3M 4660-6201 Equivalent & Substitute Parts

Part Overview

The 3M 4660-6201 is a 60-position rectangular plug connector with IDC (Insulation Displacement Contact) termination, designed for discrete or ribbon cable applications with wire gauges of 26-28 AWG. This connector features gold-plated contacts, a 0.100" pitch configuration with 2-row layout, and latch lock/eject hook fastening. The part is actively manufactured and ROHS3 compliant, making it suitable for industrial and commercial applications requiring reliable signal and power distribution in compact form factors.

Equivalent parts are necessary when the primary manufacturer part becomes unavailable, when supply chain optimization is required, or when design flexibility allows for functionally compatible alternatives from different manufacturers while maintaining electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 4660-6201 is determined by strict equivalence across the following critical parameters:

• Connector Configuration: 60-position plug with 2-row layout at 0.100" pitch and 0.100" row spacing
• Termination Method: IDC cable termination for 26-28 AWG wire
• Contact System: Gold-plated male pins with 30.0µin finish thickness
• Mounting: Free hanging in-line configuration with latch lock/eject hook fastening
• Compliance: ROHS3 certification and EAR99 export classification

The TE Connectivity AMP Connectors part 2-111492-6 meets all these critical parameters and qualifies as a direct substitute. Variations in packaging format (bulk versus tray), connector color (gray versus black), and wire type support (discrete/ribbon versus ribbon only) do not affect functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 3M 4660-6201 and TE Connectivity 2-111492-6 are actively manufactured products with identical ROHS3 compliance and MSL ratings. Selection between these parts should be based on:

Availability and Lead Time: Current inventory shows 972 units of the 3M part and 909 units of the TE Connectivity part. Either part is suitable for immediate procurement.

Packaging Considerations: The 3M part is supplied in bulk packaging, while the TE Connectivity substitute is supplied in tray packaging. Tray packaging may provide advantages in automated assembly environments.

Wire Type Support: The 3M part explicitly supports both discrete and ribbon cable types, while the TE Connectivity part specifies ribbon cable. For applications using discrete wire exclusively, the 3M part provides documented compatibility.

Connector Features: The TE Connectivity part includes a polarizing key feature not listed for the 3M part, providing additional keying protection against incorrect mating.

Both parts carry identical export classification (EAR99) and tariff codes, ensuring equivalent regulatory treatment.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2-111492-6 directly replace the 3M 4660-6201 in existing designs?

A: Yes. Both connectors share identical electrical and mechanical specifications including 60-position configuration, 0.100" pitch, IDC termination for 26-28 AWG wire, and gold contact finish. Physical mating and electrical performance are equivalent.

Q: What is the difference between bulk and tray packaging?

A: Bulk packaging is loose component packaging suitable for manual assembly and small-volume applications. Tray packaging organizes components in structured trays optimized for automated pick-and-place assembly equipment. Functional performance is identical.

Q: Does the polarizing key on the TE Connectivity part affect compatibility?

A: The polarizing key is an additional feature that prevents incorrect mating orientation. It does not prevent mating with non-keyed connectors but provides enhanced protection against assembly errors. Existing cable assemblies designed for the 3M part will mate with the TE Connectivity part.

Q: Are both parts suitable for the same wire gauge range?

A: Yes. Both parts are rated for 26-28 AWG wire. The 3M part explicitly documents support for both stranded and solid wire types, while the TE Connectivity part specifies ribbon cable. For ribbon cable applications, both parts are fully compatible.

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

A: Both parts specify 30.0µin (0.76µm) gold plating thickness, ensuring equivalent contact resistance, durability, and corrosion resistance. This specification is critical for long-term reliability in signal and power distribution applications.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts carry identical ROHS3 compliance, MSL rating of 1 (unlimited), EAR99 export classification, and HTSUS tariff code 8536.69.4051. They are equivalent for all regulatory and compliance purposes.
