Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 746288-9 are identified based on strict electrical and mechanical parameter compatibility. The following parameters determine substitution eligibility:

Critical Matching Parameters:

• Connector Type: Receptacle
• Number of Positions: 40
• 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
• Mounting Type: Free Hanging (In-Line)
• Contact Finish Thickness: 30.0µin (0.76µm)
• Features: Feed Through, Polarizing Key
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts meeting all critical parameters are listed below. Variations in contact type (forked versus female socket), contact finish material composition (gold versus gold-palladium), color, packaging, and product status are noted but do not preclude functional substitution when electrical and mechanical specifications align.

Engineering Selection Recommendations

TE Connectivity AMP Connectors 1658622-9 (Direct Substitute)

The 1658622-9 is the primary equivalent for the obsolete 746288-9. Both connectors share identical mechanical and electrical specifications within the AMP-Latch series. The 1658622-9 is currently in active production status with significantly higher inventory availability (3100 pieces). This part achieves ROHS3 compliance, addressing regulatory requirements that the original 746288-9 does not meet. Contact finish composition permits either gold or gold-palladium plating while maintaining the specified 30.0µin thickness. Packaging is supplied in tube format. This part is the recommended primary selection for new designs and ongoing production requiring direct compatibility with the 746288-9 specification.

3M 89140-0101 (Similar Substitute)

The 89140-0101 provides functional equivalence with all critical electrical and mechanical parameters matching the 746288-9 specification. This part operates within the 891 series and is actively produced by 3M with the highest inventory availability (11058 pieces). The contact type differs (female socket versus forked), and the connector color is gray rather than black. Both the 1658622-9 and 89140-0101 achieve ROHS3 compliance. The 89140-0101 carries REACH Unaffected status, providing additional regulatory clarity. Packaging is supplied in bulk format. This part is suitable for applications where cross-manufacturer compatibility and maximum supply availability are prioritized.

Frequently Asked Questions (FAQ)

Q: Can the 1658622-9 directly replace the 746288-9 in existing designs?

A: Yes. The 1658622-9 maintains identical pitch (0.100"), row configuration (2 rows with 0.100" spacing), position count (40), IDC termination method, wire gauge range (26-28 AWG), and contact finish thickness (30.0µin). Both connectors feature feed-through and polarizing key functionality. The primary difference is product status: the 1658622-9 is active production while the 746288-9 is obsolete.

Q: What is the difference between the contact types in the 746288-9 and 89140-0101?

A: The 746288-9 uses forked contacts, while the 89140-0101 uses female socket contacts. Both contact types are designed for IDC ribbon cable termination at 26-28 AWG and maintain the same electrical performance characteristics and contact finish thickness specification. The contact type difference does not affect mating compatibility with standard 0.100" pitch male connectors.

Q: Are there compliance differences between the substitute parts?

A: Yes. The original 746288-9 is RoHS non-compliant. Both substitute parts (1658622-9 and 89140-0101) achieve ROHS3 compliance. The 89140-0101 additionally carries REACH Unaffected status, while the 1658622-9 lists REACH status as Vendor Undefined. All three parts share identical ECCN (EAR99) and HTSUS (8536.69.4051) classifications.

Q: Does the gold-palladium contact finish option on the 1658622-9 affect compatibility?

A: No. The 1658622-9 specification permits either gold or gold-palladium plating at the same 30.0µin thickness. Both finishes maintain electrical performance and mating characteristics equivalent to the 746288-9 gold finish specification.

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

A: The 1658622-9 is supplied in tube packaging. The 89140-0101 is supplied in bulk packaging. The original 746288-9 packaging format is not specified in the available data. Packaging selection should be based on production workflow and inventory management requirements.

Q: Are the substitute parts suitable for ribbon cable applications?

A: Yes. Both substitute parts are specified for ribbon cable termination using the IDC method at 26-28 AWG wire gauge, identical to the 746288-9 specification. The feed-through feature and polarizing key are retained in both substitutes.

Q: What is the moisture sensitivity level for all three connectors?

A: All three connectors (746288-9, 1658622-9, and 89140-0101) carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or use.
