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

Part Overview

The TML-136-01-S-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 industrial temperature range of -55°C to 125°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 ROHS3 compliance certification.

Identifying equivalent and substitute parts is necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit mechanical or electrical parameter variations within acceptable tolerances for the application.

Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Matching Parameters:

• Pitch - Mating: 0.050" (1.27mm)
• Number of Positions: 72
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Product Status: Active

Allowable Variations:

• Shrouding configuration (4-wall vs. 2-wall)
• Contact shape (square vs. circular)
• Insulation material (LCP vs. thermoplastic)
• Insulation height
• Contact length specifications
• Fastening mechanism (push-pull vs. latch holder)
• Operating temperature range (provided minimum operating temperature is maintained)

The substitute part 1-104069-6 (TE Connectivity AMP Connectors) satisfies all mandatory matching parameters and is therefore classified as a direct functional equivalent for board-to-board connector applications requiring 72-position, 0.050" pitch headers with right-angle through-hole mounting.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (TML-136-01-S-D-RA): Select the TML-136-01-S-D-RA when the design requires the extended operating temperature range of -55°C to 125°C, 4-wall shrouding for enhanced EMI shielding, or when the push-pull fastening mechanism is specified. This part maintains active production status with ROHS3 compliance and is suitable for industrial and military-grade applications.

Substitute Part Selection (1-104069-6): The 1-104069-6 serves as a functional equivalent when supply availability of the primary part is constrained. This substitute maintains all critical electrical and mechanical parameters for board-to-board connectivity. However, the following design considerations apply:

• Operating temperature range is reduced to -65°C to 105°C; verify that the application maximum operating temperature does not exceed 105°C
• Shrouding is 2-wall instead of 4-wall; assess EMI shielding requirements for the application
• Insulation height is 0.290" versus 0.370"; confirm PCB layout and component clearance compatibility
• Contact post length is 0.100" versus 0.120"; verify solder joint formation on target PCB thickness
• Fastening mechanism is latch holder instead of push-pull; confirm mating connector compatibility

Both parts are ROHS3 compliant and maintain active production status, supporting long-term supply chain stability.

Frequently Asked Questions (FAQ)

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

A: The 1-104069-6 is functionally equivalent for 72-position, 0.050" pitch board-to-board connectivity. However, it is not a direct mechanical drop-in due to differences in insulation height (0.290" vs. 0.370"), contact post length (0.100" vs. 0.120"), and fastening mechanism (latch holder vs. push-pull). PCB layout and mating connector compatibility must be verified before substitution.

Q: What are the critical parameters that must match for substitution?

A: Substitution requires exact matching of: pitch (0.050"), position count (72), row configuration (2 rows), row spacing (0.100"), connector type (header), contact type (male pin), mounting style (through-hole right-angle), and termination method (solder). Variations in shrouding, contact shape, insulation material, and fastening mechanism are allowable if the application permits.

Q: Are both parts RoHS compliant?

A: Yes, both the TML-136-01-S-D-RA and 1-104069-6 are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing.

Q: What is the difference in operating temperature ranges?

A: The TML-136-01-S-D-RA operates from -55°C to 125°C, while the 1-104069-6 operates from -65°C to 105°C. If the application requires operation above 105°C, the TML-136-01-S-D-RA is the required selection. The substitute part has a lower maximum operating temperature limit.

Q: How do the shrouding configurations differ?

A: The TML-136-01-S-D-RA features 4-wall shrouding, providing enhanced electromagnetic interference (EMI) shielding and mechanical protection. The 1-104069-6 features 2-wall shrouding, which reduces overall connector profile but provides less EMI containment. Application EMI requirements determine which configuration is appropriate.

Q: What packaging format is used for both parts?

A: Both parts are supplied in tube packaging, suitable for automated assembly processes and manual component handling. Current inventory levels are 1012 pieces for the TML-136-01-S-D-RA and 1144 pieces for the 1-104069-6.

Q: Are there differences in contact finish specifications?

A: Both parts feature gold-plated mating contacts with 30.0µin (0.76µm) thickness. The post finish differs: the TML-136-01-S-D-RA uses tin plating, while the 1-104069-6 uses tin-lead plating. This difference affects solder joint formation characteristics during PCB assembly.
