Key Parameters

Substitute Part Grouping Explanation

Substitution of the RK73G1HTTC2402D is determined by strict equivalence across the following critical parameters:

• Resistance Value: 24 kOhms (exact match required)
• Tolerance: ±0.5% (exact match required)
• Power Rating: 0.05W / 1/20W (exact match required)
• Package: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±50ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Automotive Compliance: AEC-Q200 (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

Substitute parts must maintain identical electrical and mechanical specifications across all parameters listed above. No deviations in resistance value, tolerance, power rating, package dimensions, or automotive certification are permitted.

Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM2402D is the direct equivalent substitute for RK73G1HTTC2402D. Both components are manufactured by KOA Speer Electronics, Inc., and maintain identical electrical and mechanical specifications across all critical parameters.

The primary distinction between these parts is product status: RK73G1HTTC2402D is classified as "Not For New Designs," while RK73G1HTTCM2402D carries "Active" status. This indicates that RK73G1HTTCM2402D represents the current production equivalent and is the recommended selection for new designs and ongoing production requirements.

Both parts satisfy AEC-Q200 automotive qualification, ROHS3 compliance, and REACH unaffected status. Substitution between these parts presents no functional, electrical, mechanical, or compliance risk.

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM2402D be used as a direct replacement for RK73G1HTTC2402D?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including resistance value, tolerance, power rating, package dimensions, temperature coefficient, operating temperature range, and automotive certification. The substitute part carries active product status.

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

A: This designation indicates the part has been superseded by the manufacturer. While existing inventory remains available, new designs should transition to the active equivalent, RK73G1HTTCM2402D, to ensure long-term supply chain continuity.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the 0201 package (0603 Metric) with identical dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm). PCB layout and assembly processes require no modification.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both RK73G1HTTC2402D and RK73G1HTTCM2402D are AEC-Q200 qualified for automotive applications and maintain identical operating temperature range of -55°C ~ 155°C.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 1 - Unlimited). Regulatory and environmental compliance requirements are fully satisfied by either part.
