Amphenol ICC 66902-240 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 66902-240 is a 40-position rectangular receptacle connector designed for IDC (Insulation Displacement Contact) termination with ribbon cable. This connector features a dual-row configuration with 0.100" pitch spacing, gold-plated contacts, and integrated strain relief with polarizing key. The part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing system support and procurement planning.

Substitute Part Grouping Explanation

Substitution eligibility for the 66902-240 is determined by strict equivalence across the following critical parameters:

Connector Configuration: 40-position, dual-row receptacle with 0.100" pitch and 0.100" row spacing
Termination Method: IDC cable termination for ribbon cable compatibility
Contact Characteristics: Female socket contacts with gold plating
Mechanical Interface: Free hanging in-line mounting with polarizing key and strain relief
Electrical Performance: Support for 28-30 AWG wire gauge

Parts meeting all these criteria are classified as direct substitutes. Variations in packaging, RoHS compliance status, or contact finish thickness do not affect functional interchangeability within the specified electrical and mechanical parameters.

Engineering Selection Recommendations

66902-240LF is the primary substitute for the obsolete 66902-240. Both parts are manufactured by Amphenol ICC within the Quickie™ series and maintain identical electrical and mechanical specifications. The 66902-240LF carries active product status and RoHS compliance, making it the preferred choice for new designs and ongoing procurement. The primary distinction is packaging format (tube versus bulk) and regulatory compliance status.

CWR-217-40-0000 from CW Industries is a manufacturer-recommended alternative that meets all critical functional parameters. This part maintains the same 40-position, dual-row IDC receptacle configuration with identical pitch and row spacing. The CWR-217-40-0000 is actively produced and ROHS3 compliant. Contact finish thickness differs (10.0µin versus 30.0µin), but both specifications support the specified wire gauge and electrical performance requirements. Wire gauge specification is not provided for the CWR-217-40-0000; however, the connector's IDC termination design and physical dimensions are compatible with 28-30 AWG ribbon cable.

Frequently Asked Questions (FAQ)

Q: Can the 66902-240LF directly replace the obsolete 66902-240?

A: Yes. Both connectors share identical electrical and mechanical specifications within the Amphenol ICC Quickie™ series. The 66902-240LF is the direct successor with active product status and improved regulatory compliance.

Q: What is the difference between the Amphenol ICC and CW Industries options?

A: Both meet the core functional requirements for 40-position IDC receptacle connectors. The Amphenol ICC 66902-240LF maintains the original design lineage with GXT™ contact finish. The CW Industries CWR-217-40-0000 is a cross-manufacturer equivalent with standard gold plating. Selection depends on supply chain preference and existing connector inventory compatibility.

Q: Does contact finish thickness affect interchangeability?

A: Contact finish thickness does not affect functional interchangeability for IDC termination applications. Both 30.0µin and 10.0µin gold plating specifications support the specified wire gauge and electrical performance within the defined operating parameters.

Q: Are there packaging considerations for these substitutes?

A: The 66902-240LF is supplied in tube packaging, while the CWR-217-40-0000 is supplied in bulk packaging. Packaging format does not affect connector performance but may influence procurement logistics and handling procedures.

Q: What compliance certifications apply to each part?

A: The 66902-240 is RoHS non-compliant. The 66902-240LF is RoHS compliant. The CWR-217-40-0000 is ROHS3 compliant. All three parts are classified as EAR99 for export control purposes and share the same HTSUS tariff code.
