Substitute Part Grouping Explanation

Substitution of the 51760-10102401AA is determined by strict equivalence across the following critical parameters:

• Connector Type & Style: Receptacle with female sockets and blade sockets, blade power configuration
• Position Count & Layout: 26 total positions (24 signal, 2 power) in 4-row arrangement
• Pitch & Spacing: 0.100" (2.54mm) pitch maintained across all rows
• Mounting Configuration: Board edge, through-hole, right-angle orientation
• Termination Method: Solder termination for PCB integration
• Contact Specifications: Gold or Gold GXT™ finish at 30.0µin thickness
• Environmental Ratings: UL94 V-0 flammability, -20°C to 105°C operating range
• Mechanical Features: Board lock and guide pin functionality

The substitute part 51760-10102401AALF maintains identical electrical and mechanical specifications while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 51760-10102401AALF is the direct functional equivalent of the obsolete 51760-10102401AA. Both connectors share identical electrical and mechanical specifications across all critical parameters including position count, pitch, mounting configuration, contact finish, and environmental ratings.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 51760-10102401AA is classified as obsolete, indicating discontinued manufacturing and limited availability. The 51760-10102401AALF maintains active product status with current manufacturing support and improved compliance posture. The substitute part achieves RoHS compliance and REACH compliance status, addressing modern regulatory requirements for electronic component procurement.

For new designs or system refreshes, the 51760-10102401AALF is the appropriate selection. For legacy system maintenance where the original part number is specified, the 51760-10102401AALF provides direct substitution without design modification or re-qualification requirements.

Frequently Asked Questions (FAQ)

Q: Are these connectors mechanically interchangeable? A: Yes. Both the 51760-10102401AA and 51760-10102401AALF maintain identical mounting configurations, pitch spacing, and board edge interface geometry. No mechanical redesign is required for substitution.

Q: What is the difference between these part numbers? A: The primary differences are product status and compliance certifications. The 51760-10102401AA is obsolete with RoHS non-compliant status. The 51760-10102401AALF is active production with RoHS and REACH compliance. The suffix "ALF" indicates tray packaging and updated compliance specifications.

Q: Can I use the substitute part in existing assemblies designed for the original part? A: Yes. The 51760-10102401AALF is a direct substitute with no electrical or mechanical design changes required. Existing PCB layouts, connector mating interfaces, and signal routing remain unchanged.

Q: What is the contact finish specification for both parts? A: Both parts feature gold or gold GXT™ contact finish at 30.0µin (0.76µm) thickness, providing equivalent electrical performance and corrosion resistance.

Q: Are there packaging differences between these parts? A: The 51760-10102401AA packaging is not specified in the product data. The 51760-10102401AALF is supplied in tray packaging. Confirm packaging requirements with your procurement specifications.

Q: What is the operating temperature range for these connectors? A: Both connectors operate across -20°C to 105°C, with UL94 V-0 flammability rating and MSL 1 (unlimited) moisture sensitivity level.

Q: Why should I transition from the obsolete part to the active equivalent? A: The obsolete 51760-10102401AA has limited inventory availability and no ongoing manufacturing support. The 51760-10102401AALF ensures long-term supply chain stability, current manufacturing quality standards, and compliance with modern regulatory requirements including RoHS and REACH.
