Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812GC681MATME is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Capacitance value: 680 pF (exact match required)
• Package / Case: 1812 (4532 Metric) (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (minimum requirement)
• Mounting Type: Surface Mount, MLCC (exact match required)

Allowable Variation Parameters:

• Voltage Rating: Equal to or greater than 2000V
• Tolerance: Equal to or tighter than ±20%
• RoHS Status: ROHS3 Compliant or equivalent
• Moisture Sensitivity Level: MSL 1 or better

The substitute part 1812HC681KAT1A meets all mandatory criteria and provides upgraded electrical performance through higher voltage rating (3000V) and improved tolerance (±10%), making it suitable for direct replacement in applications where the original specification can accommodate enhanced ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812GC681MATME and 1812HC681KAT1A maintain Active product status with full ROHS3 compliance and REACH unaffected designation. The substitute part 1812HC681KAT1A provides upgraded electrical specifications through increased voltage rating (3000V versus 2000V) and tighter tolerance (±10% versus ±20%) while maintaining identical footprint dimensions and thermal operating range. Selection between these parts depends on application voltage requirements and tolerance specifications. The substitute part accommodates higher voltage stress conditions and applications requiring improved capacitance stability. Physical board layout compatibility requires verification of the increased thickness specification (0.087" maximum versus 0.071" maximum) to ensure clearance in constrained mounting environments.

Frequently Asked Questions (FAQ)

Q: Can 1812HC681KAT1A replace 1812GC681MATME in all applications?

A: Direct replacement is possible when the application circuit can accommodate the higher voltage rating (3000V) and increased component thickness (0.087" maximum). The identical footprint and thermal characteristics ensure electrical compatibility. Physical clearance verification is required for applications with height constraints.

Q: What is the significance of the tolerance difference between ±20% and ±10%?

A: Tolerance defines the allowable deviation from the nominal 680 pF capacitance value. The substitute part's ±10% tolerance provides tighter capacitance accuracy, resulting in improved circuit performance stability. Applications requiring precise capacitance values benefit from this specification upgrade.

Q: Are both parts suitable for the same temperature range?

A: Yes. Both parts operate across the identical temperature range of -55°C to 125°C with X7R temperature coefficient characteristics, ensuring consistent performance across thermal extremes.

Q: What does the thickness difference mean for PCB assembly?

A: The substitute part has a maximum thickness of 0.087" compared to 0.071" for the main part. This 0.016" difference requires verification in applications with limited vertical clearance above the component or in multi-layer board designs with tight spacing constraints.

Q: Are both parts RoHS compliant?

A: Yes. Both 1812GC681MATME and 1812HC681KAT1A are ROHS3 compliant with REACH unaffected status, meeting environmental and regulatory requirements for commercial and industrial applications.

Q: What packaging format is available for the substitute part?

A: The 1812HC681KAT1A is supplied in Tape & Reel (TR) packaging format, suitable for automated assembly processes.
