Primary Compatibility Criteria:

Connector type: Receptacle
Number of positions: 10
Pitch: 0.100" (2.54mm)
Number of rows: 2
Row spacing: 0.100" (2.54mm)
Cable termination method: IDC
Wire type: Ribbon Cable
Contact finish: Gold
Mounting type: Free Hanging (In-Line)
Features: Feed Through, Polarizing Key

Secondary Compatibility Considerations:

Wire gauge compatibility: 26-28 AWG (primary) or 28-30 AWG (acceptable with verification of application requirements)
Contact type: Forked or Female Socket
Contact finish thickness: 15.0µin minimum
Product status: Active status preferred for long-term availability

Substitute parts are grouped into two categories:

Category 1 - Direct Equivalent (Identical Specifications): Parts that match all primary compatibility criteria with identical wire gauge and contact specifications.

Category 2 - Functional Equivalent (Compatible with Parameter Variance): Parts that match all primary compatibility criteria but differ in wire gauge range (28-30 AWG vs. 26-28 AWG), contact type (Female Socket vs. Forked), or contact finish thickness. These parts maintain mechanical and electrical compatibility within the specified connector family.

Engineering Selection Recommendations

Primary Recommendation: TE Connectivity AMP Connectors 1658621-1

The 1658621-1 is the optimal substitute for the obsolete 746285-1. This part maintains identical specifications across all critical parameters: 10-position receptacle configuration, 0.100" pitch, 2-row layout, IDC termination for 26-28 AWG ribbon cable, forked contact type, and gold contact finish at 15.0µin thickness. The 1658621-1 is classified as active product status, ensuring long-term availability and supply chain continuity. The part carries ROHS3 compliance, meeting current regulatory requirements. Packaging is provided in tube format.

Secondary Recommendation: 3M 89110-0101HA

The 89110-0101HA provides functional equivalence with identical electrical and mechanical specifications to the 746285-1. This part matches the 10-position receptacle configuration, 0.100" pitch, 2-row layout, IDC termination for 26-28 AWG ribbon cable, and gold contact finish at 15.0µin thickness. The contact type is female socket rather than forked, but maintains compatibility within the rectangular connector family. The 89110-0101HA is active product status with ROHS3 compliance. Inventory availability is substantial at 9496 pieces. Packaging is provided in bulk format.

Tertiary Recommendations: Amphenol ICC (FCI) Quickie™ Series

The Amphenol ICC (FCI) parts 66900-210LF, 66901-210, 66902-010LF, and 66902-210LF provide functional equivalence with the following considerations:

All four parts maintain the 10-position receptacle configuration, 0.100" pitch, 2-row layout, and IDC termination for ribbon cable.
Wire gauge specification is 28-30 AWG, which overlaps with the 746285-1 specification of 26-28 AWG. Application requirements must confirm compatibility with the narrower gauge range.
Contact type is female socket across all four parts.
All parts include feed-through and polarizing key features.
Parts 66900-210LF, 66902-010LF, and 66902-210LF include strain relief features.
Contact finish thickness ranges from 30.0µin to 50.0µin, exceeding the 746285-1 specification of 15.0µin.
Product status is active for all four parts, ensuring availability.
RoHS compliance status varies: 66900-210LF and 66902-210LF are RoHS Compliant; 66901-210 is RoHS non-compliant.

Frequently Asked Questions (FAQ)

Q: Can the 1658621-1 be used as a direct replacement for the 746285-1?

A: Yes. The 1658621-1 maintains identical specifications across all critical parameters: connector type, number of positions, pitch, row configuration, cable termination method, wire gauge, contact finish, and features. The primary difference is product status: the 1658621-1 is active while the 746285-1 is obsolete. The 1658621-1 is packaged in tube format.

Q: What is the difference between the forked contact type in the 746285-1 and the female socket contact type in the 89110-0101HA?

A: Both contact types are designed for IDC termination to ribbon cable and maintain electrical and mechanical compatibility within the rectangular connector family. The forked contact and female socket contact differ in internal geometry but serve the same functional purpose of accepting and retaining the mating connector pin. Selection between these contact types depends on the specific mating connector design in the application.

Q: Why do the Amphenol ICC (FCI) Quickie™ series parts specify 28-30 AWG wire gauge instead of 26-28 AWG?

A: The Quickie™ series parts are designed for 28-30 AWG ribbon cable. The 746285-1 is specified for 26-28 AWG. The 28-30 AWG range overlaps with the 26-28 AWG range at 28 AWG. Application compatibility depends on the actual wire gauge used in the cable assembly. If the application uses 26 AWG or 27 AWG ribbon cable, the Quickie™ series parts may not provide optimal contact retention. Confirmation of cable gauge is required before substitution.

Q: What is the significance of the contact finish thickness difference between the 746285-1 (15.0µin) and the Amphenol ICC (FCI) parts (30.0µin to 50.0µin)?

A: Contact finish thickness affects contact durability and wear resistance. The 746285-1 specifies 15.0µin gold plating. The Amphenol ICC (FCI) parts provide thicker gold plating at 30.0µin to 50.0µin, which offers enhanced durability and extended contact life. Thicker plating does not compromise compatibility but provides improved performance characteristics.

Q: Are there RoHS compliance considerations when substituting the 746285-1?

A: The 746285-1 is RoHS non-compliant. The recommended substitute 1658621-1 is ROHS3 compliant, meeting current regulatory requirements. The 89110-0101HA is also ROHS3 compliant. If RoHS compliance is a design requirement, the 1658621-1 or 89110-0101HA are appropriate selections. The Amphenol ICC (FCI) parts have mixed RoHS status: 66900-210LF and 66902-210LF are RoHS Compliant; 66901-210 is RoHS non-compliant.

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

A: The 1658621-1 is packaged in tube format. The 89110-0101HA is packaged in bulk format. The Amphenol ICC (FCI) parts are packaged as follows: 66900-210LF in tube, 66901-210 in bulk, 66902-010LF in tube, and 66902-210LF in tube. Packaging selection depends on production volume and inventory management requirements.

Q: Can the 746285-1 be used interchangeably with parts from different manufacturers?

A: Yes, within the constraints of the specified parameters. The 746285-1 is mechanically and electrically compatible with substitute parts that maintain identical pitch, row configuration, number of positions, cable termination method, and mounting type. Manufacturer differences do not affect compatibility provided that the critical parameters are matched. The TE Connectivity 1658621-1 and 3M 89110-0101HA are direct equivalents. The Amphenol ICC (FCI) Quickie™ series parts are functional equivalents with the wire gauge and contact type considerations noted above.

Q: Is the polarizing key feature present on all substitute parts?

A: The polarizing key feature is present on the 1658621-1, 89110-0101HA, 66900-210LF, 66901-210, and 66902-210LF. The 66902-010LF does not include the polarizing key feature. If polarizing key functionality is required for the application, the 66902-010LF is not suitable as a substitute.
