Amphenol ICC 66432-016 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 66432-016 is a 16-position rectangular receptacle connector designed for IDC (Insulation Displacement Contact) termination on ribbon cable. This connector features a 0.100" pitch configuration with dual-row layout and gold-plated contacts suitable for 28-30 AWG wire applications. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations where this connector type is required.

Substitute Part Grouping Explanation

Substitution eligibility for the 66432-016 is determined by strict alignment with the following critical parameters:

Connector geometry: 16-position, dual-row configuration with 0.100" pitch and 0.100" row spacing
Termination method: IDC contact system for ribbon cable
Contact specification: Female socket, gold-plated finish
Wire compatibility: Support for 26-30 AWG ribbon cable (overlapping gauge range)
Mounting configuration: Free hanging, in-line orientation

The 3M 89116-0003 meets these substitution criteria. While the wire gauge specification differs (26-28 AWG versus 28-30 AWG), the overlap range of 26-28 AWG ensures mechanical and electrical compatibility for applications within this shared specification window.

Engineering Selection Recommendations

The 3M 89116-0003 serves as a direct functional substitute for the obsolete Amphenol ICC 66432-016. Key selection factors include:

Product Status: The 66432-016 is classified as obsolete. The 89116-0003 maintains active product status, ensuring ongoing availability and manufacturer support.

Compliance & Certifications: The 89116-0003 is ROHS3 compliant, whereas the 66432-016 is RoHS non-compliant. Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4051) classifications. Both maintain MSL 1 (Unlimited) moisture sensitivity ratings.

Wire Gauge Consideration: The 89116-0003 specifies 26-28 AWG, while the 66432-016 specifies 28-30 AWG. The overlapping range of 26-28 AWG ensures mechanical and electrical compatibility for applications utilizing wire gauges within this shared specification. Applications requiring 29-30 AWG wire must evaluate contact retention and termination force characteristics against the 89116-0003 specification.

Inventory & Availability: Both parts maintain substantial stock levels (793 and 815 units respectively), supporting immediate procurement.

Frequently Asked Questions (FAQ)

Q: Can the 3M 89116-0003 directly replace the Amphenol ICC 66432-016 in existing designs?

A: Yes, for applications using ribbon cable within the 26-28 AWG range. The connectors share identical pitch, row configuration, contact type, and mounting orientation. Applications currently using 29-30 AWG wire should evaluate the 89116-0003 contact specifications against their termination requirements.

Q: What is the significance of the wire gauge difference between these parts?

A: The 66432-016 accommodates 28-30 AWG; the 89116-0003 accommodates 26-28 AWG. The overlapping specification (26-28 AWG) defines the compatible application window. Wire gauges outside this overlap may experience different contact retention or termination force characteristics.

Q: Are there mechanical or electrical differences between these connectors?

A: No. Both connectors share identical pitch (0.100"), row spacing (0.100"), contact finish (gold at 30.0µin thickness), and IDC termination method. Mechanical and electrical performance within the overlapping wire gauge specification is equivalent.

Q: Does the RoHS compliance difference affect substitution?

A: The 89116-0003 is ROHS3 compliant while the 66432-016 is RoHS non-compliant. For new designs or applications subject to RoHS requirements, the 89116-0003 is the appropriate selection. For legacy system support where RoHS compliance is not mandated, both parts are functionally equivalent.

Q: What packaging format is available for the 3M 89116-0003?

A: The 89116-0003 is supplied in bulk packaging, as specified in the product data.
