Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VJ1206A331KXAMC are qualified based on the following criteria:

Mandatory Matching Parameters:

• Capacitance value: 330 pF
• Package / Case: 1206 (3216 Metric)
• Temperature Coefficient: C0G, NP0
• Mounting Type: Surface Mount, MLCC
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Voltage - Rated: Equal to or greater than 50V
• Tolerance: ±10% or tighter (±5%)
• Operating Temperature Range: Must encompass or match the specified range
• Manufacturer: Different manufacturers permitted if all parameters align

Parts are grouped into two categories: Upgrade substitutes (higher voltage rating with improved tolerance) and Direct substitutes (equivalent electrical and mechanical specifications from alternative manufacturers).

Parameter Comparison

Engineering Selection Recommendations

VJ1206A331JXCAT (Upgrade Substitute): This part maintains the same manufacturer (Vishay Vitramon) and base product series (VJ1206). The upgrade provides 200V rated voltage compared to the 50V specification of the main part, with improved tolerance of ±5% versus ±10%. Both parts share identical operating temperature range (-55°C ~ 150°C), package dimensions, and compliance certifications. This substitute is suitable for applications requiring higher voltage margin or tighter capacitance tolerance while maintaining the same physical footprint and thermal characteristics.

C1206C331K5GAC7800 (Direct Substitute): This KEMET part matches the electrical specifications of the main part exactly: 330 pF capacitance, ±10% tolerance, and 50V rated voltage. The 1206 package, C0G/NP0 temperature coefficient, and ROHS3 compliance are identical. The operating temperature range of -55°C ~ 125°C is within acceptable limits for most applications, though it does not extend to the full 150°C upper limit of the Vishay part. The reduced thickness (0.035" versus 0.067") may provide advantages in space-constrained designs. This substitute is appropriate for direct replacement in equivalent voltage and tolerance applications.

Frequently Asked Questions (FAQ)

Q: Can VJ1206A331JXCAT be used as a direct replacement for VJ1206A331KXAMC?

A: Yes. VJ1206A331JXCAT is a qualified upgrade substitute. It maintains identical capacitance (330 pF), package (1206), temperature coefficient (C0G/NP0), and operating temperature range (-55°C ~ 150°C). The higher voltage rating (200V versus 50V) and tighter tolerance (±5% versus ±10%) provide improved performance margins without affecting mechanical or thermal compatibility.

Q: What are the differences between the Vishay and KEMET substitutes?

A: Both maintain the core electrical specification of 330 pF, ±10% tolerance at 50V with C0G/NP0 characteristics in a 1206 package. The primary differences are: manufacturer (Vishay Vitramon versus KEMET), operating temperature upper limit (150°C versus 125°C), and physical thickness (1.70mm versus 0.88mm). The KEMET part's reduced thickness may be advantageous in compact PCB designs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts—VJ1206A331JXCAT and C1206C331K5GAC7800—are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the compliance profile of the main part VJ1206A331KXAMC.

Q: Can C1206C331K5GAC7800 be used in applications requiring operation up to 150°C?

A: No. The KEMET part C1206C331K5GAC7800 specifies an operating temperature range of -55°C ~ 125°C, which does not extend to the 150°C upper limit. For applications requiring full -55°C ~ 150°C operation, use VJ1206A331KXAMC or VJ1206A331JXCAT.

Q: Does the reduced thickness of C1206C331K5GAC7800 affect electrical performance?

A: No. Thickness variation does not alter the electrical characteristics (capacitance, tolerance, voltage rating, or temperature coefficient). The reduced thickness (0.035" versus 0.067") is a physical design difference that may provide PCB layout advantages in space-constrained applications without affecting electrical function.

Q: What is the significance of the ±5% tolerance in VJ1206A331JXCAT compared to ±10% in the main part?

A: Tighter tolerance (±5%) means the actual capacitance value will be closer to the nominal 330 pF specification. This is beneficial for precision applications where capacitance accuracy is critical. The ±5% tolerance is a performance improvement over the ±10% specification of VJ1206A331KXAMC.
