Alternative to PNA4601 Ir Receiver

This probably falls under the category of "Things everyone already knew", but just in case...

I've been sourcing products for Propellerpowered, and wanted to stock an IR Receiver. The PNA4601 that Parallax sells is getting hard to find outside of Parallax and is expensive.

I ordered a few TSOP4838's for testing and discovered that they are both pin compatible with the PNA4601, as well as able to be powered from voltages from 2.7v to 5.5v. I took some time to create an example program which uses the 4838 with the Parallax remote (in Sony mode). (Can be found on this page)

Mission accomplished, but probably much ado for a minor product that every probably already knew was compatible.

Ping if this was news. :):)

    Your link "this page" goes to the data sheet for the device not your example of using it.

    FYI I have used the IR receiver from Paallax, Adafruit, and off the shelf at Radio Shack and all worked the same.
    Not much of a test as I am only using two Sony Remotes with them. The Radio Shack one came with some metal
    shielding but I noticed they no longer had that one at my local store.
    I noticed in testing my FM Radio Project that the kind shown in my pictures could even be viewed as to sensitive, I
    could point the remote anywhere even up at the celing while standing across the room and the radio would respond
    as expected.

    Thanks Tom!

    Fixed the "Demonstration Object" link.

    Just be careful to get the version with the wider voltage. There is a version for 4.5-5.5V. It's in a different package (I believe), but is only differentiated by a suffix.

    A few years ago I was working on an IR curtain design. I was in contact with Vishay on a number of design questions. Great people to work with. These devices have built in AGC. They also make some versions with fixed AGC for real high sensitivity.

    I use the Vishay BPW41N photo-diode. They are available everywhere.
