FTS-122-04-L-D Equivalent & Substitute Parts

Part Overview

The FTS-122-04-L-D is an active rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board or cable applications. This 44-position, 2-row connector operates across -55°C to 125°C and features gold-plated mating contacts with tin-plated posts. The part is ROHS3 compliant and carries a UL94 V-0 flammability rating. Substitute parts are identified when electrical and mechanical parameters align within the allowed specifications for this connector category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FTS-122-04-L-D is determined by strict alignment of the following critical parameters:

• Connector type (Header, Cuttable)
• Contact type (Male Pin)
• Number of positions (44) and rows (2)
• Pitch specifications (0.050" mating pitch, 0.050" row spacing)
• Mounting type (Through Hole)
• Termination method (Solder)
• Contact finish specifications (Gold mating, Tin post)
• Operating temperature range (-55°C ~ 125°C)
• Current rating (3.4A per Contact)
• Insulation material (Liquid Crystal Polymer)
• Compliance certifications (ROHS3, UL94 V-0)

The FTSH-122-04-L-D qualifies as a substitute based on matching all critical electrical and mechanical parameters. Variations in overall contact length and insulation height do not affect functional compatibility within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both FTS-122-04-L-D and FTSH-122-04-L-D are active products from Samtec Inc. with identical electrical specifications and compliance certifications. Selection between these parts depends on physical envelope requirements within the application. The FTS-122-04-L-D features a lower profile with 0.034" insulation height and 0.274" overall contact length. The FTSH-122-04-L-D provides increased insulation height of 0.099" and overall contact length of 0.339". Both parts maintain ROHS3 compliance and UL94 V-0 flammability rating. Inventory availability should be evaluated based on project timeline requirements.

Frequently Asked Questions (FAQ)

Q: Can FTSH-122-04-L-D replace FTS-122-04-L-D in existing designs?

A: Substitution is electrically and mechanically valid based on matching pitch, position count, contact type, current rating, and operating temperature. Physical envelope differences (insulation height and overall contact length) must be evaluated against PCB layout and mating connector specifications.

Q: What are the key differences between these parts?

A: The primary differences are overall contact length (0.274" vs 0.339") and insulation height (0.034" vs 0.099"). All electrical parameters, contact finishes, materials, and compliance certifications are identical.

Q: Are both parts ROHS3 compliant?

A: Yes, both FTS-122-04-L-D and FTSH-122-04-L-D are ROHS3 compliant with UL94 V-0 flammability rating.

Q: What is the current rating for each contact?

A: Both parts are rated for 3.4A per contact across the full operating temperature range of -55°C to 125°C.

Q: Do these connectors support the same mating pitch?

A: Yes, both parts feature 0.050" (1.27mm) mating pitch and 0.050" row spacing, ensuring compatibility with standard 1.27mm pitch receptacles.
