Amphenol ICC 66245-240LF Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 66245-240LF is a 40-position rectangular receptacle connector with IDC (Insulation Displacement Contact) termination, designed for ribbon cable applications with 28-30 AWG wire gauge. This connector features gold-plated contacts, a polarizing key, and closed-end design for secure mating. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and component sourcing.

Substitute Part Grouping Explanation

The 3M CHG-2040-J01010-KCP qualifies as a direct substitute for the Amphenol ICC 66245-240LF based on the following critical parameters:

• Connector Configuration: Both are 40-position rectangular receptacles with 2-row arrangement and 0.100" (2.54mm) pitch
• Termination Method: Both use IDC technology for ribbon cable attachment
• Contact System: Both feature female socket contacts with gold plating at 30.0µin (0.76µm) thickness
• Mechanical Features: Both include closed-end design and polarizing key for proper orientation
• Wire Gauge Compatibility: The substitute accepts 26-28 AWG wire, which overlaps with the original 28-30 AWG specification at the 28 AWG common point
• Environmental Rating: Both have MSL 1 (Unlimited) moisture sensitivity classification

Parameter Comparison

Engineering Selection Recommendations

The 3M CHG-2040-J01010-KCP is the designated manufacturer-recommended substitute for the obsolete Amphenol ICC 66245-240LF. Selection of this substitute is supported by:

• Active Product Status: The 3M part is currently in active production with confirmed inventory availability, ensuring long-term sourcing capability
• Regulatory Compliance: The 3M substitute carries RoHS Compliance and REACH Unaffected certifications, meeting modern environmental and regulatory requirements
• Electrical and Mechanical Equivalence: Identical connector configuration, pitch, row arrangement, and contact specifications ensure direct functional compatibility
• Contact Metallurgy: Matching gold plating thickness (30.0µin) maintains equivalent electrical performance and contact reliability
• Wire Gauge Overlap: The 28 AWG common specification point between the original (28-30 AWG) and substitute (26-28 AWG) provides direct compatibility for standard ribbon cable applications

Frequently Asked Questions (FAQ)

Q: Can the 3M CHG-2040-J01010-KCP directly replace the Amphenol ICC 66245-240LF in existing assemblies?

A: Yes. Both connectors share identical 40-position, 2-row configuration with 0.100" pitch, IDC termination, and gold contact specifications. The connectors are mechanically and electrically interchangeable for ribbon cable applications using 28 AWG wire.

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

A: The 28 AWG specification is common to both parts, providing direct compatibility. The 3M substitute accepts a broader range (26-28 AWG) compared to the original (28-30 AWG). For applications using 28 AWG ribbon cable, both connectors perform identically.

Q: Are there any mechanical differences between these connectors?

A: Both connectors feature identical mechanical specifications: closed-end design, polarizing key, free-hanging in-line mounting, and 2-row arrangement. The only cosmetic difference is connector color (blue vs. gray), which does not affect functionality.

Q: Why is the Amphenol ICC part obsolete?

A: Product obsolescence is determined by the manufacturer and typically reflects end-of-life decisions. The 3M CHG-2040-J01010-KCP provides functional continuity for applications requiring 40-position IDC rectangular receptacles.

Q: Does the substitute meet current regulatory requirements?

A: Yes. The 3M CHG-2040-J01010-KCP is RoHS Compliant and REACH Unaffected, meeting current environmental and regulatory standards. The original Amphenol ICC part does not specify these certifications.

Q: Can the 3M substitute accommodate both ribbon cable and discrete wire?

A: Yes. The 3M CHG-2040-J01010-KCP supports both ribbon cable and discrete wire termination via IDC, providing greater application flexibility than the original part, which specifies ribbon cable only.
