FTS-105-04-L-DV Equivalent & Substitute Parts

Part Overview

The FTS-105-04-L-DV is a surface mount rectangular connector header manufactured by Samtec Inc., designed for board-to-board or cable applications. This 10-position, 2-row connector operates across -55°C to 125°C and carries 3.4A per contact. The part is currently active in production with full inventory availability. Substitute parts may be required due to supply constraints, design revisions, or specific application requirements such as board guide features or insulation height variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FTS-105-04-L-DV is determined by the following critical parameters:

• Pitch and Position Configuration: All substitutes maintain 0.050" (1.27mm) mating pitch and 10-position, 2-row layout
• Contact Specifications: Male pin contact type, phosphor bronze material, and 3.4A per contact current rating remain constant
• Mounting and Termination: Surface mount with solder termination is preserved across all substitutes
• Environmental Compliance: Operating temperature range (-55°C ~ 125°C), UL94 V-0 flammability rating, and ROHS3 compliance are maintained
• Insulation Material: Liquid Crystal Polymer (LCP) is consistent across all parts

Variations between the main part and substitutes are limited to:

• Insulation Height: FTS-105-04-L-DV-A and FTS-105-04-L-DV maintain 0.034" (0.86mm); FTSH-105-04-L-DV increases to 0.099" (2.51mm)
• Board Guide Feature: FTS-105-04-L-DV-A includes board guide; FTS-105-04-L-DV and FTSH-105-04-L-DV do not
• Series Designation: FTS series versus FTSH series reflects design generation

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status with ROHS3 compliance and unlimited moisture sensitivity level rating, making them suitable for equivalent substitution within the specified electrical and mechanical constraints.

FTS-105-04-L-DV-A is selected when board guide alignment features are required for automated assembly or precision positioning applications. The board guide does not alter electrical performance or thermal characteristics.

FTSH-105-04-L-DV is selected when increased insulation height of 0.099" (2.51mm) is required for clearance or mechanical design constraints. This variant belongs to the FTSH series and maintains all electrical and thermal specifications of the FTS series.

Selection between FTS-105-04-L-DV and FTS-105-04-L-DV-A depends solely on whether board guide functionality is necessary for the application. Both maintain identical insulation height and electrical ratings.

Frequently Asked Questions (FAQ)

Q: Can FTS-105-04-L-DV be directly replaced with FTS-105-04-L-DV-A?

A: Yes. Both parts share identical pitch (0.050"), position count (10), row configuration (2), contact specifications, current rating (3.4A), and operating temperature range (-55°C ~ 125°C). The only difference is the addition of a board guide feature in the FTS-105-04-L-DV-A variant. Direct substitution is possible if board guide presence does not conflict with PCB layout.

Q: What is the primary difference between FTS and FTSH series connectors?

A: The FTSH-105-04-L-DV increases insulation height to 0.099" (2.51mm) compared to 0.034" (0.86mm) in the FTS series. All other electrical, thermal, and material specifications remain identical. Selection depends on mechanical clearance requirements in the application.

Q: Are all three parts ROHS3 compliant?

A: Yes. FTS-105-04-L-DV, FTS-105-04-L-DV-A, and FTSH-105-04-L-DV are all ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity).

Q: Can FTSH-105-04-L-DV be used in applications designed for FTS-105-04-L-DV?

A: Substitution is possible only if the increased insulation height of 0.099" (2.51mm) does not violate PCB layout constraints or mating clearances. All electrical and thermal specifications are equivalent.

Q: What is the current rating per contact for all substitute parts?

A: All three parts carry 3.4A per contact with phosphor bronze contact material and gold mating finish.
