Substitute Part Grouping Explanation

Substitute parts for the CF14JA2K00 are qualified based on the following criteria:

Direct Electrical Equivalence: Resistance value (2 kOhms), tolerance (±5%), and temperature coefficient (0 / -400ppm/°C) must match exactly.

Mechanical Compatibility: Package type (Axial) and termination count (2) must be identical to ensure physical fit in circuit board layouts.

Thermal Performance: Operating temperature range (-55°C ~ 155°C) must be maintained or exceeded.

Regulatory Compliance: RoHS3 compliance and REACH unaffected status must be preserved.

Composition: Carbon film composition ensures consistent electrical behavior across substitutes.

The following substitute parts meet these criteria:

PCF14JT2K00 (Direct substitute with packaging variation)
CFM14JT2K00 (Manufacturer recommended substitute)
CFM12JT2K00 (Upgrade substitute with increased power rating)

Engineering Selection Recommendations

PCF14JT2K00: This part provides direct electrical and thermal equivalence to the CF14JA2K00. The primary distinction is packaging format (Cut Tape versus Tape & Box) and the addition of radial bend capability. Both parts maintain identical electrical specifications and regulatory compliance. Selection depends on assembly process requirements and packaging availability.

CFM14JT2K00: This manufacturer-recommended substitute offers identical electrical specifications and power rating to the CF14JA2K00. The CFM series designation indicates a refined manufacturing process. Physical dimensions differ slightly (0.067" Dia x 0.130" L versus 0.091" Dia x 0.236" L), which may affect board layout compatibility. All regulatory certifications and thermal performance remain equivalent.

CFM12JT2K00: This part provides an upgrade path with doubled power rating (0.5W versus 0.25W) while maintaining all other electrical parameters. The increased power capacity allows operation in higher dissipation environments. Physical dimensions are slightly larger (0.091" Dia x 0.256" L). This substitution is appropriate when circuit design requires enhanced thermal margin or higher power handling capability.

All substitute parts are Active status, ROHS3 compliant, and REACH unaffected, ensuring regulatory compliance equivalent to the original CF14JA2K00.

Frequently Asked Questions (FAQ)

Q: Can PCF14JT2K00 replace CF14JA2K00 in all applications?

A: Yes, PCF14JT2K00 provides direct electrical equivalence with identical resistance, tolerance, power rating, and temperature coefficient. The packaging format differs (Cut Tape versus Tape & Box), but electrical performance is equivalent. Verify that your assembly process accommodates the packaging format.

Q: What is the difference between CFM14JT2K00 and CF14JA2K00?

A: Both parts share identical electrical specifications (2 kOhms ±5%, 0.25W, -55°C ~ 155°C). The CFM14JT2K00 represents a refined manufacturing series with slightly different physical dimensions. The smaller size (0.067" Dia x 0.130" L) may provide board layout advantages in space-constrained designs.

Q: When should CFM12JT2K00 be used instead of CF14JA2K00?

A: CFM12JT2K00 is appropriate when circuit power dissipation exceeds 0.25W or when design margin for thermal performance is required. The doubled power rating (0.5W) accommodates higher current applications while maintaining the same 2 kOhms resistance value. Verify that the slightly larger physical dimensions (0.091" Dia x 0.256" L) fit your board layout.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, CF14JA2K00, PCF14JT2K00, CFM14JT2K00, and CFM12JT2K00 are all ROHS3 compliant and REACH unaffected, ensuring regulatory equivalence across all substitutes.

Q: What determines substitution compatibility for these resistors?

A: Substitution compatibility is determined by matching resistance value (2 kOhms), tolerance (±5%), power rating (0.25W or higher), temperature coefficient (0 / -400ppm/°C), operating temperature range (-55°C ~ 155°C), and package type (Axial). All listed substitutes meet these criteria.
