Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TML-110-01-G-D is determined by strict alignment of the following critical mating interface parameters:

Primary Substitution Criteria:

• Pitch - Mating: 0.050" (1.27mm) — exact match required
• Number of Positions: 20 — exact match required
• Number of Rows: 2 — exact match required
• Row Spacing - Mating: 0.100" (2.54mm) — exact match required
• Connector Type: Header — exact match required
• Contact Type: Male Pin — exact match required
• Mounting Type: Through Hole — exact match required
• Termination: Solder — exact match required

The identified substitute parts (104068-1 and 5-104068-1) from TE Connectivity AMP Connectors meet all primary substitution criteria. Both parts are manufactured within the AMPMODU System 50 series and maintain identical mating interface geometry, allowing direct mechanical and electrical compatibility in board-to-board applications. Variations in secondary parameters such as shrouding design (4-wall vs. 2-wall), contact finish composition, and insulation material do not affect the core mating function when the primary criteria are satisfied.

Engineering Selection Recommendations

TML-110-01-G-D (Primary Part):

• Active production status with established supply chain
• ROHS3 compliant for regulated applications
• Extended operating temperature range (-55°C to 125°C) suitable for industrial and aerospace environments
• 4-wall shrouding provides enhanced mechanical protection and EMI shielding
• Phosphor bronze contact material with gold mating finish
• 767 units currently in stock

104068-1 (TE Connectivity Substitute):

• Active production status within AMPMODU System 50 series
• Not RoHS3 compliant; verify regulatory requirements before selection
• Operating temperature range -65°C to 105°C; lower upper limit than primary part
• 2-wall shrouding design; reduced mechanical protection compared to primary part
• Tin-lead post finish; verify compatibility with lead-free soldering processes
• 2250 units in stock; higher availability
• Suitable for general purpose, automotive, medical, and telecommunications applications

5-104068-1 (TE Connectivity Substitute):

• Active production status within AMPMODU System 50 series
• ROHS3 compliant; equivalent regulatory compliance to primary part
• Operating temperature range -65°C to 105°C; lower upper limit than primary part
• 2-wall shrouding design; reduced mechanical protection compared to primary part
• Tin post finish; compatible with lead-free soldering processes
• 2200 units in stock; high availability
• Suitable for general purpose, automotive, medical, and telecommunications applications

Selection between primary and substitute parts should be based on: (1) regulatory compliance requirements (RoHS status), (2) operating temperature envelope requirements, (3) mechanical protection and shrouding requirements, (4) supply chain and inventory availability, and (5) soldering process compatibility (lead-free vs. lead-containing finishes).

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 104068-1 or 5-104068-1 be used as a direct replacement for the Samtec TML-110-01-G-D?

A: Yes, both TE Connectivity parts meet the critical mating interface parameters: 0.050" (1.27mm) pitch, 20 positions in 2 rows, 0.100" (2.54mm) row spacing, through-hole solder termination, and male pin contact type. Mechanical and electrical compatibility is established for board-to-board applications. Secondary parameter differences (shrouding design, contact finish, insulation material) do not affect the core mating function.

Q: What are the key differences between the two TE Connectivity substitute parts?

A: The primary difference is RoHS compliance status. Part 5-104068-1 is ROHS3 compliant, while 104068-1 is not applicable for RoHS. Both parts share identical mating interface specifications, contact finish on the mating surface (gold), and operating temperature range (-65°C to 105°C). The post finish differs: 104068-1 uses tin-lead, while 5-104068-1 uses tin. Select 5-104068-1 for applications requiring RoHS3 compliance.

Q: Why does the Samtec TML-110-01-G-D have a higher operating temperature maximum (-55°C to 125°C) compared to the TE Connectivity substitutes (-65°C to 105°C)?

A: Operating temperature range is determined by insulation material properties and contact design. The Samtec part uses Liquid Crystal Polymer (LCP) insulation, while TE Connectivity parts use thermoplastic insulation. These material differences result in different thermal performance characteristics. For applications requiring operation above 105°C, the primary Samtec part is required.

Q: Are there packaging differences between the primary part and substitutes?

A: Yes. The Samtec TML-110-01-G-D is supplied in bulk packaging, while both TE Connectivity substitutes (104068-1 and 5-104068-1) are supplied in tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What is the significance of the 4-wall vs. 2-wall shrouding difference?

A: Shrouding design affects mechanical protection and EMI shielding. The Samtec TML-110-01-G-D features 4-wall shrouding, providing enhanced protection on all sides. The TE Connectivity substitutes feature 2-wall shrouding, providing reduced mechanical protection. For applications requiring maximum mechanical robustness or EMI shielding, the primary Samtec part is preferred.

Q: Can I use the TE Connectivity parts in lead-free soldering processes?

A: Part 5-104068-1 with tin post finish is compatible with lead-free soldering processes. Part 104068-1 with tin-lead post finish requires verification of your specific lead-free soldering parameters, as tin-lead finishes may require process adjustment. Consult your assembly process documentation.

Q: What is the fastening type difference between the primary part and substitutes?

A: The Samtec TML-110-01-G-D uses push-pull fastening, while both TE Connectivity substitutes use latch holder fastening. These are different mechanical retention mechanisms. Verify that your mating connector is compatible with the fastening type of your selected part.
