Equivalent & Substitute Parts for 66432-110

Part Overview

The Amphenol ICC 66432-110 is a 10-position rectangular receptacle connector designed for IDC (Insulation Displacement Contact) termination with ribbon cable. This connector features a 0.100" pitch, dual-row configuration, and gold-plated contacts rated for 28-30 AWG wire gauges. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 66432-110 is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Position count (10)
• Pitch and row spacing (0.100")
• IDC termination method
• Gold contact finish
• Free hanging mounting configuration

The substitute parts listed below meet these core electrical and mechanical requirements. Wire gauge compatibility is evaluated within acceptable ranges for IDC contact systems.

Parameter Comparison

Engineering Selection Recommendations

3-1437020-9 (TE Connectivity AMP-Latch): This part maintains full electrical and mechanical equivalence to the 66432-110 with identical wire gauge specification (28-30 AWG) and contact finish thickness. The part is currently in active production status, ensuring long-term availability. RoHS compliance status matches the original part. This substitute is the primary choice for direct replacement applications.

89110-0103 (3M 891 Series): This part meets all core connector specifications and is actively produced. The wire gauge range (26-28 AWG) is narrower than the original specification but remains compatible with IDC termination systems designed for this connector class. This part achieves ROHS3 compliance, providing an advantage for applications subject to environmental regulations. The gray housing color differs from the original blue, which may be relevant for visual identification in legacy systems.

Frequently Asked Questions (FAQ)

Q: Can the 3M 89110-0103 be used in place of the 66432-110 if my application uses 28 AWG ribbon cable?

A: Yes. The 89110-0103 supports 26-28 AWG wire gauges, which includes 28 AWG within its specified range. The IDC contact system and pitch specifications are identical, ensuring mechanical and electrical compatibility for this wire gauge.

Q: What is the significance of the wire gauge difference between the TE Connectivity and 3M substitutes?

A: The 66432-110 and 3-1437020-9 both specify 28-30 AWG, while the 89110-0103 specifies 26-28 AWG. The 3M part does not support 30 AWG termination. Selection depends on the actual wire gauge used in your application. If 30 AWG ribbon cable is required, use the TE Connectivity part.

Q: Does the RoHS compliance difference affect substitution?

A: The 66432-110 and 3-1437020-9 are both RoHS non-compliant. The 89110-0103 is ROHS3 compliant. Selection should align with your system's regulatory requirements. If RoHS3 compliance is mandatory, the 3M part is the appropriate choice.

Q: Are the housing colors interchangeable?

A: The 66432-110 and 3-1437020-9 both feature blue housing, while the 89110-0103 has gray housing. From an electrical standpoint, color is not a functional parameter. However, in systems where visual identification or color-coding is used for circuit tracing or documentation, housing color differences should be noted.

Q: What is the MSL rating and why is it the same across all three parts?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life with no special moisture control requirements during storage or handling. All three parts share this rating, meaning no additional precautions are necessary for any of these substitutes.
