• Number of Positions: 90
• Pitch - Mating: 0.050" (1.27mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Connector Type: Receptacle
• Contact Type: Female Socket
• Mounting Type: Surface Mount
• Termination: Solder
• Current Rating: 3.2A per Contact
• Voltage Rating: 250VAC
• Operating Temperature: -55°C ~ 125°C
• Contact Finish - Mating: Gold
• Insulation Material: Liquid Crystal Polymer (LCP)
• Material Flammability Rating: UL94 V-0

Parameter Comparison

Engineering Selection Recommendations

All three parts—SFM-145-T2-S-D-LC, SFM-145-02-S-D-LC, and SFM-145-L2-S-D-LC—are Active status products from Samtec Inc. within the Tiger Eye™ SFM series. Each part is ROHS3 compliant and carries UL94 V-0 material flammability certification. The electrical and mechanical specifications are identical across all three variants, confirming direct interchangeability for 90-position, 0.050" pitch surface mount receptacle applications.

Selection between these parts should be based on inventory availability and lead time requirements. SFM-145-02-S-D-LC currently has the highest inventory level at 2100 units, followed by SFM-145-T2-S-D-LC at 946 units and SFM-145-L2-S-D-LC at 872 units.

Frequently Asked Questions (FAQ)

Q: Are SFM-145-T2-S-D-LC, SFM-145-02-S-D-LC, and SFM-145-L2-S-D-LC directly interchangeable?

A: Yes. All three parts share identical electrical and mechanical specifications, including 90 positions, 0.050" (1.27mm) pitch, 2-row configuration, 3.2A per contact current rating, and 250VAC voltage rating. They are direct substitutes within the SFM-145 base product family.

Q: What is the difference between these part numbers?

A: The differences are encoded in the part number suffixes (T2, 02, and L2). These designations reflect internal Samtec product variants within the same electrical and mechanical specification class. All other parameters, including contact configuration, termination method, and performance ratings, remain identical.

Q: Are all three parts ROHS3 compliant?

A: Yes. SFM-145-T2-S-D-LC, SFM-145-02-S-D-LC, and SFM-145-L2-S-D-LC are all ROHS3 compliant with UL94 V-0 material flammability rating.

Q: What is the Moisture Sensitivity Level for these connectors?

A: All three parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

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

A: Yes. All three parts are rated for operating temperatures from -55°C to 125°C, supporting both industrial and extended temperature range applications.

Q: What is the current and voltage rating for each contact?

A: Each contact is rated for 3.2A at 250VAC across all three part variants.
