Parameter Comparison

Engineering Selection Recommendations

All three parts—SFM-120-T2-L-D-A-P-TR, SFM-120-02-L-D-A-K-TR, and SFM-120-02-L-D-A-P-TR—are active production parts with ROHS3 compliance and UL94 V-0 flammability certification. They share identical electrical ratings, mechanical dimensions, and environmental specifications. Selection between these parts should be based on inventory availability and internal connector architecture requirements specific to your application. All parts are packaged in Tape & Reel format suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can SFM-120-02-L-D-A-K-TR and SFM-120-02-L-D-A-P-TR be used interchangeably with SFM-120-T2-L-D-A-P-TR?

A: Yes. All three parts share identical electrical specifications (3.2A per contact, 250VAC), mechanical dimensions (40 positions, 0.050" pitch, 2 rows), contact materials (beryllium copper with gold plating), and environmental ratings (-55°C to 125°C, UL94 V-0). Differences in the part number reflect internal connector architecture variations that do not affect electrical or mechanical compatibility.

Q: What is the significance of the part number variations between these substitutes?

A: The second position code in the part number (T2 versus 02) indicates internal connector design variations within the Tiger Eye™ SFM series. All variants maintain the same 40-position, 0.050" pitch receptacle configuration and are fully compatible for board-to-board or cable applications.

Q: Are all three parts suitable for surface mount assembly?

A: Yes. All three parts feature surface mount termination with solder connections and include board guide and pick-and-place features for automated assembly processes.

Q: What are the mated stacking height options for these connectors?

A: All three parts support the same mated stacking heights: 6.15mm, 6.30mm, 7.92mm, 8.08mm, 9.70mm, 9.86mm, 11.61mm, and 11.76mm.

Q: Do these parts have any moisture sensitivity concerns?

A: No. All three parts are rated at Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.
