Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSR1206FKR620 is determined by strict equivalence across the following parameters:

• Resistance value: 620 mOhms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Package type: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)

The RCWE1206R620FKEA from Vishay Dale meets all these criteria and qualifies as a direct substitute. Both parts share identical electrical performance specifications and mechanical compatibility within the 1206 package footprint.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can RCWE1206R620FKEA replace CSR1206FKR620 in existing designs?

A: Yes. Both parts share identical resistance (620 mOhms), tolerance (±1%), power rating (0.5W), package (1206), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). Mechanical footprint compatibility is confirmed within the 1206 package specification.

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

A: AEC-Q200 is an automotive industry standard qualification. The RCWE1206R620FKEA meets this standard, indicating suitability for automotive applications. This qualification is not required for non-automotive applications but does not restrict use in general industrial designs.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within manufacturing tolerances. CSR1206FKR620 dimensions are 0.120" L × 0.061" W (3.05mm × 1.55mm) with 0.026" max height. RCWE1206R620FKEA dimensions are 0.122" L × 0.063" W (3.10mm × 1.60mm) with 0.028" max height. Both conform to 1206 package specifications and are PCB footprint compatible.

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

A: Yes. Both parts carry MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture precautions are required during storage or handling.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8533.21.0030.
