Engineering Selection Recommendations

TE Connectivity AMP Connectors 1658623-9 (Direct Substitute)

The 1658623-9 is the primary direct substitute for the obsolete 746290-9. Both connectors are manufactured by TE Connectivity within the AMP-Latch series and share identical mechanical and electrical specifications. The 1658623-9 is classified as Active product status, ensuring ongoing availability and supply chain support. This part achieves ROHS3 compliance, addressing regulatory requirements that the original 746290-9 does not meet. The contact finish specification permits gold or gold-palladium composition while maintaining the required 30.0µin (0.76µm) thickness. The 1658623-9 is supplied in bulk packaging and maintains unlimited moisture sensitivity rating.

3M 89140-0001 (Similar Substitute)

The 89140-0001 provides an alternative substitute from 3M within the 891 series. This connector meets all critical electrical and mechanical parameters, including the 40-position, 0.100" pitch, 2-row configuration with IDC termination for 26-28 AWG ribbon cable. The 89140-0001 is Active product status with ROHS3 compliance and REACH Unaffected certification. The primary distinction is the contact type (female socket versus forked) and housing color (gray versus black). This part is available in high inventory quantities and maintains the same contact finish thickness specification.

Both substitute parts are suitable for applications requiring the 746290-9 specification. Selection between them depends on specific design requirements regarding contact type compatibility, housing color matching, and manufacturer preference. Both substitutes provide improved regulatory compliance compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the 1658623-9 directly replace the 746290-9 in existing designs?

A: Yes. The 1658623-9 meets all critical parameters: 40 positions, 0.100" pitch, 2-row configuration, IDC termination, 26-28 AWG ribbon cable compatibility, and identical contact finish thickness. Both are AMP-Latch series receptacles with feed-through capability and free-hanging in-line mounting. The primary advantage is that 1658623-9 is Active product status with ROHS3 compliance.

Q: What is the difference between the contact types in these substitutes?

A: The 746290-9 and 1658623-9 both feature forked contact type. The 89140-0001 uses female socket contact type. Both contact types are designed for IDC termination with ribbon cable and maintain the same 30.0µin (0.76µm) contact finish thickness. Contact type selection depends on mating connector design and application requirements.

Q: Are there color differences between these connectors?

A: Yes. The 746290-9 and 1658623-9 are black. The 89140-0001 is gray. Color differences do not affect electrical or mechanical function but may impact visual identification and assembly aesthetics.

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

A: The 746290-9 is RoHS non-compliant. Both 1658623-9 and 89140-0001 are ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the compliant substitutes are necessary. RoHS compliance addresses restrictions on hazardous substances in electrical and electronic equipment.

Q: How do the contact finish specifications compare?

A: All three connectors specify 30.0µin (0.76µm) contact finish thickness. The 746290-9 and 89140-0001 specify gold finish. The 1658623-9 permits gold or gold-palladium composition. This flexibility in the 1658623-9 does not affect electrical performance or compatibility, as both finishes meet the thickness requirement.

Q: What packaging considerations apply to these substitutes?

A: The 746290-9 packaging is listed as undefined. The 1658623-9 is supplied in bulk packaging. The 89140-0001 is supplied in bulk packaging. Bulk packaging is standard for high-volume applications and does not affect connector function or compatibility.

Q: Are there REACH or export control differences?

A: The 746290-9 has Vendor Undefined REACH status. The 1658623-9 also has Vendor Undefined REACH status. The 89140-0001 has REACH Unaffected status, indicating no restrictions under REACH regulations. All three connectors are classified as EAR99 for export control purposes. For applications requiring REACH compliance documentation, the 89140-0001 provides explicit unaffected status.

Q: Can these connectors be used interchangeably in the same application?

A: Yes, within the constraints of contact type compatibility. The 1658623-9 is the most direct replacement due to identical series designation and forked contact type. The 89140-0001 is compatible if the mating connector design accommodates female socket contacts. Both substitutes maintain the same electrical and mechanical specifications for IDC ribbon cable termination, pitch, row spacing, and mounting configuration.
