Key Parameters

Substitute Part Grouping Explanation

Substitution for the C0805C519D5GAC7800 is determined by the following critical parameters:

Primary Substitution Criteria:

• Capacitance value: 5.1 pF (exact match required)
• Voltage rating: 50V minimum
• Temperature coefficient: C0G/NP0 (required for stability)
• Package: 0805 (2012 Metric) surface-mount form factor
• Mounting type: Surface Mount MLCC
• Operating temperature range: -55°C to 125°C minimum
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

Tolerance Consideration: The main part specifies ±0.5pF tolerance. Substitute parts with tighter tolerance specifications (such as ±0.25pF) are functionally equivalent and represent an upgrade path, as they maintain or exceed the electrical performance envelope of the original specification.

Engineering Selection Recommendations

C0805C519C5GAC7800 as Direct Substitute:

The C0805C519C5GAC7800 is a direct substitute for the C0805C519D5GAC7800. Both parts are manufactured by KEMET and maintain identical electrical specifications for capacitance (5.1 pF), voltage rating (50V), temperature coefficient (C0G/NP0), and operating temperature range (-55°C to 125°C). Both components are housed in the 0805 (2012 Metric) surface-mount package with identical physical dimensions and thickness.

The substitute part features a tighter tolerance specification (±0.25pF versus ±0.5pF), which represents an upgrade in precision without any degradation of performance. Both parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and maintain active product status.

Selection between these parts is based on tolerance requirements and inventory availability. The C0805C519C5GAC7800 is suitable for applications requiring higher capacitance accuracy. Both parts are electrically and mechanically interchangeable in 0805 surface-mount applications.

Frequently Asked Questions (FAQ)

Q: Can C0805C519C5GAC7800 replace C0805C519D5GAC7800 in existing designs?

A: Yes. Both parts share identical capacitance (5.1 pF), voltage rating (50V), temperature coefficient (C0G/NP0), package (0805), and operating temperature range (-55°C to 125°C). The substitute has tighter tolerance (±0.25pF), which is compatible with designs specified for ±0.5pF tolerance.

Q: What is the significance of the tolerance difference between these parts?

A: The main part specifies ±0.5pF tolerance, while the substitute specifies ±0.25pF tolerance. Tighter tolerance indicates higher manufacturing precision. Applications requiring the original ±0.5pF specification can use the substitute without modification, as the substitute tolerance is contained within the original specification window.

Q: Are both parts suitable for the same PCB assembly process?

A: Yes. Both parts use identical 0805 (2012 Metric) surface-mount packaging with matching physical dimensions (2.00 × 1.25 mm) and maximum thickness (0.88 mm). No changes to PCB layout, footprint, or reflow profile are required.

Q: What compliance certifications apply to both parts?

A: Both C0805C519D5GAC7800 and C0805C519C5GAC7800 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Both parts are classified under ECCN EAR99 and HTSUS 8532.24.0020.

Q: Is there a difference in operating temperature performance between these parts?

A: No. Both parts operate across the identical temperature range of -55°C to 125°C with C0G/NP0 temperature coefficient, ensuring stable capacitance performance across the full operating envelope.
