Substitute Part Grouping Explanation

Substitute parts for the FTS-114-03-F-D are determined by strict equivalence across the following critical parameters:

• Connector type classification (Header, Cuttable)
• Contact type (Male Pin)
• Position count and row configuration (28 positions, 2 rows)
• Mating pitch and row spacing (0.050" / 1.27mm)
• Mounting method (Through Hole)
• Termination type (Solder)
• Contact material and finish specifications (Phosphor Bronze, Gold mating surface, Tin post)
• Insulation material (Liquid Crystal Polymer)
• Operating temperature range (-55°C ~ 125°C)
• Current rating per contact (3.4A)
• Compliance certifications (UL94 V-0, ROHS3)

Substitution is valid when all these parameters match between the main part and candidate substitute. Variations in overall contact length, insulation height, or inventory levels do not affect functional equivalence for standard board-to-board interconnect applications.

Parameter Comparison

Engineering Selection Recommendations

Both the FTS-114-03-F-D and FTSH-114-03-F-D maintain active product status with full manufacturing support. Both parts comply with ROHS3 regulations and carry UL94 V-0 flammability certification, meeting standard industrial and commercial application requirements.

The primary distinction between these parts is the overall contact length and insulation height. The FTS-114-03-F-D provides a more compact profile (0.189" overall contact length, 0.034" insulation height), while the FTSH-114-03-F-D offers an extended profile (0.255" overall contact length, 0.099" insulation height). Selection between these equivalents depends on available PCB clearance and mating connector depth requirements. Both parts are electrically and mechanically interchangeable for standard 28-position, 1.27mm-pitch header applications.

Frequently Asked Questions (FAQ)

Q: Are FTS-114-03-F-D and FTSH-114-03-F-D fully interchangeable?

A: These parts are functionally equivalent for electrical and mechanical interconnect purposes. Both feature identical contact pitch (0.050" / 1.27mm), position count (28), row configuration (2 rows), contact material (Phosphor Bronze), and current rating (3.4A per contact). The difference in overall contact length and insulation height may affect physical fit in space-constrained applications. Verify PCB clearance and mating connector depth before substitution.

Q: What determines substitution eligibility for this connector series?

A: Substitution is valid when the candidate part matches all critical parameters: 28-position, 2-row configuration; 0.050" mating pitch and row spacing; male pin contact type; through-hole solder termination; Phosphor Bronze contact material with gold mating finish; Liquid Crystal Polymer insulation; -55°C to 125°C operating range; and 3.4A per-contact current rating.

Q: Can these connectors be used in high-temperature applications?

A: Both parts are rated for -55°C to 125°C continuous operation. Applications requiring sustained temperatures above 125°C require alternative connector designs with higher thermal ratings.

Q: Are these parts suitable for automated assembly?

A: Both FTS-114-03-F-D and FTSH-114-03-F-D are through-hole solder-terminated connectors compatible with standard wave soldering and selective soldering processes. The cuttable header design allows customization of position count for specific board layouts.

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

A: The series designation indicates the connector family within Samtec's product line. FTS and FTSH represent different mechanical profiles within the same electrical specification family. The FTSH variant provides extended contact length and insulation height compared to the FTS variant.
