Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0876224003 is determined by strict equivalence across the following critical parameters:

• Connector Type: Receptacle with female sockets and blade sockets
• Position Count: 30 positions
• Pitch: 0.100" (2.54mm)
• Row Configuration: 4 rows
• Mounting Method: Through-hole solder termination
• Contact Layout: 24 signal, 6 power distribution
• Mechanical Features: Board lock and guide pin integration
• Contact Finish: Gold plating at 30.0µin (0.76µm) thickness
• Environmental Compliance: UL94 V-0 flammability rating, operating range -20°C to 105°C

The Amphenol ICC (FCI) 51750-002LF meets all these criteria and is identified as the manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol ICC (FCI) 51750-002LF is the direct substitute for the obsolete Molex 0876224003. Both connectors maintain identical electrical and mechanical specifications across all critical parameters, including position count, pitch, row configuration, contact layout, and termination method.

The 51750-002LF offers the advantage of active product status, ensuring ongoing availability and supply chain support. Both connectors meet identical compliance requirements: UL94 V-0 flammability rating, RoHS compliance, and EAR99 export classification. The operating temperature range and moisture sensitivity levels are equivalent.

The contact finish specifications are compatible, with the 51750-002LF offering optional GXT™ enhanced gold plating in addition to standard gold finish, both at the specified 30.0µin (0.76µm) thickness.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 51750-002LF be used as a direct replacement for the Molex 0876224003?

A: Yes. The 51750-002LF meets all electrical and mechanical specifications of the 0876224003, including connector type, position count, pitch, row configuration, contact layout, mounting method, and termination. Both connectors feature identical board lock and guide pin integration.

Q: Are there differences in contact finish between these connectors?

A: Both connectors feature gold plating at 30.0µin (0.76µm) thickness. The 51750-002LF offers an optional GXT™ enhanced gold finish variant in addition to standard gold, providing flexibility in contact finish selection while maintaining the same thickness specification.

Q: What is the significance of the 4-row configuration?

A: The 4-row configuration with 30 total positions accommodates the specified contact layout of 24 signal and 6 power contacts. This arrangement is maintained identically in both the original and substitute connector.

Q: Are packaging differences relevant to substitution?

A: The Molex 0876224003 is supplied in standard packaging, while the Amphenol ICC 51750-002LF is supplied in tray packaging. Packaging format does not affect electrical or mechanical compatibility and is a logistics consideration only.

Q: Do both connectors meet the same environmental and compliance standards?

A: Yes. Both connectors are rated UL94 V-0 for flammability, operate across the identical temperature range of -20°C to 105°C, maintain MSL 1 (Unlimited) moisture sensitivity level, and comply with RoHS and EAR99 export requirements.
