Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Compatibility Requirements:

• Identical capacitance value: 330 pF
• Identical package format: 0805 (2012 Metric)
• Identical mounting type: Surface Mount, MLCC
• Identical operating temperature range: -55°C ~ 125°C
• Identical moisture sensitivity level: 1 (Unlimited)
• Identical RoHS compliance: ROHS3 Compliant

Allowable Parameter Variations:

• Voltage rating: Equal to or greater than 50V
• Tolerance: Equal to or tighter than ±20%
• Temperature coefficient: X7R or C0G/NP0 (both acceptable for this application category)
• Thickness: Variations within mechanical constraints

The substitute parts listed below meet all primary compatibility requirements and represent improvements or equivalent alternatives in tolerance and voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance.

0805Y1000331JCT (Knowles Syfer): Provides doubled voltage rating (100V vs. 50V) with improved tolerance (±5% vs. ±20%) and C0G/NP0 temperature coefficient. Suitable for applications requiring higher voltage margin or superior temperature stability.

C0805X331J5RAC7800 (KEMET): Maintains 50V voltage rating with improved tolerance (±5% vs. ±20%) and X7R temperature coefficient. Offers reduced thickness (0.035" vs. 0.051"), beneficial for space-constrained designs.

C0805X331K5RAC7800 (KEMET): Maintains 50V voltage rating with moderate tolerance improvement (±10% vs. ±20%) and X7R temperature coefficient. Reduced thickness (0.039" vs. 0.051") provides layout flexibility.

C0805X331J5GAC7800 (KEMET): Maintains 50V voltage rating with improved tolerance (±5% vs. ±20%) and C0G/NP0 temperature coefficient. Includes low ESL feature with reduced thickness (0.035" vs. 0.051"), suitable for high-frequency applications.

Frequently Asked Questions (FAQ)

Q: Can 0805Y1000331JCT be used as a direct replacement for 0805Y0500331MXT?

A: Yes. The 100V rating is compatible with 50V circuit requirements. The improved tolerance (±5%) and C0G/NP0 temperature coefficient provide enhanced performance characteristics. All package and mounting specifications are identical.

Q: What is the primary difference between KEMET C0805X and Knowles Syfer 0805Y series?

A: Both series maintain identical capacitance, package format, and operating temperature range. Differences exist in thickness, tolerance ratings, and temperature coefficient options. Selection depends on specific circuit requirements for voltage margin, tolerance precision, and thermal stability.

Q: Are the KEMET C0805X331J5RAC7800 and C0805X331J5GAC7800 interchangeable?

A: Both parts share identical electrical specifications (330 pF, 50V, ±5% tolerance, 0.035" thickness). The primary difference is temperature coefficient: X7R versus C0G/NP0. C0G/NP0 provides superior temperature stability and lower ESL. Selection depends on application requirements for temperature coefficient performance.

Q: Does reduced thickness affect PCB layout or assembly?

A: Reduced thickness (0.035" to 0.039" versus 0.051") does not affect electrical compatibility. Layout and assembly processes remain unchanged for 0805 package format. Thinner components may provide marginal benefits in space-constrained designs but do not alter functional performance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory conformance and handling compatibility with the original part.
