TML-136-01-T-D-RA Equivalent & Substitute Parts

Part Overview

The TML-136-01-T-D-RA is a shrouded rectangular connector header manufactured by Samtec Inc., designed for through-hole, right-angle board-to-board applications. This 72-position connector operates across the temperature range of -55°C to 105°C and features a 0.050" (1.27mm) pitch with 0.100" (2.54mm) row spacing. The part is currently in active production status with 949 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the core mating specifications, allowing for component interchangeability in applications where the primary part is unavailable or when design requirements permit alternative contact geometries or shrouding configurations.

Substitute Part Grouping Explanation

Substitution eligibility for the TML-136-01-T-D-RA is determined by strict alignment of the following core mating parameters:

• Pitch - Mating: 0.050" (1.27mm) — must match exactly for PCB footprint compatibility
• Number of Positions: 72 — must match for signal routing and connector density
• Number of Rows: 2 — must match for row configuration
• Row Spacing - Mating: 0.100" (2.54mm) — must match for mating interface geometry
• Connector Type: Header — must match for board-to-board application
• Contact Type: Male Pin — must match for mating polarity
• Mounting Type: Through Hole, Right Angle — must match for PCB assembly orientation
• Termination: Solder — must match for assembly process compatibility

The substitute part 1-104069-6 (TE Connectivity AMP Connectors) satisfies all core mating parameters. Variations in secondary parameters such as shrouding configuration (4 Wall vs. 2 Wall), contact finish (Tin vs. Gold), insulation material (LCP vs. Thermoplastic), and fastening type (Push-Pull vs. Latch Holder) do not preclude substitution when the primary mating interface specifications are equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the TML-136-01-T-D-RA and 1-104069-6 are active production components with ROHS3 compliance and EAR99 export classification. Selection between these parts should be based on the following engineering criteria:

TML-136-01-T-D-RA (Samtec Inc.) is the primary specification when:

• 4-wall shrouding is required for enhanced EMI shielding or mechanical protection
• Tin contact finish is specified for cost optimization or specific soldering processes
• Liquid Crystal Polymer (LCP) insulation material is required for dimensional stability or chemical resistance
• Push-Pull fastening mechanism is preferred for the mating interface
• The operating temperature minimum of -55°C is sufficient for the application

1-104069-6 (TE Connectivity AMP Connectors) is an acceptable substitute when:

• 2-wall shrouding meets application requirements
• Gold contact finish is acceptable or preferred for enhanced corrosion resistance and contact reliability
• Thermoplastic insulation material is compatible with the application environment
• Latch Holder fastening mechanism is acceptable for the mating interface
• The extended operating temperature minimum of -65°C provides additional margin
• Voltage rating of 30VAC is applicable to the circuit design

Both parts support board-to-board applications with identical mating pitch, position count, and row spacing. PCB footprint compatibility is maintained between these two connectors for the mating interface.

Frequently Asked Questions (FAQ)

Q: Can the 1-104069-6 be used as a direct replacement for the TML-136-01-T-D-RA on existing PCBs?

A: Yes, the 1-104069-6 is compatible with PCBs designed for the TML-136-01-T-D-RA. Both connectors share identical mating pitch (0.050"), position count (72), row configuration (2 rows), and row spacing (0.100"). The through-hole, right-angle mounting footprint is equivalent. However, the mating connector must be compatible with the 2-wall shrouding and Latch Holder fastening mechanism of the 1-104069-6.

Q: What are the differences in shrouding between these two parts?

A: The TML-136-01-T-D-RA features 4-wall shrouding, which provides complete perimeter protection around the connector body. The 1-104069-6 features 2-wall shrouding, which provides protection on two opposing sides. The 4-wall design offers greater mechanical protection and EMI shielding, while the 2-wall design reduces overall connector profile and cost.

Q: Are the contact finishes interchangeable?

A: The TML-136-01-T-D-RA uses tin contact finish on the mating interface, while the 1-104069-6 uses gold (30.0µin thickness). Gold provides superior corrosion resistance and contact reliability in harsh environments. Tin is suitable for standard applications and offers cost advantages. The choice depends on environmental conditions and reliability requirements of the specific application.

Q: What is the impact of different insulation materials?

A: The TML-136-01-T-D-RA uses Liquid Crystal Polymer (LCP) insulation, which provides excellent dimensional stability and chemical resistance. The 1-104069-6 uses Thermoplastic insulation. Both materials are suitable for standard board-to-board applications. LCP offers superior performance in high-temperature or chemically aggressive environments, while Thermoplastic is cost-effective for general-purpose applications.

Q: Do these connectors have different operating temperature ranges?

A: The TML-136-01-T-D-RA operates from -55°C to 105°C. The 1-104069-6 operates from -65°C to 105°C. The 1-104069-6 provides an additional 10°C margin at the lower temperature limit, which may be beneficial for applications requiring extended cold-temperature performance.

Q: What is the difference in fastening mechanisms?

A: The TML-136-01-T-D-RA uses a Push-Pull fastening type, while the 1-104069-6 uses a Latch Holder fastening type. Push-Pull mechanisms provide quick-connect/disconnect capability with tactile feedback. Latch Holder mechanisms provide secure retention with positive locking. The choice depends on whether the application requires frequent mating/unmating or permanent installation.

Q: Are both parts RoHS compliant?

A: Yes, both the TML-136-01-T-D-RA and 1-104069-6 are ROHS3 compliant, meeting the Restriction of Hazardous Substances directive requirements for lead-free manufacturing and restricted substance limits.
