolerance specification (±5% versus ±20%), while maintaining identical physical dimensions, temperature coefficient, and operating temperature range. Selection between these parts depends on circuit voltage requirements and tolerance specifications. Both parts are suitable for general-purpose applications requiring stable capacitance performance across the -55°C to 125°C operating range.

Frequently Asked Questions (FAQ)

Q: Can the 1808GA221JAT1A directly replace the 1808SA221MAT1A in existing designs?

A: Yes. Both parts share identical capacitance (220 pF), temperature coefficient (C0G/NP0), package (1808 / 4520 Metric), physical dimensions (0.181" L x 0.079" W, 0.087" max thickness), and operating temperature range (-55°C ~ 125°C). The substitute part provides higher voltage rating and tighter tolerance, making it functionally compatible for direct substitution.

Q: What are the key differences between these two parts?

A: The primary differences are voltage rating (1808SA221MAT1A: 1500V; 1808GA221JAT1A: 2000V) and tolerance specification (1808SA221MAT1A: ±20%; 1808GA221JAT1A: ±5%). All other electrical and mechanical parameters remain identical.

Q: Are there any packaging differences between these parts?

A: The 1808SA221MAT1A is specified with standard packaging, while the 1808GA221JAT1A is supplied in Tape & Reel (TR) format. Both use the same 1808 (4520 Metric) package case with identical physical dimensions and mounting characteristics.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 1808SA221MAT1A and 1808GA221JAT1A are ROHS3 compliant, REACH unaffected, with MSL 1 (unlimited moisture sensitivity) rating and EAR99 export classification.

Q: Which part should be selected for new designs?

A: Selection depends on circuit voltage requirements. For applications operating at or below 1500V, either part is suitable. For applications requiring higher voltage margin or improved tolerance performance, the 1808GA221JAT1A is the appropriate choice.
