TE Connectivity AMP Connectors 746290-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 746290-1 is a 10 Position Rectangular Receptacle Connector designed for IDC (Insulation Displacement Contact) termination with ribbon cable in the 26-28 AWG wire gauge range. This connector features gold contact finish, feed-through capability, and operates in the AMP-Latch series with a 0.100" (2.54mm) pitch configuration across 2 rows.

The 746290-1 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production and field service requirements for applications utilizing this connector specification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 746290-1 are identified based on strict electrical and mechanical parameter compatibility. The following parameters establish substitution eligibility:

Critical Matching Parameters:

• Connector Type: Receptacle
• Number of Positions: 10
• Pitch: 0.100" (2.54mm)
• Number of Rows: 2
• Row Spacing: 0.100" (2.54mm)
• Cable Termination: IDC
• Wire Gauge: 26-28 AWG
• Wire Type: Ribbon Cable
• Contact Finish Thickness: 30.0µin (0.76µm)
• Mounting Type: Free Hanging (In-Line)
• Features: Feed Through
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these critical parameters. Variations in contact finish material (Gold versus Gold-Palladium), connector color, and product status are noted but do not preclude functional substitution within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

1658623-1 (Direct Substitute - TE Connectivity AMP Connectors)

The 1658623-1 is the primary direct substitute for the obsolete 746290-1. Both parts are manufactured by TE Connectivity AMP Connectors within the AMP-Latch series. The 1658623-1 maintains identical electrical and mechanical specifications including pitch, row configuration, IDC termination, wire gauge compatibility, and contact finish thickness. The 1658623-1 is classified as Active product status, ensuring ongoing availability and supply chain support. The 1658623-1 achieves ROHS3 compliance, addressing regulatory requirements that the original 746290-1 does not meet. Contact finish is specified as Gold or Gold-Palladium, both acceptable within the 30.0µin (0.76µm) thickness specification. Packaging is provided in Tube format with 1140 units in current inventory.

89110-0001 (Similar Substitute - 3M)

The 89110-0001 is a cross-manufacturer substitute manufactured by 3M within the 891 series. This connector meets all critical electrical and mechanical parameters: 10 positions, 0.100" pitch, 2-row configuration, IDC termination, 26-28 AWG wire gauge, and identical contact finish thickness. The 89110-0001 is classified as Active product status with ROHS3 compliance. The primary distinction is manufacturer origin (3M versus TE Connectivity) and connector color (Gray versus Black). Contact type is specified as Female Socket rather than Forked, representing a design variation within the same functional category. Packaging is provided in Bulk format with 7632 units in current inventory.

Both substitute parts satisfy the critical parameters for functional substitution. Selection between 1658623-1 and 89110-0001 depends on design requirements regarding manufacturer preference, color specification, and packaging format.

Frequently Asked Questions (FAQ)

Q: Can the 1658623-1 directly replace the obsolete 746290-1 in existing designs?

A: Yes. The 1658623-1 maintains identical pitch (0.100"), row configuration (2 rows with 0.100" spacing), position count (10), IDC termination method, wire gauge range (26-28 AWG), and contact finish thickness (30.0µin). Mechanical and electrical compatibility is established through these matching parameters.

Q: What is the difference between the contact finish specifications "Gold" and "Gold or Gold-Palladium" on the 1658623-1?

A: The 1658623-1 contact finish is specified as Gold or Gold-Palladium, both meeting the 30.0µin (0.76µm) thickness requirement. This specification flexibility does not affect substitution eligibility, as both finish options satisfy the electrical and mechanical requirements established for the 746290-1.

Q: Why is the 89110-0001 listed as a "Similar" substitute rather than a "Direct" substitute?

A: The 89110-0001 is manufactured by 3M rather than TE Connectivity and is designated within the 891 series rather than the AMP-Latch series. While all critical electrical and mechanical parameters match, the cross-manufacturer origin and series designation classify it as a similar substitute. The contact type specification (Female Socket versus Forked) also represents a design variation, though both types function within the IDC termination framework.

Q: Does the color difference between the 746290-1 (Black) and 89110-0001 (Gray) affect compatibility?

A: Color is a cosmetic parameter that does not affect electrical or mechanical compatibility. Selection based on color depends on design aesthetics or application-specific requirements, not functional substitution criteria.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the 1658623-1 and 89110-0001 are ROHS3 compliant. The original 746290-1 is RoHS non-compliant. Substitution with either part addresses regulatory compliance requirements for new designs or updated production runs.

Q: What packaging formats are available for the substitute parts?

A: The 1658623-1 is packaged in Tube format (1140 units in inventory). The 89110-0001 is packaged in Bulk format (7632 units in inventory). Packaging selection depends on procurement volume and handling requirements.

Q: Can the 1658623-1 and 89110-0001 be used interchangeably in the same application?

A: Both parts meet the critical electrical and mechanical parameters for the 746290-1 specification. Interchangeability depends on design requirements regarding manufacturer preference, series compatibility, contact type specification, and color. Verification of mating connector compatibility with the specific contact type (Forked versus Female Socket) is necessary for final design confirmation.

Q: What is the Moisture Sensitivity Level (MSL) for the substitute parts?

A: Both substitute parts maintain MSL 1 (Unlimited), identical to the original 746290-1. This classification indicates no moisture sensitivity restrictions for storage, handling, or deployment.
