TML-110-03-G-D-RA Equivalent & Substitute Parts

Part Overview

The TML-110-03-G-D-RA is a shrouded rectangular connector header manufactured by Samtec Inc., designed for through-hole, right-angle board-to-board applications. This 20-position connector operates across a wide temperature range of -55°C to 125°C and features gold-plated phosphor bronze contacts with 0.050" (1.27mm) pitch spacing. The part is currently active in production with 951 units in stock and maintains ROHS3 compliance. Equivalent and substitute parts are identified based on matching core electrical and mechanical parameters: connector type, contact configuration, pitch spacing, number of positions, mounting orientation, and termination method.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TML-110-03-G-D-RA are identified based on strict equivalence of the following core parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.050" (1.27mm)
• Number of Positions: 20
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Style: Board to Board or Board to Board/Cable compatible

The substitute parts listed below satisfy these core functional requirements. Variations in secondary parameters such as shrouding wall count, contact length, insulation height, contact shape, and contact finish specifications are noted in the comparison table. These variations do not prevent functional substitution when the core parameters align.

Engineering Selection Recommendations

TML-110-03-G-D-RA (Primary Part)

The TML-110-03-G-D-RA remains the primary specification when the design requires the full operating temperature range of -55°C to 125°C, LCP insulation material, or the specific contact geometry and dimensions provided. This part is ROHS3 compliant and maintains active production status with adequate inventory.

104069-1 (TE Connectivity Substitute)

The 104069-1 provides functional equivalence for applications where the operating temperature range can be limited to -65°C to 105°C. This part is not RoHS applicable but is active in production. The 2-wall shrouding, reduced contact length, and thermoplastic insulation represent design variations from the primary part. Inventory availability is 708 units.

5-104069-1 (TE Connectivity Substitute)

The 5-104069-1 is functionally equivalent to 104069-1 with the addition of RoHS compliance certification. This variant operates within the same temperature range (-65°C to 105°C) and shares identical core connector parameters. This part offers the highest inventory availability at 1095 units and is recommended when RoHS compliance is required and the reduced temperature range is acceptable.

All three parts share the same ECCN (EAR99) and HTSUS classification (8536.69.4040), indicating equivalent regulatory treatment for export and tariff purposes.

Frequently Asked Questions (FAQ)

Q: Can 104069-1 or 5-104069-1 be used as direct replacements for TML-110-03-G-D-RA?

A: Yes, for applications where the operating temperature range of -65°C to 105°C is acceptable. Both parts match the core functional parameters: 20-position, 0.050" pitch, 2-row configuration, through-hole right-angle mounting, and solder termination. Secondary parameter differences (shrouding wall count, contact length, insulation material) do not prevent functional substitution when thermal requirements align.

Q: What is the difference between 104069-1 and 5-104069-1?

A: Both parts are identical in electrical and mechanical function. The primary difference is RoHS compliance status: 104069-1 is not RoHS applicable, while 5-104069-1 is RoHS compliant. The 5-104069-1 variant also has higher inventory availability (1095 units versus 708 units).

Q: Why does TML-110-03-G-D-RA have a higher operating temperature maximum than the TE Connectivity substitutes?

A: The TML-110-03-G-D-RA operates to 125°C while the TE Connectivity parts operate to 105°C. This difference reflects the design specifications of each manufacturer's product line. Selection between these parts depends on whether the application requires the extended upper temperature limit.

Q: Are the contact geometry differences significant?

A: The TML-110-03-G-D-RA uses square contacts with 0.170" mating length, while the TE Connectivity substitutes use circular contacts with 0.125" mating length. These differences are secondary to the core pitch and position parameters. Compatibility depends on the mating connector design; both geometries are standard in the 0.050" pitch rectangular connector category.

Q: What packaging is used for all three parts?

A: All three parts are supplied in tube packaging, suitable for automated assembly processes.

Q: Are there any compliance or certification differences I should consider?

A: The TML-110-03-G-D-RA is ROHS3 compliant. The 104069-1 is not RoHS applicable. The 5-104069-1 is RoHS compliant. All three parts share the same ECCN (EAR99) classification. Selection should align with your product's compliance requirements.
