Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the T2M-105-01-L-D-RA is determined by strict equivalence across the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 10
• Number of Rows: 2
• Pitch - Mating: 0.079" (2.00mm)
• Row Spacing - Mating: 0.079" (2.00mm)
• Mounting Type: Through Hole, Right Angle
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Material: Phosphor Bronze
• Insulation Material: Liquid Crystal Polymer (LCP)
• Current Rating: 3.8A
• Operating Temperature: -55°C ~ 125°C

The substitute part T2M-105-01-L-D-RA-WT meets all these criteria. The only documented difference is the addition of solder retention features in the substitute variant, which represents an enhancement to the base design without altering core electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both T2M-105-01-L-D-RA and T2M-105-01-L-D-RA-WT are active products from Samtec Inc. with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on application-specific requirements:

The T2M-105-01-L-D-RA-WT variant includes solder retention features, which provide enhanced mechanical stability during soldering processes and may reduce rework requirements in high-volume manufacturing environments. Both parts maintain identical electrical performance, thermal ratings, and contact specifications.

Current inventory levels support either selection: T2M-105-01-L-D-RA has 1259 pieces in stock, while T2M-105-01-L-D-RA-WT has 1767 pieces in stock.

Frequently Asked Questions (FAQ)

Q: Are T2M-105-01-L-D-RA and T2M-105-01-L-D-RA-WT electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including current rating (3.8A), operating temperature range (-55°C ~ 125°C), contact material (Phosphor Bronze), and contact finish (Gold mating surface, Tin post finish).

Q: What is the functional difference between these two parts?

A: The T2M-105-01-L-D-RA-WT includes solder retention features. This is a manufacturing enhancement that does not alter electrical or mechanical compatibility. The base connector geometry, pitch, and contact configuration remain identical.

Q: Can I use T2M-105-01-L-D-RA-WT as a direct replacement for T2M-105-01-L-D-RA in existing designs?

A: Yes. The parts are mechanically and electrically equivalent. The solder retention feature in the -WT variant is a design enhancement that improves soldering reliability without requiring design changes.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both T2M-105-01-L-D-RA and T2M-105-01-L-D-RA-WT are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What is the pitch specification for these connectors?

A: Both parts feature a 2.00mm (0.079") mating pitch with 2.00mm row spacing. This is the standard spacing for the Tiger Eye™ T2M series 10-position, 2-row header configuration.

Q: Are there any packaging differences between these parts?

A: No. Both parts are supplied in tube packaging as standard.
