Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TML-105-01-G-D is determined by strict alignment of the following critical parameters:

Primary Matching Criteria:

• Pitch - Mating: 0.050" (1.27mm)
• Number of Positions: 10
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Style: Board to Board or Board to Board/Cable

Secondary Compatibility Factors:

• Operating Temperature Range (minimum -55°C, maximum 125°C or higher)
• RoHS3 Compliance
• Contact Finish: Gold plating on mating surface
• Shrouding configuration (4-wall or 2-wall acceptable for mechanical fit)

The substitute part 5-104068-2 (TE Connectivity AMP Connectors) satisfies all primary matching criteria and maintains RoHS3 compliance. Variations in contact material (copper alloy vs. phosphor bronze), insulation material (thermoplastic vs. LCP), contact finish thickness, and shrouding wall count represent acceptable engineering trade-offs within the rectangular connector category for this pitch and position configuration.

Parameter Comparison

Engineering Selection Recommendations

TML-105-01-G-D Selection Criteria:

• Applications requiring operating temperatures above 105°C (up to 125°C maximum)
• Designs specifying phosphor bronze contact material for specific electrical or mechanical properties
• Liquid Crystal Polymer insulation material requirements
• 4-wall shrouding configuration for enhanced EMI shielding or mechanical robustness
• Square contact geometry specifications
• Thinner gold plating (10.0µin) acceptable for application requirements

5-104068-2 Selection Criteria:

• Applications requiring operating temperatures below -55°C (down to -65°C minimum)
• Designs compatible with copper alloy contact material
• Thermoplastic insulation material acceptable
• 2-wall shrouding configuration sufficient for application
• Circular contact geometry acceptable
• Thicker gold plating (30.0µin) beneficial for high-cycle mating applications
• Board-to-board or cable connection flexibility required
• Automotive, medical, or telecommunications application environments
• 30VAC voltage rating specification

Both parts maintain Active product status and ROHS3 compliance. Selection between TML-105-01-G-D and 5-104068-2 depends on specific operating temperature requirements, contact material specifications, and mechanical design constraints of the target application.

Frequently Asked Questions (FAQ)

Q: Can 5-104068-2 directly replace TML-105-01-G-D in all applications?

A: Direct replacement is possible only when application requirements accommodate the parameter differences listed in the Parameter Comparison table. The substitute part operates at a lower maximum temperature (105°C vs. 125°C) and lower minimum temperature (-65°C vs. -55°C). Contact geometry differs (circular vs. square), and insulation material differs (thermoplastic vs. LCP). Verify these variations against your specific application requirements before substitution.

Q: What are the key mechanical compatibility factors?

A: Both connectors share identical pitch (0.050"), position count (10), row configuration (2 rows), and row spacing (0.100"). Mating interface compatibility is ensured by these parameters. Differences in contact length (0.005" variance), insulation height (0.010" variance), and shrouding wall count (4-wall vs. 2-wall) may affect PCB layout, stacking height, and mechanical clearance. Verify PCB footprint and connector cavity dimensions before substitution.

Q: Are there voltage or current rating differences?

A: The TML-105-01-G-D does not specify voltage or current ratings in the provided data. The 5-104068-2 specifies 30VAC voltage rating. If your application requires specific voltage or current ratings, consult detailed datasheets for both parts to confirm electrical performance specifications.

Q: How do the contact materials affect performance?

A: TML-105-01-G-D uses phosphor bronze contacts; 5-104068-2 uses copper alloy contacts. Both materials are standard for rectangular connectors in this pitch class. Phosphor bronze offers specific mechanical and electrical properties; copper alloy offers alternative performance characteristics. Material selection depends on application-specific requirements for conductivity, spring force, and durability. No universal superiority exists between these materials for this connector category.

Q: What is the significance of gold plating thickness differences?

A: TML-105-01-G-D specifies 10.0µin (0.25µm) gold plating on mating contacts; 5-104068-2 specifies 30.0µin (0.76µm). Thicker gold plating (5-104068-2) provides enhanced corrosion resistance and durability in high-cycle mating applications. Thinner plating (TML-105-01-G-D) is acceptable for standard applications with moderate mating cycles. Both meet RoHS3 requirements. Selection depends on expected connector mating cycles and environmental exposure.

Q: Why do the operating temperature ranges differ?

A: TML-105-01-G-D operates -55°C to 125°C; 5-104068-2 operates -65°C to 105°C. These ranges reflect different insulation material properties (LCP vs. thermoplastic) and design specifications. The TML-105-01-G-D supports higher maximum temperature; the 5-104068-2 supports lower minimum temperature. Select the part whose temperature range encompasses your application's full operating environment.

Q: Are both parts RoHS3 compliant?

A: Yes. Both TML-105-01-G-D and 5-104068-2 are ROHS3 Compliant and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. Both are suitable for applications requiring RoHS3 compliance.

Q: What packaging differences exist?

A: TML-105-01-G-D is supplied in Bulk packaging (932 units in stock). 5-104068-2 is supplied in Tube packaging (2422 units in stock). Packaging format may affect handling, storage, and procurement processes but does not affect connector functionality or compatibility.

Q: Can these connectors be used interchangeably on the same PCB?

A: Interchangeability on the same PCB requires verification of PCB footprint compatibility. Both connectors share identical pitch and position count, ensuring mating interface alignment. However, differences in insulation height (0.010"), contact length, and shrouding configuration may affect PCB layout and component placement. Consult PCB design guidelines and connector datasheets to confirm footprint compatibility before design changes.
