Amphenol ICC 66900-010 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 66900-010 is a 10-position rectangular receptacle connector with IDC termination for 28-30 AWG ribbon cable. This connector is classified as obsolete product status. Equivalent and substitute parts are necessary to maintain design compatibility in applications where the original part is no longer available or where active product alternatives offer improved compliance and availability.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (10), pitch (0.100"/2.54mm), number of rows (2), row spacing (0.100"/2.54mm), cable termination method (IDC), wire type (ribbon cable), contact finish (gold), and mounting type (free hanging in-line).

Wire gauge compatibility extends to 26-28 AWG substitutes, as this range encompasses the original 28-30 AWG specification and maintains electrical and mechanical compatibility with IDC termination. Substitute parts meeting these core parameters are functionally equivalent regardless of manufacturer, series designation, or packaging format.

Engineering Selection Recommendations

Primary Substitute (Same Manufacturer): The 66900-010LF is the direct active equivalent from Amphenol ICC (FCI). It maintains identical electrical and mechanical specifications while offering RoHS compliance and active product status. This part is recommended for designs requiring minimal qualification changes.

HARTING SEK Series Substitutes: Parts 09185105813, 09185106813, and 09185107804 are functionally equivalent with 26-28 AWG wire gauge compatibility. All are ROHS3 compliant with active product status. The 09185106813 offers the highest inventory availability (2875 pcs) and includes feed-through and strain relief features matching the original design intent.

TE Connectivity AMP-Latch Series Substitutes: Parts 1-215911-0, 1-215915-0, and 1-215919-0 provide equivalent 10-position IDC receptacle functionality with ROHS3 compliance and active status. Wire gauge specification is not provided for these parts; compatibility must be confirmed through TE Connectivity technical documentation.

3M Series Substitutes: Parts 3473-6010 and 89110-0003 are ROHS3 compliant alternatives with 26-28 AWG compatibility. The 89110-0003 includes feed-through and strain relief features aligned with the original connector design.

All substitute parts listed maintain the critical parameters of 10-position configuration, 0.100" pitch, 2-row layout, IDC termination, and gold contact finish. Selection should prioritize active product status and compliance certifications appropriate to the application environment.

Frequently Asked Questions (FAQ)

Q: Can I use a 26-28 AWG rated connector as a substitute for the 28-30 AWG original part?

A: Yes. The 26-28 AWG specification encompasses the upper range of the original 28-30 AWG requirement. IDC termination technology accommodates this overlap, and all substitute parts listed with 26-28 AWG rating are electrically and mechanically compatible with ribbon cable in this gauge range.

Q: What is the difference between feed-through and closed-end connector configurations?

A: Feed-through connectors allow ribbon cable to pass through the connector body, enabling daisy-chain or multi-point connections. Closed-end connectors terminate the cable at the connection point. Selection depends on the application circuit topology. The original 66900-010 includes feed-through capability; equivalent substitutes with this feature are 66900-010LF, 09185105813, 09185106813, 09185107804, 1-215911-0, 1-215915-0, 1-215919-0, and 89110-0003.

Q: Does packaging format affect electrical or mechanical performance?

A: No. Packaging format (tube, tray, bulk, cut tape) is a supply chain and handling consideration only. All parts with identical electrical and mechanical specifications perform identically in the application regardless of packaging.

Q: Why do some substitute parts include a polarizing key feature not present in the original?

A: Polarizing keys are design enhancements that prevent incorrect connector mating orientation. This feature improves assembly reliability without affecting electrical performance. Connectors with polarizing keys are backward compatible with non-polarized mating components.

Q: What does RoHS compliance mean for connector selection?

A: RoHS (Restriction of Hazardous Substances) compliance indicates the connector meets environmental and safety standards for lead-free manufacturing. The original 66900-010 is RoHS non-compliant; all active substitutes listed are RoHS3 compliant, meeting current regulatory requirements for new designs and manufacturing.

Q: Are TE Connectivity AMP-Latch connectors compatible with the original Amphenol ICC design?

A: Yes. The AMP-Latch series maintains the same 10-position, 0.100" pitch, 2-row configuration with IDC termination and gold contact finish. Mechanical and electrical compatibility is established through these core parameters. Wire gauge compatibility should be confirmed through application-specific requirements.
