Key Parameters

Substitute Part Grouping Explanation

Substitution of the PCF2CT631R680K is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (68 Ohms), tolerance (±10%), and power rating (2W) must be identical. Temperature coefficient range (-600 / -1500 ppm/°C) and operating temperature range (-40°C ~ 200°C) must match exactly.

Mechanical Parameters: Package type (Axial), physical dimensions (0.276" Dia x 0.748" L / 7.00mm x 19.00mm), and number of terminations (2) must be identical to ensure PCB compatibility and assembly process alignment.

Compliance & Certification: Automotive AEC-Q200 qualification, RoHS3 compliance, and ceramic composition with flame-proof, non-inductive, and pulse-withstanding characteristics must be maintained.

Packaging: Tape & Reel (TR) packaging format is standard for this product category.

The substitute part PCF2C680K meets all these criteria and is therefore a direct parametric equivalent.
