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

Part Overview

The HTMS-110-02-S-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board applications. This unshrouded header features 20 positions arranged in 2 rows with 0.050" (1.27mm) pitch spacing. The connector is actively produced and widely used in applications requiring reliable solder termination with push-pull fastening. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory constraints require component flexibility.

Key Parameters

Substitute Part Grouping Explanation

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

• Identical pitch spacing: 0.050" (1.27mm)
• Identical position count: 20 positions in 2 rows
• Identical row spacing: 0.100" (2.54mm)
• Identical connector type: Header with male pins
• Identical mounting method: Through-hole solder termination
• Identical fastening mechanism: Push-pull
• Identical contact finish on mating surface: Gold plating at 30.0µin (0.76µm)
• Identical insulation height: 0.100" (2.54mm)
• Identical shrouding: Unsshrouded
• Identical contact shape: Square
• Identical board-to-board style application
• Identical RoHS3 compliance and MSL rating

These parameters define the mechanical and electrical interchangeability envelope for this connector category.

Parameter Comparison

Engineering Selection Recommendations

Both the HTMS-110-02-S-D and 5-103916-2 are active products with ROHS3 compliance and MSL Level 1 ratings, making them suitable for equivalent substitution in board-to-board through-hole applications requiring 20-position headers with 0.050" pitch.

The HTMS-110-02-S-D offers a wider operating temperature range (-55°C to 125°C) and specified current rating of 5A per contact. The 5-103916-2 provides a lower minimum operating temperature (-65°C) and specifies a 30VAC voltage rating. Both connectors feature identical mating pitch, position count, row spacing, and contact finish specifications on the mating surface.

Minor dimensional variations exist in contact lengths and post finishes. The HTMS-110-02-S-D uses Liquid Crystal Polymer insulation, while the 5-103916-2 uses Thermoplastic insulation. Both materials meet UL94 V-0 flammability requirements.

Selection between these parts should be based on specific application requirements regarding operating temperature range, voltage specifications, and insulation material compatibility.

Frequently Asked Questions (FAQ)

Q: What makes 5-103916-2 a suitable substitute for HTMS-110-02-S-D?

A: Both connectors share identical critical parameters: 0.050" (1.27mm) mating pitch, 20 positions in 2 rows, 0.100" (2.54mm) row spacing, through-hole solder termination, push-pull fastening, and gold-plated mating contacts at 30.0µin thickness. These parameters define mechanical and electrical interchangeability for board-to-board header applications.

Q: Are there dimensional differences between these connectors?

A: Yes. The mating contact length differs: HTMS-110-02-S-D is 0.100" (2.54mm) while 5-103916-2 is 0.125" (3.18mm). Post contact lengths also differ: 0.120" (3.05mm) versus 0.100" (2.54mm) respectively. Overall contact length varies by 0.005" (0.13mm). These variations are within typical connector design tolerances for this category.

Q: What is the temperature operating range difference?

A: HTMS-110-02-S-D operates from -55°C to 125°C, while 5-103916-2 operates from -65°C to 105°C. The Samtec part provides higher maximum temperature capability; the TE Connectivity part provides lower minimum temperature capability. Application requirements determine which range is appropriate.

Q: Do both connectors meet the same compliance standards?

A: Yes. Both are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity ratings. Both feature UL94 V-0 flammability-rated insulation materials.

Q: What insulation material differences exist?

A: HTMS-110-02-S-D uses Liquid Crystal Polymer (LCP) insulation, while 5-103916-2 uses Thermoplastic insulation. Both materials meet equivalent flammability standards and are suitable for board-to-board applications.

Q: Is current rating specified for both parts?

A: HTMS-110-02-S-D specifies 5A per contact. The 5-103916-2 current rating is not provided in the available specifications. Voltage rating for 5-103916-2 is specified as 30VAC; voltage rating for HTMS-110-02-S-D is not specified.
