Substitute Part Grouping Explanation

The 1812GC272KAT1A is identified as an upgrade substitute for the 1812SC272MAT1A. Substitution is valid based on the following criteria:

Matching Parameters:

• Capacitance: 2700 pF (identical)
• Temperature Coefficient: X7R (identical)
• Operating Temperature Range: -55°C ~ 125°C (identical)
• Package / Case: 1812 (4532 Metric) (identical)
• Physical Dimensions: 0.181" L x 0.126" W, 4.60mm x 3.20mm (identical)
• Thickness: 0.071" (1.80mm) (identical)
• Mounting Type: Surface Mount, MLCC (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

Upgrade Characteristics:

• Voltage Rating: 2000V (2kV) vs. 1500V (1.5kV) — higher voltage rating
• Tolerance: ±10% vs. ±20% — tighter tolerance specification

The 1812GC272KAT1A provides enhanced electrical performance through increased voltage margin and improved capacitance tolerance, making it suitable for applications requiring higher reliability or stricter tolerance requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812SC272MAT1A and 1812GC272KAT1A are active production parts with ROHS3 compliance and REACH unaffected status. The 1812GC272KAT1A is suitable as a direct substitute where higher voltage rating (2000V vs. 1500V) and tighter tolerance (±10% vs. ±20%) provide design margin benefits. Selection between these parts depends on circuit voltage requirements and tolerance specifications. Both parts maintain identical physical footprint, thermal characteristics, and moisture sensitivity rating, ensuring PCB layout compatibility and assembly process compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 1812GC272KAT1A replace the 1812SC272MAT1A in existing designs?

A: Yes. The 1812GC272KAT1A is a direct substitute with identical capacitance, package dimensions, and thermal characteristics. The higher voltage rating (2kV vs. 1.5kV) and tighter tolerance (±10% vs. ±20%) make it suitable for applications requiring enhanced performance margins.

Q: Are there any PCB layout or assembly differences between these parts?

A: No. Both parts use identical 1812 (4532 Metric) package dimensions (0.181" L x 0.126" W, 4.60mm x 3.20mm) and 0.071" (1.80mm) maximum thickness. PCB footprints, reflow profiles, and assembly processes are interchangeable.

Q: What is the significance of the tolerance difference (±20% vs. ±10%)?

A: The 1812GC272KAT1A provides tighter capacitance tolerance (±10%), resulting in more predictable circuit performance. The 1812SC272MAT1A with ±20% tolerance allows wider capacitance variation. Selection depends on circuit sensitivity to capacitance drift.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Storage, handling, and reflow processes are identical for both parts.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1812SC272MAT1A and 1812GC272KAT1A are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements.
