Amphenol ICC 79257-224HTLF Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 79257-224HTLF is an active rectangular connector header designed for through-hole, right-angle board-to-board applications. This unshrouded, 24-position connector operates across -65°C to 130°C and is RoHS compliant with UL94 V-0 flammability rating. Finding equivalent substitute parts is necessary when primary inventory is unavailable, when alternative packaging formats are required, or when design flexibility permits component standardization across product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 79257-224HTLF is determined by strict alignment of core electrical and mechanical parameters. The following criteria establish functional equivalence:

Critical Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (24)
• Number of rows (2)
• Pitch - mating (0.100" / 2.54mm)
• Row spacing - mating (0.100" / 2.54mm)
• Mounting type (Through Hole, Right Angle)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Style (Board to Board or Board to Board/Cable)
• Shrouding (Unshrouded)

The TE Connectivity AMP Connectors part number 1-826634-2 meets all critical matching parameters and qualifies as a direct substitute within the rectangular connector 24-position 2.54mm pitch category.

Parameter Comparison

Engineering Selection Recommendations

Both the 79257-224HTLF and 1-826634-2 are active products with equivalent core functionality for 24-position, 2.54mm pitch rectangular connector applications. Selection between these parts should be based on the following engineering considerations:

79257-224HTLF (Amphenol ICC BERGSTIK® II) is appropriate when:

• Operating temperature range of -65°C to 130°C is required
• Phosphor bronze contact material is specified
• Tube packaging is preferred for inventory management
• Maximum operating temperature exceeds 105°C

1-826634-2 (TE Connectivity AMPMODU Mod II) is appropriate when:

• Higher current rating (5A vs 3A) is beneficial
• Breakaway connector capability adds design flexibility
• Bulk packaging aligns with procurement processes
• Operating temperature range of -65°C to 105°C is acceptable
• PBT insulation material meets application requirements

Both parts maintain UL94 V-0 flammability compliance, RoHS compliance status, and unlimited moisture sensitivity level (MSL 1). Physical dimension variations exist in contact length and insulation height; verify PCB layout compatibility before substitution.

Frequently Asked Questions (FAQ)

Q: Can 1-826634-2 directly replace 79257-224HTLF in existing designs?

A: Direct replacement is possible when the operating temperature requirement does not exceed 105°C and the slightly larger contact dimensions (0.264" mating length vs 0.230") do not create PCB layout conflicts. Verify mating connector compatibility and insulation height clearance before implementation.

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

A: The primary differences are operating temperature range (79257-224HTLF: -65°C to 130°C; 1-826634-2: -65°C to 105°C), current rating (3A vs 5A), contact material (phosphor bronze vs brass), and packaging format (tube vs bulk). Both maintain identical pitch, position count, and mounting configuration.

Q: Are there packaging considerations when substituting between these parts?

A: Yes. The 79257-224HTLF is supplied in tube packaging, while 1-826634-2 is supplied in bulk packaging. Procurement, storage, and handling procedures may differ. Verify that bulk packaging meets your supply chain requirements.

Q: Do both connectors meet the same compliance standards?

A: Both parts are RoHS compliant (79257-224HTLF: RoHS Compliant; 1-826634-2: ROHS3 Compliant), UL94 V-0 rated, and have MSL 1 moisture sensitivity level. Both are active products with equivalent regulatory status for rectangular connector applications.

Q: What should be verified before substituting 1-826634-2 for 79257-224HTLF?

A: Verify operating temperature requirements do not exceed 105°C, confirm PCB layout accommodates the slightly larger insulation height (0.219" vs 0.190"), ensure mating connector compatibility with the breakaway header design, and validate that the 5A current rating meets or exceeds application requirements.
