Substitute Part Grouping Explanation

The SFML-115-L2-S-D-A has one identified substitute within the Tiger Eye™ SFML series: SFML-115-T2-S-D-A. Substitution eligibility is determined by the following critical parameters that must remain identical:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 30
• Pitch - Mating: 0.050" (1.27mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Surface Mount
• Termination: Solder
• Contact Finish - Mating: Gold
• Current Rating: 3.2A per Contact
• Voltage Rating: 250VAC
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The difference between these parts lies in the fastening type designation (L2 versus T2), which represents a variation within the same connector family while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both SFML-115-L2-S-D-A and SFML-115-T2-S-D-A are Active status products from Samtec Inc. with identical electrical and mechanical specifications. Both connectors are ROHS3 compliant and carry UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications. Selection between these parts should be based on inventory availability and specific fastening type requirements defined by the application design. The SFML-115-T2-S-D-A currently has higher inventory availability (1013 Pcs) compared to SFML-115-L2-S-D-A (881 Pcs).

Frequently Asked Questions (FAQ)

Q: Are SFML-115-L2-S-D-A and SFML-115-T2-S-D-A electrically interchangeable?

A: Yes. Both connectors have identical electrical ratings: 3.2A per contact, 250VAC voltage rating, and operate across the same temperature range (-55°C ~ 125°C). The difference in part number designation (L2 versus T2) reflects a variation in fastening type but does not affect electrical performance.

Q: What is the significance of the L2 and T2 designations?

A: These designations indicate different fastening type variants within the Tiger Eye™ SFML series. Both maintain the same Locking Ramp fastening mechanism and are mechanically compatible for board-to-board or cable applications.

Q: Can these connectors be used in high-temperature applications?

A: Both connectors are rated for operating temperatures from -55°C to 125°C. Applications requiring operation outside this range require alternative connector selection.

Q: What is the pitch specification for these connectors?

A: Both connectors feature a 0.050" (1.27mm) mating pitch with 0.050" (1.27mm) row spacing. This fine-pitch specification is critical for high-density interconnect applications.

Q: Are these connectors RoHS compliant?

A: Yes. Both SFML-115-L2-S-D-A and SFML-115-T2-S-D-A are ROHS3 compliant and meet environmental regulatory requirements for restricted substances.

Q: What is the contact finish specification?

A: Both connectors feature gold-plated mating contacts with 30.0µin (0.76µm) thickness and tin-plated posts for solder termination.
