Key Parameters

Substitute Part Grouping Explanation

The CFM14JT3R30 qualifies as a direct substitute based on the following criteria:

Electrical Parameters Match:

• Resistance value: 3.3 Ohms (identical)
• Tolerance: ±5% (identical)
• Power rating: 0.25W, 1/4W (identical)
• Temperature coefficient: ±400ppm/°C (identical)
• Operating temperature range: -55°C to 155°C (identical)
• Composition: Carbon Film (identical)

Mechanical Compatibility:

• Package type: Axial (identical)
• Number of terminations: 2 (identical)
• Supplier device package: Axial (identical)

Compliance & Certification:

• RoHS3 Compliant (identical)
• REACH Unaffected (identical)
• ECCN: EAR99 (identical)
• HTSUS: 8533.10.0065 (identical)

Packaging Difference: The primary distinction is packaging format: CF14JT3R30 is supplied in Tape & Reel (TR) format, while CFM14JT3R30 is supplied in Cut Tape (CT) format. This difference affects procurement and assembly processes but does not alter electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both CF14JT3R30 and CFM14JT3R30 maintain Active product status and identical RoHS3 and REACH compliance certifications. Selection between these parts should be based on packaging requirements and inventory availability. The CFM14JT3R30 offers significantly higher inventory levels (19901 units versus 782 units), making it suitable for high-volume production runs. The CF14JT3R30 in Tape & Reel format is appropriate for automated assembly processes requiring continuous reel feeding. Both parts satisfy identical electrical and thermal specifications for circuit applications within the stated operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can CFM14JT3R30 be used as a direct replacement for CF14JT3R30 in circuit design?

A: Yes. Both parts have identical electrical specifications: 3.3 Ohms resistance, ±5% tolerance, 0.25W power rating, ±400ppm/°C temperature coefficient, and -55°C to 155°C operating range. Electrical performance is equivalent.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on continuous reels for automated pick-and-place assembly. Cut Tape packaging provides components on tape segments for manual or semi-automated handling. Both formats contain identical components; the difference is in procurement and assembly methodology.

Q: Are there physical size differences between these parts?

A: Yes. CF14JT3R30 measures 0.091" diameter x 0.236" length (2.30mm x 6.00mm). CFM14JT3R30 measures 0.067" diameter x 0.130" length (1.70mm x 3.30mm). Despite dimensional differences, both are axial through-hole resistors with identical electrical characteristics and two terminations.

Q: Do both parts meet the same compliance standards?

A: Yes. Both CF14JT3R30 and CFM14JT3R30 are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99 with HTSUS code 8533.10.0065.

Q: Which part should be selected for high-volume production?

A: CFM14JT3R30 is recommended for high-volume applications due to significantly higher inventory availability (19901 units in stock). CF14JT3R30 in Tape & Reel format is suitable when automated assembly equipment requires continuous reel feeding.
