Frequently Asked Questions (FAQ)

Q: Can CRCW06036M49FKEA replace RC1608F6494CS in any circuit application?

A: Yes, from an electrical and mechanical standpoint. Both parts share identical resistance value (6.49 MOhms), tolerance (±1%), power rating (0.1W), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and 0603 package format. The CRCW06036M49FKEA carries additional Automotive AEC-Q200 qualification, which does not restrict its use in non-automotive applications.

Q: What is the difference between the moisture-resistant feature of RC1608F6494CS and the AEC-Q200 rating of CRCW06036M49FKEA?

A: These are different feature classifications. The RC1608F6494CS specifies moisture-resistant construction as a material property. The CRCW06036M49FKEA carries Automotive AEC-Q200 qualification, which is an automotive industry reliability standard. Both parts maintain Moisture Sensitivity Level 1 (Unlimited), indicating equivalent moisture handling capability.

Q: Are there packaging differences between these two parts?

A: The CRCW06036M49FKEA is specified as Tape & Reel (TR) packaging. The RC1608F6494CS packaging format is not specified in the provided data. Tape & Reel format is standard for automated assembly processes. Verify packaging requirements for your manufacturing process before selection.

Q: Do both parts comply with environmental regulations?

A: Yes. Both RC1608F6494CS and CRCW06036M49FKEA are ROHS3 Compliant and REACH Unaffected, meeting current environmental compliance requirements.

Q: What is the significance of the ±100ppm/°C temperature coefficient?

A: The temperature coefficient indicates resistance value change per degree Celsius across the operating temperature range. Both parts share identical ±100ppm/°C specification, ensuring equivalent temperature stability performance across the -55°C ~ 155°C operating range.
