Parameter Comparison

Engineering Selection Recommendations

1658623-2 (Direct Substitute - TE Connectivity AMP Connectors)

The 1658623-2 is the primary direct substitute for the obsolete 746290-2. Both connectors are manufactured by TE Connectivity AMP Connectors within the AMP-Latch series and share identical mechanical and electrical specifications. The 1658623-2 is currently in active production status with 9228 units in stock, providing superior supply chain availability compared to the obsolete 746290-2.

The 1658623-2 offers ROHS3 compliance, representing an advancement in regulatory compliance over the RoHS non-compliant 746290-2. Contact finish options include Gold or Gold-Palladium, both meeting the 30.0µin (0.76µm) thickness specification. This substitute is suitable for direct replacement in applications where the 746290-2 was originally specified.

89114-0001 (Similar Substitute - 3M)

The 89114-0001 is a functionally equivalent substitute manufactured by 3M within the 891 series. This connector maintains all critical electrical and mechanical parameters including 14 positions, 0.100" pitch, 2-row configuration, IDC termination, and 26-28 AWG ribbon cable compatibility.

The primary distinction is the contact type: the 89114-0001 employs Female Socket contacts compared to the Forked contacts in the 746290-2. Both contact types are standard for IDC rectangular connectors and provide equivalent electrical performance within this connector category. The 89114-0001 features gold contact finish and is ROHS3 compliant with 6529 units in stock.

The 89114-0001 housing color is gray rather than black, representing a cosmetic difference without functional impact. This substitute is appropriate for applications where cross-manufacturer compatibility is acceptable and where the Female Socket contact type is compatible with the mating connector design.

Frequently Asked Questions (FAQ)

Q: Can the 1658623-2 be used as a direct replacement for the 746290-2?

A: Yes. The 1658623-2 is a direct substitute manufactured by the same company (TE Connectivity AMP Connectors) within the same series (AMP-Latch). All critical parameters including position count, pitch, row configuration, IDC termination, wire gauge, and contact finish thickness are identical. The 1658623-2 is currently in active production, making it the preferred replacement for the obsolete 746290-2.

Q: What is the difference between the Forked contact type in the 746290-2 and the Female Socket contact type in the 89114-0001?

A: Both contact types are standard for IDC rectangular connectors and provide equivalent electrical performance. The Forked contact design and Female Socket design differ in physical geometry but both accommodate the same ribbon cable termination method and wire gauge range (26-28 AWG). Selection between these contact types depends on compatibility with the mating connector design in your application.

Q: Does the Gold-Palladium contact finish option in the 1658623-2 affect compatibility with the original 746290-2 specification?

A: No. The 1658623-2 offers both Gold and Gold-Palladium contact finish options, both meeting the 30.0µin (0.76µm) thickness specification. Either finish option maintains electrical and mechanical compatibility with applications originally designed for the 746290-2 gold contact finish.

Q: Is the gray color of the 89114-0001 a functional difference from the black 746290-2?

A: No. Housing color is a cosmetic attribute without functional impact on electrical performance or mechanical compatibility. The gray color of the 89114-0001 does not affect its suitability as a substitute in applications where the 746290-2 was originally specified.

Q: What is the significance of the RoHS3 compliance in the substitute parts?

A: The 1658623-2 and 89114-0001 are both ROHS3 compliant, representing compliance with current regulatory requirements for restricted substances. The original 746290-2 is RoHS non-compliant. For applications subject to RoHS regulations, the substitute parts provide regulatory compliance. For applications without RoHS requirements, both compliant and non-compliant parts are functionally equivalent.

Q: Are there inventory considerations when selecting between the two substitute parts?

A: Yes. The 1658623-2 has 9228 units in stock, while the 89114-0001 has 6529 units in stock. Both represent substantial inventory availability. The 1658623-2, being from the same manufacturer as the original part, may be preferred for supply chain consistency. The 89114-0001 provides an alternative source from a different manufacturer (3M).

Q: Can both substitute parts be used interchangeably in the same application?

A: Both substitute parts meet all critical electrical and mechanical parameters for the 746290-2. However, interchangeability depends on mating connector compatibility. The contact type difference (Forked vs. Female Socket) and housing color difference (Black vs. Gray) must be evaluated against your specific mating connector design and application requirements.
