Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GCM188R91H682KA37D is determined by strict equivalence across the following critical parameters:

Capacitance value must match exactly at 6800 pF. Tolerance must remain ±10%. Voltage rating must be 50V or higher. Temperature coefficient classification must be X8R. Operating temperature range must span -55°C to 150°C minimum. Package designation must be 0603 (1608 Metric) with identical physical dimensions. Mounting type must be Surface Mount MLCC. Moisture Sensitivity Level must be 1 (Unlimited). RoHS3 compliance and AEC-Q200 automotive rating are mandatory for equivalent substitution.

The substitute part CGA3E2X8R1H682K080AA manufactured by TDK Corporation meets all these criteria and qualifies as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The GCM188R91H682KA37D remains the primary selection for new automotive designs due to its active production status. Both parts satisfy identical electrical and mechanical specifications, with full compliance to AEC-Q200 automotive qualification and ROHS3 environmental standards.

The CGA3E2X8R1H682K080AA substitute is suitable for legacy system maintenance, field replacements, or supply chain contingency scenarios. The "Not For New Designs" status of the TDK part does not affect functional equivalence but indicates manufacturer recommendation against incorporation into new product development.

Selection between these parts should be based on availability, procurement lead time, and design phase requirements rather than electrical performance differences, as none exist within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can CGA3E2X8R1H682K080AA be used as a direct replacement for GCM188R91H682KA37D in automotive applications?

A: Yes. Both parts are parametrically equivalent across all critical electrical and mechanical specifications. Both carry AEC-Q200 automotive qualification and ROHS3 compliance. Direct substitution is electrically and mechanically valid.

Q: What is the significance of the "Not For New Designs" status on the TDK part?

A: This designation indicates TDK's recommendation against using this part number in new product development. It does not affect functional compatibility or performance. The part remains suitable for replacement, repair, and legacy system applications.

Q: Are there any physical compatibility concerns when substituting between these parts?

A: No. Both parts share identical package designation (0603 / 1608 Metric), physical dimensions (0.063" L x 0.031" W), and maximum thickness (0.035"). PCB footprints and assembly processes are interchangeable.

Q: Do both parts require identical handling and storage conditions?

A: Yes. Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling. Standard component storage practices apply to both.

Q: What parameters must remain constant for substitution eligibility?

A: Capacitance (6800 pF), tolerance (±10%), voltage rating (50V), temperature coefficient (X8R), operating temperature range (-55°C to 150°C), package type (0603), and compliance certifications (AEC-Q200, ROHS3) must all match exactly.
