Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F3R01CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (3.01 Ohms), tolerance (±1%), and power rating (0.063W / 1/16W) must be identical.

Mechanical Compatibility: Package type (0402 / 1005 Metric), physical dimensions (0.039" L x 0.020" W), and maximum seated height (0.016") must match exactly to ensure PCB assembly compatibility.

Environmental & Compliance Requirements: Operating temperature range (-55°C to 155°C), RoHS3 compliance, and Moisture Sensitivity Level 1 must be maintained.

Composition: Thick film construction is required for functional equivalence.

The RMCF0402FT3R01 manufactured by Stackpole Electronics Inc satisfies all substitution criteria while maintaining active product status and full regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the RC1005F3R01CS and RMCF0402FT3R01 are active products with full ROHS3 compliance and identical electrical and mechanical specifications. The RMCF0402FT3R01 carries AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components. The temperature coefficient difference (±300ppm/°C versus ±200ppm/°C) represents improved thermal stability in the Stackpole part. Selection between these parts depends on application requirements: the Samsung part is suitable for general industrial applications, while the Stackpole part is appropriate for automotive and high-reliability applications where AEC-Q200 qualification is specified or preferred.

Frequently Asked Questions (FAQ)

Q: Can RMCF0402FT3R01 be used as a direct replacement for RC1005F3R01CS?

A: Yes. Both parts share identical resistance (3.01 Ohms), tolerance (±1%), power rating (0.063W), package dimensions (0402 / 1005 Metric), and operating temperature range (-55°C to 155°C). Physical and electrical compatibility is confirmed.

Q: What is the significance of the AEC-Q200 rating on the RMCF0402FT3R01?

A: AEC-Q200 is an automotive industry qualification standard. This certification indicates the Stackpole part meets automotive reliability and quality requirements. It is not required for non-automotive applications but provides additional assurance for automotive or high-reliability use cases.

Q: Does the temperature coefficient difference affect substitution eligibility?

A: No. The temperature coefficient (±300ppm/°C for Samsung versus ±200ppm/°C for Stackpole) does not disqualify substitution. The Stackpole part exhibits superior thermal stability. Both values fall within acceptable ranges for 0402 thick film resistors and do not affect mechanical or electrical compatibility.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts are 0.039" L x 0.020" W (1.00mm x 0.50mm) with maximum seated height of 0.016" (0.40mm). PCB footprint and assembly compatibility are identical.

Q: What is Moisture Sensitivity Level 1?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Both parts carry this classification.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RC1005F3R01CS and RMCF0402FT3R01 are ROHS3 compliant, meeting current environmental and hazardous substance restrictions.
