TML-115-01-G-D-SM Equivalent & Substitute Parts

Part Overview

The TML-115-01-G-D-SM is a shrouded rectangular connector header manufactured by Samtec Inc., designed for surface mount board-to-board applications. This 30-position connector operates across a wide temperature range of -55°C to 125°C and features a 0.050" (1.27mm) pitch with 0.100" (2.54mm) row spacing. The part is currently in active production status with 958 units available in inventory. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part becomes unavailable or when design requirements permit alternative contact geometries or insulation materials.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TML-115-01-G-D-SM is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Pitch - Mating: 0.050" (1.27mm)
• Number of Positions: 30
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Surface Mount
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Style: Board to Board or Board to Board/Cable

Allowable Variations:

• Contact Shape: Square or Circular
• Contact Length - Mating: Within tolerance range (0.120" to 0.125")
• Insulation Height: Within tolerance range (0.380" to 0.435")
• Contact Finish - Mating: Gold (consistent across parts)
• Contact Material: Phosphor Bronze or Copper Alloy
• Insulation Material: Liquid Crystal Polymer (LCP) or Polyphthalamide (PPA)
• Fastening Type: Push-Pull or Latch Holder
• Operating Temperature Range: Must encompass or match the original range

The substitute part 5-104549-5 (TE Connectivity AMP Connectors) meets all mandatory matching parameters and operates within acceptable tolerance variations for contact geometry and insulation materials.

Engineering Selection Recommendations

Primary Part Selection: The TML-115-01-G-D-SM remains the preferred choice when available, as it provides the full operating temperature range of -55°C to 125°C and is supplied in tube packaging suitable for controlled component handling.

Substitute Part Selection: The 5-104549-5 (TE Connectivity AMP Connectors AMPMODU System 50) is electrically and mechanically compatible for applications where the operating temperature range does not require the full -55°C to 125°C specification. This substitute is suitable when the application operates within the overlapping temperature range of -55°C to 105°C. Both parts are ROHS3 compliant and carry the same ECCN (EAR99) and HTSUS (8536.69.4040) classifications, confirming regulatory equivalence.

The substitute part features a Latch Holder fastening mechanism compared to the Push-Pull mechanism of the primary part, and includes a Board Lock feature. The circular contact geometry and PPA insulation material of the substitute represent allowable variations that do not compromise electrical or mechanical performance for board-to-board interconnection applications.

The substitute part is available in significantly higher inventory (162,900 units) compared to the primary part (958 units), making it suitable for high-volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5-104549-5 be used as a direct replacement for the TML-115-01-G-D-SM in all applications?

A: The 5-104549-5 is compatible for applications operating within the overlapping temperature range of -55°C to 105°C. If your application requires operation above 105°C or below -55°C, the TML-115-01-G-D-SM is required. Both parts share identical pitch (0.050"), position count (30), row configuration (2 rows), and row spacing (0.100"), ensuring mechanical and electrical compatibility within the specified temperature envelope.

Q: What are the differences in contact geometry between these parts?

A: The TML-115-01-G-D-SM features square contacts, while the 5-104549-5 features circular contacts. Both contact shapes are acceptable for 0.050" pitch board-to-board applications and provide equivalent electrical performance. The contact length varies slightly (0.120" versus 0.125"), which falls within acceptable tolerance ranges for this connector category.

Q: How do the fastening mechanisms differ?

A: The TML-115-01-G-D-SM uses a Push-Pull fastening type, while the 5-104549-5 uses a Latch Holder mechanism with an integrated Board Lock feature. Both mechanisms provide secure mating and demating. The Latch Holder mechanism in the substitute part offers additional retention through the Board Lock feature, which may provide enhanced stability in high-vibration environments.

Q: Are there packaging considerations when switching between these parts?

A: The TML-115-01-G-D-SM is supplied in tube packaging, while the 5-104549-5 is supplied in bulk packaging. Tube packaging provides individual component protection and is preferred for controlled assembly environments. Bulk packaging requires additional handling procedures to prevent component damage. Verify your assembly process compatibility with bulk packaging before selecting the substitute part.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the TML-115-01-G-D-SM and 5-104549-5 are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. The substitute part includes UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity level, confirming suitability for industrial and commercial applications.

Q: What is the impact of different insulation materials on performance?

A: The TML-115-01-G-D-SM uses Liquid Crystal Polymer (LCP) insulation, while the 5-104549-5 uses Polyphthalamide (PPA) insulation. Both materials provide excellent electrical insulation properties and dimensional stability for 0.050" pitch applications. PPA offers slightly higher insulation height (0.435" versus 0.380"), which may require verification in space-constrained PCB layouts.
