Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 746290-8 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Receptacle
• Number of Positions: 34
• 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)

The substitute parts listed below satisfy all mandatory matching parameters and are therefore electrically and mechanically compatible with the 746290-8 for direct replacement applications.

Engineering Selection Recommendations

TE Connectivity AMP Connectors 1658623-8 (Direct Substitute)

The 1658623-8 is the primary substitute for the obsolete 746290-8. Both connectors are manufactured by TE Connectivity within the AMP-Latch series and maintain identical electrical and mechanical specifications. The 1658623-8 is currently in active production status with higher inventory availability (1785 Pcs). The contact finish specification permits either gold or gold-palladium composition, both meeting the 30.0µin (0.76µm) thickness requirement. The 1658623-8 achieves ROHS3 compliance, addressing regulatory requirements that the original 746290-8 does not satisfy.

3M 89134-0001 (Similar Substitute)

The 89134-0001 provides functional equivalence across all critical electrical and mechanical parameters. This connector is manufactured by 3M within the 891 series and maintains active production status with substantial inventory availability (2845 Pcs). The contact type differs (female socket versus forked), and the connector housing color is gray rather than black. The 89134-0001 achieves both ROHS3 compliance and REACH unaffected status. Selection of this substitute is appropriate when cross-manufacturer compatibility is acceptable and supply chain considerations favor 3M sourcing.

Both substitute parts satisfy the mandatory parameter requirements for direct replacement in applications utilizing the 746290-8.

Frequently Asked Questions (FAQ)

Q: What makes the 1658623-8 and 89134-0001 suitable substitutes for the 746290-8?

A: Both substitute parts match all critical parameters: 34-position receptacle configuration, 0.100" (2.54mm) pitch, 2-row layout with 0.100" (2.54mm) row spacing, IDC termination for 26-28 AWG ribbon cable, 30.0µin (0.76µm) gold contact finish thickness, free-hanging in-line mounting, and feed-through capability. These parameters define mechanical and electrical compatibility for this connector category.

Q: Are there differences between the 1658623-8 and 89134-0001 that affect selection?

A: The 1658623-8 is manufactured by TE Connectivity (same manufacturer as the original 746290-8) and maintains identical series designation (AMP-Latch). The 89134-0001 is manufactured by 3M and uses a different series designation (891). The 89134-0001 features female socket contacts rather than forked contacts and has a gray housing instead of black. Both achieve ROHS3 compliance; the 89134-0001 additionally carries REACH unaffected status.

Q: Does the contact finish difference between gold and gold-palladium on the 1658623-8 affect compatibility?

A: The 1658623-8 specification permits either gold or gold-palladium contact finish, both meeting the 30.0µin (0.76µm) thickness requirement. This flexibility does not affect electrical or mechanical compatibility with the 746290-8 application.

Q: Why is the 746290-8 classified as obsolete?

A: The 746290-8 is no longer in active production. The 1658623-8 serves as the direct replacement within the TE Connectivity AMP-Latch product line, offering improved regulatory compliance (ROHS3) and continued manufacturing support.

Q: Can the 89134-0001 be used in applications originally designed for the 746290-8?

A: The 89134-0001 satisfies all mandatory electrical and mechanical parameters required for the 746290-8 application. However, the difference in contact type (female socket versus forked) and housing color (gray versus black) should be evaluated against specific application requirements and mating connector specifications.

Q: What is the significance of the MSL rating of 1 (Unlimited)?

A: An MSL rating of 1 indicates unlimited shelf life without moisture sensitivity concerns. All three connectors (746290-8, 1658623-8, and 89134-0001) share this rating, ensuring equivalent storage and handling requirements.

Q: Are there packaging differences between these connectors?

A: The 746290-8 packaging specification is not provided. The 1658623-8 and 89134-0001 are both supplied in bulk packaging. Specific packaging requirements should be confirmed with the supplier for procurement purposes.
