Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TML-140-01-S-D is determined by the following critical parameters:

Primary Matching Criteria:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 80
• 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

Secondary Compatibility Factors:

• Contact Finish - Mating: Gold plating
• Insulation Material: LCP or equivalent thermoplastic
• Operating Temperature Range: Minimum -55°C, Maximum 125°C
• RoHS Compliance: ROHS3 Compliant

The substitute parts TE Connectivity 1-104068-6 and 6-104068-6 meet all primary matching criteria. Both are 80-position, 0.050" pitch headers with 2-row configuration, through-hole solder termination, and board-to-board style. Differences in shrouding design (4-wall vs. 2-wall), contact shape (square vs. circular), and fastening mechanism (push-pull vs. latch holder) represent acceptable variations within the rectangular connector header category.

Parameter Comparison

Engineering Selection Recommendations

TML-140-01-S-D (Primary Part): The Samtec TML-140-01-S-D is ROHS3 compliant and maintains an active product status with adequate inventory. This part features 4-wall shrouding and square contact geometry, providing enhanced mechanical stability and EMI shielding. The operating temperature range of -55°C to 125°C supports extended environmental applications. Selection of this part is appropriate for designs requiring maximum shrouding protection and the specific mechanical characteristics of square contacts.

1-104068-6 (TE Connectivity Substitute): The TE Connectivity 1-104068-6 matches all critical electrical and mechanical parameters for 80-position 0.050" pitch header applications. This part operates across -65°C to 105°C and carries a 30VAC voltage rating specification. The 2-wall shrouding design and circular contact geometry represent acceptable alternatives for applications where the primary part is unavailable. RoHS compliance status is listed as not applicable; designs requiring ROHS3 certification should reference the 6-104068-6 variant. Inventory availability is 860 pieces.

6-104068-6 (TE Connectivity Substitute - Preferred Alternative): The TE Connectivity 6-104068-6 is ROHS3 compliant and represents the preferred substitute when the TML-140-01-S-D is unavailable. This part maintains identical electrical and mechanical specifications to the 1-104068-6 while providing explicit ROHS3 compliance certification. Operating temperature range is -65°C to 105°C with 30VAC voltage rating. The 2-wall shrouding and circular contact design are functionally equivalent for board-to-board connector applications. Inventory availability is 2272 pieces, providing superior supply chain security.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-104068-6 and 6-104068-6 be used interchangeably with the Samtec TML-140-01-S-D?

A: Both TE Connectivity parts are functionally equivalent substitutes for the TML-140-01-S-D in applications requiring 80-position, 0.050" pitch, 2-row through-hole solder headers. All three parts share identical contact pitch, row spacing, number of positions, and mounting configuration. The primary differences are shrouding design (4-wall vs. 2-wall), contact shape (square vs. circular), and fastening mechanism (push-pull vs. latch holder). These differences do not affect electrical performance in standard board-to-board applications.

Q: What is the difference between the 1-104068-6 and 6-104068-6?

A: The 1-104068-6 and 6-104068-6 are mechanically and electrically identical. The primary distinction is RoHS compliance status: the 6-104068-6 is ROHS3 compliant, while the 1-104068-6 is listed as not applicable. For designs requiring ROHS3 certification, the 6-104068-6 is the appropriate selection. Both parts operate at -65°C to 105°C and carry 30VAC voltage ratings.

Q: Are there packaging differences between these parts?

A: Yes. The Samtec TML-140-01-S-D is supplied in bulk packaging, while both TE Connectivity parts (1-104068-6 and 6-104068-6) are supplied in tube packaging. Packaging format does not affect connector performance but may influence handling, storage, and assembly processes.

Q: What is the operating temperature difference between the TML-140-01-S-D and the TE Connectivity substitutes?

A: The TML-140-01-S-D operates from -55°C to 125°C, while the TE Connectivity 1-104068-6 and 6-104068-6 operate from -65°C to 105°C. The TE Connectivity parts provide lower minimum temperature capability (-65°C vs. -55°C) but lower maximum temperature capability (105°C vs. 125°C). Application temperature requirements must be evaluated against these ranges.

Q: Do the contact finish differences affect substitution?

A: All three parts feature gold-plated mating contacts with 30.0µin (0.76µm) thickness, ensuring equivalent electrical contact performance. Post finishes differ: the TML-140-01-S-D uses tin, while the 1-104068-6 uses tin-lead and the 6-104068-6 uses tin. These post finish variations do not affect mating performance and are acceptable substitutions for solder termination applications.

Q: What does the 2-wall vs. 4-wall shrouding difference mean?

A: Shrouding refers to the plastic walls surrounding the connector contacts. The TML-140-01-S-D features 4-wall shrouding, providing complete enclosure on all sides. The TE Connectivity substitutes feature 2-wall shrouding, providing partial enclosure. Both designs provide adequate mechanical protection and keying for standard board-to-board applications. The 4-wall design offers enhanced EMI shielding and mechanical stability, while the 2-wall design reduces overall connector profile.

Q: Can I use these connectors for cable-to-board applications?

A: The TML-140-01-S-D is specified for board-to-board style applications. The TE Connectivity 1-104068-6 and 6-104068-6 are specified as board-to-board or cable style, indicating broader application flexibility. For cable-to-board applications, the TE Connectivity parts are the appropriate selection.
