Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFMC-111-02-L-D is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle) and contact type (Female Socket)
• Number of positions (22) and row configuration (2 rows)
• Pitch specifications (0.050" mating pitch and 0.050" row spacing)
• Mounting method (Surface Mount) and termination type (Solder)
• Fastening mechanism (Push-Pull)
• Operating temperature range (-55°C ~ 125°C)
• Current rating (2.9A per contact)
• Insulation material (Liquid Crystal Polymer)
• Contact finish on mating surface (Gold, 10.0µin thickness)
• Compliance certifications (UL94 V-0, ROHS3)

The substitute part SFMC-111-T2-L-D-P meets all these critical parameters. Variations in contact material (Beryllium Copper versus Phosphor Bronze) and manufacturing process features (Pick and Place capability) do not affect functional interchangeability when all electrical and mechanical specifications remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both SFMC-111-02-L-D and SFMC-111-T2-L-D-P are active production parts from Samtec Inc. with equivalent electrical and mechanical specifications. Selection between these parts should be based on:

Availability and Lead Time: SFMC-111-T2-L-D-P currently has higher inventory (1696 units) compared to SFMC-111-02-L-D (891 units), making it suitable for applications requiring immediate procurement or high-volume orders.

Compliance and Certifications: Both parts meet ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity requirements, ensuring suitability for regulated and high-reliability applications.

Manufacturing Process: SFMC-111-T2-L-D-P includes Pick and Place capability, which may provide advantages in automated assembly environments. This does not affect electrical or mechanical interchangeability.

Contact Material Variation: The difference in contact material (Beryllium Copper versus Phosphor Bronze) does not impact functional compatibility when both parts maintain identical mating surface finish (Gold, 10.0µin) and current rating (2.9A per contact).

Frequently Asked Questions (FAQ)

Q: Are SFMC-111-02-L-D and SFMC-111-T2-L-D-P mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 22-position configuration, 0.050" pitch, 2-row layout, surface mount termination, and push-pull fastening. Physical dimensions and mounting footprints are equivalent.

Q: Can these parts be used interchangeably in the same PCB design?

A: Yes. The connectors have identical insulation height (0.185"), contact shape (square), and mounting type (surface mount solder termination). No PCB layout modifications are required when substituting between these parts.

Q: What is the difference in contact material, and does it affect performance?

A: SFMC-111-02-L-D uses Beryllium Copper contacts while SFMC-111-T2-L-D-P uses Phosphor Bronze contacts. Both materials are rated for 2.9A per contact with identical gold mating surface finish (10.0µin). The contact material difference does not affect electrical performance or current-carrying capacity in this application.

Q: Are both parts suitable for high-reliability applications?

A: Yes. Both parts meet UL94 V-0 flammability rating, ROHS3 compliance, and MSL 1 moisture sensitivity requirements. Both operate across the full -55°C to 125°C temperature range, supporting high-reliability and industrial applications.

Q: What does "Pick and Place" capability mean for SFMC-111-T2-L-D-P?

A: Pick and Place capability indicates the part is optimized for automated assembly processes using robotic placement equipment. This manufacturing feature does not affect the connector's electrical or mechanical performance in the final assembly.

Q: Which part should I select for new designs?

A: Both parts are active and suitable for new designs. Selection should be based on procurement availability, inventory levels, and assembly process requirements. SFMC-111-T2-L-D-P offers higher current inventory and automated assembly compatibility.
