Substitute Part Grouping Explanation

Substitute parts for the PCF2CT631R271K are identified based on strict equivalence of the following critical parameters:

• Resistance Value: 270 Ohms
• Tolerance: ±10%
• Power Rating: 2W
• Composition: Ceramic
• Package Configuration: Axial through-hole
• Physical Dimensions: 0.276" Dia x 0.748" L (7.00mm x 19.00mm)
• Operating Temperature Range: -40°C ~ 200°C
• Temperature Coefficient: -700 / -1800 ppm/°C
• Automotive Certification: AEC-Q200
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. The PCF2C271K meets all specified criteria and is therefore a valid substitute.
