Key Parameters

Substitute Part Grouping Explanation

Substitution of the RK73G1HTTC3000F is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (300 Ohms), tolerance (±1%), and power rating (0.05W) must be identical. Temperature coefficient (±50ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Parameters: Package type (0201 / 0603 Metric) and physical dimensions (0.024" L x 0.012" W, height 0.010" max) ensure PCB compatibility and assembly process compatibility.

Compliance & Quality: AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating are mandatory for applications requiring automotive-grade reliability.

Manufacturer Consistency: Parts from KOA Speer Electronics, Inc., within the RK73G series maintain design and performance consistency.

Substitute parts must match all parameters listed above. No deviations in electrical specifications, package dimensions, or automotive certifications are permitted.

Frequently Asked Questions (FAQ)

Q: Can RK73G1HTTCM3000F be used as a direct replacement for RK73G1HTTC3000F?

A: Yes. Both parts are electrically and mechanically identical. All parameters including resistance (300 Ohms), tolerance (±1%), power rating (0.05W), package (0201), temperature coefficient (±50ppm/°C), operating range (-55°C ~ 155°C), and automotive certifications (AEC-Q200) are equivalent. No circuit redesign or PCB layout modification is required.

Q: What is the significance of the product status difference?

A: The original part RK73G1HTTC3000F is marked "Not For New Designs," indicating it is in mature or end-of-life phase. The substitute RK73G1HTTCM3000F carries Active status, confirming ongoing manufacturing support and availability. For new production and long-term supply chain stability, RK73G1HTTCM3000F is the recommended selection.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and AEC-Q200 qualified. Moisture sensitivity level (MSL 1) and all regulatory classifications are identical.

Q: Will the 0201 package dimensions affect PCB assembly compatibility?

A: No. Both parts share identical physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm) with maximum seated height of 0.010" (0.26mm). Assembly equipment, solder reflow profiles, and PCB pad layouts require no adjustment.

Q: Are there any thermal performance differences?

A: No. Temperature coefficient (±50ppm/°C) and operating temperature range (-55°C ~ 155°C) are identical. Thermal behavior under identical load conditions will be equivalent.
