Separation SID's with same initial segment

Hi all,

Not new here, but now with an account . I have a question regarding the minimum departure separation is used by different ANSP's. How do you guys sequence and separate the following;

What if some of the SIDs for a specific runway have the same 'initial segment' before turning towards their specific basic indicator. Do you use the same time separation as considered for the same SIDs flown by aircraft behind each other in the departure sequence? For instance;

SID A1B: after departure climb straight ahead, at 2 'XXX' DME 2 turn left to track 045 and intercept 'ZZZ' R-180 proceed to 'QQQ' and proceed to 'GGG'.
SID B1B: after departure climb straight ahead, at 2 'XXX' DME 2 turn left to track 045 and intercept 'ZZZ' R-180 proceed to 'QQQ' and proceed to 'LLL'.

Initial segment is exactly the same, but they are considered as 'different' SIDs. How are those separated? 1 or 2 minutes? And to be sure I am NOT talking about wake turbulence minima.

Thanks all for the information and reply
