Substitute Part Grouping Explanation

Substitution eligibility for the 1812GC100KAT1A is determined by the following criteria:

Primary Substitution Parameters:

• Capacitance value: 10 pF (exact match required)
• Package / Case: 1812 (4532 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (minimum requirement)
• RoHS Status: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (minimum requirement)

Allowable Variations:

• Voltage - Rated: Equal to or greater than 2000V
• Temperature Coefficient: C0G/NP0 or X7R (both acceptable for general-purpose applications)
• Tolerance: ±5% or ±10% (tighter tolerance acceptable)

The substitute part 1812HA100JAT1A meets all primary substitution parameters and provides an upgrade in rated voltage (3000V vs. 2000V) and tolerance (±5% vs. ±10%) while maintaining identical package dimensions and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812GC100KAT1A and 1812HA100JAT1A are Active products with ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component procurement.

The 1812HA100JAT1A substitute provides performance advantages including higher rated voltage (3000V vs. 2000V) and improved tolerance (±5% vs. ±10%) within an identical footprint. The reduced thickness (0.057" vs. 0.071") offers additional design flexibility for space-constrained applications.

Selection between these parts should be based on circuit voltage requirements and tolerance specifications. The main part 1812GC100KAT1A is suitable for applications requiring 2000V operation with standard tolerance. The substitute 1812HA100JAT1A is appropriate for applications requiring higher voltage margin or tighter capacitance tolerance.

Frequently Asked Questions (FAQ)

Q: Can 1812HA100JAT1A replace 1812GC100KAT1A in all applications?

A: Yes, within the constraints of circuit design. The substitute part maintains identical capacitance (10 pF), package dimensions (1812 / 4532 Metric), and operating temperature range (-55°C ~ 125°C). The higher rated voltage (3000V vs. 2000V) and improved tolerance (±5% vs. ±10%) are compatible with applications designed for the original part.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients?

A: Both temperature coefficients are provided in the parameter specifications. X7R exhibits ±15% capacitance change over the operating temperature range. C0G/NP0 exhibits minimal capacitance change (±30 ppm/°C) over the same range. Selection depends on circuit requirements for temperature stability.

Q: Are the physical dimensions identical between these parts?

A: The length and width are identical (0.181" L x 0.126" W / 4.60mm x 3.20mm). The thickness differs: 1812GC100KAT1A is 0.071" (1.80mm) maximum, while 1812HA100JAT1A is 0.057" (1.45mm) maximum. Both fit the 1812 (4532 Metric) package classification.

Q: What is the moisture sensitivity level for these parts?

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

Q: Are both parts RoHS compliant?

A: Yes, both 1812GC100KAT1A and 1812HA100JAT1A are ROHS3 compliant and REACH Unaffected, meeting current regulatory standards for electronic component procurement.
