Substitute Part Grouping Explanation

Substitute parts for the TML-117-03-G-D are identified based on strict alignment of the following critical parameters:

Core Compatibility Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 34
• 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

The substitute parts identified (TE Connectivity AMP Connectors 1-104068-3 and 6-104068-3) satisfy all core compatibility parameters. Both parts are from the AMPMODU System 50 series and maintain the same 34-position, 2-row configuration with identical pitch and row spacing specifications. All substitute parts are Active product status with confirmed inventory availability.

Parameter Comparison

Engineering Selection Recommendations

TML-117-03-G-D (Primary Part): The TML-117-03-G-D is ROHS3 compliant and operates across an extended temperature range (-55°C ~ 125°C). This part features 4-wall shrouding and gold-plated contacts on both mating and post surfaces. Select this part when RoHS3 compliance is mandatory and extended temperature performance is required.

6-104068-3 (Preferred Substitute): The TE Connectivity 6-104068-3 is ROHS3 compliant and maintains Active product status. This part is functionally equivalent for board-to-board applications and offers the highest inventory availability (2250 pcs). The operating temperature range (-65°C ~ 105°C) is suitable for most general-purpose applications. Select this part when RoHS3 compliance is required and supply chain flexibility is prioritized.

1-104068-3 (Alternative Substitute): The TE Connectivity 1-104068-3 is RoHS non-compliant and should be selected only when RoHS compliance is not a design requirement. This part is suitable for legacy systems or applications where RoHS exemptions apply. Inventory availability is adequate (1184 pcs).

Compliance Considerations:

• For new designs requiring RoHS3 compliance: Select TML-117-03-G-D or 6-104068-3
• For legacy or non-regulated applications: 1-104068-3 is acceptable
• All three parts are Active product status with confirmed availability

Mechanical Compatibility Notes: All three parts maintain identical pitch (0.050"), row spacing (0.100"), and position count (34 positions, 2 rows). PCB footprints are compatible. Differences in shrouding design (4-wall vs. 2-wall), contact shape (square vs. circular), and contact length may require mechanical verification in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Are the TML-117-03-G-D and TE Connectivity 6-104068-3 electrically interchangeable?

A: Yes. Both parts share identical core electrical specifications: 34-position, 2-row configuration with 0.050" (1.27mm) pitch mating contacts and 0.100" (2.54mm) row spacing. Both are through-hole solder-terminated headers with gold-plated mating contacts. Electrical performance is equivalent for board-to-board applications.

Q: What are the key differences between the substitute parts?

A: The primary differences are: (1) RoHS compliance status—6-104068-3 is ROHS3 compliant while 1-104068-3 is not; (2) Contact finish on posts—6-104068-3 uses tin while 1-104068-3 uses tin-lead; (3) Insulation material—TML-117-03-G-D uses LCP while TE Connectivity parts use thermoplastic; (4) Shrouding design—TML-117-03-G-D has 4-wall shrouding while TE Connectivity parts have 2-wall shrouding; (5) Operating temperature range—TML-117-03-G-D operates to -55°C while TE Connectivity parts operate to -65°C.

Q: Can I use the TE Connectivity parts as direct drop-in replacements?

A: Yes, for standard board-to-board applications. The identical pitch, row spacing, and position count ensure PCB footprint compatibility. However, verify mechanical clearance due to differences in shrouding design (4-wall vs. 2-wall) and contact length specifications in space-constrained layouts.

Q: Which substitute part should I select for new designs?

A: For new designs, select 6-104068-3 if RoHS3 compliance is required. This part is ROHS3 compliant, Active product status, and offers the highest inventory availability (2250 pcs). The operating temperature range (-65°C ~ 105°C) is suitable for general-purpose applications.

Q: What is the difference between 1-104068-3 and 6-104068-3?

A: Both parts are from the same AMPMODU System 50 series with identical electrical and mechanical specifications. The primary difference is RoHS compliance: 6-104068-3 is ROHS3 compliant while 1-104068-3 is RoHS non-compliant. Additionally, 6-104068-3 has tin post finish while 1-104068-3 has tin-lead post finish. Select 6-104068-3 for RoHS-regulated applications.

Q: Are there packaging differences between these parts?

A: Yes. The TML-117-03-G-D is supplied in Bulk packaging, while both TE Connectivity substitute parts (1-104068-3 and 6-104068-3) are supplied in Tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What is the operating temperature range for each part?

A: TML-117-03-G-D operates from -55°C to 125°C. Both TE Connectivity parts (1-104068-3 and 6-104068-3) operate from -65°C to 105°C. The TML part provides extended high-temperature capability while the TE Connectivity parts provide extended low-temperature capability.

Q: Can these parts be used in automotive applications?

A: The TE Connectivity parts (1-104068-3 and 6-104068-3) list automotive applications in their specifications. The TML-117-03-G-D does not specify automotive applications. Verify application requirements and any automotive qualification standards before selection.
