is reusable good for 200lines of code in reactjs

So I m going to have 3 different component with different Imgs for each component and texts too like ( different for each titles or names) So I was wondering i can do like Fetch from Mongodb and use useNavigate to pass with state value like this

js 
const navigation= useNavigate ();
navigation (`${val.name}` , { state : val })

js 
const navigation= useNavigate ();
navigation (`${val.name}` , { state : val })

Here val is the data fetch from backend , so I'm using val.name as routes so it will be different routes For ex , if I click two it will navigate to /two and if I click one , it will nav to /one and pass different values for different routes And I use useLocation to get the values from that So my Question is All the components have same design but different Imgs and texts Would u guys think having 200+ lines of code as reusable component Or should I try useContext or should I go with useNavigate and useLocation ??

need help with mongodb

My collection document look like this

{
_id : 1,
hotelName:"Burger King",
cost : 200
},
{ 
_id : 2,
hotelName:"misu",
cost : 200
}

{
_id : 1,
hotelName:"Burger King",
cost : 200
},
{ 
_id : 2,
hotelName:"misu",
cost : 200
}

Express code :

js 
Hotelname ="Misu" 
await Model.find({
hotelName : { 
   $regex : Hotelname , $options : 'i' } })

js 
Hotelname ="Misu" 
await Model.find({
hotelName : { 
   $regex : Hotelname , $options : 'i' } })

I use regEx to remove white spaces on hotelName variable and make it as lower case too before using on $regex query So the problem is if I search Misu it works but it won't work when Burger King because it has space between the words ! Is there any solution or should I change the values in document
