Substitute Part Grouping Explanation

Substitution eligibility for the CSR1206JTR240 is determined by the following critical parameters:

• Resistance Value: Must be 240 mOhms
• Package Type: Must be 1206 (3216 Metric)
• Power Rating: Must be 0.5W minimum
• Composition: Thick film construction
• Temperature Range: Must support -55°C to 155°C operation
• Compliance: ROHS3 compliance required

The RCWE1206R240FKEA qualifies as a substitute because it maintains identical resistance, package, power rating, temperature range, and compliance specifications. The improved tolerance (±1% versus ±5%) and automotive AEC-Q200 qualification represent enhancements rather than deviations from the core electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

The RCWE1206R240FKEA is a direct substitute for the CSR1206JTR240 in applications requiring 240 mOhms current sense resistors in 1206 package format. Both parts maintain identical electrical specifications for resistance, power rating, and temperature performance. The substitute offers improved tolerance accuracy (±1% versus ±5%) and automotive AEC-Q200 qualification, making it suitable for automotive and high-reliability applications. Both parts are ROHS3 compliant with unlimited moisture sensitivity rating. Selection between these parts should be based on application requirements for tolerance precision and automotive qualification status, with the substitute providing enhanced specifications where needed.

Frequently Asked Questions (FAQ)

Q: Can RCWE1206R240FKEA replace CSR1206JTR240 in existing designs?

A: Yes. Both parts share identical resistance value (240 mOhms), package type (1206), power rating (0.5W), temperature range (-55°C to 155°C), and compliance status (ROHS3). The substitute's improved tolerance (±1%) is compatible with designs specified for ±5% tolerance.

Q: What are the physical dimension differences between these parts?

A: CSR1206JTR240 dimensions are 0.120" L × 0.061" W (3.05mm × 1.55mm) with 0.026" maximum seated height. RCWE1206R240FKEA dimensions are 0.122" L × 0.063" W (3.10mm × 1.60mm) with 0.028" maximum seated height. Both fit standard 1206 package footprints with negligible dimensional variance.

Q: Does the substitute require different handling or storage procedures?

A: No. Both parts have identical Moisture Sensitivity Level 1 (Unlimited) rating, indicating no special moisture control requirements during storage or handling.

Q: What is the significance of AEC-Q200 qualification on the substitute?

A: AEC-Q200 qualification indicates the RCWE1206R240FKEA meets automotive industry reliability standards. This certification is beneficial for automotive applications but does not affect compatibility in non-automotive current sense applications.

Q: Are there inventory or lead time considerations for substitution?

A: The substitute (RCWE1206R240FKEA) has significantly higher inventory availability (64394 units versus 1137 units), which may provide supply chain advantages in high-volume procurement scenarios.
