Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FTM-109-02-F-DV are identified based on the following critical parameters that determine functional and mechanical compatibility:

• Pitch - Mating: 0.039" (1.00mm) — must match exactly for PCB footprint compatibility
• Number of Positions: 18 — connector capacity requirement
• Number of Rows: 2 — physical layout configuration
• Row Spacing - Mating: 0.039" (1.00mm) — inter-row distance for mating alignment
• Contact Type: Male Pin — gender compatibility
• Mounting Type: Surface Mount — assembly process compatibility
• Termination: Solder — connection method
• Insulation Material: Liquid Crystal Polymer (LCP) — material specification
• Contact Finish - Mating: Gold — electrical contact performance

The BC050-18A-K0-0200-0160-0480-LB from GCT meets these core substitution criteria. Variations in contact length, insulation height, current rating, operating temperature range, and contact finish thickness do not preclude substitution when the primary functional parameters align.

Parameter Comparison

Engineering Selection Recommendations

Both the FTM-109-02-F-DV and BC050-18A-K0-0200-0160-0480-LB are Active product status connectors with ROHS3 compliance and MSL 1 rating. Selection between these parts should be based on application-specific requirements:

The FTM-109-02-F-DV supports a higher current rating of 2.8A per contact and operates across a wider temperature range (-55°C to 125°C), making it suitable for high-current or extended temperature applications.

The BC050-18A-K0-0200-0160-0480-LB provides a specified voltage rating of 250VAC/DC and operates within -40°C to 105°C, appropriate for standard industrial and commercial applications within this temperature envelope.

Both parts share identical pitch, position count, row configuration, and insulation material specifications, ensuring PCB footprint and mating compatibility.

Frequently Asked Questions (FAQ)

Q: Can BC050-18A-K0-0200-0160-0480-LB be used as a direct replacement for FTM-109-02-F-DV?

A: Yes, for applications where the operating temperature range of -40°C to 105°C and current rating of 1A per contact are acceptable. The critical parameters—pitch, position count, row spacing, contact type, mounting type, and insulation material—are identical, ensuring mechanical and electrical compatibility at the PCB level.

Q: What are the differences in contact length between these parts?

A: The FTM-109-02-F-DV has a mating contact length of 0.075" (1.90mm), while the BC050-18A-K0-0200-0160-0480-LB has 0.079" (2.00mm). This 0.004" difference is within typical connector tolerance ranges and does not affect mating compatibility.

Q: Are there packaging differences between these parts?

A: Yes. The FTM-109-02-F-DV is supplied in Tube packaging, while the BC050-18A-K0-0200-0160-0480-LB is supplied in Tape & Reel (TR) format. This affects handling and assembly processes but does not impact electrical or mechanical performance.

Q: Which part should be selected for high-temperature applications?

A: The FTM-109-02-F-DV is rated for -55°C to 125°C operation, making it the appropriate choice for applications requiring extended temperature range coverage beyond the BC050-18A-K0-0200-0160-0480-LB's -40°C to 105°C specification.

Q: What is the current-carrying capacity difference?

A: The FTM-109-02-F-DV supports 2.8A per contact, while the BC050-18A-K0-0200-0160-0480-LB supports 1A per contact. For high-current applications, the FTM-109-02-F-DV is the appropriate selection.
