Frequently asked questions
What is the difference between the 8535AGI-31LFT and the 8535AG-31LF?
The primary difference is the packaging and ordering suffix. The 8535AGI-31LFT is supplied in tape and reel packaging, while the 8535AG-31LF is supplied in tube packaging. Both devices are functionally identical clock generators from the same manufacturer and share the same electrical specifications.
Are the 8535AGI-31LFT and 8535AG-31LF electrically interchangeable?
Yes. Both part numbers refer to the same base device, the 8535-31, which is a clock generator IC. The electrical parameters, pinout, and functional behavior are identical. The only difference is the shipping packaging format indicated by the suffix.
What does the "T" suffix indicate on the 8535AGI-31LFT?
The "T" suffix indicates tape and reel packaging. This is the standard packaging format for automated pick-and-place assembly lines. The 8535AG-31LF without the "T" suffix is supplied in tubes.
What is the function of the 8535AGI-31LFT and 8535AG-31LF?
Both devices are clock generator ICs designed to produce a low-jitter output clock signal from a reference input. They are commonly used in networking, telecommunications, and data acquisition systems requiring precise timing.
Can the 8535AGI-31LFT and 8535AG-31LF be used in the same PCB footprint?
Yes. Since both part numbers refer to the same base device in the same package type, the PCB footprint and pin assignments are identical. Either part can be placed on the same land pattern.
Which part number should be ordered for production runs?
For automated production assembly, the 8535AGI-31LFT in tape and reel is typically preferred. For prototyping or manual assembly, the 8535AG-31LF in tubes may be more convenient. Both contain the same device.
Do the 8535AGI-31LFT and 8535AG-31LF have the same operating temperature range?
Yes. Both part numbers share the same operating temperature range as specified in the manufacturer datasheet for the 8535-31 device. The packaging suffix does not affect the temperature grade.
