Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CF14JT2R70 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 2.7 Ohms
• Tolerance: ±5%
• Composition: Carbon Film
• Temperature Coefficient: ±400ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Package Type: Axial
• RoHS Compliance: ROHS3 Compliant

Variable Parameters Allowing Substitution:

• Power Rating: May increase from 0.25W to higher ratings
• Packaging Format: May change from Tape & Reel to Cut Tape
• Physical Dimensions: May vary within axial package constraints
• Series Designation: May differ (CF vs CFM series)

The CF14JT2R70 can be substituted with parts that maintain identical electrical specifications while potentially offering increased power dissipation or alternative packaging configurations.

Parameter Comparison

Engineering Selection Recommendations

CFM12JT2R70 (Upgrade Option): This substitute provides identical electrical characteristics to the CF14JT2R70 with increased power dissipation capacity at 0.5W. Selection of this part is appropriate when circuit design requires higher thermal margin or when operating conditions demand greater power handling. The CFM12JT2R70 maintains full ROHS3 compliance and REACH unaffected status. Packaging changes from Tape & Reel to Cut Tape format. Physical dimensions increase to 0.091" Dia x 0.256" L (2.30mm x 6.50mm), which may require board layout verification.

CFM14JT2R70 (Manufacturer Recommended): This substitute maintains identical power rating (0.25W) and electrical specifications as the CF14JT2R70. The CFM14JT2R70 represents the manufacturer-recommended equivalent within the CFM series. Packaging format changes from Tape & Reel to Cut Tape. Physical dimensions reduce to 0.067" Dia x 0.130" L (1.70mm x 3.30mm), offering a more compact footprint. Full ROHS3 compliance and REACH unaffected status are maintained.

Both substitutes are active production parts with established inventory availability and maintain all regulatory compliance certifications of the original part.

Frequently Asked Questions (FAQ)

Q: Can CFM12JT2R70 be used as a direct replacement for CF14JT2R70? A: Yes. The CFM12JT2R70 maintains identical resistance (2.7 Ohms), tolerance (±5%), temperature coefficient (±400ppm/°C), and operating temperature range (-55°C to 155°C). The increased power rating (0.5W vs 0.25W) provides additional thermal margin. Physical dimensions and packaging format differ; board layout compatibility must be verified.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for automated assembly processes. Cut Tape packaging provides components on tape segments cut to specified lengths, suitable for manual assembly or smaller production runs. Both formats contain identical components; selection depends on assembly process requirements.

Q: Is CFM14JT2R70 electrically identical to CF14JT2R70? A: Yes. Both parts share identical electrical specifications: 2.7 Ohms resistance, ±5% tolerance, 0.25W power rating, ±400ppm/°C temperature coefficient, and -55°C to 155°C operating range. The CFM14JT2R70 offers a more compact physical footprint (0.067" Dia x 0.130" L vs 0.091" Dia x 0.236" L) and different packaging format.

Q: Do all substitute parts maintain RoHS and REACH compliance? A: Yes. CF14JT2R70, CFM12JT2R70, and CFM14JT2R70 are all ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: When should CFM12JT2R70 be selected over CFM14JT2R70? A: CFM12JT2R70 should be selected when circuit design requires power dissipation greater than 0.25W or when thermal margin is a design consideration. CFM14JT2R70 should be selected when the 0.25W power rating is sufficient and compact dimensions are preferred.
