Key Parameters

Substitute Part Grouping Explanation

Substitution of the PCF2CT631R151K is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (150 Ohms), tolerance (±10%), and power rating (2W) must be identical. Temperature coefficient range (-700 / -1800 ppm/°C) and operating temperature range (-40°C ~ 200°C) must match or exceed the original specification.

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.

Material & Composition: Ceramic composition is required. Non-inductive and pulse-withstanding characteristics must be maintained.

Compliance & Certification: Automotive AEC-Q200 qualification, RoHS3 compliance, and REACH unaffected status must be preserved. Flame-proof and safety features must be present.

The PCF2C151K meets all these criteria and is classified as a parametric equivalent substitute.
