SFC-120-T2-LM-D-A Equivalent & Substitute Parts

Part Overview

The SFC-120-T2-LM-D-A is a 40-position receptacle connector from Samtec Inc.'s Tiger Eye™ SFC series, designed for surface mount board-to-board or cable applications. This connector features 0.050" (1.27mm) pitch mating with gold-plated female socket contacts rated for 3.1A per contact at 350VAC. The part is currently active in production with 802 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector interface, allowing for design flexibility and supply chain alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFC-120-T2-LM-D-A is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle) and contact type (Female Socket)
• Position count (40 positions) and row configuration (2 rows)
• Mating pitch (0.050" / 1.27mm) and row spacing (0.050" / 1.27mm)
• Mounting technology (Surface Mount with solder termination)
• Electrical ratings (3.1A per contact, 350VAC minimum)
• Operating temperature range (-55°C ~ 125°C minimum)
• Contact finish specification (Gold mating surface)
• Compliance certifications (ROHS3, MSL 1)

The identified substitute part SFC-120-T2-L-D-A maintains all these parameters within the same Tiger Eye™ SFC series, differing only in non-critical designation elements that do not affect electrical or mechanical interface compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the SFC-120-T2-LM-D-A and SFC-120-T2-L-D-A are active production parts with full ROHS3 compliance and MSL 1 rating. Selection between these parts is based on availability and supply chain considerations rather than electrical or mechanical differences. The SFC-120-T2-L-D-A currently maintains higher inventory (889 units versus 802 units), which may provide supply chain advantages for high-volume applications. Both parts are suitable for applications requiring 40-position, 0.050" pitch surface mount receptacle connectors with gold contact finish and 3.1A per contact current capacity.

Frequently Asked Questions (FAQ)

Q: Can SFC-120-T2-L-D-A be used as a direct replacement for SFC-120-T2-LM-D-A?

A: Yes. Both parts maintain identical electrical and mechanical interface parameters, including position count, pitch, row spacing, current rating, voltage rating, and operating temperature range. The parts are electrically and mechanically interchangeable.

Q: What determines whether a part qualifies as a substitute?

A: Substitution is based on equivalence across connector type, contact type, position count, row configuration, mating pitch, row spacing, mounting technology, current and voltage ratings, operating temperature range, contact finish specification, and compliance certifications. All these parameters must match or exceed the original part specification.

Q: Are there differences in the part numbers that affect compatibility?

A: The part number designations differ only in non-critical elements that do not affect the mating interface or electrical performance. Both parts belong to the same Tiger Eye™ SFC series and maintain identical functional specifications.

Q: What is the significance of the MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. Both parts can be stored and handled under standard conditions without special moisture management protocols.

Q: Are both parts RoHS compliant?

A: Yes. Both SFC-120-T2-LM-D-A and SFC-120-T2-L-D-A are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic components.
