Engineering Selection Recommendations

Primary Recommendation: RK73H1HTTCM8062F

The RK73H1HTTCM8062F is the manufacturer-recommended substitute from KOA Speer Electronics, Inc. This part carries Active product status, indicating ongoing manufacturing and supply support. It maintains identical electrical and mechanical specifications to the original RK73H1HTTC8062F while providing current availability. Selection of this part eliminates supply chain risk associated with obsolete components.

Secondary Recommendation: AC0201FR-0780K6L

The AC0201FR-0780K6L from YAGEO is a cross-manufacturer equivalent meeting all electrical and mechanical requirements. This part is Active and maintains full AEC-Q200 automotive qualification, ROHS3 compliance, and moisture resistance specifications. Cross-manufacturer substitution is valid when supply constraints exist for the primary KOA option.

Both substitute parts are suitable for direct replacement in automotive applications requiring AEC-Q200 qualification and moisture-resistant thick film resistors in the 0201 package.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM8062F be used as a direct replacement for RK73H1HTTC8062F?

A: Yes. Both parts are manufactured by KOA Speer Electronics, Inc., and share identical electrical specifications (80.6 kOhms ±1%, 0.05W), physical dimensions (0201 package), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), and automotive qualifications (AEC-Q200). The primary difference is product status: RK73H1HTTCM8062F is Active, while the original is Not For New Designs.

Q: Is AC0201FR-0780K6L compatible with circuits designed for RK73H1HTTC8062F?

A: Yes. AC0201FR-0780K6L from YAGEO meets all critical electrical and mechanical parameters: 80.6 kOhms ±1%, 0.05W power rating, 0201 package, ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range, AEC-Q200 automotive rating, and moisture resistance. Cross-manufacturer substitution is valid based on parameter equivalence.

Q: What are the key parameters that determine substitution validity?

A: Substitution validity is determined by matching: resistance value (80.6 kOhms), tolerance (±1%), power rating (0.05W), package type (0201), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), automotive qualification (AEC-Q200), moisture resistance, RoHS compliance (ROHS3), and Moisture Sensitivity Level (1).

Q: Are there packaging differences between substitute parts?

A: RK73H1HTTC8062F and AC0201FR-0780K6L are both supplied in Tape & Reel (TR) packaging. RK73H1HTTCM8062F packaging type is not specified in available documentation. Verify packaging requirements with your procurement department before finalizing orders.

Q: Why is RK73H1HTTC8062F marked as "Not For New Designs"?

A: This designation indicates the part has been superseded by newer alternatives. For new circuit designs, KOA Speer Electronics, Inc. recommends using RK73H1HTTCM8062F, which maintains identical specifications while offering active product status and ongoing manufacturing support.
