Engineering Selection Recommendations

RK73H1HTTCM1603F (KOA Speer Electronics, Inc.): This part is the manufacturer-recommended substitute from KOA Speer Electronics, Inc. It maintains identical electrical and mechanical specifications to the RK73H1HTTC1603F while carrying an Active product status. This part is suitable for new production runs and ongoing applications requiring the same performance characteristics. The part is ROHS3 compliant and maintains full AEC-Q200 automotive qualification.

AC0201FR-07160KL (YAGEO): This part is a direct cross-reference from YAGEO and meets all electrical, mechanical, and compliance requirements of the RK73H1HTTC1603F. The AC0201FR-07160KL carries an Active product status and is available in Tape & Reel packaging. This part is suitable for applications where multi-source component qualification is required or where YAGEO supply chain availability is preferred. Full AEC-Q200 automotive qualification and ROHS3 compliance are maintained.

Both substitute parts are electrically and mechanically interchangeable with the RK73H1HTTC1603F and support the same operating conditions, temperature ranges, and automotive reliability standards.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM1603F be used as a direct replacement for RK73H1HTTC1603F?

A: Yes. The RK73H1HTTCM1603F is the manufacturer-recommended substitute from KOA Speer Electronics, Inc. Both parts share identical electrical specifications (160 kOhms ±1%, 0.05W), mechanical 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: RK73H1HTTCM1603F is Active, while RK73H1HTTC1603F is Not For New Designs.

Q: Is AC0201FR-07160KL compatible with RK73H1HTTC1603F?

A: Yes. The AC0201FR-07160KL from YAGEO meets all electrical and mechanical specifications required for substitution. Both parts are 160 kOhms ±1%, 0.05W, 0201 package, with ±200ppm/°C temperature coefficient and -55°C ~ 155°C operating range. Both carry AEC-Q200 automotive qualification and ROHS3 compliance. The AC0201FR-07160KL is an Active product available in Tape & Reel packaging.

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters match exactly: resistance value (160 kOhms), tolerance (±1%), power rating (0.05W), package type (0201), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), AEC-Q200 rating, and RoHS compliance status. All three parts listed meet these criteria.

Q: Does packaging format affect substitution?

A: Packaging format (Tape & Reel vs. other formats) does not affect electrical or mechanical compatibility. However, supply chain and handling procedures may differ. Both RK73H1HTTC1603F and AC0201FR-07160KL are supplied in Tape & Reel format. Verify packaging requirements with your procurement process before finalizing part selection.

Q: Are all substitute parts automotive-qualified?

A: Yes. All substitute parts listed (RK73H1HTTCM1603F and AC0201FR-07160KL) carry AEC-Q200 automotive qualification, matching the original RK73H1HTTC1603F specification. This qualification is maintained across all substitute options.

Q: What is the moisture sensitivity level for these parts?

A: All parts, including the main part and substitutes, have a Moisture Sensitivity Level (MSL) rating of 1 (Unlimited). This indicates no moisture sensitivity restrictions and no special storage or handling requirements.
