Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 746285-9 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector type: Receptacle
• Number of positions: 40
• Pitch: 0.100" (2.54mm)
• Row configuration: 2 rows with 0.100" (2.54mm) spacing
• Cable termination method: IDC
• Mounting configuration: Free Hanging (In-Line)
• Contact finish: Gold
• Features: Feed Through and Polarizing Key

Secondary Compatibility Criteria:

• Wire gauge compatibility: 26-28 AWG (primary specification) or 28-30 AWG (acceptable range overlap)
• Contact finish thickness: 15.0µin (0.38µm) or greater
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts must satisfy all primary criteria and maintain compatibility within secondary criteria ranges. The three identified substitutes meet these requirements with variations noted in contact type, wire gauge range, and product status.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred):

The TE Connectivity AMP Connectors 1658621-9 is the primary substitute for the obsolete 746285-9. Both connectors are from the same manufacturer and AMP-Latch series, with identical electrical and mechanical specifications including 40 positions, 0.100" pitch, 2-row configuration, IDC termination, and 26-28 AWG wire gauge compatibility. The 1658621-9 is classified as Active with ROHS3 compliance, providing superior long-term availability and regulatory alignment compared to the obsolete, non-compliant original part.

Alternative Substitutes:

The 3M 89140-0101HA (Series 891) provides full compatibility with identical wire gauge (26-28 AWG), contact finish thickness (15.0µin), and all mechanical parameters. This connector is Active and ROHS3 compliant, offering an alternative source from a different manufacturer with established supply availability.

The Amphenol ICC (FCI) 66900-240LF (Quickie™ series) is compatible with all mechanical and electrical parameters. This connector operates within an overlapping wire gauge range (28-30 AWG) and features enhanced contact finish thickness (30.0µin) and integrated strain relief. The 66900-240LF is Active and RoHS compliant, suitable for applications where the wire gauge range and additional strain relief feature are acceptable.

Compliance Considerations:

All three substitute parts are Active products with current RoHS compliance status (ROHS3 or RoHS Compliant), addressing the non-compliant status of the obsolete 746285-9. Selection should prioritize compliance requirements for new designs and production environments subject to regulatory mandates.

Frequently Asked Questions (FAQ)

Q: Can the 1658621-9 be used as a direct replacement for the 746285-9?

A: Yes. The 1658621-9 is a direct equivalent with identical specifications across all critical parameters: 40 positions, 0.100" pitch, 2-row configuration, IDC termination, 26-28 AWG wire gauge, gold contact finish, and feed-through with polarizing key features. Both are from TE Connectivity AMP-Latch series. The primary difference is product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What is the difference between the contact types (Forked vs. Female Socket)?

A: The 746285-9 and 1658621-9 feature forked contacts, while the 66900-240LF and 89140-0101HA feature female socket contacts. Both contact types are designed for IDC ribbon cable termination and provide equivalent electrical performance within their respective connector designs. Contact type selection depends on mating connector specifications and system design requirements.

Q: Are there wire gauge compatibility issues between substitutes?

A: The 746285-9, 1658621-9, and 89140-0101HA all specify 26-28 AWG wire gauge. The 66900-240LF specifies 28-30 AWG, which overlaps the upper range of the original specification. The 28-30 AWG range is compatible with 28 AWG ribbon cables used in the original design. Applications using 26-27 AWG ribbon cables should prioritize the 1658621-9 or 89140-0101HA for exact wire gauge matching.

Q: What packaging options are available?

A: The 1658621-9 is supplied in Tube packaging. The 66900-240LF is supplied in Tube packaging. The 89140-0101HA is supplied in Bulk packaging. Packaging selection affects inventory management, handling, and cost considerations for production environments.

Q: Which substitute offers the best long-term availability?

A: The 1658621-9 offers the highest inventory level (11708 Pcs) and is classified as Active with ROHS3 compliance, providing optimal long-term availability and regulatory support. The 89140-0101HA (2269 Pcs) and 66900-240LF (1146 Pcs) also provide Active status with established supply chains.

Q: Are all substitutes RoHS compliant?

A: The 1658621-9 and 89140-0101HA are ROHS3 compliant. The 66900-240LF is RoHS compliant. The original 746285-9 is RoHS non-compliant. For applications subject to RoHS regulations, all three substitutes meet compliance requirements.

Q: What is the significance of contact finish thickness differences?

A: The 746285-9, 1658621-9, and 89140-0101HA specify 15.0µin (0.38µm) contact finish thickness. The 66900-240LF specifies 30.0µin (0.76µm) with GXT™ enhanced finish. The thicker finish on the 66900-240LF provides additional corrosion resistance and contact durability, beneficial for harsh environmental applications.

Q: Can substitutes be intermixed in the same system?

A: All substitutes are mechanically and electrically compatible with each other due to identical pitch, row spacing, position count, and IDC termination. However, connector color coding differs (Black, Blue, Gray), which may affect visual identification in production and field service environments. Standardizing on a single substitute part number is recommended for system consistency.
