Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSR1206FTR910 is determined by strict alignment of the following parameters:

• Resistance value: 910 mOhms
• Tolerance: ±1%
• Power rating: 0.5W minimum
• Package type: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C minimum
• Termination count: 2
• RoHS compliance: ROHS3 Compliant

The RCWE1206R910FKEA from Vishay Dale meets all electrical and mechanical requirements for direct substitution. Both parts share identical resistance, tolerance, power rating, package dimensions, and thermal specifications. The substitute part includes additional automotive qualification (AEC-Q200) and moisture-resistant features, which represent enhancements rather than deviations from the original specification.

Parameter Comparison

Engineering Selection Recommendations

Both the CSR1206FTR910 and RCWE1206R910FKEA are Active status components with full ROHS3 compliance and REACH unaffected status. The electrical and thermal performance characteristics are identical across both parts. The RCWE1206R910FKEA includes AEC-Q200 automotive qualification and moisture-resistant features, making it suitable for applications requiring enhanced reliability in automotive or high-humidity environments. Dimensional variations between the two parts are within standard manufacturing tolerances for the 1206 package class and do not affect PCB layout compatibility. Selection between these parts should be based on application requirements for automotive qualification and environmental resilience.

Frequently Asked Questions (FAQ)

Q: Can RCWE1206R910FKEA replace CSR1206FTR910 in existing designs?

A: Yes. Both parts share identical electrical specifications (910 mOhms ±1%, 0.5W, ±100ppm/°C) and operate across the same temperature range (-55°C to 155°C). The 1206 package footprint is compatible. Dimensional tolerances are within standard PCB design margins.

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

A: AEC-Q200 is an automotive industry standard for passive component reliability. The RCWE1206R910FKEA meets this qualification, indicating suitability for automotive applications. This is an enhancement feature not present on the original CSR1206FTR910.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within standard 1206 package tolerances. CSR1206FTR910 measures 3.05mm x 1.55mm with 0.65mm max height; RCWE1206R910FKEA measures 3.10mm x 1.60mm with 0.70mm max height. These differences do not affect standard PCB layout compatibility.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity concerns during storage or handling.

Q: Are both parts RoHS compliant?

A: Yes. Both CSR1206FTR910 and RCWE1206R910FKEA are ROHS3 compliant and REACH unaffected.
