Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM3092F be used as a direct replacement for RK73H1HTTC3092F?

A: Yes. RK73H1HTTCM3092F is the manufacturer-recommended substitute and maintains identical electrical specifications (30.9 kOhms ±1%, 0.05W), mechanical package (0201), temperature performance (±200ppm/°C, -55°C ~ 155°C), and automotive certifications (AEC-Q200). No design changes are required.

Q: What is the difference between RK73H1HTTC3092F and RK73H1HTTCM3092F?

A: The primary difference is product status. RK73H1HTTC3092F is marked "Not For New Designs," while RK73H1HTTCM3092F is "Active." Both parts are electrically and mechanically identical. The "M" designation in RK73H1HTTCM3092F indicates the active production variant.

Q: Can YAGEO AC0201FR-0730K9L replace KOA Speer RK73H1HTTC3092F?

A: Yes. AC0201FR-0730K9L meets all electrical and mechanical requirements: 30.9 kOhms ±1%, 0.05W power rating, 0201 package, ±200ppm/°C temperature coefficient, -55°C ~ 155°C operating range, AEC-Q200 rating, and moisture-resistant thick film construction. Cross-manufacturer substitution is valid when both parts satisfy identical parameter specifications.

Q: Are there packaging differences between these substitute parts?

A: No. All three parts use the 0201 (0603 Metric) surface mount package with identical physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm). Board layout and pick-and-place programming require no modification.

Q: Do these substitutes maintain AEC-Q200 automotive qualification?

A: Yes. All substitute parts carry AEC-Q200 automotive rating and moisture-resistant thick film construction. RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity are maintained across all options.

Q: Which substitute should be selected for new production?

A: RK73H1HTTCM3092F is the preferred choice as the manufacturer-recommended active replacement. AC0201FR-0730K9L is suitable when cross-manufacturer sourcing is required or when YAGEO components are already qualified in the supply chain.
