Substitute Part Grouping Explanation
Substitution eligibility for the GCM033R71A682KA03D is determined by the following critical parameters:
Mandatory Matching Parameters:
- Capacitance value: 6800 pF
- Tolerance: ±10%
- Temperature coefficient: X7R
- Package format: 0201 (0603 Metric)
- Mounting type: Surface Mount, MLCC
- Operating temperature range: -55°C to 125°C
- Automotive qualification: AEC-Q200
Allowable Variation:
- Voltage rating: Equal to or greater than 10V (uprating is acceptable; downrating is not)
The substitute part CGA1A2X7R1C682K030BA from TDK Corporation meets all mandatory matching parameters and provides an increased voltage rating of 16V, which is compatible with applications designed for the 10V rated part.

Engineering Selection Recommendations
The CGA1A2X7R1C682K030BA from TDK Corporation is a direct functional substitute for the GCM033R71A682KA03D. Both parts maintain identical electrical characteristics for capacitance, tolerance, and temperature coefficient, with matching physical package dimensions and mounting specifications.
The substitute part carries a higher voltage rating (16V versus 10V), which presents no compatibility issues in applications designed for the original 10V part. Both components are AEC-Q200 qualified for automotive applications and maintain ROHS3 compliance with MSL 1 moisture sensitivity rating.
Selection between these parts should be based on availability, supply chain requirements, and cost considerations, as both are functionally equivalent for the specified application parameters.
Frequently Asked Questions (FAQ)
Q: Can the CGA1A2X7R1C682K030BA be used as a direct replacement for the GCM033R71A682KA03D?
A: Yes. Both parts share identical capacitance (6800 pF), tolerance (±10%), temperature coefficient (X7R), package format (0201), and operating temperature range (-55°C to 125°C). The substitute part's higher voltage rating (16V) is compatible with applications designed for 10V operation.
Q: What is the significance of the higher voltage rating on the substitute part?
A: The 16V rating on the CGA1A2X7R1C682K030BA indicates a higher maximum operating voltage specification. This does not affect performance in circuits designed for 10V operation and may provide additional design margin in certain applications.
Q: Are both parts suitable for automotive applications?
A: Yes. Both the GCM033R71A682KA03D and CGA1A2X7R1C682K030BA carry AEC-Q200 automotive qualification and are suitable for automotive-grade applications.
Q: Do these parts have identical physical dimensions?
A: Yes. Both parts are packaged in 0201 (0603 Metric) format with identical dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum thickness of 0.013" (0.33mm). They are mechanically interchangeable on PCB layouts.
Q: What is the moisture sensitivity level for both parts?
A: Both parts are rated MSL 1 (Unlimited), indicating minimal moisture sensitivity and no special storage or handling requirements beyond standard component handling practices.
Q: Are both parts RoHS compliant?
A: Yes. Both the GCM033R71A682KA03D and CGA1A2X7R1C682K030BA are ROHS3 compliant.
