Amphenol ICC 68645-023 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68645-023 is a rectangular connector header, right-angle configuration, with 50 positions at 2.54mm pitch. This through-hole, shrouded connector is designed for board-to-cable/wire applications with solder termination and detent lock fastening. The part is currently obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 68645-023 is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) - must match exactly
• Number of Positions: 50 - must match exactly
• Number of Rows: 2 - must match exactly
• Row Spacing - Mating: 0.100" (2.54mm) - must match exactly
• Mounting Type: Through Hole, Right Angle - must match exactly
• Shrouding: Shrouded - 4 Wall - must match exactly
• Termination: Solder - must match exactly
• Contact Shape: Square - must match exactly
• Material Flammability Rating: UL94 V-0 - must match exactly

All three substitute parts meet these core electrical and mechanical requirements. Variations in contact finish, insulation material, fastening type, and connector type (receptacle vs. header) are acceptable within the scope of functional equivalence for this product category.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are functionally equivalent to the 68645-023 based on core mechanical and electrical parameters. Selection should be based on the following criteria:

Molex 0741640050 and 0741640150 are both active products with ROHS3 compliance, offering improved regulatory status compared to the obsolete, RoHS non-compliant original part. Both employ Liquid Crystal Polymer insulation material and latch holder fastening. The primary difference between these two Molex options is contact finish: 0741640050 features gold mating contact finish, while 0741640150 uses tin. Selection between these two depends on application requirements for contact finish durability and corrosion resistance.

TE Connectivity 7-102570-2 is an active product with RoHS compliance and provides the closest connector type match to the original header configuration. This part specifies operating temperature range (-65°C ~ 105°C) and current rating (3A), offering defined performance parameters. The thermoplastic insulation material and detent lock fastening mechanism match the original design approach more closely than the Molex alternatives.

For new designs or long-term production, any of these three parts provide equivalent functionality. For direct replacement in existing assemblies, 7-102570-2 offers the most similar mechanical interface due to matching connector type and fastening mechanism.

Frequently Asked Questions (FAQ)

Q: Can the Molex receptacle connectors (0741640050, 0741640150) directly replace the Amphenol ICC header (68645-023)?

A: Yes. While the Molex parts are classified as receptacles and the original is a header, both connector types accommodate male pin contacts at identical pitch and position configurations. The functional mating interface remains compatible. Connector type designation reflects internal contact arrangement rather than external compatibility in this product category.

Q: What is the difference between Molex 0741640050 and 0741640150?

A: The primary difference is contact finish. The 0741640050 uses gold mating contact finish (15.0µin thickness), while the 0741640150 uses tin mating contact finish (150.0µin thickness). Both parts are otherwise identical in mechanical configuration, pitch, position count, and electrical characteristics. Gold finish typically provides superior corrosion resistance; tin finish offers cost advantages.

Q: Are all substitute parts RoHS compliant?

A: The original 68645-023 is RoHS non-compliant. Both Molex parts (0741640050, 0741640150) are ROHS3 compliant. The TE Connectivity 7-102570-2 is RoHS compliant. If RoHS compliance is required for your application, all three substitutes meet this requirement.

Q: What are the packaging differences among the substitute parts?

A: Molex 0741640050 and 0741640150 are supplied in tube packaging. TE Connectivity 7-102570-2 is supplied in tray packaging. Packaging format may affect handling, storage, and automated assembly processes but does not impact electrical or mechanical performance.

Q: Does the TE Connectivity 7-102570-2 offer any performance advantages?

A: The 7-102570-2 specifies operating temperature range (-65°C ~ 105°C) and current rating (3A), providing defined performance parameters not listed for the original part or the Molex alternatives. If your application requires these specifications, the TE Connectivity part offers documented performance data. The phosphor bronze contact material and thermoplastic insulation also match the original design materials more closely.

Q: Can I use these parts interchangeably in the same assembly?

A: Yes, all three substitute parts meet the core mechanical and electrical requirements for the 68645-023. However, verify that your PCB layout and mating connector design accommodate the minor dimensional variations noted in contact length and insulation height. The TE Connectivity part shows slight variations (0.318" vs. 0.315" mating contact length; 0.400" vs. 0.420" insulation height) that may require design review in space-constrained applications.
