Substitute Part Grouping Explanation

Substitution of the RK73B1HTTC360G is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (36 Ohms), tolerance (±2%), and power rating (0.05W) must be identical. Temperature coefficient (±200ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

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

Composition & Construction: Thick film technology must be maintained to preserve electrical characteristics and reliability performance.

Compliance & Ratings: AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating are mandatory for equivalent substitution in automotive applications.

Manufacturer Consistency: Parts from KOA Speer Electronics, Inc. within the RK73B series maintain design and performance consistency.

The substitute part RK73B1HTTCM360G meets all these criteria while offering the advantage of Active product status, indicating ongoing manufacturer support and availability.
