Key Parameters

Substitute Part Grouping Explanation

Substitution between CF12JT3R90 and CFM12JT3R90 is valid based on the following criteria:

Identical Electrical Parameters:

• Resistance value: 3.9 Ohms
• Tolerance: ±5%
• Power rating: 0.5W (1/2W)
• Composition: Carbon Film
• Temperature coefficient: ±400ppm/°C
• Operating temperature range: -55°C to 155°C
• Features: Flame retardant coating and safety characteristics

Allowed Variation:

• Packaging format: Tape & Reel (TR) versus Cut Tape (CT)
• Physical dimensions: Minor size differences (0.106" Dia x 0.335" L versus 0.091" Dia x 0.256" L)
• Series designation: CF versus CFM

Both parts maintain identical electrical performance and compliance certifications, making them functionally interchangeable in circuit applications. The packaging difference reflects distribution and handling methods rather than component performance.

Parameter Comparison

Engineering Selection Recommendations

Both CF12JT3R90 and CFM12JT3R90 are active production parts with identical ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on packaging requirements and inventory availability. The Tape & Reel format (CF12JT3R90) is suitable for automated assembly processes, while the Cut Tape format (CFM12JT3R90) accommodates manual assembly or lower-volume applications. Both parts satisfy identical electrical specifications and regulatory requirements for circuit implementation.

Frequently Asked Questions (FAQ)

Q: Can CFM12JT3R90 replace CF12JT3R90 in production assemblies?

A: Yes. Both parts have identical electrical specifications, power ratings, tolerance, and operating temperature ranges. The difference is packaging format only. Verify that your assembly process can accommodate Cut Tape (CT) format if switching from Tape & Reel (TR).

Q: Are there physical dimension differences between these parts?

A: Yes. CF12JT3R90 measures 0.106" Dia x 0.335" L (2.70mm x 8.50mm), while CFM12JT3R90 measures 0.091" Dia x 0.256" L (2.30mm x 6.50mm). Both are axial package types. Confirm PCB layout and component spacing accommodate the smaller CFM12JT3R90 dimensions if substituting.

Q: Do both parts meet the same compliance standards?

A: Yes. Both CF12JT3R90 and CFM12JT3R90 are ROHS3 compliant and REACH unaffected, with identical ECCN (EAR99) and HTSUS classifications.

Q: What is the temperature coefficient difference between these parts?

A: There is no difference. Both parts have a temperature coefficient of ±400ppm/°C across the -55°C to 155°C operating range.

Q: Which part should I select for high-volume automated assembly?

A: CF12JT3R90 in Tape & Reel format is optimized for automated pick-and-place assembly. CFM12JT3R90 in Cut Tape format is suitable for manual assembly or lower-volume production runs.
