Amphenol ICC 78299-326 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 78299-326 is a rectangular connector header featuring a right-angle, through-hole configuration with 26 positions at 2.54mm pitch. This BERGSTIK® II series connector is designed for board-to-board applications with press-fit and solder termination options. The part is currently active in production with 890 units in stock. Substitute parts are identified to address inventory availability, specific application requirements, or preferred supplier relationships while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 78299-326 is determined by strict alignment with the following critical parameters:

• Connector type classification (Header)
• Contact type (Male Pin)
• Mating pitch (0.100" / 2.54mm)
• Position count (26 positions)
• Row configuration (2 rows)
• Row spacing (0.100" / 2.54mm)
• Mounting method (Through Hole, Right Angle)
• Board-to-board style compatibility
• Unshrouded design
• Square contact geometry
• UL94 V-0 flammability compliance

The identified substitutes (TE Connectivity 1-826634-3 and 6-146310-3) meet all mandatory electrical and mechanical parameters. Variations in contact material, finish specifications, insulation material, and current ratings represent acceptable engineering tolerances within the rectangular connector category and do not preclude functional substitution in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and meet UL94 V-0 flammability requirements. The primary distinction between the main part and substitutes relates to RoHS compliance status: the 78299-326 is RoHS non-compliant, while both TE Connectivity alternatives (1-826634-3 and 6-146310-3) are ROHS3 compliant. This distinction is significant for applications subject to RoHS regulatory requirements.

The TE Connectivity 1-826634-3 offers the highest current rating at 5A and features PBT insulation material. The 6-146310-3 provides the largest available inventory (1072 units) and is supplied in tray packaging, which may offer logistical advantages for high-volume assembly operations.

Selection between substitutes should be based on regulatory compliance requirements, current capacity needs, and packaging preferences for your specific application.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-826634-3 be used as a direct replacement for the Amphenol ICC 78299-326?

A: Yes. Both parts share identical mating pitch (2.54mm), position count (26), row configuration (2 rows), mounting type (through-hole right-angle), and contact geometry (square male pins). Electrical and mechanical compatibility is established through these core parameters.

Q: What is the significance of the "Breakaway" designation on the TE Connectivity parts?

A: The breakaway feature allows individual connector positions to be separated from the main header assembly. This does not affect compatibility with standard mating connectors and represents an additional design capability rather than a limitation.

Q: Does the difference in contact material (Phosphor Bronze vs. Brass vs. Copper Alloy) affect substitution suitability?

A: Contact material differences are within acceptable engineering tolerances for rectangular connectors in this category. All materials provide adequate electrical conductivity and mechanical durability for standard board-to-board applications.

Q: Why is the 78299-326 listed as RoHS non-compliant while the substitutes are ROHS3 compliant?

A: RoHS compliance status reflects manufacturing process and material composition at the time of production. For applications requiring RoHS compliance, the TE Connectivity alternatives (1-826634-3 or 6-146310-3) are the appropriate selections.

Q: What is the difference between bulk and tray packaging?

A: Bulk packaging supplies components without organized trays, while tray packaging organizes components in structured compartments. Tray packaging (6-146310-3) typically facilitates automated assembly processes and reduces handling damage during high-volume production.

Q: Can I use the 6-146310-3 in applications requiring 5A current capacity?

A: The 6-146310-3 is rated for 3A maximum current. For applications requiring 5A capacity, the 1-826634-3 is the appropriate selection among the available substitutes.
