Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM6800F serves as the active equivalent to the RK73G1HTTC6800F. Both parts are manufactured by KOA Speer Electronics, Inc., within the RK73G series, and maintain identical electrical, mechanical, and compliance specifications. The primary distinction is product status: the original part is designated "Not For New Designs," while the substitute is classified as "Active."

For applications requiring the 680 Ohm ±1% 0.05W thick film chip resistor in 0201 package with AEC-Q200 automotive qualification, the RK73G1HTTCM6800F provides full functional and physical compatibility. Both parts satisfy ROHS3 compliance and maintain unlimited moisture sensitivity rating (MSL 1).

Selection between these parts should be based on supply chain availability and design phase requirements. The active status of RK73G1HTTCM6800F ensures continued manufacturer support and long-term availability for production applications.

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM6800F be used as a direct replacement for RK73G1HTTC6800F?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance (680 Ohms ±1%), power rating (0.05W), package (0201), temperature coefficient (±50ppm/°C), and operating range (-55°C ~ 155°C). Both carry AEC-Q200 automotive qualification and ROHS3 compliance.

Q: What is the significance of the "Not For New Designs" status on the original part?
