Hello,
I need to replace the TSOP7000 IR receiver (at 455khz) that is now obsolete from my electronic device.
Do you know any equivalent component or elementary opto electronic assembly that can replace it?

Thank you

You can use a generic photodiode or phototransistor (e.g., BPW34) paired with an external signal-processing circuit to filter and amplify the 455 kHz signal.

Thank you for your response.
Yes I know. I am expecting more specific answers. Any schematics or example?

As suggested by aliarifat794, do you know a circuit/schematics that filters and amplify the signal from a generic photodiode as if it was almost a TSOP7000 output?

High bitrate IR receiver (TSOP7000 replacement)

After a many days of research I turned to stack overflow once again to help me. I'm looking for High speed IR receiver circuit for laser-tag weapon. Requirements are High noise cancelation, high

Required circuit function (IR sensitivity, filter bandwidth, AGC time constant, demodulator output filter ) can be derived from TSOP7000 datasheet, not sure if your application exhausts all parameters. In any case it's a complex circuit design. An OP implementation would need a quad OP, 10 to 20 R and C parts, some discrete diodes and transistors plus respective design skill.

Vishay seems to have some devices

Many devices in 20 to 60 kHz range. The thread is specifically asking about 455 kHz IR receivers. Vishay had TSOP7000, but it's obsoleted. Apparently there's no sufficient demand for 455 kHz receivers to maintain the production.

Apparently, TSOP7000 is still available at resellers and Ebay. Probably the cheapest option, presumed the parts are no fake.

I know. This is why I'm looking for help.
Do you know something similar as reference design?

O.k., fits perfectly my post #7 resource estimation :)

With a few clicks, you'll see that named founder of Leaf Alden LLC Leaf Sing is now operating NODAR Sensor https://www.nodarsensor.com/

Perhaps he can tell you if someone is maintaining the old design.
