TML-134-01-G-D-RA Equivalent & Substitute Parts

Part Overview

The TML-134-01-G-D-RA is a shrouded rectangular connector header manufactured by Samtec Inc., designed for through-hole, right-angle board-to-board applications. This 68-position connector operates at 0.050" (1.27mm) pitch with 2 rows spaced 0.100" (2.54mm) apart. The part is currently in active production status with 1071 pieces available in stock.

Identifying equivalent and substitute parts is necessary when the primary part is unavailable, when supply chain optimization is required, or when design flexibility permits component alternatives that meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TML-134-01-G-D-RA is permissible when the replacement part maintains the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 68
• 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, Right Angle
• Termination: Solder
• Style: Board to Board or Board to Board/Cable

Allowable Variations: Substitute parts may differ in shrouding design (wall count), contact length specifications, insulation material composition, contact finish thickness, fastening mechanism, and operating temperature range, provided the substitute part is rated for the intended application environment and maintains electrical continuity and mechanical fit.

The part 6-104069-8 (TE Connectivity AMP Connectors) qualifies as a substitute based on matching all mandatory parameters while differing in secondary characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The TML-134-01-G-D-RA remains the preferred choice when available. This part is in active production status with adequate inventory (1071 pieces in stock) and carries ROHS3 compliance certification.

Substitute Part Selection: The 6-104069-8 (TE Connectivity AMP Connectors) is an acceptable substitute when the TML-134-01-G-D-RA is unavailable. Both parts are active production items with equivalent inventory availability (1211 pieces in stock for the substitute).

Compliance Considerations: Both parts meet RoHS requirements. The TML-134-01-G-D-RA carries ROHS3 compliance, while the 6-104069-8 carries RoHS compliance. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Design Integration Factors: The substitute part differs in the following secondary characteristics that may require design verification:

• Shrouding configuration: 4-wall versus 2-wall design
• Fastening mechanism: Push-Pull versus Latch Holder
• Contact geometry: Square versus Circular contact shape
• Insulation height: 0.370" versus 0.290"
• Operating temperature upper limit: 125°C versus 105°C
• Post contact length: 0.120" versus 0.100"

These differences do not prevent substitution for board-to-board applications where the mating connector accommodates the alternative contact geometry and fastening mechanism.

Frequently Asked Questions (FAQ)

Q: Can the 6-104069-8 be used as a direct replacement for the TML-134-01-G-D-RA?

A: The 6-104069-8 is mechanically and electrically compatible for board-to-board applications. Both connectors share identical pitch (0.050"), row spacing (0.100"), position count (68), and row configuration (2 rows). However, the mating connector must accommodate the 2-wall shrouding and Latch Holder fastening mechanism of the substitute part, as opposed to the 4-wall shrouding and Push-Pull mechanism of the primary part.

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

A: Substitution requires matching of: number of positions (68), number of rows (2), mating pitch (0.050" / 1.27mm), row spacing (0.100" / 2.54mm), connector type (Header), contact type (Male Pin), mounting type (Through Hole, Right Angle), termination method (Solder), and style (Board to Board or Board to Board/Cable).

Q: Are there temperature rating differences between these parts?

A: Yes. The TML-134-01-G-D-RA operates from -55°C to 125°C, while the 6-104069-8 operates from -65°C to 105°C. The substitute part has a lower maximum operating temperature (105°C versus 125°C) but a lower minimum temperature rating (-65°C versus -55°C). Application requirements must be evaluated against these ranges.

Q: Do both parts have the same RoHS compliance status?

A: Both parts are RoHS compliant. The TML-134-01-G-D-RA carries ROHS3 compliance, while the 6-104069-8 carries RoHS compliance. Both meet regulatory requirements for lead-free manufacturing.

Q: What is the difference in shrouding between these connectors?

A: The TML-134-01-G-D-RA features 4-wall shrouding, providing complete perimeter protection. The 6-104069-8 features 2-wall shrouding, providing reduced perimeter coverage. The 4-wall design offers greater mechanical protection and EMI shielding characteristics.

Q: Can the fastening mechanisms be interchanged?

A: No. The TML-134-01-G-D-RA uses a Push-Pull fastening mechanism, while the 6-104069-8 uses a Latch Holder mechanism. The mating connector must be compatible with the fastening type of the selected header. These mechanisms are not interchangeable.

Q: Are the contact geometries compatible?

A: The TML-134-01-G-D-RA uses square contacts, while the 6-104069-8 uses circular contacts. The mating connector receptacle must be designed to accept the contact geometry of the selected header. Verify mating connector specifications before substitution.

Q: What is the inventory status for both parts?

A: The TML-134-01-G-D-RA has 1071 pieces in stock. The 6-104069-8 has 1211 pieces in stock. Both parts are available for immediate procurement.
