Substitute Part Grouping Explanation

Substitution eligibility for the PCF2CT631R101K is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (100 Ohms), tolerance (±10%), and power rating (2W) must be identical. These parameters define the functional performance in the circuit.

Physical Parameters: Package type (Axial), physical dimensions (0.276" Dia x 0.748" L), and number of terminations (2) must match to ensure mechanical compatibility with printed circuit board layouts and assembly equipment.

Environmental & Compliance Parameters: Operating temperature range (-40°C ~ 200°C), temperature coefficient (-700 / -1800 ppm/°C), automotive qualification (AEC-Q200), and RoHS3 compliance status must be maintained to preserve reliability and regulatory conformance in automotive applications.

Material Composition: Ceramic composition with flame-proof, non-inductive, and pulse-withstanding characteristics must be preserved.

The substitute part PCF2C101K meets all these criteria and is classified as a parametric equivalent.
