Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C0805C331M2RAC7800 is determined by the following critical parameters:

Fixed Parameters (Must Match):

• Capacitance: 330 pF
• Voltage Rating: 200V
• Package: 0805 (2012 Metric)
• Mounting Type: Surface Mount, MLCC
• Physical Dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Thickness: 0.035" (0.88mm) maximum
• Operating Temperature Range: -55°C ~ 125°C

Variable Parameters (Allowed to Differ):

• Tolerance: ±20%, ±10%, or ±5%
• Temperature Coefficient: X7R or C0G/NP0
• Series Classification: SMD Comm X7R or SMD Comm C0G

All substitute parts maintain identical electrical ratings, mechanical compatibility, and regulatory compliance (RoHS3, REACH Unaffected, EAR99, MSL 1). Substitution is valid across tolerance grades and temperature coefficient types within the same package footprint and electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status with full regulatory compliance. Selection between substitute options is determined by application-specific tolerance and temperature coefficient requirements:

For X7R Temperature Coefficient Applications:

• C0805C331J2RAC7800 (±5% tolerance) provides tighter capacitance control with X7R stability
• C0805C331K2RAC7800 (±10% tolerance) offers standard X7R performance with moderate tolerance

For C0G/NP0 Temperature Coefficient Applications:

• C0805C331J2GAC7800 (±5% tolerance) delivers maximum capacitance precision with C0G stability and low ESL characteristics
• C0805C331K2GAC7800 (±10% tolerance) provides C0G performance with standard tolerance

All parts are RoHS3 compliant, REACH unaffected, and carry MSL 1 rating. Mechanical compatibility is identical across all options, ensuring direct PCB footprint substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can C0805C331J2RAC7800 directly replace C0805C331M2RAC7800?

A: Yes. Both parts share identical capacitance (330 pF), voltage rating (200V), temperature coefficient (X7R), package (0805), and physical dimensions. The substitute has tighter tolerance (±5% versus ±20%), which is compatible with the original application. No PCB modification is required.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients?

A: X7R provides ±15% capacitance variation across the -55°C to 125°C operating range. C0G/NP0 provides ±30 ppm/°C stability, resulting in minimal capacitance drift. Selection depends on application sensitivity to temperature-induced capacitance changes.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging, matching the original C0805C331M2RAC7800 format. Physical dimensions and mounting characteristics are identical.

Q: Does tolerance grade affect PCB assembly compatibility?

A: No. Tolerance differences (±20%, ±10%, ±5%) do not affect mechanical fit, soldering process, or PCB footprint. Selection is based on circuit performance requirements, not assembly compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance, REACH unaffected status, and MSL 1 rating, matching the regulatory profile of the original C0805C331M2RAC7800.
