For Active Product Status: All listed substitutes maintain active product status, ensuring long-term availability and supply chain continuity compared to the obsolete 68031-136.
For Gold Contact Finish: Preci-Dip 350-10-136-00-006101, 350-10-136-00-013101, 350-10-136-01-666101, 350-V3-136-00-006101, and Samtec HMTSW-136-08-F-S-230 and HMTSW-136-08-G-S-205 provide gold-plated mating contacts, matching the original specification.
For Tin Contact Finish: Preci-Dip 350-80-136-00-006101, 350-80-136-00-013101, and 350-80-136-01-666101 offer tin-plated alternatives for cost-sensitive applications.
For Extended Operating Temperature Range: Samtec HMTSW series supports -55°C ~ 125°C, matching Preci-Dip alternatives and exceeding the TE Connectivity 8-146274-6 range of -65°C ~ 105°C.
For Square Contact Shape Matching: Samtec HMTSW-136-08-F-S-230 and HMTSW-136-08-G-S-205 maintain square contact geometry identical to the original 68031-136, while TE Connectivity 8-146274-6 also provides square contacts.
For Press-Fit Termination Option: Preci-Dip 350-10-136-01-666101, 350-80-136-01-666101 support both press-fit and solder termination, providing design flexibility.
Frequently Asked Questions (FAQ)
Q: Can I directly replace 68031-136 with any of the listed substitutes?
A: Yes, all listed substitutes share the critical functional parameters: 36 positions, 0.100" (2.54mm) pitch, male pin headers, through-hole mounting, solder termination, push-pull fastening, unshrouded design, and UL94 V-0 flammability rating. Physical board layout compatibility depends on contact length and insulation height variations, which are detailed in the parameter comparison table.
Q: What is the main difference between Preci-Dip 350-10 and 350-80 series?
A: The primary difference is contact finish. The 350-10 series uses gold-plated mating contacts, while the 350-80 series uses tin-plated mating contacts. Both series share identical pitch, position count, and mounting characteristics. Selection depends on application requirements for corrosion resistance and conductivity.
Q: Why does the original 68031-136 have a 5A current rating while substitutes are rated 3A?
A: The current rating difference reflects design variations in contact geometry and material composition. The 68031-136 uses square phosphor bronze contacts, while most substitutes use circular brass contacts. For applications requiring 5A continuous current, verify that the substitute's 3A rating meets your actual circuit requirements, as peak vs. continuous current distinctions may apply.
Q: Are Samtec HMTSW parts compatible with standard 0.100" (2.54mm) pitch receptacles?
A: Yes, Samtec HMTSW-136-08-F-S-230 and HMTSW-136-08-G-S-205 maintain the 0.100" (2.54mm) mating pitch and are compatible with standard receptacles designed for this pitch. The HMTSW series offers board-to-board or cable connection capability, providing additional application flexibility.
Q: What is the significance of the 350-V3 variant?
A: The Preci-Dip 350-V3-136-00-006101 features a mixed contact finish: gold-plated mating contacts with tin-plated posts. This configuration balances corrosion resistance at the mating interface with cost efficiency in the solder termination area.
Q: Does the TE Connectivity 8-146274-6 offer any advantages over Preci-Dip alternatives?
A: The TE Connectivity 8-146274-6 provides breakaway connector capability and maintains square contact geometry matching the original 68031-136. However, its operating temperature range (-65°C ~ 105°C) is narrower than Preci-Dip and Samtec alternatives (-55°C ~ 125°C). Inventory availability is significantly higher at 3080 pieces.
Q: Are there compliance differences between substitutes?
A: All substitutes are ROHS3 compliant or RoHS compliant, addressing the non-compliance status of the original 68031-136. Preci-Dip parts include REACH Unaffected status. All parts maintain UL94 V-0 flammability rating and EAR99 export classification.
Q: What should I consider when selecting between gold and tin contact finishes?
A: Gold-plated contacts provide superior corrosion resistance and lower contact resistance, suitable for high-reliability applications and environments with moisture or corrosive exposure. Tin-plated contacts offer cost advantages and adequate performance for standard industrial applications with controlled environmental conditions.
