SFC-140-T2-F-D Equivalent & Substitute Parts

Part Overview

The SFC-140-T2-F-D is an 80-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 maintains Active product status with full RoHS3 compliance and MSL 1 rating, making it suitable for high-reliability applications requiring compact interconnection solutions.

Identifying equivalent and substitute parts is necessary when addressing inventory constraints, lead time requirements, or design optimization needs while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFC-140-T2-F-D is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Position count (80 positions)
• Mating pitch (0.050" / 1.27mm)
• Row configuration (2 rows at 0.050" spacing)
• Mounting technology (Surface Mount)
• Electrical ratings (3.1A per contact, 350VAC minimum)
• Operating temperature range (-55°C ~ 125°C)
• Contact finish specification (Gold mating surface)
• Compliance certifications (RoHS3, MSL 1)

Substitute parts must maintain identical electrical performance, mechanical interface dimensions, and regulatory compliance status. Variations in non-critical features such as board guide presence do not affect core substitutability.

Parameter Comparison

Engineering Selection Recommendations

Both SFC-140-T2-F-D and SFC-140-T2-F-D-A maintain Active product status with identical electrical specifications, mechanical interfaces, and regulatory compliance. Selection between these parts should be based on inventory availability and lead time requirements. The SFC-140-T2-F-D-A includes a board guide feature; this design enhancement does not affect electrical compatibility or mating performance with standard Tiger Eye™ SFC series plugs.

Both parts carry ROHS3 compliance and MSL 1 rating, confirming suitability for moisture-sensitive environments without special handling requirements. ECCN classification as EAR99 applies uniformly across both variants.

Frequently Asked Questions (FAQ)

Q: Can SFC-140-T2-F-D-A be used as a direct replacement for SFC-140-T2-F-D?

A: Yes. Both parts are electrically and mechanically equivalent. The SFC-140-T2-F-D-A includes a board guide feature that enhances mechanical stability during mating but does not alter electrical performance or contact interface specifications.

Q: Are the mating interfaces identical between these two parts?

A: Yes. Both connectors feature identical 80-position, 0.050" pitch receptacle configurations with matching contact geometry, gold plating thickness, and electrical ratings. They mate with the same plug series.

Q: What is the significance of the board guide feature in the SFC-140-T2-F-D-A?

A: The board guide is a mechanical alignment feature that assists in connector positioning during assembly. It does not affect electrical performance, current capacity, or voltage ratings.

Q: Do both parts require identical PCB footprints?

A: Yes. Both parts share the same base product number (SFC-140) and surface mount termination pattern. PCB layouts are interchangeable.

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

A: No. Both parts carry identical RoHS3 compliance, MSL 1 rating, ECCN classification, and HTSUS codes.

Q: What is the current rating per contact for these connectors?

A: Both parts are rated for 3.1A per contact at 350VAC maximum.

Q: What is the operating temperature range?

A: Both parts operate across -55°C to 125°C.
