Substitute Part Grouping Explanation

Substitution eligibility for the C1808C331MGRAC7800 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Capacitance value: 330 pF (exact match required)
• Package / Case: 1808 (4520 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: Equal to or greater than 2000V
• Temperature Coefficient: X7R or C0G/NP0 (both acceptable for general-purpose applications)
• Tolerance: ±20% or tighter (±5% acceptable as upgrade)

The substitute part C1808C331JZGAC7800 meets all mandatory criteria and provides enhanced electrical performance through higher voltage rating (2500V) and improved tolerance specification (±5%).

Parameter Comparison

Engineering Selection Recommendations

C1808C331MGRAC7800 (Main Part): Select this part for applications requiring standard X7R temperature coefficient performance with 2000V voltage rating. Active product status ensures continued manufacturing support and availability. ROHS3 compliance and unlimited MSL rating provide regulatory flexibility for diverse deployment environments.

C1808C331JZGAC7800 (Substitute Part): Select this part as a direct substitute when enhanced electrical performance is required. The upgrade provides 500V additional voltage margin (2500V rating versus 2000V), tighter capacitance tolerance (±5% versus ±20%), and C0G/NP0 temperature coefficient for improved stability across temperature extremes. Both parts share identical package dimensions, mounting characteristics, and regulatory compliance status. Active product status confirms manufacturing continuity.

Both parts are manufactured by KEMET, carry Active product status, maintain ROHS3 compliance, and feature unlimited moisture sensitivity rating (MSL 1). Selection between these parts depends on circuit voltage margin requirements and capacitance tolerance specifications.

Frequently Asked Questions (FAQ)

Q: Can C1808C331JZGAC7800 be used as a direct replacement for C1808C331MGRAC7800?

A: Yes. Both parts share identical capacitance (330 pF), package dimensions (1808/4520 Metric), mounting type (Surface Mount MLCC), operating temperature range (-55°C ~ 125°C), and regulatory compliance (ROHS3, REACH Unaffected, MSL 1). The substitute provides higher voltage rating (2500V versus 2000V) and tighter tolerance (±5% versus ±20%), making it functionally compatible and electrically superior.

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

A: Both temperature coefficients are provided in the part specifications. X7R (main part) and C0G/NP0 (substitute part) are both acceptable for general-purpose applications. Selection depends on circuit requirements for temperature stability characteristics across the -55°C ~ 125°C operating range.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 1808 (4520 Metric) package with dimensions of 0.185" L x 0.079" W (4.70mm x 2.00mm) and maximum thickness of 0.085" (2.15mm). PCB layout and assembly tooling require no modification when substituting between these parts.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. Both parts can be stored and handled without time-sensitive moisture precautions, simplifying inventory management and reducing preparation time before assembly.

Q: Are both parts currently in active production?

A: Yes. Both C1808C331MGRAC7800 and C1808C331JZGAC7800 carry Active product status, confirming ongoing manufacturing support and availability from KEMET.
