Substitute Part Grouping Explanation

Substitution eligibility for the SFM-115-L2-S-D-LC is determined by strict equivalence across the following critical parameters:

Connector type (Receptacle)
Contact type (Female Socket)
Number of positions (30)
Pitch - mating (0.050" / 1.27mm)
Number of rows (2)
Row spacing - mating (0.050" / 1.27mm)
Mounting type (Surface Mount)
Termination method (Solder)
Fastening type (Push-Pull)
Contact finish - mating (Gold)
Current rating (3.2A per Contact)
Voltage rating (250VAC)
Operating temperature range (-55°C ~ 125°C)
Material flammability rating (UL94 V-0)
RoHS compliance (ROHS3)

The substitute part SFM-115-02-S-D-LC meets all these criteria, confirming direct substitutability within the Tiger Eye™ SFM series.
