Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Matching Parameters:

• 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 compatible

Acceptable Variation Parameters:

• Shrouding configuration (4-wall vs. 2-wall designs)
• Contact shape (square vs. circular)
• Insulation material (LCP vs. thermoplastic)
• Fastening mechanism (push-pull vs. latch holder)
• Contact length specifications within mating interface tolerance
• Operating temperature range (substitute may have narrower range)

The substitute part 5-104068-2 (TE Connectivity AMP Connectors) satisfies all mandatory matching parameters while introducing acceptable variations in shrouding design, contact geometry, and fastening type. Both parts maintain ROHS3 compliance and solder termination methodology.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The TML-105-01-S-D remains the specified component for applications requiring the exact 4-wall shrouded configuration, push-pull fastening mechanism, phosphor bronze contact material, and LCP insulation with the full -55°C to 125°C operating temperature range.

The 5-104068-2 substitute is applicable in applications where the following conditions are met:

1. Temperature Range Compatibility: The application operating temperature does not exceed 105°C or fall below -65°C. If the application requires operation below -65°C or above 105°C, the TML-105-01-S-D is required.

2. Shrouding Configuration: The 2-wall shrouded design of the 5-104068-2 is acceptable for the application. The reduced shrouding does not compromise electrical isolation or mechanical stability in the intended use case.

3. Fastening Mechanism: The latch holder fastening type of the 5-104068-2 is compatible with the mating connector interface. The push-pull mechanism of the TML-105-01-S-D is not a functional requirement.

4. Contact Geometry: The circular contact shape of the 5-104068-2 provides equivalent electrical performance and mating force characteristics compared to the square contact geometry of the TML-105-01-S-D.

5. Insulation Material: The thermoplastic insulation of the 5-104068-2 meets the application's mechanical and thermal requirements. LCP insulation is not a mandatory specification.

6. Regulatory Compliance: Both parts maintain ROHS3 compliance and identical ECCN and HTSUS classifications, ensuring equivalent regulatory status.

Supply Chain Considerations:

The 5-104068-2 maintains higher inventory availability (2422 units vs. 1129 units) and is packaged in tube format, which may provide advantages for automated assembly processes compared to bulk packaging of the TML-105-01-S-D.

Frequently Asked Questions (FAQ)

Q1: Can the 5-104068-2 be used as a direct replacement for the TML-105-01-S-D in all applications?

A: No. The 5-104068-2 is a functional substitute only when the application does not require operation below -65°C or above 105°C. The TML-105-01-S-D supports the extended temperature range of -55°C to 125°C. Additionally, the 2-wall shrouding of the 5-104068-2 differs from the 4-wall shrouding of the TML-105-01-S-D, which may affect electromagnetic shielding characteristics in noise-sensitive applications.

Q2: What are the key differences in contact geometry between these parts?

A: The TML-105-01-S-D features square contact pins, while the 5-104068-2 uses circular contact pins. Both geometries are compatible with standard 0.050" (1.27mm) pitch receptacle designs. The circular geometry of the 5-104068-2 may provide slightly different contact force distribution characteristics.

Q3: Are the fastening mechanisms interchangeable?

A: The TML-105-01-S-D uses a push-pull fastening type, while the 5-104068-2 uses a latch holder mechanism. These are not interchangeable fastening systems. The mating connector must be designed to accommodate the specific fastening type of the header being used.

Q4: Do both parts meet the same regulatory requirements?

A: Yes. Both the TML-105-01-S-D and 5-104068-2 are ROHS3 compliant and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. Both parts are suitable for applications with equivalent regulatory requirements.

Q5: What is the significance of the insulation material difference?

A: The TML-105-01-S-D uses Liquid Crystal Polymer (LCP) insulation, while the 5-104068-2 uses thermoplastic insulation. LCP provides superior dimensional stability and lower moisture absorption. For applications requiring high precision or operation in humid environments, the LCP insulation of the TML-105-01-S-D may be preferred. Thermoplastic insulation is suitable for general-purpose applications.

Q6: How do the contact finish specifications compare?

A: Both parts feature gold-plated mating contacts with identical 30.0µin (0.76µm) thickness and tin-plated posts. The contact finish specifications are equivalent, ensuring comparable corrosion resistance and electrical performance.

Q7: What packaging considerations should be evaluated?

A: The TML-105-01-S-D is supplied in bulk packaging, while the 5-104068-2 is supplied in tube packaging. Tube packaging is typically preferred for automated pick-and-place assembly processes. Bulk packaging may be more suitable for manual assembly or applications requiring flexible quantity handling.

Q8: Are there any contact material compatibility concerns?

A: The TML-105-01-S-D uses phosphor bronze contacts, while the 5-104068-2 uses copper alloy contacts. Both materials provide equivalent electrical conductivity and are suitable for standard solder termination. Phosphor bronze offers slightly superior spring characteristics and fatigue resistance, which may be relevant for high-cycle mating applications.

Q9: What is the voltage rating difference between these parts?

A: The TML-105-01-S-D does not specify a voltage rating in the provided data. The 5-104068-2 specifies a 30VAC voltage rating. For applications requiring voltage ratings above 30VAC, verification of the TML-105-01-S-D voltage capability is necessary through the manufacturer's detailed specifications.

Q10: Can the 5-104068-2 be used in applications requiring the full -55°C to 125°C temperature range?

A: No. The 5-104068-2 operating temperature range is -65°C to 105°C, which does not support operation above 105°C. Applications requiring sustained operation at temperatures between 105°C and 125°C must use the TML-105-01-S-D.
