Amphenol ICC 66245-326 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 66245-326 is a 26-position rectangular receptacle connector with IDC (Insulation Displacement Contact) termination for ribbon cable applications. This connector features gold-plated contacts rated for 28-30 AWG wire gauges and includes polarizing key features for secure mating. The product is classified as obsolete, necessitating identification of active equivalent components that maintain electrical and mechanical compatibility for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 66245-326 is determined by strict alignment with the following core parameters:

• 26-position configuration with 2-row layout at 0.100" (2.54mm) pitch
• Receptacle connector with female socket contacts
• IDC termination method for ribbon cable
• Gold contact finish at 30.0µin (0.76µm) thickness
• Free hanging in-line mounting configuration
• Polarizing key feature for keyed mating

The identified substitute parts maintain these critical parameters. Wire gauge compatibility is evaluated within the acceptable range of 26-30 AWG, as IDC contacts accommodate this spectrum. Both substitute parts are active products with current manufacturing status, addressing the obsolescence of the original component.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts satisfy the core electrical and mechanical requirements for direct replacement of the 66245-326. Selection between alternatives is based on compliance and product availability status:

TE Connectivity 2-215882-6 is an active product with ROHS3 compliance certification. This part maintains identical contact finish specifications and pitch geometry. The Mark II series provides current manufacturing support and supply chain continuity.

3M 89126-0101 is an active product with ROHS3 compliance and REACH unaffected status. Wire gauge specification of 26-28 AWG overlaps with the original 28-30 AWG range, accommodating standard ribbon cable applications. The 891 series offers high inventory availability.

Both parts feature feed-through contact design compared to the closed-end design of the original component. This configuration difference does not affect electrical performance in standard IDC ribbon cable termination applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2-215882-6 directly replace the Amphenol ICC 66245-326?

A: Yes. Both connectors share identical pitch (0.100"), position count (26), row configuration (2), contact type (female socket), termination method (IDC), and contact finish specifications (gold, 30.0µin). The Mark II series maintains mechanical and electrical compatibility for ribbon cable applications.

Q: What is the significance of the wire gauge difference between 28-30 AWG and 26-28 AWG?

A: IDC contacts are designed to accommodate a range of wire gauges. The 3M 89126-0101 specification of 26-28 AWG overlaps with the original 28-30 AWG range at 28 AWG, ensuring compatibility with standard ribbon cable gauges used in the original design.

Q: Why do the substitute parts have feed-through features while the original has a closed-end design?

A: Feed-through contact design is a manufacturing evolution that does not affect electrical performance in IDC ribbon cable termination. Both configurations provide equivalent signal integrity and contact reliability for this connector category.

Q: Are there compliance considerations when substituting the obsolete part?

A: The original 66245-326 is RoHS non-compliant. Both substitute parts are ROHS3 compliant, meeting current regulatory requirements for new designs and system updates. The 3M part additionally carries REACH unaffected status.

Q: What packaging options are available for these substitute parts?

A: The TE Connectivity 2-215882-6 is supplied in tray packaging, while the 3M 89126-0101 is supplied in bulk packaging. Packaging selection depends on procurement volume and handling requirements for your application.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, within the constraints of your system's mechanical envelope and color coding requirements. The original blue color of the 66245-326 differs from the gray color of both substitutes. Verify that color differentiation is not a functional requirement in your application.
