Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSR1206FTR330 is determined by strict equivalence across the following parameters: resistance value (330 mOhms), tolerance (±1%), power rating (0.5W), package type (1206), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, REACH Unaffected). Two substitute parts meet these criteria:

Direct Equivalent (CSR1206FKR330): Identical specifications from the same manufacturer series with different packaging designation (FK vs FT termination).

Upgrade Equivalent (RCWE1206R330FKEA): Meets all core electrical and mechanical parameters with additional automotive qualification (AEC-Q200) and moisture-resistant features, representing an enhanced alternative suitable for automotive and high-reliability applications.

Parameter Comparison

Engineering Selection Recommendations

CSR1206FKR330 is the direct equivalent substitute, maintaining identical electrical and mechanical specifications with higher inventory availability (19100 units). Selection is appropriate for applications requiring standard current sense resistor functionality without automotive qualification requirements.

RCWE1206R330FKEA is the upgrade substitute, certified to AEC-Q200 automotive standards with integrated moisture-resistant features. Selection is appropriate for automotive applications, high-reliability systems, or environments requiring enhanced environmental protection. All three parts maintain ROHS3 compliance and unlimited moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can CSR1206FKR330 be used as a direct replacement for CSR1206FTR330?

A: Yes. Both parts share identical electrical specifications (330 mOhms ±1%, 0.5W), composition (thick film), temperature characteristics (±100ppm/°C, -55°C to 155°C), and 1206 package dimensions. The difference is in termination type designation (FK vs FT), which does not affect functional compatibility.

Q: What is the primary difference between CSR1206FTR330 and RCWE1206R330FKEA?

A: Both parts meet identical core electrical and mechanical requirements. RCWE1206R330FKEA adds AEC-Q200 automotive qualification and moisture-resistant features, making it suitable for automotive and high-reliability applications. Dimensional tolerances are slightly tighter (3.10mm x 1.60mm vs 3.05mm x 1.55mm length and width).

Q: Are all three parts interchangeable in the same PCB footprint?

A: Yes. All three parts use the 1206 (3216 Metric) package with compatible termination spacing and mounting requirements. Slight dimensional variations (maximum 0.05mm difference in length and width) are within standard PCB design tolerances.

Q: Which substitute should be selected for cost optimization?

A: CSR1206FKR330 offers the lowest cost consideration with highest inventory availability (19100 units) while maintaining full electrical and mechanical equivalence to the original part.

Q: Is RCWE1206R330FKEA suitable for non-automotive applications?

A: Yes. RCWE1206R330FKEA meets all specifications required for standard applications and adds automotive certification as an additional qualification. It is functionally compatible with any application requiring the base specifications.
