Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SFML-120-L2-L-D-A are qualified based on identical electrical and mechanical parameters. The substitution criteria are strictly limited to the following parameters, all of which must match the main part:

• Connector Type: Receptacle
• Number of Positions: 40
• Pitch - Mating: 0.050" (1.27mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Surface Mount
• 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
• Insulation Material: Liquid Crystal Polymer (LCP)
• Termination: Solder
• Fastening Type: Locking Ramp
• Features: Board Guide

The identified substitutes differ only in packaging configuration and moisture sensitivity classification, which do not affect electrical or mechanical performance in the application.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SFML-120-L2-L-D-A, SFML-120-T2-L-D-A, and SFML-120-02-L-D-A—are active production parts from Samtec Inc. with ROHS3 compliance and UL94 V-0 flammability certification. They are electrically and mechanically interchangeable for applications requiring 40-position, 0.050" pitch surface mount receptacle connectors with gold contacts, 3.2A per contact current rating, and 250VAC voltage rating across the -55°C to 125°C operating range.

Selection between these parts should be based on inventory availability and packaging requirements. The SFML-120-L2-L-D-A offers the highest current inventory at 1123 units. The SFML-120-T2-L-D-A and SFML-120-02-L-D-A provide alternative sourcing options with 999 and 874 units respectively. All parts carry identical electrical performance specifications and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Are SFML-120-L2-L-D-A, SFML-120-T2-L-D-A, and SFML-120-02-L-D-A electrically interchangeable?

A: Yes. All three parts share identical electrical specifications including 3.2A per contact current rating, 250VAC voltage rating, gold contact finish at 10.0µin (0.25µm) thickness, and operating temperature range of -55°C to 125°C.

Q: Are these parts mechanically interchangeable?

A: Yes. All three parts are 40-position receptacle connectors with 0.050" (1.27mm) pitch mating, 2-row configuration with 0.050" row spacing, surface mount termination, locking ramp fastening, and board guide features. They mount identically on PCBs.

Q: What is the difference between these part numbers?

A: The differences are limited to packaging configuration and moisture sensitivity classification. These variations do not affect electrical performance, mechanical fit, or thermal characteristics in the application.

Q: Are all three parts ROHS3 compliant?

A: Yes. SFML-120-L2-L-D-A, SFML-120-T2-L-D-A, and SFML-120-02-L-D-A are all ROHS3 compliant.

Q: Do all parts meet the same flammability standards?

A: Yes. All three parts carry UL94 V-0 material flammability rating.

Q: Which part should I select for new designs?

A: Any of the three parts is suitable for new designs. Selection should be based on current inventory availability and packaging requirements for your supply chain.
