Key Parameters

Substitute Part Grouping Explanation

Substitution of the D101J39COGLABAA is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance value: 100 pF (exact match required)
• Tolerance: ±5% (acceptable range for general-purpose applications)
• Voltage rating: 500V minimum (equal or higher acceptable)
• Temperature coefficient: C0G/NP0 (required for temperature stability)
• Operating temperature range: -55°C to 125°C (minimum requirement)
• Mounting type: Through Hole (required for PCB compatibility)
• Package configuration: Radial ceramic disc (mechanical fit requirement)

The substitute part C322C101JCG5TA meets all these criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The C322C101JCG5TA is a direct functional equivalent to the D101J39COGLABAA based on matching electrical specifications and through-hole radial package configuration. The substitute part is currently in active production status, ensuring long-term availability compared to the obsolete original part.

The C322C101JCG5TA offers improved compliance status with ROHS3 certification, whereas the original part is RoHS non-compliant. Both parts maintain identical electrical performance across the specified operating temperature range and voltage rating.

Physical dimensions differ between the two parts: the original D101J39COGLABAA measures 0.394" diameter with 0.375" lead spacing, while the C322C101JCG5TA is smaller at 0.200" L x 0.125" W with 0.200" lead spacing. Lead style differs (straight versus formed leads), which may require PCB layout verification for mechanical fit and soldering compatibility.

Frequently Asked Questions (FAQ)

Q: Can C322C101JCG5TA be used as a direct replacement for D101J39COGLABAA?

A: Yes, the C322C101JCG5TA is electrically equivalent. Both parts share identical capacitance (100 pF), tolerance (±5%), voltage rating (500V), temperature coefficient (C0G/NP0), and operating temperature range (-55°C to 125°C). Physical dimensions and lead styles differ, requiring PCB layout assessment for mechanical compatibility.

Q: What are the key differences between these two parts?

A: The primary differences are physical dimensions, lead style (straight versus formed), and product status. The D101J39COGLABAA is obsolete with RoHS non-compliance, while the C322C101JCG5TA is active production with ROHS3 compliance. Electrical performance is identical.

Q: Are there any compliance considerations when substituting?

A: The C322C101JCG5TA provides improved compliance with ROHS3 certification. If RoHS compliance is a system requirement, the substitute part offers an advantage over the original obsolete part.

Q: Will the smaller package size of C322C101JCG5TA affect circuit performance?

A: Package size does not affect electrical performance for this application. Both parts deliver identical capacitance, voltage rating, and temperature stability. Physical size differences are relevant only for PCB layout and mechanical fit considerations.

Q: What should be verified before implementing the substitute part?

A: Verify PCB footprint compatibility with the smaller dimensions and formed lead style of the C322C101JCG5TA. Confirm that lead spacing (0.200" versus 0.375") accommodates existing through-hole positions. Electrical performance requires no additional verification.
