Substitute Part Grouping Explanation

Substitution of the Molex 0876323018 is determined by strict alignment of the following critical parameters:

Position Count: 48 positions (non-negotiable)
Pitch: 0.100" (2.54mm) standard spacing
Mounting Configuration: Board edge, through-hole, right-angle orientation
Connector Type: Receptacle with female sockets and blade sockets
Contact Layout: 40 signal and 8 power contact arrangement
Termination Method: Solder attachment
Contact Finish: Gold plating at 30.0µin (0.76µm) thickness
Flammability Rating: UL94 V-0 compliance
Operating Temperature Range: -20°C to 105°C
Moisture Sensitivity: MSL 1 (Unlimited)

The Amphenol ICC (FCI) 51760-10404004AALF meets all these critical parameters and qualifies as a direct substitute. Both connectors share identical mechanical and electrical specifications within the allowed parameter set.

Engineering Selection Recommendations

The Amphenol ICC (FCI) 51760-10404004AALF is a qualified substitute for the obsolete Molex 0876323018 based on the following engineering criteria:

Compliance Alignment: Both connectors meet UL94 V-0 flammability requirements and maintain identical operating temperature ranges (-20°C to 105°C). The Amphenol part carries active RoHS compliance status, whereas the Molex part is ROHS3 compliant. Both satisfy moisture sensitivity requirements at MSL 1.

Mechanical and Electrical Equivalence: The connectors share identical position counts (48), pitch spacing (0.100"), mounting configuration (board edge, through-hole, right-angle), and contact layout (40 signal, 8 power). Solder termination and gold contact finish specifications are matched at 30.0µin thickness.

Product Availability: The Amphenol part maintains active product status with current inventory availability, addressing the obsolescence of the original Molex component. The Molex part is no longer in active production.

Contact Finish Options: The Amphenol substitute offers standard gold finish or enhanced GXT™ gold finish, providing flexibility for specific application requirements while maintaining the 30.0µin thickness specification.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 51760-10404004AALF be used as a direct replacement for the Molex 0876323018?

A: Yes. Both connectors share identical specifications for position count (48), pitch (0.100"), mounting type (board edge, through-hole, right-angle), contact layout (40 signal, 8 power), termination method (solder), contact finish (gold at 30.0µin), flammability rating (UL94 V-0), and operating temperature range (-20°C to 105°C). The connectors are mechanically and electrically equivalent.

Q: What is the primary reason for substitution?

A: The Molex 0876323018 is classified as obsolete and no longer in active production. The Amphenol ICC part is actively manufactured and available, making it the appropriate choice for new designs and system maintenance.

Q: Are there differences in compliance certifications?

A: The Molex part carries ROHS3 compliance, while the Amphenol part carries RoHS compliance. Both meet the required environmental and safety standards. The Amphenol part's RoHS status reflects current regulatory compliance for active products.

Q: Does the Amphenol part offer any additional features?

A: The Amphenol ICC 51760-10404004AALF offers an optional GXT™ gold contact finish in addition to standard gold plating. Both finish options maintain the 30.0µin thickness specification and are compatible with the original application requirements.

Q: What packaging is available for the substitute part?

A: The Amphenol ICC part is supplied in tray packaging. Verify packaging requirements for your specific procurement and assembly processes.

Q: Are the moisture sensitivity levels equivalent?

A: Yes. Both connectors are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
