Engineering Selection Recommendations

The TE Connectivity 826634-5 is the primary substitute for the obsolete Amphenol ICC 78299-110. Selection is justified on the following basis:

Product Status: The 826634-5 maintains active product status with current manufacturing support, whereas the 78299-110 is obsolete. This ensures long-term availability and supply chain continuity.

Compliance: The 826634-5 is ROHS3 compliant, meeting current regulatory requirements for electronic components in most markets. The original 78299-110 is RoHS non-compliant, making the substitute the appropriate choice for new designs and updated production runs.

Mechanical Compatibility: Both parts share identical mating pitch (0.100"), position count (10), row configuration (2 rows), and right-angle through-hole mounting. Dimensional variations in contact length and insulation height are within acceptable tolerances for standard PCB footprints designed for 2.54mm pitch headers.

Electrical Compatibility: Both components feature square male pin contacts with gold mating surfaces and UL94 V-0 flammability ratings, ensuring equivalent electrical performance and safety characteristics in board-to-board applications.

Frequently Asked Questions (FAQ)

Q: Can the 826634-5 be used as a direct replacement for the 78299-110 in existing PCB designs?

A: Yes. Both parts share identical mating pitch (0.100"), position count (10), row spacing (0.100"), and right-angle through-hole mounting configuration. PCB footprints designed for the 78299-110 will accommodate the 826634-5. Minor dimensional differences in contact length and insulation height do not affect mechanical fit or electrical function.

Q: What are the key differences between these two parts?

A: The primary differences are product status, compliance, and contact material. The 826634-5 is active and ROHS3 compliant, while the 78299-110 is obsolete and RoHS non-compliant. The 826634-5 uses brass contacts versus phosphor bronze in the original part. Contact length and insulation height are slightly larger in the 826634-5. The 826634-5 offers breakaway capability, whereas the 78299-110 does not.

Q: Are there any termination differences between these parts?

A: The 78299-110 supports both press-fit and solder termination. The 826634-5 supports solder termination only. If press-fit termination is required for your application, alternative substitutes should be evaluated.

Q: What is the significance of the breakaway feature on the 826634-5?

A: The breakaway feature on the 826634-5 allows individual connector positions to be separated if needed. This does not affect compatibility with the 78299-110 footprint and provides additional flexibility for applications requiring modular connector configurations.

Q: Are the contact finishes equivalent?

A: Both parts feature gold mating surfaces. The 78299-110 specifies gold or gold GXT™ finish with 30.0µin thickness. The 826634-5 specifies gold finish with 3.90µin thickness. Both finishes provide adequate corrosion resistance and electrical conductivity for standard board-to-board applications.

Q: What is the inventory status for these parts?

A: The 78299-110 has 922 pieces in stock as new original inventory. The 826634-5 has 1560 pieces in stock as new original inventory. Given the obsolete status of the 78299-110, the 826634-5 is the recommended choice for ongoing procurement.
