66900-930 Equivalent & Substitute Parts

Part Overview

The 66900-930 is a 30-position rectangular receptacle connector manufactured by Amphenol ICC (FCI) in the Quickie™ series. This connector is designed for IDC (Insulation Displacement Contact) termination with ribbon cable in the 28-30 AWG range. The part is classified as obsolete, making identification of compatible substitute components essential for ongoing system support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 66900-930 is based on the following critical parameters that must remain consistent:

• Connector Type & Position Count: Both main and substitute parts must be 30-position receptacles to maintain mechanical and electrical compatibility with existing mating connectors.
• Pitch & Row Configuration: The 0.100" (2.54mm) pitch and 2-row spacing are fundamental to physical fit and must not vary.
• Cable Termination Method: IDC termination is required for ribbon cable compatibility.
• Contact Finish: Gold plating ensures electrical performance and corrosion resistance.
• Mounting Configuration: Free hanging in-line mounting must be preserved for system integration.

The substitute part 1658620-7 (TE Connectivity AMP-Latch series) meets these core requirements. The wire gauge specification differs (26-28 AWG vs. 28-30 AWG), which represents a compatible overlap range suitable for substitution in IDC applications.

Parameter Comparison

Engineering Selection Recommendations

The 1658620-7 serves as a functional substitute for the obsolete 66900-930 based on matching mechanical and electrical specifications. Key considerations for selection:

Product Status: The 66900-930 is obsolete with limited inventory (815 pcs). The 1658620-7 is active production with substantial availability (8723 pcs), ensuring long-term procurement viability.

Compliance: The 1658620-7 is RoHS compliant, whereas the 66900-930 is non-compliant. Systems requiring RoHS certification should transition to the substitute part.

Wire Gauge Compatibility: The substitute accepts 26-28 AWG ribbon cable, which overlaps with the original specification of 28-30 AWG at 28 AWG. This overlap ensures compatibility with standard ribbon cable gauges used in IDC applications.

Contact Geometry: The substitute uses forked contacts instead of female sockets. Both contact types are standard for IDC receptacles and function with corresponding IDC plug contacts.

Frequently Asked Questions (FAQ)

Q: Can the 1658620-7 directly replace the 66900-930 in existing assemblies?

A: Yes, provided the mating connector is a standard 30-position IDC plug with 0.100" (2.54mm) pitch. The mechanical footprint and electrical interface are compatible.

Q: What is the significance of the wire gauge difference (28-30 AWG vs. 26-28 AWG)?

A: Both specifications accommodate 28 AWG ribbon cable, which is the standard gauge for 30-position IDC applications. The substitute's 26-28 AWG range allows use of slightly heavier gauge cable if required by system design.

Q: Does the contact type difference (Female Socket vs. Forked) affect compatibility?

A: No. Both contact types are designed for IDC termination and function with standard IDC plug contacts. The contact geometry difference does not impact electrical performance or mechanical fit.

Q: Why is RoHS compliance important for this substitution?

A: RoHS compliance is mandatory for products sold into regulated markets and industries. The substitute's RoHS compliance ensures the part meets environmental and safety standards required by many OEMs and end-use applications.

Q: Is the substitute available in the same packaging as the original?

A: The substitute is supplied in tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What is the inventory status for procurement planning?

A: The 66900-930 has 815 pcs in stock (obsolete status). The 1658620-7 has 8723 pcs available (active production), providing reliable supply for new designs and ongoing support.
