Parameter Comparison

Engineering Selection Recommendations

CFM14JT2R00 (MFR Recommended Substitute): This part maintains identical electrical and mechanical specifications to the CF14JT2R00, including matching 0.25W power rating and 2 Ohm resistance. The CFM14JT2R00 is supplied in Cut Tape (CT) format versus the original Tape & Reel (TR) packaging. Both parts are Active status, ROHS3 compliant, and suitable for direct substitution in applications where packaging format does not impose constraints.

CFM12JT2R00 (Upgrade Substitute): This part provides identical electrical characteristics with an increased power rating of 0.5W (1/2W) compared to the 0.25W rating of the CF14JT2R00. The CFM12JT2R00 is suitable for applications requiring enhanced thermal dissipation capability or where circuit design margins benefit from higher power handling. All electrical parameters, temperature coefficients, and compliance certifications remain equivalent. This part is supplied in Cut Tape (CT) format.

Both substitutes maintain Active product status and full ROHS3 compliance, ensuring long-term availability and regulatory alignment with the original CF14JT2R00.

Frequently Asked Questions (FAQ)

Q: Can CFM14JT2R00 replace CF14JT2R00 in all applications? A: Yes. The CFM14JT2R00 provides identical electrical specifications (2 Ohms, ±5%, 0.25W) and operating characteristics. The difference is packaging format (Cut Tape versus Tape & Reel). Direct substitution is valid for circuit-level performance.

Q: What is the advantage of using CFM12JT2R00 over CF14JT2R00? A: The CFM12JT2R00 offers doubled power dissipation capability (0.5W versus 0.25W) while maintaining the same 2 Ohm resistance and ±5% tolerance. This upgrade is beneficial in high-current applications or where thermal margin is required.

Q: Are there physical size differences between these parts? A: Yes. The CF14JT2R00 measures 0.091" Dia x 0.236" L. The CFM14JT2R00 measures 0.067" Dia x 0.130" L. The CFM12JT2R00 measures 0.091" Dia x 0.256" L. Physical dimensions must be verified against PCB layout constraints before selection.

Q: Do all three parts meet the same compliance standards? A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Compliance certifications are equivalent across all substitutes.

Q: What packaging formats are available? A: CF14JT2R00 is supplied in Tape & Reel (TR) format. Both CFM14JT2R00 and CFM12JT2R00 are supplied in Cut Tape (CT) format. Packaging selection depends on assembly process requirements and component handling procedures.

Q: Can these parts be used interchangeably in automated assembly? A: Packaging format compatibility must be confirmed with assembly equipment specifications. Tape & Reel (TR) and Cut Tape (CT) formats require different feeder configurations. Consult assembly process documentation before substitution.
