Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM3602F is the direct equivalent substitute for the RK73G1HTTC3602F. Both components are manufactured by KOA Speer Electronics, Inc., and share identical electrical, mechanical, and compliance specifications. The primary distinction is product status: the original part is designated "Not For New Designs," while the substitute maintains active production status.

For applications requiring the 36 kOhms ±1% 0.05W thick film resistor in 0201 package with AEC-Q200 automotive qualification, the RK73G1HTTCM3602F provides full functional and physical compatibility. Both parts maintain ROHS3 compliance, MSL 1 moisture sensitivity rating, and identical temperature performance across the -55°C to 155°C operating range.

The substitute part is suitable for direct replacement in existing designs and is the recommended selection for new production applications where the original part number is specified.

Frequently Asked Questions (FAQ)

Q: Can the RK73G1HTTCM3602F be used as a direct replacement for RK73G1HTTC3602F in automotive applications?

A: Yes. Both parts are electrically and mechanically identical with matching AEC-Q200 automotive qualification. The substitute maintains the same 36 kOhms resistance, ±1% tolerance, 0.05W power rating, 0201 package dimensions, and operating temperature range. No circuit modifications are required.

Q: What is the difference between these two part numbers?

A: The RK73G1HTTCM3602F differs from RK73G1HTTC3602F only in product status. The substitute is actively produced, while the original is classified "Not For New Designs." All technical specifications, performance characteristics, and compliance certifications are identical.

Q: Are both parts suitable for high-temperature automotive environments?

A: Yes. Both the RK73G1HTTC3602F and RK73G1HTTCM3602F operate across -55°C to 155°C with ±50ppm/°C temperature coefficient and maintain AEC-Q200 automotive qualification across this full range.

Q: Does the 0201 package dimension remain consistent between these parts?

A: Yes. Both parts use the identical 0201 (0603 metric) package 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 footprints and assembly processes are interchangeable.

Q: Are both parts RoHS compliant?

A: Yes. Both the RK73G1HTTC3602F and RK73G1HTTCM3602F are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating, meeting current environmental and regulatory requirements.
