Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFML-120-T2-L-D-LC is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Arrangement: 40 positions in 2-row configuration
• Pitch Specifications: 0.050" (1.27mm) mating pitch and row spacing
• Mounting Technology: Surface mount solder termination
• Electrical Performance: 3.2A per contact at 250VAC minimum
• Environmental Compliance: UL94 V-0 flammability, RoHS3 compliance, -55°C to 125°C operating range
• Contact Finish: Gold-plated mating surface with 10.0µin (0.25µm) thickness

The SFML-120-02-L-D-LC qualifies as a direct substitute based on identical alignment across all critical parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

Both the SFML-120-T2-L-D-LC and SFML-120-02-L-D-LC maintain Active product status within the Tiger Eye™ SFML series. Selection between these parts should be based on inventory availability and supply chain requirements, as they are electrically and mechanically equivalent.

Both parts satisfy RoHS3 compliance requirements and carry identical environmental certifications (UL94 V-0, MSL 1). The SFML-120-02-L-D-LC currently maintains higher inventory availability (1143 pcs vs. 1058 pcs), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Are SFML-120-T2-L-D-LC and SFML-120-02-L-D-LC interchangeable in PCB designs?

A: Yes. Both connectors are functionally equivalent across all electrical, mechanical, and environmental parameters. They share identical pitch, position count, row configuration, contact ratings, and mounting specifications. PCB footprints and mating interfaces are identical.

Q: What does the difference in part number designation (T2 vs. 02) indicate?

A: The designation difference reflects internal Samtec product line variants within the SFML-120 base product family. Both variants maintain identical specifications for the parameters provided in this reference.

Q: Can I substitute these connectors in existing assemblies without design changes?

A: Yes. The connectors are mechanically and electrically equivalent with identical footprints, mating interfaces, and performance characteristics. No PCB redesign or assembly process modifications are required.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical RoHS3 compliance status, UL94 V-0 flammability rating, MSL 1 moisture sensitivity level, and export classification (EAR99). Environmental operating ranges and electrical ratings are identical.

Q: Which part should I select for new designs?

A: Either part is suitable for new designs. Selection may be based on current inventory availability or supplier preference. Both maintain Active product status with equivalent long-term availability expectations.
