Substitute Part Grouping Explanation

Substitute parts for the TML-115-01-G-D are identified based on strict alignment of core electrical and mechanical parameters that define connector interchangeability. The substitution logic is based on the following criteria:

Primary Matching Parameters:

• Connector type: Header
• Contact type: Male Pin
• Pitch - Mating: 0.050" (1.27mm)
• Number of positions: 30
• Number of rows: 2
• Row spacing - Mating: 0.100" (2.54mm)
• Mounting type: Through Hole
• Termination: Solder
• Style: Board to Board (or Board to Board or Cable)
• Contact finish - Mating: Gold

Identified Substitutes:

The TE Connectivity AMP Connectors parts 104068-3 and 5-104068-3 meet the primary matching parameters. Both are shrouded rectangular connector headers with 30 positions in a 2-row configuration, 0.050" pitch, and gold-plated mating contacts. These parts are suitable for applications requiring equivalent board-to-board through-hole solder termination connectors.

Parameter Variations in Substitutes:

• Shrouding: 2-wall (vs. 4-wall on main part)
• Contact shape: Circular (vs. Square on main part)
• Fastening type: Latch Holder (vs. Push-Pull on main part)
• Operating temperature: -65°C ~ 105°C (vs. -55°C ~ 125°C on main part)
• Contact finish - Post: Tin-Lead or Tin (vs. Gold on main part)
• Insulation material: Thermoplastic (vs. LCP on main part)
• RoHS status: 104068-3 is non-compliant; 5-104068-3 is ROHS3 compliant

Parameter Comparison

Engineering Selection Recommendations

TML-115-01-G-D (Primary Part): The TML-115-01-G-D is the specified component with ROHS3 compliance and active production status. It features a 4-wall shrouded design, square contact geometry, and push-pull fastening. The operating temperature range extends to 125°C, supporting high-temperature applications. This part is suitable for designs requiring maximum shrouding protection and extended thermal performance.

104068-3 (TE Connectivity - Non-Compliant Substitute): The 104068-3 is functionally equivalent in core electrical and mechanical parameters but carries RoHS non-compliance status. This part features 2-wall shrouding, circular contacts, and latch-holder fastening. The operating temperature range is limited to 105°C. This substitute is applicable only to designs where RoHS compliance is not a regulatory requirement and where the reduced operating temperature range is acceptable.

5-104068-3 (TE Connectivity - Compliant Substitute): The 5-104068-3 is functionally equivalent with ROHS3 compliance matching the primary part. It shares the same core specifications as 104068-3 but meets current regulatory requirements. The 2-wall shrouding, circular contacts, and latch-holder fastening differ from the primary part. The operating temperature range is limited to 105°C. This substitute is suitable for designs requiring RoHS compliance where the reduced operating temperature and alternative fastening mechanism are acceptable.

Compliance Considerations:

• Primary part (TML-115-01-G-D): ROHS3 Compliant
• Substitute 104068-3: RoHS non-compliant (not suitable for regulated applications)
• Substitute 5-104068-3: ROHS3 Compliant (suitable for regulated applications)

Temperature Range Considerations: Applications requiring operation above 105°C must use the primary part TML-115-01-G-D, which supports -55°C to 125°C. Both TE Connectivity substitutes are limited to -65°C to 105°C.

Frequently Asked Questions (FAQ)

Q: Can 104068-3 or 5-104068-3 be used as direct replacements for TML-115-01-G-D?

A: Both TE Connectivity parts match the core electrical and mechanical parameters: 30-position, 0.050" pitch, 2-row configuration, through-hole solder termination, and gold-plated mating contacts. However, differences exist in shrouding design (2-wall vs. 4-wall), contact shape (circular vs. square), fastening mechanism (latch holder vs. push-pull), and operating temperature range (-65°C to 105°C vs. -55°C to 125°C). Substitution is valid only when these differences are acceptable for the application.

Q: What is the difference between 104068-3 and 5-104068-3?

A: Both parts are from the TE Connectivity AMPMODU System 50 series with identical electrical and mechanical specifications. The primary difference is RoHS compliance status: 104068-3 is RoHS non-compliant, while 5-104068-3 is ROHS3 compliant. For applications subject to RoHS regulations, 5-104068-3 is the appropriate choice.

Q: Are the shrouding differences significant?

A: Yes. The TML-115-01-G-D features 4-wall shrouding, providing maximum protection against cross-talk and accidental contact. The TE Connectivity substitutes feature 2-wall shrouding, which provides reduced mechanical protection. Applications requiring maximum EMI shielding or physical protection should retain the primary part.

Q: What is the impact of the contact shape difference?

A: The TML-115-01-G-D uses square contacts, while the TE Connectivity substitutes use circular contacts. This difference affects contact engagement geometry and mating force characteristics. Designs must verify compatibility with mating connectors before substitution.

Q: Can I use these parts in applications exceeding 105°C?

A: No. Both TE Connectivity substitutes are rated only to 105°C maximum operating temperature. The TML-115-01-G-D supports operation to 125°C. Applications requiring higher temperature operation must use the primary part.

Q: What is the packaging difference?

A: The TML-115-01-G-D is supplied in bulk packaging. The TE Connectivity substitutes are supplied in tube packaging. This affects handling, storage, and inventory management but does not impact electrical or mechanical performance.

Q: Are there any compliance concerns with substitution?

A: The 104068-3 is RoHS non-compliant and unsuitable for applications subject to RoHS regulations. The 5-104068-3 is ROHS3 compliant and suitable for regulated applications. Verify regulatory requirements before selecting a substitute.
