Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PCF14JT120R are qualified based on the following electrical and mechanical parameters:

Electrical equivalence is established through matching resistance value (120 Ohms), tolerance (±5%), power rating (0.25W), composition (carbon film), temperature coefficient (0 / -400ppm/°C), and operating temperature range (-55°C to 155°C). All substitute parts maintain identical electrical specifications and compliance certifications (ROHS3, REACH unaffected).

Mechanical compatibility is determined by package type (axial configuration) and termination count (2 terminations). The primary distinction among qualified substitutes is packaging format: the main part PCF14JT120R is supplied in Tape & Reel (TR) format with axial/radial bend capability, while direct substitutes CF14JT120R and CFM14JT120R are supplied in Cut Tape (CT) format with standard axial configuration. Physical dimensions vary between the standard CF series (0.091" Dia x 0.236" L) and the miniature CFM series (0.067" Dia x 0.130" L), reflecting different form factors within the same electrical specification.

Parameter Comparison

Engineering Selection Recommendations

All three parts—PCF14JT120R, CF14JT120R, and CFM14JT120R—are electrically and functionally equivalent for applications requiring a 120 Ohms ±5% 0.25W carbon film resistor. Selection among these parts is determined by packaging and form factor requirements rather than electrical performance.

PCF14JT120R in Tape & Reel format is suitable for high-volume automated assembly processes. CF14JT120R in Cut Tape format provides the same standard form factor (0.091" Dia x 0.236" L) and is appropriate for lower-volume or mixed-component applications. CFM14JT120R, the manufacturer-recommended alternative, offers a miniature form factor (0.067" Dia x 0.130" L) in Cut Tape packaging, enabling space-constrained designs while maintaining identical electrical specifications.

All parts maintain active production status and full compliance with ROHS3 and REACH requirements, ensuring long-term availability and regulatory conformance for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can CF14JT120R be used as a direct replacement for PCF14JT120R?

A: Yes. Both parts are electrically identical with matching resistance (120 Ohms), tolerance (±5%), power rating (0.25W), and operating temperature range (-55°C to 155°C). The primary difference is packaging format: PCF14JT120R is supplied in Tape & Reel while CF14JT120R is supplied in Cut Tape. Physical dimensions are identical (0.091" Dia x 0.236" L). Selection depends on assembly process requirements.

Q: What is the difference between CF14JT120R and CFM14JT120R?

A: Both parts are electrically equivalent with identical resistance, tolerance, power rating, and temperature specifications. The CFM14JT120R is a miniature variant with reduced physical dimensions (0.067" Dia x 0.130" L compared to 0.091" Dia x 0.236" L). Both are supplied in Cut Tape format. CFM14JT120R is recommended by the manufacturer and is suitable for applications requiring compact component placement.

Q: Are all three parts ROHS3 compliant?

A: Yes. PCF14JT120R, CF14JT120R, and CFM14JT120R are all ROHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial and commercial applications.

Q: Which part should I select for a new design?

A: Selection is based on packaging and form factor needs. For automated high-volume assembly, use PCF14JT120R (Tape & Reel). For manual or mixed-component assembly with standard form factor, use CF14JT120R (Cut Tape). For space-constrained designs, use CFM14JT120R (Cut Tape, miniature form factor). All three are electrically equivalent.

Q: Can the miniature CFM14JT120R be used in place of the standard CF14JT120R?

A: Yes, provided the PCB layout and mechanical clearances accommodate the smaller dimensions (0.067" Dia x 0.130" L). Electrical performance is identical. Verify physical fit before design implementation.
