Parameter Comparison

Engineering Selection Recommendations

The RK73B1HTTCM103G is the direct equivalent substitute for the RK73B1HTTC103G. Both components are manufactured by KOA Speer Electronics, Inc., within the RK73B series, and share identical electrical, mechanical, and compliance specifications. The primary distinction is product status: the original part is classified as "Not For New Designs," while the substitute part maintains Active status with higher inventory availability (991 Pcs vs. 644 Pcs).

For applications requiring the 10 kOhms ±2% 0.05W thick film resistor in 0201 package with AEC-Q200 automotive qualification, the RK73B1HTTCM103G provides full functional and regulatory equivalence. Both parts satisfy ROHS3 compliance, MSL 1 moisture sensitivity, and identical operating temperature specifications (-55°C ~ 155°C).

Frequently Asked Questions (FAQ)

Q: Can RK73B1HTTCM103G be used as a direct replacement for RK73B1HTTC103G?

A: Yes. Both parts are electrically and mechanically identical with matching resistance (10 kOhms ±2%), power rating (0.05W), package dimensions (0201), and automotive certifications (AEC-Q200). The substitute part is the recommended selection for new procurement due to its Active product status.

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

A: This designation indicates the RK73B1HTTC103G is in end-of-life phase and not recommended for new product development. The RK73B1HTTCM103G, with Active status, is the supported alternative for ongoing and future applications.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components measure 0.024" L x 0.012" W (0.60mm x 0.30mm) with a maximum seated height of 0.010" (0.26mm), ensuring identical PCB footprint compatibility.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the RK73B1HTTC103G and RK73B1HTTCM103G are AEC-Q200 qualified, meeting automotive industry reliability and performance standards.

Q: Is there a difference in packaging format between these parts?

A: The main part specifies Tape & Reel (TR) packaging. The substitute part packaging information is not specified in available data. Confirm packaging requirements with your supplier for procurement purposes.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0030. Moisture sensitivity level is MSL 1 (Unlimited) for both components.
