I found this

http://www.antiquetelephones.co.uk/contents/en-uk/p11569_Electronic_Microphone_to_Fit_US_500_Series.html

these are in the UK for 500 type handsets. I have seen others that replace the entire mic cup but never these. At least they say "electrinic mic" so I assume the are not carbon mics. That means these from the UK will also work in trimlines, Sculpturas, 70s candlestick repros  and so many more that do not have the mic cup to replace.

Sorry no good answer, but when you are searching, Europeans usually call the transmitter for microphone or mikrofon  or Sprechkapsel     depending on where in Europe they come from. The very best electronic replacement I ever have tested was made for intercoms made for and marked Siedle, I know Siedle has been sold in the US

Unfortunately I don't know of any US suppliers, the only thing I could suggest is asking them directly if they're willing to divulge a supplier's info so you could buy some to sell over there or something...

Also, the same site has these:

http://www.antiquetelephones.co.uk/contents/en-uk/p864_700_series_microphone.html

Remove the red cap (designed to sit in a GPO 700-type Handset) and you have a module that would replace the entire transmitter assembly in a hardwired G-type handset... :)

And another site, they have what I have one of:

Just drops into the transmitter cup in place of a standard T1 transmitter, no alteration necessary... :)

I make my own electronic transmitter inserts.  See: http://www.classicrotaryphones.com/forum/index.php?topic=15950.msg186755#msg186755.

I've never dealt with American 'phones but they can be fitted to British ones without any modification.

I fioubnd these here but looks like 5000 Minimum.

It looks like one of those might be WE type and another looks like those use in Ericsson and Telcer (Bobo Phone)

Not sure which listed on that Alibaba link you are refering to so I posted all 5  below.

Yes, I never click on Alibaba as they are major exporters to companies that buy large quantities, and deal with shipping, import licenses, letters of credit, State Department approvals and any duties and/or taxes imposed. IIRC, Alibaba is a clearing house or brokerage company which does well in putting world level buyers in touch with all of the small manufacturing facilities in the far east.

Minimum order is way above the level ALL members on the forum would want to endure so while a good reference source to find something (which may have been imported to the US for sale at markup buy others - the once hard to fine Radio Shack spade lug crimper is a real good example of that in that were for sale on Alibaba but at great quantity, but now appear in the US an reasonable prices by the each).

I used to buy MNiniPCs from alibabba and their sister site AliExpress .I was able to buyy them a few at a time. They have proven to be solid units.

I found these rather odd looking elements . They look like WE compatibles but clear plastic cover. Wonder if these are carbon or not???

The same seller has these which appear to be speaker elements for trimlines although they say they are Mic elements

You can get electret microphones from Payphone.com (not sure if they are what you're looking for or not):

https://www.payphone.com/EMS-94-Electret-Condenser-Microphone.html

The description says:

QuoteThe newly improved EMS-94 Electret Condenser Microphone efficiently transmits a pure and clear sound. It has extra sensitivity with better reproduction fidelity. It eliminates the carbon granule packing problem. It is a solid state pre-amplifier that utilizes telephone power. It maintains constant line-level and improves the signal-to-noise ratio in all acoustic communications.

So based on that, it's not a carbon transmitter. Also, it's easy for anyone to buy from them (I've bought parts for my payphone from them before), whereas the other site that was mentioned (Audiosears) seems to be oriented toward selling to businesses. I don't see any "add to cart" option on their site, or even any pricing. Instead you get this:

QuoteElements are available in a variety of custom impedances that may require minimum purchase quantities and varying lead times - contact our sales department for more information and pricing.

If you're talking about the EMS-94, it's considered a carbon mic replacement. For one thing, that site is marketing them for payphones, and many, if not most, payphones originally came with carbon mics in a G-series handset (Western Electric payphones for example). For another thing, it says it "eliminates the carbon granule packing problem", and only people using it to replace a carbon mic would have had that problem to begin with. Also, this site sells them too (the older version with an integrated transmitter cup):

http://www.sandman.com/parts.html

And the description there is:

"EMS-94 Electronic Carbon Replacement with High Quality Sound"

I was going to order one from Payphone.com to try it out, until I saw the shipping cost. $20.04 to ship something that costs $5.50 and weighs 26 grams (less than an ounce). That's beyond ridiculous. It's because Fedex is their only shipping option, and Fedex's prices for shipping small items are outrageous. Any web store that sells small items needs to have a USPS shipping option.

It's funny that someone from Hong Kong can sell me 10 tone generator chips and ship them to Maine for a total cost of $8.96, but Fedex charges $20 just to ship an item of similar size and weight from Texas to Maine. For that matter, there are tons of small items you can buy on eBay, from China, with free shipping, for less than a dollar. For example, a 1/8" miniplug splitter for 77 cents:
