TE Connectivity AMP Connectors 746285-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 746285-3 is a 16 Position Rectangular Receptacle Connector designed for IDC (Insulation Displacement Contact) termination with ribbon cable. This connector features gold-plated forked contacts rated for 26-28 AWG wire gauge and incorporates a polarizing key for proper mating orientation. The 746285-3 is classified as obsolete, necessitating identification of active equivalent and substitute parts to maintain design continuity and ensure ongoing component availability for production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 746285-3 is determined by strict equivalence across the following critical parameters: connector type (receptacle), number of positions (16), pitch (0.100"/2.54mm), number of rows (2), row spacing (0.100"/2.54mm), cable termination method (IDC), wire gauge compatibility (26-28 AWG), contact finish (gold), contact finish thickness (15.0µin/0.38µm), and presence of feed-through and polarizing key features. All identified substitute parts meet these electrical and mechanical requirements. Variations in manufacturer identity, series designation, contact type nomenclature (forked versus female socket), housing color, packaging format, and product status are permitted within the substitution framework provided the core functional parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1658621-3 serves as the direct equivalent replacement for the obsolete 746285-3. Both parts are manufactured by TE Connectivity within the AMP-Latch series and share identical electrical and mechanical specifications. The 1658621-3 carries active product status and ROHS3 compliance, providing regulatory advantage for new designs and ongoing production. This part is available in higher inventory quantities (2335 pieces) compared to the obsolete 746285-3 (707 pieces).

The 3M 89116-0101HA represents an alternative cross-manufacturer substitute. This part maintains all critical functional parameters including connector type, position count, pitch, row configuration, IDC termination, wire gauge, contact finish, and polarizing key features. The 89116-0101HA differs in manufacturer identity, series designation (891 versus AMP-Latch), contact type nomenclature (female socket versus forked), and housing color (gray versus black). The 89116-0101HA is active and ROHS3 compliant with the highest available inventory (3584 pieces).

For applications requiring RoHS3 compliance and active product status, both 1658621-3 and 89116-0101HA are suitable. For applications with existing TE Connectivity ecosystem integration, the 1658621-3 is preferred. For applications requiring maximum component availability, the 89116-0101HA offers the largest stock position.

Frequently Asked Questions (FAQ)

Q: Can the 1658621-3 directly replace the obsolete 746285-3 in existing designs?

A: Yes. The 1658621-3 is electrically and mechanically equivalent to the 746285-3. Both parts feature identical connector type, position count, pitch, row spacing, IDC termination, wire gauge rating, contact finish, and polarizing key configuration. The 1658621-3 is the direct TE Connectivity equivalent.

Q: What are the differences between the TE Connectivity 1658621-3 and the 3M 89116-0101HA?

A: The primary differences are manufacturer (TE Connectivity versus 3M), series designation (AMP-Latch versus 891), contact type nomenclature (forked versus female socket), and housing color (black versus gray). All critical electrical and mechanical parameters are identical. Both parts are active and ROHS3 compliant.

Q: Are there packaging differences between these substitute parts?

A: Yes. The 746285-3 packaging is not specified. The 1658621-3 is supplied in tube packaging. The 89116-0101HA is supplied in bulk packaging. Packaging format selection depends on production workflow and inventory management requirements.

Q: Can the 89116-0101HA be used in applications originally designed for the 746285-3?

A: Yes. The 89116-0101HA meets all electrical and mechanical requirements for substitution. The cross-manufacturer design ensures functional compatibility. Verify connector mating interface compatibility with existing plug connectors in your specific application.

Q: What is the significance of the RoHS compliance difference?

A: The 746285-3 is RoHS non-compliant. Both substitute parts (1658621-3 and 89116-0101HA) are ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the substitute parts provide regulatory compliance. For legacy applications without RoHS requirements, all three parts are functionally equivalent.

Q: Are the contact finish specifications identical across all three parts?

A: Yes. All three parts feature gold contact finish with 15.0µin (0.38µm) thickness, ensuring equivalent electrical performance and corrosion resistance.

Q: Which substitute part should be selected for new production designs?

A: For new designs, either the 1658621-3 or 89116-0101HA is appropriate. The 1658621-3 maintains TE Connectivity ecosystem continuity. The 89116-0101HA offers higher inventory availability. Both are active products with ROHS3 compliance. Selection depends on supply chain strategy and existing connector ecosystem preferences.
