Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RK73B1HTTC113G is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (11 kOhms), tolerance (±2%), power rating (0.05W), temperature coefficient (±200ppm/°C), and operating temperature range (-55°C ~ 155°C) must be identical.

Mechanical Parameters: Package format (0201 / 0603 Metric), physical dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm), and number of terminations (2) must match exactly.

Compliance & Composition: Thick film composition, AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating are mandatory for substitution in automotive applications.

Manufacturer Consistency: Parts from KOA Speer Electronics, Inc. within the RK73B series meeting all above criteria are eligible substitutes.
