Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM3002F is the direct equivalent substitute for RK73G1HTTC3002F. Both parts are manufactured by KOA Speer Electronics, Inc., within the RK73G series, and maintain identical electrical, mechanical, and compliance specifications.

Selection Basis:

The primary distinction between the main part and substitute is product lifecycle status. The RK73G1HTTC3002F carries "Not For New Designs" designation, indicating end-of-life or transition status. The RK73G1HTTCM3002F maintains "Active" status, confirming ongoing manufacturing support and availability.

Both parts satisfy automotive AEC-Q200 qualification requirements and ROHS3 compliance mandates. The identical temperature coefficient (±50ppm/°C), operating temperature range (-55°C ~ 155°C), and moisture sensitivity classification (MSL 1) ensure functional equivalence in all specified operating conditions.

For applications requiring the 30 kOhms ±1% 0.05W 0201 package thick film resistor with automotive qualification, the RK73G1HTTCM3002F provides full electrical and mechanical compatibility with established design specifications.

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM3002F be used as a direct replacement for RK73G1HTTC3002F in existing designs?

A: Yes. The RK73G1HTTCM3002F is a direct equivalent substitute. All electrical parameters (resistance, tolerance, power rating, temperature coefficient), mechanical dimensions (0201 package, 0.024" x 0.012"), and compliance certifications (AEC-Q200, ROHS3) are identical. No circuit redesign or validation is required.

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

A: This designation indicates the RK73G1HTTC3002F is in end-of-life transition. Existing inventory may be available, but the manufacturer does not recommend this part for new product development. The RK73G1HTTCM3002F, classified as "Active," is the recommended alternative for new designs and ongoing production.

Q: Are the physical dimensions and package specifications identical?

A: Yes. Both parts use the 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 identical.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both RK73G1HTTC3002F and RK73G1HTTCM3002F are AEC-Q200 qualified, meeting automotive industry reliability and performance standards. Both are ROHS3 compliant and carry MSL 1 (unlimited moisture sensitivity level).

Q: Is there any difference in temperature performance between the two parts?

A: No. Both parts have identical temperature coefficient (±50ppm/°C) and operating temperature range (-55°C ~ 155°C). Performance across the full automotive temperature spectrum is equivalent.

Q: What is the difference between the part numbers RK73G1HTTC3002F and RK73G1HTTCM3002F?

A: The part numbers differ only in the suffix designation (C vs. CM). This variation reflects internal KOA Speer Electronics manufacturing or packaging code changes. All functional and electrical specifications remain identical. The CM variant represents the current active production version.
