TMS-111-02-SM-S Equivalent & Substitute Parts

Part Overview

The TMS-111-02-SM-S is a 0.050" (1.27mm) pitch micro header connector manufactured by Samtec Inc., designed for through-hole board-to-board applications. This unshrouded, 11-position single-row header features male pins with gold-plated mating contacts and tin-plated posts, rated for 5A per contact across an operating temperature range of -55°C to 125°C. The connector is ROHS3 compliant and carries a UL94 V-0 flammability rating. Identifying equivalent substitute parts is essential for supply chain continuity, inventory optimization, and design flexibility while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TMS-111-02-SM-S are determined by strict equivalence across the following critical parameters:

• Pitch - Mating: 0.050" (1.27mm)
• Number of Positions: 11
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Current Rating: 5A per Contact
• Operating Temperature: -55°C ~ 125°C
• Contact Material: Phosphor Bronze
• Insulation Material: Liquid Crystal Polymer (LCP)
• RoHS Status: ROHS3 Compliant
• Material Flammability Rating: UL94 V-0

The TMS-111-02-SM-S differs from its substitute counterpart only in fastening type designation within the same TMS series base product number (TMS-111). Substitutes maintain identical electrical performance, mechanical dimensions, and environmental ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the TMS-111-02-SM-S and TMS-111-02-S-S are active products from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain requirements rather than technical differentiation. Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications. The TMS-111-02-S-S currently maintains higher inventory availability (904 pcs vs. 788 pcs), making it a viable alternative for procurement planning. Both connectors are suitable for applications requiring 5A per-contact current capacity across the -55°C to 125°C operating range.

Frequently Asked Questions (FAQ)

Q: Are TMS-111-02-SM-S and TMS-111-02-S-S electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including 5A per-contact current rating, phosphor bronze contact material, and gold-plated mating surfaces with 30.0µin thickness.

Q: Do these connectors have the same physical dimensions?

A: Yes. Both parts have identical mechanical dimensions: 0.050" (1.27mm) pitch, 11 positions in a single row, 0.100" (2.54mm) mating contact length, and 0.320" (8.13mm) overall contact length.

Q: Are both parts RoHS compliant?

A: Yes. Both TMS-111-02-SM-S and TMS-111-02-S-S are ROHS3 compliant with UL94 V-0 flammability ratings.

Q: What is the moisture sensitivity level for these connectors?
