Substitute Part Grouping Explanation

Substitute parts for the CFF12JT680R are identified based on strict equivalence of the following critical parameters:

• Resistance value: 680 Ohms
• Tolerance: ±5%
• Power rating: 0.5W (1/2W)
• Composition: Carbon Film
• Package configuration: Axial through-hole
• Temperature coefficient: 0 / -400ppm/°C
• Operating temperature range: -55°C to 155°C
• Physical dimensions: 0.106" Dia x 0.335" L (2.70mm x 8.50mm)
• Termination count: 2
• Regulatory compliance: ROHS3 Compliant

The CF12JT680R qualifies as a parametric equivalent substitute. Both parts share identical electrical specifications, physical dimensions, and regulatory certifications. The primary distinction is packaging format: CFF12JT680R is supplied in Tape & Reel (TR) format, while CF12JT680R is supplied in Cut Tape (CT) format. Both are manufactured by Stackpole Electronics Inc and maintain the same series lineage and performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both CFF12JT680R and CF12JT680R are active production parts from Stackpole Electronics Inc with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on procurement and assembly requirements:

The CFF12JT680R in Tape & Reel format is suitable for high-volume automated assembly operations where tape-fed component handling is standard.

The CF12JT680R in Cut Tape format provides flexibility for lower-volume applications, manual assembly, or mixed-component procurement scenarios.

Both parts maintain identical electrical performance, thermal characteristics, and regulatory certifications, ensuring functional interchangeability within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can CF12JT680R be used as a direct replacement for CFF12JT680R?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance values, tolerances, power ratings, temperature coefficients, and operating ranges. The difference is packaging format only: Tape & Reel versus Cut Tape.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on tape segments, suitable for manual assembly or lower-volume applications.

Q: Are the physical dimensions identical between CFF12JT680R and CF12JT680R?

A: Yes. Both parts have identical axial package dimensions of 0.106" diameter by 0.335" length (2.70mm x 8.50mm), ensuring mechanical compatibility in PCB layouts and through-hole mounting.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both CFF12JT680R and CF12JT680R are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and safety standards.

Q: What determines substitutability for this resistor?

A: Substitutability is determined by matching resistance value (680 Ohms), tolerance (±5%), power rating (0.5W), composition (carbon film), package type (axial), temperature coefficient (0 / -400ppm/°C), operating temperature range (-55°C to 155°C), and physical dimensions (0.106" Dia x 0.335" L).
