Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TML-113-01-G-D is determined by strict adherence to the following critical parameters:

Critical Matching Parameters:

• Pitch - Mating: 0.050" (1.27mm) — mechanical compatibility with mating connectors
• Number of Positions: 26 — circuit connectivity requirement
• Number of Rows: 2 — physical layout requirement
• Row Spacing - Mating: 0.100" (2.54mm) — board layout compatibility
• Mounting Type: Through Hole — PCB assembly process compatibility
• Termination: Solder — assembly method compatibility
• Contact Type: Male Pin — mating interface requirement

Functional Parameters Allowing Variation:

• Shrouding Configuration: 4 Wall (main part) vs. 2 Wall (substitutes) — both provide shrouded protection with different wall counts
• Contact Shape: Square (main part) vs. Circular (substitutes) — both accommodate standard mating receptacles
• Insulation Material: LCP (main part) vs. Thermoplastic (substitutes) — both provide electrical insulation
• Contact Finish - Post: Gold (main part) vs. Tin-Lead/Tin (substitutes) — both provide solder compatibility
• Fastening Type: Push-Pull (main part) vs. Latch Holder (substitutes) — both provide mechanical retention

Parameters with Acceptable Deviations:

• Operating Temperature: Main part -55°C ~ 125°C; substitutes -65°C ~ 105°C — substitutes cover lower minimum but reduced maximum
• Contact Length - Mating: 0.120" (main) vs. 0.125" (substitutes) — within tolerance for standard mating
• Insulation Height: 0.380" (main) vs. 0.390" (substitutes) — minor dimensional variation
• Contact Finish Thickness - Mating: 10.0µin (main) vs. 30.0µin (substitutes) — both provide adequate gold plating

The substitute parts 1-104068-2 and 6-104068-2 satisfy all critical parameters and maintain functional equivalence for board-to-board connector applications.

Engineering Selection Recommendations

TML-113-01-G-D (Samtec Inc.) — Primary selection for applications requiring:

• Extended maximum operating temperature (125°C vs. 105°C for substitutes)
• ROHS3 compliance certification
• Liquid crystal polymer insulation material
• 4-wall shrouded configuration
• Square contact geometry
• Bulk packaging format

1-104068-2 (TE Connectivity AMP Connectors) — Suitable substitute when:

• Operating temperature maximum of 105°C is acceptable
• Extended minimum operating temperature (-65°C) is beneficial
• Tube packaging format is preferred
• Latch holder fastening mechanism is compatible with application
• Tin-lead post finish is acceptable for solder termination
• Circular contact geometry is compatible with mating receptacles

6-104068-2 (TE Connectivity AMP Connectors) — Preferred substitute when:

• RoHS compliance is required (RoHS Compliant status)
• Operating temperature maximum of 105°C is acceptable
• Extended minimum operating temperature (-65°C) is beneficial
• Tube packaging format is preferred
• Latch holder fastening mechanism is compatible with application
• Tin post finish is acceptable for solder termination
• Circular contact geometry is compatible with mating receptacles
• Higher inventory availability (1045 units) is advantageous

All three parts maintain identical critical parameters: 0.050" pitch, 26 positions, 2 rows, 0.100" row spacing, through-hole mounting, and solder termination. Selection between main part and substitutes depends on specific compliance requirements, temperature operating range, and packaging preferences.

Frequently Asked Questions (FAQ)

Q: Can TML-113-01-G-D be directly replaced with 1-104068-2 or 6-104068-2?

A: Direct replacement is mechanically and electrically feasible for applications where the operating temperature maximum of 105°C is acceptable and the reduced minimum temperature of -65°C does not create operational constraints. The critical parameters—pitch, position count, row spacing, mounting type, and termination method—are identical across all three parts. Differences in shrouding configuration (4-wall vs. 2-wall), contact shape (square vs. circular), and post finish material do not prevent functional substitution in standard board-to-board connector applications.

Q: What is the difference between 1-104068-2 and 6-104068-2?

A: Both parts are identical in electrical and mechanical specifications. The primary differences are: (1) RoHS Status — 1-104068-2 is "Not applicable" while 6-104068-2 is "RoHS Compliant"; (2) Contact Finish - Post — 1-104068-2 uses Tin-Lead while 6-104068-2 uses Tin; (3) REACH Status — 1-104068-2 is "REACH Affected" while 6-104068-2 is "Vendor Undefined"; (4) Inventory — 6-104068-2 has higher stock (1045 units vs. 858 units). For applications requiring RoHS compliance, 6-104068-2 is the appropriate selection.

Q: Why does TML-113-01-G-D have a higher maximum operating temperature than the TE Connectivity substitutes?

A: The TML-113-01-G-D operates to 125°C while substitutes operate to 105°C. This difference reflects design choices in insulation material (LCP vs. Thermoplastic) and overall thermal design. Applications requiring sustained operation above 105°C must use the TML-113-01-G-D or verify that the substitute parts' 105°C maximum is sufficient for the specific thermal environment.

Q: Are the shrouding differences (4-wall vs. 2-wall) significant for substitution?

A: Both configurations provide shrouded protection. The 4-wall shrouding on TML-113-01-G-D offers additional mechanical protection and EMI shielding compared to 2-wall shrouding on substitutes. For applications where enhanced mechanical protection or EMI performance is critical, the 4-wall configuration may be preferred. For standard board-to-board applications, 2-wall shrouding provides adequate protection.

Q: Does the contact shape difference (square vs. circular) affect compatibility?

A: Contact shape differences do not prevent mating with standard receptacles. Both square and circular contact geometries are designed to mate with standard 0.050" pitch receptacles. The choice between square and circular contacts is typically driven by manufacturing process and application-specific requirements rather than fundamental compatibility constraints.

Q: What packaging format differences exist, and does this affect selection?

A: TML-113-01-G-D is supplied in Bulk packaging, while both TE Connectivity substitutes are supplied in Tube packaging. Bulk packaging typically provides loose components for high-volume assembly operations, while tube packaging provides organized component presentation. Selection depends on assembly process requirements and inventory management practices.

Q: Which part should be selected for new designs?

A: For new designs, evaluate the specific operating temperature requirements. If maximum temperature exceeds 105°C, TML-113-01-G-D is required. If maximum temperature of 105°C is acceptable and RoHS compliance is required, 6-104068-2 is the appropriate selection. If RoHS compliance is not required and Tin-Lead post finish is acceptable, 1-104068-2 is a viable option. All three parts are active products with adequate inventory.
