TE acquired Potter & Brumfield, a well-known relay company, quite a long time ago. Many older P&B relays, such as T7CV5D-12, have been phased out and obsoleted over time. These relays are still in use in older equipment that needs maintenance, though - if the relays are obsolete, how can you fix your broken machine?
Check out JJM2W-12V, from Panasonic. This relay is one our team has confirmed to be similar enough to work in most typical repair applications. We cannot guarantee this, and you should always verify compatibility with your equipment prior to fully trusting a cross, but JJM2W-12V should be a great place to start for most repair needs.
