Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM2003F be used as a direct replacement for RK73H1HTTC2003F?

A: Yes. Both parts are manufactured by KOA Speer Electronics, Inc., share identical electrical specifications (200 kOhms ±1%, 0.05W), operate across -55°C to 155°C, meet AEC-Q200 automotive standards, and use the same 0201 package. The primary difference is product status: RK73H1HTTCM2003F is Active while RK73H1HTTC2003F is Not For New Designs.

Q: Is AC0201FR-07200KL compatible with designs using RK73H1HTTC2003F?

A: Yes. AC0201FR-07200KL meets all electrical and mechanical parameters: 200 kOhms ±1%, 0.05W power rating, 0201 package, ±200ppm/°C temperature coefficient, -55°C to 155°C operating range, AEC-Q200 qualification, and RoHS3 compliance. Cross-manufacturer substitution is valid based on parameter equivalence.

Q: What determines if a part can substitute for RK73H1HTTC2003F?

A: Substitution requires exact matching of: resistance value (200 kOhms), tolerance (±1%), power rating (0.05W), package type (0201), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C to 155°C), AEC-Q200 rating, moisture resistance, RoHS3 compliance, and MSL 1 rating. All identified substitutes meet these criteria.

Q: Are there packaging differences between these parts?

A: All three parts use identical 0201 (0603 Metric) packaging with dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm). They are mechanically interchangeable on PCBs designed for 0201 components.

Q: Do these substitutes maintain automotive qualification?

A: Yes. All substitute parts carry AEC-Q200 automotive qualification, matching the original RK73H1HTTC2003F specification. They are suitable for automotive applications requiring this certification level.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity limitations. These parts do not require special moisture-controlled storage or handling procedures, simplifying inventory management and reducing shelf-life constraints.
