Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0805J5000331JAT is determined by strict equivalence across the following parameters:

Capacitance value must be 330 pF with ±5% tolerance. Voltage rating must be 500V or higher. Temperature coefficient must be C0G or NP0 (equivalent designations). Operating temperature range must span -55°C to 125°C. Package must be 0805 (2012 Metric) for mechanical and electrical compatibility. Mounting type must be surface-mount MLCC. AEC-Q200 automotive qualification is required. RoHS3 compliance and MSL 1 rating must be maintained.

The identified substitute part C0805C331JCGACAUTO from KEMET meets all these criteria and is qualified for direct substitution in automotive applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 0805J5000331JAT and C0805C331JCGACAUTO are active production parts with identical electrical specifications and automotive-grade AEC-Q200 certification. The KEMET substitute provides equivalent performance with higher inventory availability (7772 units versus 830 units). Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating. The maximum thickness difference of 0.004" (0.10mm) between parts is within typical PCB assembly tolerances for 0805 packages. Selection between these parts may be based on supply chain availability, lead time, or established vendor relationships, as electrical and mechanical compatibility is fully established.

Frequently Asked Questions (FAQ)

Q: Can C0805C331JCGACAUTO replace 0805J5000331JAT in automotive applications?

A: Yes. Both parts are AEC-Q200 qualified with identical capacitance (330 pF), tolerance (±5%), voltage rating (500V), temperature coefficient (C0G/NP0), and operating temperature range (-55°C to 125°C). Package dimensions and mounting type are equivalent.

Q: Are there physical compatibility concerns between these parts?

A: Both parts use the 0805 (2012 Metric) package with identical length and width (0.079" x 0.049"). The KEMET part has a maximum thickness of 0.055" compared to 0.051" for the Knowles Syfer part. This 0.004" difference is within standard PCB assembly clearances for 0805 components.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (unlimited moisture sensitivity). Both carry AEC-Q200 automotive qualification.

Q: What is the basis for substitution between these parts?

A: Substitution is based on matching electrical parameters (capacitance, tolerance, voltage, temperature coefficient, operating range), mechanical compatibility (0805 package, surface-mount MLCC), and automotive certifications (AEC-Q200). All specified parameters are equivalent between the two parts.
