Frequently Asked Questions (FAQ)

Q: Are the 51760-11102003AA and 51760-11102003AALF physically interchangeable?

A: Yes. Both connectors share identical dimensions, mounting configurations, pitch, number of positions, and contact arrangements. They are direct physical substitutes.

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

A: The primary differences are product status, compliance certifications, and packaging. The 51760-11102003AALF is an active product with RoHS and REACH compliance, while the 51760-11102003AA is obsolete and RoHS non-compliant. The substitute uses tray packaging instead of bulk.

Q: Can I use the 51760-11102003AALF in existing designs originally specified for the 51760-11102003AA?

A: Yes. The substitute part maintains full electrical and mechanical compatibility. No design changes are required for direct substitution.

Q: Are there any performance differences between these connectors?

A: No. Both parts have identical contact finish specifications, flammability ratings, operating temperature ranges, and electrical contact layouts.

Q: What is the significance of the "ALF" suffix in the part number?

A: The "ALF" suffix indicates the tray packaging format and RoHS compliance status of the substitute part, distinguishing it from the bulk-packaged, non-compliant original.

Q: Is the 51760-11102003AALF suitable for new designs?

A: Yes. As an active product with current compliance certifications, this part is appropriate for new design implementations.
