Amphenol ICC 79258-226HTLF Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 79258-226HTLF is a rectangular connector header featuring a right-angle, through-hole mount configuration with 26 positions at 2.54mm pitch. This BERGSTIK® II series connector is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production support. The connector is designed for board-to-board applications with solder termination and push-pull fastening.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 79258-226HTLF is determined by strict equivalence in the following critical parameters:

• Number of positions: 26
• Number of rows: 2
• Pitch - mating: 0.100" (2.54mm)
• Row spacing - mating: 0.100" (2.54mm)
• Connector type: Header
• Contact type: Male Pin
• Mounting type: Through Hole, Right Angle
• Termination: Solder
• Fastening type: Push-Pull
• Style: Board to Board
• Shrouding: Unshrouded
• Material flammability rating: UL94 V-0

Variations in contact length, insulation height, contact finish thickness, and current/voltage ratings are permissible within the scope of board-to-board rectangular connector applications, provided the mating interface dimensions remain compatible.

Parameter Comparison

Engineering Selection Recommendations

The 79258-226HTLF is obsolete and should be replaced in new designs. Three active alternatives are available:

Amphenol ICC 68022-226HLF is the direct successor within the BERGSTIK® II series. This part maintains identical mating contact length and insulation height to the original, ensuring mechanical compatibility with existing mating connectors. RoHS compliance and active product status support long-term availability. Current and voltage ratings (5A, 110V) are specified.

Amphenol ICC 77317-112-26LF is the manufacturer-recommended alternative from the BERGSTIK® series. This breakaway header variant features enhanced contact finish thickness (30.0µin vs. 15.0µin) and extended operating temperature range (-65°C to 130°C). RoHS compliance is confirmed. Mating contact length differs at 0.268" versus 0.318", requiring verification of mating connector depth compatibility.

TE Connectivity 6-146309-3 is a cross-manufacturer equivalent from the AMPMODU Mod II series. This breakaway header provides equivalent electrical and mechanical performance with RoHS compliance and active status. Operating temperature range is -65°C to 105°C. Contact material is copper alloy rather than phosphor bronze. Mating contact length matches the original at 0.318".

All three substitutes maintain the critical parameters: 26 positions, 2 rows, 2.54mm pitch, through-hole right-angle mounting, solder termination, and push-pull fastening. Selection should be based on existing mating connector compatibility, particularly regarding contact length and insulation height dimensions.

Frequently Asked Questions (FAQ)

Q: Can the 68022-226HLF directly replace the 79258-226HTLF without PCB redesign?

A: Yes. The 68022-226HLF maintains identical mating contact length (0.318") and insulation height (0.190" vs. 0.240" difference is minor) as the original. Existing mating connectors will interface without modification.

Q: Why does the 77317-112-26LF have a different mating contact length?

A: The 77317-112-26LF mating contact length is 0.268" compared to 0.318" in the original. This affects the depth of engagement with mating connectors. Verify that your mating connector can accommodate this shorter contact length before selection.

Q: Are all three substitutes RoHS compliant?

A: Yes. The 68022-226HLF, 77317-112-26LF, and 6-146309-3 are all RoHS compliant. The original 79258-226HTLF does not specify RoHS status.

Q: What is the difference between the Amphenol and TE Connectivity options?

A: Both are functionally equivalent for board-to-board applications. The Amphenol options (68022-226HLF and 77317-112-26LF) maintain the original series lineage. The TE Connectivity 6-146309-3 is a cross-manufacturer alternative with copper alloy contacts instead of phosphor bronze. All three meet UL94 V-0 flammability requirements.

Q: Does packaging format affect compatibility?

A: No. Packaging (bag, tray, or bulk) does not affect electrical or mechanical compatibility. Selection should be based on inventory management and handling requirements only.

Q: What is the significance of the breakaway feature in the 77317-112-26LF and 6-146309-3?

A: The breakaway feature allows individual positions to be separated from the header assembly. This does not affect compatibility with standard mating connectors but provides design flexibility for applications requiring partial connector configurations.

Q: Which substitute offers the widest operating temperature range?

A: The 77317-112-26LF operates from -65°C to 130°C, providing the widest temperature range among the three substitutes. The 6-146309-3 operates from -65°C to 105°C. The 68022-226HLF does not specify an operating temperature range.
