Amphenol ICC 79258-226HT Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 79258-226HT is a rectangular connector header, right-angle configuration, with 26 positions at 2.54mm pitch. This through-hole, board-to-board connector features male pins with solder termination and push-pull fastening. The part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 79258-226HT is determined by strict alignment of the following core parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 26
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Shape: Square
• Material Flammability Rating: UL94 V-0
• Insulation Color: Black
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Both identified substitute parts meet these core substitution criteria. Variations in contact length, insulation height, contact finish thickness, and compliance status are secondary parameters that may influence selection based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The 79258-226HT is obsolete; both substitute parts are active and available. Selection between substitutes depends on compliance and application requirements:

68022-226HLF (Amphenol ICC) maintains the same manufacturer and BERGSTIK® II series lineage. This part is RoHS compliant and provides 5A current rating at 110V. The insulation height is increased to 0.240" (6.10mm) compared to the original 0.190" (4.83mm), and contact post length is reduced to 0.110" (2.79mm). This substitute is suitable for applications requiring RoHS compliance within the Amphenol ICC product ecosystem.

6-146309-3 (TE Connectivity) is a cross-manufacturer substitute from the AMPMODU Mod II series. This part is RoHS compliant and offers a wider operating temperature range of -65°C to 105°C. The contact finish thickness on the mating surface is doubled to 30.0µin (0.76µm), and the insulation material is specified as thermoplastic, glass-filled. The current rating is 3A. This substitute is suitable for applications requiring extended temperature performance and cross-manufacturer flexibility.

Both substitutes meet the core mechanical and electrical substitution criteria. Selection should be based on compliance requirements, thermal environment, and supply chain preferences.

Frequently Asked Questions (FAQ)

Q: Can the 68022-226HLF directly replace the 79258-226HT?

A: Yes, the 68022-226HLF meets all core substitution parameters: 26-position, 2-row, 2.54mm pitch, right-angle through-hole header with solder termination and push-pull fastening. The increased insulation height and reduced post length are secondary dimensional variations. Verify PCB layout compatibility before implementation.

Q: What is the primary difference between the two substitute parts?

A: The 68022-226HLF is from Amphenol ICC (same manufacturer as the original) and maintains the BERGSTIK® II series designation. The 6-146309-3 is from TE Connectivity and belongs to the AMPMODU Mod II series. Both are RoHS compliant and functionally equivalent for the core connector interface.

Q: Does the increased insulation height of the 68022-226HLF affect PCB compatibility?

A: The insulation height increases from 0.190" (4.83mm) to 0.240" (6.10mm). This may affect clearance in confined spaces or adjacent component placement. Verify PCB layout and mechanical envelope before substitution.

Q: What is the significance of the contact finish thickness difference in the 6-146309-3?

A: The 6-146309-3 provides 30.0µin (0.76µm) gold plating on the mating surface, compared to 15.0µin (0.38µm) on both the original and the 68022-226HLF. Thicker plating may provide enhanced durability in high-cycle mating applications, though both thicknesses meet standard connector specifications.

Q: Are there packaging considerations when ordering substitutes?

A: The 68022-226HLF is supplied in bag packaging, while the 6-146309-3 is supplied in tray packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Which substitute is recommended for new designs?

A: Both substitutes are active and RoHS compliant. For continuity within the Amphenol ICC ecosystem, select 68022-226HLF. For designs requiring extended operating temperature range (-65°C to 105°C), select 6-146309-3. Consult application requirements and supply chain strategy.
