Amphenol ICC 68705-236 Equivalent & Substitute Parts
Part Overview
The Amphenol ICC 68705-236 is a rectangular connector header for through-hole mounting with 36 positions at 0.100" (2.54mm) pitch. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support, board redesigns, and production continuity. The BERGSTIK® II series connector provides board-to-board connectivity with unshrouded, push-pull fastening and solder termination. Identifying compatible substitutes ensures design flexibility while maintaining electrical and mechanical compatibility.

Engineering Selection Recommendations
All substitute parts listed are active products with ROHS3 compliance, providing superior long-term availability and regulatory alignment compared to the obsolete, non-compliant 68705-236.
Samtec HTSW Series (HTSW-136-26-TM-S): This part offers the closest electrical and mechanical compatibility with tin mating finish and LCP insulation material. Operating temperature range of -55°C to 105°C covers standard industrial applications. Recommended for direct replacement in new designs requiring active product support.
Sullins PBC and PEC Series (PBC36SAAN, PBC36SABN, PEC36SAAN, PEC36SABN): These breakaway header variants provide flexible post length options (0.120" or 0.230") to accommodate different PCB stack-up requirements. PBC series features gold mating finish; PEC series features tin mating finish. Both series support extended operating temperature range of -65°C to 125°C. PBT insulation material provides robust mechanical properties.
Sullins PGC Series (PGC36SAAN): Offers gold finish on both mating and post contacts with copper alloy material. Suitable for applications requiring enhanced contact durability and conductivity. Thermoplastic polyester insulation provides alternative material composition.
Samtec TSW Series (TSW-136-07-F-S, TSW-136-09-G-S, TSW-136-09-T-S, TSW-136-10-G-S): These classic PCB header strips provide variable post length options (0.100" to 0.500") for specialized mounting configurations. TSW-136-07-F-S and TSW-136-09-G-S feature gold finish; TSW-136-09-T-S features tin finish. Operating temperature ranges from -55°C to 125°C (or -55°C to 105°C for tin variant). Phosphor bronze contact material with PBT insulation ensures reliable performance.
Selection Criteria:
- For direct replacement with minimal design changes: HTSW-136-26-TM-S
- For extended temperature applications: PBC36SAAN, PBC36SABN, PEC36SAAN, PEC36SABN
- For gold contact finish preference: PBC36SAAN, PBC36SABN, PGC36SAAN, TSW-136-09-G-S, TSW-136-10-G-S
- For tin contact finish preference: HTSW-136-26-TM-S, PEC36SAAN, PEC36SABN, TSW-136-09-T-S
- For custom post length requirements: TSW series variants
Frequently Asked Questions (FAQ)
Q: Can I use any of these substitute parts as a direct drop-in replacement for the 68705-236?
A: All listed substitute parts share the same 36-position, 0.100" pitch configuration and through-hole solder termination. However, variations in contact post length (ranging from 0.095" to 0.500") may require PCB design verification. Consult your PCB stack-up specifications and connector mating depth requirements before final selection.
Q: What is the primary difference between the Samtec and Sullins substitute options?
A: Samtec parts (HTSW and TSW series) offer variable post length configurations and are available with tin or gold mating finishes. Sullins parts (PBC, PEC, PGC series) provide breakaway header options with consistent post length variants and are available with gold or tin finishes. Both manufacturers provide ROHS3-compliant, active products with extended operating temperature ranges.
Q: Why do some substitute parts have longer post lengths than the original 68705-236?
A: Post length variations accommodate different PCB thicknesses and stacking requirements. The original part specifies 0.095" post length; substitutes range from 0.100" to 0.500". Select post length based on your specific PCB assembly configuration. Longer posts provide additional solder joint engagement; shorter posts suit thin PCB applications.
Q: Are all substitute parts RoHS compliant?
A: Yes. All listed substitute parts carry ROHS3 compliance status, whereas the original 68705-236 is RoHS non-compliant. This compliance improvement supports modern supply chain requirements and environmental regulations.
Q: What contact finish should I select: gold or tin?
A: Gold finishes (10.0µin thickness) provide superior corrosion resistance and are preferred for applications with extended shelf life or harsh environments. Tin finishes (100.0µin thickness) offer cost efficiency and adequate performance for standard industrial applications. Both finishes meet UL94 V-0 flammability requirements.
Q: Can I mix substitute parts from different manufacturers in the same design?
A: Yes, provided all parts meet the mandatory matching parameters: 36 positions, 0.100" pitch, male pin contacts, through-hole solder termination, push-pull fastening, and UL94 V-0 rating. Verify mechanical compatibility with your connector housing and mating interface specifications.
Q: What is the difference between breakaway and non-breakaway header variants?
A: Breakaway headers (PBC and PEC series) feature perforated insulation allowing individual pin removal for custom configurations. Non-breakaway headers (HTSW, TSW, PGC series) maintain solid insulation throughout. Select based on your assembly and customization requirements.
Q: Which substitute part offers the best long-term availability?
A: All listed parts are classified as active products with established manufacturing and distribution networks. Samtec and Sullins are primary connector manufacturers with consistent product availability. For critical applications, consult with your distributor regarding inventory levels and lead times.
