Key Parameters

Substitute Part Grouping Explanation

Substitution between CF14JT2R40 and CFM14JT2R40 is valid based on the following criteria:

Identical Electrical Parameters:

• Resistance value: 2.4 Ohms
• Tolerance: ±5%
• Power rating: 0.25W (1/4W)
• Composition: Carbon Film
• Temperature coefficient: ±400ppm/°C
• Operating temperature range: -55°C to 155°C
• Termination count: 2

Identical Compliance & Safety:

• RoHS3 Compliant
• REACH Unaffected
• Flame Retardant Coating
• Safety features

Packaging Difference: The primary distinction is packaging format: CF14JT2R40 is supplied in Tape & Reel (TR) format, while CFM14JT2R40 is supplied in Cut Tape (CT) format. Both maintain identical axial package type and electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both CF14JT2R40 and CFM14JT2R40 are Active products with identical electrical specifications and full regulatory compliance. Selection between these parts is determined by packaging requirements and procurement logistics rather than electrical performance.

CF14JT2R40 is appropriate for high-volume automated assembly operations requiring Tape & Reel packaging format.

CFM14JT2R40 is appropriate for applications requiring Cut Tape packaging or when inventory availability favors this format. The CFM series variant maintains identical electrical performance and compliance certifications.

Physical dimension differences (0.091" Dia x 0.236" L versus 0.067" Dia x 0.130" L) reflect the different packaging presentations of the same component value and rating. Both are suitable for through-hole axial mounting in PCB applications within the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can CFM14JT2R40 replace CF14JT2R40 in circuit design?

A: Yes. Both parts have identical resistance value (2.4 Ohms), tolerance (±5%), power rating (0.25W), temperature coefficient (±400ppm/°C), and operating temperature range (-55°C to 155°C). Electrical performance is equivalent.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on tape segments cut to specified lengths, suitable for manual assembly or lower-volume operations. Both formats contain identical components.

Q: Are there physical size differences between these parts?

A: Yes. CF14JT2R40 measures 0.091" Dia x 0.236" L (2.30mm x 6.00mm), while CFM14JT2R40 measures 0.067" Dia x 0.130" L (1.70mm x 3.30mm). These dimensions reflect packaging format differences. Both are axial through-hole components suitable for standard PCB mounting.

Q: Do both parts meet the same compliance standards?

A: Yes. Both CF14JT2R40 and CFM14JT2R40 are ROHS3 Compliant, REACH Unaffected, and feature identical flame retardant coating and safety characteristics.

Q: Which part should I specify for new designs?

A: Selection depends on your assembly process. For automated high-volume production, specify CF14JT2R40 (Tape & Reel). For manual assembly or lower-volume applications, specify CFM14JT2R40 (Cut Tape). Both are Active products with equivalent electrical performance.
