FTS-118-03-F-D Equivalent & Substitute Parts

Part Overview

The FTS-118-03-F-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This vertical mount connector features 36 positions arranged in 2 rows with 0.050" (1.27mm) pitch spacing. The part is currently active in production with full inventory availability. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when design flexibility permits component selection from equivalent specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FTS-118-03-F-D is determined by strict equivalence across the following critical parameters:

• Connector type (Header, Cuttable)
• Contact type (Male Pin)
• Number of positions (36)
• Number of rows (2)
• Pitch spacing (0.050" / 1.27mm mating and row spacing)
• Mounting type (Through Hole)
• Termination method (Solder)
• Contact material (Phosphor Bronze)
• Insulation material (Liquid Crystal Polymer)
• Operating temperature range (-55°C ~ 125°C)
• Current rating (3.4A per Contact)
• Compliance certifications (UL94 V-0, ROHS3)

The FTSH-118-03-F-D meets all these criteria and qualifies as a direct substitute. Variations in overall contact length and insulation height do not affect functional compatibility in applications where the connector footprint and mating interface are the primary design constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the FTS-118-03-F-D and FTSH-118-03-F-D are active production parts from Samtec Inc. with identical compliance certifications (UL94 V-0, ROHS3 Compliant). The primary difference between these parts is the overall contact length and insulation height. The FTS-118-03-F-D features a shorter profile (0.189" overall contact length, 0.034" insulation height), while the FTSH-118-03-F-D provides an extended profile (0.255" overall contact length, 0.099" insulation height).

Selection between these parts depends on PCB stackup requirements and available board space. Both parts maintain identical electrical performance, mating pitch, contact force characteristics, and thermal ratings. Component selection should be based on mechanical fit within the target application's physical constraints.

Frequently Asked Questions (FAQ)

Q: Can FTSH-118-03-F-D replace FTS-118-03-F-D in existing designs?

A: Electrical and functional compatibility is confirmed. However, the FTSH-118-03-F-D has a taller profile (0.255" vs 0.189" overall contact length). PCB layout and stackup clearances must be verified before substitution.

Q: What is the significance of the series designation change (FTS vs FTSH)?

A: The series designation reflects the physical profile difference. Both series share identical mating pitch, contact configuration, and electrical specifications. The FTSH designation indicates the extended insulation height variant.

Q: Are the contact finishes identical between these parts?

A: Yes. Both parts feature gold-plated mating contacts (3.00µin thickness) and tin-plated posts, ensuring equivalent signal integrity and solderability.

Q: Do both parts support the same current rating?

A: Yes. Both FTS-118-03-F-D and FTSH-118-03-F-D are rated for 3.4A per contact across the full operating temperature range of -55°C to 125°C.

Q: What packaging format is used for both parts?

A: Both parts are supplied in tube packaging for automated assembly compatibility.
