Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the C1206C331MGRAC7800 is based on the following critical parameters that must remain constant or improve:

Mandatory Matching Parameters:

• Capacitance value: 330 pF (exact match required)
• Voltage rating: 2000V minimum (no reduction permitted)
• Temperature coefficient: X7R (ensures equivalent temperature stability)
• Package format: 1206 (3216 Metric) (PCB footprint compatibility)
• Mounting type: Surface Mount, MLCC (assembly process compatibility)

Allowable Variation Parameters:

• Tolerance: May improve from ±20% to ±10% (tighter tolerance is acceptable)
• Physical dimensions: Minor variations within package class are acceptable if footprint compatibility is maintained
• Manufacturer: Different manufacturers permitted if all electrical and mechanical specifications align

The substitute part KGM31AR73D331KU from KYOCERA AVX meets all mandatory matching criteria and provides improved tolerance specification (±10% versus ±20%), making it a direct functional equivalent with enhanced precision characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: C1206C331MGRAC7800 (KEMET)

Use the primary part when:

• KEMET component qualification is specified in design documentation
• Existing inventory of 966 units is available for immediate procurement
• Design tolerance of ±20% meets circuit requirements
• Supply chain preference favors KEMET sourcing

Substitute Part Selection: KGM31AR73D331KU (KYOCERA AVX)

Use the substitute part when:

• Primary part inventory is depleted or unavailable
• Circuit design benefits from improved ±10% tolerance specification
• KYOCERA AVX components are qualified in the design or procurement system
• Larger available inventory (12,924 units) supports production scheduling
• Both parts maintain identical ROHS3 compliance and REACH unaffected status

Both parts are Active in product status and carry equivalent regulatory certifications (ROHS3 Compliant, REACH Unaffected, EAR99 ECCN classification). Physical dimension variations (length 3.20mm vs 3.30mm, thickness 1.75mm vs 1.80mm) remain within standard 1206 package tolerances and do not affect PCB footprint compatibility or assembly processes.

Frequently Asked Questions (FAQ)

Q: Can KGM31AR73D331KU be used as a direct replacement for C1206C331MGRAC7800 on existing PCBs?

A: Yes. Both parts use identical 1206 (3216 Metric) package format with compatible physical dimensions. The substitute part's length of 3.30mm and thickness of 1.80mm fall within acceptable tolerances for the 1206 package class and will not cause assembly or placement issues.

Q: What is the difference in tolerance between these two parts?

A: The primary part C1206C331MGRAC7800 has ±20% tolerance, while the substitute KGM31AR73D331KU has ±10% tolerance. The substitute provides tighter capacitance accuracy. For circuits requiring specific capacitance values, the ±10% tolerance of the substitute part offers improved precision.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both C1206C331MGRAC7800 and KGM31AR73D331KU are ROHS3 Compliant and REACH Unaffected. Both carry EAR99 ECCN classification and identical HTSUS code 8532.24.0020.

Q: Do these parts have different moisture sensitivity levels?

A: No. Both parts have MSL Rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: What are the critical parameters that must match for substitution?

A: Capacitance (330 pF), voltage rating (2000V), temperature coefficient (X7R), package format (1206), and mounting type (Surface Mount MLCC) must remain identical. These parameters determine electrical function and physical compatibility.

Q: Can either part be used in high-temperature applications?

A: Yes. Both parts operate across the identical temperature range of -55°C to 125°C with X7R temperature coefficient, ensuring stable capacitance performance throughout this range.

Q: Is there a performance difference between KEMET and KYOCERA AVX versions?

A: Both parts meet identical electrical specifications for capacitance, voltage, and temperature performance. The primary difference is tolerance specification (±20% vs ±10%), with the KYOCERA AVX part offering improved precision.
