Engineering Selection Recommendations

Primary Selection (Manufacturer Recommended): RK73H1HTTCM86R6F from KOA Speer Electronics is the manufacturer-recommended substitute. This variant maintains identical electrical and mechanical specifications to the original RK73H1HTTC86R6F while offering increased inventory availability (1160 units). Both parts share the same series designation (RK73H) and active production status. Selection of this part eliminates cross-manufacturer qualification concerns and maintains supply chain consistency with the original equipment manufacturer.

Alternative Selection (Cross-Manufacturer): AC0201FR-0786R6L from YAGEO provides direct functional equivalence with full AEC-Q200 automotive compliance and RoHS3 certification. This part meets all electrical specifications (86.6 Ohms ±1%, 0.05W, ±200ppm/°C) and mechanical requirements (0201 package, identical dimensions). The YAGEO AC series is established in automotive applications with equivalent moisture-resistant thick film construction. This option is suitable when KOA supply is constrained or when multi-source qualification is required.

Compliance Verification: All three parts maintain active production status, AEC-Q200 automotive qualification, RoHS3 compliance, and MSL 1 moisture sensitivity rating. Operating temperature ranges (-55°C to 155°C) and physical dimensions are identical across all options, ensuring direct PCB compatibility without layout modifications.
