Key Parameters

Substitute Part Grouping Explanation

Substitution within the Tiger Eye™ SFM connector family is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Number of positions (50)
• Pitch specification (0.050" / 1.27mm)
• Row configuration (2 rows)
• Mounting method (Through Hole)
• Contact finish (Gold mating surface)
• Electrical ratings (3.2A per contact, 250VAC)
• Operating temperature range (-55°C ~ 125°C)
• Material compliance (UL94 V-0, ROHS3)

The identified substitute SFM-125-03-L-D-A maintains identical specifications across all these parameters, confirming direct substitutability within the same connector series.

Parameter Comparison

Engineering Selection Recommendations

Both SFM-125-L3-L-D-A and SFM-125-03-L-D-A are Active status products within the Tiger Eye™ SFM series. Selection between these parts is based on inventory availability and supply chain requirements rather than technical differentiation. The SFM-125-03-L-D-A currently maintains higher inventory (1261 units) compared to SFM-125-L3-L-D-A (894 units). Both parts meet ROHS3 compliance and UL94 V-0 flammability requirements. Electrical performance, mechanical dimensions, and environmental operating specifications are identical across both part numbers.

Frequently Asked Questions (FAQ)

Q: Are SFM-125-L3-L-D-A and SFM-125-03-L-D-A electrically interchangeable?
