TML-115-01-S-D Equivalent & Substitute Parts

Part Overview

The TML-115-01-S-D is a shrouded rectangular connector header manufactured by Samtec Inc., designed for through-hole 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 active in production with 739 units in stock. Equivalent and substitute parts are identified to provide design flexibility, accommodate supply chain variations, and support alternative sourcing strategies while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

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

Primary Matching Criteria:

• 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: Through Hole
• Termination: Solder
• Style: Board to Board compatibility

Secondary Compatibility Factors:

• Contact Finish - Mating: Gold plating
• Contact Finish Thickness - Mating: 30.0µin (0.76µm)
• Shrouding configuration
• Insulation material properties
• Operating temperature range overlap

The substitute parts 104068-3 and 5-104068-3 (TE Connectivity AMP Connectors, AMPMODU System 50 series) satisfy all primary matching criteria. Both parts maintain the identical pitch, position count, row configuration, and through-hole solder termination required for direct mechanical and electrical substitution. Differences in shrouding design (4-wall versus 2-wall), contact shape (square versus circular), and insulation material (LCP versus thermoplastic) represent acceptable variations within the rectangular connector category and do not preclude functional equivalence in standard board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

TML-115-01-S-D (Primary Part): Select this part when ROHS3 compliance is mandatory and the extended operating temperature range of -55°C to 125°C is required. The 4-wall shrouding design provides enhanced EMI shielding and mechanical protection. LCP insulation material offers superior dimensional stability and chemical resistance. This part is suitable for applications requiring maximum environmental performance and regulatory compliance.

5-104068-3 (Preferred Substitute): This part is the recommended substitute when supply of the primary part is constrained. It maintains ROHS3 compliance, matching the regulatory status of the TML-115-01-S-D. The 2-wall shrouding, thermoplastic insulation, and circular contact geometry represent acceptable design variations for standard board-to-board interconnect applications. The operating temperature range of -65°C to 105°C covers most industrial and commercial applications, though the upper limit is 20°C lower than the primary part. Higher inventory availability (1888 units) supports rapid procurement.

104068-3 (Secondary Substitute): This part provides mechanical and electrical compatibility but carries RoHS non-compliance status. Selection of this part is restricted to applications where RoHS3 compliance is not required or where legacy system compatibility takes precedence. The identical pitch, position count, and row spacing ensure direct mechanical fit. Use this part only when regulatory constraints do not apply and supply of compliant alternatives is unavailable.

Frequently Asked Questions (FAQ)

Q: Can 104068-3 and 5-104068-3 be used interchangeably with TML-115-01-S-D?

A: Both TE Connectivity parts satisfy the core mechanical and electrical requirements for substitution: identical 0.050" pitch, 30 positions, 2-row configuration, and through-hole solder termination. However, 5-104068-3 is the preferred choice due to ROHS3 compliance matching the primary part. The 104068-3 variant is RoHS non-compliant and should be selected only when regulatory requirements do not apply.

Q: What are the differences in shrouding design, and do they affect compatibility?

A: The TML-115-01-S-D features 4-wall shrouding, while both TE Connectivity substitutes employ 2-wall shrouding. Four-wall shrouding provides greater mechanical protection and EMI shielding. Two-wall shrouding reduces overall connector profile and cost. For standard board-to-board applications without stringent EMI requirements, 2-wall shrouding is functionally adequate. Applications requiring maximum shielding should retain the primary part.

Q: How do the operating temperature ranges compare?

A: The TML-115-01-S-D operates from -55°C to 125°C, while both TE Connectivity substitutes operate from -65°C to 105°C. The primary part supports a higher maximum temperature (125°C versus 105°C), a 20°C difference. For applications operating near or above 105°C, the primary part is required. For standard industrial and commercial temperature ranges, the substitute parts are adequate.

Q: What is the significance of contact shape differences (square versus circular)?

A: The TML-115-01-S-D uses square contacts, while the TE Connectivity substitutes use circular contacts. Both geometries are standard in rectangular connector design and provide equivalent electrical performance when mated with compatible receptacles. Contact shape does not affect substitution eligibility for board-to-board applications using standard mating connectors.

Q: Are there packaging differences that affect ordering or handling?

A: The TML-115-01-S-D is supplied in bulk packaging, while both TE Connectivity substitutes are supplied in tube packaging. Tube packaging provides better protection during storage and handling. This difference does not affect electrical or mechanical compatibility but may influence inventory management and procurement workflows.

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

A: For new designs, select 5-104068-3 when supply of the primary part is constrained. This part maintains ROHS3 compliance, ensuring regulatory alignment with the TML-115-01-S-D. The operating temperature range of -65°C to 105°C covers the majority of industrial, commercial, and consumer applications. Verify that the application's maximum operating temperature does not exceed 105°C before finalizing the substitution.

Q: What compliance certifications apply to each part?

A: The TML-115-01-S-D and 5-104068-3 are both ROHS3 compliant. The 104068-3 is RoHS non-compliant. All three parts carry EAR99 ECCN classification and share the same HTSUS code (8536.69.4040). Applications subject to RoHS directives or customer specifications requiring RoHS compliance must use either the primary part or 5-104068-3.
