Engineering Selection Recommendations

All listed substitute parts maintain active product status, ensuring ongoing availability and manufacturer support. The primary distinction between substitutes is contact length on the post side, which accommodates varying PCB thicknesses and application depth requirements.

For applications requiring RoHS compliance: All substitute parts listed (8-146274-6, HTSW-136-26-TM-S, PGC36SAAN, TSW series) are RoHS3 compliant, providing regulatory advantage over the original obsolete 68031-336.

For applications with extended temperature requirements: TSW-136-07-F-S, TSW-136-09-G-S, TSW-136-10-G-S, and TSW-136-11-G-S support -55°C to 125°C operating range, exceeding the original specification.

For applications with standard temperature range: HTSW-136-26-TM-S and TSW-136-09-T-S support -55°C to 105°C, meeting typical industrial requirements.

For applications requiring higher current capacity: The original 68031-336 specifies 5A current rating. Substitute parts with specified current ratings (8-146274-6 and PGC36SAAN at 3A) may require verification against application requirements. TSW series parts with unspecified current ratings should be evaluated against application load specifications.

For contact finish selection: Gold-plated contacts (TSW-136-09-G-S, TSW-136-10-G-S, TSW-136-11-G-S, TSW-136-07-F-S, PGC36SAAN) provide enhanced corrosion resistance. Tin-plated contacts (TSW-136-09-T-S, TSW-136-10-T-S, 8-146274-6, HTSW-136-26-TM-S) offer cost efficiency for standard applications.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the 68031-336?

A: Substitution requires matching the core connector specifications: 36 positions, 0.100" (2.54mm) pitch, male pin contacts, through-hole solder termination, push-pull fastening, square contact shape, and UL94 V-0 flammability rating. Contact length on the post side may vary to accommodate different PCB thicknesses.

Q: Can I use a substitute part with a different contact finish?

A: Yes. The original 68031-336 specifies gold or gold GXT™ finish. Substitute parts with tin or alternative gold finishes maintain electrical compatibility. Contact finish selection should be based on application corrosion environment and cost considerations.

Q: Are all substitute parts pin-compatible with the original 68031-336?

A: Yes. All listed substitutes maintain the 36-position, 2.54mm pitch configuration and square contact geometry, ensuring mechanical and electrical compatibility with existing mating connectors and PCB layouts designed for the 68031-336.

Q: What is the difference between the various TSW-136 variants?

A: TSW-136 variants differ primarily in contact length on the post side, ranging from 0.100" (TSW-136-07-F-S) to 0.900" (TSW-136-13-F-S). Selection depends on PCB thickness and application depth requirements. Contact finish varies between gold and tin options.

Q: Why do some substitute parts have lower current ratings than the original?

A: The original 68031-336 specifies 5A current rating. Some substitutes (8-146274-6 and PGC36SAAN) specify 3A. Application current requirements must be verified against the selected substitute. TSW series parts with unspecified current ratings require evaluation based on contact material and wire gauge used in the application.

Q: Is RoHS compliance important for my application?

A: The original 68031-336 is RoHS non-compliant. All listed substitutes are RoHS3 compliant. If your application or supply chain requires RoHS compliance, any substitute part provides regulatory advantage. Verify compliance requirements with your procurement or quality department.

Q: Can I mix substitute parts in the same design?

A: All substitute parts are mechanically and electrically compatible with the 68031-336 footprint. However, for design consistency and supply chain management, using a single substitute part number across a product is recommended.

Q: What operating temperature range should I select?

A: The original 68031-336 does not specify operating temperature. Samtec TSW series parts support -55°C to 125°C (gold finish variants) or -55°C to 105°C (tin finish variants). TE Connectivity 8-146274-6 supports -65°C to 105°C. Select based on your application's thermal environment.
