Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TML-108-03-G-D is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 16
• Number of Rows: 2
• Pitch - Mating: 0.050" (1.27mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder

Allowable Variation Parameters:

• Shrouding configuration (4-wall vs. 2-wall designs)
• Contact shape (square vs. circular)
• Contact finish composition and thickness
• Insulation material type (LCP vs. thermoplastic)
• Fastening mechanism (push-pull vs. latch holder)
• Contact length specifications within functional tolerance
• Insulation height within manufacturing tolerance

The substitute part 6-104068-0 (TE Connectivity AMP Connectors) meets all mandatory matching parameters and operates within allowable variation ranges for board-to-board connector applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (TML-108-03-G-D): Select the TML-108-03-G-D when the application requires operation across the full temperature range of -55°C to 125°C. This part is suitable for industrial and military-grade applications demanding extended thermal performance. The 4-wall shrouding provides enhanced EMI shielding and mechanical protection. ROHS3 compliance and EAR99 classification support global distribution.

Substitute Part Selection (6-104068-0): The 6-104068-0 serves as a functional equivalent for applications operating within the -65°C to 105°C temperature range. This part is suitable for automotive, medical, telecommunications, and general-purpose applications. The 2-wall shrouding reduces overall connector profile while maintaining electrical integrity. The latch holder fastening mechanism provides positive retention. ROHS3 compliance and UL94 V-0 flammability rating support regulated industry applications. The 30VAC voltage rating specification provides additional design documentation for power distribution circuits.

Compatibility Considerations: Both parts maintain identical mating pitch (0.050"), row spacing (0.100"), position count (16), and row configuration (2). Mechanical footprint compatibility is confirmed for PCB layout purposes. The substitute part's 2-wall shrouding versus 4-wall design may affect connector profile and EMI performance in sensitive applications. Contact length variations (0.170" vs. 0.125" mating contact) require verification against mating receptacle specifications. Operating temperature range differences necessitate thermal analysis for applications approaching -55°C or exceeding 105°C.

Frequently Asked Questions (FAQ)

Q: Can the 6-104068-0 directly replace the TML-108-03-G-D in all applications?

A: Direct replacement is possible when the application operates within the 6-104068-0 temperature range (-65°C to 105°C) and does not require the extended high-temperature capability of the TML-108-03-G-D (-55°C to 125°C). The 2-wall shrouding of the substitute part may affect EMI performance compared to the 4-wall design. Mating receptacle compatibility must be verified based on contact length specifications.

Q: What are the key differences in contact finish between these parts?

A: The TML-108-03-G-D features gold plating on both mating contacts (10.0µin) and posts (flash thickness). The 6-104068-0 provides thicker gold plating on mating contacts (30.0µin) but uses tin plating on posts (150.0µin). Both finishes support solder termination and provide corrosion resistance. The thicker gold on the substitute part's mating contacts may provide enhanced wear resistance in high-cycle mating applications.

Q: Are there packaging differences that affect procurement?

A: The TML-108-03-G-D is supplied in bulk packaging, while the 6-104068-0 is supplied in tube packaging. Bulk packaging typically supports higher-volume manufacturing environments, while tube packaging provides individual part protection for lower-volume or kit-based applications. Inventory availability differs: 964 units for the primary part versus 756 units for the substitute.

Q: How do the shrouding configurations affect connector performance?

A: The TML-108-03-G-D features 4-wall shrouding, which provides complete perimeter protection and enhanced EMI shielding. The 6-104068-0 features 2-wall shrouding, reducing overall connector height and profile while maintaining electrical isolation between adjacent contacts. Applications requiring maximum EMI rejection should specify the 4-wall design. Space-constrained designs may benefit from the 2-wall configuration.

Q: What fastening mechanism differences exist between these parts?

A: The TML-108-03-G-D uses push-pull fastening, providing quick-disconnect capability with positive engagement feedback. The 6-104068-0 uses a latch holder mechanism, offering positive retention through mechanical latching. Push-pull fastening supports frequent mating cycles and field serviceability. Latch holder fastening provides permanent connection security in fixed installations.

Q: Are both parts suitable for automotive applications?

A: The 6-104068-0 is explicitly rated for automotive applications and includes UL94 V-0 flammability certification. The TML-108-03-G-D does not specify automotive qualification in the provided documentation. For automotive applications, the 6-104068-0 is the appropriate selection when temperature requirements fall within its operating range.

Q: What is the significance of the voltage rating specification?

A: The 6-104068-0 specifies a 30VAC voltage rating, providing documented electrical performance for AC power distribution circuits. The TML-108-03-G-D does not include a voltage rating specification in the provided data. For applications requiring voltage rating documentation, the 6-104068-0 provides explicit electrical performance parameters.
