• Mounting Type: Free Hanging (In-Line)
• Features: Feed Through, Polarizing Key
• Contact Finish Thickness: 30.0µin (0.76µm)
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Contact Type: Forked or Female Socket designs are functionally equivalent for IDC ribbon cable termination
• Contact Finish: Gold or Gold-Palladium finishes meet the same electrical and environmental performance requirements
• Connector Color: Black or Gray housing does not affect electrical or mechanical compatibility
• Packaging Format: Tube or Bulk packaging does not affect component functionality

The substitute parts listed below satisfy all mandatory matching parameters and fall within allowable variations.

Engineering Selection Recommendations

TE Connectivity AMP Connectors 1658622-1

The 1658622-1 is the primary direct substitute for the obsolete 746288-1. Both connectors are manufactured by TE Connectivity within the AMP-Latch series and maintain identical mechanical and electrical specifications. The 1658622-1 is classified as an active product with ROHS3 compliance, providing improved regulatory alignment compared to the non-compliant 746288-1. The contact finish specification permits Gold or Gold-Palladium, both of which meet the 30.0µin thickness requirement. This part is available in Tube packaging and offers the highest inventory availability at 3680 pieces.

3M 89110-0101

The 89110-0101 is a functionally equivalent substitute from 3M within the 891 series. This connector maintains all critical mechanical and electrical parameters including pitch, row spacing, IDC termination, wire gauge, and contact finish thickness. The contact type differs as Female Socket rather than Forked; however, both designs are compatible with standard IDC ribbon cable termination. The 89110-0101 is classified as an active product with ROHS3 compliance and REACH Unaffected status. Housing color is Gray rather than Black. This part is available in Bulk packaging with 3986 pieces in inventory.

Regulatory Compliance Consideration

Both substitute parts provide ROHS3 compliance, addressing the non-compliant status of the obsolete 746288-1. Selection between the two substitutes should account for design requirements regarding connector series compatibility, contact type preference, and packaging format needs.

Frequently Asked Questions (FAQ)

Q: Can the 1658622-1 directly replace the 746288-1 in existing designs?

A: Yes. The 1658622-1 maintains identical pitch (0.100"), row spacing (0.100"), number of positions (10), mounting type (Free Hanging In-Line), IDC termination method, wire gauge (26-28 AWG), and contact finish thickness (30.0µin). Both connectors feature feed-through and polarizing key functionality. The primary difference is product status: 1658622-1 is active and ROHS3 compliant, while 746288-1 is obsolete and non-compliant.

Q: What is the difference between the forked contact type in 746288-1 and the female socket contact type in 89110-0101?

A: Both contact types are designed for IDC ribbon cable termination and provide equivalent electrical performance. The forked design and female socket design differ in physical geometry but function identically when mated with standard IDC plug connectors. Selection between these contact types depends on existing mating connector specifications in the system design.

Q: Are the Gold and Gold-Palladium contact finishes in the 1658622-1 interchangeable?

A: Yes. Both finishes meet the specified contact finish thickness of 30.0µin (0.76µm) and provide equivalent electrical and environmental performance. The 1658622-1 specification permits either finish; actual finish type is determined by manufacturing lot and availability.

Q: Does the housing color difference between Black (746288-1, 1658622-1) and Gray (89110-0101) affect compatibility?

A: No. Housing color is a cosmetic attribute and does not affect electrical, mechanical, or functional compatibility. Color selection may be driven by design documentation or visual identification requirements only.

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

A: The 1658622-1 is available in Tube packaging. The 89110-0101 is available in Bulk packaging. The 746288-1 original part does not specify packaging format. Packaging selection should align with procurement and inventory management requirements.

Q: Are both substitute parts suitable for new designs requiring ROHS3 compliance?

A: Yes. Both the 1658622-1 and 89110-0101 are ROHS3 compliant. The original 746288-1 is non-compliant and should not be used in new designs subject to ROHS3 requirements.

Q: What is the moisture sensitivity level for these connectors?

A: All three connectors (746288-1, 1658622-1, and 89110-0101) have a Moisture Sensitivity Level of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or use.

Q: Can I use the 89110-0101 in applications where the original design specified the AMP-Latch series?

A: The 89110-0101 belongs to the 3M 891 series rather than the TE Connectivity AMP-Latch series. While the connectors are mechanically and electrically equivalent, design documentation and mating connector specifications should be reviewed to confirm compatibility with existing AMP-Latch series components in the system.
