Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 746288-3 are identified based on electrical and mechanical parameter compatibility. The following parameters establish substitution eligibility:

Critical Matching Parameters:

• Connector Type: Receptacle
• Number of Positions: 16
• 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
• Features: Feed Through, Polarizing Key
• Mounting Type: Free Hanging (In-Line)
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts meeting all critical parameters are classified as direct equivalents capable of functional replacement in applications designed for the 746288-3. Variations in contact type, contact finish composition, color, and product status do not preclude substitution when all critical parameters align.

Engineering Selection Recommendations

TE Connectivity AMP Connectors 1658622-3

The 1658622-3 is a direct substitute for the obsolete 746288-3. Both connectors are manufactured by TE Connectivity within the AMP-Latch series and share identical electrical and mechanical specifications. The 1658622-3 is classified as an active product with current manufacturing support and availability. This part achieves RoHS Compliance, addressing regulatory requirements that the original 746288-3 does not meet. The contact finish specification permits Gold or Gold-Palladium composition, maintaining compatibility with existing mating plug connectors designed for the 746288-3. The 1658622-3 is the preferred substitute for new designs and ongoing production requiring regulatory compliance.

3M 89116-0101

The 89116-0101 is a similar substitute manufactured by 3M within the 891 series. This connector matches all critical electrical and mechanical parameters of the 746288-3, including 16-position configuration, 0.100" pitch, IDC termination, and 26-28 AWG ribbon cable compatibility. The 89116-0101 features a Female Socket contact type rather than the forked contact design of the original part, but maintains functional equivalence for IDC ribbon cable termination. This part is classified as active with ROHS3 Compliance and REACH Unaffected status. The 89116-0101 is suitable for applications where cross-manufacturer substitution is acceptable and where the Female Socket contact design is compatible with existing mating plug connectors.

Frequently Asked Questions (FAQ)

Q: Can the 1658622-3 directly replace the 746288-3 in existing applications?

A: Yes. The 1658622-3 matches all critical parameters of the 746288-3, including connector type, position count, pitch, row configuration, IDC termination method, wire gauge, and mounting type. Both connectors are designed to mate with identical plug connectors and accept 26-28 AWG ribbon cable. The 1658622-3 is the direct equivalent.

Q: What is the difference between the contact types in the 746288-3 and 89116-0101?

A: The 746288-3 uses a forked contact design, while the 89116-0101 uses a Female Socket contact design. Both contact types are compatible with standard IDC ribbon cable termination and are designed to mate with corresponding plug connectors. The contact type difference does not affect functional compatibility when mating with appropriate plug connectors.

Q: Are there compliance differences between the substitute parts and the original 746288-3?

A: Yes. The 746288-3 is RoHS non-compliant. The 1658622-3 is RoHS Compliant, and the 89116-0101 is ROHS3 Compliant. Both substitute parts meet current regulatory requirements. Applications subject to RoHS regulations should utilize the 1658622-3 or 89116-0101 rather than the original 746288-3.

Q: Does the Gold-Palladium contact finish option on the 1658622-3 affect compatibility?

A: No. The 1658622-3 contact finish specification permits either Gold or Gold-Palladium composition, both at 30.0µin (0.76µm) thickness. This specification maintains electrical and mechanical compatibility with mating plug connectors designed for the 746288-3, which specifies gold plating at the same thickness.

Q: What is the packaging difference between the 746288-3 and the substitute parts?

A: The 746288-3 packaging is not specified in available documentation. The 1658622-3 is supplied in Bulk packaging, and the 89116-0101 is supplied in Bulk packaging. Packaging format does not affect connector functionality or compatibility.

Q: Can the 89116-0101 be used in applications originally designed for the 746288-3?

A: Yes, provided that the mating plug connector is compatible with the Female Socket contact design of the 89116-0101. The 89116-0101 matches all critical electrical and mechanical parameters and is suitable for IDC ribbon cable termination in 16-position, 0.100" pitch configurations. Cross-manufacturer substitution is acceptable when contact design compatibility is confirmed.

Q: Why is the 746288-3 classified as obsolete?

A: The 746288-3 is no longer in active production. The 1658622-3 serves as the current production equivalent within the TE Connectivity AMP-Latch series. For new designs and ongoing production support, the 1658622-3 is the recommended part selection.

Q: Are all three connectors suitable for ribbon cable applications?

A: Yes. All three connectors are designed for IDC termination with ribbon cable in the 26-28 AWG wire gauge range. The IDC termination method allows direct connection to ribbon cable without individual wire stripping or crimping.
