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

Part Overview

The TML-134-01-G-D is a shrouded rectangular connector header manufactured by Samtec Inc., designed for through-hole 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 features male pins with gold-plated phosphor bronze contacts, liquid crystal polymer insulation, and push-pull fastening. The product maintains active status and is ROHS3 compliant, with 716 units currently in stock.

Identifying equivalent and substitute parts is necessary when the primary part is unavailable, when alternative packaging formats are required, or when design flexibility permits component optimization within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TML-134-01-G-D is determined by strict adherence to the following critical parameters:

Primary Matching Criteria:

• Connector type: Header
• Contact type: Male pin
• Number of positions: 68
• Number of rows: 2
• Pitch - mating: 0.050" (1.27mm)
• Row spacing - mating: 0.100" (2.54mm)
• Mounting type: Through hole
• Termination: Solder

Secondary Compatibility Parameters:

• Shrouding configuration (must be shrouded)
• Contact finish: Gold plating on mating surface
• Insulation material compatibility
• Operating temperature range overlap
• RoHS compliance status

The substitute part 6-104068-8 (TE Connectivity AMP Connectors) satisfies all primary matching criteria and maintains compatibility across secondary parameters, though with documented variations in shrouding wall count, contact geometry, and fastening mechanism.

Engineering Selection Recommendations

TML-134-01-G-D Selection Criteria:

• Primary choice when 4-wall shrouding is required for enhanced EMI shielding or mechanical protection
• Preferred when push-pull fastening mechanism is specified in design requirements
• Suitable for applications requiring operating temperatures up to 125°C
• Recommended when liquid crystal polymer insulation material is mandated by design specifications
• Select when square contact geometry is required for specific mating interface designs

6-104068-8 Selection Criteria:

• Acceptable substitute when 2-wall shrouding meets mechanical and electrical requirements
• Suitable when latch holder fastening mechanism is compatible with application design
• Appropriate for applications with maximum operating temperature of 105°C
• Viable when thermoplastic insulation material is acceptable
• Select when circular contact geometry is compatible with mating connector design
• Applicable when 30VAC voltage rating specification is satisfied

Both parts maintain ROHS3 compliance and share identical pitch, row spacing, and position count. Selection between these parts depends on specific design requirements regarding shrouding configuration, fastening mechanism, temperature range, and contact geometry.

Frequently Asked Questions (FAQ)

Q: Can the 6-104068-8 directly replace the TML-134-01-G-D in existing designs?

A: Direct replacement requires verification of three design-critical parameters: (1) fastening mechanism compatibility (push-pull versus latch holder), (2) operating temperature range requirements (125°C maximum for TML-134-01-G-D versus 105°C for 6-104068-8), and (3) shrouding wall count adequacy (4-wall versus 2-wall). Mechanical fit and electrical performance are compatible when these parameters align with application requirements.

Q: What are the key differences in contact specifications?

A: The TML-134-01-G-D features square phosphor bronze contacts with 10.0µin gold plating thickness, while the 6-104068-8 uses circular copper alloy contacts with 30.0µin gold plating thickness. Mating contact length differs by 0.005" (0.13mm), and post contact length differs by 0.005" (0.13mm). These variations affect mating force, contact resistance, and durability characteristics.

Q: Are packaging differences significant for component selection?

A: The TML-134-01-G-D is supplied in bulk packaging, while the 6-104068-8 is supplied in tube packaging. Packaging format affects handling, storage, and automated assembly compatibility but does not impact electrical or mechanical performance of the connector itself.

Q: What is the significance of the shrouding wall count difference?

A: The TML-134-01-G-D provides 4-wall shrouding, offering enhanced mechanical protection and EMI shielding compared to the 2-wall shrouding of the 6-104068-8. Applications requiring maximum electromagnetic interference rejection or robust mechanical protection should specify the 4-wall configuration.

Q: How do the fastening mechanisms differ functionally?

A: The TML-134-01-G-D uses push-pull fastening, requiring axial force application for mating and unmating. The 6-104068-8 uses latch holder fastening, which typically provides positive mechanical retention through latching features. Fastening mechanism selection depends on application requirements for connection security and maintenance accessibility.

Q: Are both parts suitable for the same temperature range applications?

A: No. The TML-134-01-G-D operates from -55°C to 125°C, while the 6-104068-8 operates from -65°C to 105°C. Applications requiring operation above 105°C must use the TML-134-01-G-D. Applications requiring operation below -55°C must use the 6-104068-8.

Q: What is the impact of different insulation materials?

A: The TML-134-01-G-D uses liquid crystal polymer (LCP) insulation, offering superior dimensional stability and chemical resistance. The 6-104068-8 uses thermoplastic insulation, which provides adequate performance for general applications but may exhibit greater dimensional variation under thermal cycling. Material selection depends on environmental exposure and precision requirements.
