Most types of desktop computer parts are agnostic of the vendor. For example, you can use a DDR RAM from any vendor on a motherboard from any vendor, as long as they have the same standards.
If I search eBay for TPM Module, top list shows ASUS, Gigabyte, or MSI. ASUS' contains "for ASUS motherboards". This looks as if it would only work for ASUS' motherboards. Can I buy a TPM module from any vendor, or should I buy a TPM module from the same vendor as that of the motherboard?
