Substitute Part Grouping Explanation

Substitution eligibility for the TML-136-01-G-D-RA is determined by strict alignment of the following critical parameters:

Primary Matching Criteria:

• Connector type: Header
• Contact type: Male pin
• Number of positions: 72
• Number of rows: 2
• Pitch - mating: 0.050" (1.27mm)
• Row spacing - mating: 0.100" (2.54mm)
• Mounting type: Through hole, right angle
• Termination: Solder
• Style: Board to board or board to board/cable

Secondary Compatibility Factors:

• Operating temperature range must encompass or match the application requirement
• Contact finish must be gold on mating surface
• RoHS3 compliance status
• Shrouding configuration (shrouded design)

The substitute part 1-104069-6 (TE Connectivity AMP Connectors) meets all primary matching criteria and maintains functional compatibility for standard board-to-board interconnect applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (TML-136-01-G-D-RA):

Select the TML-136-01-G-D-RA when the application requires:

• Operating temperatures up to 125°C
• 4-wall shrouded design for enhanced EMI shielding
• Push-pull fastening mechanism
• Phosphor bronze contact material with square contact geometry
• LCP insulation material
• Gold plating on both mating and post surfaces
• Exact mechanical envelope matching the original design

Substitute Part Selection (1-104069-6):

The 1-104069-6 serves as a functional substitute when:

• Operating temperature requirement does not exceed 105°C
• 2-wall shrouding is acceptable for the application
• Latch holder fastening mechanism is compatible with the system design
• Copper alloy contact material is acceptable
• Circular contact geometry is compatible with mating receptacles
• Thermoplastic insulation material meets application requirements
• Tin-lead post finish is acceptable
• The application can accommodate the 0.020" difference in post contact length and 0.080" difference in insulation height

Both parts maintain ROHS3 compliance and are suitable for board-to-board interconnect applications. The substitute part provides thicker gold plating on mating surfaces (30.0µin versus 10.0µin), which may provide enhanced durability in high-cycle mating applications.

Frequently Asked Questions (FAQ)

Q: Can the 1-104069-6 be used as a direct drop-in replacement for the TML-136-01-G-D-RA?

A: The 1-104069-6 is functionally compatible for board-to-board applications with matching pitch, row spacing, and position count. However, physical differences exist: the substitute has reduced shrouding (2-wall versus 4-wall), different contact geometry (circular versus square), and different insulation height (0.290" versus 0.370"). PCB layout and mating receptacle compatibility must be verified before substitution.

Q: What are the temperature operating range differences?

A: The TML-136-01-G-D-RA operates from -55°C to 125°C, while the 1-104069-6 operates from -65°C to 105°C. The substitute has a lower maximum operating temperature (20°C reduction). Applications requiring operation above 105°C must use the primary part.

Q: How do the contact materials differ?

A: The TML-136-01-G-D-RA uses phosphor bronze contacts with square geometry, while the 1-104069-6 uses copper alloy contacts with circular geometry. Both materials are suitable for general interconnect applications. Contact geometry differences may affect mating force and receptacle compatibility.

Q: What is the significance of the shrouding difference?

A: The TML-136-01-G-D-RA features 4-wall shrouding, providing enhanced EMI shielding and mechanical protection. The 1-104069-6 has 2-wall shrouding, reducing shielding effectiveness but potentially allowing for different board layout configurations. Applications requiring high EMI immunity should use the primary part.

Q: Are there differences in the fastening mechanisms?

A: Yes. The TML-136-01-G-D-RA uses a push-pull fastening type, while the 1-104069-6 uses a latch holder mechanism. These are functionally different connection methods. System design must accommodate the specific fastening type of the selected connector.

Q: How do the contact post lengths differ?

A: The TML-136-01-G-D-RA has a 0.120" (3.05mm) post contact length, while the 1-104069-6 has a 0.100" (2.54mm) post contact length. This 0.020" difference affects solder joint geometry and PCB pad design. PCB layout verification is required before substitution.

Q: What is the difference in gold plating thickness?

A: The TML-136-01-G-D-RA has 10.0µin (0.25µm) gold plating on mating contacts, while the 1-104069-6 has 30.0µin (0.76µm). The thicker plating on the substitute may provide improved durability in high-cycle mating applications and enhanced corrosion resistance.

Q: Are both parts RoHS3 compliant?

A: Yes, both the TML-136-01-G-D-RA and 1-104069-6 are ROHS3 compliant and suitable for applications requiring RoHS compliance.

Q: What is the inventory status for each part?

A: The TML-136-01-G-D-RA has 910 units in stock. The 1-104069-6 has 1144 units in stock. Both parts are available as new original components.
