Amphenol ICC 66245-350 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 66245-350 is a 50-position rectangular receptacle connector with IDC (Insulation Displacement Contact) termination and gold plating. This connector is designed for ribbon cable applications with wire gauges of 28-30 AWG. The product is currently obsolete, making identification of equivalent and substitute parts essential for system maintenance, repair, and legacy equipment support.

Substitute Part Grouping Explanation

Substitute parts for the 66245-350 are qualified based on the following critical parameters that determine functional compatibility:

Connector Type & Position Count: Both substitutes maintain 50-position receptacle configuration
Pitch & Row Configuration: 0.100" (2.54mm) pitch with 2-row layout preserved across all parts
Cable Termination Method: IDC termination maintained for ribbon cable compatibility
Wire Gauge Compatibility: Substitutes support overlapping or equivalent wire gauge ranges (26-30 AWG encompasses the original 28-30 AWG specification)
Contact Finish: Gold plating maintained across all parts
Mounting Configuration: Free hanging in-line mounting preserved

The two substitute parts (TE Connectivity 5-215882-0 and 3M 89150-0101) meet these core electrical and mechanical requirements, enabling direct functional replacement in ribbon cable interconnect applications.

Engineering Selection Recommendations

TE Connectivity 5-215882-0 is the manufacturer-recommended substitute. This part is active in production with RoHS compliance and supports an extended wire gauge range (26-30 AWG solid; 28 AWG stranded), providing broader compatibility with ribbon cable specifications. The contact finish thickness of 31.5µin exceeds the original specification, offering enhanced durability.

3M 89150-0101 is an alternative substitute with active product status and ROHS3 compliance. This part supports 26-28 AWG wire gauge, which overlaps with the original 28-30 AWG range. Contact finish thickness matches the original specification at 30.0µin.

Both substitutes provide active product status and current compliance certifications, addressing the obsolescence of the original 66245-350 part. Selection between the two should be based on wire gauge requirements of the specific ribbon cable application and compliance requirements of the end system.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5-215882-0 and 3M 89150-0101 be used interchangeably with the 66245-350?

A: Both parts meet the core electrical and mechanical requirements for substitution: 50-position receptacle configuration, 0.100" pitch, 2-row layout, IDC termination, and gold contact finish. Wire gauge compatibility exists within the specified ranges. Physical form factor and mounting characteristics are equivalent.

Q: What is the difference between "Closed End" and "Feed Through" features?

A: The original 66245-350 features a closed end design, while both substitutes feature feed-through design. This difference affects the internal contact arrangement but does not impact functional compatibility for standard ribbon cable interconnect applications.

Q: Are there wire gauge limitations when substituting?

A: The original part specifies 28-30 AWG. The TE Connectivity substitute supports 26-30 AWG (solid) and 28 AWG (stranded), providing full compatibility. The 3M substitute supports 26-28 AWG, which overlaps the original specification. Verify that the ribbon cable gauge matches the selected substitute's supported range.

Q: What compliance considerations apply to these substitutes?

A: The original 66245-350 is RoHS non-compliant. Both substitutes are RoHS compliant (TE Connectivity is RoHS compliant; 3M is ROHS3 compliant). If the end application requires RoHS compliance, either substitute is acceptable. The original part should not be used in new RoHS-regulated applications.

Q: Does the color difference between parts affect compatibility?

A: Color is a visual identifier only and does not affect electrical or mechanical compatibility. The original part is blue; both substitutes are gray. This difference is cosmetic and does not impact connector function or performance.
