3M 3334-6660 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The 3M 3334-6660 is a 60-position rectangular receptacle connector designed for IDC (Insulation Displacement Contact) termination with ribbon cable. This connector operates in the 3000 series and is actively manufactured. The part features gold-plated contacts, polarizing key, and strain relief for secure in-line applications. Substitute parts may be required due to inventory availability, lead time constraints, or specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 3334-6660 is determined by strict alignment of the following critical parameters:

• Connector Type & Position Count: Must be receptacle with exactly 60 positions
• Pitch & Row Configuration: Must maintain 0.100" (2.54mm) pitch with 2 rows at 0.100" (2.54mm) spacing
• Cable Termination Method: Must support IDC termination for ribbon cable
• Wire Gauge Compatibility: Must accept 26-28 AWG ribbon cable
• Contact Finish: Must feature gold plating for electrical performance
• Mounting Configuration: Must be free hanging in-line design

The TE Connectivity AMP Connectors part 1-1658621-1 meets all these critical parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the 3M 3334-6660 and TE Connectivity 1-1658621-1 are active products with current manufacturing status. The 3M part carries ROHS3 compliance, while the TE Connectivity substitute is RoHS compliant. Both parts share identical ECCN and HTSUS classifications, indicating equivalent regulatory treatment. The TE Connectivity part features forked contacts compared to the female socket design of the 3M part, and includes reduced strain relief features. Selection between these parts should be based on application-specific contact type requirements and feature set compatibility.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-1658621-1 directly replace the 3M 3334-6660 in all applications?

A: Both parts maintain identical pitch, row spacing, position count, wire gauge compatibility, and IDC termination method. The primary difference is contact type (forked vs. female socket) and strain relief features. Compatibility depends on whether the mating connector and application design accommodate the forked contact configuration.

Q: What is the significance of the 0.100" (2.54mm) pitch specification?

A: Pitch defines the center-to-center distance between adjacent contacts. Both parts maintain 0.100" pitch, ensuring mechanical and electrical compatibility with standard ribbon cable connectors designed for this spacing.

Q: Are there packaging differences between these parts?

A: The 3M 3334-6660 is supplied in bulk packaging, while the TE Connectivity 1-1658621-1 is supplied in tube packaging. Packaging does not affect electrical or mechanical performance.

Q: What does IDC termination mean?

A: IDC (Insulation Displacement Contact) termination allows ribbon cable to be inserted directly into the connector without stripping insulation. The connector's contacts pierce the cable insulation to establish electrical connection.

Q: Do both parts support the same wire gauge range?

A: Yes, both parts accept 26-28 AWG ribbon cable, ensuring compatibility with standard ribbon cable specifications.
