Substitute Part Grouping Explanation

Substitution eligibility for the 1812GC332MAT3A is determined by the following criteria:

• Identical capacitance value: 3300 pF
• Identical package footprint: 1812 (4532 Metric)
• Identical temperature coefficient: X7R
• Identical mounting type: Surface Mount, MLCC
• Equal or higher voltage rating
• Equal or tighter tolerance
• Active product status
• ROHS3 compliance

The substitute part 1812HC332KAT1A meets all substitution criteria with an upgraded voltage rating of 3000V and improved tolerance of ±10%.

Parameter Comparison

Engineering Selection Recommendations

The 1812HC332KAT1A qualifies as a direct substitute for the 1812GC332MAT3A based on maintained electrical specifications and regulatory compliance. Both components are Active products with ROHS3 compliance and REACH Unaffected status. The substitute part provides enhanced voltage margin (3000V versus 2000V) and improved capacitance tolerance (±10% versus ±20%) within the same 1812 package footprint. Physical thickness increases from 2.20mm to 2.80mm; PCB layout clearance must be verified for applications with height constraints.

Frequently Asked Questions (FAQ)

Q: Can 1812HC332KAT1A replace 1812GC332MAT3A in all applications?

A: Yes, provided PCB layout accommodates the increased thickness of 2.80mm maximum. The substitute part maintains identical capacitance, temperature coefficient, operating temperature range, and package footprint while offering higher voltage rating and tighter tolerance.

Q: What is the primary difference between these two parts?

A: The main differences are voltage rating (2000V versus 3000V), tolerance (±20% versus ±10%), and maximum thickness (2.20mm versus 2.80mm). Capacitance value and all other electrical parameters remain identical.

Q: Are both parts suitable for high-voltage applications?

A: Both parts are rated for high-voltage operation. The 1812GC332MAT3A is rated for 2000V, while the 1812HC332KAT1A is rated for 3000V. Selection depends on circuit voltage requirements.

Q: Do these parts have identical moisture sensitivity?

A: Yes. Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and classified as Active products with identical regulatory status.
