Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73G1HTTC1002F is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (10 kOhms), tolerance (±1%), power rating (0.05W), and temperature coefficient (±50ppm/°C) must be identical. Operating temperature range must encompass or equal -55°C ~ 155°C.

Mechanical Specifications: Package type must be 0201 (0603 Metric) with matching physical dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm) and maximum seated height (0.010" / 0.26mm).

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

Composition: Thick film construction must be maintained to ensure thermal and frequency response characteristics.

Substitute parts must originate from the same manufacturer series (RK73G) or equivalent automotive-qualified series to ensure process consistency and reliability.

Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM1002F is the direct equivalent substitute for the RK73G1HTTC1002F. Both components are manufactured by KOA Speer Electronics, Inc., within the same RK73G series and share identical electrical, mechanical, and compliance specifications.

The primary distinction is product status: RK73G1HTTC1002F is classified as "Not For New Designs," while RK73G1HTTCM1002F maintains "Active" status. For new design implementations and ongoing production requirements, RK73G1HTTCM1002F is the appropriate selection.

Both parts satisfy automotive AEC-Q200 qualification requirements, ROHS3 compliance, and unlimited moisture sensitivity classification (MSL 1), making them suitable for automotive circuit applications requiring 10 kOhms ±1% resistance in a 0201 package.

The substitute part is available with 725 pieces in current inventory, ensuring supply continuity for production and design transitions.

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM1002F be used as a direct replacement for RK73G1HTTC1002F in existing designs?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance (10 kOhms ±1%), power rating (0.05W), package (0201), temperature range (-55°C ~ 155°C), and automotive AEC-Q200 qualification. Pin-to-pin and footprint compatibility is complete.

Q: What is the significance of the "Not For New Designs" status on RK73G1HTTC1002F?

A: This designation indicates the part is in mature or end-of-life phase. While existing inventory remains available, KOA Speer Electronics recommends using RK73G1HTTCM1002F for new design implementations to ensure long-term supply availability and continued manufacturer support.

Q: Are there any thermal or frequency response differences between these two parts?

A: No. Both components share identical composition (thick film), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C ~ 155°C). Thermal and frequency characteristics are equivalent.

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

A: Yes. Both parts conform to 0201 (0603 Metric) package specifications 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 are identical.

Q: Are both parts compliant with automotive and environmental regulations?

A: Yes. Both RK73G1HTTC1002F and RK73G1HTTCM1002F are AEC-Q200 qualified, ROHS3 compliant, REACH unaffected, and classified as MSL 1 (unlimited moisture sensitivity). Both meet automotive industry standards for reliability and environmental compliance.
