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

Part Overview

The TMS-110-02-S-D is a 0.050" (1.27mm) pitch micro header connector manufactured by Samtec Inc., designed for board-to-board applications with through-hole solder termination. This 20-position, 2-row unshrouded header features male pins with gold-plated mating contacts and tin-plated posts, operating across -55°C to 125°C. The part is active in production status and ROHS3 compliant. Equivalent parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable or when alternative sourcing is required.

Parameter Comparison

Engineering Selection Recommendations

Both the TMS-110-02-S-D and 5-103916-2 are active production parts with ROHS3 compliance and MSL 1 rating, suitable for equivalent substitution in board-to-board connector applications. The primary differences are in contact material composition (Phosphor Bronze versus Copper Alloy), insulation material (LCP versus Thermoplastic), and operating temperature ranges. The TMS-110-02-S-D supports a wider upper temperature limit (-55°C to 125°C), while the 5-103916-2 extends the lower temperature range to -65°C. Contact length variations are minor (0.320" versus 0.325" overall) and do not affect standard PCB mounting compatibility. Both parts maintain identical pitch, position count, row spacing, and contact finish specifications required for direct mechanical and electrical substitution.

Frequently Asked Questions (FAQ)

Q: Can the 5-103916-2 be used as a direct replacement for the TMS-110-02-S-D?

A: Yes. Both connectors share identical mating pitch (0.050"), position count (20), row configuration (2 rows), row spacing (0.100"), contact type (male pin), mounting method (through-hole solder), and contact finishes (gold mating, tin post). The connectors are mechanically and electrically compatible for board-to-board applications.

Q: What are the differences in contact length between these parts?

A: The TMS-110-02-S-D has a mating contact length of 0.100" with a 0.120" post length, while the 5-103916-2 has a 0.125" mating contact length with a 0.100" post length. Overall contact lengths differ by 0.005" (8.13" versus 8.26"). These variations are within standard PCB mounting tolerances and do not affect compatibility.

Q: Are there temperature rating differences I should consider?

A: The TMS-110-02-S-D operates from -55°C to 125°C, while the 5-103916-2 operates from -65°C to 105°C. The Samtec part supports higher maximum temperature; the TE Connectivity part supports lower minimum temperature. Select based on your application's specific temperature requirements.

Q: Do both parts have the same insulation material?

A: No. The TMS-110-02-S-D uses Liquid Crystal Polymer (LCP), while the 5-103916-2 uses Thermoplastic. Both materials are UL94 V-0 rated and suitable for standard board-to-board applications. LCP offers superior dimensional stability and lower moisture absorption.

Q: Are both parts RoHS compliant?

A: Yes. Both the TMS-110-02-S-D and 5-103916-2 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, suitable for standard manufacturing and storage conditions.

Q: What is the current rating for the 5-103916-2?

A: The current rating for the 5-103916-2 is not specified in the provided data. The TMS-110-02-S-D is rated at 5A per contact. Consult the TE Connectivity datasheet for the 5-103916-2 current rating specifications.
