• Position Count & Pitch: 100 positions at 0.050" (1.27mm) mating pitch
• Row Configuration: 2 rows with 0.050" (1.27mm) row spacing
• Mounting & Termination: Surface mount with solder termination
• Electrical Ratings: 3.2A per contact, 250VAC
• Contact Material & Finish: Beryllium copper with gold mating finish (30.0µin / 0.76µm)
• Insulation Material: Liquid Crystal Polymer (LCP)
• Fastening Type: Push-Pull mechanism with board lock feature
• Compliance: RoHS3 compliant, REACH unaffected

The substitute part SFM-150-02-S-D-LC maintains identical specifications across all critical parameters, confirming direct substitution capability within the Tiger Eye™ SFM series.

Parameter Comparison

Engineering Selection Recommendations

Both the SFM-150-L2-S-D-LC and SFM-150-02-S-D-LC maintain active product status within the Tiger Eye™ SFM series. Each part carries identical RoHS3 compliance certification and REACH unaffected status, confirming regulatory equivalence for applications requiring environmental compliance. The SFM-150-02-S-D-LC currently maintains higher inventory availability (1420 pcs vs. 957 pcs), which may influence supply chain decisions without affecting technical performance or compatibility. Both parts are suitable for direct substitution in board-to-board and cable connector applications requiring 100-position, 0.050" pitch surface mount receptacles with gold-plated contacts and push-pull fastening.

Frequently Asked Questions (FAQ)

Q: Can SFM-150-02-S-D-LC be used as a direct replacement for SFM-150-L2-S-D-LC?

A: Yes. Both parts are functionally equivalent across all critical electrical, mechanical, and environmental parameters. They share identical position count, pitch, row configuration, contact ratings, and compliance certifications.

Q: Are there any differences in mated stacking heights between these parts?

A: No. Both parts provide identical mated stacking height options: 6.15mm, 6.30mm, 7.92mm, 8.08mm, 9.70mm, 9.86mm, 11.61mm, and 11.76mm.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both SFM-150-L2-S-D-LC and SFM-150-02-S-D-LC are RoHS3 compliant, REACH unaffected, and carry UL94 V-0 flammability ratings.

Q: What is the difference between the part numbers L2 and 02 designations?

A: The L2 and 02 designations represent different internal Samtec product variants within the SFM-150 base product family. Both variants maintain identical electrical and mechanical specifications for the 100-position, 0.050" pitch receptacle configuration.

Q: Are the contact materials and finishes identical?

A: Yes. Both parts use beryllium copper contacts with 30.0µin (0.76µm) gold mating finish and tin post finish, ensuring equivalent electrical performance and reliability.

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

A: Both parts are rated for -55°C to 125°C operating temperature range, suitable for standard industrial and commercial applications within this thermal envelope.
