TML-117-01-G-D Equivalent & Substitute Parts

Part Overview

The TML-117-01-G-D is a shrouded rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board applications. This 34-position connector operates at 0.050" (1.27mm) pitch with 2-row configuration and 0.100" (2.54mm) row spacing. The component features gold-plated phosphor bronze contacts, liquid crystal polymer insulation, and push-pull fastening. With active product status and ROHS3 compliance, this connector serves general-purpose interconnection requirements in industrial and commercial applications. Equivalent substitute parts may be required due to inventory availability, lead time considerations, or specific application constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TML-117-01-G-D is determined by strict alignment of the following critical parameters:

Primary Matching Criteria:

• Connector type: Header
• Contact type: Male Pin
• Number of positions: 34
• 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 Factors:

• Shrouding configuration (shrouded design)
• Contact finish on mating surface (gold plating)
• Insulation material compatibility
• Operating temperature range overlap
• Board-to-board or board-to-cable style compatibility

The substitute parts 1-104068-3 and 6-104068-3 (TE Connectivity AMP Connectors, AMPMODU System 50 series) satisfy all primary matching criteria. Both parts are 34-position, 2-row headers with 0.050" pitch and 0.100" row spacing, through-hole mounted with solder termination and gold-plated mating contacts. Differences in shrouding wall count (2-wall versus 4-wall), contact shape (circular versus square), insulation material (thermoplastic versus LCP), and fastening type (latch holder versus push-pull) represent design variations that may affect mechanical fit and application suitability.

Parameter Comparison

Engineering Selection Recommendations

TML-117-01-G-D (Primary Component): This connector is the specified reference part with active product status and ROHS3 compliance. Selection is appropriate for applications requiring 4-wall shrouding, push-pull fastening, LCP insulation material, and the extended upper operating temperature of 125°C. The square contact geometry and phosphor bronze material provide specific mechanical and electrical characteristics. This part is suitable for applications with strict RoHS3 compliance requirements.

6-104068-3 (Preferred Substitute): This TE Connectivity part maintains ROHS3 compliance, matching the regulatory status of the primary component. It provides the highest inventory availability (2250 pcs) and identical core electrical specifications (34 positions, 0.050" pitch, 2-row configuration). The 2-wall shrouding, latch holder fastening, and thermoplastic insulation represent design differences that may affect mechanical fit in existing connector receptacles. The operating temperature range (-65°C to 105°C) covers most industrial applications, though the upper limit is 20°C lower than the primary part. This substitute is suitable for applications where RoHS3 compliance and inventory availability are prioritized.

1-104068-3 (Alternative Substitute): This TE Connectivity part shares identical core specifications with 6-104068-3 but carries RoHS non-compliant status. Selection is restricted to applications where RoHS compliance is not required. The 1184 pcs inventory availability is lower than 6-104068-3. This part should be considered only when regulatory compliance is not a constraint and 6-104068-3 is unavailable.

Frequently Asked Questions (FAQ)

Q: Can 1-104068-3 or 6-104068-3 be directly substituted for TML-117-01-G-D in existing designs?

A: Direct substitution requires verification of mechanical compatibility. The primary differences are shrouding wall count (4-wall versus 2-wall), fastening mechanism (push-pull versus latch holder), and contact shape (square versus circular). These differences may affect fit with existing mating connectors or receptacles. PCB layout and connector receptacle specifications must be reviewed before substitution.

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

A: The TML-117-01-G-D features 4-wall shrouding, providing full perimeter protection. The substitute parts (1-104068-3 and 6-104068-3) feature 2-wall shrouding, which provides reduced mechanical protection. This difference affects the connector's ability to guide mating and may impact EMI shielding characteristics. Mechanical fit with mating receptacles designed for 4-wall shrouding may be compromised.

Q: How do the fastening type differences affect application suitability?

A: The TML-117-01-G-D uses push-pull fastening, while both substitute parts use latch holder fastening. These mechanisms provide different mating and unmating forces and require different connector receptacles. Applications requiring push-pull engagement cannot use latch holder substitutes without receptacle redesign.

Q: Are there temperature range limitations when substituting?

A: The TML-117-01-G-D operates from -55°C to 125°C. Both substitute parts operate from -65°C to 105°C. The substitute parts have a lower maximum temperature (20°C reduction). Applications requiring operation above 105°C must use the primary TML-117-01-G-D part. The lower minimum temperature of the substitutes (-65°C versus -55°C) provides extended cold-temperature capability.

Q: What is the difference between 1-104068-3 and 6-104068-3?

A: Both parts are identical in electrical and mechanical specifications. The primary difference is RoHS compliance status: 1-104068-3 is RoHS non-compliant, while 6-104068-3 is ROHS3 compliant. For applications requiring RoHS3 compliance, 6-104068-3 is the appropriate choice. Additionally, 6-104068-3 has higher inventory availability (2250 pcs versus 1184 pcs).

Q: How do contact finish thickness differences affect performance?

A: The TML-117-01-G-D has 10.0µin (0.25µm) gold plating on mating contacts, while both substitutes have 30.0µin (0.76µm) gold plating. Thicker gold plating provides enhanced corrosion resistance and extended contact life in high-cycle mating applications. The substitute parts offer superior contact durability in this regard.

Q: Can these connectors be used interchangeably in cable applications?

A: The TML-117-01-G-D is specified for board-to-board style only. Both substitute parts support board-to-board or cable style applications, providing greater application flexibility. However, cable-style use of substitutes requires appropriate mating connectors designed for cable termination.

Q: What packaging considerations apply to these parts?

A: The TML-117-01-G-D is supplied in bulk packaging (814 pcs available). Both substitute parts are supplied in tube packaging (1-104068-3: 1184 pcs; 6-104068-3: 2250 pcs). Packaging format may affect handling, storage, and integration into assembly processes.
