Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 68705-208H is determined by strict adherence to the following core parameters:

Critical Parameters (Must Match):

• Connector type: Header
• Contact type: Male Pin
• Number of positions: 8
• Pitch - mating: 0.100" (2.54mm)
• Number of rows: 1
• Mounting type: Through Hole
• Termination: Solder
• Fastening type: Push-Pull
• Contact shape: Square
• Contact material: Phosphor Bronze
• Material flammability rating: UL94 V-0

Variable Parameters (Allowed to Differ):

• Contact length - post (affects overall connector height)
• Contact finish thickness - mating (affects durability)
• Contact finish - post (tin or gold)
• Insulation material (LCP or PBT acceptable)
• Insulation color (black or natural)
• RoHS compliance status
• Packaging format (bulk or bag)

All seven substitute parts listed meet the critical parameter requirements and are therefore electrically and mechanically compatible with the 68705-208H.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are electrically and mechanically compatible with the 68705-208H based on matching critical parameters. Selection among substitutes depends on specific application requirements:

For RoHS3 Compliance Requirements: All Samtec substitutes (HTSW-108-07-G-S, HTSW-108-07-S-S, TS-108-G-AA, TSW-108-07-F-S, TSW-108-08-F-S, TSW-108-09-G-S, TSW-108-12-G-S, TSW-108-23-F-S) are ROHS3 compliant, whereas the 68705-208H is RoHS non-compliant.

For Contact Post Length Selection: Choose based on PCB thickness and application stack-up requirements. The 68705-208H has a 0.095" (2.41mm) post length. Samtec equivalents range from 0.100" (2.54mm) to 0.700" (17.78mm), allowing accommodation of various board thicknesses and stacking configurations.

For Contact Finish Thickness: The 68705-208H specifies 15.0µin (0.38µm) mating contact finish. HTSW-108-07-S-S provides the thickest mating finish at 30.0µin (0.76µm) for enhanced durability. TSW series parts offer thinner finishes at 3.00µin (0.076µm) for cost optimization.

For Insulation Material: HTSW series uses Liquid Crystal Polymer (LCP), while TSW series uses Polybutylene Terephthalate (PBT). Both materials meet UL94 V-0 flammability requirements and are suitable for standard through-hole applications.

For Operating Temperature Range: All Samtec substitutes specify -55°C ~ 125°C operating temperature, providing defined thermal performance. The 68705-208H does not specify operating temperature limits.

For Inventory Availability: HTSW-108-07-G-S offers the highest stock level at 5425 units, followed by TSW-108-07-F-S at 4348 units, providing supply chain flexibility.

Frequently Asked Questions (FAQ)

Q: Are all listed substitute parts directly interchangeable with the 68705-208H?

A: Yes. All substitute parts match the critical electrical and mechanical parameters: 8-position header, 0.100" (2.54mm) pitch, male pin contacts, through-hole mounting, solder termination, push-pull fastening, square contact shape, phosphor bronze material, and UL94 V-0 flammability rating. Differences in contact post length, insulation material, and contact finish thickness do not affect functional compatibility.

Q: What is the significance of contact post length variation among substitutes?

A: Contact post length determines the overall connector height and affects compatibility with specific PCB thicknesses and board stacking configurations. The 68705-208H has a 0.095" (2.41mm) post. Samtec substitutes range from 0.100" to 0.700", allowing selection based on application requirements. Longer posts accommodate thicker PCBs or multiple stacked boards.

Q: Why do some substitutes have different insulation materials (LCP vs. PBT)?

A: Both Liquid Crystal Polymer (LCP) and Polybutylene Terephthalate (PBT) meet the UL94 V-0 flammability requirement and are suitable for standard through-hole connector applications. Material selection reflects manufacturer design choices and does not affect electrical performance or mechanical compatibility.

Q: What is the difference between gold and tin contact finish on the post?

A: Gold-finished posts (HTSW-108-07-G-S, TSW-108-09-G-S, TSW-108-12-G-S) provide enhanced corrosion resistance and are preferred for long-term storage or high-reliability applications. Tin-finished posts (HTSW-108-07-S-S, TSW-108-07-F-S, TSW-108-08-F-S, TSW-108-23-F-S) are cost-effective alternatives suitable for standard applications with normal handling and storage conditions.

Q: How does RoHS3 compliance affect part selection?

A: The 68705-208H is RoHS non-compliant, while all Samtec substitutes are ROHS3 compliant. If your application or supply chain requires RoHS3 compliance, any of the Samtec substitutes are acceptable replacements. RoHS3 compliance restricts hazardous substances and is increasingly required in regulated industries.

Q: What is the difference between bulk and bag packaging?

A: Bulk packaging (68705-208H, TSW-108-09-G-S, TSW-108-12-G-S) is typically used for high-volume orders and offers cost advantages. Bag packaging (HTSW-108-07-G-S, HTSW-108-07-S-S, TSW-108-07-F-S, TSW-108-08-F-S, TSW-108-23-F-S) provides individual unit protection and is suitable for smaller orders or applications requiring component traceability.

Q: Can I use a substitute with a longer contact post length if my application requires it?

A: Yes. Longer contact posts do not affect electrical compatibility. TSW-108-12-G-S with a 0.700" (17.78mm) post length can accommodate applications requiring extended post length for thicker PCBs or specific board configurations. Ensure mechanical clearance and board layout accommodate the increased connector height.

Q: Are all substitutes rated for the same operating temperature range?

A: All Samtec substitutes specify -55°C ~ 125°C operating temperature. The 68705-208H does not specify operating temperature limits. If your application requires defined thermal performance, Samtec substitutes provide explicit temperature ratings suitable for industrial and commercial environments.

Q: What is Moisture Sensitivity Level (MSL) and why does it vary?

A: MSL indicates the maximum time a component can be exposed to ambient moisture before soldering. MSL 1 (Unlimited) means no moisture sensitivity restrictions. TS-108-G-AA and TSW-108-07-F-S are listed as Not Applicable, indicating no moisture sensitivity concerns. All parts are suitable for standard manufacturing environments.
