Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFM-120-L2-S-D-P is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Position count (40 positions)
• Mating pitch (0.050" / 1.27mm)
• Row configuration (2 rows at 0.050" spacing)
• Mounting method (Surface Mount)
• Electrical ratings (3.2A per contact, 250VAC)
• Operating temperature range (-55°C ~ 125°C)
• Contact finish specification (Gold mating surface)
• Compliance certifications (ROHS3, UL94 V-0)

The identified substitute SFM-120-02-S-D-P maintains identical specifications across all these parameters, confirming direct substitutability within the Tiger Eye™ SFM series.
