Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1812SC392MATME is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Capacitance value: 3900 pF (exact match required)
• Package / Case: 1812 (4532 Metric) (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)

Allowable Variation Parameters:

• Tolerance: May vary (±20% or tighter)
• Voltage - Rated: May be equal or higher
• Physical dimensions: May vary within package specification limits
• Packaging format: May differ (bulk, tape & reel, etc.)

The identified substitute part 1812HC392KAT1A maintains all mandatory compatibility criteria while offering an upgraded voltage rating (3000V vs. 1500V) and improved tolerance (±10% vs. ±20%).

Parameter Comparison

Engineering Selection Recommendations

Both the 1812SC392MATME and 1812HC392KAT1A are active production parts manufactured by KYOCERA AVX with ROHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts is based on application voltage requirements and tolerance specifications:

• 1812SC392MATME is suitable for applications with maximum operating voltage of 1500V and tolerance requirements of ±20%.
• 1812HC392KAT1A is suitable for applications requiring higher voltage margin (3000V rating) or tighter capacitance tolerance (±10%). The increased thickness (2.80mm vs. 2.20mm) must be verified for PCB layout compatibility.

Both parts maintain identical electrical performance characteristics across the -55°C to 125°C operating temperature range with X7R temperature coefficient stability.

Frequently Asked Questions (FAQ)

Q: Can 1812HC392KAT1A replace 1812SC392MATME in all applications?

A: Yes, provided PCB layout accommodates the increased thickness of 2.80mm (vs. 2.20mm). The higher voltage rating and tighter tolerance of 1812HC392KAT1A are backward-compatible with designs specified for 1812SC392MATME.

Q: What is the significance of the X7R temperature coefficient?

A: X7R indicates capacitance variation of ±15% across the -55°C to 125°C operating temperature range. This specification is identical for both parts and ensures stable performance in temperature-sensitive applications.

Q: Are there differences in packaging between these parts?

A: 1812SC392MATME is available in standard packaging, while 1812HC392KAT1A is specified as Tape & Reel (TR). Both use identical 1812 (4532 Metric) surface-mount package format.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and does not require special moisture-control storage or handling procedures prior to soldering.

Q: Can these parts be used interchangeably on the same PCB?

A: Electrical interchangeability is confirmed. Physical interchangeability requires verification that PCB layout accommodates the maximum thickness of 2.80mm for 1812HC392KAT1A.
