Substitute Part Grouping Explanation

Substitution eligibility for the FTS-111-02-F-D is determined by strict equivalence across the following critical parameters:

Connector type: Header, Cuttable
Contact type: Male Pin
Number of positions: 22
Number of rows: 2
Pitch - mating: 0.050" (1.27mm)
Row spacing - mating: 0.050" (1.27mm)
Mounting type: Through Hole
Termination: Solder
Current rating: 3.4A per Contact
Operating temperature range: -55°C ~ 125°C
Material flammability rating: UL94 V-0

Engineering Selection Recommendations

Both FTS-111-02-F-D and FTSH-111-02-F-D are active production parts from Samtec Inc. with identical RoHS3 compliance and UL94 V-0 flammability certification. Selection between these parts is based on dimensional requirements specific to the application. The FTS-111-02-F-D features a lower insulation height (0.034") and shorter overall contact length (0.199"), while the FTSH-111-02-F-D provides increased insulation height (0.099") and overall contact length (0.265"). Both maintain equivalent electrical performance across the specified current and temperature operating ranges. Part selection should be determined by PCB layout constraints and mating connector geometry requirements.

Frequently Asked Questions (FAQ)

Q: Can FTSH-111-02-F-D be used as a direct replacement for FTS-111-02-F-D?

A: Both parts share identical electrical specifications, connector type, contact configuration, and pitch. The primary difference is dimensional: insulation height and overall contact length. Direct substitution is possible only if the application accommodates the dimensional variations. PCB layout and mating connector clearances must be evaluated.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution requires equivalence in connector type (Header, Cuttable), contact type (Male Pin), position count (22), row configuration (2 rows), pitch (0.050"), row spacing (0.050"), mounting method (Through Hole), termination (Solder), current rating (3.4A per Contact), and operating temperature range (-55°C to 125°C).

Q: Are there compliance differences between FTS-111-02-F-D and FTSH-111-02-F-D?

A: Both parts are RoHS3 compliant and carry UL94 V-0 flammability certification. No compliance differences exist between the two parts.

Q: What is the inventory status for substitute parts?

A: FTS-111-02-F-D has 955 units in stock. FTSH-111-02-F-D has 866 units in stock. Both are available as new original parts in tube packaging.

Q: How do the dimensional differences affect connector mating?

A: The mating contact length (0.075") is identical for both parts. The difference in overall contact length and insulation height affects the connector's profile above the PCB and the engagement depth with mating connectors. Application-specific PCB layout and connector cavity depth must accommodate these variations.
