Amphenol ICC 66245-320 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 66245-320 is a 20-position rectangular receptacle connector with IDC (Insulation Displacement Contact) termination for ribbon cable applications. This connector features gold-plated contacts rated for 28-30 AWG wire gauges and is part of the Quickie™ series. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 66245-320 is determined by the following critical parameters:

• Connector Configuration: 20-position receptacle with 0.100" (2.54mm) pitch and 2-row arrangement
• Termination Method: IDC (Insulation Displacement Contact) for ribbon cable
• Contact System: Female socket with gold plating at 30.0µin thickness
• Wire Gauge Compatibility: Acceptable range includes 26-30 AWG for IDC termination
• Mechanical Interface: Free hanging (in-line) mounting with polarizing key feature
• Environmental Rating: MSL 1 (Unlimited moisture sensitivity level)

The 3M 89120-0101 qualifies as a substitute based on matching connector type, position count, pitch, row configuration, termination method, contact finish specification, and environmental ratings. The wire gauge specification of 26-28 AWG on the substitute part overlaps with the original 28-30 AWG range, providing functional compatibility for ribbon cable applications within the overlapping 28 AWG specification.

Parameter Comparison

Engineering Selection Recommendations

The 3M 89120-0101 serves as the manufacturer-recommended substitute for the obsolete Amphenol ICC 66245-320. Selection of this substitute is supported by:

• Functional Equivalence: Identical connector configuration, pitch, row arrangement, and IDC termination method ensure mechanical and electrical compatibility
• Contact Specification Match: Gold plating at 30.0µin thickness and female socket contact type provide equivalent electrical performance
• Wire Gauge Overlap: The 26-28 AWG specification of the substitute encompasses the 28 AWG midpoint of the original 28-30 AWG range, supporting ribbon cable applications within this common gauge
• Active Product Status: The 3M part is currently in active production with substantial inventory availability (42,511 pcs), ensuring long-term sourcing reliability
• Improved Compliance: The substitute achieves ROHS3 compliance, addressing regulatory requirements that may apply to new system designs or component replacements

Frequently Asked Questions (FAQ)

Q: Can the 3M 89120-0101 directly replace the Amphenol ICC 66245-320 in existing applications?

A: Yes, for applications using 28 AWG ribbon cable. The substitute matches all critical mechanical and electrical parameters including connector type, position count, pitch, row configuration, IDC termination, contact finish, and environmental rating. Wire gauge compatibility exists at the 28 AWG specification, which falls within both the original 28-30 AWG and substitute 26-28 AWG ranges.

Q: What is the difference between the "Closed End" feature on the original part and the "Feed Through" feature on the substitute?

A: These features describe different connector end configurations. The closed end on the original part seals one end of the connector body, while the feed through on the substitute allows passage through the connector. Both configurations maintain the same electrical and mechanical interface for IDC ribbon cable termination and are compatible for direct substitution.

Q: Does the wire gauge difference affect compatibility?

A: The wire gauge specifications overlap at 28 AWG. Applications using 28 AWG ribbon cable are fully compatible with both parts. Applications using 29-30 AWG ribbon cable should verify that the substitute's 26-28 AWG specification meets the specific application requirements, as the upper gauge limit differs.

Q: What is the significance of the RoHS compliance difference?

A: The original Amphenol ICC part is RoHS non-compliant, while the 3M substitute is ROHS3 compliant. For new designs or systems subject to RoHS regulations, the 3M substitute provides compliance. For legacy system maintenance where RoHS compliance is not required, both parts remain functionally equivalent.

Q: Are there any packaging differences between these parts?

A: The original part is listed with unspecified packaging, while the substitute is supplied in bulk packaging. Verify bulk packaging specifications meet your procurement and handling requirements.
