Key Parameters

Substitute Part Grouping Explanation

Substitution for the SFM-107-03-S-D-EM is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Number of positions (14)
• Pitch configuration (0.050" mating pitch, 0.050" row spacing)
• Number of rows (2)
• Mounting method (Through Hole)
• Contact finish specifications (Gold mating, Tin post)
• Electrical ratings (3.2A per contact, 250VAC)
• Operating temperature range (-55°C ~ 125°C)
• Compliance certifications (UL94 V-0, ROHS3)

The SFM-107-03-S-D qualifies as a direct substitute based on identical alignment across all these parameters.

Parameter Comparison

Engineering Selection Recommendations

The SFM-107-03-S-D serves as a direct equivalent to the SFM-107-03-S-D-EM. Both parts maintain identical electrical, mechanical, and thermal specifications. Selection between these two part numbers should be based on availability and supply chain requirements, as both are active products from Samtec Inc. with ROHS3 compliance and UL94 V-0 flammability certification. No performance trade-offs exist between the two variants.
