Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM6342F be used as a direct replacement for RK73H1HTTC6342F?

A: Yes. The RK73H1HTTCM6342F is the manufacturer-recommended substitute from KOA Speer Electronics, Inc. It matches all electrical parameters (63.4 kOhms ±1%, 0.05W), package configuration (0201), temperature specifications (-55°C ~ 155°C), and automotive qualifications (AEC-Q200). The primary advantage is its Active product status, ensuring long-term availability.

Q: Is AC0201FR-0763K4L from YAGEO compatible with designs using RK73H1HTTC6342F?

A: Yes. The AC0201FR-0763K4L meets all mandatory electrical and mechanical specifications. It provides identical resistance (63.4 kOhms ±1%), power rating (0.05W), package size (0201), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), and automotive qualification (AEC-Q200). Both parts are moisture-resistant and ROHS3 compliant.

Q: What is the significance of the "Not For New Designs" status on RK73H1HTTC6342F?

A: This status indicates the part has been superseded and is no longer recommended for new product development. Existing designs may continue using available inventory, but new designs should transition to active alternatives such as RK73H1HTTCM6342F or AC0201FR-0763K4L to ensure long-term supply chain stability.

Q: Are there any differences in moisture sensitivity between the substitute parts?

A: No. All three parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture baking requirements. This specification is consistent across RK73H1HTTC6342F, RK73H1HTTCM6342F, and AC0201FR-0763K4L.

Q: Can these parts be used interchangeably in automotive applications?

A: Yes. All three parts are AEC-Q200 qualified, meeting automotive industry reliability and qualification standards. They are suitable for automotive circuit applications requiring 63.4 kOhms ±1% resistors in 0201 package format with -55°C ~ 155°C operating range.

Q: What packaging format is available for these substitutes?

A: RK73H1HTTC6342F and AC0201FR-0763K4L are supplied in Tape & Reel (TR) format. RK73H1HTTCM6342F packaging information is not specified in available data. Confirm packaging requirements with supplier documentation before procurement.
