66900-044 Equivalent & Substitute Parts

Part Overview

The 66900-044 is a 44-position rectangular receptacle connector manufactured by Amphenol ICC (FCI) in the Quickie™ series. This connector features IDC (Insulation Displacement Contact) termination for ribbon cable applications with 28-30 AWG wire gauge capability. The part is currently classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations where this connector type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 66900-044 is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Position count (44 positions)
• Pitch and row spacing (0.100" / 2.54mm)
• Cable termination method (IDC)
• Contact finish (Gold)
• Mounting configuration (Free Hanging In-Line)

Two substitute parts meet these criteria. The 66900-044LF is a direct manufacturer equivalent from Amphenol ICC with identical electrical and mechanical specifications but differs in product status (Active vs. Obsolete) and RoHS compliance. The 9444-6044 from 3M is a cross-manufacturer substitute that maintains all critical parameters but operates with a narrower wire gauge range (26-28 AWG versus 28-30 AWG).

Parameter Comparison

Engineering Selection Recommendations

The 66900-044LF is the primary substitute for the obsolete 66900-044. Both parts are manufactured by Amphenol ICC and share identical electrical and mechanical specifications. The 66900-044LF maintains active product status and achieves RoHS compliance, making it suitable for new designs and systems requiring regulatory adherence.

The 9444-6044 from 3M is a secondary cross-manufacturer option. While it maintains all critical connector parameters, the wire gauge specification differs (26-28 AWG versus 28-30 AWG). This part is RoHS compliant and actively produced. Selection of the 9444-6044 requires verification that the narrower wire gauge range accommodates the intended ribbon cable specification.

Frequently Asked Questions (FAQ)

Q: Can the 66900-044LF be used as a direct replacement for the 66900-044?

A: Yes. The 66900-044LF is electrically and mechanically equivalent to the 66900-044. Both parts feature identical position count, pitch, row spacing, IDC termination, wire gauge range, and contact finish specifications. The primary differences are product status (Active versus Obsolete) and RoHS compliance.

Q: What is the key difference between the 66900-044 and the 9444-6044?

A: The primary difference is wire gauge specification. The 66900-044 accommodates 28-30 AWG ribbon cable, while the 9444-6044 is rated for 26-28 AWG. All other electrical and mechanical parameters, including position count, pitch, row spacing, and IDC termination, are identical. Compatibility depends on the actual ribbon cable gauge used in the application.

Q: Are there packaging differences between these parts?

A: Yes. The 66900-044 is supplied without specified packaging, the 66900-044LF is packaged in tubes, and the 9444-6044 is supplied in bulk packaging. Packaging selection may affect procurement logistics and handling requirements but does not impact electrical or mechanical compatibility.

Q: Do all three parts meet RoHS requirements?

A: No. The 66900-044 is RoHS non-compliant. Both the 66900-044LF and 9444-6044 are RoHS compliant. For applications requiring regulatory compliance, either the 66900-044LF or 9444-6044 must be selected.

Q: Can the 9444-6044 be used in applications originally designed for the 66900-044?

A: The 9444-6044 is mechanically and electrically compatible provided the ribbon cable wire gauge falls within the 26-28 AWG range. If the original design specifies 28-30 AWG cable, the 9444-6044 may not accommodate the full gauge range. Verification of cable specifications is required before substitution.
