Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 89947-328LF is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle) and contact type (Female Socket)
• Position count (28 positions) and pitch geometry (0.079" / 2.00mm)
• Row configuration (2 rows with 0.079" / 2.00mm spacing)
• Cable termination method (IDC for ribbon cable)
• Wire gauge compatibility (28 AWG)
• Contact finish specification (Gold at 30.0µin / 0.76µm thickness)
• Mechanical features (Feed Through, Polarizing Key)
• Series compatibility (Minitek® 2.00mm)

The 89947-728LF meets all substitution criteria as a direct equivalent, with the primary distinction being its active product status and enhanced fastening mechanism (Friction Lock).

Parameter Comparison

Engineering Selection Recommendations

The 89947-728LF is the manufacturer-recommended substitute for the obsolete 89947-328LF. Both connectors maintain identical electrical and mechanical specifications across all critical parameters including position count, pitch, row configuration, contact finish, and IDC termination capability.

The 89947-728LF offers the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, the 89947-728LF carries RoHS compliance certification, meeting current regulatory requirements for electronic component procurement in many jurisdictions.

The addition of Friction Lock fastening on the 89947-728LF provides enhanced mechanical retention compared to the main part, improving connector stability in applications subject to vibration or repeated mating cycles.

Frequently Asked Questions (FAQ)

Q: Can the 89947-728LF be used as a direct replacement for the 89947-328LF?

A: Yes. Both connectors share identical specifications for position count (28), pitch (0.079" / 2.00mm), row configuration, contact type (Female Socket), contact finish (Gold), and IDC termination for 28 AWG ribbon cable. The connectors are mechanically and electrically interchangeable.

Q: What is the difference between the 89947-328LF and 89947-728LF?

A: The primary differences are product status and fastening mechanism. The 89947-328LF is obsolete with unspecified fastening, while the 89947-728LF is an active product with Friction Lock fastening. The 89947-728LF also carries RoHS compliance certification.

Q: Why is the 89947-328LF classified as obsolete?

A: The 89947-328LF has reached end-of-life status in the manufacturer's product portfolio. The 89947-728LF represents the current active equivalent within the Minitek® 2.00mm series.

Q: Are there packaging differences between these connectors?

A: The 89947-328LF packaging is not specified in available documentation. The 89947-728LF is supplied in Tube packaging.

Q: Does the Friction Lock fastening on the 89947-728LF affect compatibility?

A: No. The Friction Lock mechanism provides additional mechanical retention without affecting electrical performance or mating compatibility with standard Minitek® 2.00mm plug connectors.

Q: What is the moisture sensitivity level for these connectors?

A: Both connectors carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
