Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812SC332MAT3A is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Capacitance value: 3300 pF (exact match required)
• Temperature coefficient: X7R (maintains stable capacitance across operating temperature range)
• Package / Case: 1812 (4532 Metric) (ensures PCB footprint compatibility)
• Mounting type: Surface Mount, MLCC (maintains assembly process compatibility)
• Operating temperature range: -55°C ~ 125°C (minimum requirement)

Allowable Variation Parameters:

• Voltage rating: May be equal to or higher than 1500V (higher voltage rating provides design margin)
• Tolerance: May be tighter (±10% or better) than ±20% (improved tolerance is acceptable)
• Physical thickness: May vary within assembly clearance limits

The identified substitute part 1812HC332KAT1A meets all mandatory criteria while offering upgraded voltage rating (3000V) and improved tolerance (±10%), making it suitable for applications requiring enhanced performance margins.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812SC332MAT3A and 1812HC332KAT1A are active production parts manufactured by KYOCERA AVX with full ROHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts depends on circuit voltage requirements and tolerance specifications.

The 1812SC332MAT3A is the primary selection for applications with 1500V maximum voltage requirements and where ±20% tolerance is acceptable. The 1812HC332KAT1A serves as a direct substitute for designs requiring higher voltage margin (3000V rating) or tighter capacitance tolerance (±10%). The substitute part's increased thickness (0.110" vs. 0.087") must be verified against PCB assembly clearance specifications before implementation.

Frequently Asked Questions (FAQ)

Q: Can 1812HC332KAT1A replace 1812SC332MAT3A in all applications?

A: Direct substitution is possible when circuit design permits the increased physical thickness (0.110" vs. 0.087") and when PCB assembly clearance accommodates this dimension. The higher voltage rating (3000V) and improved tolerance (±10%) are compatible with any application designed for the original part's 1500V / ±20% specifications.

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

A: The substitute part offers doubled voltage rating (3000V vs. 1500V) and half the tolerance band (±10% vs. ±20%), with a corresponding increase in physical thickness of 0.023" (0.60mm).

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

A: Yes. The 1812SC332MAT3A is rated for 1500V applications. The 1812HC332KAT1A extends this capability to 3000V applications. Both maintain X7R temperature stability across -55°C to 125°C operating range.

Q: Do these parts have identical PCB footprints?

A: Both parts use the 1812 (4532 Metric) package with identical length (0.181") and width (0.126") dimensions. The thickness difference (0.087" vs. 0.110") does not affect footprint but must be considered for vertical clearance in assembly.

Q: Are both parts RoHS compliant?

A: Yes. Both 1812SC332MAT3A and 1812HC332KAT1A are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).
