Engineering Selection Recommendations

All substitute parts listed maintain active product status and meet the core electrical and mechanical requirements for 36-position, 0.100" pitch through-hole header applications. Selection among substitutes should be based on the following criteria:

RoHS Compliance: The original 68418-436H is RoHS non-compliant. All substitute parts (TE Connectivity 8-146274-6 and all Samtec TSW-136 variants) are RoHS compliant or ROHS3 compliant, making them suitable for applications requiring regulatory compliance.

Contact Finish: Tin-plated variants (TSW-136-09-T-S, TSW-136-10-T-S, TSW-136-22-T-S) match the original part's mating surface finish. Gold-plated variants (TSW-136-09-G-S, TSW-136-10-G-S, TSW-136-11-G-S, TSW-136-23-SM-S) provide enhanced corrosion resistance and are suitable for high-reliability applications.

Post Length Variations: Post lengths range from 0.115" (TSW-136-23-SM-S) to 0.600" (TSW-136-11-G-S). Selection depends on PCB thickness and solder joint requirements. The original 68418-436H and TSW-136-09 variants share 0.400" post length, providing direct mechanical compatibility.

Operating Temperature: Samtec TSW-136 parts rated to -55°C ~ 125°C (gold-plated variants) or -55°C ~ 105°C (tin-plated variants) exceed typical requirements. TE Connectivity 8-146274-6 operates from -65°C ~ 105°C.

Insulation Material: TE Connectivity 8-146274-6 uses liquid crystal polymer (LCP), while Samtec variants use polybutylene terephthalate (PBT). Both materials meet UL94 V-0 flammability requirements.

Frequently Asked Questions (FAQ)

Q: Can TSW-136-09-G-S directly replace 68418-436H in existing designs?

A: Yes. TSW-136-09-G-S shares identical mating pitch (0.100"), position count (36), contact length (0.230" mating / 0.400" post), and overall contact length (0.730"). The primary difference is gold plating on mating contacts versus tin, which provides superior corrosion resistance without affecting electrical compatibility.

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

A: Tin-plated contacts (TSW-136-09-T-S, TSW-136-10-T-S, TSW-136-22-T-S) match the original 68418-436H finish and are suitable for standard applications. Gold-plated contacts (TSW-136-09-G-S, TSW-136-10-G-S, TSW-136-11-G-S, TSW-136-23-SM-S) provide enhanced corrosion resistance and lower contact resistance, recommended for high-reliability or high-frequency applications.

Q: How do post length variations affect PCB compatibility?

A: Post length determines solder joint depth. The 68418-436H and TSW-136-09 variants feature 0.400" posts suitable for standard PCB thicknesses (0.062"). Longer posts (TSW-136-10 at 0.500", TSW-136-11 at 0.600") accommodate thicker PCBs or provide additional solder volume. Shorter posts (TSW-136-22 at 0.300", TSW-136-23-SM-S at 0.115") are for thin PCBs or surface-mount applications.

Q: Is TE Connectivity 8-146274-6 compatible with 68418-436H?

A: 8-146274-6 is electrically compatible but has dimensional differences. Mating contact length is 0.318" (versus 0.230"), post length is 0.125" (versus 0.400"), and insulation height is 0.090" (versus 0.100"). These variations may affect mechanical fit in existing connectors or PCB layouts designed for the original part.

Q: What is the significance of RoHS compliance for substitute selection?

A: The original 68418-436H is RoHS non-compliant. All listed substitutes are RoHS or ROHS3 compliant, meeting EU Directive 2011/65/EU requirements. For new designs or applications subject to RoHS regulations, compliant substitutes are mandatory.

Q: Are all substitute parts available in equivalent quantities?

A: Inventory levels vary. TE Connectivity 8-146274-6 has 3,080 units in stock. Samtec TSW-136 variants range from 652 to 1,132 units. Availability should be confirmed for production requirements.

Q: Can Samtec TSW-136 variants be intermixed in the same application?

A: Samtec TSW-136 variants share identical mating pitch, position count, and contact geometry, allowing intermixing within the same connector interface. However, post length differences affect PCB solder joint characteristics and should be standardized within a single assembly to ensure consistent mechanical performance.
