Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0876312019 is based on strict alignment of the following critical parameters:

• Connector Type: Header with male pins and blades
• Position Count: 28 positions
• Pitch: 0.100" (2.54mm)
• Row Configuration: 4 rows
• Mounting Method: Board edge, through-hole, right-angle orientation
• Termination Method: Solder
• Contact Layout: 24 signal and 4 power contacts
• Contact Finish: Gold plating
• Operating Temperature Range: -20°C to 105°C
• Flammability Rating: UL94 V-0

The Amphenol ICC (FCI) 51720-10202402AALF meets all these parameters and qualifies as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol ICC (FCI) 51720-10202402AALF is a direct functional equivalent to the obsolete Molex 0876312019. Both connectors share identical electrical and mechanical specifications across all critical parameters. The Amphenol part carries active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain equivalent compliance certifications including UL94 V-0 flammability rating and RoHS compliance. The Amphenol connector offers the additional option of GXT™ contact finish while maintaining the standard 30.0µin gold plating thickness. Selection of the Amphenol part eliminates obsolescence risk while preserving full functional compatibility with existing board designs and mating connectors.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 51720-10202402AALF be used as a direct replacement for the Molex 0876312019?

A: Yes. Both connectors share identical specifications for connector type, position count, pitch, row configuration, mounting method, termination, contact layout, contact finish thickness, flammability rating, and operating temperature range. The parts are mechanically and electrically interchangeable.

Q: What is the primary reason for substitution?

A: The Molex 0876312019 is classified as obsolete. The Amphenol ICC part is active and maintains full supply availability.

Q: Are there differences in contact finish options?

A: The Molex part specifies gold contact finish at 30.0µin thickness. The Amphenol part offers gold or gold with GXT™ finish, both at the same 30.0µin thickness specification. Standard gold finish ensures compatibility.

Q: Do both parts meet the same compliance standards?

A: Both parts meet UL94 V-0 flammability requirements and RoHS compliance. The Molex part is ROHS3 compliant while the Amphenol part is RoHS compliant. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the packaging difference?

A: The Molex part packaging is not specified in available data. The Amphenol part is supplied in tray packaging.

Q: Are the board lock and mating guide features identical?

A: Yes. Both connectors include board lock and mating guide features as standard.
