Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SFM-105-T2-L-D-A-P-TR are identified based on strict equivalence of the following critical parameters:

• Connector Type: Receptacle
• Number of Positions: 10
• Pitch - Mating: 0.050" (1.27mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Surface Mount
• Contact Type: Female Socket
• 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)
• Contact Material: Beryllium Copper
• Series: Tiger Eye™ SFM
• Base Product Number: SFM-105
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitutes differ only in fastening type designation (P vs. K suffix), which represents alternative push-pull latch configurations within the same connector family. All electrical, mechanical, and environmental specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SFM-105-T2-L-D-A-P-TR, SFM-105-02-L-D-A-P-TR, and SFM-105-02-L-D-A-K-TR—maintain Active product status and full ROHS3 compliance. Selection between these parts is determined by fastening type requirement and inventory availability:

• SFM-105-T2-L-D-A-P-TR: Primary specification with P-type push-pull latch. 962 units in stock.
• SFM-105-02-L-D-A-P-TR: Equivalent substitute with P-type push-pull latch. 1441 units in stock.
• SFM-105-02-L-D-A-K-TR: Equivalent substitute with K-type push-pull latch. 3589 units in stock.

All parts satisfy identical electrical performance (3.2A per contact, 250VAC), thermal requirements (-55°C ~ 125°C), and mechanical specifications. The choice between P and K fastening types depends on mating connector compatibility and application-specific engagement requirements. Higher inventory availability exists for the K-type variant.

Frequently Asked Questions (FAQ)

Q: Can SFM-105-02-L-D-A-P-TR be used as a direct replacement for SFM-105-T2-L-D-A-P-TR?

A: Yes. Both parts are 10-position receptacle connectors with identical electrical ratings (3.2A per contact, 250VAC), mechanical pitch (0.050"), mounting type (surface mount), and environmental specifications (-55°C ~ 125°C). The primary difference is the connector designation within the Tiger Eye™ SFM series, but all critical parameters are equivalent.

Q: What is the difference between the P and K fastening type designations?

A: The P and K suffixes represent different push-pull latch configurations within the Tiger Eye™ SFM connector family. Both provide equivalent mechanical engagement and retention. Selection depends on compatibility with the mating connector type and application-specific engagement requirements.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts—SFM-105-T2-L-D-A-P-TR, SFM-105-02-L-D-A-P-TR, and SFM-105-02-L-D-A-K-TR—are ROHS3 compliant and suitable for applications requiring RoHS certification.

Q: What is the moisture sensitivity level for these connectors?

A: All three parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements.

Q: Can these connectors be used interchangeably in the same PCB design?

A: Yes, provided the mating connector is compatible with the selected fastening type (P or K). All three parts share identical footprints, pitch spacing (0.050"), and surface mount pad configurations, allowing direct PCB layout compatibility.

Q: What are the available mated stacking heights?

A: All three parts support identical mated stacking heights: 6.15mm, 6.30mm, 7.92mm, 8.08mm, 9.70mm, 9.86mm, 11.61mm, and 11.76mm, providing flexibility for various application stack-up requirements.
