Engineering Selection Recommendations

CF14JT2K20 (Direct Substitute)

The CF14JT2K20 is electrically and mechanically equivalent to the PCF14JT2K20. Both parts share identical electrical specifications, temperature characteristics, and compliance certifications. The primary difference is packaging format: CF14JT2K20 is supplied in Cut Tape (CT) format versus Tape & Reel (TR) for the PCF14JT2K20. Physical dimensions are identical. This part is suitable for direct substitution in applications where Cut Tape packaging is acceptable. Inventory availability is significantly higher (535,722 pcs vs. 723 pcs).

CFM14JT2K20 (Manufacturer-Recommended Substitute)

The CFM14JT2K20 is electrically equivalent to the PCF14JT2K20 with identical resistance, tolerance, power rating, temperature coefficient, and operating temperature range. This part belongs to the CFM series and features reduced physical dimensions (0.067" Dia x 0.130" L vs. 0.091" Dia x 0.236" L). Both parts maintain ROHS3 compliance and REACH Unaffected status. The CFM14JT2K20 is suitable for applications where space constraints permit use of a smaller form factor resistor. Inventory availability is moderate (14,361 pcs).

All substitute parts maintain Active product status and are manufactured by Stackpole Electronics Inc, ensuring consistent quality and long-term availability.

Frequently Asked Questions (FAQ)

Q: Can CF14JT2K20 be used as a direct replacement for PCF14JT2K20?

A: Yes. Both parts have identical electrical specifications (2.2 kOhms ±5%, 0.25W, carbon film composition) and operating characteristics (-55°C to 155°C). The difference is packaging format only: CF14JT2K20 is supplied in Cut Tape while PCF14JT2K20 is supplied in Tape & Reel. Electrical and mechanical performance are equivalent.

Q: What is the difference between PCF14JT2K20 and CFM14JT2K20?

A: Both parts are electrically identical (2.2 kOhms ±5%, 0.25W, carbon film). The CFM14JT2K20 has a smaller physical size (0.067" Dia x 0.130" L) compared to the PCF14JT2K20 (0.091" Dia x 0.236" L). The CFM14JT2K20 is suitable for space-constrained applications while maintaining all electrical and compliance specifications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. PCF14JT2K20, CF14JT2K20, and CFM14JT2K20 are all ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) and Cut Tape (CT) packaging formats are logistics and handling variations only. Electrical specifications, performance characteristics, and reliability are identical between parts with different packaging formats.

Q: Can CFM14JT2K20 be used in PCB layouts designed for PCF14JT2K20?

A: CFM14JT2K20 has different physical dimensions and may require PCB layout modifications. Verify that the smaller form factor (0.067" Dia x 0.130" L) is compatible with existing pad spacing and component placement before substitution.

Q: What is the temperature coefficient specification for these resistors?

A: All three parts have a temperature coefficient of 0 / -400ppm/°C and operate across the range -55°C to 155°C, ensuring stable resistance values across industrial and commercial temperature environments.
