Substitute Part Grouping Explanation

The SFMC-117-L2-S-D has one identified substitute: SFMC-117-02-S-D. Both parts are substitutable based on the following critical parameters that remain identical:

• Connector type: Receptacle with female socket contacts
• Position count: 34 positions
• Pitch specification: 0.050" (1.27mm) mating pitch
• Row configuration: 2 rows with 0.050" (1.27mm) row spacing
• Mounting method: Surface mount with solder termination
• Contact material: Beryllium copper with gold mating finish (30.0µin / 0.76µm)
• Current capacity: 2.9A per contact
• Operating temperature range: -55°C ~ 125°C
• Insulation material: Liquid Crystal Polymer (LCP)
• Fastening type: Push-pull mechanism
• Compliance: ROHS3 compliant, UL94 V-0 rated

The substitution is valid within the Tiger Eye™ SFMC series where these parameters define functional equivalence for board-to-board and cable interconnect applications.

Parameter Comparison

Engineering Selection Recommendations

Both SFMC-117-L2-S-D and SFMC-117-02-S-D are active production parts 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-117-02-S-D offers higher stock levels (1188 units versus 770 units), which may provide supply chain advantages for high-volume applications. Both parts maintain identical electrical and mechanical specifications, ensuring direct functional interchangeability in board-to-board and cable interconnect designs operating within the -55°C to 125°C temperature range.

Frequently Asked Questions (FAQ)

Q: Are SFMC-117-L2-S-D and SFMC-117-02-S-D mechanically interchangeable?
