Frequently Asked Questions (FAQ)

Q: Can I substitute the TE Connectivity 104655-9 with a Samtec TFM-140 series connector?

A: Yes. Both part families meet the critical substitution parameters: 80 positions, 2 rows, 0.050" (1.27mm) pitch, surface mount, shrouded 4-wall design, solder termination, and LCP insulation. The Samtec TFM series provides enhanced current rating (2.9A vs. 0.5A per contact) and voltage rating (275VAC), making it suitable for higher-power applications. All TFM variants are ROHS3 compliant and active products.

Q: What is the difference between TFM-140-02-L-D and TFM-140-02-S-D?

A: The primary difference is the contact finish thickness on the mating surface. TFM-140-02-L-D features 15.0µin (0.38µm) gold finish, while TFM-140-02-S-D features 30.0µin (0.76µm) gold finish. The thicker finish on the S-D variant provides enhanced durability for high-cycle mating applications. Both parts are functionally equivalent for standard applications.

Q: What does the "-LC" suffix indicate in part numbers like TFM-140-02-L-D-LC?

A: The "-LC" suffix indicates board lock functionality. This feature provides mechanical retention between the header and mating connector, preventing accidental disconnection. The 104655-9 also includes board lock, making TFM-140-02-L-D-LC and TFM-140-02-S-D-LC direct functional equivalents in this regard.

Q: Can I use TFML-140 series connectors as substitutes for the 104655-9?

A: TFML-140 series connectors are functionally equivalent for 80-position, 1.27mm pitch applications. The primary difference is the fastening mechanism: TFML uses friction lock instead of push-pull. Friction lock provides retention through mechanical interference rather than a locking lever. This substitution is valid only if the mating connector is also friction lock compatible.

Q: What is the significance of the "-K-TR" suffix in TFM-140-02-S-D-K-TR?

A: The "-K-TR" suffix indicates tape & reel packaging with pick-and-place compatibility. This packaging format is optimized for automated assembly processes. The "K" denotes the specific tape configuration, and "TR" indicates tape & reel format. This variant is suitable for high-volume manufacturing environments.

Q: Are all substitute parts ROHS3 compliant?

A: All Samtec TFM and TFML series substitutes listed are ROHS3 compliant. The original TE Connectivity 104655-9 is RoHS non-compliant. The TE Connectivity 5-104655-9 variant is ROHS3 compliant but is discontinued at DiGi Electronics. For new designs requiring RoHS compliance, Samtec substitutes are the recommended choice.

Q: What is the operating temperature difference between the 104655-9 and Samtec substitutes?

A: The 104655-9 operates from -65°C to 105°C. Samtec TFM and TFML series operate from -55°C to 125°C. The Samtec parts provide a wider high-temperature range (20°C higher maximum) but a narrower low-temperature range (10°C higher minimum). For applications requiring -65°C operation, the 104655-9 or 5-104655-9 must be used.

Q: Can I mix 104655-9 headers with Samtec TFM-140 receptacles in the same assembly?

A: No. Connector compatibility requires matching both the header and receptacle from the same manufacturer series. The 104655-9 header mates with TE Connectivity AMP receptacles. Samtec TFM headers mate with Samtec TFM receptacles. Cross-manufacturer mating is not supported.

Q: What packaging options are available for the substitute parts?

A: Samtec TFM and TFML series are available in multiple packaging formats: Tube (standard), Tape & Reel (TR), Cut Tape (CT), and Bulk. The packaging selection depends on manufacturing volume and assembly automation requirements. Tube packaging is suitable for low-to-medium volume applications, while Tape & Reel is optimized for high-volume automated pick-and-place assembly.

Q: Is the contact shape difference (circular vs. square) significant for substitution?

A: The contact shape difference between the 104655-9 (circular contacts) and Samtec TFM series (square contacts) does not affect electrical or mechanical compatibility with properly designed mating receptacles. Both contact geometries provide equivalent contact pressure and signal integrity when mated with corresponding receptacle designs. The shape difference is a manufacturing variation within the same functional category.
