Amphenol ICC 66900-640 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 66900-640 is a 40-position rectangular receptacle connector with IDC (Insulation Displacement Contact) termination for 28-30 AWG ribbon cable. This connector belongs to the Quickie™ series and features gold-plated contacts with strain relief in a dual-row configuration at 0.100" pitch. The part is currently obsolete, making equivalent substitutes necessary for ongoing applications and maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 66900-640 is determined by the following critical parameters that must remain constant:

• Connector configuration: 40-position receptacle with 2 rows at 0.100" pitch and 0.100" row spacing
• Termination method: IDC for ribbon cable
• Contact type: Female socket with gold finish
• Mounting style: Free hanging in-line configuration
• Cable compatibility: Support for ribbon cable in the 26-30 AWG range

The substitute parts listed below maintain these core electrical and mechanical parameters. Wire gauge tolerance variations (26-28 AWG versus 28-30 AWG) fall within acceptable substitution criteria for IDC ribbon cable connectors, as both ranges accommodate standard ribbon cable specifications used in this connector class.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes: HARTING 09185406813 and 09185407813 are functionally equivalent to the 66900-640. Both parts are active products with ROHS3 compliance and identical mechanical and electrical specifications. The difference between these two HARTING options is packaging: 09185406813 is supplied in trays, while 09185407813 is supplied in bulk. Selection between these two depends on inventory management and procurement requirements.

Secondary Substitute: TE Connectivity 4-215911-0 provides functional equivalence with the addition of right-angle mounting capability alongside the standard in-line configuration. This part is also ROHS3 compliant and active. The wire gauge specification is not provided for this part, but it maintains all other critical parameters for substitution.

Compliance Consideration: The original 66900-640 is RoHS non-compliant. All three substitute parts are ROHS3 compliant, making them suitable for applications requiring modern regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the HARTING SEK series connectors directly replace the Amphenol ICC Quickie™ 66900-640?

A: Yes. Both HARTING parts (09185406813 and 09185407813) maintain identical pitch, row configuration, position count, and IDC termination method. The mechanical and electrical interfaces are compatible for direct substitution in applications using 40-position ribbon cable connectors.

Q: What is the difference between wire gauge specifications (28-30 AWG versus 26-28 AWG)?

A: The 66900-640 specifies 28-30 AWG, while the HARTING substitutes specify 26-28 AWG. Both ranges fall within standard ribbon cable specifications for this connector class. The overlap at 28 AWG ensures compatibility. Wire gauge selection should be based on the actual ribbon cable gauge used in the application.

Q: Are there packaging differences between the HARTING substitute options?

A: Yes. HARTING 09185406813 is packaged in trays, while 09185407813 is packaged in bulk. Both parts are electrically and mechanically identical. Packaging selection depends on procurement volume and inventory handling requirements.

Q: Does the TE Connectivity 4-215911-0 offer any additional functionality?

A: The TE Connectivity part supports both free hanging in-line and right-angle mounting configurations, providing additional mounting flexibility compared to the original 66900-640, which supports only in-line mounting. All other electrical and mechanical parameters remain equivalent.

Q: What compliance certifications apply to these substitute parts?

A: All three substitute parts are ROHS3 compliant and carry MSL rating 1 (unlimited moisture sensitivity level). The original 66900-640 is RoHS non-compliant. For applications requiring RoHS compliance, the substitute parts are the appropriate selection.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes, provided the application uses ribbon cable within the compatible gauge range (26-30 AWG). The identical pitch, row spacing, position count, and IDC termination method ensure mechanical and electrical compatibility. Verify that the actual ribbon cable gauge in your application falls within the specified range for your selected substitute part.
