Substitute Part Grouping Explanation

Substitution eligibility for the PCF2CT631R150K is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 15 Ohms
• Tolerance: ±10%
• Power rating: 2W
• Temperature coefficient: -600/-1500ppm/°C
• Operating temperature range: -40°C ~ 200°C

Mechanical Parameters:

• Package type: Axial
• Physical dimensions: 0.276" Dia x 0.748" L (7.00mm x 19.00mm)
• Number of terminations: 2

Compliance & Certification:

• Automotive AEC-Q200 qualification
• ROHS3 compliance
• Ceramic composition with flame-proof and non-inductive construction

The PCF2CT631R150K and its substitute differ only in packaging configuration (cut tape versus tape & reel), which does not affect electrical performance or mechanical compatibility in circuit applications.

Engineering Selection Recommendations

The PCF2C150K (Tape & Reel packaging) is a direct electrical and mechanical equivalent to the PCF2CT631R150K (Cut Tape packaging). Both components maintain identical electrical specifications, physical dimensions, and automotive compliance certifications.

Selection Criteria:

The choice between these parts is determined solely by packaging and supply requirements:

• PCF2CT631R150K (Cut Tape): Suitable for lower-volume applications, prototype development, and manual assembly processes where individual component handling is required.

• PCF2C150K (Tape & Reel): Suitable for high-volume production runs and automated assembly processes where continuous tape feeding is utilized.

Both parts are ROHS3 compliant, AEC-Q200 qualified, and maintain identical electrical performance across the full operating temperature range of -40°C to 200°C. Component selection should be based on production volume, assembly methodology, and supply chain logistics rather than electrical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can PCF2C150K be used as a direct replacement for PCF2CT631R150K in circuit designs?

A: Yes. The PCF2C150K is electrically and mechanically equivalent to the PCF2CT631R150K.
