Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TML-113-03-G-D is determined by strict alignment of the following critical parameters:

Primary Compatibility Criteria:

• Connector type: Header
• Contact type: Male Pin
• Number of positions: 26
• Number of rows: 2
• Pitch - mating: 0.050" (1.27mm)
• Row spacing - mating: 0.100" (2.54mm)
• Mounting type: Through Hole
• Termination: Solder
• Style: Board to Board or Board to Board/Cable

Secondary Compatibility Criteria:

• Shrouding: Shrouded configuration
• Contact finish - mating: Gold plating
• Insulation color: Black
• Product status: Active

The substitute parts identified (1-104068-2 and 6-104068-2) from TE Connectivity AMP Connectors meet all primary compatibility criteria. Both parts are manufactured under the AMPMODU System 50 series and maintain functional equivalence for through-hole solder termination applications with identical pitch and position specifications.

Engineering Selection Recommendations

TML-113-03-G-D (Samtec Inc.):

• Primary selection for applications requiring ROHS3 compliance
• Suitable for extended temperature range applications (-55°C to 125°C)
• 4-wall shrouding provides enhanced EMI shielding
• Gold-plated phosphor bronze contacts with minimal finish thickness
• Active product status with established supply chain

1-104068-2 (TE Connectivity AMP Connectors):

• Alternative for applications where RoHS compliance is not required
• Operates within -65°C to 105°C range
• 2-wall shrouding configuration
• Tin-lead post finish on copper alloy contacts
• Active product status with 858 units available
• Supports both board-to-board and cable applications

6-104068-2 (TE Connectivity AMP Connectors):

• Preferred TE Connectivity substitute with RoHS compliance
• Operates within -65°C to 105°C range
• 2-wall shrouding configuration
• Tin post finish on copper alloy contacts
• Active product status with highest inventory availability (1045 units)
• Supports both board-to-board and cable applications

Selection between substitute parts should be based on compliance requirements, operating temperature specifications, and application flexibility. The 6-104068-2 offers the highest inventory availability and RoHS compliance alignment with the primary part.

Frequently Asked Questions (FAQ)

Q: Can 1-104068-2 and 6-104068-2 be used interchangeably with TML-113-03-G-D?

A: Both TE Connectivity parts share identical pitch (0.050"), position count (26), row configuration (2 rows), and mounting specifications (through-hole solder termination). They are functionally compatible for board-to-board connector applications. However, differences in contact geometry (circular vs. square), shrouding design (2-wall vs. 4-wall), and operating temperature ranges must be evaluated against specific application requirements.

Q: What are the differences between 1-104068-2 and 6-104068-2?

A: Both parts are identical in electrical and mechanical specifications. The primary difference is the contact finish on the post: 1-104068-2 uses tin-lead finish while 6-104068-2 uses tin finish. Additionally, 1-104068-2 has "Not applicable" RoHS status while 6-104068-2 is RoHS Compliant. The 6-104068-2 is recommended for new designs requiring RoHS compliance.

Q: Does the operating temperature difference affect substitution?

A: The TML-113-03-G-D operates from -55°C to 125°C, while both TE Connectivity substitutes operate from -65°C to 105°C. Applications requiring temperatures above 105°C must use the TML-113-03-G-D. Applications within the -55°C to 105°C range can use either part.

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

A: The TML-113-03-G-D features 4-wall shrouding, providing enhanced electromagnetic interference (EMI) shielding and mechanical protection. The TE Connectivity substitutes feature 2-wall shrouding. Applications requiring maximum EMI protection should specify the TML-113-03-G-D.

Q: Are there packaging differences between these parts?

A: Yes. The TML-113-03-G-D is supplied in bulk packaging, while both TE Connectivity substitutes are supplied in tube packaging. Tube packaging may be preferred for automated assembly processes.

Q: Which part should be selected for new product designs?

A: For new designs requiring RoHS compliance and extended temperature operation, the TML-113-03-G-D is recommended. For designs where RoHS compliance is required but operating temperature does not exceed 105°C, the 6-104068-2 offers equivalent functionality with higher inventory availability.

Q: What is the contact finish thickness significance?

A: The TML-113-03-G-D has 10.0µin (0.25µm) gold mating finish, while TE Connectivity substitutes have 30.0µin (0.76µm) gold mating finish. The thicker gold plating on substitute parts provides enhanced wear resistance and corrosion protection in high-cycle mating applications.
