• Contact Type: Male Pin
• Number of Positions: 8
• Number of Rows: 1
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Surface Mount, Right Angle
• Termination: Solder
• Contact Length - Mating: 0.230" (5.84mm)
• Insulation Height: 0.120" (3.05mm)
• Contact Shape: Square
• Contact Finish - Mating: Gold at 10.0µin (0.25µm)
• Contact Finish - Post: Tin
• Contact Material: Phosphor Bronze
• Insulation Material: Liquid Crystal Polymer (LCP)
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• Insulation Color: Black
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• Product Status: Active

Variations among substitute parts are limited to optional mechanical features (Board Guide, Board Lock) and REACH compliance status, which do not affect core electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All four parts maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. Selection among TSM-108-01-LM-SH, TSM-108-01-L-SH, TSM-108-01-L-SH-A, and TSM-108-01-L-SH-LC is determined by optional mechanical features and REACH compliance requirements specific to the application.

TSM-108-01-L-SH-A includes a Board Guide feature and carries REACH Affected status, making it suitable for applications requiring enhanced mechanical alignment during mating operations and subject to REACH regulatory frameworks.

TSM-108-01-L-SH-LC incorporates a Board Lock feature, providing mechanical retention after mating, and is appropriate for applications requiring positive connection security.

TSM-108-01-L-SH offers baseline functionality without additional mechanical features and maintains REACH Unaffected status.

TSM-108-01-LM-SH serves as the reference part with no specified additional features.

All parts are electrically and mechanically interchangeable within the TSM series for standard board-to-board or cable connection applications operating within the -55°C to 125°C temperature range.

Frequently Asked Questions (FAQ)

Q: Are TSM-108-01-LM-SH and TSM-108-01-L-SH electrically identical?

A: Yes. Both parts share identical electrical specifications including contact material (Phosphor Bronze), contact finish (Gold at 10.0µin mating, Tin post), pitch (0.100" / 2.54mm), and operating temperature range (-55°C ~ 125°C).

Q: What is the difference between TSM-108-01-L-SH-A and TSM-108-01-L-SH-LC?

A: TSM-108-01-L-SH-A includes a Board Guide feature for enhanced alignment during mating. TSM-108-01-L-SH-LC includes a Board Lock feature for mechanical retention after mating. Both maintain identical electrical specifications.

Q: Can I substitute TSM-108-01-L-SH-A in place of TSM-108-01-LM-SH?

A: Yes, for electrical and mechanical compatibility. However, TSM-108-01-L-SH-A carries REACH Affected status, whereas TSM-108-01-LM-SH does not specify REACH status. Verify REACH compliance requirements for your application before substitution.

Q: Do all substitute parts maintain the same solder termination and surface mount orientation?

A: Yes. All parts feature solder termination and surface mount right-angle mounting type, ensuring PCB assembly compatibility without modification.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates these connectors have unlimited shelf life without moisture bake-out requirements, simplifying inventory management and reducing handling constraints.

Q: Are all parts packaged identically?

A: All parts are supplied in Tube packaging as specified by Samtec Inc.

Q: What is the mating contact length specification?

A: All parts maintain a mating contact length of 0.230" (5.84mm), ensuring consistent mating depth and contact engagement across the entire substitute group.
