Engineering Selection Recommendations

Active Product Availability: All identified substitute parts maintain active product status with current manufacturing support. The original TE Connectivity 103675-3 is classified as obsolete, making transition to an active equivalent necessary for ongoing procurement and supply chain continuity.

Compliance Considerations: Amphenol ICC (FCI) parts 67996-134HLF, 67996-234HLF, and 75844-304-34LF are designated as RoHS Compliant, providing regulatory alignment for applications subject to RoHS requirements. The Samtec TSW-117-07-L-D is ROHS3 Compliant. The original TE part is RoHS non-compliant. Selection should account for regulatory requirements of the target application.

Certification and Standards: All substitute parts maintain UL94 V-0 material flammability rating and MSL 1 (Unlimited) moisture sensitivity classification, matching the original part's safety and environmental specifications.

Contact Finish and Material Composition: Substitute parts employ phosphor bronze contact material with either gold or tin finish options. The original part uses copper alloy with gold mating finish. Phosphor bronze provides equivalent electrical and mechanical performance for standard interconnection applications.

Thermal Operating Range: Substitute parts specify operating temperature ranges of -55°C to -65°C minimum and 125°C to 130°C maximum. The original part does not specify operating temperature limits. Selection should confirm thermal requirements align with application environment.

Inventory Availability: Current stock levels for substitute parts range from 661 to 1280 units, providing immediate availability for design transitions and production requirements.

Frequently Asked Questions (FAQ)

Q: What determines whether a part can substitute for the TE Connectivity 103675-3?

A: Primary substitution criteria include matching pitch (0.100" / 2.54mm), position count (34), row configuration (2 rows), row spacing (0.100" / 2.54mm), contact type (male pin), mounting method (through hole), termination (solder), fastening mechanism (push-pull), contact shape (square), and shrouding (unshrouded). All listed substitute parts meet these core requirements.

Q: Are there differences in contact post length among the substitute options?

A: Yes. Contact post lengths vary: 67996-134HLF and 67996-234HLF feature 0.095" (2.41mm) posts; 67997-734HLF and 68692-434HLF feature 0.100" to 0.120" (2.54mm to 3.05mm) posts; 75844-304-34LF features 0.300" (7.62mm) posts; TSW-117-07-L-D features 0.100" (2.54mm) posts. The original part specifies 0.120" (3.05mm) posts. Post length affects PCB hole depth requirements and should be verified against board design specifications.

Q: What is the difference between BERGSTIK® II and BERGSTIK® series parts?

A: BERGSTIK® II represents the current generation of Amphenol's BERGSTIK connector line with active product status. BERGSTIK® (75844-304-34LF) represents the earlier generation. Both series maintain compatible pitch and position configurations. BERGSTIK® II parts offer enhanced specifications and continued manufacturing support.

Q: How does the number of positions loaded affect substitution?

A: The original TE part specifies 31 of 34 positions loaded. All Amphenol and Samtec substitutes specify all 34 positions loaded. This difference indicates the original part was supplied with three unloaded contact positions. Substitute parts provide full position loading, which is compatible with applications using fewer than 34 active connections.

Q: What is the significance of contact finish composition differences?

A: The original part specifies gold mating finish on copper alloy contacts. Substitute parts offer gold or tin mating finishes on phosphor bronze contacts. Gold finish provides superior corrosion resistance and lower contact resistance. Tin finish is suitable for standard industrial applications. Selection should align with application environment and electrical performance requirements.

Q: Are the Amphenol and Samtec parts interchangeable in the same connector housing?

A: All substitute parts maintain identical pitch (0.100" / 2.54mm), position count (34), and row spacing (0.100" / 2.54mm), ensuring mechanical compatibility with mating connectors designed for the original TE part. Electrical performance differences relate to contact material and finish composition rather than physical interface geometry.

Q: What does RoHS compliance status indicate for part selection?

A: RoHS compliance indicates the part meets Restriction of Hazardous Substances regulations, restricting lead, cadmium, mercury, and other hazardous materials. The original TE part is RoHS non-compliant. Amphenol parts 67996-134HLF, 67996-234HLF, and 75844-304-34LF are RoHS Compliant. Samtec TSW-117-07-L-D is ROHS3 Compliant. Applications subject to RoHS requirements should select compliant alternatives.

Q: How do operating temperature ranges compare among substitutes?

A: Amphenol BERGSTIK® II parts (67996-134HLF, 67996-234HLF) specify -65°C to 125°C. Amphenol BERGSTIK® II parts (67997-734HLF, 68692-434HLF) and BERGSTIK® (75844-304-34LF) specify -65°C to 130°C. Samtec TSW-117-07-L-D specifies -55°C to 125°C. The original part does not specify operating temperature. Selection should confirm the substitute's thermal range accommodates the application environment.

Q: What packaging options are available for substitute parts?

A: Amphenol parts are supplied in Bag or Bulk packaging. Samtec TSW-117-07-L-D is supplied in Bag packaging. Packaging selection affects handling, storage, and inventory management but does not affect electrical or mechanical performance.
