TMS-110-02-G-D Equivalent & Substitute Parts

Part Overview

The TMS-110-02-G-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board applications. This 20-position, 2-row connector operates across a temperature range of -55°C to 125°C and features gold-plated phosphor bronze contacts rated at 5A per contact. The part maintains active product status with full RoHS3 compliance and MSL Level 1 rating. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory requirements necessitate qualified alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitute part 5-103916-2 (TE Connectivity AMP Connectors) qualifies as an equivalent based on the following critical parameters:

Matching Parameters:

• Connector type: Header
• Contact type: Male Pin
• Number of positions: 20
• Number of rows: 2
• Pitch - mating: 0.050" (1.27mm)
• Row spacing - mating: 0.100" (2.54mm)
• Mounting type: Through Hole
• Termination: Solder
• Fastening type: Push-Pull
• Shrouding: Unshrouded
• Insulation material flammability: UL94 V-0
• RoHS3 compliance: Yes
• MSL rating: 1 (Unlimited)

The substitute part maintains functional and mechanical compatibility through identical pitch spacing, position count, and mounting methodology. Both parts support push-pull fastening and solder termination on through-hole PCB applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TMS-110-02-G-D and 5-103916-2 maintain active product status and full RoHS3 compliance with MSL Level 1 ratings, qualifying them for equivalent use in through-hole board-to-board connector applications requiring 20-position, 2-row headers with 1.27mm pitch spacing.

The TMS-110-02-G-D supports an operating temperature maximum of 125°C compared to the substitute's 105°C maximum. Applications requiring sustained operation above 105°C necessitate the primary part.

The substitute part 5-103916-2 provides thicker gold plating on mating contacts (30.0µin versus 10.0µin) and supports both board-to-board and cable configurations, offering expanded application flexibility. The substitute's tin-plated posts differ from the gold-plated posts of the primary part.

Contact length variations exist between the parts: the main part features a 0.120" post length versus the substitute's 0.100" post length, with corresponding differences in mating contact lengths. These dimensional differences may affect PCB layout and mating depth considerations in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can 5-103916-2 directly replace TMS-110-02-G-D in all applications?

A: Both parts share identical pitch spacing (1.27mm), position count (20), row configuration (2), and mounting methodology (through-hole solder termination). However, the substitute operates at a lower maximum temperature (105°C versus 125°C) and features different contact materials and finishes. Applications operating above 105°C require the primary part. Verify post length compatibility with your PCB design, as the substitute features a 0.020" shorter post.

Q: What are the key differences in contact materials?

A: The TMS-110-02-G-D uses phosphor bronze contacts with gold plating on both mating and post surfaces. The 5-103916-2 uses copper alloy contacts with gold-plated mating surfaces and tin-plated posts. These material differences may affect corrosion resistance and electrical performance in specific environments.

Q: Does the substitute support cable applications?

A: Yes. The 5-103916-2 is specified for board-to-board or cable configurations, while the TMS-110-02-G-D is specified for board-to-board only. This provides additional application flexibility with the substitute part.

Q: Are both parts RoHS3 compliant?

A: Yes. Both TMS-110-02-G-D and 5-103916-2 maintain ROHS3 compliance and MSL Level 1 ratings, suitable for standard manufacturing and storage conditions.

Q: What is the significance of the different gold plating thicknesses?

A: The substitute features 30.0µin (0.76µm) gold plating on mating contacts compared to the primary part's 10.0µin (0.25µm). Thicker plating generally provides enhanced durability and corrosion resistance in high-cycle mating applications. The primary part's thinner plating is sufficient for standard board-to-board connections.
