Frequently Asked Questions (FAQ)

Q: Can CRCW25122K80FKEG be used as a direct replacement for ERJ-S1TF2801U?

A: Yes. Both parts share identical resistance (2.8 kOhms), tolerance (±1%), power rating (1W), package (2512), composition (thick film), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and automotive qualification (AEC-Q200). Physical dimensions are within acceptable tolerance for PCB assembly.

Q: Are there differences in the physical dimensions between these parts?

A: Minor dimensional variations exist. The ERJ-S1TF2801U measures 0.252" L x 0.126" W (6.40mm x 3.20mm), while the CRCW25122K80FKEG measures 0.248" L x 0.124" W (6.30mm x 3.15mm). Both have identical height (0.028" / 0.70mm maximum). These variations are within standard PCB pad tolerances for 2512 package footprints.

Q: Do both parts meet automotive standards?

A: Yes. Both the ERJ-S1TF2801U and CRCW25122K80FKEG carry AEC-Q200 qualification, confirming compliance with automotive reliability and performance standards.

Q: What is the difference between the anti-sulfur feature on the ERJ-S1TF2801U?

A: The ERJ-S1TF2801U includes anti-sulfur coating as a specified feature. The CRCW25122K80FKEG specification does not explicitly list this feature in the provided data. This distinction should be evaluated based on application requirements in corrosive or high-sulfur environments.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, confirming compliance with environmental and handling standards.
