    cross reference tps51285a

    I try to substitute the RT6575B with TPS51285A,
    it seems to work but it is slightly warmer, the board does not start due to other problems so but not sure if replacement is possible

    Re: cross reference tps51285a

    The TI cross reference website recommends the TPS51285 , (+ TPS51275) ,you still havwe to check the datasheet though for each parts LDO function https://bomcross.ti.com/en/search?searchTerm=RT6575

    TPS51285A VREG3 ,TPS51285B VREG3 and VREG5 always on

    The RT6575B has VREG3 and VREG5 always on,so the correct substitute part is the TPS51285B not A

      Thermistor specs and cross reference
      by connorcc2005
      Hi,

      I'm getting some conflicting information and thought I'd toss it out to all of you for input.
      What I have is a TTC-104 thermistor. This is part of a temp sense circuit that will drive a small 12v fan to cool components mounted to SMPS heat sink.
      The physical diameter of the piece is 5.1mm measured with a caliper.
      Other than what you see in the pic, there is no other writing on the part.

      My research of the TTC-104 says it should read 100 ohms at 25C. Out of circuit measurements have it at approximately 100k. It does change as the temp changes....

      Voltage regulator cross-reference
      by raregtp
      Hey all....hoping someone can help me with this. I have a couple voltage regulators I'm trying to cross but not having much luck.

      The first is:

      A1
      AS1117L-18
      B0640 25

      The second is:

      A1
      AS1117L-33
      B0640 28

      I know the AS stands for Alpha Semiconductor, and I think I've found a datasheet for the AS1117L-33, just can't find anything for the -18. Ultimately I'm looking to cross these over to parts that I can get now, as all I'm finding similar are AZ1117 regulators.

      If anyone can assist...

      Reference Nvidia GTX 980 ti - looking for a new shroud
      by speaktorob
      So a while back, to deal with the fan noise of the old blower style shrouds on the reference cards, I chucked it and installed the monster that is a Raijintek MORPHEUS 8069, with a couple Noctuas on it. Did the job but quite unwieldy tbh.

      Anyone know which boards would have a compatible shroud for it? I know the EVGA used the reference board but wondering if any other manufacturers did. I want to put something sensible back on it, but I'm having a hard time getting hold of even a faulty reference board for a reasonable price.

      Chip reference DA0G7BMB6D0 rév D HP Pavilion - 15-cs0006nf
      by Rhork
      Hello,

      I would like to know the reference of a QFN-20 because the reference marked on the chip does not give anything...
      PC Reference : HP Pavilion - 15-cs0006nf
      Motherboard : DA0G7BMB6D0 rev D
      Reference marked on the chip: AWVAIL
      Type : QFN-20

      I didn't find a boardview or repair schematics

      Thanks in advance...

      Help with cross reference FET
      by merkin
      Hi,
      I have a FET that is shorted and I need help finding a replacement preferably from Digikey.

      The marking on the FET is AP30P10GH.

      Thanks in advance.
