Part Overview

The TSW-117-07-L-D-LL is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 34-position, 2-row connector operates across the temperature range of -55°C to 125°C and features gold-plated mating contacts with tin-plated solder posts. The part is Active status and ROHS3 compliant, making it suitable for modern electronic assemblies requiring board-to-board or cable interconnection.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's specifications, enabling direct replacement in applications where the core functional requirements remain constant.

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and UL94 V-0 flammability compliance, ensuring continued availability and regulatory alignment. The following considerations apply to part selection:

ROHS3 Compliance: TSW-117-07-L-D-LL and 6-146256-7 and 77313-101-34LF carry ROHS3 certification. Amphenol ICC parts (67996-134HLF, 67996-434HLF, 67997-134HLF, 67997-234HLF) are RoHS compliant but not explicitly ROHS3 certified. Applications requiring ROHS3 documentation should prioritize Samtec or TE Connectivity options.

Operating Temperature Range: The main part operates to 125°C. TE Connectivity 6-146256-7 is limited to 105°C maximum. Amphenol ICC BERGSTIK® II and BERGSTIK® parts extend to 130°C, providing additional thermal margin. Selection depends on application temperature requirements.

Contact Post Length: Variations range from 0.095" to 0.120". PCB thickness and solder joint requirements determine acceptable post length. Shorter posts (0.095") suit thinner assemblies; longer posts (0.120") accommodate thicker boards or provide additional solder volume.

Contact Finish Thickness: Mating contact gold thickness varies from 10.0µin to 100.0µin. Higher thickness (30.0µin and above) provides enhanced wear resistance for high-cycle mating applications. The main part's 10.0µin thickness is suitable for standard board-to-board connections.

Insulation Material: PBT (main part) and LCP (TE Connectivity) offer superior dimensional stability. Thermoplastic and unspecified materials in Amphenol parts remain functionally equivalent for standard applications.

Frequently Asked Questions (FAQ)

Q: Can 67996-434HLF substitute for TSW-117-07-L-D-LL?

A: 67996-434HLF meets all core electrical and mechanical requirements: 34 positions, 2 rows, 0.100" pitch, through-hole mounting, and UL94 V-0 compliance. The primary difference is tin mating contact finish versus gold on the main part. Tin finish is suitable for applications not requiring gold's corrosion resistance. Operating temperature range (-65°C to 125°C) covers the main part's specification.

Q: What is the impact of different contact post lengths?

A: Contact post length affects PCB hole engagement and solder joint formation. The main part specifies 0.100" post length. Substitute parts range from 0.095" to 0.120". Shorter posts (0.095") reduce solder volume and suit thin PCBs; longer posts (0.120") increase solder joint strength and accommodate thicker boards. PCB thickness and assembly process parameters determine acceptable variation.

Q: Are all substitute parts available in equivalent packaging?

A: Packaging differs between suppliers. TSW-117-07-L-D-LL is supplied in Bulk. TE Connectivity 6-146256-7 is Bulk. Amphenol ICC parts are supplied in Bag (67996-134HLF, 67996-434HLF, 67997-234HLF) or Bulk (67997-134HLF, 77313-101-34LF). Packaging selection impacts procurement and handling but does not affect electrical or mechanical compatibility.

Q: Why does 6-146256-7 have a lower maximum operating temperature?

A: TE Connectivity AMPMODU Mod II series 6-146256-7 is rated to 105°C maximum, compared to 125°C for the main part and 125°C to 130°C for Amphenol alternatives. Applications operating above 105°C require selection of parts with higher temperature ratings. This specification reflects the insulation material and contact design of the AMPMODU series.

Q: What is the significance of ROHS3 versus RoHS compliance?

A: ROHS3 represents the third iteration of the Restriction of Hazardous Substances directive with updated substance restrictions. Parts certified ROHS3 meet current EU regulatory requirements. RoHS-compliant parts may not include all ROHS3 restrictions. Applications subject to ROHS3 requirements should specify TSW-117-07-L-D-LL, 6-146256-7, or 77313-101-34LF.

Q: Can breakaway connector types substitute for standard headers?

A: 6-146256-7 and 77313-101-34LF are specified as Header, Breakaway types, enabling individual pin separation. Standard headers (67996 and 67997 series) do not include breakaway functionality. Breakaway capability adds design flexibility but does not prevent use in applications requiring fixed headers. Mechanical compatibility remains equivalent.
