Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 89947-744LF is determined by strict equivalence across the following critical parameters:

• Connector Series & Pitch: Must be Minitek® 2.00mm series with 0.079" (2.00mm) pitch to ensure mechanical and electrical compatibility with mating connectors and PCB layouts
• Position Count & Configuration: Must maintain 44 positions in a 2-row configuration with identical row spacing (0.079")
• Connector Orientation: Must be a receptacle with female socket contacts for compatibility with plug-type mating connectors
• Cable Termination Method: Must support IDC termination for ribbon cable compatibility
• Wire Gauge Compatibility: Must accommodate 28 AWG ribbon cable
• Contact Material & Finish: Must feature gold-plated contacts with equivalent finish thickness (30.0µin / 0.76µm) for electrical performance and corrosion resistance
• Functional Features: Must include feed-through and polarizing key features for proper alignment and signal integrity

The substitute part 89947-344LF meets all these criteria and is classified as an active product, providing improved supply chain availability compared to the obsolete 89947-744LF.

Parameter Comparison

Engineering Selection Recommendations

The 89947-344LF is the direct substitute for the obsolete 89947-744LF. Both connectors are manufactured by Amphenol ICC and share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the 89947-744LF is obsolete, while the 89947-344LF is active and currently in production.

For new designs or ongoing production requiring this connector type, the 89947-344LF should be selected to ensure long-term supply chain continuity and manufacturer support. Both parts maintain equivalent REACH compliance and export classification (EAR99), with no regulatory barriers to substitution.

The 89947-344LF is supplied in tube packaging, whereas packaging information for the 89947-744LF was not specified. This packaging difference does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 89947-344LF be used as a direct replacement for the 89947-744LF in existing assemblies?

A: Yes. Both connectors are identical in electrical and mechanical specifications, including pitch, position count, contact type, termination method, and contact finish. They are mechanically and electrically interchangeable.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The 89947-744LF is obsolete and no longer manufactured. The 89947-344LF is an active product in current production. For applications requiring this connector type, the 89947-344LF ensures availability and ongoing manufacturer support.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and MSL rating (1 - Unlimited). No compliance barriers exist to substitution.

Q: Does the packaging difference (tube vs. unspecified) affect compatibility?

A: No. Packaging affects logistics and handling but does not impact electrical or mechanical performance. The connector itself is identical regardless of packaging format.

Q: What parameters must remain constant for a connector to be considered a substitute for the 89947-744LF?

A: The following parameters must be identical: series (Minitek® 2.00mm), pitch (0.079"), position count (44), row configuration (2 rows), connector type (receptacle), contact type (female socket), cable termination method (IDC), wire gauge (28 AWG), contact finish (gold, 30.0µin thickness), and functional features (feed-through, polarizing key).

Q: Can connectors from other manufacturers substitute for the Amphenol ICC 89947-744LF?

A: Substitution is limited to parts meeting all specified electrical and mechanical parameters. Only the 89947-344LF from Amphenol ICC is provided as an equivalent in this reference. Other manufacturers' parts would require independent verification of all parameters.
