Key Parameters

Substitute Part Grouping Explanation

Substitution of the RK73G1HTTC1500F is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (150 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 Specifications: Package format (0201 / 0603 Metric) and physical dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm) must match exactly to ensure PCB compatibility and assembly process compatibility.

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

Composition: Thick film construction must be maintained to preserve electrical performance characteristics.

Parts meeting all these criteria are classified as direct equivalents and may be substituted without circuit redesign or validation.
