SFM-140-T2-L-D-A-P-TR Equivalent & Substitute Parts

Part Overview

The SFM-140-T2-L-D-A-P-TR is an 80-position receptacle connector from Samtec Inc.'s Tiger Eye™ SFM series, designed for surface mount board-to-board or cable applications. This connector features 0.050" (1.27mm) pitch mating contacts with gold plating, push-pull fastening, and operates across -55°C to 125°C. The part is actively produced and ROHS3 compliant. Identifying equivalent and substitute parts is necessary when addressing packaging format requirements, inventory availability, or specific application constraints while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

The SFM-140-02-L-D-A-K-TR qualifies as a direct substitute based on identical electrical and mechanical parameters. Both parts share the same core specifications: 80-position receptacle configuration, 0.050" (1.27mm) pitch, 2-row layout, surface mount termination, gold mating contact finish, 3.2A per contact current rating, and 250VAC voltage rating. The substitution is valid across the full operating temperature range (-55°C to 125°C) and material flammability rating (UL94 V-0).

The primary difference between these parts is packaging format: the main part (SFM-140-T2-L-D-A-P-TR) is supplied in Tape & Reel (TR) format, while the substitute (SFM-140-02-L-D-A-K-TR) is supplied in Cut Tape (CT) format. This distinction affects procurement and assembly workflows but does not impact electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the SFM-140-T2-L-D-A-P-TR and SFM-140-02-L-D-A-K-TR are active products from Samtec Inc. with ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and procurement workflow:

Select SFM-140-T2-L-D-A-P-TR (Tape & Reel) for high-volume automated assembly operations requiring continuous reel feeding and pick-and-place machine compatibility.

Select SFM-140-02-L-D-A-K-TR (Cut Tape) for lower-volume applications, manual assembly processes, or when cut tape packaging aligns with inventory management practices.

Both parts maintain full compatibility with mating connectors and PCB layouts designed for the SFM-140 base product number. No electrical performance, thermal rating, or compliance differences exist between these variants.

Frequently Asked Questions (FAQ)

Q: Are SFM-140-T2-L-D-A-P-TR and SFM-140-02-L-D-A-K-TR electrically identical?

A: Yes. Both parts are 80-position receptacle connectors with identical electrical ratings (3.2A per contact, 250VAC), operating temperature range (-55°C to 125°C), contact materials (beryllium copper with gold mating finish), and all mechanical dimensions including pitch (0.050"), row spacing (0.050"), and mated stacking heights.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on a continuous reel suitable for automated pick-and-place assembly. Cut Tape packaging supplies components in individual tape segments, typically used for lower-volume or manual assembly processes. The connector itself is identical; only the delivery format differs.

Q: Can I use SFM-140-02-L-D-A-K-TR as a direct replacement for SFM-140-T2-L-D-A-P-TR in existing designs?

A: Yes, from an electrical and mechanical standpoint. The connector footprint, pin configuration, and performance characteristics are identical. Verify that your assembly process can accommodate Cut Tape packaging if switching from Tape & Reel format.

Q: Are both parts RoHS compliant?

A: Yes. Both SFM-140-T2-L-D-A-P-TR and SFM-140-02-L-D-A-K-TR are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What mating connector should I use with these receptacles?

A: Both parts are designed for the Tiger Eye™ SFM series. Consult Samtec documentation for compatible plug connectors matching the 80-position, 0.050" pitch, 2-row configuration.
