Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the NDFR16H must maintain functional and electrical equivalence based on the following critical parameters:

Electrical Compatibility: Hexadecimal circuit configuration with 16-position selection, 100mA current rating, and 5VDC voltage rating are non-negotiable for direct substitution.

Mechanical Compatibility: Through-hole, right-angle mounting orientation with 0.100" (2.54mm) pitch and PC pin termination style ensure PCB layout compatibility without redesign.

Contact System: Beryllium copper contacts with gold finish provide the electrical performance and reliability characteristics required for this application class.

Environmental Compliance: RoHS3 compliance and MSL Level 1 rating ensure regulatory alignment and manufacturing process compatibility.

The FD01FR16H-S qualifies as a substitute part based on matching hexadecimal circuit type, 100mA current rating, and 5VDC voltage specification from the same manufacturer, ensuring functional equivalence within the defined parameter set.
