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

Part Overview

The TML-134-01-S-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 dual-row configuration and 0.100" (2.54mm) row spacing. The component features gold-plated mating contacts, tin-plated posts, and phosphor bronze contact material with liquid crystal polymer insulation. The part maintains active product status and is ROHS3 compliant. Identifying equivalent substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate alternative sourcing when the primary part becomes unavailable or when design requirements necessitate alternative connector architectures.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TML-134-01-S-D is determined by strict alignment of critical electrical and mechanical parameters. The following parameters establish the substitution criteria:

Primary Matching Parameters:

• 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
• Style: Board to Board or Board to Board/Cable

Secondary Compatibility Parameters:

• Operating Temperature Range: Must encompass or match the specified range
• Contact Finish - Mating: Gold plating required
• Contact Finish - Post: Tin plating required
• Insulation Material: LCP or equivalent thermoplastic
• RoHS Compliance: ROHS3 Compliant

The substitute part 6-104068-8 (TE Connectivity AMP Connectors) satisfies all primary matching parameters and maintains compatibility across secondary parameters with documented variations in shrouding architecture (2-wall versus 4-wall), contact geometry (circular versus square), and fastening mechanism (latch holder versus push-pull).

Parameter Comparison

Engineering Selection Recommendations

Both the TML-134-01-S-D and 6-104068-8 maintain active product status and ROHS3 compliance, establishing baseline suitability for current design implementations. The TML-134-01-S-D operates across a wider temperature range (-55°C to 125°C) compared to the 6-104068-8 (-65°C to 105°C), with overlap occurring between -55°C and 105°C. Applications requiring operation below -55°C or above 105°C necessitate the TML-134-01-S-D.

The 6-104068-8 provides documented voltage rating specification (30VAC), whereas the TML-134-01-S-D does not specify voltage rating in available data. Both parts share identical pitch (0.050"), row spacing (0.100"), position count (68), and row configuration (2), ensuring mechanical interchangeability at the board interface level.

Documented variations include shrouding architecture (4-wall versus 2-wall), contact geometry (square versus circular), fastening mechanism (push-pull versus latch holder), and insulation material composition (LCP versus thermoplastic). These variations require evaluation against specific application requirements, PCB layout constraints, and mating connector specifications.

Frequently Asked Questions (FAQ)

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

A: Direct replacement requires verification of three factors: (1) operating temperature range compatibility within the overlap region (-55°C to 105°C), (2) PCB layout accommodation of dimensional variations in contact length and insulation height, and (3) mating connector compatibility with the 2-wall shrouding and circular contact geometry of the 6-104068-8.

Q: What are the key dimensional differences between these parts?

A: Contact length variations exist: TML-134-01-S-D mating contact is 0.120" (3.05mm) versus 6-104068-8 at 0.125" (3.18mm). Post length differs: 0.105" (2.67mm) versus 0.100" (2.54mm). Insulation height varies: 0.380" (9.65mm) versus 0.390" (9.91mm). These differences may affect PCB trace routing and component clearance.

Q: Are the contact materials equivalent?

A: Contact materials differ: TML-134-01-S-D uses phosphor bronze while 6-104068-8 uses copper alloy. Both materials support gold plating on mating surfaces and tin plating on post surfaces. Material selection impacts mechanical properties and long-term reliability characteristics.

Q: What is the significance of shrouding differences?

A: The TML-134-01-S-D features 4-wall shrouding providing enhanced EMI shielding and mechanical protection, while the 6-104068-8 provides 2-wall shrouding. This affects board-level EMI performance and mechanical robustness in high-vibration environments.

Q: How do fastening mechanisms differ?

A: The TML-134-01-S-D uses push-pull fastening for quick-disconnect applications, while the 6-104068-8 uses latch holder fastening. These mechanisms are not interchangeable and require different mating connector designs.

Q: What packaging differences exist?

A: TML-134-01-S-D is supplied in bulk packaging with 979 pieces in stock, while 6-104068-8 is supplied in tube packaging with 1850 pieces in stock. Packaging affects handling, storage, and automated assembly compatibility.

Q: Are both parts suitable for automotive applications?

A: The 6-104068-8 explicitly lists automotive applications in its specification. The TML-134-01-S-D does not specify applications in available data. Automotive qualification requirements should be verified against specific design standards.

Q: What is the moisture sensitivity level for these parts?

A: The TML-134-01-S-D does not specify MSL in available data. The 6-104068-8 specifies MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.
