Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C0402C331M8JAC7867 is determined by the following critical parameters:

Fixed Parameters (Must Match):

• Capacitance: 330 pF
• Package / Case: 0402 (1005 Metric)
• Mounting Type: Surface Mount, MLCC
• Temperature Coefficient: U2J
• Operating Temperature Range: -55°C ~ 125°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameters (Allowed to Differ):

• Tolerance: ±20% (main part) to ±5% (substitute)
• Voltage - Rated: 10V (main part) to 50V (substitute)

The substitute part C0402C331J5JAC7867 maintains identical capacitance, package dimensions, temperature characteristics, and compliance certifications. The substitute offers improved tolerance specification (±5% versus ±20%) and higher voltage rating (50V versus 10V), providing enhanced performance margin and tighter capacitance accuracy within the same physical footprint.

Parameter Comparison

Engineering Selection Recommendations

C0402C331M8JAC7867 Selection Criteria:

• Applications with strict 10V voltage ceiling requirements
• Designs where ±20% tolerance specification is acceptable
• Cost-optimized designs where tighter tolerance is not required

C0402C331J5JAC7867 Selection Criteria:

• Applications requiring improved capacitance accuracy (±5% tolerance)
• Designs operating below 50V where voltage margin enhancement is beneficial
• Systems requiring higher reliability through tighter component specifications
• Inventory availability: 11,086 pcs in stock versus 717 pcs for main part

Both parts maintain identical physical dimensions, thermal characteristics, and regulatory compliance (ROHS3, REACH Unaffected, EAR99 classification). Selection between these parts depends on circuit voltage requirements and tolerance specifications rather than package or thermal considerations.

Frequently Asked Questions (FAQ)

Q: Can C0402C331J5JAC7867 replace C0402C331M8JAC7867 in all applications?

A: The substitute part is compatible in applications where the circuit voltage does not exceed 50V and where ±5% tolerance meets or exceeds the design requirement. The higher voltage rating and tighter tolerance of the substitute provide enhanced performance margin. Verify circuit voltage requirements before substitution.

Q: What is the physical difference between these two parts?

A: Both parts are identical in physical dimensions: 0402 (1005 Metric) package measuring 0.039" L x 0.020" W (1.00mm x 0.50mm) with maximum thickness of 0.022" (0.55mm). They are mechanically interchangeable on PCB layouts.

Q: Are there differences in temperature performance?

A: Both parts share identical temperature coefficient (U2J) and operating temperature range (-55°C ~ 125°C). Temperature performance characteristics are equivalent.

Q: What does the tolerance difference mean for circuit design?

A: The main part specifies ±20% tolerance, meaning capacitance can range from 264 pF to 396 pF. The substitute specifies ±5% tolerance, with capacitance ranging from 313.5 pF to 346.5 pF. Tighter tolerance reduces capacitance variation in production and improves circuit predictability.

Q: Are both parts RoHS compliant?

A: Yes, both C0402C331M8JAC7867 and C0402C331J5JAC7867 are ROHS3 compliant with REACH Unaffected status and EAR99 ECCN classification.

Q: What is the moisture sensitivity level for these parts?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions and unlimited shelf life under standard storage conditions.
