Parameter Comparison

Engineering Selection Recommendations

The RMCF2512FT6K98 is a direct functional equivalent to the RC6432F6981CS. Both components are active production parts with ROHS3 compliance and identical electrical performance specifications. The Stackpole Electronics Inc RMCF2512FT6K98 carries AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components. The maximum seated height differential of 0.002" (0.04mm) between the two parts remains within standard PCB assembly tolerances and does not impact circuit performance or board layout compatibility. Selection between these parts depends on application requirements: the Samsung RC6432F6981CS for general industrial applications, or the Stackpole RMCF2512FT6K98 for automotive and mission-critical applications requiring AEC-Q200 certification.

Frequently Asked Questions (FAQ)

Q: Can the RMCF2512FT6K98 replace the RC6432F6981CS in existing designs?

A: Yes. Both components share identical electrical specifications (6.98 kOhms ±1%, 1W, ±100ppm/°C), identical package dimensions (2512/6432 Metric), and equivalent compliance ratings (ROHS3, MSL 1). The 0.002" height difference is within standard PCB assembly tolerances.

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

A: AEC-Q200 is an automotive industry qualification standard. The RMCF2512FT6K98 meets enhanced reliability and testing requirements for automotive applications. This certification is not present on the Samsung RC6432F6981CS, making the Stackpole part preferable for automotive or safety-critical designs.

Q: Are there any moisture handling differences between these parts?

A: No. Both components carry MSL 1 (Unlimited) ratings, indicating identical moisture sensitivity levels and equivalent handling, storage, and reflow requirements.

Q: Do these parts have different packaging formats?

A: The RC6432F6981CS is supplied in standard packaging, while the RMCF2512FT6K98 is supplied in Cut Tape (CT) format. Both use the identical 2512 (6432 Metric) component package. Packaging format affects tape reel configuration and automated assembly compatibility, not component performance.

Q: What is the temperature performance equivalence?

A: Both parts operate identically across -55°C to 155°C with ±100ppm/°C temperature coefficient. No performance differentiation exists across the specified operating range.

Q: Are there compliance or export considerations when substituting?

A: Both components share identical ECCN (EAR99), HTSUS (8533.21.0030), REACH (Unaffected), and RoHS3 compliance classifications. No additional compliance documentation or export licensing changes are required when substituting between these parts.
