Key Parameters

Substitute Part Grouping Explanation

The CF12JT150R qualifies as a parametric equivalent to the CFF12JT150R based on the following critical substitution criteria:

Electrical Parameters (Identical):

• Resistance: 150 Ohms
• Tolerance: ±5%
• Power Rating: 0.5W (1/2W)
• Temperature Coefficient: 0 / -400ppm/°C
• Operating Temperature Range: -55°C to 155°C

Mechanical Parameters (Identical):

• Package Type: Axial
• Physical Dimensions: 0.106" Dia × 0.335" L (2.70mm × 8.50mm)
• Number of Terminations: 2

Composition & Safety (Equivalent):

• Composition: Carbon Film
• Manufacturer: Stackpole Electronics Inc (same manufacturer)
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Packaging Difference: The primary distinction is packaging format: CFF12JT150R is supplied in Tape & Reel (TR) format, while CF12JT150R is supplied in Cut Tape (CT) format. Both formats contain identical components with no electrical or mechanical differences.

Parameter Comparison

Engineering Selection Recommendations

Both CFF12JT150R and CF12JT150R are active production parts from Stackpole Electronics Inc with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on packaging requirements and supply availability:

CFF12JT150R (Tape & Reel): Suitable for high-volume automated assembly operations where tape-and-reel packaging provides efficient component feeding through pick-and-place equipment.

CF12JT150R (Cut Tape): Suitable for lower-volume applications, manual assembly, or situations where individual component access is preferred. Cut tape format provides greater flexibility for mixed-component orders.

Both parts deliver identical electrical performance and mechanical compatibility. The choice between them is determined by manufacturing process requirements and inventory management strategy, not by technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can CF12JT150R be used as a direct replacement for CFF12JT150R in circuit design?

A: Yes. Both parts are electrically and mechanically identical. The CF12JT150R will function identically in any application designed for the CFF12JT150R. The only difference is the packaging format supplied by the manufacturer.

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

A: Tape & Reel packaging supplies components on a continuous reel suitable for automated pick-and-place assembly. Cut Tape packaging supplies the same components on tape segments, typically used for lower-volume orders or manual assembly. The resistor components themselves are identical.

Q: Are there any compliance or certification differences between these parts?

A: No. Both CFF12JT150R and CF12JT150R carry identical RoHS3 compliance and REACH unaffected status. Safety certifications and regulatory compliance are equivalent.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the assembly process can accommodate the packaging format. Automated assembly lines typically require Tape & Reel format, while manual assembly or lower-volume production may prefer Cut Tape format. The actual component performance is identical.

Q: What is the operating temperature range for both parts?

A: Both CFF12JT150R and CF12JT150R operate across -55°C to 155°C, with a temperature coefficient of 0 / -400ppm/°C. This range is suitable for industrial and commercial applications.

Q: Are inventory levels a consideration when selecting between these parts?

A: Yes. CFF12JT150R has 1126 units in stock, while CF12JT150R has 7125 units in stock. If supply continuity is a concern, CF12JT150R offers higher current availability.
