Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73G1HTTC2402F is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (24 kOhms), tolerance (±1%), power rating (0.05W), and temperature coefficient (±50ppm/°C) must be identical.

Mechanical Parameters: Package designation (0201 / 0603 Metric), 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 & Ratings: AEC-Q200 automotive qualification, RoHS3 compliance, and MSL 1 rating must be maintained.

Composition: Thick film construction is required.

The substitute part RK73G1HTTCM2402F meets all these criteria and represents the active product line equivalent.

Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM2402F is the direct equivalent substitute for the RK73G1HTTC2402F. Both parts are manufactured by KOA Speer Electronics, Inc., within the RK73G series, and share identical electrical specifications, mechanical dimensions, and automotive compliance certifications.

The primary distinction is product status: RK73G1HTTC2402F is designated "Not For New Designs," while RK73G1HTTCM2402F maintains "Active" status. This status change reflects the manufacturer's product line evolution and indicates that RK73G1HTTCM2402F represents the current supported alternative.

For applications currently using RK73G1HTTC2402F, transition to RK73G1HTTCM2402F is supported without circuit redesign, as all functional and mechanical parameters remain constant. Both parts satisfy AEC-Q200 automotive requirements, ROHS3 compliance, and unlimited moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM2402F be used as a direct replacement for RK73G1HTTC2402F in existing designs?

A: Yes. Both parts are electrically and mechanically identical. All critical parameters—resistance (24 kOhms), tolerance (±1%), power rating (0.05W), package (0201), temperature range (-55°C ~ 155°C), and AEC-Q200 rating—are equivalent. No circuit modifications are required.

Q: What is the significance of the "Not For New Designs" status on RK73G1HTTC2402F?

A: This designation indicates the part has been superseded in the manufacturer's active product portfolio. While existing inventory remains available, KOA Speer Electronics recommends RK73G1HTTCM2402F for new design implementations. Both parts maintain identical specifications and compliance certifications.

Q: Are the physical dimensions identical between these two parts?

A: Yes. Both parts conform to 0201 package (0603 Metric) with dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm). They are footprint-compatible on PCB layouts.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both RK73G1HTTC2402F and RK73G1HTTCM2402F carry AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the temperature coefficient specification for these resistors?

A: Both parts specify ±50ppm/°C temperature coefficient across the -55°C to 155°C operating range, ensuring stable resistance performance in automotive thermal environments.
