Substitute Part Grouping Explanation

Substitution of the 51907-003 is determined by strict equivalence across the following critical parameters:

• Connector Type & Style: Header with male pins and blades, blade power configuration
• Position Count & Layout: 28 total positions with 24 signal and 4 power contacts
• Pitch & Row Configuration: 0.100" (2.54mm) pitch across 4 rows
• Mounting & Termination: Board edge, through-hole, right-angle mounting with solder termination
• Contact Specifications: Gold or Gold, GXT™ finish at 30.0µin (0.76µm) thickness
• Environmental Ratings: UL94 V-0 flammability, -20°C ~ 105°C operating temperature range
• Mechanical Features: Black color, mating guide included

The substitute part 51720-10202402ABLF maintains full electrical and mechanical compatibility with the 51907-003 across all specified parameters while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 51720-10202402ABLF is the direct functional equivalent to the 51907-003. Both components share identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch, mounting configuration, contact finish, and environmental ratings.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 51907-003 is classified as obsolete and does not meet RoHS compliance requirements. The 51720-10202402ABLF maintains active product status with full RoHS compliance and REACH compliance documentation, making it the appropriate selection for new designs and ongoing production requirements.

For applications currently using the 51907-003, direct substitution with 51720-10202402ABLF is supported without design modification, as all mechanical and electrical interfaces remain unchanged.
