Key Parameters

Substitute Part Grouping Explanation

Substitution of the Amphenol ICC 66900-344 is determined by the following critical parameters:

• Connector Type & Position Count: Both main and substitute parts must be 44-position receptacles to maintain mechanical and electrical compatibility with existing mating connectors.
• Pitch & Row Configuration: The 0.100" pitch and 2-row layout are fundamental to physical fit and signal integrity.
• Cable Termination Method: IDC termination is required for ribbon cable compatibility.
• Wire Gauge Compatibility: The substitute part accepts 26-28 AWG wire, which overlaps with the main part's 28-30 AWG specification, allowing connection of 28 AWG ribbon cables to both connectors.
• Contact Finish & Plating: Gold or gold-palladium finishes provide equivalent electrical performance and corrosion resistance.
• Mounting Configuration: Free hanging in-line mounting ensures identical installation requirements.

The TE Connectivity AMP Connectors 1-1658622-3 meets all substitution criteria within these defined parameters.

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 1-1658622-3 is the designated substitute for the obsolete Amphenol ICC 66900-344. Selection of this substitute is based on:

• Mechanical Compatibility: Identical pitch, row configuration, and mounting type ensure direct physical replacement without redesign.
• Electrical Compatibility: Matching contact finish thickness and feed-through design maintain signal integrity and current-carrying capacity.
• Product Status: The substitute is active and in production, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: The substitute achieves ROHS3 compliance, meeting current environmental and safety standards for new designs and procurement.
• Wire Gauge Overlap: The 26-28 AWG specification of the substitute accommodates 28 AWG ribbon cable, the common wire gauge within both specifications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-1658622-3 directly replace the Amphenol ICC 66900-344 in existing assemblies?

A: Yes. Both connectors share identical pitch (0.100"), row configuration (2 rows), position count (44), and mounting type (free hanging in-line). The mechanical and electrical interfaces are equivalent.

Q: What is the wire gauge compatibility between these two connectors?

A: The Amphenol ICC 66900-344 accepts 28-30 AWG ribbon cable. The TE Connectivity 1-1658622-3 accepts 26-28 AWG ribbon cable. Both connectors accommodate 28 AWG cable, which is the overlapping specification. For applications using 29-30 AWG cable, the original Amphenol connector is required.

Q: Does the contact finish difference affect electrical performance?

A: No. Both connectors specify 30.0µin (0.76µm) contact finish thickness. The TE Connectivity substitute offers gold or gold-palladium finish, both of which provide equivalent corrosion resistance and electrical conductivity to the gold finish of the original part.

Q: Why is the TE Connectivity part listed as the manufacturer-recommended substitute?

A: The TE Connectivity 1-1658622-3 meets all critical substitution parameters: identical connector type, position count, pitch, row spacing, mounting configuration, and IDC termination method. Additionally, it is an active product with current production status and regulatory compliance, addressing the obsolescence of the original part.

Q: Are there any packaging or inventory considerations?

A: The TE Connectivity 1-1658622-3 is supplied in bulk packaging with 7553 units in stock. The original Amphenol part has 923 units available but is obsolete. For new procurement, the TE Connectivity substitute is the recommended choice.
