Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F5R11CS is determined by strict equivalence across the following parameters:

Electrical Parameters: Resistance value (5.11 Ohms), tolerance (±1%), and power rating (0.063W / 1/16W) must be identical.

Mechanical Parameters: Package designation (0402 / 1005 Metric), physical dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm), and maximum seated height (0.016" / 0.40mm) must match exactly.

Material Specification: Thick film composition is required.

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

Termination Count: Two terminations are required.

The RMCF0402FT5R11 from Stackpole Electronics Inc meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The RMCF0402FT5R11 from Stackpole Electronics Inc is a qualified substitute for the RC1005F5R11CS. Both components maintain identical electrical specifications (5.11 Ohms ±1%, 0.063W), mechanical dimensions (0402 package), and compliance certifications (ROHS3, REACH Unaffected, EAR99).

The Stackpole part demonstrates a superior temperature coefficient specification (±200ppm/°C versus ±300ppm/°C), indicating tighter performance stability across temperature variations. The RMCF0402FT5R11 carries AEC-Q200 automotive qualification, which represents an enhanced reliability standard applicable to automotive and high-reliability applications.

Both parts are Active status products with unlimited moisture sensitivity level (MSL 1), ensuring compatibility in standard storage and handling environments. Selection between these parts should be based on application requirements: the Samsung RC1005F5R11CS for general-purpose applications, or the Stackpole RMCF0402FT5R11 for automotive-grade or temperature-critical applications requiring superior temperature coefficient performance.

Frequently Asked Questions (FAQ)

Q: Can the RMCF0402FT5R11 be used as a direct replacement for the RC1005F5R11CS in existing designs?

A: Yes. Both parts share identical resistance (5.11 Ohms), tolerance (±1%), power rating (0.063W), package format (0402), and operating temperature range (-55°C to 155°C). Physical dimensions and termination count are equivalent, allowing direct PCB footprint compatibility.

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

A: AEC-Q200 is an automotive industry qualification standard that certifies component reliability under automotive operating conditions. This certification is not present on the Samsung part but does not prevent substitution; it indicates the Stackpole part meets additional reliability requirements suitable for automotive applications.

Q: Does the temperature coefficient difference affect substitution eligibility?

A: No. The temperature coefficient (±300ppm/°C for Samsung, ±200ppm/°C for Stackpole) represents a performance characteristic, not a substitution barrier. The Stackpole specification is superior, providing tighter tolerance maintenance across temperature variations. Both values fall within acceptable ranges for 0402 thick film resistors.

Q: Are packaging and tape specifications identical?

A: Both parts are supplied in Tape & Reel (TR) format with 0402 package designation. Physical dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm) and maximum seated height (0.016" / 0.40mm) are identical, ensuring compatibility with standard pick-and-place equipment and PCB assembly processes.

Q: What compliance certifications apply to both parts?

A: Both RC1005F5R11CS and RMCF0402FT5R11 are ROHS3 compliant, REACH Unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0030. Moisture sensitivity level is 1 (Unlimited) for both, indicating no special storage or handling requirements.

Q: Can these parts be intermixed in the same production batch?

A: Yes. Identical electrical and mechanical specifications permit intermixing in production environments. However, component traceability documentation should reflect the specific manufacturer and part number used in each assembly instance for warranty and quality assurance purposes.
