Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TML-140-01-G-D is determined by the following critical parameters that must match or be compatible:

Core Matching Parameters:

• Pitch - Mating: 0.050" (1.27mm)
• Number of Positions: 80
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Style: Board to Board

Acceptable Variation Parameters:

• Shrouding configuration (4 Wall vs. 2 Wall)
• Contact shape (Square vs. Circular)
• Contact finish composition (Gold vs. Gold/Tin-Lead vs. Gold/Tin)
• Insulation material (LCP vs. Thermoplastic)
• Fastening type (Push-Pull vs. Latch Holder)
• Packaging format (Bulk vs. Tube)

The substitute parts 1-104068-6 and 6-104068-6 (TE Connectivity AMP Connectors, AMPMODU System 50 series) meet all core matching parameters and are therefore electrically and mechanically compatible with the TML-140-01-G-D for board-to-board interconnection applications.

Parameter Comparison

Engineering Selection Recommendations

TML-140-01-G-D (Samtec Inc.):

• Primary selection for applications requiring 4-wall shrouding and push-pull fastening mechanism
• Supports extended operating temperature range (-55°C to 125°C)
• ROHS3 compliant
• Bulk packaging suitable for high-volume manufacturing
• Square contact geometry

1-104068-6 (TE Connectivity AMP Connectors):

• Alternative selection with 2-wall shrouding and latch holder fastening
• Supports extended lower temperature range (-65°C minimum)
• Voltage rating specified at 30VAC
• Tube packaging format
• Circular contact geometry
• RoHS status not applicable; verify compliance requirements for specific applications
• Suitable for automotive, general purpose, medical, and telecommunications applications

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

• Functionally equivalent to 1-104068-6 with identical electrical and mechanical specifications
• ROHS3 compliant
• Highest inventory availability (2272 pieces)
• Tube packaging format
• Circular contact geometry
• Recommended for supply chain continuity and rapid procurement scenarios

All three parts are active products suitable for direct substitution in board-to-board interconnection designs where the specified parameter variations are acceptable.

Frequently Asked Questions (FAQ)

Q: Can 1-104068-6 or 6-104068-6 be used as direct replacements for TML-140-01-G-D?

A: Yes. Both TE Connectivity parts are electrically and mechanically compatible. They share identical pitch (0.050"), position count (80), row configuration (2 rows at 0.100" spacing), connector type (header), contact type (male pin), mounting method (through hole), and termination (solder). Differences in shrouding (2-wall vs. 4-wall), fastening mechanism (latch holder vs. push-pull), and contact shape (circular vs. square) do not prevent functional substitution in board-to-board applications.

Q: What are the key differences between the TML-140-01-G-D and the TE Connectivity substitutes?

A: Primary differences include: (1) Shrouding configuration—TML-140-01-G-D features 4-wall shrouding while 1-104068-6 and 6-104068-6 feature 2-wall shrouding; (2) Fastening type—TML-140-01-G-D uses push-pull while TE parts use latch holder; (3) Contact shape—TML-140-01-G-D has square contacts while TE parts have circular contacts; (4) Insulation material—TML-140-01-G-D uses LCP while TE parts use thermoplastic; (5) Operating temperature range—TML-140-01-G-D operates -55°C to 125°C while TE parts operate -65°C to 105°C; (6) Contact post finish—TML-140-01-G-D uses gold while TE parts use tin-lead (1-104068-6) or tin (6-104068-6).

Q: Are there packaging format differences?

A: Yes. TML-140-01-G-D is supplied in bulk packaging, while both 1-104068-6 and 6-104068-6 are supplied in tube packaging. Tube packaging may require different handling and storage procedures in manufacturing environments.

Q: Which substitute part should be selected for maximum inventory availability?

A: Part 6-104068-6 has the highest inventory level at 2272 pieces, compared to 860 pieces for 1-104068-6 and 697 pieces for TML-140-01-G-D. Selection of 6-104068-6 supports rapid procurement and supply chain continuity.

Q: Is RoHS compliance a differentiator between these parts?

A: Yes. TML-140-01-G-D and 6-104068-6 are both ROHS3 compliant. Part 1-104068-6 has RoHS status listed as "not applicable." For applications requiring RoHS3 compliance, select either TML-140-01-G-D or 6-104068-6.

Q: What is the operating temperature consideration for substitution?

A: TML-140-01-G-D supports -55°C to 125°C operation. Both TE Connectivity substitutes support -65°C to 105°C operation. Applications requiring temperatures above 105°C must use TML-140-01-G-D. Applications operating below -55°C can use either TE part.

Q: Are the contact materials equivalent?

A: Contact materials differ: TML-140-01-G-D uses phosphor bronze while both TE parts use copper alloy. Both materials are suitable for solder termination and board-to-board interconnection. Contact finish on the mating surface is gold for all three parts, ensuring compatible signal integrity.
