Engineering Selection Recommendations

All identified substitute parts maintain active product status and comply with RoHS requirements, ensuring regulatory compliance and long-term availability. Selection among substitute options is determined by specific application constraints:

67996-134HLF (Amphenol ICC BERGSTIK® II): This substitute provides extended operating temperature capability to 125°C and maintains the 3A per contact current rating specification. The phosphor bronze contact material with gold finish offers enhanced corrosion resistance compared to the tin-finished copper alloy of the primary part. The slightly reduced post length (0.095" versus 0.120") accommodates thinner PCB stack-up configurations. This option is suitable for applications requiring higher thermal performance within standard board-to-board spacing.

TSW-117-07-F-D (Samtec TSW Series): This substitute extends operating temperature to 125°C and features phosphor bronze contacts with gold finish. The post length of 0.100" provides intermediate stack-up accommodation. The PBT insulation material and ROHS3 compliance support modern manufacturing standards. This option is appropriate for applications requiring enhanced contact durability and thermal performance.

TSW-117-07-L-D (Samtec TSW Series): This substitute offers identical electrical and mechanical specifications to TSW-117-07-F-D with the highest inventory availability (1280 units). The gold contact finish with 10.0µin thickness and phosphor bronze material provide reliable long-term performance. This option is recommended for high-volume applications requiring extended operating temperature range and proven contact reliability.

TSW-117-08-G-D-LL (Samtec TSW Series): This substitute features kinked pin termination in addition to solder termination, providing enhanced mechanical retention during assembly. The extended post length of 0.200" accommodates thicker PCB stack-up configurations. Gold finish on both mating and post surfaces ensures consistent contact performance. This option is suitable for applications requiring mechanical strain relief or thicker board assemblies.

TSW-117-10-S-D (Samtec TSW Series): This substitute provides the longest post length (0.500") for applications requiring maximum PCB stack-up accommodation or extended board separation. The gold contact finish with 30.0µin thickness and phosphor bronze material deliver robust contact performance. This option is specified for applications with significant board-to-board spacing or multiple stacked connector configurations.

Frequently Asked Questions (FAQ)

Q: Can the 6-146254-7 be directly replaced with any of the listed substitutes without PCB redesign?

A: Direct replacement depends on post length compatibility with your PCB stack-up. The 6-146254-7 features a 0.120" post length. Substitutes with 0.095" (67996-134HLF) or 0.100" (TSW-117-07-F-D, TSW-117-07-L-D) posts accommodate thinner stacks. Substitutes with 0.200" (TSW-117-08-G-D-LL) or 0.500" (TSW-117-10-S-D) posts require thicker board assemblies. Verify your specific stack-up thickness before selection.

Q: What is the difference between tin and gold contact finishes in these connectors?

A: The 6-146254-7 uses tin finish (100.0µin thickness) on copper alloy contacts. All substitute parts use gold finish on phosphor bronze contacts with varying thicknesses (3.00µin to 30.0µin). Gold provides superior corrosion resistance and lower contact resistance over extended service life, particularly in environments with temperature cycling or moisture exposure. Tin finish is suitable for controlled indoor environments with moderate thermal cycling.

Q: Are all substitute parts compatible with the same mating connectors as the 6-146254-7?

A: Yes. All substitute parts maintain identical mating pitch (0.100"), row spacing (0.100"), position count (34), and contact geometry (square male pins). Mating compatibility is preserved across all substitutes. However, verify that your mating connector accommodates the specific post length of your selected substitute.

Q: What is the significance of the operating temperature range differences?

A: The 6-146254-7 operates from -65°C to 105°C. The Amphenol ICC 67996-134HLF extends the upper limit to 125°C. All Samtec TSW substitutes operate from -55°C to 125°C, providing higher maximum temperature capability but a slightly higher minimum temperature limit. For applications requiring -65°C operation, the 6-146254-7 or 67996-134HLF are required. For applications limited to -55°C minimum, all Samtec options are suitable.

Q: How do packaging differences (Bulk versus Bag) affect component selection?

A: The 6-146254-7 is supplied in Bulk packaging. Samtec TSW-117-07-F-D and TSW-117-07-L-D are supplied in Bag packaging, while TSW-117-08-G-D-LL and TSW-117-10-S-D are supplied in Bulk. Bag packaging typically includes individual component wrapping for moisture protection during storage. Bulk packaging requires proper moisture control during inventory management. Select based on your receiving, storage, and assembly process requirements.

Q: What does the kinked pin termination on TSW-117-08-G-D-LL provide compared to standard solder termination?

A: Kinked pin termination includes a mechanical bend in the post that provides additional strain relief and mechanical retention during PCB assembly and thermal cycling. This feature reduces stress on solder joints and improves reliability in applications subject to vibration or repeated thermal expansion and contraction. Standard solder termination relies solely on the solder joint for mechanical retention.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 6-146254-7 is RoHS Compliant. The Amphenol ICC 67996-134HLF is RoHS Compliant. All Samtec TSW substitutes are ROHS3 Compliant, which represents the current RoHS directive revision. All parts meet regulatory requirements for lead-free manufacturing and hazardous substance restrictions.

Q: What is the current rating difference between the 6-146254-7 and substitute parts?

A: The 6-146254-7 specifies 3A current rating. The Amphenol ICC 67996-134HLF specifies 3A per contact. The Samtec TSW substitutes do not provide explicit current rating specifications in the available data. For applications requiring confirmed current capacity, the 6-146254-7 or 67996-134HLF are recommended. Contact Samtec directly for TSW series current rating specifications if required for your application.

Q: How does contact material affect long-term reliability?

A: The 6-146254-7 uses copper alloy contacts with tin finish. All substitute parts use phosphor bronze contacts with gold finish. Phosphor bronze provides superior spring characteristics and fatigue resistance compared to copper alloy. Gold finish resists oxidation and corrosion more effectively than tin, particularly in environments with temperature cycling, humidity, or corrosive atmospheres. For applications requiring extended service life or harsh environmental conditions, phosphor bronze with gold finish is preferred.
