Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 08055C331K4T2A is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 330 pF
• Tolerance: ±10%
• Temperature Coefficient: X7R
• Package / Case: 0805 (2012 Metric)
• Mounting Type: Surface Mount, MLCC
• Operating Temperature Range: -55°C ~ 125°C
• Ratings: AEC-Q200 (automotive qualification)
• RoHS Status: ROHS3 Compliant

Allowable Variation:

• Voltage - Rated: Equal to or greater than 50V (higher voltage ratings provide design margin and are electrically compatible in applications rated for 50V)

The substitute part 08051C331K4T2A meets all mandatory parameters and provides an upgraded voltage rating of 100V, making it suitable for direct replacement in applications where the original 50V specification is required.

Parameter Comparison

Engineering Selection Recommendations

The 08051C331K4T2A serves as a direct substitute for the 08055C331K4T2A based on the following engineering criteria:

Electrical Compatibility: Both parts maintain identical capacitance (330 pF), tolerance (±10%), and temperature coefficient (X7R). The substitute part's 100V rating exceeds the original 50V specification, providing additional design margin without compromising circuit performance in applications rated for 50V operation.

Mechanical Compatibility: Both parts share identical package dimensions (0805 / 2012 Metric), thickness, and surface mount configuration, ensuring direct PCB footprint compatibility without layout modifications.

Compliance & Qualification: Both parts carry AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating, meeting identical reliability and environmental standards required for automotive applications.

Product Status: Both parts maintain active production status with established supply chains.

Frequently Asked Questions (FAQ)

Q: Can the 08051C331K4T2A (100V) be used in place of the 08055C331K4T2A (50V)?

A: Yes. The substitute part's higher voltage rating (100V) is electrically compatible with circuits designed for 50V operation. Higher voltage-rated capacitors function correctly in lower voltage applications and provide additional design margin.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 0805 (2012 Metric) package with identical length (0.079"), width (0.049"), and maximum thickness (0.037"). They share the same PCB footprint and mounting requirements.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both the 08055C331K4T2A and 08051C331K4T2A carry AEC-Q200 qualification, confirming suitability for automotive applications.

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

A: There is no difference. Both parts maintain ±10% tolerance, ensuring identical capacitance accuracy across the specified operating temperature range.

Q: Are there any environmental or compliance differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level) rating. They meet identical environmental and regulatory requirements.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. Identical package dimensions, mounting type, and electrical specifications allow direct substitution without PCB redesign or assembly process modifications.
