Key Parameters

Substitute Part Grouping Explanation

Substitution of the VJ0805A331KXCMP is determined by the following critical parameters:

Fixed Parameters (Must Match):

• Capacitance: 330 pF
• Package / Case: 0805 (2012 Metric)
• Temperature Coefficient: C0G, NP0
• Mounting Type: Surface Mount, MLCC
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Thickness (Max): 0.057" (1.45mm)

Variable Parameters (Allowed to Differ):

• Voltage - Rated: May be equal or higher than 200V
• Tolerance: May be tighter (lower percentage) than ±10%

The substitute part VJ0805A331JXEAT maintains identical capacitance, package, temperature coefficient, and physical dimensions while providing upgraded voltage rating (500V) and improved tolerance (±5%).

Parameter Comparison

Engineering Selection Recommendations

The VJ0805A331JXEAT serves as a direct substitute for the VJ0805A331KXCMP in applications where the circuit design permits higher voltage rating. Both components maintain Active product status and ROHS3 compliance. The substitute part provides enhanced voltage margin (500V versus 200V) and tighter capacitance tolerance (±5% versus ±10%), making it suitable for designs requiring improved performance specifications within the same 0805 package footprint. Selection between these parts depends on circuit voltage requirements and tolerance specifications of the application.

Frequently Asked Questions (FAQ)

Q: Can VJ0805A331JXEAT replace VJ0805A331KXCMP in any application?

A: The VJ0805A331JXEAT is electrically compatible as a substitute when the circuit voltage rating does not exceed 500V. The higher voltage rating of the substitute part does not create incompatibility in lower voltage applications. Physical package dimensions are identical, ensuring PCB layout compatibility.

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

A: The VJ0805A331KXCMP has ±10% capacitance tolerance, while VJ0805A331JXEAT has ±5% tolerance. The tighter tolerance of the substitute part provides more precise capacitance values, which may be beneficial in applications with strict capacitance requirements.

Q: Are both parts suitable for the same temperature range?

A: Yes. Both VJ0805A331KXCMP and VJ0805A331JXEAT operate across the identical temperature range of -55°C to 150°C with C0G/NP0 temperature coefficient, ensuring stable capacitance performance across environmental conditions.

Q: Do these parts have the same moisture sensitivity level?

A: Yes. Both components are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.

Q: Can the substitute part be used in high-voltage applications?

A: The VJ0805A331JXEAT is rated for 500V, making it suitable for applications operating up to this voltage level. The original VJ0805A331KXCMP is limited to 200V applications.
