Obsolete — Sourcing the 1278705-3 Today
TE Connectivity lists the 1278705-3 as obsolete. No official replacement or cross-reference part number has been published. If a direct-form-fit replacement exists from TE, it has not been assigned a successor code under this base number.
Compatibility Check Before Specifying
The 1278705-3 is listed for use with SC connectors. The angled exit routes the cable at 90° to the connector axis, which helps in tight panel layouts or where the cable must run parallel to the mounting surface. The 37.00 mm overall length includes the boot body plus the angled snout — measure the available clearance on your panel or adapter bulkhead before committing.
