Engineering Selection Recommendations

Primary Recommendation: 68405-102HLF

The 68405-102HLF from Amphenol ICC (FCI) is the direct functional equivalent of the 78299-102. This part maintains identical core electrical and mechanical specifications while offering active product status and RoHS compliance. The contact length post variation (0.095" versus 0.120") is within acceptable tolerance for board stack height applications. This part is the preferred choice for designs requiring minimal redesign and maximum compatibility with existing layouts.

Secondary Recommendations: Samtec HTSW Series

The Samtec HTSW-101 series (HTSW-101-08-F-D-RA, HTSW-101-09-F-D-NA, HTSW-101-11-F-D-RA, HTSW-101-22-S-D-RA) provides alternative solutions with enhanced specifications. All variants are active products with ROHS3 compliance and specified operating temperature ranges (-55°C ~ 125°C). Selection within this series depends on required contact post length:

HTSW-101-08-F-D-RA: 0.090" post length (closest to original 0.120")
HTSW-101-22-S-D-RA: 0.190" post length (matches original insulation height)
HTSW-101-09-F-D-NA: 0.309" post length (extended post for deeper board penetration)
HTSW-101-11-F-D-RA: 0.490" post length (maximum post length for specialized applications)

All Samtec variants feature Liquid Crystal Polymer (LCP) insulation material and tin-plated post finishes, providing enhanced environmental resistance compared to the original specification.

Frequently Asked Questions (FAQ)

Q: Can the 68405-102HLF directly replace the 78299-102 without PCB modification?

A: The 68405-102HLF maintains all critical mating and mounting dimensions. The contact post length difference (0.095" versus 0.120") affects board stack height by 0.025". PCB modification is required only if the original design relied on the specific post length for mechanical alignment or if solder joint depth is critical to the application.

Q: What is the primary difference between the Amphenol 68405-102HLF and Samtec HTSW series substitutes?

A: The 68405-102HLF maintains the same manufacturer lineage and insulation height (0.190") as the original 78299-102. Samtec HTSW parts feature increased insulation height (0.240") and LCP insulation material. The choice depends on whether the original board layout accommodates the 0.050" height increase and whether enhanced environmental specifications are required.

Q: Are all substitute parts RoHS compliant?

A: The 68405-102HLF is RoHS Compliant. All Samtec HTSW variants are ROHS3 Compliant. The original 78299-102 is RoHS non-compliant. Compliance status must be verified against specific application requirements and regional regulations.

Q: Which substitute part has the closest physical footprint to the original 78299-102?

A: The 68405-102HLF provides the closest physical match, with identical insulation height (0.190") and minimal post length variation (0.025" difference). This part requires the least PCB redesign effort.

Q: Can Samtec HTSW parts be used in applications originally designed for the 78299-102?

A: Samtec HTSW parts are mechanically and electrically compatible with the original design. The increased insulation height (0.240" versus 0.190") and variable post lengths require verification against PCB layout constraints. Contact length mating (0.230") and row spacing (0.100") are identical, ensuring mating compatibility.

Q: What is the significance of contact post length variation among the Samtec HTSW options?

A: Contact post length determines how deeply the connector penetrates the PCB and affects solder joint formation. Shorter posts (0.090") provide minimal penetration; longer posts (0.309" to 0.490") accommodate thicker PCBs or provide mechanical support for high-vibration applications. Selection must align with PCB thickness and mechanical requirements.

Q: Are there packaging differences between the substitute parts?

A: The 68405-102HLF is supplied in Bulk packaging. Samtec HTSW variants have packaging specifications listed as not provided in the available data. Confirm packaging requirements with the supplier for production planning.

Q: What operating temperature range should be specified for the substitute parts?

A: The original 78299-102 does not specify an operating temperature range. The 68405-102HLF also does not specify a range. All Samtec HTSW variants specify -55°C ~ 125°C. If the application requires temperature specification, Samtec parts provide documented performance across this range.
