Substitute Part Grouping Explanation

Substitute parts for the FTS-113-02-FM-D are qualified based on the following critical parameters that determine functional interchangeability:

Connector type (Header, Cuttable)
Contact type (Male Pin)
Pitch spacing (0.050" / 1.27mm)
Position count (26 positions)
Row configuration (2 rows)
Row spacing (0.050" / 1.27mm)
Mounting method (Through Hole)
Termination type (Solder)
Current rating (3.4A per Contact)
Operating temperature range (-55°C ~ 125°C)
Contact finish (Gold mating surface)
Contact material (Phosphor Bronze)
Insulation material (Liquid Crystal Polymer)
Flammability rating (UL94 V-0)
RoHS compliance (ROHS3)

The identified substitutes maintain these core parameters while allowing variation in physical dimensions (Overall Contact Length and Insulation Height) that do not affect electrical performance or mating compatibility.

Engineering Selection Recommendations

All three parts—FTS-113-02-FM-D, FTSH-113-02-F-D, and FTS-113-02-F-D—are active production components from Samtec Inc. with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts is determined by physical envelope requirements:

FTS-113-02-FM-D and FTS-113-02-F-D share identical overall contact length (0.199" / 5.05mm) and insulation height (0.034" / 0.86mm), differing only in fastening type designation. FTSH-113-02-F-D provides increased overall contact length (0.265" / 6.73mm) and insulation height (0.099" / 2.51mm), suitable for applications requiring extended post engagement or greater insulation standoff.

All parts maintain identical electrical performance: 3.4A per contact current rating, -55°C to 125°C operating temperature, gold-plated mating contacts, and phosphor bronze contact material. Component selection should be based on PCB layout constraints and mating depth requirements specific to the target application.

Frequently Asked Questions (FAQ)

Q: Can FTS-113-02-FM-D be directly replaced with FTSH-113-02-F-D?

A: Direct replacement is possible from an electrical standpoint, as both parts share identical contact type, pitch, position count, current rating, and operating temperature. However, the FTSH variant has greater overall contact length (0.265" vs 0.199") and insulation height (0.099" vs 0.034"), which may affect PCB layout compatibility. Physical clearance verification is required before substitution.

Q: What is the difference between FTS-113-02-FM-D and FTS-113-02-F-D?

A: These parts are electrically and mechanically identical. Both feature 0.199" overall contact length and 0.034" insulation height. The designation difference reflects fastening type classification within Samtec's product nomenclature but does not affect functional performance or mating compatibility.

Q: Are all three parts RoHS compliant?

A: Yes. FTS-113-02-FM-D, FTSH-113-02-F-D, and FTS-113-02-F-D are all ROHS3 compliant and carry UL94 V-0 flammability certification.

Q: What determines whether a substitute part is compatible?

A: Compatibility is determined by matching connector type, contact type, pitch spacing (0.050"), position count (26), row configuration (2 rows), row spacing (0.050"), mounting method (through hole), termination type (solder), current rating (3.4A per contact), and operating temperature range (-55°C to 125°C). Physical dimensions may vary if PCB layout permits.

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

A: Yes. All three parts are rated for -55°C to 125°C operating temperature, supporting applications within this thermal envelope.
