Key Parameters

Substitute Part Grouping Explanation

Substitution of the RK73G1HTTC6200F is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (620 Ohms), tolerance (±1%), and power rating (0.05W) must be identical. Temperature coefficient (±50ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Specifications: Package type (0201 / 0603 Metric), physical dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm), and seated height (0.010" / 0.26mm maximum) ensure PCB compatibility and assembly process compatibility.

Compliance & Ratings: AEC-Q200 automotive qualification, ROHS3 compliance, and Moisture Sensitivity Level 1 are mandatory for equivalent substitution in automotive applications.

Composition: Thick film construction must be maintained to preserve electrical performance characteristics.

Parts meeting all these criteria are classified as direct equivalents and may be substituted without circuit redesign or validation.

Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM6200F is a direct electrical and mechanical equivalent to the RK73G1HTTC6200F. Both components are manufactured by KOA Speer Electronics, Inc., within the RK73G series, and share identical specifications across all critical parameters: 620 Ohm resistance, ±1% tolerance, 0.05W power rating, 0201 package, ±50ppm/°C temperature coefficient, and -55°C ~ 155°C operating range.

The primary distinction is product status: the main part (RK73G1HTTC6200F) is classified as "Not For New Designs," while the substitute (RK73G1HTTCM6200F) maintains "Active" status. Both parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and Moisture Sensitivity Level 1 rating, ensuring continued suitability for automotive applications.

The RK73G1HTTCM6200F is the recommended substitute for applications requiring an active-status component with identical electrical performance and automotive compliance.

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM6200F be used as a direct replacement for RK73G1HTTC6200F?

A: Yes. Both components are electrically and mechanically identical across all specified parameters, including resistance value, tolerance, power rating, package type, temperature coefficient, and operating temperature range. Both maintain AEC-Q200 automotive qualification and ROHS3 compliance.

Q: What is the significance of the product status difference?

A: The main part (RK73G1HTTC6200F) is designated "Not For New Designs," indicating it is in end-of-life status. The substitute (RK73G1HTTCM6200F) is classified as "Active," meaning it is currently in production and available for new applications. For ongoing production and new designs, the active substitute is the appropriate selection.

Q: Are there any package or assembly compatibility differences?

A: No. Both components use the identical 0201 (0603 Metric) package with matching physical dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm) and seated height (0.010" / 0.26mm maximum). Assembly processes and PCB layouts require no modification.

Q: Do both parts meet automotive compliance requirements?

A: Yes. Both the RK73G1HTTC6200F and RK73G1HTTCM6200F are AEC-Q200 qualified, ROHS3 compliant, and rated at Moisture Sensitivity Level 1 (Unlimited). They are suitable for automotive applications without additional qualification.

Q: What is the difference between the part numbers?

A: The part numbers differ only in the suffix: RK73G1HTTC6200F versus RK73G1HTTCM6200F. This suffix variation reflects internal KOA Speer Electronics manufacturing or packaging designation but does not indicate functional or electrical differences. All specified electrical and mechanical parameters remain identical.
