Engineering Selection Recommendations

Primary Substitute: RK73H1HTTCM2942F (KOA Speer Electronics, Inc.)

The RK73H1HTTCM2942F is the manufacturer-recommended equivalent from KOA Speer Electronics, Inc. This part maintains identical electrical specifications and package format while carrying an "Active" product status. Selection of this part ensures continuity within the same manufacturer's product line and simplifies supply chain management. All compliance certifications (AEC-Q200, ROHS3, MSL 1) are maintained.

Alternative Substitute: AC0201FR-0729K4L (YAGEO)

The AC0201FR-0729K4L from YAGEO provides a cross-manufacturer equivalent with identical electrical and mechanical parameters. This part is also rated Active and meets all required compliance standards including AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 moisture sensitivity rating. The AC0201FR-0729K4L includes moisture-resistant construction, matching the original part's environmental protection specifications.

Both substitute parts are suitable for direct replacement in applications where the RK73H1HTTC2942F is currently specified, provided that the design does not contain manufacturer-specific constraints or supply agreements.

Frequently Asked Questions (FAQ)

Q: Can the RK73H1HTTCM2942F be used as a direct replacement for the RK73H1HTTC2942F?

A: Yes. The RK73H1HTTCM2942F is the manufacturer-recommended equivalent. Both parts share identical resistance (29.4 kOhms), tolerance (±1%), power rating (0.05W), package format (0201), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), and all compliance certifications (AEC-Q200, ROHS3, MSL 1). The primary difference is product status: RK73H1HTTCM2942F is Active, while RK73H1HTTC2942F is Not For New Designs.

Q: What is the difference between RK73H1HTTC2942F and AC0201FR-0729K4L?

A: Both parts are electrically and mechanically identical in all critical parameters: 29.4 kOhms ±1%, 0.05W power rating, 0201 package, ±200ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. The primary difference is manufacturer: KOA Speer Electronics, Inc. versus YAGEO. Both are AEC-Q200 qualified and ROHS3 compliant. AC0201FR-0729K4L is currently Active in production.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All substitute parts listed (RK73H1HTTCM2942F and AC0201FR-0729K4L) carry AEC-Q200 automotive qualification, meeting the same reliability and qualification standards as the original RK73H1HTTC2942F.

Q: Do the substitute parts have the same moisture resistance properties?

A: RK73H1HTTCM2942F does not specify moisture resistance in the provided data. AC0201FR-0729K4L explicitly includes moisture-resistant construction, matching the original part's specification. All parts maintain MSL 1 (Unlimited) moisture sensitivity level rating.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. All parts share identical package format (0201 / 0603 Metric), physical dimensions (0.024" L x 0.012" W), and height specifications (0.010" max seated height). No PCB layout or footprint modifications are required for substitution.
