Parameter Comparison

Engineering Selection Recommendations

Both the RC6432F1212CS and CRCW251212K1FKEG maintain Active product status, ensuring continued availability and manufacturing support. Both components satisfy ROHS3 compliance and REACH requirements, meeting current regulatory standards for electronic component procurement.

The CRCW251212K1FKEG carries AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components. Dimensional variations between the two parts are minimal, with width and height differences within typical manufacturing tolerances for the 2512 package class.

Selection between these parts should be based on supply chain availability, packaging format requirements (the Vishay part is supplied in Tape & Reel format), and application-specific qualification requirements.

Frequently Asked Questions (FAQ)

Q: Can the CRCW251212K1FKEG directly replace the RC6432F1212CS in existing circuit designs?

A: Yes. Both components share identical electrical specifications (12.1 kOhms ±1%, 1W, ±100ppm/°C), operate across the same temperature range (-55°C to 155°C), and use the 2512 (6432 Metric) package. Dimensional differences are within standard manufacturing tolerances for this package class.

Q: What is the significance of the AEC-Q200 rating on the Vishay part?

A: AEC-Q200 is an automotive qualification standard. The CRCW251212K1FKEG meets this specification, making it suitable for automotive applications. The Samsung part does not carry this designation but remains suitable for general industrial and consumer applications.

Q: Are there packaging differences between these parts?

A: The RC6432F1212CS is supplied in standard packaging, while the CRCW251212K1FKEG is supplied in Tape & Reel (TR) format. This affects handling and assembly processes but does not impact electrical or mechanical compatibility.

Q: Do both parts meet current environmental compliance standards?

A: Yes. Both components are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component procurement and use.

Q: What are the critical parameters for confirming substitution compatibility?

A: Resistance value (12.1 kOhms), tolerance (±1%), power rating (1W), package type (2512), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C) must match exactly. Both parts satisfy these criteria.
