Substitute Part Grouping Explanation

Substitution eligibility for the RK73B1HTTC132G is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (1.3 kOhms), 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 Specifications: Package type (0201), physical dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm), and seated height (0.010" / 0.26mm maximum) ensure PCB compatibility and assembly process alignment.

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

Composition & Construction: Thick film technology and two-termination configuration must be maintained.

Parts meeting all these criteria are classified as direct substitutes. The RK73B1HTTCM132G satisfies all substitution parameters while maintaining active product status.
