Key Parameters

Substitute Part Grouping Explanation

Substitution of the RK73G1HTTC2000F is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (200 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 Parameters: 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) must match exactly to ensure PCB compatibility and assembly process compatibility.

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

Series Continuity: Both parts belong to the RK73G series, confirming design family equivalence.

The substitute part RK73G1HTTCM2000F meets all these criteria and is classified as "Active" product status, making it suitable for new production and design continuity.

Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM2000F is the direct equivalent substitute for the RK73G1HTTC2000F. Both parts are manufactured by KOA Speer Electronics, Inc., and share identical electrical specifications, mechanical dimensions, and automotive compliance certifications.

The primary distinction is product status: the original part (RK73G1HTTC2000F) is designated "Not For New Designs," while the substitute (RK73G1HTTCM2000F) maintains "Active" status. This status difference reflects manufacturing lifecycle management and does not indicate any technical deficiency in the original part. The substitute part is suitable for new production designs, ongoing manufacturing, and field replacement applications where the RK73G1HTTC2000F was previously specified.

Both parts satisfy AEC-Q200 automotive qualification requirements, ROHS3 environmental compliance, and MSL 1 moisture sensitivity ratings. Electrical performance, thermal characteristics, and mechanical compatibility are fully equivalent across all provided specifications.

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM2000F be used as a direct replacement for RK73G1HTTC2000F in existing designs?

A: Yes. The substitute part is electrically and mechanically identical. All critical parameters—resistance, tolerance, power rating, package dimensions, temperature range, and automotive certifications—are equivalent. Direct substitution is valid for PCB assembly, rework, and field replacement applications.

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

A: This designation indicates the part has reached end-of-life in the manufacturer's product lifecycle. It does not reflect performance degradation or technical obsolescence. The substitute part (RK73G1HTTCM2000F) with "Active" status should be used for new production designs to ensure long-term supply continuity.

Q: Are the package and physical dimensions identical between these parts?

A: Yes. Both parts use the 0201 (0603 Metric) package with identical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm). PCB footprints and assembly processes are fully compatible.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both RK73G1HTTC2000F and RK73G1HTTCM2000F are AEC-Q200 qualified, confirming suitability for automotive applications. Both maintain ROHS3 compliance and MSL 1 moisture sensitivity ratings.

Q: Is there any difference in thermal performance between these parts?

A: No. Both parts have identical temperature coefficients (±50ppm/°C) and operating temperature ranges (-55°C ~ 155°C). Thermal behavior and stability are equivalent.

Q: What is the difference between the part numbers RK73G1HTTC2000F and RK73G1HTTCM2000F?

A: The parts belong to the same RK73G series and share the same base specifications. The suffix variation (C vs. CM) reflects internal manufacturer coding for product lifecycle management. This does not indicate functional or performance differences.
