Key Parameters

Substitute Part Grouping Explanation

Substitution between CF12JT2R70 and CFM12JT2R70 is valid based on the following criteria:

Electrical Parameters (Identical):

• Resistance value: 2.7 Ohms
• Tolerance: ±5%
• Power rating: 0.5W (1/2W)
• Composition: Carbon Film
• Temperature coefficient: ±400ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Compatible):

• Package type: Axial (both parts)
• Number of terminations: 2 (both parts)
• Form factor: Through-hole axial configuration

Compliance & Certification (Identical):

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected
• ECCN: EAR99
• HTSUS: 8533.10.0065

The primary difference between these parts is packaging format: CF12JT2R70 is supplied in Tape & Reel (TR) format, while CFM12JT2R70 is supplied in Cut Tape (CT) format. Both parts are manufactured by Stackpole Electronics Inc within the same product series and maintain identical electrical and thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both CF12JT2R70 and CFM12JT2R70 are suitable for applications requiring 2.7 Ohm, 0.5W axial resistors with ±5% tolerance. Selection between these parts should be based on packaging requirements and procurement logistics:

CF12JT2R70 (Tape & Reel): Appropriate for high-volume automated assembly operations where tape and reel packaging supports pick-and-place equipment integration.

CFM12JT2R70 (Cut Tape): Appropriate for lower-volume applications, manual assembly, or situations where smaller packaging quantities are required.

Both parts maintain identical electrical performance, thermal characteristics, and regulatory compliance. The dimensional difference between the two parts (0.106" vs 0.091" diameter, 0.335" vs 0.256" length) reflects standard manufacturing variations within the carbon film resistor product line and does not affect functional compatibility in standard through-hole PCB applications.

Frequently Asked Questions (FAQ)

Q: Can CF12JT2R70 and CFM12JT2R70 be used interchangeably in circuit designs?

A: Yes. Both parts have identical electrical specifications (2.7 Ohms, ±5%, 0.5W), temperature coefficients, and operating temperature ranges. They are functionally equivalent for all circuit applications.

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 assembly lines. Cut Tape (CT) packaging supplies components on tape segments, suitable for manual assembly or lower-volume production. The component itself is identical.

Q: Are there dimensional compatibility concerns when substituting between these parts?

A: The CF12JT2R70 has a larger diameter (0.106" vs 0.091") and length (0.335" vs 0.256") compared to CFM12JT2R70. For standard through-hole PCB designs with typical lead spacing, both parts fit within normal component mounting tolerances. Verify PCB layout constraints if space is critical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both CF12JT2R70 and CFM12JT2R70 are ROHS3 compliant, REACH unaffected, and carry identical ECCN and HTSUS classifications.

Q: Which part should be selected for new designs?

A: Selection depends on manufacturing process. For automated assembly, use CF12JT2R70 (Tape & Reel). For manual assembly or prototype work, use CFM12JT2R70 (Cut Tape). Both are active products with equivalent long-term availability.
