Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TML-150-01-G-D is determined by strict alignment with the following critical parameters:

Critical Parameters (Must Match Exactly):

• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.050" (1.27mm)
• Number of Positions: 100
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder

Important Parameters (Acceptable Variation Within Limits):

• Shrouding configuration (4-wall vs. 2-wall acceptable for board-to-board applications)
• Contact shape (square vs. circular acceptable)
• Insulation material (LCP vs. Thermoplastic acceptable)
• Operating temperature range (substitute range must encompass or overlap primary application range)
• Contact finish thickness (variation acceptable if mating surface is gold-plated)

The substitute parts 1-104068-7 and 6-104068-7 (both TE Connectivity AMP Connectors) satisfy all critical parameters and are therefore qualified as direct substitutes for the TML-150-01-G-D.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: TML-150-01-G-D (Samtec Inc.)

The TML-150-01-G-D is the specified component and remains the primary selection when available. This part is ROHS3 compliant and carries active product status with established supply inventory.

Substitute Option 1: 6-104068-7 (TE Connectivity AMP Connectors)

The 6-104068-7 is the preferred substitute option. This part meets all critical electrical and mechanical parameters required for direct substitution. Key advantages include:

• ROHS3 compliance matching the primary part
• Highest inventory availability (2100 units in stock)
• Active product status
• Operating temperature range of -65°C ~ 105°C (lower minimum temperature provides extended cold-weather capability)
• 30VAC voltage rating specification (primary part voltage rating not specified)

Substitute Option 2: 1-104068-7 (TE Connectivity AMP Connectors)

The 1-104068-7 is a qualified substitute meeting all critical parameters. This part is suitable for applications where the primary part is unavailable. Considerations include:

• RoHS status listed as "Not applicable" (compliance status differs from primary part)
• Operating temperature range of -65°C ~ 105°C
• Tin-Lead post finish (differs from primary part gold finish)
• Lower inventory availability (999 units in stock) compared to 6-104068-7

Compliance and Regulatory Status:

Both substitute parts are manufactured by TE Connectivity, an established connector supplier. The 6-104068-7 maintains ROHS3 compliance alignment with the primary part. The 1-104068-7 RoHS status is listed as "Not applicable," which may require verification for applications with mandatory RoHS compliance requirements.

Mechanical and Electrical Compatibility:

All three parts support identical mating pitch (0.050"), position count (100), row configuration (2 rows at 0.100" spacing), and through-hole solder termination. Minor dimensional variations in contact length and insulation height are within acceptable tolerances for standard PCB footprints designed for 0.050" pitch 100-position headers.

Frequently Asked Questions (FAQ)

Q1: Can the 1-104068-7 or 6-104068-7 be used as direct replacements for the TML-150-01-G-D on existing PCB designs?

A: Yes. Both TE Connectivity parts are direct mechanical and electrical substitutes. The 0.050" (1.27mm) mating pitch, 100-position count, 2-row configuration, and 0.100" (2.54mm) row spacing are identical. PCB footprints designed for the TML-150-01-G-D will accommodate either substitute part without modification. Minor differences in contact length (0.120" vs. 0.125" mating contact) and insulation height (0.380" vs. 0.390") are within standard manufacturing tolerances and do not affect board-level compatibility.

Q2: What are the key differences between the TML-150-01-G-D and the substitute parts?

A: The primary differences are:

• Shrouding: TML-150-01-G-D features 4-wall shrouding; substitutes feature 2-wall shrouding
• Contact shape: TML-150-01-G-D uses square contacts; substitutes use circular contacts
• Insulation material: TML-150-01-G-D uses Liquid Crystal Polymer (LCP); substitutes use Thermoplastic
• Contact finish on posts: TML-150-01-G-D is gold-plated; 1-104068-7 is tin-lead; 6-104068-7 is tin
• Operating temperature minimum: TML-150-01-G-D operates to -55°C; substitutes operate to -65°C
• RoHS compliance: TML-150-01-G-D and 6-104068-7 are ROHS3 compliant; 1-104068-7 status is "Not applicable"

Q3: Which substitute part should be selected for new designs?

A: The 6-104068-7 is recommended for new designs. This part offers ROHS3 compliance matching the primary part, highest inventory availability, and active product status. The extended operating temperature range (-65°C minimum) provides additional design margin for temperature-sensitive applications.

Q4: Are there any compatibility concerns with the 2-wall shrouding on substitute parts versus the 4-wall shrouding on the primary part?

A: No compatibility concerns exist for standard board-to-board applications. The 2-wall shrouding on TE Connectivity parts provides adequate mechanical guidance and keying for mating connector insertion. The 4-wall shrouding on the TML-150-01-G-D offers additional mechanical protection and EMI shielding. Selection between 2-wall and 4-wall shrouding should be based on specific application requirements for mechanical robustness and electromagnetic interference control.

Q5: What is the impact of different contact materials (Phosphor Bronze vs. Copper Alloy)?

A: Both materials are standard for connector applications and provide equivalent electrical conductivity and mechanical performance. Phosphor Bronze (primary part) and Copper Alloy (substitute parts) are both suitable for solder termination and gold-plated mating surfaces. Material selection does not affect electrical performance or reliability for standard board-to-board connector applications.

Q6: Does the difference in contact finish thickness (10.0µin vs. 30.0µin on mating surfaces) affect performance?

A: No. Both gold plating thicknesses are within industry standards for connector applications. The 30.0µin (0.76µm) thickness on substitute parts provides slightly enhanced corrosion resistance and contact durability. The 10.0µin (0.25µm) thickness on the primary part is adequate for standard environmental conditions. Both thicknesses support equivalent electrical performance and mating cycle life.

Q7: What packaging differences exist, and do they affect component selection?

A: The TML-150-01-G-D is supplied in Bulk packaging; substitute parts are supplied in Tube packaging. Packaging format does not affect electrical or mechanical performance. Selection should be based on manufacturing process requirements (bulk vs. tubed component handling) and inventory management practices.

Q8: Are there any voltage or current rating differences that affect application suitability?

A: The primary part (TML-150-01-G-D) does not specify voltage or current ratings in the provided data. The substitute parts specify 30VAC voltage rating. For applications requiring specific voltage or current specifications, the 30VAC rating on substitute parts should be verified against application requirements. Current ratings are not specified for any of the three parts.

Q9: How should RoHS compliance status be evaluated when selecting between parts?

A: For applications with mandatory RoHS compliance requirements, the 6-104068-7 is the appropriate substitute, as it carries ROHS3 compliance matching the primary part. The 1-104068-7 lists RoHS status as "Not applicable," which requires clarification with the supplier for applications subject to RoHS regulations. The primary part TML-150-01-G-D is ROHS3 compliant.

Q10: What is the significance of the operating temperature range difference (-55°C ~ 125°C vs. -65°C ~ 105°C)?

A: The primary part operates from -55°C to 125°C; substitute parts operate from -65°C to 105°C. The substitute parts provide a lower minimum temperature (-65°C vs. -55°C), suitable for extended cold-weather applications. The primary part supports a higher maximum temperature (125°C vs. 105°C). Application selection should be based on the specific temperature range requirements. For applications operating within -55°C to 105°C, both parts are suitable.
