Amphenol ICC 77319-803-10 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 77319-803-10 is a through-hole, right-angle rectangular connector header with 10 positions at 2.54mm pitch, designed for board-to-board applications. This part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement. The BERGSTIK® series connector provides solder termination with push-pull fastening and gold-plated mating contacts suitable for standard PCB assembly processes.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector headers is determined by strict alignment of electrical and mechanical parameters. The following criteria establish functional equivalence:

Primary Matching Criteria:

• Connector type (Header, Breakaway)
• Contact type (Male Pin)
• Pitch - Mating (0.100" / 2.54mm)
• Number of positions (10)
• Number of rows (2)
• Row spacing - Mating (0.100" / 2.54mm)
• Mounting type (Through Hole, Right Angle)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Contact shape (Square)
• Insulation material category (Thermoplastic)
• Flammability rating (UL94 V-0)

Secondary Considerations:

• Contact finish composition and thickness
• Insulation height and color
• Operating temperature range
• Current rating
• Product status and compliance certifications

All identified substitutes maintain identical primary matching criteria with the main part number 77319-803-10.

Parameter Comparison

Engineering Selection Recommendations

77319-803-10LF (Direct Amphenol ICC Substitute): This part represents the direct successor within the BERGSTIK® series from the original manufacturer. It maintains identical mechanical dimensions and contact specifications while offering active product status and RoHS compliance. The LF designation indicates lead-free termination processing. Operating temperature range extends to 130°C with a 3A current rating. This substitute is the preferred choice for designs requiring continuity with the original Amphenol ICC platform and where RoHS compliance is mandated.

826664-5 (TE Connectivity MFR Recommended Alternative): This part provides cross-manufacturer compatibility from TE Connectivity's AMPMODU Mod II series. While maintaining all critical pitch, position, and mounting specifications, it introduces minor dimensional variations in contact length and insulation height. The contact material differs (brass versus phosphor bronze), and gold plating thickness is reduced. Operating temperature is limited to 105°C with a higher 5A current rating. This substitute is suitable for applications where TE Connectivity platform standardization is preferred and dimensional tolerances accommodate the specified variations. RoHS compliance is confirmed.

Both substitutes maintain UL94 V-0 flammability certification and unlimited moisture sensitivity rating. Selection between them depends on manufacturer platform preference and specific thermal or current requirements of the application.

Frequently Asked Questions (FAQ)

Q: Can 77319-803-10LF be used as a direct replacement for 77319-803-10?

A: Yes. The 77319-803-10LF maintains identical connector type, pitch, position count, row configuration, mounting orientation, and contact specifications. The primary differences are product status (active versus obsolete), RoHS compliance, and extended operating temperature range to 130°C. Mechanical and electrical compatibility is confirmed.

Q: What are the key differences between 77319-803-10LF and 826664-5?

A: Both parts share identical pitch (2.54mm), position count (10), row configuration (2), and mounting type (through-hole right-angle). Differences include: manufacturer (Amphenol ICC versus TE Connectivity), contact material (phosphor bronze versus brass), contact finish thickness (15.0µin versus 3.90µin mating side), insulation material (thermoplastic versus PBT), insulation height (0.248" versus 0.219"), contact post length (0.115" versus 0.126"), operating temperature range (-65°C to 130°C versus -65°C to 105°C), and current rating (3A versus 5A). Both maintain UL94 V-0 flammability and RoHS compliance.

Q: Is the 826664-5 suitable for high-temperature applications?

A: The 826664-5 operates to a maximum of 105°C. For applications requiring operation above 105°C, the 77319-803-10LF with its 130°C upper temperature limit is the appropriate selection.

Q: Are there packaging differences between these substitutes?

A: The 77319-803-10 original part does not specify packaging. Both 77319-803-10LF and 826664-5 are supplied in bulk packaging. Verify packaging requirements with your procurement specification.

Q: Do all three parts meet RoHS compliance requirements?

A: The original 77319-803-10 is RoHS non-compliant. Both 77319-803-10LF and 826664-5 are RoHS compliant, making them suitable for applications with RoHS mandates.

Q: What is the significance of the "LF" designation in 77319-803-10LF?

A: The LF designation indicates lead-free termination processing, which aligns with RoHS compliance requirements and modern manufacturing standards.
