Substitute Part Grouping Explanation

Substitution of the 51730-083 is determined by strict equivalence across the following critical parameters:

• Connector Type & Style: Header with male pins and blades, blade power configuration
• Electrical Configuration: 18 positions with 16 signal and 2 power contacts
• Mechanical Compatibility: 0.100" (2.54mm) pitch, 4-row configuration, board edge through-hole right-angle mounting
• Termination Method: Solder termination
• Contact Properties: Gold or Gold GXT™ finish at 30.0µin thickness
• Environmental Ratings: UL94 V-0 flammability, -20°C to 105°C operating range, MSL 1

The substitute part 51720-10101601AALF maintains full electrical and mechanical compatibility with the original 51730-083 while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 51720-10101601AALF is the direct functional equivalent for the obsolete 51730-083. Both connectors share identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch, mounting configuration, and contact properties.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 51730-083 is obsolete and carries RoHS non-compliant status, while the 51720-10101601AALF maintains active product status with RoHS compliance and REACH affected designation. For new designs or systems requiring ongoing component availability, the 51720-10101601AALF is the appropriate selection. For legacy system maintenance where the original 51730-083 is already deployed, the 51720-10101601AALF provides direct substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 51720-10101601AALF be used as a direct replacement for the 51730-083 in existing assemblies?

A: Yes. Both connectors maintain identical specifications for connector type, position count, pitch, mounting method, termination, contact finish, and environmental ratings. No design changes are required for substitution.

Q: What is the difference between these two part numbers?

A: The 51730-083 is an obsolete part with RoHS non-compliant status. The 51720-10101601AALF is the active equivalent with RoHS compliance and REACH affected designation. All electrical and mechanical parameters are identical.
