Key Parameters

Substitute Part Grouping Explanation

The SFMC-150-L3-S-D qualifies as a direct substitute for the SFMC-150-03-S-D based on the following critical parameters:

• Connector Type & Position Count: Both are 100 position receptacles within the Tiger Eye™ SFMC series
• Pitch & Row Configuration: Identical 0.050" (1.27mm) mating pitch with 2-row layout
• Mounting & Termination: Both use through-hole solder termination
• Electrical Performance: Matching 2.9A per contact current rating
• Environmental Specifications: Identical -55°C ~ 125°C operating temperature range
• Contact Finish: Both feature gold-plated mating contacts with 30.0µin (0.76µm) thickness
• Compliance: Both are ROHS3 compliant with UL94 V-0 flammability rating
• Insulation Material: Both use Liquid Crystal Polymer (LCP) with black insulation

The substitution is based on mechanical and electrical parameter equivalence within the same product series.

Parameter Comparison

Engineering Selection Recommendations

Both the SFMC-150-03-S-D and SFMC-150-L3-S-D maintain Active product status with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on inventory availability and supply chain requirements. The SFMC-150-L3-S-D offers higher stock availability at 1197 units compared to 675 units for the SFMC-150-03-S-D. Both parts are suitable for applications requiring 100 position, 0.050" pitch board-to-board or cable connectivity with 2.9A per contact current capacity across the -55°C to 125°C operating range.
