Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73G1HTTC1001F is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (1 kOhms), tolerance (±1%), power rating (0.05W), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C ~ 155°C) must be identical.

Mechanical Parameters: Package format (0201), 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.

Compliance Parameters: Automotive AEC-Q200 qualification, ROHS3 compliance, and Moisture Sensitivity Level 1 classification are mandatory for substitution in automotive applications.

Material Composition: Thick film construction is required to maintain performance characteristics.

The substitute part RK73G1HTTCM1001F meets all these criteria and represents a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM1001F is the primary substitute for RK73G1HTTC1001F based on the following engineering criteria:

Product Status Alignment: The substitute part carries Active product status, whereas the main part is designated Not For New Designs. This status difference is the primary driver for substitution in ongoing production and new design implementations.

Compliance Equivalence: Both parts maintain identical AEC-Q200 automotive qualification, ROHS3 compliance, and REACH unaffected status. No compliance gaps exist between the two parts.

Electrical and Mechanical Identity: All specified electrical parameters (resistance, tolerance, power rating, temperature coefficient, operating range) and mechanical parameters (package, dimensions, terminations) are identical. Direct pin-for-pin and functional substitution is supported.

Series Continuity: Both parts belong to the RK73G series from KOA Speer Electronics, Inc., ensuring manufacturing consistency and supply chain reliability.

For applications requiring the RK73G1HTTC1001F, transition to RK73G1HTTCM1001F is supported without circuit redesign or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM1001F be used as a direct replacement for RK73G1HTTC1001F in automotive applications?

A: Yes. Both parts are AEC-Q200 qualified with identical electrical specifications (1 kOhms ±1%, 0.05W, ±50ppm/°C) and mechanical packaging (0201 format). Direct substitution is supported without circuit modification.

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

A: This designation indicates the RK73G1HTTC1001F is in mature or end-of-life phase. The RK73G1HTTCM1001F, with Active status, is the recommended part for new designs and ongoing production to ensure long-term supply availability.

Q: Are there any differences in package or physical dimensions between these parts?

A: No. Both parts use identical 0201 (0603 Metric) packaging with dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm). PCB layout and assembly processes require no modification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry AEC-Q200 automotive qualification. Moisture Sensitivity Level 1 (Unlimited) applies to both, indicating no special handling requirements.

Q: What is the temperature coefficient specification, and does it differ between the parts?

A: Both parts specify ±50ppm/°C temperature coefficient across the -55°C to 155°C operating range. Temperature stability performance is identical.

Q: Is the thick film composition consistent between both parts?

A: Yes. Both parts use thick film construction, ensuring consistent performance characteristics, frequency response, and noise performance in circuit applications.
