Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TML-113-03-S-D is determined by the following critical parameters that must match or be compatible:

Primary Matching Criteria:

• Number of Positions: 26
• Pitch - Mating: 0.050" (1.27mm)
• 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

Secondary Compatibility Factors:

• Operating Temperature Range (minimum -55°C, maximum 125°C or broader)
• Contact Finish - Mating: Gold plating
• Insulation Material: LCP or equivalent thermoplastic
• Shrouding Configuration: Shrouded design

The substitute parts 1-104068-2 and 6-104068-2 (TE Connectivity AMP Connectors, AMPMODU System 50 series) satisfy all primary matching criteria. Both parts feature identical position count, pitch, row spacing, and mounting configuration. Differences in shrouding design (4-wall versus 2-wall), contact shape (square versus circular), and operating temperature range represent acceptable variations within the rectangular connector category for board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

TML-113-03-S-D (Primary Part): The TML-113-03-S-D remains the primary specification for applications requiring ROHS3 compliance and the extended upper operating temperature of 125°C. This part is suitable for industrial and high-temperature applications. The 4-wall shrouding provides enhanced mechanical protection and keying slot functionality. Samtec inventory of 655 units supports standard lead-time requirements.

1-104068-2 (TE Connectivity Substitute): The 1-104068-2 is suitable for applications where the operating temperature range of -65°C to 105°C is acceptable and RoHS compliance is not required. This part features 2-wall shrouding and latch holder fastening. TE Connectivity inventory of 858 units provides alternative supply availability. The circular contact geometry differs from the TML-113-03-S-D square contact design.

6-104068-2 (TE Connectivity Substitute): The 6-104068-2 is functionally equivalent to the 1-104068-2 with RoHS compliance certification. This part is recommended for applications requiring RoHS compliance where the -65°C to 105°C operating temperature range is acceptable. The highest inventory level (1045 units) among all three parts supports extended availability. Both TE Connectivity parts support board-to-board or cable applications, providing additional design flexibility.

Compliance Considerations:

• TML-113-03-S-D: ROHS3 Compliant
• 1-104068-2: RoHS status not applicable
• 6-104068-2: RoHS Compliant

All three parts carry EAR99 ECCN classification and share identical HTSUS code 8536.69.4040.

Frequently Asked Questions (FAQ)

Q: Can the 1-104068-2 or 6-104068-2 directly replace the TML-113-03-S-D in all applications?

A: Direct replacement is possible for applications where the operating temperature range of -65°C to 105°C is acceptable. The TML-113-03-S-D operates to 125°C maximum, which is 20°C higher. Applications requiring the extended upper temperature limit must use the TML-113-03-S-D. The 2-wall shrouding of TE Connectivity parts differs from the 4-wall design of the Samtec part, which may affect mechanical fit in constrained board layouts.

Q: What are the key differences between the TML-113-03-S-D and the TE Connectivity substitutes?

A: Primary differences include: (1) Shrouding configuration: TML-113-03-S-D uses 4-wall shrouding versus 2-wall for TE parts; (2) Contact shape: TML-113-03-S-D has square contacts versus circular for TE parts; (3) Operating temperature: TML-113-03-S-D extends to 125°C versus 105°C maximum for TE parts; (4) Fastening type: TML-113-03-S-D uses push-pull versus latch holder for TE parts; (5) Insulation material: TML-113-03-S-D uses LCP versus thermoplastic for TE parts. All three parts share identical pitch, position count, row spacing, and through-hole mounting configuration.

Q: Are there RoHS compliance differences between the substitute parts?

A: Yes. The TML-113-03-S-D is ROHS3 compliant. The 1-104068-2 has RoHS status listed as not applicable. The 6-104068-2 is RoHS compliant. For applications requiring RoHS certification, either the TML-113-03-S-D or 6-104068-2 are appropriate selections.

Q: What is the impact of different contact materials on substitution?

A: The TML-113-03-S-D uses phosphor bronze contacts, while both TE Connectivity parts use copper alloy contacts. Both materials are standard for rectangular connectors and provide equivalent electrical performance for board-to-board applications. Contact finish specifications are identical (30.0µin gold plating on mating surfaces), ensuring compatible mating characteristics.

Q: How do packaging differences affect part selection?

A: The TML-113-03-S-D is supplied in bulk packaging, while both TE Connectivity substitutes are supplied in tube packaging. Packaging format does not affect electrical or mechanical compatibility but may influence inventory management, handling procedures, and cost per unit. Bulk packaging typically supports higher-volume production environments, while tube packaging is standard for component distribution.

Q: Can the board-to-board or cable style designation of TE parts affect compatibility?

A: The TE Connectivity parts are designated as "Board to Board or Cable" style, while the TML-113-03-S-D is specified as "Board to Board" only. This designation indicates that TE parts can accommodate both board-to-board and cable-to-board mating configurations. For applications using only board-to-board connections, this difference does not affect compatibility. The additional cable compatibility of TE parts provides design flexibility without compromising board-to-board performance.

Q: What inventory considerations should influence part selection?

A: Current inventory levels are: TML-113-03-S-D (655 units), 1-104068-2 (858 units), and 6-104068-2 (1045 units). The 6-104068-2 offers the highest availability. For applications with extended lead-time requirements or high-volume production, the 6-104068-2 provides the most robust supply position while maintaining RoHS compliance and compatibility with the primary specification.
