FTSH-109-02-L-DV Equivalent & Substitute Parts

Part Overview

The FTSH-109-02-L-DV is a surface mount rectangular connector header manufactured by Samtec Inc., designed for board-to-board or cable applications. This 18-position connector operates across -55°C to 125°C and features a 0.050" (1.27mm) pitch with gold-plated mating contacts rated at 3.4A per contact. The part is Active status and ROHS3 compliant, making it suitable for current production applications. Substitute parts may be required due to inventory constraints, design revisions, or specific feature requirements such as board guide integration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FTSH-109-02-L-DV is determined by strict alignment of the following critical parameters:

• Pitch - Mating: 0.050" (1.27mm)
• Number of Positions: 18
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Contact Type: Male Pin
• Mounting Type: Surface Mount
• Termination: Solder
• Contact Finish - Mating: Gold
• Current Rating: 3.4A per Contact
• Operating Temperature: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The identified substitute parts maintain these core electrical and mechanical parameters. Variations in insulation height, series designation, and optional features such as board guides do not affect functional interchangeability within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance, ensuring suitability for current production designs. The FTSH-109-02-L-DV and FTSH-109-02-L-DV-A share identical insulation height specifications (0.099" / 2.51mm), while the FTS-109-02-L-DV features a reduced insulation height of 0.034" (0.86mm). The FTSH-109-02-L-DV-A includes a board guide feature not present in the other variants. Selection should be based on PCB layout requirements, available inventory, and specific mechanical constraints of the application.

Frequently Asked Questions (FAQ)

Q: Can FTS-109-02-L-DV be used as a direct replacement for FTSH-109-02-L-DV?

A: FTS-109-02-L-DV is electrically and mechanically compatible based on pitch, position count, row spacing, contact type, and current rating. The primary difference is insulation height: FTS-109-02-L-DV measures 0.034" (0.86mm) versus 0.099" (2.51mm) for FTSH-109-02-L-DV. Verify PCB clearance and mating connector compatibility before substitution.

Q: What is the significance of the board guide feature in FTSH-109-02-L-DV-A?

A: The board guide feature provides mechanical alignment assistance during assembly. This does not affect electrical performance or current rating. Selection depends on assembly process requirements and PCB design specifications.

Q: Are all three parts RoHS compliant?

A: Yes, all three parts are ROHS3 compliant and suitable for applications requiring RoHS certification.

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

A: All three parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: Do these connectors support the same operating temperature range?

A: Yes, all three parts operate across -55°C to 125°C and maintain UL94 V-0 flammability rating across this range.
