Engineering Selection Recommendations

For Automotive Applications with AEC-Q200 Requirement:

RK73H1HTTCM3320F is the primary recommended substitute. This part maintains manufacturer continuity with KOA Speer Electronics, Inc., carries Active product status suitable for new designs, and retains full AEC-Q200 automotive qualification. The part is functionally equivalent to the original RK73H1HTTC3320F across all critical electrical and mechanical parameters.

AC0201FR-07332RL from YAGEO provides an alternative from an established automotive-qualified manufacturer. This part meets all electrical specifications, maintains AEC-Q200 compliance, includes moisture-resistant construction, and carries Active product status. Selection of this substitute is appropriate when YAGEO supply chain or inventory availability is preferred.

For Applications Where AEC-Q200 is Not Mandatory:

CRCW0201332RFNED from Vishay Dale offers equivalent electrical and mechanical specifications with Active product status and ROHS3 compliance. This part is suitable for non-automotive applications or where automotive qualification is not a design requirement. Note that AEC-Q200 rating is not specified for this component.

All three substitute parts are ROHS3 compliant, REACH Unaffected, and classified as EAR99, maintaining regulatory alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Can RK73H1HTTCM3320F be used as a direct replacement for RK73H1HTTC3320F in automotive circuits?

A: Yes. RK73H1HTTCM3320F is electrically and mechanically equivalent to RK73H1HTTC3320F. Both parts share identical resistance (332 Ohms), tolerance (±1%), power rating (0.05W), package (0201), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. The primary difference is product status: RK73H1HTTCM3320F is Active, making it suitable for new designs.

Q: What is the difference between RK73H1HTTC3320F and RK73H1HTTCM3320F?

A: The main difference is product status. RK73H1HTTC3320F is marked Not For New Designs, while RK73H1HTTCM3320F is Active. Both parts are manufactured by KOA Speer Electronics, Inc., and share identical electrical specifications, package dimensions, and automotive compliance ratings. The "M" designation in RK73H1HTTCM3320F indicates a variant within the same product family.

Q: Are YAGEO AC0201FR-07332RL and Vishay Dale CRCW0201332RFNED suitable for automotive applications?

A: AC0201FR-07332RL from YAGEO is suitable for automotive applications. This part carries AEC-Q200 qualification and moisture-resistant construction. CRCW0201332RFNED from Vishay Dale meets all electrical and mechanical specifications but does not specify AEC-Q200 rating. For automotive applications requiring AEC-Q200 compliance, AC0201FR-07332RL is the appropriate choice among cross-manufacturer alternatives.

Q: Do all substitute parts have the same physical dimensions?

A: Yes. All substitute parts—RK73H1HTTCM3320F, AC0201FR-07332RL, and CRCW0201332RFNED—share identical package specifications: 0201 (0603 Metric) with dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm). These parts are physically interchangeable on PCBs designed for 0201 package components.

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

A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and does not require special moisture control during storage or handling. All identified substitute parts carry this rating, ensuring no additional moisture management procedures are necessary compared to the original RK73H1HTTC3320F.

Q: Can I substitute CRCW0201332RFNED in place of RK73H1HTTC3320F in all applications?

A: CRCW0201332RFNED is electrically and mechanically equivalent and suitable for general applications. However, for automotive circuits specifically requiring AEC-Q200 compliance, this part is not recommended because AEC-Q200 rating is not specified. For non-automotive or applications where automotive qualification is not mandated, CRCW0201332RFNED provides a valid alternative with Active product status and full ROHS3 compliance.

Q: Are there any differences in temperature coefficient among the substitute parts?

A: No. All substitute parts—RK73H1HTTC3320F, RK73H1HTTCM3320F, AC0201FR-07332RL, and CRCW0201332RFNED—share an identical temperature coefficient of ±200ppm/°C and operating temperature range of -55°C ~ 155°C. Temperature stability characteristics are equivalent across all parts.
