Key Parameters

Substitute Part Grouping Explanation

Substitution of the RK73G1HTTC2000D is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (200 Ohms), tolerance (±0.5%), power rating (0.05W), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C ~ 155°C) must be identical.

Mechanical Parameters: Package type (0201/0603 metric), physical dimensions (0.024" L x 0.012" W, 0.26mm max height), and number of terminations (2) must match exactly.

Compliance & Quality: Automotive AEC-Q200 qualification, ROHS3 compliance, and MSL 1 rating are mandatory for substitution eligibility.

Series Compatibility: Both the main part and substitute parts belong to the KOA Speer Electronics RK73G series, confirming design and manufacturing consistency.

The substitute part RK73G1HTTCM2000D meets all these criteria and differs only in product status (Active vs. Not For New Designs) and packaging designation, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The RK73G1HTTCM2000D is the direct substitute for RK73G1HTTC2000D based on complete electrical and mechanical equivalence. The primary distinction is product lifecycle status: the original part is designated "Not For New Designs," while the substitute maintains Active status within the same RK73G series from KOA Speer Electronics.

Both parts carry identical AEC-Q200 automotive qualification, ROHS3 compliance, and unlimited moisture sensitivity rating (MSL 1), confirming suitability for automotive applications without additional qualification requirements. The substitute part is available in higher inventory (968 pcs vs. 943 pcs), supporting production continuity.

Selection of RK73G1HTTCM2000D is appropriate for applications currently using RK73G1HTTC2000D, particularly for new production runs and long-term supply chain planning.

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM2000D be used as a direct replacement for RK73G1HTTC2000D in existing designs?

A: Yes. Both parts are electrically and mechanically identical with matching resistance (200 Ohms ±0.5%), power rating (0.05W), package (0201), temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. No circuit redesign or re-qualification is required.

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

A: This designation indicates the RK73G1HTTC2000D is in end-of-life phase. The substitute RK73G1HTTCM2000D maintains Active status, ensuring long-term availability and supply chain stability for new production.

Q: Are there any differences in package or physical dimensions between these parts?

A: No. Both parts use identical 0201 (0603 metric) packaging with dimensions of 0.024" L x 0.012" W and maximum seated height of 0.010" (0.26mm). They are mechanically interchangeable on PCBs.

Q: Do both parts meet the same automotive and compliance standards?

A: Yes. Both parts are AEC-Q200 qualified, ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. Compliance requirements are identical.

Q: Is there a difference in temperature coefficient between these parts?

A: No. Both parts have identical temperature coefficient of ±50ppm/°C and operate across the same temperature range of -55°C to 155°C.

Q: Can these parts be mixed in the same production batch?

A: Yes. Electrical and mechanical specifications are identical, allowing interchangeable use within the same assembly or production run without performance impact.
