Parameter Comparison

Engineering Selection Recommendations

Both the RK73H2HTTE8R20F and AC2010FK-078R2L are active production components with identical electrical specifications and automotive compliance certifications. Selection between these parts may be based on inventory availability, supply chain considerations, or PCB assembly height constraints. The AC2010FK-078R2L exhibits a maximum seated height of 0.026" (0.65mm) compared to 0.028" (0.70mm) for the RK73H2HTTE8R20F, which may be relevant for applications with strict height limitations. Both parts maintain ROHS3 compliance and AEC-Q200 automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can AC2010FK-078R2L be used as a direct replacement for RK73H2HTTE8R20F?

A: Yes. Both parts share identical resistance, tolerance, power rating, package format, temperature coefficient, operating temperature range, and automotive compliance ratings. The physical dimensions are equivalent within standard manufacturing tolerances.

Q: Are there differences in physical dimensions between these parts?

A: Both parts use the 2010 (5025 Metric) package with identical length and width of 0.197" x 0.098" (5.00mm x 2.50mm). The maximum seated height differs slightly: RK73H2HTTE8R20F at 0.028" (0.70mm) and AC2010FK-078R2L at 0.026" (0.65mm). This minor difference is within standard PCB assembly tolerances for most applications.

Q: Do both parts meet automotive standards?

A: Yes. Both the RK73H2HTTE8R20F and AC2010FK-078R2L are AEC-Q200 qualified and suitable for automotive applications requiring moisture-resistant thick film resistors.

Q: What is the significance of Moisture Sensitivity Level 1?

A: MSL 1 indicates unlimited shelf life without moisture absorption concerns, eliminating the need for special storage or baking procedures prior to assembly.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant and meet environmental regulatory requirements for electronic component manufacturing and distribution.
